AI Technical Summary

Technical Problem

Existing foam box forming molds are prone to clogging during the feeding process of EPS pellets, which increases feeding time and affects the quality of the finished product.

Method used

A foam box rapid forming mold including a base frame, a lower mold assembly and an upper mold assembly is adopted. The upper mold assembly and the lower mold assembly are clamped through a hydraulic telescopic cylinder to form a box-shaped molding cavity, and a steam supply mechanism and feeding assembly are provided in the lower mold assembly, including a sliding rotating part, a spiral feeding part and a sealing part to ensure that the EPS particles enter the molding cavity evenly and quickly.

Benefits of technology

The rapid and even feeding of EPS particles is achieved, and the forming efficiency and finished product quality of the foam box are improved. Through the action of thimble and gas, the foam box is automatically discharged, further improving the forming efficiency.

Abstract

The invention discloses a foam box rapid prototyping mold, which relates to the field of foam molding technology, and comprises a base frame and a lower mold assembly and an upper mold assembly mounted on the base frame; the upper mold assembly is mounted on the base frame directly above the lower mold assembly through a hydraulic telescopic cylinder, the lower mold assembly is fixedly mounted on the base frame, and when the upper mold assembly and the lower mold assembly are molded together, a box-shaped molding cavity is formed between the upper mold assembly and the lower mold assembly, and the lower mold assembly is connected with a steam supply mechanism for introducing steam into the molding cavity; the lower mold assembly comprises a lower mold plate fixedly mounted on the base frame and a concave mold fixedly mounted on the top of the lower mold plate. The invention can quickly and evenly deliver pre-foamed raw material particles into the molding cavity, which not only improves the molding efficiency of the foam box, but also improves the quality of the finished foam box product. In addition, after the foam box is molded, the foam box can be automatically discharged from the concave mold under the action of the ejector pin and the gas, which further improves the molding efficiency of the foam box.
