The threads on the rod 16 are rotated in opposite directions, so that the two rectangular slides 13 threadedly connected thereto slide in opposite directions. The rectangular slide 13 on the left moves upward, and the rectangular slide 13 on the right moves downward, so that the rectangular sleeve 9 on the left is blocked, and the gas will not be discharged from the first delivery pipe 10. The rectangular sleeve 9 on the right is unblocked, and the gas can be discharged from the second delivery pipe 23. At this time, the second valve 18 and the third valve 19 are in the open state, and the first valve 20 is in the closed state. Then, a delivery pump 31 is started to extract the molten metal in the molten metal tank 29. The molten metal is transported through the metal hose 32 and injected into the lower mold 5 on the left from the injection hole for cooling and molding. During cooling, the heat of the molten metal will heat the first heat exchange seat 3. At this time, the pump 31 is started to extract the molten metal in the molten metal tank 29.

When the lower mold 5 on the right is not needed, just close the third valve 19 and open the first valve 20. At this time, the hot gas discharged from the first heat exchange seat 3 will no longer enter the second heat exchange seat 4, but directly enter the switching pipe 17, enter the hollow plate 22 from the switching pipe 17, and then enter the spiral coil 24 to heat the water, realizing heat energy recovery.

[0068] When in use, the two electric push rods 27 on the left push the upper mold 28 on the left to move downward and cover the lower mold 5 on the left. At the same time, the downward movement of the upper mold 28 will drive the vertical rod 41 to move downward, the vertical rod 41 drives the lifting plate 40 to move downward, the lifting plate 40 drives the rack 39 to move downward, the rack 39 drives the gear 38 to rotate, the gear 38 drives the transmission rod 37 to rotate, the transmission rod 37 drives the first sprocket 42 to rotate, the first sprocket 42 drives the second sprocket 43 to rotate through the chain 44, the second sprocket 43 drives the round rod 33 to rotate, the round rod 33 drives the two first bevel gears 34 to rotate, the two first bevel gears 34 drive the two second bevel gears 35 to rotate, the two second bevel gears 35 drive the two screws 16 to rotate, and the threads on the two screws 16 rotate in the opposite direction. On the contrary, the two rectangular slides 13 threadedly connected thereto slide in opposite directions, the rectangular slide 13 on the left moves upward, and the rectangular slide 13 on the right moves downward, so that the rectangular sleeve 9 on the left is blocked, and the gas will not be discharged from the first delivery pipe 10.

At this time, the second valve 18 and the third valve 19 are in an open state, and the first valve 20 is in a closed state. Then a delivery pump 31 is started to extract the molten metal in the molten metal tank 29. The molten metal is transported through a metal hose 32 and injected into the lower mold 5 on the left from the injection hole for cooling and molding. During cooling, the heat of the molten metal will heat the first heat exchange seat 3. At this time, the fan 8 on the left is started, and the fan 8 blows to the first heat exchange seat 3. The heat exchange cavity on the first heat exchange seat 3 is blown, and the gas takes away the heat through the heat exchange cavity, thereby accelerating the cooling and molding speed. The heat enters the heat exchange cavity on the second heat exchange seat 4 from the connecting pipe 6 to preheat the lower mold 5 on the second heat exchange seat 4. Then the gas enters the second delivery pipe 23, enters the hollow plate 22 from the second delivery pipe 23, and then enters the spiral coil 24 from the hollow plate 22. The residual heat in the gas heats the spiral coil 24, and then the water in the hot water tank 21 is heated by the spiral coil 24. When the heated water is needed, the second water pump 51 is started to extract the hot water in the hot water tank 21, and the hot water is transported to the required position by the water delivery pipe 52. Then the first water pump 49 is started to extract the cold water through the pumping pipe 50, and the cold water is added to the hot water tank 21. By preheating the lower mold 5 on the right, it is possible to prevent the molten metal that enters the lower mold 5 first from cooling faster, resulting in a large temperature difference with the molten metal that enters later, affecting the casting effect. The rotation of the transmission rod 37 can drive the third bevel gear 47 to rotate, the third bevel gear 47 drives the fourth bevel gear 46 to rotate, the fourth bevel gear 46 drives the stirring shaft 45 to rotate, and the stirring shaft 45 drives the stirring blade 48 to rotate, stirring the water in the hot water tank 21 so that the water is heated evenly, and then the upper mold 28 on the left is opened upwards to take out the cooled and formed stainless steel part. At this time, the rectangular sleeve 9 on the left is unblocked, and the rectangular sleeve 9 on the right is blocked. The upper mold 28 on the right is closed downwards through the two electric push rods 27 on the right, and then the molten metal is injected into the lower mold 5 on the right.When the metal liquid injected into the right lower mold 5 needs to be cooled, it is only necessary to start the right fan 8, so as to blow the heat from the right heat exchange cavity to the left heat exchange cavity through the connecting pipe 6, and preheat the left lower mold 5. Then the gas enters the hollow plate 22 from the first conveying pipe 10, and then enters the spiral coil 24 from the hollow plate 22, and uses the waste heat to heat the water. When the right lower mold 5 is not needed, it is only necessary to close the third valve 19 and open the first valve 20. At this time, the hot gas discharged from the first heat exchange seat 3 will no longer enter the second heat exchange seat 4, but directly enter the switching pipe 17, enter the hollow plate 22 from the switching pipe 17, and then enter the spiral coil 24 to heat the water, realizing heat energy recovery. The setting of the one-way valve prevents the gas from backflowing.
