    Description Guide device for casting tool
    The present invention relates to a guide device for a casting tool.
    In casting tools, especially in injection molding and die casting tools, it is known to use so-called oblique slides for the production of castings with undercuts. These inclined slides are arranged inclined to the direction of movement of the parts of the mold. In the area in which the oblique slide engages the casting, this usually has a head.
    With the end opposite to the head, which is also referred to as the connecting end, the oblique slides are held on a movable device, which may be an ejecting device and in particular an ejector block.
    The movable device usually consists of two plates, an upper and a lower movable plate, which can represent in particular Auswerferplatten. The upper movable plate is also referred to as a holding plate and the lower movable plate as a base plate. In the upper movable plate openings are introduced, through which the connecting end of the inclined slide, which is applied to the head, can be introduced. The openings in the upper movable plate have a larger cross section in the lower area than in the upper area. In the lower region of the opening, a block, which is also referred to as a foot, is introduced from below into the opening, which is connected from below to the lower end of the oblique slide or a connecting piece to the inclined slide, in particular screwed. To compensate for movements that must perform the lower end of the inclined slide when ejecting the casting, the length of the block is less than the length of the extended opening, in which this is introduced. Thus, a clearance is created by the block in the expanded opening. The block or foot can thus be moved, in particular displaced, within the lower, widened part of the opening in the longitudinal direction of the opening.
    This known type of slanted slide guide has a number of disadvantages. On the one hand, it is necessary for a reliable sliding of the foot in the widened opening that the tolerances in the manufacture of the foot and the movable plate as well as the attachment of the foot to the oblique slide are accurately maintained. In addition, since a screwing of the foot with the oblique slide or a connecting part is required, the cost of producing and assembling the casting tool considerably.
    The object of the present invention is therefore to provide a guide device for a casting tool, in particular a pressure or injection molding tool, in which a reliable guidance of an inclined slide can be realized in a simple manner. In particular, the manufacture and assembly of the guide device and thus of the casting tool should be simple and yet the smoothest and most reliable possible movement of the oblique slide.
    The invention is based on the finding that this object can be achieved by providing a sliding fit of the oblique slide within the fit, via which the oblique slide is connected to the casting tool, in particular the ejector block.
    According to the invention the object is achieved by a guide device for casting tool having at least one inclined slide with at least one contour. The guide device is characterized in that the guide device has at least one movable device, in particular an ejector device, and at least one dowel pin, the dowel pin is held in at least one axle receptacle in the movable device, the axis of the dowel pin lies in the direction of the contour and the oblique slide is held over the dowel pin for axially displaceable holding the oblique slide on the movable device.
    As a guide device, the device is referred to, by means of which a movement of the inclined slide of a casting tool is supported, that is, by means of which at least a portion of the inclined slide is guided. In particular, a casting tool is understood to be a tool in which the material for forming a workpiece is injected into a casting mold and the material solidifies there. In particular, a casting tool or injection molding tool is referred to as a casting tool according to the invention.
    As an inclined slide is understood in the context of the invention, a slider for demolding or removal of a casting workpiece from the casting tool. In particular, a part of the casting tool is understood as an inclined slide, as a mold jaw, in particular for the manufacture of casting workpiece with
    Undercuts, is used. The inclined slide is arranged inclined to the direction of movement of the parts of the casting tool, which form the mold. Also to the movable device and the direction of movement of the inclined slide is arranged inclined.
    As a movable device according to the invention a generally arranged below the mold device is called, which is movable in the vertical direction. Preferably, the movable device is an ejector. The mold preferably consists of a contour insert and an upper mold block. Between the contour insert and the upper mold block there is a cavity into which the material from which a workpiece is to be formed can be introduced. The movable device may for example consist of two plates, which are also referred to as movable plates. Here, the lower plate is also referred to as the base plate and the upper plate as a holding plate.
