Swinging type squeezing system

Abstract

The invention provides a swinging type squeezing system. A sprue sleeve commonly consisting of a movable die and a fixed die of a die is located on the main axis of a squeezing system of a squeezing casting machine; and a material cylinder is arranged right under the die splitting face of the die. Main movement realized by the material cylinder is in swinging type; the material cylinder is fed in an inclined manner, the entrapping of air is difficult to occur; the material cylinder aligns to the sprue sleeve, so that the material sleeve is lifted up and is abutted against the sprue sleeve; a punching head in the material cylinder is raised to push a metal liquid to enter into a die cavity from bottom to top; and meanwhile, air in the die cavity is raised and externally overflows through an exhaust channel, so as to form a casting piece. When the thickness of the fixed die is changed, the position of the material cylinder in a horizontal direction can be adjusted, so that the material cylinder can accurately align to the sprue sleeve. With the adoption of the swinging type squeezing system provided by the invention, the problems that squeezing, casting and feeding are inconvenient and unstably, the size precision of the casting piece in a thickness direction is difficult to ensure and the automation degree of the equipment is low can be solved.

Description

technical field [0001] The patent of the present invention relates to the oscillating extrusion system of the horizontal squeeze casting machine in the foundry machinery industry. The structure of the oscillating extrusion system of the present invention is an adjustable oscillating extrusion system, and its principle can also be used in the vertical squeeze casting machine . Background technique [0002] Squeeze casting technology has the dual advantages of compact forging structure, high mechanical performance and good casting formability, and at the same time overcomes the shortcomings of forging anisotropy, so it quickly became a hot spot in special casting technology. The development has greatly promoted the development of squeeze casting machines. [0003] According to the current literature and books, the molten metal of the squeeze casting machine generally enters the mold cavity and extrudes in the above feeding mode, as in the fifth chapter of "Practical Technolog...
