Vacuum melting die-casting equipment

Abstract

The invention provides vacuum melting die-casting equipment which comprises a melting device, an injection device, a first driving device, a product forming mould and a second driving device, wherein the first driving device can drive the injection device to reciprocate in the melting device; the melting device is in sealed connection with the first driving device and the product forming mould respectively; the second driving device is connected with the product forming mould and can control the opening/closing of the product forming mould; and the vacuum melting die-casting equipment is characterized in that: the melting device comprises a vacuum cylinder, a material pipe and a radio-frequency induction coil, wherein the vacuum cylinder provides a vacuum environment for the melting; the material pipe is located in the vacuum cylinder and used for placing a metal blank; and the radio-frequency induction coil is located outside the vacuum cylinder, contacts with the vacuum cylinder and can heat the metal blank in the material pipe. After the melting is finished, the driving device drives the injection device to finish the injection process, and the injection device injects from bottom to top. The vacuum melting die-casting equipment has a simple structure and relatively low cost, and is convenient to operate.

Description

technical field [0001] The invention belongs to the field of metal forming equipment, in particular to melting and die-casting equipment for various easily oxidizable metals and their alloys. Background technique [0002] Metals and alloys with excellent physical, chemical, mechanical properties and precision formability are key materials to support future high-tech industries such as precision machinery, information, aerospace devices, and national defense industries. However, the preparation conditions of most new metals and alloys are harsh. For example, the properties of Mg alloys and amorphous alloys are sensitive to oxygen content, which requires their smelting and forming processes to be carried out under vacuum conditions. [0003] Existing vacuum die-casting equipment almost completes the die-casting process under atmospheric conditions, which is likely to cause oxidation of metal products, and the products are prone to form pores. Therefore, how to complete the sm...
