Example Embodiment

[0019] As shown in the figure, the fixed mold 1 and the movable mold 2 are arranged above the extrusion system. When the squeeze casting machine closes the molds, the fixed mold 1 and the movable mold 2 are bonded together to form a circular sprue sleeve 3. . There is a suspension frame directly below the sprue bushing. The suspension frame is composed of a fixed upper beam 4, a tie rod 15, and a lifting seat plate 12. The tie rod 15 is provided with an extrusion seat plate 9, and the extrusion seat plate 9 is sleeved on the tie rod 15. It can move up and down along the tie rod 15. The squeezing seat plate 9 is provided with a rotating shaft 10, an angle bracket 8, an squeezing cylinder 13 is provided on the rotating shaft 10, a barrel 17 is provided on the squeezing cylinder 13, and a punch 18 is provided in the barrel 17. A barrel swing cylinder 7 is provided on the angle bracket 8, and the barrel swing cylinder 7 is connected to the barrel 17. A lifting oil cylinder 11 is a...

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...
