AI Technical Summary
Technical Problem
Existing EPS foam molds suffer from adhesion and insufficient cooling time during demolding, resulting in low demolding efficiency and a lack of dual demolding mechanisms.
Method used
A rapid demolding mechanism for EPS foam molds was designed, which uses a pushing and blowing method for secondary demolding, and uses a flow guiding blowing method to assist demolding, combined with anti-blocking components to prevent channel blockage.
Benefits of technology
It improves demolding efficiency, reduces the risk of adhesion, increases demolding stability and cooling effect, and reduces the frequency of manual maintenance.

Abstract
This utility model relates to the field of packaging mold technology, specifically a rapid demolding mechanism for EPS foam molds. It includes a mold assembly, a demolding assembly, and an anti-clogging assembly. The mold assembly includes a base, the top of which is bolted to a lower template. The bottom of the lower template contains the demolding assembly. The demolding assembly includes a sliding frame, with ejector pins fixedly arranged at equal intervals on the top of the sliding frame. Each ejector pin has a channel. An air pump is bolted to one side of the base, and an anti-clogging assembly is located at one end of each ejector pin. By adding a dual demolding mechanism, the EPS foam is demolded a second time using pushing and blowing methods. This not only improves demolding efficiency but also assists in cooling, thereby enhancing the performance.
