Description

Technical Field

[0001] This utility model relates to the field of motor housing production technology, and more specifically, it relates to a production mold for motor housing. Background Technology

[0002] When using a production mold during the production of motors, molten iron is poured directly into the interior of the production mold body. After the molten iron cools, one side of the mold is removed, allowing the motor housing to be taken out of the interior of the production mold body. This process ensures the proper production of the motor housing.

[0003] A search revealed that Chinese utility model patent application number CN202421721551.2 discloses a production mold for an electric motor housing, comprising: a demolding mechanism, a fixing mechanism at the bottom of the demolding mechanism, the demolding mechanism including a mold body, a casting cavity on the inner wall of the mold body, and a bottom ring at the bottom end of the inner wall of the casting cavity.

[0004] When in use, the lead screw rotates, causing it to move from its original position. During this process, external force is continuously applied to the movable arm, gradually transforming it from an inclined position to a horizontal parallel position. During this transformation, the connecting arm moves, and the triangular plate moves under the pressure of the connecting arm. The bottom ring moves vertically upward under the external force, pushing a portion of the shaped motor housing out of the casting cavity. Then, people remove the portion of the motor housing. At this time, the mold and the outside of the motor housing are still at a high temperature. When people remove the motor housing from the mold, their bodies are in contact with the mold and the motor housing, which can easily cause burns to the workers. Utility Model Content

[0030] Please see Figures 1-5A production mold for an electric motor housing includes a fixed platform 1. A fixed base 2 is fixedly connected to the rear left side of the top of the fixed platform 1. A first fixed plate 3 is fixedly connected to the left front end of the fixed base 2. A first mold 4 is mounted on the first fixed plate 3. The first mold 4 has two mold slots 5. A second fixed plate 6 is fixedly connected to the right front end of the fixed base 2. A first electric cylinder 7 is fixedly connected to the second fixed plate 6. An installation plate 8 is fixedly connected to the telescopic end of the first electric cylinder 7. Two horizontal plates 28 are fixedly connected to the side end of the installation plate 8. Both horizontal plates 28 slide in cooperation with the second fixed plate 6. A protective box 29 is fixedly connected to the side end of the second fixed plate 6. The protective box 29 is fitted over the two horizontal plates 28, providing support for the installation base and the second mold 9. The protective box 29 also provides protection against injury to workers during the movement of the horizontal plates 28 with the installation plate 8. The mounting plate 8 is equipped with a second mold 9, which has two punches 10. Both mold slots 5 have a first ejection mechanism, and the second mold 9 has a second ejection mechanism. A triangular base 11 is fixedly connected to the top of the fixed platform 1, below the first mold 4 and the second mold 9. Baffles 25 are fixedly connected to the middle and front of the top of the triangular base 11, dividing it into two guide channels 26. The motor housing slides down the fixed platform 1 away from the first mold 4 and the second mold 9 via the guide channels 26, while also preventing collisions between the two motor housings. High-temperature resistant rubber pads 27 are fixedly connected to the bottom of both guide channels 26 to increase their flexibility and prevent damage from impacts when the motor housing falls onto the triangular base 11.

[0031] Specifically, since both the first mold 4 and the second mold 9 are arranged horizontally, the motor housing poured from inside the first mold 4 and the second mold 9 will fall onto the triangular base 11. The motor housing will slide down onto the fixed platform 1 on the side away from the first mold 4 and the second mold 9 through the triangular base 11. This prevents people from removing the motor housing from the first mold 4 and the second mold 9, prevents people's bodies from coming into contact with the first mold 4 and the second mold 9, and prevents people's bodies from being burned.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5The first ejection mechanism includes a second electric cylinder 12. A first groove 13 is provided inside the mold groove 5, and a top plate 14 is provided inside the first groove 13. The second electric cylinder 12 is fixedly mounted on the first mold 4. The telescopic rod of the second electric cylinder 12 is fixedly connected to the side end of the top plate 14 to facilitate ejecting the motor housing inside the mold groove 5. The second ejection mechanism includes a third electric cylinder 15. Annular grooves 16 are provided on the second mold 9 outside the two punches 10. The two annular grooves 16 are connected by a connecting groove 17. Each of the 6 has a top ring 18 inside, and a connecting plate 19 is fixedly connected between the two top rings 18. The connecting plate 19 is located inside the connecting groove 17. The third electric cylinder 15 is fixedly installed on the second mold 9. The telescopic rod of the third electric cylinder 15 is fixedly connected to the side end of the connecting plate 19, which facilitates pushing down the motor housing outside the punch 10. The first fixing plate 3 is provided with through grooves 30 at the positions corresponding to the two second electric cylinders 12 and the mounting plate 8 is provided with the positions corresponding to the third electric cylinder 15, which facilitates the passage of the second electric cylinder 12 and the third electric cylinder 15.

[0033] Specifically, if the motor housing is stuck inside the mold groove 5, the second electric cylinder 12 drives the top plate 14 to move, and the top plate 14 pushes the motor housing out of the mold groove 5. If the motor housing is stuck outside the punch 10, the third electric cylinder 15 pushes the connecting plate 19 and the two top rings 18 to move, and the top rings 18 push the motor housing outside the punch 10 down, thus avoiding the need for people to remove the motor housing manually.

[0034] Please see Figure 1 , Figure 2 and Figure 4 The mounting platform 1 is provided with a mounting slot 20, and a cooling box 21 is fixedly connected inside the mounting slot 20. The bottom side of the cooling box 21 is connected to an inlet and outlet pipe 22, and a valve 23 is installed on the inlet and outlet pipe 22. The top side of the cooling box 21 is connected to an overflow pipe 24, which facilitates cooling and temperature reduction of the motor housing.

[0035] Specifically, the motor housing that rolls off the triangular base 11 rolls into the cooling box 21, where the water inside the cooling box 21 cools the motor housing. Then, the staff removes the cooled motor housing, thus avoiding contact between people and the hot motor housing and preventing burns.

[0036] In summary, when using the overall equipment:

[0037] The first electric cylinder 7 pushes the second mold 9 to move, bringing the sides of the first mold 4 and the second mold 9 closer together. At this time, the two punches 10 are respectively inserted into the two mold slots 5. Then, the molten material is poured through the pouring port on the first mold 4 into the middle of the first mold 4 and the second mold 9. After the motor housing inside the first mold 4 and the second mold 9 cools and solidifies, the first electric cylinder 7 pulls the mounting plate 8 and the second mold 9 to move away from the first mold 4, so that the second mold 9 moves to the farthest position. If the motor housing is stuck inside the mold slot 5, the second electric cylinder 12 drives the top plate 14 to move, and the top plate 14 pushes out the motor housing inside the mold slot 5. If the motor housing is stuck in the punch 10, the second electric cylinder 12 drives the top plate 14 to move, and the top plate 14 pushes out the motor housing inside the mold slot 5. Outside of the punch 10, the connecting plate 19 and the two top rings 18 are moved by the third electric cylinder 15. The top rings 18 push down the motor housing outside the punch 10. The motor housing will fall onto the triangular seat 11 and roll down into the cooling box 21. At the same time, it is connected to the external water supply equipment through the inlet and outlet pipes 22. Water is transported to the inside of the cooling box 21 through the water supply equipment. The water inside the cooling box 21 cools down the motor housing. After the motor housing is cooled down, the worker can take the cooled motor housing out of the cooling box 21. When the water inside the cooling box 21 reaches the overflow pipe 24, the water inside the cooling box 21 is discharged through the overflow pipe 24.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