    Directional statements, as above and below, refer to the components of a casting tool, where the contour insert is arranged below the upper mold block, unless stated otherwise. If the contour insert is not arranged horizontally, information such as horizontal or vertical in relation to the main orientation of the contour insert shall be transmitted. For example, in a casting tool in which the main orientation of the contour insert is in the vertical direction, embodiments and references made hereafter with respect to the horizontal are to be transferred to the vertical.
    According to the invention, the guide device comprises a dowel pin. As a dowel pin according to the invention denotes a pin over which the slanted slide is held directly or indirectly on the movable device. The dowel pin is held according to the invention in an axis recording in the movable device. As an axis recording a space is referred to, which is formed in the movable device and in which the dowel pin rests with a part of the lateral surface and preferably also with the end faces.
    The axis of the dowel is according to the invention in the direction in which the contour is located on the inclined slide. For example, if the contour is provided on the front side of the inclined slide, the axis of the dowel pin extends in the direction from the front to the rear of the slanting slide.
    The oblique slide is held axially displaceably on the movable device via the dowel pin. The inclined slide can thus move in the direction of the axis of the dowel pin.
    In addition, since the axis of the dowel pin is in the direction of the contour of the oblique slide, the oblique slide can be moved so that the contour can be released.
    In contrast to blocks or feet according to the prior art, in which the guide or storage is formed by a corresponding extension of an opening in the underside of the upper movable plate, in particular the upper Auswerfplatte, is in the guide device according to the invention a
    Sliding seat formed by the dowel pin. As a result, the parts whose mutual tolerances for a smooth guiding or sliding of the inclined slide are required, components which are independent of the movable plate. As a result, the production of the casting tool can be simplified as a whole.
    According to one embodiment, the oblique slider on a
    Connecting end has a passage for the dowel pin and the dowel pin is partially received in the passage. As a connecting end of the inclined slide here the axial end of the inclined slide is referred to, which is opposite to the axial end on which the contour is provided. The dowel pin is partially received in the passage which is inserted at this connection end. The projection of the dowel pin, where it is not received in the passage, can then serve for mounting on the movable device, in particular in an axis recording of the ejector. The biasing slide can be moved along the axis of the dowel pin.
    According to a further embodiment, the guide device has at least one fitting block with at least one connecting part for connecting to a connecting end of an inclined slide, the fitting block has a passage, the passage is offset from the connecting part and is perpendicular to the axis of the connecting part, and the dowel pin is partially received in the passage of the fitting block for axially displaceable holding of the fitting block and projects beyond at least one end of the passage of the fitting block.
    In this case, a block of material is understood as meaning a block of material which at least partially serves to produce a fit, in particular a sliding fit. The fitment block according to the invention has a connection part for connection to one end of an inclined slide. The connecting part, which can also be referred to as a hinge part and which is provided on the fitting block, is in particular a hinge pin, which can be guided through one end of the oblique slide and about which the oblique slide can be pivoted. Alternatively, it is also possible that the fitment block has a holder for a hinge pin, which is firmly connected to the oblique slide. The joint via which the oblique slide is connected to the fit block, preferably serves to pivot the oblique slide in a vertical movement of the lower end of the oblique slide relative to the horizontal. In particular, a translational movement is converted into a rotational movement by the joint.
    The connecting part according to the invention may be a connecting pin which extends through the passage at the connecting end of the inclined slide. The connecting pin can be held on the fit block. Thus, a joint is formed between the fitment block and the oblique slide, through which a further movement of the oblique slide is possible. The fitment block is secured to the moveable device by means of a passageway therein in which a dowel pin is partially received and which projects beyond at least one end of the passageway. For this purpose, as described above, the supernatant of the dowel pin can be held in an axis recording on the movable device. The dowel pin is partially received in the passage of the fitting block for axially displaceable holding of the oblique slide, that is inserted into this. The dowel protrudes beyond at least one end of the passage of the registration block. In particular, at least one end of the dowel pin projects beyond one side of the fit block.
