Description

Technical Field

[0001] The present invention relates to an injection mold, in particular to an injection mold for left and right C-pillar upper decorative panels. Background Art

[0002] The structure of the decorative panels on the left and right C pillars is as shown in the attached Figure 1 As shown, its structure mainly includes a plate body a, a buckle piece b is provided on one side of the plate body a, and a edging c extends downward from the corner position of the plate body a. The edging c is located on the side of the plate body a away from the buckle piece b, and the edging c is used to wrap the corresponding C-pillar.

[0003] The edging c not only needs to fit stably on the corresponding C-pillar, but also needs to be installed in coordination with other covering decorative parts on the C-pillar. Therefore, a plurality of snap-fitting protrusions d need to be provided on the side wall of the edging c, and the snap-fitting protrusions d extend and protrude to both sides of the edging c.

[0004] Based on the above-mentioned structure of the decorative panel structure on the left and right C-pillars, during the corresponding injection mold design process, since the parting surface of the panel body a is parallel to the panel body a, and the extension direction of the edging c is perpendicular to the plane where the panel body a is located, the extension direction of the snap-fitting protrusion d on the edging c is parallel to the plane where the panel body a is located, a side core-pulling mechanism must be provided on the side of the panel body a where the snap-fitting piece b is provided. If a traditional left-right symmetrical core-pulling molding mechanism is adopted, not only will the overall size of the mold be large, but it will also interfere with the side core-pulling mechanism corresponding to the snap-fitting piece b, resulting in design difficulties. Summary of the Invention

[0005] In view of this, the first object of the present invention is to provide an asymmetric side-drawing molding mechanism, which has good edge quality for the plate body formed by injection molding and effectively controls the overall size of the mold.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] An asymmetric side-drawing forming mechanism includes a forming block assembly and a forming block driving member, wherein the forming block driving member includes a first driving member and a second driving member, and the forming block assembly includes a first forming block and a second forming block, wherein the first forming block is provided with a first forming end, and the second forming block is provided with a second forming end, wherein the first driving member includes a first driving source and a first driving slider group, wherein the first driving member drives the first forming block to slide via the first driving slider group, and the second driving member includes a second driving source and a second driving slider group, wherein the second driving member drives the second forming block to slide via the second driving slider group, wherein the first forming end and the second forming end are close to each other and are used to injection mold an edge portion with a snap-fitting protrusion on a decorative panel on a C-pillar;

[0008] The power output direction of the first driving source and the sliding direction of the second forming block are perpendicular to each other.

[0009] According to the above technical solution, during the injection molding process, the first driving member drives the first molding block to move, and the second driving member drives the second molding block to move. The first molding end of the first molding block and the second molding end of the second molding block are close to each other and cooperate to injection mold the edge position with the buckle convex point on the C-pillar upper decorative panel; when the actual product is demolded, the first molding end of the first molding block and the second molding end of the second molding block are separated from each other, so that a two-way demolding effect can be generated for the edge position with the buckle convex point on the injection-molded C-pillar upper decorative panel, and the edge quality of the injection-molded panel body is better.

[0010] In addition, since the power output direction of the first driving source and the sliding direction of the second forming block are perpendicular to each other, the transverse and longitudinal dimensions of the mold can be effectively controlled.

[0011] Preferably, the first driving source includes a driving cylinder, the first driving slider group includes a first driving block, one end of the first driving block is connected to the telescopic end of the driving cylinder, and the other end of the second driving block is wedge-fitted with the end of the first forming block away from the first forming end.

[0012] Through the above technical solution, the driving cylinder drives the first driving block to move, and a wedge-shaped fit is adopted between the first driving block and the end portion of the first forming block that is away from the first forming end. The first driving block can drive the first forming block to slide stably, and the movement stability is high.

[0013] The second object of the present invention is to provide an injection mold for left and right C-pillar decorative panels, which has good edge quality for the panel body formed by injection molding and effectively controls the overall size of the mold.

[0014] In order to solve the above technical problems, the technical solution of the present invention is:

[0015] An injection mold for left and right C-pillar upper decorative panels comprises a movable mold and a fixed mold. The first driving source is installed on the movable mold, and the second driving source is located on the fixed mold.

