    DESCRIPTION

    Injection mold and process for the manufacture of an optical module for a vehicle lighting device, and optical module manufactured by said mold and / or by said procedure. 5

    The present invention relates to an injection mold and a method for manufacturing an optical module for a vehicle lighting device. In addition, the present invention also relates to an optical module manufactured by said mold and / or by said method. 10

    Background of the invention

    In the field of vehicle manufacturing it is important to reduce the manufacturing processes of its different components and make them more versatile and modular. It is a great advantage to ensure that certain components or parts of the vehicle can be used for the largest number of different vehicles.

    In the case of the optical modules of a vehicle, for example, of the fog lights on the rear of the vehicle, these assemblies need to be placed in different orientations 20 depending on the vehicle due to design criteria, available space ... even so, It is necessary to comply with the current approval regulations, which makes modular manufacturing difficult.

    An optical module of a vehicle is formed by a plurality of parts, among which 25 are included one or more optics and a support of said optical (s), each optic having a surface finish, which may be different and be oriented differently depending on the vehicle where it should be mounted. These optical modules are usually manufactured by means of an injection mold that obtains both the support and the optics in the same injection. 30

    Thus, injection molds are known that implement additional and optional stages of over-injection of an optical module. These optional stages allow the resulting product to be provided with a certain modularity. It is obvious, then, that only the different characteristics will be introduced in case of performing the optional stages, the common process being the same. In case of requiring differentiated characteristics in the mandatory stages
    of the product, the aforementioned solution is not suitable for this.

    Therefore, the objective of the present invention is to provide a mold and a method for the manufacture of an optical module for a vehicle lighting device that can be manufactured in a versatile and modular manner, so that the optical module 5 can be use in different vehicles, making the minimum changes or modifications on the injection mold.

    Description of the invention
     10
    With the mold and the process of the present invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.

    The injection mold according to the present invention for the manufacture of an optical module for a vehicle lighting device, wherein the optical module 15 comprises at least one optic and one support of the at least one optic, comprises at least one injection nozzle, a slide plate and an ejection plate, where a molding cavity for the manufacture of the optical module is defined by the slide plate and the ejection plate when the injection mold is closed, where the injection mold comprises a first mounting plate coupled to the slide 20 plate, and at least one punch that fits the first mounting plate in a first mounting position, where the at least one punch is through the slide plate further delimiting the cavity of molding, and where the at least one punch defines a first surface finish of the at least one optic of the optical module.
     25
    Consequently, it is an injection mold comprising the common components of at least one injection nozzle, a mobile base, a fixed base, at least one ejector element, cooling elements ... where the injection cavity is delimited at least by a first component, slide plate, and a second component, ejection plate, when the mold is closed. The slide plate, on the face opposite the face that delimits the molding cavity, comprises fastening means of a first mounting plate. At least one punch is held by the first mounting plate, crossing both the first mounting plate and the slide plate, further defining the molding cavity. In this way, a first surface finish of the at least one optic is defined on the optical module. 35

    It is therefore emphasized that it is possible to obtain different optical modules by simply changing the position of the punch inside the injection mold, depending on the surface finish that is desired for the or each optical of the optical module. With the mold according to the invention, optical modules can be manufactured in the most versatile and modular way possible.
     5
    It should be noted that in the present description an optical module is understood as any component adjacent to a light emitter, so as to allow the direction or properties of the light beams emitted by said light emitter to be altered. Thus, the optical module will comprise at least one optic, for example, a Fresnel lens or a field aperture lens encompassed by the light emitter. Mention that the at least one optic and the support are obtained from the same injection, the support being the element that does not provide functionality at the optical level to the optical module but allows, for example, to position and hold the optics in a correct position with regarding light emitters.

    Therefore, the use of the first mounting plate induces the mounting of the at least one punch in a first position within the injection mold. Consequently, this first mounting position of the at least one punch implies a first surface finish of the at least one optic of the optical module.

