Universal mold change trolley system

Abstract

The invention discloses a universal mold change trolley system which comprises a transverse slide rail, a plurality of injection molding machines and a mold change trolley. The injection molding machines are arranged on two sides of the transverse slide rail. The mold change trolley comprises a jacking bottom plate and a mold change platform; the jacking bottom plate is fixed to the top of chassis by the aid of a plurality of lifting columns; at least one hydraulic locking fixture is arranged in each injection molding machine; each hydraulic locking fixture comprises a support shaft, a compression plate, a first groove, a steel ball, a first spring, a second groove, an oil cylinder barrel, a piston and a second spring; oil inlets and outlets are formed in the bottoms of the second grooves; one end of the bottom of each compression plate can be in contact with the corresponding steel ball in rotation procedures, and the other end of each compression plate can be in contact with an extending end of a T-shaped handle of the corresponding piston. The universal mold change trolley system with the structure has the advantages that molds can be automatically and quickly changed, the problems of unsafe characters and long change time when existing molds are changed can be solved, and workload on workers can be relieved; the universal mold change trolley system is high in universality, and the molds can be pertinently changed for different models of injection molding machines; the molds can be accurately clamped, and the universal mold change trolley system is high in positioning precision.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a universal mold changing trolley system. Background technique [0002] In the current plastics industry, when a large injection molding machine needs to replace the mold, it can only be replaced by a crane and manpower. When the crane replaces the mould, it is prone to illegal operations such as crooked pulling and slanting, and the wire rope is also prone to damage the machine tool equipment during the pulling process. On the other hand, because the pulling distance is difficult to control, the operator operates completely by his own feeling, which is very easy to cause the accident that the mold slips off the ground and hurts people due to improper force. In addition, moving large molds manually is time-consuming and labor-intensive. [0003] The Chinese utility model patent application with the application number 201420793794.7, the title of the invention...

AI Technical Summary

Problems solved by technology

[0010] However, there are still technical problems as follows: for large injection molding machines of different tonnages and different models, the heights are not the same, and one mold changing trolley can only be used for one type of injection molding machine, which has poor versatility

In addition, the positioning accuracy is low and it is easy to misjudge
