Turntable pipe damage prevention structure for multi-component injection molding machine

Abstract

The invention discloses a turntable pipe damage prevention structure for a multi-component injection molding machine. The turntable pipe damage prevention structure for the multi-component injection molding machine comprises a movable mold plate and a turntable device rotationally arranged on the movable mold plate, wherein a rotating device is arranged between the movable mold plate and the turntable device and comprises a fixed plate, a rotating shaft, a pipe divider and a turntable pipe; the fixed plate is arranged on a core shaft of the turntable device; the rotating shaft is arranged on the fixed plate; the pipe divider is arranged on the rotating shaft; one end of the turntable pipe is in matched connection with the fixed plate, the middle of the turntable pipe is arranged on the pipe divider, and the other end of the turntable pipe is arranged on the turntable device; and a rotating joint is further arranged on the rotating table pipe, and the turntable pipe can freely rotate through the rotating joint. Through the improvement of the structure, the turntable pipe damage prevention structure for the multi-component injection molding machine has the characteristics of simple and reasonable structure, excellent performance, quick disassembly and assembly, convenient use, short pipe replacement time, simple daily maintenance, low manufacturing cost, long service life, safety, reliability, simple and attractive appearance and high practicability.

Description

technical field [0001] The invention relates to an anti-damage structure for a turntable pipe used in a multi-component injection molding machine. Background technique [0002] Multi-component injection molding machines generally have two sets of molds, and the two sets of molds change the position of the molds through the rotation of the turntable, so as to realize the in-mold combination of various plastics; because the mold needs to rotate, the water and oil circuits must rotate with the mold. Currently common solutions are: [0003] 1. Put the water pipe and the oil pipe together through the middle of the turntable mandrel, and then connect them to the mold: this solution will cause the pipes to be easily entangled or knotted, causing the pipes to break. [0004] 2. Use a turntable to distribute the mandrel group, and then use a tube to connect to the mold: This scheme has a complicated mechanism, high processing costs, complicated maintenance, and high maintenance cost...
