Problems solved by technology

In the process of injection molding, some cooled plastic waste will remain in the injection hole and flow channel. Discarding these waste while taking out the plastic product will cause waste, especially some plastics that will cause quality problems when the material is recycled again.

Abstract

The present invention discloses an injection molding mold, which comprises a mold cavity (1), a flow channel (2) and an injection hole (3), a heating device (4) is arranged on the outer side of the flow channel and the injection hole. According to the injection molding mold adopting the technical scheme, the heating device is arranged on the outer side of the flow channel and the injection hole, such that heating can be continuously performed on plastics inside the flow channel and the injection hole during injection molding so as to maintain a melting state of the plastic, such that the cooling waste can be not generated and cost is saved.

Description

technical field [0001] The invention relates to a mold, in particular to an injection mold. Background technique [0002] Injection molds are widely used in the plastic product processing industry. Injection molds are generally adapted for thermoplastic thermoforming. Utilizing the hot-melt principle of thermoplastics, the molten plastic is injected into the cavity of the mold through the injection molding machine, then cooled and shaped, and the mold is opened to take out the plastic product. During the injection molding process, some cooled plastic waste will remain in the injection hole and flow channel. Discarding these waste materials while taking out the plastic product will cause waste, especially some plastics that will cause quality problems when the materials are recycled again. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to address the deficiencies in the prior art and provide an injection mold. When the...
