Abstract

The invention discloses a mold opening and closing method of a self-locking two-plate machine mold closing mechanism, which is based on the self-locking two-plate machine mold closing mechanism. The self-locking two-plate machine mold closing mechanism comprises a fixed mold plate (1), a moving mold plate (2), pull rods (3), a mold movement oil cylinder (4) and a mold locking structure, wherein the fixed mold plate (1) is fixed at one end of each pull rod (3); the moving mold plate is arranged at the other end of each pull rod (3) in a sleeving manner; a piston end of the mold movement oil cylinder (4) is connected with the moving mold plate (2); the mold locking structure comprises rear nuts (5), a big gear ring (6) and a power mechanism driving the big gear ring (6) to rotate; the rear nuts (5) are screwed on the pull rods (3); the outer edges of the rear nuts (5) are arranged into gear shapes; and the big gear ring is engaged with the rear nuts respectively, and drives the rear nuts to rotate on the corresponding pull rods. The method requires no mold locking oil cylinder, and reduces energy consumption of mold locking by utilizing self-locking between the mechanisms.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a mold opening and closing method for a mold clamping mechanism of a self-locking two-platen machine. Background technique [0002] The mold clamping structure of the existing two-platen injection molding machine mainly includes hydraulic direct locking type and compound type. Among them, the working process of the hydraulic direct locking type is mainly: firstly, the movable template is moved through the fast mold moving cylinder, and then the tie rod is locked through the brake structure, and then the mold is locked through the locking cylinder. The hydraulic direct locking type has automatic adjustment. mold function, but the required hydraulic system is relatively complex, the reliability is poor, and the occupied space has no obvious advantages compared with the three-platen injection molding machine, especially when the clamping force is large, four very large The...
