Abstract

The auxiliary limiting stopper comprises a positioning bolt, a supporting piece, a fastening bolt, a fastening block and a fastening plate, the supporting piece is horizontally arranged, one end of the supporting piece is rotatably connected to a threaded rod of the positioning bolt, and the other end of the supporting piece is in threaded connection to a threaded rod of the fastening bolt; the fastening block is installed at the bottom end of a screw rod of the fastening bolt and presses the top face of the fastening plate downwards. The position of the limiting stopper is fixed through the positioning bolt, the fastening block is driven to move up and down through cooperation between the supporting piece and the fastening bolt, then under isolation of the fastening plate with the proper size, the acting pressure of the end is dispersed, and therefore the workpiece is effectively prevented from being damaged by clamping while the clamping effect is guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of clamps, in particular to the technical field of an auxiliary limiter for a clamp. 【Background technique】 [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. It is divided into vertical, horizontal and all-electric types. Injection molding is to plasticize the plastic in the heating barrel of the injection molding machine, and then inject it into the cavity of the closed mold by a plunger or a reciprocating screw, thereby forming a plastic processing method of injection molded workpieces with complex shapes, precise dimensions, or inserts. . [0003] At present, when fixtures are used to clamp thin-plate-shaped injection molding workpieces with thin thickness and high processing accuracy requirements, the defo...
