Motor-driven thread disengaging mechanism for injection molding

Abstract

The invention discloses a motor-driven thread disengaging mechanism for injection molding. The motor-driven thread disengaging mechanism is characterized in that the motor-driven thread disengaging mechanism comprises a stationary mould, a push plate and a mould base that are arranged from the top down; after grooves in the stationary mould are butted with fractal surfaces on the push plate, a feeding cavity and mould cavities are formed, and the feeding cavity is communicated with the mould cavities; the push plate is connected with the mould base below the push plate through a spring; the motor-driven thread disengaging mechanism further comprises thread mould cores and a transmission shaft that are arranged in the mould base; the upper ends of the thread mould cores penetrate through the push plate and stretch into the mould cavities; a transmission mechanism is arranged between the transmission shaft and the thread mould cores; the transmission shaft can rotate to drive the thread mould cores to rotate; and a rotating mechanism driving the transmission shaft to rotate and a motor driving the rotating mechanism are arranged on the mould base. The motor-driven thread disengaging mechanism has the technical effects of short consumed time and high working efficiency.

Description

technical field [0001] The invention belongs to the technical field of injection molding. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Its use method is to inject the heated and melted material into the cavity of the injection mold under high pressure, and after cooling and solidifying, a molded product is obtained. When the existing injection molded parts need to manufacture screw holes, it is necessary to put a threaded core in the injection mold, and after the injection molding is completed, the threaded injection molded part will come out. [0003] However, since the threaded injection molded part and the threaded core are in a threaded state, to remove the injection molded part after the mold is opened, the threaded core needs to be rotated and withdrawn from the cavity along its thread. At present, the threaded core is unthreaded. The...

Problems solved by technology

[0003] However, since the threaded injection molded part and the threaded core are in a threaded state, to remove the injection molded part after the mold is opened, the threaded core needs to be rotated and withdrawn from the cavity along its thread. At present, the threaded core is unthreaded. The main method is to manually twist the threaded core so that the threaded core withdraws from the threaded part of the injection molded part. This method of thread removal takes a long time, has low work efficiency, and consumes a lot of manpower.
