First, according to the design requirements and shape of the product, the die-casting mold is designed, and the die-casting mold is manufactured according to the designed mold drawing. Before starting die-casting, the mold needs to be prepared, including cleaning the mold surface, applying lubricant, and installing the mold. In order to ensure uniform temperature during die-casting, the mold needs to be preheated to reach a suitable working temperature. Start the top die-casting cylinder 10 to connect and fix the upper mold 15 and the lower mold 20. Then, pour the molten metal into the prepared mold through the casting port 13. Then, start the vacuum pump 22 and the valve 5 to extract the air in the vacuum chamber 22. At the same time, inject condensed water into the heat dissipation member 19 through the water inlet 17. The condensed water cools the outer mold 23 through the circulating water channel and then leaves through the water outlet 17. Keep the pressure and let the metal cool and solidify to form.

Subsequently, start the vacuum pump 22 and the valve 5 to extract the air in the vacuum chamber 22. The vacuum pump 2 is used to create and maintain a low-pressure or vacuum environment inside the device, so that the temperature inside the mold is uniform when the internal device dissipates heat. The valve 5 can be used to control the working state of the vacuum pump 2, thereby precisely adjusting the vacuum degree or pressure inside the device. The existence of the vacuum chamber 22 and the outer mold 23 enables the device to maintain low temperature and low pressure while ensuring the quality and precision of the product.

The water channel 18 is a spiral rising structure and is fixedly connected to the heat sink 19.
[0033] Preferably, inject condensed water into the heat sink 19 through the water inlet 17. The condensed water cools the outer mold 23 through the circulating water channel and then leaves through the water outlet 17, maintaining the pressure and allowing the metal to cool and solidify for molding. A water channel 18 is provided at the internal position of the heat sink 19, a water inlet 17 is provided at the bottom position of the heat sink 19, and a water outlet 16 is provided at the upper left position of the heat sink 19.

An opening corresponding to the positioning member 14 is provided inside the nesting sleeve 6, and the nesting sleeve 6 is nested and connected with the positioning member 14. The base 1 and the top cover 8 are made of steel structure, and the shock-absorbing ring 3 is fixedly connected to the positioning member 14.
[0035] Optionally, the steel structure can provide sufficient strength and hardness to withstand the high-pressure and high-load stamping process, which enables the mold to maintain a stable shape and size during long-term use. The shock-absorbing ring 3 can absorb and disperse vibration and impact force, reducing the vibration and impact transmitted to the positioning member 14 and other components. Through the fixed connection with the shock-absorbing ring 3, the shock-absorbing ring 3 can provide additional stability and rigidity, ensuring that the positioning member 14 can maintain an accurate position and posture.