    Advantageously, the injection mold according to the present invention comprises a second mounting plate coupled to the slide plate and the at least one punch fits the second mounting plate in a second mounting position, so that the first Mounting plate is exchanged for the second mounting plate, defining a second surface finish of the at least one optic of the optical module.
     25
    With this second mounting plate, which is interchangeable with the first mounting plate, it is possible to easily change the surface finish that is desired to be provided to the optics or optics of the optical module, allowing the optical module to be manufactured in a modular manner. Therefore, the use of the second mounting plate induces the assembly of the at least one punch in a second position within the injection mold. Consequently, this second mounting position of the at least one punch implies a second surface finish of the at least one optic of the optical module. First and second surface finishes are different, so, only by exchanging the first mounting plate for the second mounting plate, a modular optical module is achieved, with the same support but with differences in the surface finish of the at least one optical . 35

    According to a preferred embodiment, the first mounting plate comprises at least a first hole and the at least one punch comprises a fitting element so that the fitting element allows coupling at least a first hole defining the first mounting position, and / or the second mounting plate comprises at least a second hole and the at least one punch comprises a fitting element so that the fitting element allows a coupling to at least a second hole defining the second mounting position.

    It is thus observed that the at least one punch has a fitting element, which will be coupled to the first mounting plate or the second mounting plate in a certain position. Therefore, the same punch is used that will be mounted in a first or second mounting position on the first or second mounting plate depending on the coupling between the fitting element in the first or second hole. The punch mounting position will be unique and will perform the safety element function at the same time, since it prevents the punches from being engaged in an incorrect position on the mounting plate. In addition, if the mounting plate comprises more than one hole for the simultaneous coupling of more than one punch, it prevents the wrong punch from being placed in the wrong hole.

    Advantageously, the fitting element of the at least one punch comprises a groove and the at least one first hole comprises at least a first protrusion, so that the groove allows a coupling at least one first protrusion defining the first mounting position, and in addition, the fitting element of the at least one punch comprises a groove and the at least a second hole comprises at least a second protrusion, so that the groove allows a coupling at least 25 a second protrusion defining the second mounting position .

    Consequently, a first embodiment is described in which the combination of protrusion and groove forces a certain punch to be mounted in a certain position within the mounting plate. More in detail, a first combination of the first protuberance with the punch groove forces the punch to be positioned according to a first mounting position. In addition, a second combination of a second protrusion with the punch groove forces the punch to be positioned according to a second mounting position. Thus, depending on the position of the protuberance in the hole of the mounting plate, the orientation in which the punch is assembled in the injection mold varies. In addition, 35 in case there is more than one punch per mounting plate, varying the geometry of the
    Extrusion, in accordance with the punch groove, prevents a punch from being assembled in the wrong position inside the injection mold.

    It is noted that an embodiment has been presented in which the at least one punch comprises a groove in its fitting area and the at least one hole comprises a protuberance. Alternatively, the embodiment is evident in that the at least one punch comprises a protrusion in its engagement zone and the at least one hole comprises a groove. The result would be equivalent, forcing the assembly of the punch in a certain orientation on the mounting plate, as well as the assembly of the punch in the corresponding hole. Similarly, the use of a plurality of slits 10 complementary to a plurality of protrusions would be equally valid.

    In addition, the at least one first hole comprises at least a first geometry so that the fitting element of the at least one punch allows a coupling to the first geometry of the at least a first hole, defining the first mounting position, 15 and / or the at least a second hole comprises at least a second geometry so that the fitting element of the at least one punch allows a coupling to the second geometry of the at least a second hole, defining the second mounting position.

    Accordingly, a second embodiment is described in which the combination of the geometry of each hole and the geometry of the fitting element forces a certain punch to be mounted in a certain position within the mounting plate. More in detail, a first combination of first geometry with the punch engagement element forces the punch to be positioned according to a first mounting position. In addition, a second combination of second geometry with the punch engagement member forces 25 to position the punch according to a second mounting position. Thus, the geometry correspondence of the hole and fitting element define a unique position of the punch in the mounting plate. In addition, if there is more than one punch per mounting plate, each different geometry of the hole, according to the punch geometry, prevents a punch from being assembled in the wrong position inside the injection mold. 30

    According to a preferred embodiment, the at least one punch comprises a plurality of saw teeth on the surface that delimits the molding cavity, so that the plurality of saw teeth define the first surface finish of the at least one optic of the optical module . In addition, these saw teeth also define the second surface finish when the punch is in the second mounting position. Thus,
    The first or second position of the punch on the mounting plate defines that the plurality of saw teeth are located in one or another orientation within the molding cavity. Thus, the surface finish of the optics of the optical module can only be modified by exchanging the first mounting plate for the second mounting plate.
     5
    It should be noted that said surface finish may be, for example, a plurality of grooves made by said punch saw teeth on the optics or optics, or any suitable engraving.