    The fit block of the guide device according to the invention also forms with a further part of the casting tool, in particular a part of the movable device, in particular the ejector, a guide of the lower end of the inclined slide. According to the invention, a passage is provided for this purpose in the fit block. A passage is defined as an opening which extends over at least part of the width of the fit block and ends at at least one side of the fit block, that is to say is open on at least one side of the fit block.
    The passage is arranged offset in the fitment block to the hinge part, in particular the hinge pin. Arranged as staggered is understood a passage which is at least in the height direction of the fit block to the hinge part spaced. Particularly preferably, the passage is below the hinge pin in the fitment block. According to the invention, passage is also provided perpendicular to the axis of the joint part in the fitment block. The passage lies in a plane which is parallel to the plane in which the joint part lies. By the axis of the joint part, in particular of the hinge pin is thus perpendicular to the passage in the vertical projection from the top of the fitting block, a number of advantages can be achieved, which will be explained later in more detail.
    According to the invention, the guide device comprises a dowel pin. The dowel pin is partially received in the passage of the fitting block for axially holding the fitting block, that is, inserted into it. Axial displacement is understood as a displacement of the fit block along the axis of the dowel pin.
    The dowel protrudes beyond at least one end of the passage of the registration block. In particular, at least one end of the dowel pin projects beyond one side of the fit block.
    By the dowel pin is partially received in the fitment block and thereby the fitment block is mounted on the dowel pin, the fitment block can be moved on the dowel pin. In this way, the bearing of the fit block is displaced into the interior of the fit block. In contrast to blocks or feet according to the prior art, in which the guide or storage is formed by a corresponding extension of an opening in the bottom of the upper Auswerfplatte, in the guide device according to the invention, a sliding fit is formed in the interior of the fit block, which cooperates with the dowel pin works. As a result, the parts whose mutual tolerances are required for a smooth guiding or sliding of the fit block, components which are independent of the movable device, in particular the ejector. As a result, the production of the casting tool can be simplified as a whole. In addition, since the fit or the sliding fit is formed between the fitting block and the dowel pin, by changing the surfaces of the passage and / or the dowel pin, an increase in easy running is easily possible.
    In addition, by the axis of the joint part, in particular of the hinge pin is perpendicular to the passage and thus introduced into the passage dowel pin, by a vertical movement of the lower Schrägschieberendes up or down, pivoting of the inclined slide and thus one lying at least partially in the horizontal Movement be carried out. The horizontal movement is guided by the fit block on the dowel pin. The direction of movement of the lower end of the oblique slide in the horizontal is in this case perpendicular to the hinge axis of the joint part. In particular to the axis of the hinge pin. By the axis of the dowel over which the fit block and thus also the oblique slide are also in the direction of movement of the lower end of the oblique slide can allow the storage by means of dowel pin and passage some movement in this direction and thus the freedom of movement of the oblique slide be increased overall. As a rule, an additional guide is provided on a part of the casting tool which is arranged above the movable device, in particular the ejection device, in particular in the region of the casting mold, for example the contour insert, via which the vertical movement of the oblique slide and the pivoting are limited.
    By the dowel pin is partially received in the fitment block and thereby the fitment block is mounted on the dowel pin, the fitment block can be moved on the dowel pin. In this way, the bearing of the fit block is displaced into the interior of the fit block. In contrast to
    Blocks or feet according to the prior art, in which the guide or storage is formed by a corresponding extension of an opening in the underside of the upper Auswerfplatte is in the guide device according to the invention a sliding fit inside the
    Passage block formed, which works by interaction with the dowel pin. As a result, the parts of their mutual tolerances for a smooth guiding or sliding of the fitment block are required, components which are independent of the movable plate, in particular the ejector. As a result, the production of the casting tool can be simplified as a whole. In addition, since the fit or the sliding fit is formed between the fitting block and the dowel pin, by changing the surfaces of the passage and / or the dowel pin, an increase in easy running is easily possible.
