Brake assembly and two-plate mold locking device

Abstract

The invention discloses a brake assembly and a two-plate mold locking device. The brake assembly comprises a two-half brake unit, wherein the two-half brake unit comprises two brakes, a drive piece, at least one brake support seat and at least one synchronizing mechanism; one synchronizing mechanism is arranged at at least one end of each brake and comprises two synchronizing racks and asynchronizing gear, the two synchronizing racks are fixed on the two brakes respectively, and the synchronizing gear is connected with the two synchronizing racks; an output shaft of the drive piece is at least connected with one synchronizing rack of each synchronizing mechanism, so that the two brakes are opened and closed synchronously. The at least one synchronizing mechanism is arranged on the two brakes, so that when one synchronizing rack of the synchronizing mechanism is driven by the drive piece to move, the synchronizing rack is fixedly connected with one of the two brakes, so that the brake moves in the same direction with the synchronizing rack while the other brake moves reversely together with the other synchronizing rack, stable and synchronous opening of the two brakes is realized, and impact caused by non-synchronization is reduced.

Description

technical field [0001] The present invention relates to a brake assembly, in particular to a brake assembly of a two-plate mold clamping device, and also to a two-plate mold clamp comprising the brake assembly. Background technique [0002] At present, in the plastic processing, metal die-casting and rubber processing industries, most of the mold clamping devices used in injection molding equipment and die-casting molding equipment adopt the two-platen type (referred to as the two-platen machine). The two-plate mold clamping device has been widely used because of its simple and compact structure and easy use. The two-plate mold clamping device generally includes a movable template, a fixed template, a tie rod connected between the movable template and the fixed template and for the movable template to move on it, a clamping cylinder and a brake assembly. [0003] The existing two-plate clamping device can be divided into two types according to the setting position of the cl...

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a brake assembly with a synchronization mechanism, the main purpose of which is to solve the problem that the existing two-half brakes cannot be synchronized

Another purpose of the two-plate mold clamping device provided by the present invention is to solve the problem that the sealing surface is easily worn and leaked due to the lateral force generated when the mold clamping cylinder enters high-pressure oil instantly, causing the mold clamping piston to tilt and move.
