Abstract
The utility model discloses a mechanism for separating slide blocks on all sides from a plastic product, belonging to the field of a thermoplastic molding mold. The mechanism is characterized in that a fixed die seat plate and a fixed template are flicked under the action of tension of a spring in a die sinking process; a tapered wedge fixed on the fixed die seat plate drives a fixed die slide block to move, so that the fixed die slide block is separated and the back-off part on the outer side of the plastic product is taken off. Meanwhile, due to the limited opposite-insertion separation to a movable die internal core-pulling block caused by the fixed die slide block, the movable die core-pulling slide block is subjected to internal core-pulling under the action of the tension of the spring by limitation, and the back-off part at the inner side of the plastic product is taken off. The tapered wedge guides the fixed die slide block to move in the die assembly process, so that the fixed die slide blocks on two sides are in surface contact, and meanwhile, a conical lug boss of each fixed die slide block contacts a conical groove in the top of the movable die core-pulling slide block, so as to finish die assembly. Back-off separation of the product in four directions is achieved by movement of the fixed die slide blocks and the movable die internal core-pulling slide block, the mold structure is simplified, and the production efficiency is improved.