    In addition, by the axis of the connecting part, which is also referred to as a connecting or hinge pin to the passage and thus the inserted into the passage dowel pin is vertical, by a vertical movement of the lower slide gate end up or down, a pivoting of the oblique slide and thus an at least partially horizontal movement are carried out. The horizontal movement is guided by the fit block on the dowel pin. The direction of movement of the lower end of the oblique slide in the horizontal is in this case perpendicular to the hinge axis of the joint part. In particular to the axis of the hinge pin. By the axis of the dowel over which the fit block and thus also the oblique slide are also in the direction of movement of the lower end of the oblique slide can allow the storage by means of dowel pin and passage some movement in this direction and thus the freedom of movement of the oblique slide be increased overall. As a rule, an additional guide is provided on a part of the casting tool which is arranged above the movable device, in particular of the ejector block, in particular in the region of the casting mold, for example of the contour insert, by means of which the vertical movement of the oblique slide and the pivoting are limited.
    According to a preferred embodiment, the passage extends over the entire width of the oblique slider at its connecting end and both ends of the dowel pin protrude beyond the ends of the passage. As a result, the dowel pin can be held on both sides of the connecting end of the inclined slide.
    According to a preferred embodiment, the passage extends over the entire width of the fit block. As a result, a two-sided support or storage of the fit block in a receptacle is possible. Particularly advantageous in this embodiment, both ends of the dowel pin project beyond the ends of the passage. The length of the dowel pin is therefore greater in this embodiment than the length of the passage. An additional on the sides of the Passungsblockes where the passage exits, provided bracket is therefore not required, but the holder can be made exclusively on the ends, in particular the projections of the dowel pin.
    Preferably, the running behavior is improved in the axial movement of the oblique slider or fit block at the contact surface between the dowel pin and the passage in the connecting end of the oblique slide or the fit block. For this purpose, the surface of the dowel pin and / or the surface of the passage, that is to say the inside of the passage can be surface-treated or it can be introduced between the surfaces of a material for increasing the smooth running, that is, in particular for reducing the frictional forces. According to a preferred embodiment, the guide device therefore comprises a sleeve which is received in the passage in the connecting end of the oblique slide or in the fitting block and through which the dowel pin extends. By the sleeve is a separate component to the dowel pin and the oblique slider or the fitting block, the material from which the sleeve is made, can be selected according to the requirements for the reduction of the frictional force. Other requirements, such as in particular force or
    Holder of other parts are not placed on the sleeve, in contrast to the fitment block itself.
    According to a preferred embodiment, the length of the sleeve is less than the length of the dowel pin. In this embodiment, the holder of the oblique slide or the fitting block is carried on a further part of the casting tool, in particular the movable device and preferably the ejector exclusively on the dowel pin. The requirements that are to be placed on the material of the sleeve are limited to improving the operability of the dowel pin in the sleeve.
    According to one embodiment, however, the length of the sleeve is greater than the width of the oblique slide or the fitting block. In this embodiment, at least one end of the sleeve projects beyond at least one side of the oblique slide or fit block. As a result, the production of the guide device according to the invention is further simplified. In particular, a fastening of the sleeve to the oblique slide or the fit block on the projection of the sleeve can be made so that structural changes of the oblique slide or the fitting block and in particular the passage in the oblique slide or the fit block are not required.
    According to one embodiment, the sleeve has at least one recess on its circumference. The depression is preferably at least in the outer circumferential surface of the sleeve. In addition, the depression or recesses are each provided in the region of the ends of the sleeve. Particularly preferably, the depression is provided in the part of the sleeve which, when installed, projects beyond the side of the oblique slide or the fitting block. By providing a recess in the sleeve, in particular in the supernatant via the oblique slide or the fit block, this can be fixed in a simple manner to the oblique slide or fit block. For example, a pin or other connecting element can be partially inserted into the recess and an axial displacement of the sleeve in the fitment block can be prevented.
    Particularly preferably, a groove is provided as a recess. This groove preferably represents an annular groove, that is, extends over the entire circumference of the sleeve.
