The working principle of the invention is as follows:

referring to the attached drawings 1-10 of the specification, when the mold core needs to be installed in the shell, firstly, the motor 11 is started, the output shaft of the hydraulic cylinder 5 close to the motor 11 is shortened and then extended, so that the bottom of the upper mold 9 is upward through the transmission structure, and the upper mold 9 is not positioned right above the lower mold 2, then the required upper mold core 17 and lower mold core 21 can be moved to the upper part of the upper shell 15 and lower shell 20 through the electric hoist, then the upper mold core 17 and lower mold core 21 are quickly installed in the upper shell 15 and lower shell 20 through the cooperation among the first wedge groove 18, the second wedge groove 22, the wedge 31, the first threaded hole 19, the second threaded hole 23 and the first bolt 32, and the lower mold core 21 is automatically positioned by the cooperation among the second chute 26, the second positioning shaft 27, the swing rod 28, the limiting block 29 and the limiting column 30 when being placed in the lower shell 20, the installation is convenient, meanwhile, the limiting column 30 is matched with the positioning hole 16 at the bottom of the upper shell 15, the stability in the injection molding process is improved, and then the transmission step is reversely carried out, so that the upper die 9 is reset;

referring to the attached drawings 1-8 of the specification, firstly, a lower die 2 is quickly fixed on a bottom plate 1 through a threaded rod 35, a first through hole 36 and a first nut 37, an upper die 9 is quickly fixed on a positioning block 6 through a second through hole 38, a second bolt 39 and a second nut 40, circulating high-temperature oil is injected through an oil temperature machine 45, an upper die core 17 and a lower die core 21 are heated, then aluminum-magnesium alloy liquid is poured between the lower die core 21 and the upper die core 17 through a liquid inlet pipe 25, after the injection molding is finished, circulating low-temperature oil is injected again through the oil temperature machine 45, so that the aluminum-magnesium alloy liquid is quickly cooled into required parts, then, a motor 11 and a hydraulic cylinder 5 are started, the upper die 9 is turned over after being opened by utilizing a transmission structure, and the injection molded parts are taken out.