    According to a possible embodiment, the injection mold according to the present invention comprises at least three punches mounted on the first mounting plate and / or on the second mounting plate, so that the at least three punches define the at least three surface finishes of the at least three optics of the optical module.

    Thus, for example, the three optics can have surface finishes formed by grooves, 15 but the grooves of each optics are oriented differently.

    According to this embodiment, one of the at least three punches may comprise a fitting element of substantially different size than a fitting element of at least one other of the at least three punches. twenty

    Accordingly, a third embodiment is described, which allows each of the three punches to be installed in the correct position of the mounting plate. This alternative allows not to confuse the position of the punches on the same mounting plate. Note but that this third embodiment can be combined with the first 25 or second embodiment, thus allowing, thanks to the first or second embodiment, that each punch is in a certain orientation within its orifice of each mounting plate, and thanks to the third embodiment described, each punch is in its correct hole inside the mounting plate.
     30
    Advantageously, the first mounting plate and / or the second mounting plate comprise at least one projection through the slide plate, further defining the molding cavity, so that the at least one projection defines a reference in the optical module . Thus there is a new element that delimits the molding cavity in order to reference the optical module resulting from the present invention. It is especially advantageous since a mark is introduced in the identifying optical module of the mounting plate
    used, being quickly recognizable what kind of optics has been implemented in said optical module.

    In addition, the injection mold according to the present invention advantageously comprises a fixing plate provided with a plurality of fixing elements 5 for retaining the at least one punch. Thus, the fixing plate allows the fixation of the punch or punches in the injection mold. On the contrary, the mounting plate guides and positions the at least one punch inside the injection mold.

    According to a second aspect, the present invention relates to a method for manufacturing by means of an injection mold of an optical module for a vehicle lighting device, where the injection mold comprises at least one injection nozzle, a plate slide, an eject plate, at least one mounting plate coupled to the slide plate and at least one punch that fits at least one mounting plate, where a molding cavity for the manufacture of the optical module 15 is defined by the slide plate, the ejection plate and the at least one punch, when the injection mold is closed, comprising the following steps:
    - select one of the at least one mounting plate for the removable mounting of the at least one punch, where the at least one punch defines a surface finish of at least one optics of the optical module; twenty
    - attach the at least one mounting plate to the slide plate;
    - adjust the at least one punch to the mounting plate according to a predetermined surface finish; and
    - inject a material into the molding cavity, manufacturing the optical module.
     25
    With the method according to the present invention, an optical module is manufactured in a versatile and modular manner. Thus, only by choosing and fixing a mounting plate on the slide plate, is an optical module with at least one different optics than the resulting when fixing another mounting plate on the slide plate. Each slide plate defines a specific orientation and position of the at least one punch within the injection mold, so that it defines a certain surface finish of the at least one optic of the optical module.

    In addition, the at least one mounting plate comprises at least one hole, and the at least one punch comprises a fitting element, and the step of adjusting the at least one punch at 35 the mounting plate comprises fitting the at least one punch in the at least one hole
    according to a mounting position. In this way, the position of the punch is defined and there is no possibility of error in positioning the at least one punch within the injection mold. This positioning is fast and efficient, without requiring additional elements that can increase the cost of the whole.
     5
    According to a preferred embodiment, the material injected at the stage of injecting a material into the molding cavity is polycarbonate, which possesses optimal properties to meet the optical and mechanical requirements of the optical module.

    According to a third aspect, the present invention also relates to an optical module 10 obtained with the mold described above and / or by the method described above.

    It should therefore be noted that the present invention allows obtaining an optical module that modifies the surface finish properties of the at least one optic that defines the optical module without the need to use an independent and different injection mold. Thus, as explained, the only additional element used is a second mounting plate. Note, then, that the at least one punch is common and is not required to be exchanged for the definition of different surface finishes. Thanks to the fitting of the at least one punch on the at least one hole of the first mounting plate or on the second mounting plate, a first or second mounting position results which, in turn, determines a first or second surface finish of the at least one optic of the optical module. In this way, modularity is achieved in obtaining an optical module with the same injection mold.

