Abstract

The invention relates to the technical field of automobile parts, and discloses a mold capable of automatically demolding used for automobile parts. The mold comprises a module, a semiconductor chilling plate is fixedly connected to the top of the inner wall of the module, a piezoresistor is fixedly connected to the inner wall of the module, a movable cavity is fixedly connected to the top of the inner wall of the module, the bottom of the inner wall of the movable cavity is fixedly connected with a first spring, and the top of the first spring is fixedly connected with a push block which penetrates through the movable cavity and the module and extends to a position above the module. According to the mold capable of capable of automatically demolding used for the automobile parts, molten materials are injected to the surface of a mold piece, heat is transmitted to the semiconductor chilling plate to generate current, the current electrifies an electromagnet I and an electromagnet II, the electromagnet I drives a push block to store force downwards, the electromagnet II pushes a dielectric plate II downwards, the relative area between a positive plate and a negative plate is changed to generate current, and electrifying is carried out on a conductive point through the piezoresistor, so that the electrorheological fluid is changed into solid from liquid, and the effect of fixing the push block is achieved.

Description

technical field

[0001] The invention relates to the technical field of auto parts, in particular to an automatic demoulding mold for auto parts. Background technique

[0002] In recent years, with the improvement of people's living standards, the number of automobile purchases in the society has shown an explosive blowout. In response, the automobile manufacturing industry and its upstream and downstream industries have developed rapidly, and a large number of automobile manufacturing companies have emerged. Among them As an indispensable production process in automobile production, injection molding process can be said to be related to the production speed of products.

[0003] At present, the injection molding equipment on the market has more or less defects, usually there is a problem that it cannot be molded at one time or the product is not easy to take out after molding, so generally in the injection molding process, because the product cannot be molded at one time, th...
