Problems solved by technology

[0005] When this solution is used for injection molding, the raw materials in the hot-melt state contact the mold with a lower temperature, and it is easy to produce a cooling effect on the contact surface first, so that the overall cooling is uneven and cracks appear. At the same time, the cooling effect of the device on the demoulding position Poor, easy to damage the ejection position during ejection

Abstract

The invention relates to the technical field of plastic injection molding, in particular to a plastic injection mold convenient to cool and demold. The plastic injection mold comprises a concave moldand a convex mold matched with the concave mold, wherein a first cooling cavity and a second cooling cavity are respectively arranged in the concave mold and the convex mold; a first branch pipe and asecond branch pipe are fixedly connected to one end, away from a liquid storage tank, of a water outlet pipe; the first branch pipe is fixedly connected and communicated with the concave mold; the second branch pipe is fixedly connected and communicated with the convex mold; pressure stabilizing tanks are arranged on the other side of the concave mold and the other side of the convex mold; a circulating water pump is fixedly connected to the water outlet pipe, heating assemblies are arranged on the first branch pipe and the second branch pipe; and a water pressure demolding assembly is arranged in the convex mold. According to the plastic injection mold, cooling and demolding actions can be conveniently remembered, the cooling is sufficient; the demolding effect is good; the cooling effect is guaranteed for the demolding ejection position, and thus, the damage is reduced; and meanwhile, the mold can be kept at a certain temperature during injection molding, so that uneven injection molding caused by the cold mold is avoided.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to a mold for plastic injection molding which is convenient for cooling and demolding. Background technique [0002] Plastic products are an indispensable product in daily production and life. Plastics can be made into a variety of products with different softness and hardness or different structures by means of blow molding and injection molding. The products made have many advantages and are widely recognized by people. Welcome; Injection molding is a common method for making plastic products. It is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. After the injection molding is completed, it is necessary to carry out the process of cooling and demoulding, so as to remove the finished product...
