Die-casting die for automobile end cover

Abstract

The invention relates to a die-casting die for an automobile end cover. The die-casting die comprises a die-casting device, a die set, a fixed die, an upper movable die, a lower movable die, an injection opening, a heat preservation injection device, a pipeline pressure chamber, an injection head, a pressure sensor, an injection temperature sensor, an ejection device, a hardness detection device and a center control module. According to the die-casting die, the volume of metal liquid injected into the die set is calculated through the center control module, the volume of the metal liquid injected into the die set is controlled by adjusting the injection speed of the injection head, and the compactness of metal casting is guaranteed, so that the defects of the metal casting are reduced; and the hardness of the metal casting is detected through the hardness detection device, a standard hardness range of the metal casting is set in the center control module, the hardness of the metal casting is compared with the standard hardness range of the metal casting through the center control module, casting pressure is adjusted, the hardness of the metal casting reaches the standard range, and the mechanical property of the metal casting is ensured.

Description

technical field [0001] The invention relates to the technical field of die casting, in particular to a die casting mold for an automobile end cover. Background technique [0002] With the continuous growth of the national economy and the implementation of building a well-off society in an all-round way, the continuous increase in residents' income will promote the upgrading of the consumption structure. The purchase of cars will drive the development of the automobile industry. With the development of the automobile industry, the requirements for automobile manufacturing technology will also increase. [0003] Die-casting is a kind of metal casting process. The basic process of die-casting is that the molten metal is cast and filled into the cavity of the mold at low or high speed. The mold has a movable cavity surface, which is pressurized and forged with the cooling process of the molten metal. , which not only eliminates the shrinkage cavity and shrinkage defects of the ...
