    DESCRIPTION
    The present invention relates to a plastic housing for electronic devices, in particular remote controls.
    Such a plastic housing is known, for example, from DE 10 2010 045 944 A1. It comprises a first housing portion and a second housing portion, wherein the first housing portion comprises a joint surface oriented toward the second housing portion, and the second housing portion comprises a joint surface oriented toward the first housing portion and the two housing portions. housing parts are joined together so that they abut against each other at the joining surfaces.
    From US 2013/255875 A1 and US 7 008 240 B1 a plastic housing according to the preamble of claim 1. is known in each case, in particular the production differs in that at or on the miter surfaces there are formed support surfaces for attaching ejector pins, at which house parts are deepened.
    According to one aspect of the manufacture, a plastic housing for electronic devices, in particular remote controls, comprises a first housing part and a second housing part, the first housing part comprising a joint surface oriented towards the second housing part, and the second housing part comprising a joint surface which is oriented in the direction of the first housing part, where the two housing parts are joined together so that they abut against each other at the joining surfaces, and so that the joining faces are made as miter surfaces.
    The presented plastic housing is based on the assumption that the initially mentioned plastic housing contains molding elements which enlarge the joint surface, whereby the two housing parts have a wider working surface relative to each other. In the form-fitting elements, however, it is problematic that these must be precisely matched, since otherwise in the joined state of the plastic housing there is a gap left between the two housing parts which, above all in areas with high aesthetic requirements, can be disruptive . In order to avoid this gap and yet realize a large joint surface between the two housing parts, it is proposed with the presented plastic housing that the joint surfaces are made as miter surfaces.
    In a further development of the presented plastic housing, the miter surfaces of the housing parts are designed so that they at least partly run around an inner space arranged to accommodate an electronic component of the electronic apparatus. In this way, the miter surfaces extend in a V-shape and thus make it possible to center the two housing parts further in relation to
    DK 201800079 Y4 each other. Thus, the miter surfaces simultaneously perform the function of the previously mentioned mold-closing elements.
    In a further development of the presented plastic housing, the miter surfaces are designed to enter the interior space. In this way, all obtuse edges of the housing parts formed by the miter surfaces lie in the inner space of the plastic housing. At the obtuse edges, tools such as ejector pins, vent elements or the like can be placed in an especially advantageous manner in the interior space in the manufacture of the housing parts, so that any remaining burrs or the like are no longer visible afterwards.
    In a further development, the presented plastic housing is manufactured by a method in which a basic mold material is introduced into the mold cavities forming the housing parts and air is discharged from the mold cavities at the vent sites located on or adjacent to the mold cavities at which the housing parts miter surfaces are formed.
    The further development is based on the assumption that the basic mold material, when introduced into the mold space, displaces the air located there, so that the air must be discharged from the mold space. Normally, the air is discharged from the mold space by a separating plane between the tool parts forming the mold space. In order to ensure that the miter surfaces and thus the mold parts extend as far as possible to the exact pointed shape at the side of the remote control facing outwards, the separating planes at this location should be as close as possible so that no basic mold material enters the separating plane and thus leaves a grat with disruptive effect. In this close design of the partitions, venting of the mold space at the partition plane is practically excluded. Therefore, it is proposed that the venting site be placed at or next to the miter surface, preferably in the inner space of the plastic housing to be formed, so that the venting is, on one side, as close as possible to the miter surface to be formed and thus cannot burns, inclusions, or the like, which appear disruptive, while, on the other hand, at the same time, manufacturing-related burrs or the like are placed in the interior space of the plastic housing to be formed.
    In a further development of the presented method, ducts are used for draining air from the mold chambers, which ducts lead into the mold chambers and into which ejector pins are inserted. In this way, the air duct through which the air is diverted from the mold cavity is, on the one hand, kept very small, so that after a complete venting of the mold cavity, correspondingly smaller basic mold material also enters the vent duct. On the other hand, the exhaust duct is automatically cleaned by the ejection of the housing part in its basic form by means of the ejector pin.
    DK 201800079 Y4
    In a further development of the presented plastic housing, the base mold material is introduced into the mold cavities at injection points located on one side of the mold compartment opposite a side with the vent location.
    In a particular further development of the presented plastic housing, the injection points are seen in an injection direction for the base mold material located in the middle of the mold cavities. In this way, it is ensured that the base mold material can be evenly distributed in all directions in the mold space. However, it is also ensured that the base mold material penetrates the last areas of the mold cavity and thus does not cure prematurely there, which could clog the mold chamber.
