Die-casting die with core-pulling structure provided with extruding pin

Abstract

The invention relates to a die-casting die with a core-pulling structure provided with an extruding pin. The first extruding pin core-pulling structure comprises a first core-pulling oil cylinder support, a first extruding oil cylinder and a first sliding block base. The first sliding block base is installed on a lower die base through first pressing bars of the two sides. A first core-pulling block is installed at one end, close to a die cavity, of the first sliding block base, and a first core-pulling oil cylinder support is installed at the other end of the first sliding block base. A first extruding oil cylinder is installed on the portion, close to the first sliding block base, of the first core-pulling oil cylinder support. The main shaft end portion of the first extruding oil cylinder serves as an extruding head, penetrates through the first sliding block base and the first core-pulling block and is inserted into a die cavity. A first friction bar is installed on the lower end face of the first sliding block base. A locking block is installed on the upper portion, close to one end of the first core-pulling oil cylinder support, of the first sliding block base. The die-casting die has the beneficial effects of being simple in structure and high in production efficiency, ensuring the product quality, reducing the manufacturing cost of the die and the like.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold with extrusion pins on a core-pulling structure. Background technique [0002] Originally, when molds were used to produce shells, the products produced would have problems such as substandard quality, lack of hardness, and a large number of internal air shrinkage cavities. In order to solve the above problems, different core-pulling structures were designed on the mold. The ordinary core-pulling structure The industry index cannot be well achieved, so an auxiliary structure is set on the core-pulling structure, which can further guarantee product quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a die-casting mold with extrusion pins on the core-pulling structure, which has the advantages of simple structure, high production efficiency, guaranteed product quality, reduced mold manu...
