1、Horn-molded automobile door plank injection mold with exhaust structure CN 203236654 U摘要The utility model discloses a horn-molded automobile door plank injection mold with an exhaust structure. The injection mold comprises a movable mold, a fixed mold, a movable mold horn embedding block and a

2、fixed mold horn embedding block, wherein the movable mold horn embedding block is fixedly connected with the movable mold; the fixed mold horn embedding block is fixedly connected with the fixed mold; the movable mold horn embedding block comprises a plurality of embedding block components; and exha

3、ust grooves communicated with a molding cavity are formed in the side surfaces of the embedding block components. According to the injection mold, an exhaust passage is formed by the molding cavity of the movable mold horn embedding block and fixed screw holes from the exhaust grooves to the movable

4、 mold, so that when the injection molding is carried out, the air in the complicated molding cavity trapped at a horn mesh can be exhausted out of the injection mold. Thus, injection molding materials are filled sufficiently. Therefore, the surface quality of automobile door planks is improved, and

5、further, the percent of pass of the automobile door planks is improved; and the subsequent machining process of the automobile door planks is reduced. As a result, the production efficiency is improved.说明  A car with a horn shaped door type injection mold ventingTechnical Field0001 The inv
