Description

Technical Field

[0001] This utility model relates to a motor rear cover forming mold, and in particular to a motor rear cover forming mold used in the field of motor rear cover processing. Background Technology

[0002] The motor rear cover is a protective device installed at the rear of the motor. Its main functions are: dust and water protection – preventing dust, moisture and other external pollutants from entering the motor; heat dissipation protection – helping the motor dissipate heat through heat dissipation holes or structural optimization, while preventing foreign objects from entering the motor through the heat dissipation holes; and extending lifespan – reducing the direct damage of environmental factors to the motor. When manufacturing and processing the motor rear cover, a motor rear cover molding mold is used.

[0003] The existing motor rear cover molding mold requires various demolding tools to remove the motor rear cover after it has been formed inside the mold. The demolding process is cumbersome and time-consuming, which causes great inconvenience to personnel when removing the formed motor rear cover. Utility Model Content

[0004] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that after the existing motor rear cover molding mold is formed in the mold, when it is taken out of the mold, a variety of demolding tools are used, and the demolding process is cumbersome and time-consuming.

[0005] To solve the above problems, this utility model provides a motor rear cover forming mold, including a mold box, wherein a set of symmetrically distributed support frames are fixedly connected to the surface of the mold box; A circular groove is provided on the inner bottom wall of the mold box, a circular plate is movably inserted inside the circular groove, a telescopic rod is fixedly connected to the bottom of the circular plate, and a sealing tube is sleeved on the outside of the telescopic rod. A rubber block is slidably connected inside the sealing tube, and a moving rod is fixedly connected to the bottom of the rubber block.

[0006] As a further improvement of this application, the bottom end of the support frame is fixedly connected to the same support ring, and the top of the circular plate is flush with the inner bottom wall of the mold box.

[0007] As a further improvement of this application, a reinforcing frame is fixedly connected to the inner wall of the support ring, and a plug-in slot is provided on the top of the reinforcing frame. A plug-in block that matches the plug-in slot is fixedly connected to the bottom of the moving rod.

[0008] As a further improvement of this application, the top of the reinforcing frame is provided with a pair of symmetrically distributed threaded holes, and a circular block is threadedly connected inside the threaded holes. A sleeve block is fixedly fitted on the top of the circular block.

[0009] As a further improvement of this application, in the initial state, the bottom of the socket block abuts against the top of the insertion block, and the sealing tube is under negative pressure.

[0010] As another improvement of this application, a pair of protective plates are attached to the top of the reinforcing frame, and a slider is fixedly connected to the bottom of the protective plate. A pair of symmetrically distributed sliding grooves are opened on the top of the reinforcing frame, and the slider is slidably inserted into the sliding groove.

[0011] As a further improvement to this application, the bottom of the protective plate is coated with a magnetic coating first, and the top of the reinforcing frame is coated with a magnetic coating second that is magnetically connected to the magnetic coating first.

[0012] This application has the following beneficial effects when used: 1. When using this application, after the motor rear cover is formed, before demolding it, the limiting position of the plug block needs to be released. Under the negative pressure of the sealing tube, the rubber block, telescopic rod and circular plate are moved up, thereby using the circular plate to push the motor rear cover to move up in the mold box, so that the motor rear cover is moved out of the mold box. Finally, it can be taken out of the mold box. When using this application, the demolding steps of the motor rear cover are relatively simple, time-saving and convenient, which greatly improves the demolding speed of the motor rear cover.

[0013] 2. After demolding is completed and the plug-in block is installed in the plug-in slot, a pair of protective plates should be placed on the reinforcing frame, and the slider should be inserted into the slide groove. Then, push the pair of protective plates so that they come closer to each other until they abut against each other. The protective plates cover the socket block and the plug-in block and all the connected mechanisms on them, thereby protecting these mechanisms and preventing personnel from accidentally touching the socket block and causing it to loosen, thus ensuring the stability of the plug-in block in the plug-in slot.

[0016] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0017] First implementation method: Figure 1-5 A mold for forming a motor rear cover is shown, including a mold box 1, on the surface of which a set of symmetrically distributed support frames 2 are fixedly connected; A circular groove is provided on the inner bottom wall of the mold box 1. A circular plate 4 is movably inserted into the inside of the circular groove. A telescopic rod 5 is fixedly connected to the bottom of the circular plate 4. A sealing tube 6 is sleeved on the outside of the telescopic rod 5. A rubber block 7 is slidably connected inside the sealing tube 6, and a moving rod 8 is fixedly connected to the bottom of the rubber block 7.

