Description

Technical Field

[0001] The invention relates to an automobile interior decoration mold, in particular to an automobile interior decoration mold with a rapid cooling function. Background Art

[0002] Automobile interior parts are generally injection molded using a mold. The mold includes an upper mold and a lower mold. A cavity is provided between the upper mold and the lower mold. The molten raw material is injected into the cavity and cooled to form a product. Since the mold mainly plays a molding role, the raw material needs to be cooled quickly after molding so that it can be demolded in a short time, thereby improving the utilization efficiency of the mold. However, existing molds generally do not have a rapid cooling function, which reduces the demolding efficiency. Therefore, it is necessary to design an automobile interior mold with a rapid cooling function to solve the above problem. Summary of the invention

[0003] According to the above technical problems, the present invention provides an automobile interior mold with a rapid cooling function, comprising an upper mold and a lower mold, wherein limit blocks are symmetrically arranged on both sides of the upper mold, a slider is arranged on the upper side of the limit block, a sealing plate is arranged on the outside of the upper mold, a slide groove is arranged on the inner wall of the sealing plate, and the slider is slidably matched with the slide groove.

[0004] Exhaust holes are provided on both sides of the upper mold, the exhaust holes are connected to the top and side walls of the upper mold, and a vacuum hole is provided on the top of the sealing plate, and the vacuum hole is connected to an external vacuum pump through a vacuum pipe;

[0005] A connecting frame is provided on the top of the sealing plate, one end of the connecting frame is fixedly connected to the top of the sealing plate through a flange, and the other end is connected to an external driving device;

[0006] Grooves are arranged at positions corresponding to the limit blocks on both sides of the lower die, and the grooves cooperate with the limit blocks.

[0007] Furthermore, the limit block is arranged at a position of the upper mold close to the bottom.

[0008] Furthermore, the exhaust hole is an L-shaped structure.

[0009] Furthermore, the sealing plate is a U-shaped structure with the opening facing downward.

[0010] Furthermore, the exhaust hole is located on the upper side of the limiting plate.

[0011] The beneficial effects of the present invention are as follows: the present invention is an automobile interior decoration mold with a rapid cooling function. By setting a sealing plate and a vacuum hole, the raw material in a molten state is injected into the cavity, and the interlayer between the sealing plate and the upper mold is vacuumed by an external vacuum pump, thereby achieving a heat insulation effect, avoiding the situation that the cooling of the raw material is easy to cause the fluidity to decrease and affect the molding quality for some positions that require the raw material to flow a long distance to reach; when demolding after cooling is completed, the sealing plate is lifted up to expose the exhaust hole, destroying the vacuum state in the interlayer, thereby achieving rapid heat dissipation and cooling. The present invention has a rapid cooling function and improves the demolding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
