Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a novel tailgate lower trim panel mold. Background Technology

[0002] The tailgate trim panel is a decorative or functional component installed on the inside or outside of the bottom of the tailgate (trunk door), and is usually made of plastic, composite materials or metal.

[0003] In existing technologies, the production of the lower tailgate trim panel typically involves first injection molding a single piece of plastic as the main material, and then molding reinforcing ribs and clips onto this single piece of plastic during the injection molding process. Afterward, a velvet finish is applied to the surface of the main material, and finally, the lower tailgate trim panel is installed onto the tailgate using clips. This production method involves numerous steps, is complex, and is time-consuming.

[0004] Therefore, it is necessary to design a processing mold for the lower trim panel of the car tailgate with fewer production steps and higher processing efficiency. Utility Model Content

[0005] This application provides a novel tailgate lower trim panel mold to solve the technical problem of multiple production steps and low processing efficiency in the production of automotive tailgate lower trim panels.

[0006] This application provides a novel tailgate lower trim panel mold, comprising: a fixed mold and a moving mold; a first forming part is provided on the side of the fixed mold facing the moving mold, and a second forming part is provided on the side of the moving mold facing the fixed mold; a velvet mounting part for mounting velvet material is provided on the side of the fixed mold facing the moving mold, and a fiberglass board mounting part for mounting fiberglass board material is provided on the side of the moving mold facing the fixed mold; the surface of the second forming part is provided with a plurality of forming grooves for injection molding reinforcing ribs and buckles; each forming groove is provided with at least one injection port; each injection port is connected to an injection molding device; wherein, when the moving mold and the fixed mold are closed, the fiberglass board material is preheated and the side facing the velvet material is pre-coated with an adhesive material, the velvet material covers the first forming part, and the fiberglass board material covers the second forming part.

[0007] By adopting the above technical solution, the fiberglass board material and the velvet material are pressed and formed by the first molding part and the second molding part before injection molding to form the main body of the lower trim panel of the car tailgate. Then, the material is injected into the molding groove, and the reinforcing ribs and snap-fit ​​structure are directly injection molded on the fiberglass board. The pressing is completed by the closing of the moving mold and the fixed mold, and then injection molding is performed. This optimizes the process of covering the velvet surface after injection molding. At the same time, only the reinforcing ribs and snap-fit ​​structure need to be injection molded on the fiberglass board, which further reduces the time and material consumption required for production and improves production efficiency. In addition, using fiberglass board as the main material of the lower trim panel of the car tailgate achieves lightweighting and improves the noise reduction effect.

[0008] Preferably, the multiple forming grooves are distributed in a mesh pattern and are interconnected.

[0009] By adopting the above technical solution, all the molding grooves are interconnected, so that the reinforcing ribs and snap-fit ​​structure are integrally molded after injection molding to improve strength. At the same time, the mesh-distributed molding grooves make the reinforcing ribs distributed in a mesh on the fiberglass board, ensuring the strength of the lower trim panel of the car tailgate.

[0010] Preferably, the first forming part is recessed relative to the fixed mold surface, and the second forming part is protruding relative to the moving mold surface. The contour of the protrusion matches the contour of the recess.

When the moving mold and the fixed mold are closed, the first step structure and the second step structure are misaligned to cut the velvet material and the fiberglass board material.

[0011] By adopting the above technical solution, the fiberglass board material and the velvet material are pushed into the first forming part of the fixed mold through the protruding structure of the moving mold, and the material pushed into the first forming part by the second forming part is cut and separated from the whole material by the misalignment when the first step structure and the second step structure are engaged. This optimizes the cutting and trimming process after covering the velvet surface in traditional production, further reduces the number of processes and improves the processing efficiency.

[0012] Preferably, the injection molding device is equipped with multiple solenoid valves for controlling the injection process, each solenoid valve is equipped with an injection tube, and each injection tube is connected to a corresponding injection port.

