High-precision production injection molding process and injection molding machine

Abstract

The invention belongs to the technical field of data joint injection production, and aims to provide a high-precision production injection molding process and an injection molding machine. According to the technical scheme, the injection molding machine comprises a rack, wherein a workbench is arranged on the rack; a first oil cylinder is arranged at the lower end of the rack; a driving plate is slidably connected to the output end of the first oil cylinder; a driving rod is fixedly connected to the upper end of the driving plate; the upper end of the driving rod is fixedly connected with a fixing plate; the upper end of the workbench is provided with a lower die; the lower end of the fixing plate is provided with an upper die; the upper end of the fixing plate is fixedly connected with aguiding column; one side of the rack is provided with an extension platform; a feeding mechanism is arranged on the extension platform; and a cooling circulation system is arranged in the lower die and the upper die. According to the high-precision production injection molding process and the injection molding machine, the cooling circulation system is additionally arranged to the injection molding machine, so that a molten plastic in a die cavity is cooled by the cooling circulation system after the molten plastic is injected into the die cavity, the cooling effect is good, the molding speedis high, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding production of data joints, in particular to a high-precision production injection molding process and an injection molding machine. Background technique [0002] With the continuous improvement of the international status of my country's manufacturing industry, the mold industry has achieved rapid development, the demand for molds has also doubled, and its production cycle is getting shorter and shorter. For the diversification of varieties, the diversification of production process and the complexity of production capacity. Injection molds are generally suitable for thermal molding of thermoplastics. Using the principle of hot melting of thermoplastics, the molten plastic is injected into the cavity of the mold through an injection molding machine, then cooled and shaped, and the mold is opened to take out the plastic product.

AI Technical Summary

Problems solved by technology

[0004] After the existing injection molding machine injects the molten plastic into the mold cavity, it only cools the high-temperature molten plastic through the temperature of the mold itself, but the cooling time is often longer, and the cooling effect is not very good, so it will prolong The entire injection molding process reduces work efficiency
