The production of aluminum die casting is an indispensable process in modern manufacturing industry, and its product quality is closely related to the pressure control of die casting in the production process. This paper introduces the control method of pressure of die casting in the production of aluminum die casting, in order to improve the production efficiency and product quality.
The production process of aluminum die casting is by pouring aluminum liquid into the mold, applying pressure to fill it to all corners of the mold, and then cooling the aluminum liquid to form aluminum die casting. In this process, the size of the die casting pressure has a crucial impact on the quality of the product. If the pressure of die casting is too small, the aluminum liquid can not completely fill the mold, resulting in problems such as pores and cracks in the product; If the pressure of die casting is too large, the aluminum liquid is filled too quickly, resulting in problems such as bubbles and poor surface quality. Therefore, in the production of aluminum die casting, it is very important to control the pressure of die casting.
A method for controlling the pressure of die casting
1. Adjust the pressure of the filling gas: In the production process of aluminum die casting, the pressure of the filling gas has a direct impact on the size of the pressure of the die casting. Therefore, adjusting the pressure of filling gas is an effective way to control the pressure of die casting. Specifically, the pressure of the filling gas can be changed by adjusting the output pressure of the air compressor.
2. Keep the mold temperature: The temperature of the mold will also affect the size of the pressure of the die casting. If the mold temperature is too low, the aluminum liquid will become viscous, requiring greater pressure to fill the mold; If the mold temperature is too high, the liquid aluminum will become fluid and poor filling, resulting in insufficient filling. Therefore, keeping the mold temperature stable is also one of the important ways to control the pressure of die casting.
3. Control the flow rate and pressure of the filled gas: in the production process of aluminum die casting, the flow rate and pressure of the filled gas will also affect the size of the pressure of the die casting. Therefore, controlling the flow rate and pressure of the filling gas is also one of the important ways to control the pressure of the die casting. Specifically, the flow rate of the filled gas can be controlled by adjusting the flow rate of the gas flowmeter, and the pressure of the filled gas can be controlled by adjusting the output pressure of the gas manometer.
How to control the pressure of die casting in the production of aluminum die casting? In the production process of aluminum die casting parts, in order to control the size of the pressure of die casting, some technical guidance needs to be taken. First of all, it is necessary to choose the right air compressor and gas flow meter to ensure that the pressure and flow rate of the filled gas can meet the production requirements. Secondly, it is necessary to choose the appropriate filling gas and gas pressure gauge according to different production conditions to ensure the stability of the die casting pressure. Finally, it is necessary to adjust the flow rate and pressure of the filling gas according to the different requirements of the product to ensure the quality and performance of the product. In short, how to control the pressure of die casting when aluminum die casting is produced? In the production process of aluminum die casting, it is very important to control the pressure of die casting. By adjusting the pressure of the filling gas, maintaining the mold temperature and controlling the flow rate and pressure of the filling gas, the size of the pressure of the die casting can be effectively controlled, so as to improve the quality and performance of the product. In the future, with the development of technology and the continuous progress of technology, it is believed that the pressure control method of die casting in the production of aluminum die casting will also be continuously improved and improved
