Low-loss type injection mold

Abstract

The invention discloses a low-loss type injection mold, and belongs to the technical field of molds. Heat storage bags for collecting waste heat are arranged at four corners of the bottom end of a mold core, the heat storage bags are connected with the mold core through heat insulation rods, upper heat conductors and lower heat conductors which extend into a conduction seat and the heat storage bags respectively are mounted in the heat insulation rods, and before water cooling forming, by means of the magnetic attraction effect, the lower heat conductor penetrates through a heat insulation plate to be connected with the upper heat conductor, heat is conducted through the upper heat conductor and the lower heat conductor and stored in the heat storage bags, heat recovery is achieved, preliminary cooling of the mold core is achieved, water cooling operation of a plurality of water cooling pipes is matched, the cooling effect on the mold core is further improved, cooling forming of a product is realized, and in the water cooling process, the lower heat conductor and the upper heat conductor are disconnected, heat in the heat storage bags cannot be lost due to water cooling of the mold core, the heat stored in the heat storage bags can be used for preheating during next pouring, and energy conservation and low loss are achieved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a low-loss injection mold. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. [0003] Injection molds are the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes using plastic molding molds. Injection mold is a tool to give plastic products a complete structure and precise size. During the injection molding process, the temperature control is very good, including p...

Problems solved by technology

[0004] However, the existing injection mold consumes a lot of energy, which is mainly reflected in the heating aspect. Since the temperature control needs to be very precise, it needs to be heated by heating equipment when heating, and cooled by cooling equipment when cooling down, which often leads to wasteful loss of heat. Larger, when the next injection is made, it needs to be reheated and preheated, so it is difficult to achieve energy saving and low loss
