Abstract

Disclosed is an injection molding process cooling liquid. The injection molding process cooling liquid is composed of raw materials including, by weight part, 10-20 parts of butanol polyoxyethylene ether, 8-12 parts of sodium nitrate, 1-3 parts of borax, 10-12 parts of stearic acid, 9-13 parts of organic silicone oil, 11-15 parts of phosphoric acid and 6-12 parts of potassium hydroxide. The injection molding process cooling liquid has the advantages of being good in cooling effects, high in bacteriostatic effects and long in service life; the raw materials for preparing the injection molding process cooling liquid are easy to acquire and environmentally friendly; a preparation method of the injection molding process cooling liquid is simple and applicable to other machining fields.

Description

technical field [0001] The invention belongs to the field of plastic injection molding, and in particular relates to a cooling liquid used in the injection molding process. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is achieved through injection molding machines and molds. [0003] In injection molding molds, the design of the cooling system is very important. This is because the molded plastic product can only be cooled and solidified to a certain rigidity, and the deformation of th...
