Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figures 1-6A casting mold for an electric motor housing includes a base 1. Four fixing frames 2 are symmetrically distributed on the upper part of the base 1. Hydraulic rods 3 are fixedly installed on the upper part of the fixing frames 2. A mold 4 is fixedly installed between the telescopic ends of two hydraulic rods 3 on the same side. The mold 4 is located on the upper part of the base 1. A sliding groove 5 is symmetrically formed on the top of the base 1. Ribs 6 are symmetrically fixedly installed on the bottom of the mold 4, fitting into the sliding grooves 5. A groove 7 is formed at the bottom of the ribs 6. A cavity 8 is formed at the bottom of the sliding groove 5. Two electric actuators 9 are symmetrically distributed on the left and right. A lifting plate 10 is fixedly installed at the telescopic end of the electric actuator 9. A limit block 11 is fixedly installed on the upper part of the lifting plate 10. Position block 11 is movably sleeved on the top of cavity 8 and engaged with groove 7. The hydraulic rod 3 is activated so that its telescopic end pushes mold 4. The bottom rib 6 of mold 4 engages with the sliding groove 5 on base 1, allowing mold 4 to slide on the upper part of base 1. This helps prevent deviation of mold 4 during movement. When the left and right molds 4 are merged, groove 7 is located directly above cavity 8. The electric push rod 9 is activated so that its telescopic end drives lifting plate 10 to rise in cavity 8, allowing position block 11 to engage with groove 7, locking the position of the two molds 4. This ensures that the two molds 4 fit tightly together, preventing leakage during pouring, reducing safety hazards during operation, and improving the stability of the device during operation.

[0021] A second slide groove 12 is formed on the top of the base 1 between two slide grooves 5. A connecting groove 13 is fixedly installed on the bottom of the mold 4 between two ribs 6. The connecting groove 13 fits into the second slide groove 12. Three rollers 14 are evenly and movably sleeved in the inner cavity of the connecting groove 13 via shafts and are in contact with the bottom of the second slide groove 12. The fit between the connecting groove 13 and the second slide groove 12 allows the rollers 14 to slide in the second slide groove 12, providing guidance and facilitating flexible movement of the mold 4 while avoiding excessive resistance to movement. A slot 15 is formed on the top of the base 1 between the two molds 4. The slot 15 is fixedly connected to the first slide groove 5 and the second slide groove 12 respectively. Injection ports 16 are formed on the upper part of the two molds 4 respectively. Injection is poured into the inner cavity formed by the merging of the two molds 4 through the injection ports 16. Air is poured from the other injection port 1. The material can be poured through two injection ports 16, allowing it to be evenly distributed inside the mold 4. The sloping structure of the injection ports 16 allows the material to slowly enter the mold 4 cavity, avoiding the generation of a large number of air bubbles during the pouring process. A water inlet 17 is fixedly installed at the front of the mold 4, and a drain outlet 18 is fixedly installed at the front of the mold 4 and directly below the water inlet 17. A condenser pipe 19 is fixedly installed between the water inlet 17 and the drain outlet 18 and inside the mold 4. After pouring, a water pipe is connected to the water inlet 17, allowing the condensate to enter the condenser pipe 19 through the water inlet 17 to cool the formed motor housing. The condensate, after absorbing heat, is discharged from the drain outlet 18. By setting cooling mechanisms in the left and right molds 4 respectively, the cooling efficiency of the device is improved, which is conducive to improving the production efficiency of the device.

[0022] Working principle: Activating hydraulic rod 3 causes its telescopic end to push mold 4. The bottom ribs 6 of mold 4 engage with the sliding groove 5 on base 1, allowing mold 4 to slide on the upper part of base 1. Simultaneously, connecting groove 13 engages with sliding groove 12, allowing roller 14 to slide within sliding groove 12, facilitating flexible movement of mold 4. When the left and right molds 4 merge, groove 7 is directly above cavity 8. At this time, activating electric actuator 9 causes its telescopic end to lift lifting plate 10 within cavity 8, causing limit block 11 to engage with groove 7. The slots 7 are interlocked to lock the positions of the two molds 4. The mold is poured into the cavity formed by the two molds 4 through the injection port 16. Air is discharged from the other injection port 16. After pouring, the water inlet 17 is connected to a water pipe so that the condensate enters the condenser pipe 19 through the water inlet 17 to cool the formed motor housing. The condensate that has absorbed heat is discharged from the drain port 18. After cooling, the left and right molds 4 are separated so that the formed motor housing falls into the slot 15 for easy removal by the staff.