    In yet another development of the presented plastic housing, the mold spaces are formed with mold plates, which, before the introduction of the basic mold material, are closed air-tight by a partition plane. In this way, the abovementioned grate is avoided at the partition plane in the mold space.
    In a preferred further development of the presented plastic housing, the miter surfaces of the housing parts to be formed end up in the separating plane.
    In a particularly preferred further development of the presented plastic housing, the vent sites at the miter surfaces are opposite the partition plane. In this way, it is ensured that burrs or the like arising from the venting are placed in the interior space of the plastic housing to be formed and are not visible from the outside.
    According to a further aspect of the manufacture, in a process for producing a plastic housing for one of the presented plastic houses, a basic molding material is introduced into a mold cavity forming the housing part, and the air is diverted from the mold cavity at a vent location adjacent to or adjacent to a place in the mold space at which the miter surface of the housing member is formed.
    In a further development of the presented method, a duct leading into the molding chamber and into which an ejector pin is inserted is used to divert the air from the mold space.
    In another further development of the presented method, the base mold material is introduced into the mold space at an injection point located at one side of the mold space opposite a side with the vent location.
    DK 201800079 Y4
    In a further development of the presented method, the injection point in this connection is located on a central axis of the mold space.
    In yet a further development of the presented method, the mold space is formed of two tool molds which are closed airtightly at a separating plane prior to the introduction of the basic mold material into the mold space.
    In a further development of the presented method, the miter surface of the housing part to be formed ends in the partition plane.
    In a particularly preferred further development of the presented method, the venting location lies at the miter surface opposite the partition plane.
    According to a further aspect of the manufacture, a housing portion of one of the presented plastic housings is manufactured by one of the methods presented.
    The characteristics, features and advantages of the present invention described above, as well as the manner in which they are obtained, become more understandable in the context of the following description of the exemplary embodiments, which will be more fully understood in connection with the drawings.

    In the figures, the same technical elements are provided with the same reference numerals and are described only once. The figures are purely schematic and, above all, do not represent the actual geometric conditions.
    Referring to FIG. 1, showing a remote control 1 for controlling an unspecified electronic apparatus such as, for example, a multimedia apparatus in a perspective view.
    The remote control 1 comprises a plastic housing 2 composed of a first housing part in the form of an upper bowl 3 and a second housing lower bowl 4, as well as two keyboards 5 with a large number of key elements 6. For the sake of clarity, the key elements 6 on the keyboard 5 are not all bearing a reference designation on the figures.
    Between the two keyboards 5 is a control intersection 8 comprising a first key element 9, a second key element 10, a third key element 11 and a fourth key element 12. The four key elements 9 to 12 are located above the scope and at a distance of 90 ° around a confirmation key 13.

For example, such a command can be entered as a directional command via the key elements 9 to 12, which then control the movement of a control element on the exemplary multimedia apparatus in one of the four possible directions of movement.
    DK 201800079 Y4
    The remote control 1 is illustrated solely by way of illustration, so that the subsequent technical embodiments become more understandable. However, they can be realized by any electronic device and especially by any remote control.
    The plastic housing 2 is manufactured by basic molding, which is explained in the following technical embodiments on the basis of injection molding. Figures 2a to 2c show sectional calculations of a permanent bowl shape 15 which provides a mold space 16 for injection molding of the bowl 3 in the plastic housing 2. On the other hand, sections 3a to 3c show sections of sectional drawings of a permanent bowl shape 17, providing a mold space 16 for injection molding of the saucer bowl 4 in the plastic housing 2.
    The permanent cover shape 15 comprises a pressure side 18, also called nozzle side 18. Opposite the pressure side 18, the permanent cover shape 15 comprises a closure side 19, also called ejector side 19. On the pressure side 18 and the closing side 19, the permanent cover shape 15 of clamping plates 20 is enclosed on to which the remaining elements of the permanent bowl shape 15 are carried.
    On the printing side 18, on the clamping plate 20 a mold plate 41 is shown, which is shown in FIG. 4, and in which a mold insert 21 is inserted. In the mold insert 21, a pressure die 22 is formed which forms the convex outer surface of the plastic housing 2 on the upper bowl 3.
