Die casting machine

Abstract

A pressure casting machine can be configured to mold a molten material into a workpiece. The pressure casting machine can include a vacuum chamber and a pressure casting mechanism coupled to the vacuum chamber. The vacuum chamber can include a processing section having a top wall and a bottom wall opposite to the top wall, a first gate configured to seal the processing section, and a first vacuum pump coupled to the processing section. The pressure casting mechanism can include a first driver positioned adjacent to the top wall, a first core received in the processing section and coupled to the first driver, a second core received in the processing section, and a plurality of pushing members received in the processing section. The second core can be coupled to the bottom wall and opposite to the first core. The pushing members can be coupled to the top wall.

Description

technical field [0001] The invention relates to a die-casting machine, in particular to a vacuum vertical die-casting machine. Background technique [0002] For anaerobic materials, such as amorphous alloys, during the die-casting process, it is necessary to keep the die-casting environment in a vacuum state, so as to avoid air mixing during die-casting and affect the quality of die-casting parts. In order to ensure the vacuum die-casting environment, the traditional die-casting machine usually realizes it by extracting the gas from the cavity of the die-casting mold. Since the cavity vacuum die-casting machine needs to open a vacuum channel communicating with the mold cavity on the mold and set a vacuum stop valve, the structure of the mold is complicated. And, in order to make the molded die casting fall off from the mold of the die casting machine, an ejection mechanism is often provided on the mold. The ejection mechanism includes a driver and a thimble connected to the...

AI Technical Summary

Problems solved by technology

Since the die-casting raw material fills the cavity under high pressure during die-casting, the die-casting still stays on the mold after the mold is opened, and the driver drives the thimble to protrude from the surface of the mold to eject the die-casting The output method further makes the mold structure more complicated

In addition, the die-casting machine realizes a vacuum environment in the mold cavity, often because there are still gaps between the guide pins, ejector pins and other parts on the mold and the mold body, air will enter the mold cavity from the gap and damage the mold cavity The vacuum environment inside, thus affecting the quality of die castings
