[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown in the figure, the present invention provides a forming device for an irregularly shaped motor sealing ring, including a base plate 1 and a base 7 bolted to the top of the base plate 1. A limiting component 8 is provided on the top of the base plate 1. The limiting component 8 includes a fixing plate 81 bolted to the top of the base plate 1. A servo motor 82 is provided on the top of the fixing plate 81. A bevel gear 84 is keyed to the output shaft of the servo motor 82. A housing 83 is provided on one side of the servo motor 82. The top of the housing 83 is connected to the base 7. A circular turntable 85 is slidably connected inside the housing 83. A plurality of annular racks 86 are provided at the bottom of the circular turntable 85. The annular racks 86 mesh with the bevel gears 84. A limiting block 88 and a guide bar 87 are provided on the top of the circular turntable 85. The limiting block 88 is limited in movement by the guide bar 87.

[0026] In this embodiment, the base plate 1 and the base 7 bolted to the top of the base plate 1 are included. The top of the base plate 1 is provided with a limiting component 8 for limiting and locking the mold 6. The limiting component 8 includes a fixing plate 81 bolted to the top of the base plate 1. The fixing plate 81 of the limiting component 8 is a rectangular metal plate and is fixedly installed on the top of the base plate 1 by bolts.

[0027] A servo motor 82 is installed on the top of the fixed plate 81. The servo motor 82 is a high-precision motor that can rotate in both directions. The output shaft of the servo motor 82 is keyed to a bevel gear 84. The outer wall of the output shaft of the servo motor 82 is slidably connected to the housing 83 through a bearing seat, so that it rotates synchronously. The bevel gear 84 meshes with a ring rack 86 for transmission. A housing 83 is installed on one side of the servo motor 82. The top of the housing 83 is connected to the base 7. The housing 83 is a cylindrical metal shell, and its top is fixedly connected to the bottom of the base 7 by bolts.

[0028] A circular turntable 85 is slidably connected inside the housing 83. The inside of the housing 83 is a cylindrical cavity, and the circular turntable 85 is slidably connected inside the cavity. The outer diameter of the circular turntable 85 is adapted to the diameter of the inner cavity of the housing 83, and it can slide circumferentially inside the inner cavity of the housing 83.

[0029] The bottom of the circular turntable 85 is provided with several annular racks 86, which mesh with bevel gears 84. When the servo motor 82 is started, its output shaft drives the bevel gears 84 to rotate, and the circular turntable 85 is driven to slide circumferentially within the housing 83 through the gear meshing action.

[0030] The top of the circular turntable 85 is provided with a limiting block 88 and a guide bar 87. The limiting block 88 is limited by the guide bar 87. The guide bar 87 is a ring-shaped structure and is welded and fixed to the top surface of the circular turntable 85. The limiting block 88 is a rectangular block structure, and its bottom is provided with a sliding groove that matches the guide bar 87. The limiting block 88 slides with the guide bar 87 through the sliding groove, thereby enabling the limiting block 88 to move linearly under the restriction of the guide bar 87.

[0031] When the circular turntable 85 rotates, the limiting block 88 moves in a circle along with the circular turntable 85, and also slides in a straight line along the guide bar 87 due to the restriction of the guide bar 87.

[0032] It should be noted that side plates 2 are provided on both sides of the base plate 1. The base plate 1 is a rectangular metal plate with anti-slip rubber pads at the four corners of its bottom for stability. A top plate 3 is provided on the top of the side plates 2. The side plates 2 are welded vertically upward from both sides of the base plate 1. The side plates 2 are rectangular metal plates, and their height is determined according to the overall design of the equipment. The top plates 3 are welded horizontally to the top of both side plates 2. The top plates 3 are rectangular metal plates and are set parallel to the base plate 1, thus forming a stable frame structure.

[0033] It should be noted that the top of the top plate 3 is provided with an extrusion assembly 4. The extrusion assembly 4 includes a hydraulic telescopic rod 41 bolted to the top of the top plate 3. The hydraulic telescopic rod 41 is a double-acting hydraulic cylinder. Its output shaft passes vertically downward through the top plate 3 and extends to the bottom of the top plate 3. The output shaft of the hydraulic telescopic rod 41 is fixedly connected to a connecting block 42. The connecting block 42 is a rectangular metal block. Its bottom is fixedly connected to a pressure plate 43 by bolts. The pressure plate 43 is a rectangular metal plate. Its size is designed according to the size of the mold 6 and is used to apply pressure to the mold 6.