    Alternatively or additionally, the sleeve may have an elevation at one of the ends. The increase, for example, represent a flange. The elevation also preferably extends over the entire circumference of the sleeve and projects outward in the radial direction. By such an increase, the sleeve can be held on one side of the passage of the oblique slider or fit block. At the opposite end of the sleeve may be provided a recess.
    According to a preferred embodiment, the guide device has a Seegering. The Seegering is provided in particular for cooperation with the sleeve for fixing the sleeve on the inclined slide or the fit block. The clamping ring acts on a projection of the sleeve on the side of the oblique slide or the fit block. Particularly preferably, the clamping ring engages in a groove, in particular annular groove in the outside of the sleeve. As a result, an axial displacement of the sleeve in the oblique slide or the fit block is prevented in a simple manner.
    The cross section of the dowel pin can according to the invention have various shapes. For example, the cross section may be round, oval or angular, for example rectangular. According to a preferred embodiment, the dowel pin is a cylindrical pin. This embodiment has the advantage that the dowel pin is easy to manufacture due to the round cross section. In addition, the production of a passage and a sleeve with a round cross section is easier than the production of a passage and a sleeve with, for example, rectangular cross-section. Another advantage of a dowel pin with round
    Cross-section, in particular a cylindrical pin, is that a tilting in an axial movement of the dowel pin in the oblique slide or the fitting block, in particular in a sleeve in the oblique slide or the fitting block, is not to be feared.
    According to the invention, the guide device has at least one axle receptacle for receiving at least one part of at least one of the ends of the dowel pin. The axle receptacle is preferably formed by one or more recesses in which at least a part of the end of the dowel pin is held. In the case of a dowel pin with a round cross section, the axle mount preferably provides a receptacle with a circular cross section. The diameter of the axle receptacle preferably corresponds to the outer diameter of the dowel pin. As a result, a firm hold of the dowel pin is guaranteed. Alternatively, the diameter of the axle receptacle but also be greater than the outer diameter of the dowel pin. In this embodiment, the dowel pin is then preferably held on the end faces by corresponding end faces of the axle.
    The axle receptacle preferably forms part of a receptacle in the movable device, in particular the ejection device. Particularly preferably, the receptacle also comprises a cutout for a fit block or the connection end of the oblique slide for accommodating at least the fit block, in addition to the axis receptacle. By the axle receptacle is part of a receptacle in which also the fitment block is received, the manufacture and in particular the introduction of the receptacles in the movable device, in particular the ejection device, is simplified.
    According to a preferred embodiment, the receptacle, which comprises at least the axle receptacle and preferably the cutout for a fitting block or the connecting end of the inclined slide, is movable in the upper through a depression, which is also referred to as an axis receiving recess
    Plate, in particular the ejector plate, which is also referred to as a holding plate, and formed by a recess which is also referred to as axis receiving recess in the lower movable plate, in particular the ejector plate, which is also referred to as the base plate. By dividing the recording on the holding plate and the base plate, the introduction of the recording is simplified in particular with a round cross-section of the axle. In particular, undercuts in the individual movable plate, in particular the ejector plates are not required. In addition, a simple introduction of the dowel pin and guided on the dowel pin connection end of the oblique slider or fitment block is ensured by dividing the recording on the support plate and base plate.
    According to a preferred embodiment, the fitting block or the connecting end of the oblique slider is inserted into a recess for a fitting block or the connecting end of the oblique slider whose width is greater than the width of the fitting block or the connecting end of the inclined slide. The width of the fit block is understood to mean the dimension in the horizontal, which is perpendicular to the axis of the joint part, in particular of the hinge pin. Thus, the width of the fitment block is the dimension that is parallel to the axis of the passageway. The width of the fit block can be, for example, 10 mm, preferably 15 mm, smaller than the width of the fit receiver. By having the clearance larger in width than the interference block or the connecting end of the oblique slider, the interference block can move in the widthwise direction of the clearance. This movement is guided by the bearing formed by the dowel pin in the passage. In addition, the cutout preferably has a contour which corresponds to the outer contour of the fit block or of the connection end of the inclined slide. In this way, a rotation of the fit block about the axis of the dowel pin, in particular with a round cross section of the dowel pin can be prevented. Particularly preferably, the fitment block has a rectangular cross section at least in the lower region and the cutout also has a rectangular cross section, at least in the lower region, which is preferably provided in the base plate. The depth of the registration block, that is, the dimension which is perpendicular to the width in the horizontal, preferably corresponds to the depth of the cutout. As a result, if necessary, an additional lateral guidance of the fit block in the fit recording takes place. In particular, however, a rotation of the fit block is prevented by the dowel pin thereby.
