[0002] The housing of micro motor parts is an important component of micro motors, mainly used to protect the internal parts of the motor, serve as a support for the motor, dissipate heat, and provide electromagnetic shielding. The molding molds used for micro motor parts housings can ensure product quality, improve production efficiency, reduce production costs, and achieve specific performance requirements. Traditional molding molds for micro motor parts housings have limited design flexibility, material performance limitations, difficulty in adapting to new processes, high maintenance costs, and limited mold opening and closing speeds. To meet the production requirements of modern micro motor parts housings, new molding molds for micro motor parts housings are used.

[0003] In existing technology, when removing the outer shell, the user needs to place their hand between the upper and lower molds, which can easily cause personal injury to the user. In addition, when removing the outer shell, the outer shell is too tightly bonded to the lower mold, which requires the use of tools to remove the mold and may cause damage to the outer shell. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a molding die for the housing of a micro motor part. It aims to solve the problems that when removing the housing, the user needs to place their hand between the upper and lower molds, which can easily cause personal injury to the user. In addition, when removing the housing, the housing is too tightly bonded to the lower mold, which requires the use of tools to remove the mold and may cause damage to the housing.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a molding die for a micro motor part shell, including a lower die 1, a slider 11 fixedly connected to the lower surface of the lower die 1, a top block 12 slidably connected to the inner wall of the slider 11, the outer wall of the top block 12 slidably connected to the inner wall of the lower die 1, a first spring rod 13 fixedly connected to the lower surface of the top block 12, a moving block 14 fixedly connected to the lower surface of the first spring rod 13, a driving block 15 fixedly connected to the inner wall of the moving block 14, a limiting plate 16 slidably connected to the outer wall of the driving block 15, a handle 17 fixedly connected to the front outer wall of the slider 11, and a molding component provided on the outer wall of the limiting plate 16 for molding the part shell;

[0025] Specifically, pulling the handle 17 causes the slider 11 to slide on the inner wall of the molding machine 2, causing the lower mold 1 to move simultaneously. The lower mold 1 and the slider 11 cause the top block 12 to move, which in turn causes the first spring rod 13 to move the moving block 14. The moving block 14 then causes the drive block 15 to move. Under the action of the limiting plate 16, the top block 12 moves upward. This not only prevents the hand from being pinched when removing the outer shell, but also achieves the effect of automatic demolding.

[0026] Reference Figure 1 and Figure 3The molding assembly includes a molding device 2, the inner wall of the molding device 2 is fixedly connected to the outer wall of the limiting plate 16, the inner wall of the molding device 2 is slidably connected to the outer wall of the slider 11, the inner wall of the molding device 2 is slidably connected to the outer wall of the moving block 14, an upper mold 21 is provided inside the molding device 2, and a fixing component is provided inside the molding device 2 for fixing the upper mold 21.

[0027] Specifically, by pressing down the forming device 2 with push rod 37, the upper mold 21 and the lower mold 1 are connected, thereby achieving the effect of quickly completing the forming operation of the shell of the micro motor parts.

[0028] Reference Figure 1 and Figure 4 The fixing assembly includes a lead screw 3, the outer wall of which is rotatably connected to the inner wall of the forming device 2. A clamping plate 31 is threadedly connected to the outer wall of the lead screw 3, and the outer wall of the clamping plate 31 is slidably connected to the outer wall of the upper mold 21. A fixing block 32 is fixedly connected to the outer wall of the clamping plate 31, and the outer wall of the fixing block 32 is slidably connected to the inner wall of the upper mold 21. An ejector block 33 is threadedly connected to the outer wall of the lead screw 3. A limit groove is formed in the inner wall of the forming device 2, and the outer wall of the ejector block 33 is slidably connected to the inner wall of the limit groove. A sliding block 34 is slidably connected to the inner wall of the molding machine 2. The outer wall of the sliding block 34 is slidably connected to the inner wall of the molding machine 2. A sliding groove is provided on the inner wall of the molding machine 2. The outer wall of the sliding block 34 is slidably connected to the inner wall of the sliding groove. A second spring rod 35 is provided on the outer wall of the sliding block 34. The outer wall of the second spring rod 35 is provided on the inner wall of the molding machine 2. A gripper 36 is fixedly connected to the lower surface of the sliding block 34. The outer wall of the gripper 36 is slidably connected to the inner wall of the upper mold 21. A push rod 37 is fixedly connected to the upper surface of the molding machine 2.

[0029] Specifically, rotating the lead screw 3 drives the clamping plate 31 and the fixing block 32 to move, so that the upper mold 21 is clamped. At the same time, the push block 33 is moved, thereby pushing the sliding block 34 to move, causing the spring part of the second spring rod 35 to undergo elastic deformation. The sliding block 34 drives the gripper 36 to move, so that the gripper 36 clamps the upper mold 21 and does not affect the operation of the upper mold 21 and the lower mold 1 during the molding operation. This achieves the effect of clamping the upper mold 21, and also provides support when installing and disassembling the upper mold 21, making installation easier.

[0030] Working principle: When the mold is needed, rotating the lead screw 3 moves the clamping plate 31 and the fixing block 32 outward, causing the ejector block 33 to move backward. Simultaneously, the spring portion of the second spring rod 35 undergoes elastic deformation, pushing the sliding block 34 and causing the gripper 36 to move inward. This clamps the upper mold 21, supporting and centering it. Then, rotating the lead screw 3 in the opposite direction moves the sliding block 34 outward, and the clamping plate 31 and the fixing block 32 inward, thus clamping the upper mold 21. This achieves the effect of clamping the upper mold 21 and provides support for its installation and removal, facilitating installation. Then, push rod 37 pushes the molding device 2 to press together, connecting the upper mold 21 and the lower mold 1 for molding. After completion, pull handle 17 to drive slider 11 to slide on the inner wall of molding device 2, so that lower mold 1 is moved out at the same time. Lower mold 1 and slider 11 drive the first spring rod 13 to move, so that moving block 14 moves while driving drive block 15 to slide on the inner wall of limit plate 16. This mold can not only prevent the hand from being pinched when removing the shell, but also achieve the effect of automatic demolding. On the other hand, it can achieve the effect of clamping upper mold 21, and also provide support when installing and disassembling upper mold 21, which is convenient for installation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
