Mould structure

Abstract

The invention provides a mould structure, which is used for molding a workpiece. The mould structure comprises a fixed mould plate, a movable mould plate, a sliding block, a hot runner system and an inclined ejection assembly, wherein the movable mould plate is installed on the fixed mould, and a mold cavity is enclosed by the movable mould plate and the fixed mould plate; the sliding block is installed on the surface, close to the movable mould plate, of the fixed mould plate; the sliding block is provided with a first flow channel; the hot runner system comprises a hot sprue installed on thesliding block; an outlet of the hot sprue is communicated with the first flow channel; the inclined ejection assembly comprises an inclined ejection head; the inclined ejection head is installed in the mold cavity, is contacted with the side part of the sliding block, and can be used for ejecting the workpiece after a template component is subjected to mold opening; the inclined ejection head isprovided with a second flow channel communicated with the first flow channel and the mold cavity. According to the scheme, the sliding block is provided with the first flow channel, and the inclined ejection head is provided with the second flow channel, so that the communicating distance between an outlet of the hot sprue and the mold cavity is increased, and the pouring distance is further increased; the mould structure enables molten rubber to slowly enter the mold cavity, thus reducing the injection molding pressure and solving the problems that in the prior art, the surfaces of pattern etched surface products molded in the prior art are prone to defects such as gas lines and yin and yang sides.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold structure. Background technique [0002] At present, in the process of molding the air-conditioning panel with the etched surface through the mold, the outlet of the hot runner system is directly connected with the cavity, so that the molten rubber flowing out of the outlet of the hot nozzle of the hot runner system only needs to pass a short distance. It will flow into the cavity, which will cause the molten rubber to rush directly into the cavity, resulting in excessive injection pressure and high temperature. In this way, the molded product will have defects such as air marks and positive and negative surfaces on the outer surface, which will cause Affect the appearance of the molded product. [0003] Therefore, how to propose a mold structure capable of improving the quality of the outer surface of the molded product has become an urgent problem to be solved. Contents of the in...
