AI Technical Summary
The existing injection mold has a reduced clearance between the upper and lower molds after preheating, which can cause it to jam and prevent it from opening, affecting the use and lifespan of the mold.
The structure adopts a drive component, connector, and insert plate design. The drive component drives the connector and insert plate to insert or withdraw, avoiding complete mold closing between the upper and lower molds. The cylinder is used as the drive component to ensure reliability and flexibility.
This avoids jamming between the upper and lower molds, protects the mold from damage, ensures normal use, reduces mold maintenance costs, and improves reliability.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of injection molds, and in particular to an injection mold for automobile accessories. Background Art
[0002] The injection molds currently used on the market for injection molding hemp fiber cloth and plastic particles into automotive accessories first need to be preheated to a predetermined temperature before operation. When the injection mold is preheated to the predetermined temperature, the injection mold can realize injection molding of the hemp fiber cloth and plastic particles into automotive accessories. Since the injection mold needs to be preheated to a predetermined temperature during use, and the material used to manufacture the injection mold will have a certain amount of expansion after preheating, in order to ensure that the upper mold and the lower mold in the injection mold have a suitable fitting clearance after preheating, the fitting clearance between the upper mold and the lower mold will be reduced during the design of the injection mold. Since the fitting clearance between the upper mold and the lower mold is reduced during the design of the injection mold, when the injection mold is stopped and the temperature of the injection mold is reduced to room temperature, and when the upper mold and the lower mold are in the closed mold state, the fitting clearance of the injection mold is small, resulting in the upper mold and the lower mold being stuck and unable to open the mold, which will cause damage to the injection mold or affect the normal use of the injection mold. Summary of the Invention

The automobile trim injection mold also includes a plurality of driving members, connecting members arranged in a one-to-one correspondence with the plurality of driving members, and insert plates arranged in a one-to-one correspondence with the plurality of driving members. The plurality of driving members are distributed circumferentially and are all fixed to the bottom of the lower mold. One end of each connecting member is fixed to the driving end of the driving member at the corresponding position, and each insert plate is fixed to the other end of the connecting member at the corresponding position. Each driving member is used to drive the connecting member at the corresponding position to move so that the connecting member drives the insert plate at the corresponding position to be inserted into the gap between the upper mold and the lower mold or to be pulled out from the gap between the upper mold and the lower mold.
[0005] By adopting the above-mentioned structure, after the present invention is used, each driving member can drive the connecting member at the corresponding position to move so that the connecting member drives the plug plate at the corresponding position to be inserted into the gap between the upper mold and the lower mold, thereby avoiding the upper mold and the lower mold from being in a completely closed state, and then avoiding the situation where the upper mold and the lower mold are stuck and cannot be opened, that is, avoiding damage to the injection mold or affecting the normal use of the injection mold.
