Guide rod embracing claw mold locking regulating device for two-template injection molding machine

Abstract

The invention relates to a guide rod embracing claw mold locking regulating device for a two-template injection molding machine, which comprises a fixed template and a movable template arranged on an injection molding machine frame, wherein a half mold is respectively arranged on the fixed template and the movable template, a pressure boosting plate is arranged in the movable template, the fixed template and the movable template are connected through guide rods, the number of the guide rods is four, each guide rod is provided with a locking mechanism, each locking mechanism comprises tooth rings arranged on the guide rods, through holes are arranged in the movable template, the guide rods with the tooth rings movably pass through the through holes, an open and close type embracing claw is arranged on the outer side wall of the movable template, and embracing teeth are arranged on the embracing claw and are mutually engaged with the tooth rings. The guide rod embracing claw mold locking regulating device is characterized in that a regulation rod is arranged on the movable template, the regulation rod passes through the embracing claw, the head of the regulation rod is provided with a position limiting mechanism, and a compression spring is arranged outside the regulation rod arranged between the movable template and the embracing claw. The scheme has the advantages that molds can be locked without gaps, an injection molding product has good quality, and the production efficiency is high.

Description

technical field [0001] The invention relates to an injection molding machine, in particular to a mold locking adjustment device for a guide rod of a two-platen injection molding machine, which belongs to the field of plastic machinery. Background technique [0002] The main structure of the two-platen injection molding machine includes the injection device installed on the frame, the movable platen and the fixed platen, and the opening and closing mechanism and the clamping mechanism. The mold is installed in the movable platen and the fixed platen. There are many specific technical solutions for the clamping mechanism, one of which includes a guide rod with inverted teeth (gear rings), a through hole in the movable template or fixed template, and a gear ring The guide rod moves through the through hole, and the grip (holding device) is installed on the outer wall of the movable template or the fixed template. The grip is shaped on the grip teeth, and the grip teeth cooperat...

Problems solved by technology

However, in actual use, the holding teeth on the grip sometimes bite on the tooth tips between the two gear rings, and the adjacent tooth tips of the tooth rings on the guide rod are at least 5mm above. When the tip is on, under the tension of the mold, the grip cannot bite the tip of the tooth, and a gear ring will be retracted outward, resulting in a gap of at least 5mm between the two molds, and the product cannot be injection molded.