    The cutout is preferably formed by two cutout recesses in different parts of the casting tool, in particular in the retaining plate and the base plate. The cutout recess in the holding plate in this case represents a passage opening, that is, extends over the entire height of the holding plate. The cutout recess in the base plate, on the other hand, preferably represents a depression in the upper side of the base plate, that is to say comprises a base.
    According to a preferred embodiment, the sleeve is made of bronze. This material is both easy to process and also creates a high smoothness of the dowel pin in the sleeve and thus in the passage of the connecting end of the oblique slide or the fitting block. Particularly preferably, lubricant is also provided on the inside of the sleeve and / or the outside of the dowel pin, which further improves the ease of movement. In this case, solid lubricant, such as graphite particles, is preferably used.

    FIG. 1 shows an embodiment of a guide device 5 according to the invention in a casting tool 1.
    The casting tool 1 comprises an upper mold block 11 and a contour insert 12, which may also be referred to as a core block. The upper mold block 11 and the contour insert 12 together form the actual casting mold 10, in particular injection mold. The upper mold block 11 and the contour insert 12 can be moved towards and away from each other. In particular, for example, the upper mold block 11 can be raised.
    In the illustrated embodiment, an upwardly directed depression is provided in the underside of the upper mold block 11 and an upwardly directed elevation is provided on the contour insert 12. Between the recess and the elevation, in the merged state of the upper mold block 11 and the contour insert 12, a gap, which is also referred to as cavity 110, is formed.
    Below the casting mold 10 is a movable device, which is also referred to below as ejector 4 or ejector, is provided. As indicated by the arrow in Figure 1, the ejector 4 with respect to the mold 10 can be moved to and from this, that is, upwards and downwards. The ejection device 4 consists of a holding plate 40, which may also be referred to as an upper movable plate or upper ejector plate, and a base plate 41, which may also be referred to as a lower movable plate or lower ejector plate.
    Between the ejector 4 and the cavity 110 extend devices for ejecting the finished casting, in particular injection molded part or diecasting. In the illustrated embodiment, a slider 6 and an inclined slide 2 are shown. However, according to the invention it is also possible to provide a plurality of slides 6 and / or several oblique slides 2. The oblique slide 2 has at its upper end a head 20 on which a contour 200 is provided. The elongate main body of the oblique slide 2 is also referred to as a shaft 21. In the length of the shaft 21, this is guided via an additional guide 120, which is provided in the illustrated embodiment on the contour insert 12.
    At the lower end of the shaft 21, which is also referred to as the connecting end 211, the oblique slide 2 is guided via a guide device 5.
    If, by injecting material into the cavity 110, the casting piece, which is also referred to as an injection molding, has been formed, this can be removed by lifting the ejection device 4 and lifting the upper molding block 11 out of the casting mold.
    Here, the upper ends of the slide 6 and the head portion 20 of the inclined slide 2 come into contact with the injection molding.
    The lower end of the oblique slide 2 is, as shown in more detail in Figures 2 to 4, connected in one embodiment via a hinge with a fitment block 3. The fit block 3 has a box shape, in the upper side of a recess 30 is introduced so that the cross section of the fitting block 3 forms a U-shape in the upper region. Through the recess 30 extends the connecting part 31, which may also be referred to as a hinge pin, wherein the connecting part 31 passes through the two legs of the U-shape or ends in this. The connecting part 31 is in this case in the horizontal and extends through the connecting end 211 of the oblique slide 2. The oblique slide 2 can thus be pivoted about the axis of the connecting part 31, which is also referred to as the hinge axis. The pivoting of the oblique slide 2 is in this case limited in particular by the additional guide 120 on the core block 12.