    Description of a preferred embodiment
     fifteen
    An embodiment of the mold according to the present invention is shown in Figure 1.

    According to this embodiment, the mold comprises a molding cavity 1 defined by an ejection plate 6 and a slide plate 5, inside which an optical module 2 is formed, which is formed by one or several optics 21 and a support 22 of the optics. twenty

    The slide plate 5 is provided with a plurality of holes 51 on which a mounting plate 31, 32 is mounted. It should be noted that in the present description, in the claims and in the drawings reference is made to two mounting plates, indicated by reference numbers 31 and 32. However, these two plates 31, 32 are not used at the same time, but are used alternately.

    Each mounting plate 31, 32 comprises a plurality of holes 310, 320 and a projection 33, and will be described in greater detail below with reference to Figures 2 and 3.
     30
    In addition, the mold also comprises a fixing plate 7 also provided with a plurality of holes for the placement of corresponding fixing elements 71, which allow fixing the at least one punch 4 in the injection mold.

    In order to form a surface finish of each optic 21, the mold also comprises a plurality of punches 4, each provided with a fitting 41.
    In figures 2 and 3 the interaction between the mounting plates 31 and 32 and the corresponding punches 4 can be seen. Thus, the first mounting plate 31 determines a first mounting position of the at least one punch 4, defining from thus a first surface finish of the at least one optic 21 of the optical module 2. By exchanging the first mounting plate 31 for the second mounting plate 32, said second mounting plate 32 determines a second mounting position of the at least one punch 4, thus defining a second surface finish of the at least one optics 21 of the optical module 2. Note that the at least one punch 4 is common, varying only its orientation in the injection mold, thus allowing to obtain optical modules 2 different.
     10
    Thus, according to a first embodiment, each mounting plate 31, 32 comprises a plurality of holes 310, 320 and may comprise a protuberance 311 associated with each hole 310, as can be seen in Figure 2.

    On the other hand, each punch 4 can comprise a fitting element 41 provided with a groove 411, the groove 411 being complementary to the first protuberance 311 of the first mounting plate 31. In this way a unique positioning of the punch 4 is achieved. on the first mounting plate 31, without the possibility of errors of placement or use of an incorrect punch 4 with a first mounting plate 31 that does not correspond to it. On the other hand, the groove 411 of the fitting member 41 of the same punch 4 fits into the second protuberance 321 of the second complementary hole 310 of the second mounting plate 32, defining a second mounting position in the injection mold.

    In Figure 3 it can be seen that alternatively and according to a second embodiment, the holes 310 can have different geometric shapes, always in correspondence with fitting elements 41 of the punches 4, also avoiding errors of placement or use of the punches 4.

    The possibility of changing the position of the punches 4 allows to vary the surface finish of each optic 21, being able to use the same mold to manufacture optical modules with 30 different optics.

    In order to modify the surface finish of the at least one optic 21 of the optical module 2, the at least one punch 4 comprises a plurality of saw teeth on the surface that delimits the molding cavity 1. Thus, as and as can be seen in figure 5, 35 according to an embodiment where the optical module 2 comprises three optics 21
    distributed longitudinally in the support 22, it is sought to modify the orientation of the plurality of saw teeth.

