Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a device for recycling hydraulic fluid in the die casting process of housings. Background Technology

[0002] Die casting is a high-precision, high-efficiency metal forming technology mainly used to produce various metal shell parts. It combines the characteristics of casting and pressure processing, rapidly injecting molten metal into a mold cavity under high pressure and solidifying it in a short time to obtain castings with complex shapes and high-precision dimensions. The core of die casting is to use high pressure to rapidly inject molten metal into the mold cavity and solidify it under high pressure.

[0003] Metal smelting involves heating metal materials to a molten state. Mold preparation involves heating the mold to a suitable temperature and applying a release agent to prevent the casting from sticking. Injection molding involves rapidly injecting molten metal into the mold cavity under high pressure, with filling speeds reaching tens of meters per second. Finally, solidification occurs as the molten metal rapidly cools and solidifies within the mold cavity, forming the desired shell shape. Die casting can produce castings with high dimensional accuracy and good surface quality, typically achieving an accuracy level of IT6-IT8. It is suitable for producing complex-shaped, thin-walled shell parts, such as automotive engine blocks, gearbox housings, and electronic device enclosures.

[0004] Currently, in the die casting process for housings, the hydraulic system is a key part for the normal operation of the die casting machine. During use, the performance of hydraulic fluid will decline due to factors such as temperature rise and impurity contamination. In traditional processes, the hydraulic fluid usually needs to be replaced frequently, which not only increases production costs but also has a certain impact on the environment. Therefore, a hydraulic fluid recycling device is needed in the die casting process for housings to improve the above problems. Utility Model Content
