A washing machine shell injection molding material molding device

Abstract

The invention discloses a washing machine shell injection molding material forming device. The washing machine shell injection molding material forming device comprises a mixing chamber, a pressure control chamber and a mold chamber. The mixing chamber communicates with the mold chamber through a discharging outlet, and a discharging valve is arranged at the end, close to the mold chamber, of the discharging outlet. The mixing chamber is internally provided with a temperature control layer and a stirring chamber body, and the temperature control layer covers the outer wall of the stirring chamber body. A feeding inlet is formed in the top end of the stirring chamber body. A piston is installed between the pressure control chamber and the mold chamber and is connected with the inner wall of the top end of the pressure control chamber through springs. A pressure sensor is installed on the side, making contact with the mold chamber, of the piston. An extrusion rod is installed on one side of the mold chamber, and a mold outlet is formed in the position, corresponding to the extrusion rod, of the other side of the mold chamber. A cooling device is closely installed outside the mold chamber and the extrusion rod. An overflow outlet is formed in the upper side wall of the mold chamber. According to the washing machine shell injection molding material forming device provided by the invention, pressure control is stable, cooling and demolding are high in speed, the forming effect is good, consumed time is short, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to an injection molding material molding device for a shell of a washing machine. Background technique [0002] Among the washing machines sold on the market, most of the shells of washing machines are made of plastic. The main plastic molding process includes mixing plastic raw materials, injecting them into molds, performing pressure maintaining, cooling operations, and finally demoulding. The process of each step will affect the effect of molding, especially the process of cooling and demoulding. [0003] During the cooling process, the cooling speed of the existing molding device is slow and the cooling time is not enough, which will affect the effect of material molding. Slow cooling speed will lead to long molding time, and insufficient cooling time and temperature will make the molding effect of the material in the mold poor. . Product deformation often occurs duri...

AI Technical Summary

Problems solved by technology

[0003] During the cooling process, the cooling speed of the existing molding device is slow and the cooling time is not enough, which will affect the effect of material molding. Slow cooling speed will lead to long molding time, and insufficient cooling time and temperature will make the molding effect of the material in the mold poor.

Product deformation often occurs during demoulding, which affects product quality

The existing molding device is difficult to demould, takes a long time, and delays the production efficiency of the product

[0004] In addition, the pressure control of the existing injection molding device for the shell of the washing machine is unstable during the pressure holding process. As the temperature of the material changes, the pressure in the mold will also change. Just give the same pressure as the material in the mold. It will make the pressure holding effect not good and affect the molding effect of the product