[0013] By adopting the above technical solution, by setting up injection tubes to connect each injection port and injection device, and by controlling the on / off switching of each injection tube through solenoid valves, the injection process of reinforcing ribs and clips can be controlled, ensuring that the injection can be cooled and formed at the same time, improving the accuracy of injection and reducing the generation of waste.

[0015] By adopting the above technical solution, the maximum injection pressure of the injection molding device is set to 16.2MPa. Low-pressure injection avoids damage to the fiberglass board that supports the injection. At the same time, the twenty-four injection ports are spaced apart in the molding groove to achieve uniform injection of the reinforcing ribs and snap-fit ​​structure, reduce the time required to complete the injection, and further reduce the impact on the fiberglass board.

A first storage hole suitable for the insertion of the first hook is set on the moving mold, thereby improving the fit between the moving mold and the fixed mold.

[0018] Preferably, the fiberglass board mounting part includes a plurality of second pins, which are spaced apart above the second forming part. Each second pin is arranged parallel to the moving direction of the moving mold, and the fixed mold is provided with a plurality of second receiving holes suitable for the insertion of the second pins.

[0019] By adopting the above technical solution, multiple second pins are set to pierce and fix the fiberglass board material, thereby improving the efficiency of fiberglass board material installation and disassembly. A second storage hole suitable for the insertion of the second pin is set on the fixed mold to improve the fit between the moving mold and the fixed mold.

[0020] Preferably, the first forming part is provided with a first pressure plate driven by a cylinder, and the first pressure plate is arranged around the outer periphery of the recessed first forming part; the second forming part is provided with a second pressure plate driven by a cylinder, and the second pressure plate is sleeved on the outer periphery of the protruding second forming part; when the moving mold and the fixed mold are closed, the first pressure plate presses the velvet material and the fiberglass board material onto the second pressure plate.

[0045] Preferably, in the embodiment provided in this application, the mold is provided with two workstations, upper and lower, to realize the simultaneous production of two car tailgate lower trim panels. The middle part of the fixed mold 1 is recessed inward to form the first forming part 11, and the middle part of the moving mold 2 is protruded outward to form the second forming part 24. The moving mold 2 moves horizontally to close with the fixed mold 1, and the protruding part of the moving mold 2 is embedded in the recessed part of the fixed mold 1. When the moving mold 2 and the fixed mold 1 are fully engaged, the space between the first forming part 11 and the second forming part 24 forms a forming cavity for pressing and forming the velour material and fiberglass board material of the car tailgate lower trim panel.

[0046] The first forming part 11 has three first hanging pins 12 spaced apart above it, and the second forming part 24 has three first storage holes 23 spaced apart above it, which are suitable for inserting the first hanging pins 12. The second forming part 24 has three second hanging pins 22 spaced apart above it, and the first forming part 11 has three second storage holes 13 spaced apart above it, which are suitable for inserting the second hanging pins 22.

Finally, the molten plastic is injected into the injection molding device 3, and the twenty-four solenoid valves 32 are controlled to open the corresponding injection tubes 33 in sequence according to the set timing, so that the molten plastic is injected into the molding tank 21 and cooled and formed on the fiberglass board material, thus completing the injection molding.

[0050] In this embodiment, the fiberglass board material and the velvet material are pressed and formed by the first molding part 11 and the second molding part 24 before injection molding to form the main body of the lower trim panel of the car tailgate. Then, the material is injected into the molding groove 21, and the reinforcing ribs and snap-fit ​​structure are directly injection molded on the fiberglass board. The pressing is completed by the closing of the moving mold 2 and the fixed mold 1, and then injection molding is performed. This optimizes the process of covering the velvet surface after injection molding. At the same time, only the reinforcing ribs and snap-fit ​​structure need to be injection molded on the fiberglass board, which further reduces the time and material consumption required for production and improves production efficiency. In addition, the use of fiberglass board as the main material of the lower trim panel of the car tailgate achieves lightweighting and improves the noise reduction effect.
