AI Technical Summary

Technical Problem

During the water cooling process, existing injection molds affect the heat exchange effect due to scale attached to the surface of the heat sink. At the same time, the mold cavity temperature is low during injection molding, resulting in the solidification of raw materials. Insulation usually requires heating of electrical components, which consumes more energy.

Method used

A multi-mold cavity injection mold is designed, using a technology that combines heat conduction sheet and heat storage block. The heat conduction sheet comes into contact with the water source when water is cooled, and heat is transferred to the insulation material in the heat storage block through the heat absorbing sheet for preheating the mold cavity. At the same time, the scale on the heat conduction sheet is removed by flipped heat storage parts.

Benefits of technology

It effectively improves the heat exchange effect and insulation performance of the mold cavity, reduces energy consumption, avoids raw material solidification, and extends the service life of the mold.

Abstract

The invention discloses a multi-mold-cavity injection mold, and belongs to the technical field of injection molds, the multi-mold-cavity injection mold comprises a lower mold, the upper end of the lower mold is covered with an upper mold, a plurality of female mold cavities are formed in the lower mold, and the lower end of the upper mold is fixedly connected with male molds matched with the female mold cavities; the lower end of the female die cavity in the lower die is fixedly connected with a heat conducting piece, the heat conducting piece is located on the inner side of a containing groove, the containing groove is formed in the lower die, a water inlet pipe is installed on the right side of the containing groove, a water drainage pipe is installed on the left side of the containing groove, and an overturning heat storage part is installed in the containing groove. According to the injection mold with the multiple mold cavities, when the mold cavities are cooled, heat dissipated by the mold cavities can be absorbed and stored through the heat storage materials, the stored heat is used for conducting heat preservation and preheating on the mold cavities in the next injection molding process, energy loss is reduced, meanwhile, in the water cooling process, water scale attached to the surfaces of cooling fins can be scraped away, and the heat dissipation efficiency is improved. And the subsequent heat exchange effect is improved.
