Abstract

The inventiondiscloses a self-locking clamping mechanism of an injection molding machine. The self-locking clamping mechanism comprises a fixed mold plate (1), a movable mold plate (2), pull rods (3) and a mold moving oil cylinder (4), wherein the fixed mold plate (1) is fixed to one end of the pull rods (3), the movable mold plate (2) is arranged at the other end of the pull rods (3) in a sleeving manner, and a piston end of the mold moving oil cylinder (4) is connected with the movable mold plate (2) to drive the movable mold plate (2) to move. The clamping mechanism further comprises a mold locking structure, wherein the mold locking structure comprises rear nuts (5) corresponding to the pull rods (3) in a one-to-one mode, a large gear ring (6) and a power mechanism for driving the large gear ring (6) to rotate, the rear nuts (5) are screwed onto the pull rods (3), the outer edge of each rear nut (5) is in a gear shape, and the large gear ring is meshed with the rear nuts (5) respectively under the drive of the power mechanism and drives the rear nuts to rotate on the corresponding pull rods. The self-locking clamping mechanism does not need a mold locking oil cylinder and reduces the energy consumption of mold locking through self-locking between mechanisms.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a self-locking mold clamping mechanism of the 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 large The oil cylinder has a large pow...
