Mold vibration reduction fixing device of plastic vacuum forming machine

Abstract

The invention discloses a mold vibration reduction fixing device of a plastic vacuum forming machine. The device comprises a frame body, fixed plates, sliding grooves, connecting rods, first sliding blocks, mounting plates, first springs, limiting plates, movable plates, connection rods, rotating shafts, supporting columns, a guide rail, thread push rods, fixed nuts, through holes, second springs,push plates, second sliding blocks, side plates, vertical plates and bolts. The device is reasonable in structure, and easy to operate, through pushing of the two side plates, the two side plates slide in the guide rail through the second sliding blocks, the vertical plates extrude two connection rods through the supporting columns on one ends, one ends of the two connection rods rotate through the rotating shafts, the other ends of the two connection rods are rotatably connected with the movable plates through the rotating shafts, the connection rods push the movable plates to be in slidingconnection with the sliding grooves through the connecting rods and the first sliding blocks, one ends of the movable plates compress the first springs, the first springs provide supporting force forthe movable plates under the effect of the limiting plates, a mold is fixed between the two vertical plates, meanwhile, the mold is subjected to vibration reduction, and mold damage is avoided.

Description

technical field [0001] The invention relates to a fixing device, in particular to a vibration-damping fixing device for a mold of a plastic-absorbing machine, and belongs to the technical field of application of a plastic-absorbing machine. Background technique [0002] Blister molding machine (also called thermoplastic molding machine) is a machine that absorbs heated and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic coils into various shapes of advanced packaging and decoration boxes, frames and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened thermoplastic sheets such as PVC and PET are molded into various shapes of vacuum covers, blister trays, blisters, etc. through molds. [0003] At present, most of the molds in the blister machine in the prior art are fixed on the body of the blister machine by screws. It is troublesome to replace the mold, which affects the production progress, and frequent disassembly and a...

Problems solved by technology

[0003] At present, most of the molds in the blister machine in the prior art are fixed on the body of the blister machine by screws. It is troublesome to replace the mold, which affects the production progress, and frequent disassembly and assembly of screws will cause The deformation of the threaded hole on the body of the blister machine will cause the installation position of the mold to shift or loosen, and the mold is prone to vibration during the process of extrusion and blistering, resulting in damage to the mold. The size and shape of the mold are fixed, which affects the normal production of the product
