Multi-insert quick installing and placing clamp for push type injection molding plastic part

Abstract

The invention is suitable for multi-insert quick installation and placement for a multi-cavity structure injection mould with multiple cavities arranged in an in-line balance manner. The multi-insert quick installing and placing clamp is located by using a guide pillar of a plastic injection mould, and inserts are placed in insert clamping holes outside the mould. Upper clamping plates and lower clamping plates of the inserts are guided to slide in a sliding way, and the inserts are loosened or clamped by using a manual loosening mechanism and an automatic spring resetting mechanism. When the multi-insert quick installing and placing clamp works, the inserts are placed in the insert clamping holes outside the mould by an operator, the clamp is located on the guide pillar of the mould; after the inserts arrive at preset positions in the mould, the upper clamping plates and the lower clamping plates of the inserts loosen the inserts under the action of the manual loosening mechanism to complete that the inserts are automatically placed. After the inserts are installed and placed, the upper clamping plates and the lower clamping plates of the inserts reset under the action of elastic force. The multi-insert quick installing and placing clamp is simple in structure and low in cost due to no limit to types of injectors; the defects of low installing efficiency, poor safety and high production cost in an insert manual mould are overcome, the work efficiency is increased, and the processing cost is lowered.

Description

Technical field: [0001] The invention relates to the field of injection molding of plastic parts of injection machines, and relates to a clamp for quickly placing multiple inserts of injection molding plastic parts of a pushing type. Background technique: [0002] During the injection molding process of plastic parts, the placement of the inserts in the plastic molding mold takes a lot of time, especially in the production of small plastic parts with multiple cavities in one mold, the placement time of the inserts will be longer, resulting in empty injection equipment. The running time is too long, the production cost of plastic parts will increase, and the waste of manpower, equipment and energy will be lost. In addition, when there are many inserts to be placed, the operating time of the operator's limbs in the plastic molding mold is longer, and the probability of personal safety accidents is greatly increased. Especially for horizontal injection machines, the labor inten...

AI Technical Summary

Problems solved by technology

[0003] The present invention is designed in combination with the rapid placement of multiple inserts in an injection mold with a side-by-side multi-cavity structure, which overcomes the problems of long occupation time, high labor intensity for the operator, and poor safety caused by the separate installation of single inserts in the mold, and improves the efficiency of the injection molding machine. The production efficiency of injection molding of plastic parts is easy to operate
