Electric pull rod-adjustable mould clamping mechanism

Abstract

The invention discloses an electric pull rod-adjustable mould clamping mechanism. The mechanism comprises an ejection mechanism, a brake mechanism, a moving template, a pull rod, a fixed template, a high-pressure mould clamping cylinder and a quick mould moving cylinder, wherein the ejection mechanism is arranged on the moving template; the quick mould moving cylinder moves the moving template; the brake mechanism is arranged on the moving template; the brake mechanism brakes the pull rod through a brake nut of the brake mechanism; the electric pull rod-adjustable mould clamping mechanism is also provided with an electric pull rod adjusting mechanism which comprises a speed reducer, a servo motor, a speed reducer connection end cover, lead screws of a lead screw pair, screw nuts of the lead screw pair and a pull rod nut, wherein the servo motor is connected with the speed reducer; the speed reducer is fixed on the speed reducer connection end cover; the speed reducer connection end cover is fixed at the front end of the mould clamping cylinder; the front cover of the mould clamping cylinder is fixed on the fixed template; the servo motor is connected with the lead screws of the lead screw pair; and the screw leads of the screw lead pair are matched with the screw nuts of the screw lead pair which is fixed on the head of the pull rod.

Description

technical field [0001] The invention relates to a component of an injection molding machine, in particular to a mold clamping mechanism of an injection molding machine. Background technique [0002] At present, in the domestic injection molding machine industry, the connecting rod type clamping device occupies the main position, and its structure is as follows figure 1 As shown, the defect of its structure is that for a certain tonnage machine, the mold opening stroke is limited by the structure, and the stroke should not be too large. For some products with deep cavity holes, this kind of machine cannot meet the requirements of the product, and the structure of the connecting rod machine is also more complicated. When the tonnage of the machine is relatively large, the length and weight of the machine are relatively large, and the cost will be corresponding improved. [0003] In industrially developed countries such as Germany, the United States, and Japan, most of the la...

AI Technical Summary

Problems solved by technology

[0014] 1. The structure of the head plate is complex, the processing cycle is long and difficult

[0015] 2. The clamping cylinder has a long stroke and a large oil consumption

[0016] 3. Poor mold breaking accuracy

[0017] 4. To disassemble the machine, the pull rod must be removed. Opening the cylinder head will waste hydraulic oil and damage the seals