    Below the recess 30, a passage 32 is introduced into the fitting block 3. In the illustrated embodiment, the passage 32 has a circular cross-section. The passage 32 is offset from the connecting part 31 perpendicular but also introduced horizontally in the fitment block 3.
    In the passage 32, a sleeve 34 is introduced. The length of the sleeve 34 is greater than the width B of the fit block 3. The ends of the sleeve 34 are thus beyond the sides of the fit block 3 addition. At this projection of the sleeve 34, a Seegering 35 is pushed onto the sleeve 34 in the illustrated embodiment. The Seegering 35 can engage in a (not shown) groove on the outside of the sleeve 34. In the sleeve 34, a dowel pin 33 is received. The length of the dowel pin 33 is greater than the length of the sleeve 34 and also greater than the width of the fitting block 3. Thus, the two ends of the dowel pin 33 in the central insertion into the sleeve 34 on the sleeve 34 and the sides of the fitting block 3 addition.
    The mounting of the inclined slide 2 on the ejector 4 will be described below with reference to Figures 5 and 6. In Figure 5, the holding plate 40 of an ejector is shown in a perspective bottom view.
    In the holding plate 40 a plurality of receiving recesses 43 are introduced. The receiving recesses 43 each include a cutout recess 4200 and an axle receiving recess 4210. The cutout recess 4200 has a rectangular cross section, in the illustrated embodiment with rounded corners. The cutout recesses 4200 also extend over the entire height of the retainer plate 40. The axle receiving recesses 4210 in the illustrated embodiment provide upwardly directed groove-shaped recesses. The axle receiving recesses 4210 close on two opposite sidewalls, which may also be referred to as end walls of the cutout recess 4200, at. The axis receiving recesses 4210 are thus unlike the recess recess 4200 not open upwards but limited upwards by the channel shape, in particular semicircular channel.
    If a diagonal slide 2 is to be guided on the receiving depression 43 in the holding plate 40, then this can be introduced together with the associated fitment block 3 from above through the receiving depression 43 and in particular the fit receiving depression 4200. In this state, at least the dowel pin 33 is not yet inserted into the passage 32. The sleeve 34 may already be provided in the passage 32 and optionally fixed by means of the Seegerings 35 on the fitment block 3. But it is also within the scope of the invention that the sleeve 34 and optionally the Seegering 35 are fixed only after the insertion of the inclined slide 2 in the receiving recess 43.
    The ends of the dowel pin 33, which protrude beyond the sides of the fitting block 3, are partially in the axis receiving recess 4210 of the receiving recess 43. In particular, a part length of the projection of the dowel pins 33 via the fitting block 3 with its upper half in the axis receiving recess 4210 of the upper ejector 40th
    The width of the mating block 3, which denotes the dimension in the direction of the passage 32, is smaller than the dimension of the free recess 4200 in this direction. As a result, a movement of the fit block 3 in the cutout recess 4200 by a certain amount is possible. On the other hand, the length of the dowel pins 33 is designed so that the dowel pin 33 abuts with its end faces on the end faces of the axle receiving recess 4210 in the state brought into the axle receiving recess 4210 of a receiving recess 43. Thus, the dowel pin 33 has no or little play in the axial direction in the receiving recess 43, and the fitting block 3 has a clearance in this direction corresponding to the difference between its width and the width of the release recess 4200.
    In the embodiment shown in FIG. 5, a plurality of receiving recesses 43 are shown in different orientations. By providing these differently oriented receiving recesses 43 a plurality of oblique slides 2 can be introduced for different injection moldings.
