Abstract

The invention provides heating equipment for semisolid die-casting slurry. The heating equipment comprises a shell and a barrel. The shell is arranged outside the barrel in a sleeving mode. A heat conduction oil pipe and a condensate pipe are arranged between the shell and the barrel. Heat conduction oil flows in the heat conduction oil pipe. Circulating cooling water flows in the condensate pipe. The shell is provided with an oil inlet pipe and an oil outlet pipe. The oil inlet pipe is connected with one port of the heat conduction oil pipe. The oil outlet pipe is connected with the other port of the heat conduction oil pipe. The shell is provided with a condensate water inlet pipe and a condensate water outlet pipe. The condensate water inlet pipe is connected with one port of the condensate pipe. The condensate water outlet pipe is connected with the other port of the condensate pipe. Through the heating equipment for the semisolid die-casting slurry, temperature distribution equilibrium is facilitated, flow consistency of the semisolid die-casting slurry is ensured, the temperature of the slurry in the barrel can be monitored in real time, and automatic thermoregulation and heat preservation functions are achieved.

Description

technical field [0001] The invention belongs to the field of semi-solid die-casting, and in particular relates to heating equipment for semi-solid die-casting slurry. 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. Therefor...
