The invention provides an integrated device of the hot injection molding technology. The integrated device of the hot injection molding technology comprises a stirring material preparing system, a die casting system and a machine shell. The stirring material preparing system comprises a stirring tank, a stirring machine and a lifting machine. A tank body of the stirring tank is arranged to have an inner layer and an outer layer, and a cavity is formed between the outer layer of tank body and the inner layer of tank body. The cavity is filled with heat conduction silicone oil, and a heater and a temperature sensor are arranged. A discharging opening is further formed in the bottom of the stirring tank. The die casting system comprises a material liquid pipeline, a material outlet, a support and a pressing device. The material liquid pipeline is arranged between the discharging opening and the material outlet. The material outlet is formed in the upper surface of the machine shell and is further formed in the central axis of the support. The support is arranged on the upper surface of the machine shell. The pressing device is arranged in the center of a beam of the support and corresponds to the material outlet. By means of the integrated device of the hot injection molding technology, it is ensured that the temperature of material liquid is uniform through oil bath heating of the stirring tank and a heating belt on the material liquid pipeline, and in addition, the automation degree of the device is relatively high.

The invention relates to a novel high-performance die-casting zinc alloy material, and particularly relates to a novel zinc alloy material suitable for die casting. The zinc alloy novel material comprises the following components in mass percentage by adjusting the percentage content of Al and being matched with a melt treatment process: 3.3-4.3% of Al, 0.02-0.06% of Mg, no more than 0.1% of Fe, no more than 0.005% of Pb, no more than 0.003% of Sn, no more than 0.004% of Cd and the balance Zn. The novel high-performance die-casting zinc alloy material has the higher tensile performance compared with an existing third zinc alloy, and meanwhile, the higher die-casting performance and the lower cost are achieved.
