Mold Opening and Closing Method of Clamping Mechanism of Self-locking Two-platen Machine

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 of a self-locking two-platen machine mold clamping mechanism. Background technique [0002] The existing two-platen injection molding machine clamping structure mainly includes two types: hydraulic direct lock type and compound type. Among them, the working process of the hydraulic direct-locking type is mainly: firstly, the template is moved by the quick-moving oil cylinder, then the tie rod is locked by the locking structure, and then the mold is locked by the clamping cylinder. The hydraulic direct-locking type has automatic adjustment However, the hydraulic system required is relatively complex and the reliability is poor. Compared with the three-platen injection molding machine, the occupied space has no obvious advantages, especially when the clamping force is large, four very large injection molding machines are required. The oil...
