Mould locking mechanism and injection molding machine

Abstract

The invention discloses a mold locking mechanism and an injection molding machine. The mold locking mechanism comprises a tail plate, a cover plate, a guide rod and a push plate; the cover plate is arranged on one side of the tail plate and fixedly connected with the tail plate, and the tail plate and the cover plate jointly define a containing cavity; and the length direction of the guide rod extends in the direction from the tail plate to a fixed mold plate, the two ends of the guide rod are slidably connected with the tail plate and the cover plate respectively, and the guide rod can slide in the length direction. According to the technical scheme, the push plate is arranged in the containing cavity defined by the tail plate and the cover plate; the guide rod is fixedly connected with the push plate, the two ends of the guide rod are connected with the tail plate and the cover plate in a sliding mode respectively, so that the guide rod and the tail plate as well as the guide rod and the cover plate slide relatively, and no relative sliding exists between the push plate and the guide rod to cause abrasion gaps; and due to the fact that the length be tween the two ends of the guide rod is greater than the size of the push plate in the length direction of the guide rod, so that when an abrasion gap is formed between the guide rod and the tail plate and / or between the guide rod and the cover plate, the influence of the abrasion gap on the push plate is small, and the turnover of the push plate is reduced.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a mold locking mechanism and an injection molding machine using the mold locking mechanism. Background technique [0002] The injection molding machine needs to use a mold clamping mechanism when realizing the injection molding process. The mold clamping mechanism has a moving platen and a fixed platen that are set opposite to each other. The side of the moving platen away from the fixed platen is also connected with a push plate. When the push plate moves, it drives the movable platen away from the fixed platen. Or close to the fixed template to realize the opening and closing action of the mold. In order to have a better guiding effect when the push plate moves, a tail plate is usually fixedly installed on the side of the push plate away from the fixed formwork. superior. However, in the traditional clamping mechanism, the push plate is slidingly connected to the gu...
