Plastic injection moulding mold for cooling and demoulding conveniently

Abstract

The invention discloses a plastic injection moulding mold for cooling and demoulding conveniently. The plastic injection moulding mold comprises a lower mold, a second top cap, a separation plate andan air vent, a first guide post and a second guide post are fixed at the top end of the lower mold, the second top cap is installed at the top end of the second guide post, the separation plate is fixed in a bottom groove, a control magnet is fixed at the top end of a center shaft, vertical plates are fixed at the top ends of a first inner magnet and a second inner magnet, a function spring is installed on the vertical plate, the function spring and the inner wall of a top groove are mutually connected, and the air vent and a cooling pipe are mutually connected. The plastic injection mouldingmold for cooling and demoulding conveniently improves the structure of the traditional plastic injection moulding mold by adopting the novel structure design, so that the device still can rapidly coola plastic product not cooled in the mold after the injection moulding is finished, the product finishing injection moulding is rapidly separated from the mold, the mold can be injection-moulded againconveniently, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic products, 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. Since plastics can be made into a variety of products with different hardness or structure by means of blow molding and injection molding, most of these products have stable properties and light weight. , and easy to use, so plastic products are loved by consumers. [0003] As the frequency of people using plastic products in production and life continues to increase, the plastic manufacturing industry is also developing rapidly. When using injection molding to manufacture plastic products, it is found that the traditional plastic injection molds have unreasonable structural design. After the injection molding is completed, The plastic in the mold cannot be cooled quickly, which lead...