    FIG. 6 shows a perspective top view of a base plate 41. According to the receiving recesses 43 in the holding plate 40 a plurality of receiving recesses 43 are also introduced into the base plate 41. The contour of the receiving recesses 43 corresponds to the contour of the receiving recesses 43 in the holding plate 40 described above. In particular, these receiving recesses 43 also each have a cutout recess 4200 and two axle receiving recesses 4210 extending from the end faces of the cutout recess 4200. The axle receiving recesses 4210 are formed by downwardly directed depressions in the form of grooves. The cutout recesses 4200 in the base plate 41 have a fleas smaller than the thickness of the base plate 41. Thus, the cutout recesses 4200 in the base plate 41 do not constitute passages but depressions.
    If a retaining plate 40, which is not shown in FIG. 6 for better recognition, is placed on this base plate 41, the lower region of the fitting block 3 enters the recess recess 4200 in the base plate 41. The underside of the fitting block 3 lies on the bottom of the latter Freckungsvertiefung 4200 on. In addition, the lower half of the ends of the dowel pin 33 is held in the axle receiving recesses 4210 of the base plate 41.
    The assembled, that is the mounted, state of the guide device 5 is shown schematically in FIG. On the right side, an oblique slider 2 is shown in the home position and on the left side in the ejection position in which the ejector 4 is shifted upward. From Figure 7 it follows that the holding plate 40 and the base plate 41 are secured together so that the receiving recesses 43 of the upper and the lower ejector plate 40, 41 are superimposed. The receiving recesses 43 thus form together receptacles 42, in particular axle mounts 421 for the ends of the dowel pin 33 and mating mounts 420 for the mating block 3. Between corresponding axis receiving recesses 4210 in the retaining plate and the base plate 40, 41, the ends of the dowel pin 33 are held, which extends through extends the passage 32 in the fitting block 3. The upper side of the fitting block 3, in which the recess 30 is provided, is slightly offset upwards relative to the upper side of the retaining plate 40. The top of the fit block 3 can also lie flush with the top of the support plate 40. The connecting end 211 of the shaft 21 of the oblique slide 2 can thus in the recess 30 via the
    Joint pin 31 are pivoted. As can also be seen from FIG. 7, the width of the fit block 3 is smaller than the width of the cutout 420. Thus, the fit block 3 can be moved in the horizontal direction on the dowel pin 33 guided in the cutout 420.
    When vertical displacement of the ejector 4 consisting of the holding plate and base plate 40, 41 upwards, which is shown on the left side in Figure 7, the oblique slide 2 is pivoted about the hinge pin 31 slightly. This pivoting is supported by the additional guide 120 on the contour insert 12. The fit block 3 shifts in this pivoting of the inclined slide 2 in the receptacle 42. Since the friction is limited to the friction between the sleeve 34 and the dowel pin 33, the displacement in the receptacle 42 is substantially frictionless.
    8 shows a further embodiment of an inclined slide 2 with dowel pin 33 for a further embodiment of the guide device 5 is shown.
    In the embodiment shown in Figure 8, a passage 210 is introduced in the connecting end of the inclined slide 2. In the passage 210, a sleeve 34 is inserted, in which a dowel pin 33 is guided. The passage 201 is inserted in the direction of the contour 200 provided on the head 20 of the oblique slider 2. In particular, the passage extends through the side of the oblique slide 2 on which the contour 200 is provided. In the embodiment shown in FIG. 8, the passage 210 is not perpendicular to the longitudinal axis of the oblique slide 2.
    This embodiment of the oblique slider 2 with dowel pin 33 can be held on the Auswerfervorrichtung 4 shown in Figures 5 to 7. For this purpose, the dowel pin 33, as described above at the supernatants on the sleeve 34 addition, held in the axis receptacles 421 between the support plate 40 and the base plate 41. In this embodiment, the angle at which the
    Slanting slide 2 to the vertical is given by the angle in which the passage 210 is introduced into the inclined slide 2.
    The invention has a number of advantages. In particular, a smooth displacement of the oblique slide, optionally be ensured by a fitment block in a recording by the structure of the invention. In addition, the manufacture and assembly of the casting tool are simplified.
