Horizontal rotating mold clamping mechanism of injection molding machine

Abstract

The invention discloses a horizontal rotating mold clamping mechanism of an injection molding machine. The horizontal rotating mold clamping mechanism comprises fixed mold plates, movable mold platesand die locking cylinders. The ends of piston rods of the die locking cylinders are connected with pull rods fixed to the fixed die plates. A rotary platform device is arranged between the fixed die plates and the movable die plates. The rotary platform device comprises a movable platform base arranged at the bottom. Rotary platform rapid movement cylinders for driving the mobile platform base todo back and forth motion along a guide block are arranged at the end, close to the fixed die plates, of the inner side of the guide block in a spaced mode. A rotary disk is rotatably arranged at the upper end of the mobile platform base. A rotary die plate synchronously rotating with the rotary disk is vertically arranged at the upper end of the rotary disk. The center of the lower end of the rotary disk is fixedly provided with a gear. A driving device is arranged at the lower end of one side of the mobile platform base. The driving device comprises a motor arranged vertically. The upper needof the motor is provided with a gear shaft engaged with a gear arranged at the lower end of the rotary disk. Through the horizontal rotating mold clamping mechanism of the injection molding machine,the manufacturing and maintenance cost is effectively reduced, and the injection molding efficiency is improved.

Description

technical field [0001] The invention relates to the field of injection molding machines, more specifically, it relates to a horizontal rotary mold clamping mechanism of an injection molding machine. Background technique [0002] Horizontal rotary injection molding machine is a new multi-component injection molding process scheme in recent years. It is used to realize the joint production of two-color products or two sets of products. It has the following advantages: 1. High production efficiency: no need to pass through multiple machines Collaborate to complete multi-color products, saving translation time of products in multiple machines. Products on both sides of the rotating platform are injection molded at the same time, and two sets of products can also be produced at the same time; 2. Save space; 3. Save the purchase cost of multiple sets of plastic machines, one plastic machine can achieve the effect of two or more sets. [0003] The structural features of the horizo...

Problems solved by technology

[0004] At present, in the field of injection molding machines, the horizontal rotating mold clamping mechanism is mainly realized by three technologies: 1. The rotating mechanism adopts a large turntable bearing. The bearing has high strength and high cost; it is difficult to maintain due to the structural reasons in the later stage; before the rotary action, the platform needs to be supported to avoid the wear of the circumferential surface of the bearing, which will increase the dry cycle of the molding machine and affect the efficiency; 2. The hydrostatic oil film whirl Technology, this technology is transplanted in the machine tool industry, the defects are: high technology, processing, assembly requirements, high price; difficult maintenance; relatively high failure rate; 3, high-pressure liquid or gas jacking rotary technology, this technology is suitable for small horizontal injection molding At present, there are many application manufacturers at home and abroad, mainly using the jacking effect of high-pressure gas or liquid to make the middle rotating platform and the lower fixed moving flat seat detach from the rotation, and there will be no wear between the two

The disadvantage is: it is suitable for small tonnage models (small vertical pressure); due to the jacking action, the dry cycle time of injection molding is prolonged and the efficiency is reduced