    On the closure side 19, an ejector housing 23 is carried on the clamping plate 20 which, on the side opposite the clamping plate 20, is closed with a pressure plate 24. On the pressure plate 24 a mold plate 41 is carried on the closing side, which is shown in FIG. 6, and in which a mold insert 21 is inserted on the closure side. On the closure insert 21 on the closure side, a core 25 is formed which forms the concave inner surface of the plastic housing 2 on the upper bowl 3.
    The die 22 and the core 25 together form the overshoot mold space 16. Guide channels 26, in which ejector pins 27 have been passed, guide into the overshoot mold space 16 through the pressure plate 24 and the mold insert 21 on the closure side. In this connection, the guide channels 26 are provided with shoulders 28 which the ejector pins 27 could counter with corresponding corresponding shoulders 29. Of the shoulders 28 and the corresponding shoulders 29 are shown in FIG. 2a and 2b, for the sake of clarity, are not all shown with a reference designation. These shoulders 28, 29 are constructional in that a top portion of the ejector pins 27 is designed as a flat ejector, while the lower portion of the ejector pins 27 is manufactured as a round to improve fracture load capacity. In this connection, the flat ejectors of the ejector pins 27 are guided in the guide ducts 26, while
    The circular areas of the ejector pins 27 under the shoulders 29 are led into free bores which are not referred to further.
    The ejector pins 27 are supported on an ejector base plate 30 and are positioned in their position by means of an ejector retainer 31. The two plates 30, 31 are disposed movably in the interior of the ejector housing 23 so that the ejector pins 27 can be moved thereto.
    Throughout the pressure plates 24, tempering bores 32 pass on the pressure side 18 and also on the closing side 19 through which a tempering means such as water can be passed to temper the bowl mold space 16 by cooling or heating. For the sake of clarity, not all of these tempering bores 32 are provided with a reference designation. In this connection, the tempering bores 32 have a minimum distance to the mold space 16 which is 10 to 20 times smaller than the width of the upper bowl 3 of the plastic housing 2. For the minimum distance, 2 mm was chosen in the present embodiment. The diameter of the tempering bores 32 is between 4 and 5 times the minimum distance. In the present embodiment, this means between 8 mm and 10 mm. The larger the tempering bores 32 are, the faster the tempering is performed.
    The permanent saucer mold 17 is constructed in the same way as the permanent saucer mold 15. Therefore, FIG. 3a to 3c have the same reference numerals as in FIG. 2a to 2c. The foregoing explanations regarding the permanent bowl shape 15 are similarly applicable to the permanent bowl shape 17. Therefore, for the sake of brevity, a new version is waived.
    The only difference with respect to the permanent bowl shape 15 is that in the mold plate not shown for the permanent saucer mold 17 on the printing side 18, two mold inserts 21 are inserted which correspondingly guide several tempering bores 32 into the permanent saucer mold.
    The permanent bowl shape 15 and the permanent bowl shape 17, together with a further permanent shape 35, can be seen in FIG. 4 and 6, for making a battery cover, may be located in a common tool, which will be described in greater detail later.
    For the preparation of an upper bowl 3 and / or a lower bowl 4, a variothermal injection molding process is used. While injection molding, especially of plastics for tempering, is usually understood to mean cooling to dissipate the heat energy from the molten primer material, mold cavity 16 is heated by a variothermal injection molding process initially, prior to injection of the primer material, and then cooled again. IN
    In this connection, the mold insert 21 in the present embodiment is immediately tempered both on the printing side 18 and on the closing side 19, i.e. initially heated. In this way, it is particularly ensured by injection molding of high gloss housing parts 3, 4 that no weld seams are formed on the finished product.
    The respective mold space 16 is closed independently of the heating. For this purpose, the clamping plate 20 on the closure side is moved against the clamping plate 20 on the printing side 18 until the two mold plates 21, in which the die 22 and the core 25 are similarly formed, are in contact with each other.
    When the mold space 16 is closed and heated accordingly, the heated basic molding material is pressed via an inlet duct 34, which can be seen in FIG. 5 and 6, into the mold space 16. For a high-gloss plastic housing 2, as the basic molding material for the bowls 3, 4, methyl methacrylate-acrylonitrile-butadiene styrene, known as the abbreviation M-ABS, can be used. This basic molding material should be heated to 114 ° C before entering the molding chamber 16.
