Embodiment 1

[0041] see figure 1 , a new type of high-efficiency heat dissipation injection mold, including an upper mold 11 and a lower mold 12 that match each other, and one end of the upper mold 11 and the lower mold 12 close to each other forms a mold cavity 22, and an injection port 21 is dug in the middle of the upper end of the upper mold 11, and the injection port 21 communicates with the mold cavity 22. The upper mold 11 is inlaid with a plurality of evenly distributed external conduction expansion mechanisms. The lower mold 12 is equipped with a heat collection external conduction mechanism. The heat collection external conduction mechanism includes condensation channels and a plurality of heat conduction rods 4. One end of the heat conducting rod 4 is flush with the upper surface of the lower mold 12 , and the other ends of the plurality of heat conducting rods 4 all extend into the inside of the condensation channel and contact each other.

Abstract

The invention discloses a novel high-efficiency heat dissipation injection mold, and belongs to the field of injection molding. The novel high-efficiency heat dissipation injection mold comprises an upper mold and a lower mold which match each other, the ends, close to each other, of the upper mold and the lower mold form a mold cavity, and an injection molding port is dug in the middle of the upper end of the upper mold. Through arrangement of an outer guide expansion mechanism and a heat collection outer guide mechanism, in one aspect, during injection molding, heat in melt may be transferred to the outside along the outer guide expansion mechanism, an embedded layer is heated to expand, meanwhile, an epitaxial heat conduction needle is extended out of the upper mold, so that a contact area with the outside can be effectively increased, and outer heat dissipation can be significantly accelerated; and on the other hand, the heat of the melt is collected to the heat collection outer guide mechanism along a heat conduction rod, heat is dissipated to the outside through a condensation channel, so that dissipation of the heat carried in the melt can be effectively accelerated, coolingtime of the melt can be significantly shortened through double heat dissipation, cooling and shaping of a finished product is further accelerated, and then the working efficiency of a whole injectionmolding process can be effectively improved.

Description

technical field [0001] The invention relates to the field of injection molds, and more specifically, relates to a novel high-efficiency heat dissipation injection mold. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) 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. Injection molding is mainly divided into the following three categories: [0003] 1. Rubber injection molding: Rubber injection molding is a production method in which rubber is injected directly from the barrel into t...
