AI Technical Summary
Existing injection molds are difficult to use for one-time molding and precise positioning of transparent parts and pen-shaped shells, and demolding is difficult, resulting in low production efficiency and high costs.
Design a mold structure including a front mold assembly, a rear mold assembly, a gating system, and a sliding mechanism. Through the cooperation of the insert and the pull rod, the transparent part can be stably positioned and molded in the injection cavity in one step, and the wedge mechanism can be used for easy demolding.
This enables one-time injection molding of transparent parts and pen-shaped shells, improving production efficiency, reducing costs, and ensuring product quality and mold lifespan.
