Technical Field
[0001] The utility model relates to the technical field of die-casting machines, in particular to a pressure testing device for a die-casting machine. Background Art
[0002] A die-casting machine is a machine used for pressure casting. It includes two types: hot-chamber and cold-chamber. The latter is further divided into two types: vertical and horizontal. Under pressure, the die-casting machine injects molten metal into the mold for cooling and forming. After the mold is opened, solid metal castings can be obtained. It was initially used for die-casting type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and household appliances, die-casting technology has developed extremely rapidly. The development of die-casting technology has been more than 150 years. In the early 19th century, due to the rise of the printing industry, a type-casting machine for lead type casting came into being. Soon, it evolved into a hot-chamber die-casting machine based on the type-casting machine. Currently, the pressure of existing die-casting machines is mainly directly connected to the control system through a pressure sensor, and the pressure change of the control system is detected through an electrical signal output. However, between the mold platen of the die-casting machine, the pressure distribution is prone to imbalance, making it impossible to accurately measure the accurate values at the edge or center between the platens. There is an easy error between the measured value and the true pressure value between the platens, which is inconvenient for detecting whether the pressure between the platens is balanced.
