Abstract

The invention discloses a demolding structure of a long sliding block core-pulling mold. The demolding structure comprises a lower die plate, an upper die plate located above the lower die plate, a material stirring plate located above the upper die plate, a shoveling machine, a sliding block module and an oil cylinder assembly. A die cavity is formed between the upper die plate and the lower dieplate; the material stirring plate, the upper template and the lower template can realize mold opening or mold closing along the up-and-down direction; the sliding block module is fixed to the right side of the demolding structure of the long sliding block core-pulling mold. The sliding block module comprises a sliding block and an insert, one end of the insert is fixed to the sliding block, the other end of the insert protrudes into the die cavity, the oil cylinder assembly drives the sliding block and the lower die plate to move relatively, the right end of the upper die plate penetrates inthe vertical direction to form a shoveling machine hole, one end of the shoveling machine is fixed to the material stirring plate, and the other end of the shoveling machine penetrates through the shoveling machine hole to be linked with the sliding block. The shoveling machine is designed to be matched with the sliding block, so that the initial adhesive force between the insert and the injectionmolding part is removed during mold opening, the insert cannot be taken out of the injection molding part when the air cylinder assembly drives the insert to be pulled out, and the product yield is further improved.
