Abstract

The invention discloses a mold opening and closing method for a mold closing device of a two-plate type injection molding machine. The mold closing device 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 arranged at one ends of the pull rods (3), and the other ends of the pull rods (3) are sleeved by the movable mold plate (2); the mold closing device of the injection molding machine further comprises front screw nuts (5), rear screw nuts (6), a large gear ring (7) and a power mechanism for driving the large gear ring (7) to rotate, the front screw nuts (5) are in one-to-one correspondence with the pull rods (3), external threads matched with the rear screw nuts are arranged on the pull rods (3), the rear screw nuts (6) are also in one-to-one correspondence with the pull rods (3) and fixedly connected on the movable mold plate (2), the outer edges of the front screw nuts (5) are set to be like gears, the large gear ring (7) is meshed with each front screw nut (5), and the large gear ring drives the front screw nuts to rotate under the drive of the power mechanism. According to the mold opening and closing method disclosed by the invention, a mold locking oil cylinder is not required, and energy consumption in mold locking is reduced by self-locking of the mechanism.

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 device of a two-platen 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 T...
