Mold moving and jacking-out system of large injection mold and intermittent production method of large injection molding machine

Abstract

A mold moving and jacking-out system of a large injection mold comprises a support, a horizontal mold moving mechanism, a lifting mechanism and a jacking-out mechanism, wherein the horizontal mold moving mechanism is located over the jacking-out mechanism and supported through the lifting mechanism; the horizontal mold moving mechanism comprises two horizontal moving guide platforms, a mold pulling plate, a mold fixing sliding plate and a driving assembly; the mold pulling plate is connected with the mold fixing sliding plate in a matched mode in the horizontal direction through a pulling hookto drive the mold fixing sliding plate to move in the horizontal direction; the mold is fixed to the mold fixing sliding plate and moves into or out of an injection molding main machine along with movement of the mold fixing sliding plate; the upper end of the lifting mechanism is fixed to the bottom surface of one of the horizontal moving guide platforms to drive the horizontal mold moving mechanism to ascend and descend, and the mold fixing sliding plate and the jacking-out mechanism are made to get close to or away from each other. The mold moving and jacking-out system of the large injection mold can meet the moving and jacking-out requirements of the large injection mold, realize intermittent work of the large injection molding machine, and improve the production efficiency and automation level of the large injection molding machine. The invention further provides an intermittent production method of the large injection molding machine.

Description

technical field [0001] The invention relates to a large-scale injection mold shifting and ejection system, which is used to improve the production efficiency and automation level of a large-scale injection machine, and also relates to an uninterrupted production method of a large-scale injection machine. Background technique [0002] Rubber injection machine is the main equipment for the production of rubber products. It is very mature in the production of small rubber products, but it is rarely used in the production of large products with a clamping force of more than 1000T and an injection volume of more than 20000cc. Because the products produced by large-scale rubber injection machines are relatively large, it takes longer for the products to be inserted into the molding process, vulcanization molding process, and product removal process. The auxiliary production time is too long, which results in the production efficiency of large-scale rubber injection machines. Low, ...

AI Technical Summary

Problems solved by technology

[0007] The key points of the existing scheme are: 1. It is mainly suitable for the production of small rubber products; 2. It can only be adapted to the ejection of single-mould products. During the process of taking products and loading molds, the main machine is in standby mode, and continuous production cannot be realized.

3. The products are relatively small, and cannot meet the production needs of large molds and products in terms of structural stability and positioning accuracy