    The base mold material which is led into the mold space 16 is distributed there and displaces the air located there. This must be omitted accordingly, which will be described in more detail later.
    When the mold space 16 is filled completely with the base mold material, the mold inserts 21 are again cooled via the tempering bores 32 so that the base mold material is hardened. For this purpose, for example, cold water is driven through the tempering bores 32.
    The mold space 16 is then opened and the mold part thus produced is pushed out of the tool by means of the ejector pins 27. In this connection, the ejector base plate 30 presses the ejector pins 27 against the open mold space 16, so that the mold part manufactured, i.e. the upper bowl 3 or the lower bowl 4, loosens and thus can fall out of the tool. Then, the ejector pins 27 are retracted from the ejector retaining plate 31 again and the entire tool is reset to its original state so that the injection molding process can be re-initiated.
    In the present embodiment, the plastic housing 2 for the remote control 1 must be provided with as monolithic appearance as possible. Thus, when the upper bowl 3 and the lower bowl 4 are joined together at a joining surface 36, a butt joint between the two bowls 3, 4 must lie on an edge, so that there is no visible gap between the two bowls 3, 4. In this way, a viewing person could hardly see if the plastic housing 2 for the remote control 1
    DK 201800079 Y4 is a component in one or more parts. In this way, the remote control 1 gets a much slimmer appearance, especially when the upper bowl 3 is executed in a color contrast to the lower bowl 4.
    To achieve this, the joining surfaces 36 are performed on the two bowls 3, 4 in such a way that the two bowls 3, 4 can be connected to each other via a miter connection. Thus, the joining surfaces 36 are hereinafter referred to as miter surfaces 36. However, in the manufacture of the miter surfaces 36, it should be noted that cracks in the bowls 3, 4 to be produced can thereby occur at the wall thickness 37 of these which may cause defects. in the surfaces of the bowls 3, 4 to be manufactured. However, in order to achieve the monolithic effect mentioned above, the bowls 3, 4 at the miter surfaces 36 must be tapered as much as possible. This means that the wall thickness 37 is reduced from a normal wall thickness of, for example, 2 mm to a wall thickness of less than 0.2 mm. Therefore, using the previously explained injection molding process, it should be noted that the formation of surface defects such as burns at bowls 3, 4 is not favored due to the large cracks in the wall thickness 37.
    In principle, a separating plane 38 between the mold inserts can be used for the above-mentioned venting of the mold space 16. For this, however, there should be a gap left in the separating plane, through which the air from the mold space 16 can escape. However, when the mold cavity is completely vented, subsequent foundation mold material penetrates into it, resulting in the formation of burrs. However, these burrs are contrary to the desired monolithic appearance of the plastic housing 2, which is why a vent via the dividing plane 38 is not considered.
    For this reason, in the present embodiment, the ejector pins 27 are located in the region of the miter surfaces 36 towards the inside of the plastic housing 2 to be manufactured. The guide ducts 26 and the ejector pins 27 can thus be formed in such a way that there is a sufficient gap to be left between them, through which the mold space 16 can be vented.
    The advantage of this solution is that, when ejecting the manufactured mold part, i.e. one of the cups 3, 4, the guide ducts 26 can also be simultaneously cleaned through the movement of the ejector pins 27. In addition, the air, when ejecting the manufactured mold part, can again discharge the stools 26 .
    In addition, the mold inserts 21, each of which forms a mold space 16, must always be positioned exactly one above the other to ensure an accurately extending miter surface 36. This positioning will be explained in more detail below in the light of FIG. 4 to 6, which in one
    Similarly, a perspective view of Y4 shows one half on the printing side 39 and one half on the closure side 40 of an injection molding tool, in which the permanent cover mold 15, the permanent saucer mold 17 and the permanent battery cover mold 35 are formed together. In this connection, the mold inserts 21 are held to the corresponding permanent molds 15, 17 and 35 in the mold plates 41.
    In the cores 25 of the mold inserts 21 on the half of the closure side 40 there are further details which serve to make the bowls 3, 4. Thus, for example, FIG. 6 pin mold members 42 and sleeve mold elements 43 with which the cups 3, 4 can be formed with pins and sleeves according to the technical knowledge of DE 10 2010 045 944 A1 in order to be able to close the plastic housing 2 as screw-free as possible. Of these tab molding elements 42 and sleeve molding elements 43, not all have their own reference numerals in FIG. 6th
    In addition, FIG. 6 further resetting elements 44, with which the two halves 39, 40 can be pressed apart from each other in the mold cavities 16 after cooling of the base molds to the bowls 3, 4, in order to move the two halves 39, 40 towards each other in this movement. For example, guide columns 45 are secured at half of the pressure side 39 which can be inserted into corresponding guide bores 46 of the half of the closure side 40.
