Abstract

The invention discloses an injection mold for a motor wind wheel. The injection mold comprises an outer box, a box cover and an injection molding port, wherein the injection molding port is connectedwith an injection molding cavity in a sealing mode, a mold cavity is formed in the outer box, a mold cavity sleeve is connected to the outer side of the mold cavity in a sealing mode, the outer box isprovided with a cooling cavity located at the outer side of the mold cavity sleeve, a cooling sleeve is connected to the outer side of the cooling cavity in a sealing mode, magnetizing liquid is contained in the cooling sleeve, a permanent magnet is fixedly connected to the outer portion of the bottom of the cooling sleeve, and the mold cavity sleeve and the cooling sleeve are jointly connected with a transmission structure. The injection mold has the advantages that according to a magnetothermal effect, an injection molding product is cooled through the demagnetization heat absorption actionof a ferromagnetic substance in the injection molding process, and the effect of uniform forming is achieved through the mold cavity sleeve and the cooling sleeve which rotate in opposite directions,so that injection molding quality is improved, and the injection mold is convenient to use.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for a motor wind wheel. Background technique [0002] Injection molding is a method of producing and modeling industrial products. It is divided into injection molding molding method and die-casting method. Injection molding machine (referred to as injection machine or injection molding machine) is to make thermoplastic or thermosetting materials into various shapes by using plastic molding molds. The main molding equipment for plastic products, injection molding is achieved through injection molding machines and molds. [0003] The motor wind wheel is generally processed by injection molding technology, and the hot raw material is put into the mold through an external injection gun or injection molding machine. However, the injection mold in the prior art adopts a natural cooling method during molding, which makes the processing efficiency poor. Moreov...
