Abstract

The invention discloses a mold opening and closing method of a self-locking type mold closing mechanism of an injection molding machine. The self-locking type mold closing mechanism comprises a front mold plate, a movable mold plate, pull rods and a mold transferring oil cylinder, wherein the front mold plate is fixed at one ends of the pull rods, the movable mold plate is arranged at the other ends of the pull rods in a sheathing manner, a piston rod of the mold transferring oil cylinder is connected with the movable mold plate to drive the movable mold plate to move; the self-locking type mold closing mechanism also comprises mold locking structures, wherein the mold locking structures comprise rear nuts corresponding to the pull rods one by one, large gear rings and power mechanisms for driving the corresponding large gear rings to rotate, the rear nuts are screwed on the corresponding pull rods, the outer edge of each rear nut is designed to be a gear shape, and each large gear ring is meshed with the corresponding rear nut under the driving of the corresponding power mechanism and drives the corresponding rear nut to rotate on the corresponding pull rod. According to the mold opening and closing method of the self-locking type mold closing mechanism of the injection molding machine, a mold locking oil cylinder is not used, and the mold locking energy consumption can be reduced due to self locking of mechanisms.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a mold opening and closing method of a self-locking mold clamping mechanism of an injection molding 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 lar...
