Mold applied to production process of automotive interior parts

Abstract

The invention discloses a mold applied to a production process of automotive interior parts. An exhaust hole is arranged on the mold, the exhaust hole is connected with an exhaust pipeline, and the pressure in the exhaust pipeline is smaller than the atmospheric pressure; and the exhaust pipeline is connected with a vacuum pump. The mold disclosed by the invention further has the characteristics of low manufacturing cost, obvious exhaust effect, long service life and the like. After the exhaust structure uses the vacuum pump to exhaust, the blockage phenomenon of an exhaust slot is further relieved, the injection molding pressure can be relatively smooth, an important role is played in stabilizing the quality of injection-molded products and reducing the scrappage of the products and the cost is further reduced.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment used in the production process of automobile interior parts, in particular, relates to a mold used in the production process of automobile interior parts. Background technique [0002] At present, in the technical field of manufacturing equipment used in the production process of automotive interior parts, especially for the production process of automotive plastic parts, molds are very important. In the prior art, molds are mostly composed of upper molds and lower molds. During the production process, through the operation of auxiliary machinery and equipment, according to the shape of the mold, the raw material or wool is arranged between the fixed mold and the movable mold, and then the lifting is manipulated or the upper mold and the lower mold are attached to complete the manufacturing process of the workpiece. But in the prior art, the existing mold has the following technica...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that, using the mold in the prior art, air pockets, small holes or pits often appear on the bonding surface of the workpiece and the upper mold, resulting in unqualified quality of the workpiece, requiring rework of the workpiece, and serious When this happens, the workpiece will be scrapped, the raw materials will be greatly wasted, the manufacturer’s manufacturing cost will be increased, and the production efficiency of automotive interior parts will be seriously affected. However, the mold used in the production process of automotive interior parts
