Embodiment Construction

[0020] Such as figure 1 As shown, the fixed template 2 and the movable mold 7 are located above the injection mechanism. When the squeeze casting machine closes the mold, the fixed template 2 and the movable mold 7 are pasted together to form a closed mold cavity space, and there is a circle below Shaped sprue sleeve 8. A rotating bracket 9 is fixed on the fixed template 2, and the injection mechanism is hung on the rotating bracket 9 through an intermediate rotating shaft 11. The injection rod 4 is connected to the bottom of the barrel 3, and the oil cylinder 6 is connected to the bottom of the injection rod 4. The injection rod 4 is used to complete the filling. There is a square barrel fixing plate 10 at the bottom of the barrel 3, and the barrel fixing plate 10 Two barrel piston pressure rods are connected below, and the effect of the piston pressure rod is to lift and lower the barrel, and the lifting and lowering of the barrel 3 are realized by moving up and down of the...

Abstract

The invention discloses a press-shooting system for an extrusion casting machine to overcome the technical defects of press-shooting systems for existing extrusion casting machines. The press-shooting system comprises a feeding mechanism and a press-shooting mechanism. The press-shooting system can be applied to a vertical extrusion casting machine. The press-shooting system solves the problems of existing extrusion casting machines that feeding is inconvenient and unsteady, air entrapment occurs easily, the size of a casting in the thickness direction is hard to control, press-shooting stability is low, the occupied space of a press-shooting system is large, and a working table is too high.

Description

technical field [0001] The patent of the invention belongs to the field of casting machinery, and in particular relates to an injection system of a squeeze casting machine. Background technique [0002] With the development of the foundry industry, people have put forward higher requirements for the mechanical properties, appearance and complexity of castings, especially for castings with high requirements for wall thickness and microstructure performance, and castings that require heat treatment, it is very difficult to adopt ordinary gravity casting and die casting. difficult to meet the requirements. Squeeze casting combines the dual advantages of casting and forging. The casting has compact structure, high dimensional accuracy, smooth surface, can be followed by heat treatment, and has good mechanical properties. The squeeze casting process is a new technology that realizes the combination of casting and forging. Lightweight, precision, and environmental protection are...
