Design of Exhaust System for Injection Plastic Hanger Mould

Design of Exhaust System for Injection Plastic Hanger Mould:

The exhaust system plays a vital role in ensuring the molding quality of the product.

A. Use the exhaust slot, which is generally located at the last filled part of the cavity. The depth of the exhaust slot varies with different plastics. Basically, it is determined by the maximum allowable gap that the plastic does not produce flash. For example, ABS 0.04 is less than 0.02mm of marl, and the steel is less than 0.02.

B. Use the matching clearance of the core insert push rod or the special exhaust plug to exhaust;

C. Sometimes in order to prevent the vacuum deformation of the product when it is ejected, a gas pin must be installed;

D. Sometimes in order to prevent the vacuum adsorption of products and molds, anti-vacuum adsorption components are designed