    The inlet channels 34 mentioned above are shown in FIG. 4 and 5, the representation 33 of FIG. 5 is indicated by an arrow in FIG. 4. The inlet duct 34 for the permanent bowl shape 15 opens into a collection bottom 54 of half on the closure side 40. In the collection bottom 54, the base mold material to be processed is collected and redirected so that the base mold material from the inlet duct 34 to the bowl 3 to be produced runs out. at an angle to its ejection direction. In this way, the inlet duct 34 is carried out as a tunnel inlet and the permanent overhead mold 15 as a separator mold.
    In order to ensure the above-mentioned exact position of the mold inserts 21 and thus an accurate configuration of the mold cavities 16, the halves 39, 40 are provided with a double centering. An initial centering roughly centers the two halves 39, 40 relative to each other. For this purpose, tool centering pins 47 are screwed at half on the pressure side 39 which, in connection with the closure of the molding space 16, engages in tool centering recordings 48 on the half on the closing side 40. For a fine centering, on the mold inserts 21 on the half on the pressure side 39, insertion centering pins 49 can be inserted. into mold insert centering recordings 50 in the mold inserts 21 on half of the closure side 40.
    DK 201800079 Y4
    In this connection, the mold centering pins 49 are made in smaller sizes than the tool centering pins 47, so that the coarse centering only works in connection with the closure of the mold space 16 and the fine centering is only used when it is largely completed.
    For a further reduction of potential surface defects on the shells 3, 4 of the plastic housing 2, the inlet ducts 34 and thus the injection points are placed on the center axes 51 of the mold chambers 16, so that the base mold material, when penetrated into the respective mold space 16, can be propagated and distributed uniformly there. In addition, it is thereby ensured that the base mold material eventually penetrates to the edge zones with the above-mentioned cracks in the wall thickness 37 forming the miter surfaces 36 and fills these regions of the mold space 16 uniformly. Furthermore, in this way it is ensured that the base mold material close to the inlet duct 34 does not cure prematurely due to a too thin mold space area.
    The bowls 3, 4, made with the above-described tool and method, can be assembled after ejection from the tool in a manner indicated in FIG. 7a, in a joining direction 52 to the plastic housing 2, thus accommodating an inner compartment 53 indicated in FIG. 7b, and in which, for example, a circuit board not shown in the form of electronics for the remote control 1 can be included.
    In connection with the composition of the upper bowl 3 and the lower bowl 4 in the joining direction 52, the two bowls 3, 4 are automatically centered at the miter surfaces 36. In this way, a level finish shown in FIG. 6b, between the outer cup 3 and the bottom cup 4 externally, thus ensuring the above-mentioned monolithic form of the plastic housing 2.
    An example of an internal view of the manufactured tops 3 and bottom cups 4 is shown correspondingly in FIG. 8a and 8b. Thus, the image of FIG. 8a and 8b to that formed by half on the closure side 40 of the tool forms.
    There are clearly visible support faces 55, which the ejector pins 27 act to correspondingly eject the upper bowl 3 or lower bowl 4 from the half on the closure side 40. The ejector pins 27 and thus the support faces 55 are formed in square form, the width of the square shape extending circumferentially around the upper bowl 3 or the saucer 4.
    The ejector pins 27, and thus the supporting faces 55, are located at an edge 56 of the upper bowl 3 or lower bowl 4 facing the interior space 53. In this way,
    The outer edges of the two bowls 3, 4 are finished level and so that the monolithic appearance of the remote control is not disturbed.
    Because of the ejector pins 27, the cups 3, 4 may be recessed at the support surfaces.
    In FIG. 8a and 8b there are also depicted pins 42 'and sleeves 43', which are formed correspondingly of 5 pin molding elements 42 and sleeve molding elements 43, for the sake of clarity, not all of which have their own reference designation. Furthermore, FIG. 8b is the location 34 'at which the inlet duct 34 of the lower bowl 4 ended. The corresponding location 34 'on the upper bowl cannot be seen in the perspective of FIG. 8a.
