Pulse discharge auxiliary die-casting device and method

Abstract

The invention discloses pulse discharge auxiliary die-casting device and method, relates to discharge plasma die-casting device and method, belongs to the field of die-casting technologies and aims to solve the problems that the existing die-casting technology is high in energy consumption, preparation material is low in density, complex parts cannot be manufactured due to uneven pulse discharge temperature and pressure in the pulse discharge sintering technology. The pulse discharge auxiliary die-casting device comprises a feed rod, a hopper cover, a hopper, a graphite die, a graphite electrode, an auxiliary die, a die and a guide tube. The graphite die, the graphite electrode, a copper electrode and a graphite press head are added on the basis of conventional die-casting for pulse discharge, raw material applies machining residual metal scrap or waste metal fragments, material is placed in the hopper and pushed into the graphite die to be subjected to vacuum pumping, strong pulse is applied to two ends of the material to melt the material, and molten metal is extruded into a die cavity for forming. The pulse discharge auxiliary die-casting device and method are mainly applied to the die-casting technical fields, and waste raw material is effectively utilized to achieve environment friendliness.

Description

technical field [0001] The invention relates to a discharge plasma die-casting device and method, belonging to the technical field of die-casting. Background technique [0002] With the development of science and technology, people's demand for materials and energy is increasing. On the one hand, we need to develop new energy and mine raw materials. From the perspective of sustainable development, we need to learn more about how to save energy and how to make full use of raw materials. to find new solutions. Just imagine that if the used materials, such as aluminum coke cans, can be recycled and reused, the above problems can be effectively dealt with. [0003] The traditional die-casting process is to use the molten metal to enter the cavity under the action of the punch and then solidify and form. For scrap metal, it needs to be re-melted, which will cause oxidation and material loss. At the same time, during die-casting, the melt needs to be kept warm, which requires mo...