    More specifically, a modular concept is sought where the support 22 of the optical module 2 is mounted on different inclinations with respect, for example, the horizontal direction. In order to comply with the approval standards of this optical module 2, the optics 21 that make up the optical module 2 cannot be tilted in the same way as the support 22 does for the different vehicles where the optical module 2 can be mounted. Thus, the plurality of saw teeth defining each optic 21 must be oriented in a specific direction in order to open the field of light beams emitted by a light emitter towards a certain direction. Figure 5 shows how the support 22 has different inclinations with respect to the horizontal direction but, on the other hand, the three optics 21 that form the optical module 2 remain in the same orientation for each of the two mounted optical modules 2.
     fifteen
    This modularity is achieved by modifying only the mounting plate. Thus, a first mounting plate 31 defines a first position of the three punches 4, so that the plurality of saw teeth are oriented in a certain direction, so that a first surface finish of the three optics 21 is defined. on the contrary, a second mounting plate 32 defines a second position of the three punches 4, so that the plurality of saw teeth are oriented in a certain direction, so that a second surface finish of the three optics 21 is defined. Therefore, each mounting plate will define a surface finish of the optics 21 that make up the optical module 2.
     25
    Because the desired surface finish modification is a change in orientation of the plurality of saw teeth, the at least one punch 4 used is common. Due to the particular design of the hole in the mounting plate and the complementary design of the fitting 41 of each punch, the position of each punch 4 will be unique and predefined.
     30
    It is therefore understood that if a surface finish different from the at least one optics is desired, the use of an additional and different punch 4 that also has the corresponding fitting 41 is equally valid, thus being able to be mounted and correctly positioned in the corresponding mounting plate hole.
     35
    In the proposed embodiment which allows obtaining optical module 2 with
    three optics 21 of Figure 5, each of the two different optical modules 2 is achieved only by modifying a mounting plate. Thus, a first optical module 2 will be manufactured by mounting the first mounting plate 31 inside the injection mold. On the other hand, the second optical module 2 will be manufactured by mounting the second mounting plate 32 inside the injection mold. The same three punches 4 are used for both but with a different orientation in the injection mold.

    More in detail, a first punch 4 has a plurality of saw teeth designed to define a first surface finish of the first optic 21 of the optical module 2 so as to allow the light beams emitted by a light emitter to be opened in The 10 horizontal field. This first punch 4, due to the particular fitting element 41, can only be mounted, for example, in the first left hole 310 of the first mounting plate 31 and in the second left hole 320 of the second mounting plate 32. Thus :
    -By adjusting between the groove 411 of the fitting member 41 of the punch 4 and of the first protuberance 311 of the first hole 310 of the first mounting plate 31, the plurality of saw teeth of the punch 4 will be oriented perpendicularly to the support 22 of the optical module 2. Consequently, the left optics 21 will have a plurality of vertical walls that allow the light beams emitted by a light emitter in the horizontal field to be opened.
    -On the contrary, by adjusting between the groove 411 of the fitting member 41 20 of the punch 4 and of the second protuberance 321 of the second hole 320 of the second mounting plate 32, the plurality of saw teeth of the punch 4 will be oriented at 45 ° of the support 22 of the optical module 2. Consequently, the left optics 21 will also have a plurality of vertical walls that allow the opening of the light beams emitted by a light emitter in the horizontal field, by using 25 of the same punch 4, even with the support 22 inclined.

    This explanation would be common for the rest of the punches 4 used for the manufacture of the optics 21 of an optical module 2. It should also be noted that the positioning of the punch 4 has been explained in detail according to a first embodiment based on the engagement 30 between the groove 411 of the fitting 41 and protrusion of the hole in the mounting plate. This positioning is equally valid with the second embodiment explained, where a particular geometry of the hole complementary to that of the fitting member 41 of the punch 4 forces said punch 4 to a unique position within the mounting plate. 35

    The present invention also relates to a process for the manufacture of an optical module for vehicle lighting devices using the mold described above.

    The process according to the present invention comprises the following steps:

    First, a mounting plate 31 or 32 is selected for the removable mounting of a punch 4 or several punches, the or each punch 4 defining a surface finish of the optical (s) 21 of the optical module 2.
     10
    Next, the chosen mounting plate 31 is attached to the slide plate 5 and one or more punches 4 in the holes 310 are fitted to the mounting plate 31 according to a predetermined surface finish.

    In order for the mounting plate 31 to be fixed correctly, the fixing plate 7 15 with its fixing elements 71 is used, as can be seen in Figure 4.

    Finally, a material is injected into the molding cavity 1, for example polycarbonate, manufacturing the optical module 2.
     twenty
    Although reference has been made to a specific embodiment of the invention, it is evident to one skilled in the art that the mold and the process described are susceptible of numerous variations and modifications, and that all the mentioned details can be substituted by others. technically equivalent, without departing from the scope of protection defined by the appended claims. 25
