Alloy liquid extrusion casting and forming device and technical method thereof

Abstract

The invention discloses an alloy liquid extrusion casting and forming device which comprises a liquid material chamber (1), a hammerhead (2), a sealing slide way (3), a pouring slot (4), a stationary workbench (71), a sealing cutter and an injection device (76). In the invention has the technical scheme, from bottom to top, an alloy liquid material is firstly injected under low pressure into a die cavity for mold filling, and then extruded under high pressure until the alloy liquid material is cooled, cured and formed into products in the die cavity. By adopting the technical scheme, the invention overcomes the defects of elaborate procedures, low efficiency, high cost, poor quality and great energy consumption existing in the prior art. The provided alloy liquid extrusion casting and forming device and a technical method thereof enable the alloy casting products to have perfect exhausting, no cold lap, sufficient casting, no flash, compact structure, fine and close crystal grain, high mechanical performance and high dimension precision as well as be subject to thermal treatment and welding. Thus, alloy liquid forming production achieves the purposes of high quality, high efficiency, low cost and low energy consumption.

Description

technical field [0001] The invention relates to a liquid alloy forming process method and its device, specifically refers to a liquid alloy extrusion casting that injects alloy material liquid from bottom to top into the mold cavity, fills the mold at low pressure in liquid state, and extrudes at high pressure in plastic state. Forming device and process method thereof. Background technique [0002] The alloy liquid forming process of the prior art is divided into high pressure casting method, low pressure casting method (including gravity casting) and casting forging method; [0003] The high-pressure casting method uses a high-pressure, high-speed die-casting machine to inject hot liquid magnesium and aluminum alloy into the cavity of the molding mold to cool and shape the product to complete the molding. This technology has the characteristics of fast filling speed and is suitable for thin-walled and complex The production of parts, but poor exhaust often occurs during t...

AI Technical Summary

Problems solved by technology

[0005] Casting and forging method is to use low pressure or gravity casting to produce the casting blank first, then heat the casting blank and then squeeze and forge it through the mold. This technology has the disadvantages that the forging is easy to be squeezed and forged, resulting in flash and poor dimensional accuracy. Advanced molding defects, and secondary processing energy consumption, waste of man-hours, high overall cost and other deficiencies

Therefore, the prior art has the problems and deficiencies of many processes, low efficiency, high cost, poor quality, and large energy consumption.
