Vacuum Die Casting System

Abstract

The invention discloses a vacuum die-casting system, which includes a vacuum chamber body and a die-casting machine in the vacuum chamber body, and also includes an external control feeding system located outside the vacuum chamber body to provide quantitative die-casting raw materials for the die-casting machine. The external control feed system It includes a storage box and a feeding hopper. The storage box is installed above the feeding hopper. A normally open relay switch is connected between the outlet of the storage box and the inlet of the feeding hopper to control its opening and closing. A weight sensor, a normally closed relay switch and a weight sensor controlling its opening and closing are connected between the discharge port of the feed hopper and the feed port of the die-casting machine storage mechanism. The vacuum die-casting system in the present invention can not only realize automatic quantitative feeding, make the die-casting process fully automatic, but also improve the efficiency of the die-casting process.

Description

technical field [0001] The invention relates to a vacuum die-casting system, in particular to a vacuum die-casting system capable of quantitative feeding. Background technique [0002] Vacuum die-casting method is a die-casting process that significantly reduces the pores in die-casting parts by extracting the gas in the die-casting mold cavity during the die-casting process. The die-casting process is usually carried out through a vacuum die-casting system. The vacuum die casting method can not only eliminate or reduce the pores inside the die casting, improve the mechanical properties and surface quality of the die casting, but also greatly reduce the back pressure of the cavity, and can be used to prepare castings with poor casting performance or thinner castings, such as in In the preparation process of amorphous alloy castings, the method of vacuum die casting is preferred. In the prior art, the working process of using the vacuum die-casting system to prepare amorphou...

AI Technical Summary

Problems solved by technology

[0004] Although the above method has been improved, the protective gas in the vacuum chamber will cause some defects in the product during high-temperature molding, such as difficulty in filling the mold during die-casting, and the protective gas involved in the die-casting, which will increase the internal porosity of the product, etc.

Moreover, when it comes to appearance products, the surface pores caused by the shielding gas will reduce the product yield and increase the production cost.

At the same time, the consumption of protective gas in the production process will also increase the production cost
