Injection molding device and process for injection molding of highlight injection molded part with metallic taste by utilizing same

Abstract

The invention discloses an injection molding device and a process for the injection molding of a highlight injection molded part with metallic taste by utilizing the same, wherein a highlight plastic product with the metallic taste can be directly obtained once for all while the injection molding and the secondary processing treatment is not needed. The injection molding device provided by the invention comprises: an injection molding machine mold opening and locking system, an injection molding machine gun barrel internally provided with an injection molding machine screw, a multi-functionalmold temperature machine, a high-pressure gas controller, a terminal controller, a nitrogen generator and a material stoving barrel. The process for the injection molding of the highlight injection molded part with the metallic taste, provided by the invention, comprises the steps of: starting the injection molding machine mold opening and locking system and beginning to close a mold, heating an injection mold, starting the injection molding machine gun barrel to heat resin to ensure that the heated resin reaches to a molten state, inputting nitrogen into the injection molding machine gun barrel, injecting the resin in the molten state into the injection mold to reach the 80-95% of the total weight of a plastic molding product, stopping injecting the resin into the injection mold, coolingthe injection mold till being lower than the softening point the resin per se, opening the mold and taking out to obtain a plastic part with highlight and metallic taste.

Description

[technical field] [0001] The invention relates to an injection molding equipment and a process thereof, in particular to an injection molding equipment and a process for using the equipment to inject metal-sensitive high-gloss injection molded parts. [Background technique] [0002] With the continuous upgrading of economic development, the appearance decoration of products in the industrial industry is emerging one after another. Metallic high-gloss plastic products are one of the products that are increasingly pursuing innovation and change, highlighting individual requirements. [0003] At present, all high-gloss surface plastic products with a metallic feel on the market are obtained through the following methods: 1. Plastic products are obtained by ordinary injection molding processes; [0004] 2. Spray the plastic products with high-gloss oil or baking varnish containing metal powder. [0005] The metal-like high-gloss plastic products obtained by the above-mentioned t...

AI Technical Summary

Problems solved by technology

[0005] The metal-like high-gloss plastic products obtained by the above-mentioned traditional process have the following defects: expensive equipment investment, need to invest in the construction of spraying workshops and spraying lines, resulting in high unit price of finished products, low production capacity, low quality rate, spraying process pollutes the environment, and requires a lot of human resources. For packaging, transportation, repackaging, and retransportation of injection molded products
