High-rigidity two-plate die locking mechanism

Abstract

The invention relates to a high-rigidity two-plate die locking mechanism which comprises a fixed die plate, a moving die plate and four pull rods, wherein after correspondingly penetrating through four through holes I formed in four corners of the fixed die plate, the fixed ends of the four pull rods are spirally connected with four pull rod nuts correspondingly, and then connected onto the fixeddie plate; after correspondingly penetrating through four through holes II formed in four corners of the moving die plate, the moving ends of the four pull rods are fixedly connected onto four brake mechanisms arranged on the outer side of the moving die plate correspondingly, and then the moving die plate is connected to the fixed die plate along the reciprocating motion of the four pull rods relative to the fixed die plate; the four pull rod nuts are all connected to one and the same driving mechanism through one and the same transmission mechanism; and under the drive of the driving mechanism, the positions of the four pull rods on the fixed die plate are synchronously adjusted. According to the high-rigidity two-plate die locking mechanism provided by the invention, the brake positiondifference which needs to be compensated for due to the different die thicknesses can be automatically compensated for by slightly adjusting the relative position between the four pull rods and the fixed die plate, and then the influence of the compressibility of hydraulic oil on the rigidity of the high-rigidity two-plate die locking mechanism can be reduced to the minimum.

Description

technical field [0001] The invention relates to a high-rigidity clamping mechanism in injection molding equipment and die-casting equipment, in particular to a two-plate high-rigidity clamping mechanism. Background technique [0002] At present, in the plastic processing, metal die-casting and rubber processing industries, most of the clamping mechanisms used in injection molding equipment and die-casting equipment are two-platen, referred to as the second-platen machine. The two-plate mold clamping mechanism has been widely used because of its simple and compact structure and ease of use. The two-plate mold clamping mechanism 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, and a clamping cylinder and a clamp for driving the movable template to move relative to the fixed template. brake components, etc. [0003] In the existing two-plate clamping mec...