[0016] Through the above technical solution, the first driving source is set on the movable mold, and the second driving source is set on the fixed mold, which fully utilizes the structural characteristics of the injection mold. The edging quality of the injection-molded plate body is good, and the overall size of the mold is effectively controlled.

[0017] Preferably, the second driving source includes an inclined guide column fixedly connected to the fixed mold, the second driving slider group includes a second driving block, the second driving block is slidably connected to the fixed mold, the inclined guide column passes through the second driving block and is used to drive the second driving block to slide, and the second forming end is located at the end position of the second driving block.

[0018] Through the above technical solution, the inclined guide pin on the fixed mold drives the second driving block to slide. On the one hand, the installation position on the fixed mold is reasonably utilized; on the other hand, the driving cooperation relationship between the inclined guide pin and the second driving block is more stable.

[0019] Preferably, a molding groove is provided on the side wall of the second molding end close to the fixed mold, and an injection molding space is formed among the molding groove, the first molding end, the second molding end and the fixed mold.

[0020] Through the above technical solution, after the molten plastic enters the injection molding space, an extended plastic sheet structure will be formed at the end position of the edge, and the extended plastic sheet structure can have a structural reinforcement effect on the edge.

[0021] Preferably, the end surface of the second molding end located in the injection molding space is an injection molding surface, a molding plate is provided on the injection molding surface, and the second molding end is provided with an adjusting member, and the adjusting member is used to adjust the distance between the molding plate and the injection molding surface.

[0022] Through the above technical solution, the distance between the molding plate and the injection molding surface can be adjusted by the adjusting part. When the molding plate is attached to the injection molding surface, a single relatively thick injection-molded sheet is formed on the edge of the plate body injection-molded in the injection molding space; when a certain distance is generated between the molding plate and the injection molding surface, two injection-molded sheets can be injection-molded in the injection molding space, and the thickness of the two injection-molded sheets can be controlled by adjusting the distance between the molding plate and the injection molding surface; injection-molded sheets of different thicknesses are injection-molded to adapt to assembly requirements in different scenarios.

[0023] Preferably, the injection molding surface is divided into an upper molding surface, a lower molding surface, and a connecting surface. The upper molding surface and the lower molding surface are staggered in an upper and lower manner, and the connecting surface is connected between the upper molding surface and the lower molding surface.

[0024] The forming plate includes an upper plate, a lower plate, and a connecting plate. The upper plate is located on the upper forming surface, the lower plate is located on the lower forming surface, and the connecting plate is connected between the upper plate and the lower plate.

[0025] The connecting plate comprises an upper connecting plate connected to the upper mold plate and a lower connecting plate connected to the lower mold plate, and the upper connecting plate is slidably connected to the lower connecting plate.

[0026] Through the above technical solution, the thickness of the molded sheets injected at the upper and lower molding surfaces can be adaptively adjusted by adjusting the distance between the upper mold plate and the upper molding surface, and the distance between the lower mold plate and the lower molding surface. The thickness of the molded sheets injected at these two positions can be made different, thereby adapting to more different assembly requirements.

[0027] Preferably, the adjusting member includes two adjusting bolts, which correspond to the upper mold plate and the lower mold plate one by one. The adjusting bolts are threadedly connected to the second forming end, and the ends of the adjusting bolts pass through the forming groove and are rotatably connected to the corresponding upper mold plate and the lower mold plate.

[0028] Through the above technical solution, the positions of the upper and lower mold plates can be adjusted accordingly by independently rotating the adjusting bolts, which makes adjustment convenient and has high structural stability.

[0029] Preferably, two sleeves are further provided, and the sleeves are sleeved on the adjusting bolts one by one. The upper forming surface and the lower forming surface are both provided with sliding holes. One end of the sleeve is rotatably connected to the corresponding upper mold plate and lower mold plate, and the other end of the sleeve is slidably connected to the corresponding sliding hole.

[0030] Through the above technical solution, the sleeve can block the molten plastic outside the adjusting bolt, thereby improving the durability of the adjusting bolt.

[0031] Preferably, a nut is connected to the adjusting bolt, and the nut is used to abut and lock against the side surface of the second forming end.

[0032] Through the above technical solution, when the nut is locked against the second formed end, the position of the adjusting bolt can be effectively limited, and the structural stability is high. BRIEF DESCRIPTION OF THE DRAWINGS
