CN223520113U - Multi-station punching injection molding nozzle device - Google Patents

Abstract

A multi-station punching device for injection molding gates includes two symmetrically arranged clamping frames on a processing table, which are slidably connected to the processing table. Multiple clamping seats for limiting mold positioning are symmetrically arranged on the clamping frames. Two fixed frames are symmetrically arranged on both sides of the processing table, and rotating shafts are rotatably mounted on the fixed frames. The two rotating shafts have identical structures. Activating a second motor causes a disc to rotate, allowing a column to slide from one end of an arc-shaped groove to the other. During this process, the two 16s gradually close at the top of the workpiece, thereby cutting the injection gate position on the mold. This facilitates the simultaneous removal of gates from multiple molds, improving mold processing efficiency.
