Mold closing device for injection molding machine and mold closing method of mold closing device

Abstract

The invention discloses a mold closing device for an injection molding machine. The mold closing device comprises a bottom frame, a fixed seat, a clamping mechanism, a sliding seat, sliding rods, a push seat, a buffer connecting seat and a mounting seat, wherein the fixed seat is installed at one end of the top of the bottom frame, the mounting seat is installed at the other end of the top of thebottom frame, the sliding rods are installed on the periphery between the fixed seat and the mounting seat, and the sliding seat and the buffer connecting seat are installed on the outer sides of thesliding rods in a sliding mode. According to the mold closing device for the injection molding machine, when a mold is placed on a fixed limiting block and the bottom of the mold makes contact with afixed plate, an induction block is completely compressed into a containing groove at the moment, a second spring is compressed into a telescopic groove, a movable contact at the bottom of a second limiting sliding block makes contact with a fixed contact at the top of a supporting rod at the moment, and electric connection between a storage battery and a PLC is kept; and then a hydraulic pump is controlled by the PLC to clamp the mold, it is guaranteed that the bottom side of the mold makes contact with the fixed seat and the sliding seat, and it is guaranteed that subsequently-produced injection molding parts meet the production standard.

Description

technical field [0001] The invention relates to the field of mold clamping equipment for injection molding machines, in particular to a mold clamping device for injection molding machines and a mold clamping method thereof. Background technique [0002] The mold clamping device of the injection machine is mainly composed of a fixed template, a movable template, a tie rod, an oil cylinder, a connecting rod, a mold adjustment mechanism, and a product ejection mechanism; the mold clamping device is a system that ensures reliable locking and opening of the molding mold, and takes out the product . [0003] According to the mold clamping device for injection molding machine, the mold and the mold clamping device need to be assembled first, but when producing different injection molded parts through the injection molding machine, the mold needs to be replaced. The existing mold replacement method is complicated and inconvenient to operate. Seriously affect the production efficien...
