New Die Casting Machine

Abstract

The invention relates to a novel die casting machine, and belongs to the field of extrusion casting and pressure casting machines. In a structure of the die casting machine, an extrusion die-casting die is arranged between a static plate and a movable plate of the die casting machine; the extrusion die-casting die consists of a fixed die and a movable die; a fixed die core is connected with a fixed die plate; an inclined pin and a wedge block are arranged on the fixed die plate; a movable die core is connected with a movable die plate; a side sliding block and an extrusion core are arranged on the movable die core; the movable die plate is connected with a support; the support is positioned on the outer side of the side sliding block; an extrusion oil cylinder and an extrusion piston are arranged on the support; an extrusion reversing valve is arranged on the movable die plate of the die casting machine; a rotary encoder and a grating ruler are arranged on an injection frame and an injection piston connection plate of the die casting machine; and the rotary encoder is connected with the original programmable controller. In the novel die casting machine, defect positions of die castings manufactured by the ordinary die casting process are subjected to local extrusion and feeding by the extrusion die-casting die, so the aims of ordinary die-casting filling and extrusion die-casting feeding are fulfilled.

Description

technical field [0001] The invention relates to a die-casting machine, which belongs to the field of squeeze casting and pressure casting machinery and equipment. Background technique [0002] Although the domestic die-casting industry is developing rapidly, the existing die-casting machines can only meet the production requirements of ordinary die-casting processes, and the die-castings produced by ordinary die-casting processes have problems such as cracks, cold shrinkage, substandard air-tightness and relatively low mechanical strength. . On the other hand, the extrusion die-casting process can solve the quality problems of the die-casting products produced by the original simple die-casting process. However, the existing common die-casting machine is not equipped with the application function of the extrusion die-casting mold, which cannot meet the requirements of the extrusion die-casting process. Contents of the invention [0003] In order to solve the above existi...