[0034] The bottom of the connecting block 42 is bolted to a pressure plate 43. Guide rods 44 are provided on both sides of the pressure plate 43. Limit seats 45 are inserted into both sides of the top plate 3. The guide rods 44 are cylindrical metal rods, and their top ends are respectively inserted into the limit seats 45 provided on both sides of the top plate 3. The guide rods 44 are connected to the top plate 3 through the limit seats 45. The limit seats 45 are cylindrical metal seats, which are fixedly installed on both sides of the bottom of the top plate 3 by bolts. Cylindrical through holes adapted to the guide rods 44 are opened inside them. The guide rods 44 can slide up and down in the through holes of the limit seats 45.

[0035] When the output shaft of the hydraulic telescopic rod 41 extends or retracts, it drives the pressure plate 43 to move up and down. The guide rod 44 slides within the limit seat 45 to ensure that the pressure plate 43 moves smoothly and to prevent the pressure plate 43 from tilting during the movement.

[0036] It is understandable that the base 7 has a mold 6 on its top and a circular hole at its bottom. The mold 6 is locked to the limiting block 88 through the circular hole. When the limiting block 88 rotates to a specific position, it can be inserted into the circular hole at the bottom of the mold 6 to achieve the locking of the mold 6 and the base 7.

[0037] It is understandable that a pressing component 5 is provided on the top of the base 7 for further fixing the mold 6. The pressing component 5 includes a fixing seat 51 bolted to both sides of the top of the base 7. The fixing seat 51 of the pressing component 5 is an L-shaped metal seat, which is fixedly installed on both sides of the top of the base 7 by bolts.

[0038] A connecting rod 52 is rotatably connected between the fixed seats 51. The two fixed seats 51 are rotatably connected by a bearing. The connecting rod 52 is a cylindrical metal rod. Its two ends are respectively interference-fitted with the inner ring of the bearing on the fixed seat 51. A rotating seat 53 is sleeved on the middle of the outer wall of the connecting rod 52.

[0039] A rotating seat 53 is sleeved on the outer wall of the connecting rod 52. The rotating seat 53 is a cylindrical metal sleeve, and its inner wall is interference-fitted with the outer wall of the connecting rod 52. It can rotate together with the connecting rod 52. A cover plate 54 is bolted to one side of the rotating seat 53. The cover plate 54 is a rectangular metal plate, and its length and width are designed according to the size of the mold 6. A locking block 55 is provided on one side of the cover plate 54. The locking block 55 is a metal block and is fixedly connected to the cover plate 54 by bolts.

[0040] By rotating the locking block 55, when the connecting rod 52 is rotated, the rotating seat 53 rotates accordingly, causing the cover plate 54 to make a circular motion around the connecting rod 52, thereby realizing the opening and closing operation of the cover plate 54 on the mold 6.

[0041] In some embodiments, a heating component 9 is provided on the top side of the base plate 1. The heating component 9 is electrically connected to the cover plate 54. The heating component 9 is an electric heating device and is fixedly installed on the base plate 1 by bolts. The heating component 9 includes a heating controller and a heating element.

[0042] It should be noted that the heating control module is controlled automatically by a controller. The controller circuit can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0043] Working steps: 1. Start the limiting component 8, rotate the limiting block 88 to the unlock position, place the selected mold 6 on the top of the base 7, and align the circular hole at the bottom of the mold 6 with the limiting block 88.

[0044] Second, restart the limit component 8 and rotate the servo motor 82 in the opposite direction so that the limit block 88 slides along the guide bar 87 and is embedded in the bottom circular hole of the mold 6, thus completing the limit locking of the mold 6.

[0045] 3. Depending on the material of the sealing ring, such as rubber or plastic, fill the pre-treated raw material evenly into the cavity of mold 6.

[0046] Fourth, operate the pressing component 5, rotate the locking block 55 to make the connecting rod 52 drive the rotating seat 53 and the cover plate 54 to rotate, so that the cover plate 54 further fixes the mold 6.

[0047] 5. Set the temperature parameters of the heating component 9 through the control system to ensure that the mold 6 reaches the appropriate molding temperature;

[0048] 6. Start the hydraulic telescopic rod 41. The output shaft of the hydraulic telescopic rod 41 pushes the connecting block 42 and the pressure plate 43 to move downward. The guide rod 44 slides in the limit seat 45 to ensure that the pressure plate 43 presses down smoothly and applies pressure to the mold 6. At the same time, the heating component 9 heats the mold 6 so that the raw material is formed under high temperature and high pressure.

[0049] 7. Maintain constant pressure on hydraulic telescopic rod 41 and hold the pressure for the set time to ensure the sealing ring is fully cured and formed;

[0050] 8. After the pressure holding time is over, start the extrusion assembly 4 to lift the pressure plate 43 to release the fixation of the pressing assembly 5. Then, flip up the pressing assembly 5 through the locking block 55 and take out the formed irregular motor sealing ring.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