[0018] The bottom of a set of support frames 2 is fixedly connected to the same support ring 3, and the top of the circular plate 4 is flush with the inner bottom wall of the mold box 1.

[0019] A reinforcing frame 9 is fixedly connected to the inner wall of the support ring 3. A plug-in groove 10 is provided on the top of the reinforcing frame 9. A plug-in block 11 that matches the plug-in groove 10 is fixedly connected to the bottom of the moving rod 8.

[0020] The top of the reinforcing frame 9 has a pair of symmetrically distributed threaded holes, and a round block 12 is threadedly connected inside the threaded holes. A sleeve block 13 is fixedly fitted on the top of the round block 12.

[0021] In the initial state, the bottom of the socket block 13 abuts against the top of the plug block 11, and the sealing tube 6 is under negative pressure.

[0022] This solution can be implemented in the following way: when the motor back cover is formed inside the mold box 1, when it is taken out of the mold box 1, the sleeve block 13 needs to be rotated so that it drives the round block 12 to rotate together, so as to remove the round block 12 from the reinforcing frame 9, so that the sleeve block 13 is separated from the plug block 11, thereby releasing the limiting effect of the sleeve block 13 on the plug block 11. Then, the moving rod 8 is moved upward, causing it to push the rubber block 7 upward together inside the sealing tube 6. When the rubber block 7 moves upward, the sealing tube 6 is under negative pressure, which causes the telescopic rod 5 to push the circular plate 4 upward together. When the circular plate 4 moves upward inside the mold box 1, it will push the motor rear cover, causing it to move upward inside the mold box 1. This causes the upper end of the motor rear cover to extend a certain length from inside the mold box 1, so as to provide a point of force for personnel. Finally, personnel only need to remove it from the mold box 1. After demolding, the moving rod 8 is moved down. Under the negative pressure in the sealing tube 6, the telescopic rod 5 and all its mechanisms will move down together until the plug block 11 is moved into the plug groove 10, and the top of the circular plate 4 is flush with the inner bottom wall of the mold box 1. Then the circular block 12 is installed on the reinforcing frame 9, and the plug block 11 is limited by the sleeve block 13 to prevent it from moving out of the plug groove 10.

[0023] In summary, when using this application, after the motor rear cover is formed, before demolding it, the limiting position of the plug-in block 11 needs to be released. Under the negative pressure state of the sealing tube 6, the rubber block 7, the telescopic rod 5, and the circular plate 4 are moved upward, thereby using the circular plate 4 to push the motor rear cover upward in the mold box 1, so that the motor rear cover is moved out of the mold box 1. Finally, it can be taken out of the mold box 1. When using this application, the demolding steps of the motor rear cover are relatively simple, time-saving, and convenient, which greatly improves the demolding speed of the motor rear cover.

[0024] Second implementation method: This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below: Figure 4-6 The top of the reinforcing frame 9 is shown to be fitted with a pair of protective plates 14, and the bottom of the protective plates 14 is fixedly connected to a slider 15. The top of the reinforcing frame 9 is provided with a pair of symmetrically distributed sliding grooves 16, and the slider 15 is slidably inserted into the sliding grooves 16.

[0025] The bottom of the protective plate 14 is coated with a magnetic coating first, and the top of the reinforcing frame 9 is coated with a magnetic coating second 17 that is magnetically connected to the magnetic coating first. After the magnetic coating first and the magnetic coating second 17 are attracted together, the stability of the protective plate 14 on the reinforcing frame 9 can be improved.

[0026] This solution allows for the following steps: after demolding is completed and the plug-in block 11 is installed in the plug-in groove 10, a pair of protective plates 14 are placed on the reinforcing frame 9, and the slider 15 is inserted into the slide groove 16. Then, the pair of protective plates 14 are pushed so that they come closer to each other until they abut against each other. The protective plates 14 cover the socket block 13 and the plug-in block 11 and all the connected mechanisms on them, thereby protecting these mechanisms and preventing personnel from accidentally touching the socket block 13 and causing it to loosen, thus ensuring the stability of the plug-in block 11 in the plug-in groove 10.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
