Abstract

The invention provides a heating device for a semi-solid die-casting machine. The heating device comprises a shell and a material cylinder sleeved with the shell. A heat conduction layer is arranged between the shell and the material cylinder, and a cooling layer is arranged between the shell and the heat conduction layer. A gas inlet pipe and a gas outlet pipe are arranged on the shell, one end of the gas inlet pipe stretches into the cooling layer, the other end of the gas inlet pipe stretches out of the shell, one end of the gas outlet pipe stretches into the cooling layer, and the other end of the gas outlet pipe stretches out of the shell. The heating device for the semi-solid die-casting machine is beneficial to balanced temperature distribution and ensures the flowing uniformity of semi-solid paste, the temperature of the paste in the material cylinder can be monitored in real time, and automatic temperature regulating and heat preserving functions are achieved.

Description

technical field [0001] The invention belongs to the field of semi-solid die-casting, and in particular relates to a heating device for a semi-solid die-casting machine. Background technique [0002] The forming temperature of semi-solid die-casting is low, and the thermal shock to the die-casting mold can prolong the life of the abrasive tool. The finished product has a fine and uniform structure, high material strength, lower cost than forging method, and fast production rate. At present, aluminum-magnesium alloys are mainly used in industrial applications, and these alloys are mainly concentrated in the automotive field. However, due to the coexistence of solid phase and liquid phase in the semi-solid slurry, the temperature of the slurry will drop after it flows into the injection chamber from the pulping chamber, and the unbalanced temperature will lead to changes in the solid phase ratio and liquid phase ratio in the slurry, resulting in uneven product punching. Theref...
