In the production process of the plastic packaging rotor, a rotor plastic packaging mold is needed to process it more conveniently.

[0004] The rotor plastic packaging mold on the market at present mainly consists of a mold frame, a mold core, a mold core and a guide rod. When in use, the rotor is placed in the mold core, the mold core is pressed tightly by the hydraulic rod, and the mold core is injection molded to complete the plastic packaging of the rotor. However, when in use, the rotor is attracted by the insert when placed in the mold core due to its strong magnetism, resulting in uneven plastic packaging on the outside of the rotor. The existing technology adds a positioning pin in the mold core, so that the rotor can always be in the correct position in the device during injection molding. However, the hydraulic rod needs to be used to extrude the mold core during injection molding, which can cause damage to the mouth of the mold core, and the repair time is long. The existing technology grinds the surface of the mold core to repair the mold core more quickly and conveniently. However, due to the limited space inside the mold core, the size tolerance of the mold core will approach the critical value after multiple grinding, resulting in that the mold core cannot be used, and the practicability of the device is reduced, which cannot meet the needs of the user.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1 , Figure 3 and Figure 4 This invention provides a rotor plastic coating mold that is easy to maintain, including a base 1, an outer shell 5 on the upper side of the base 1, an adjustment mechanism 2 on the top of the outer shell 5 for easy maintenance of the mold, a disassembly mechanism 3 on the outer side of the outer shell 5 for easy disassembly and maintenance of the mold, and a lifting mechanism 4 on the top of the base 1 for easy ejection of the product. The adjusting mechanism 2 includes a mold core 21, which is located on the top of the outer shell 5. Injection cavities 28 are formed around the top of the mold core 21. An adjusting block 22 is slidably connected to the center of the inner side of each injection cavity 28, allowing it to slide within the cavity. A movable core 23 is located on the top of the adjusting block 22. A fixing block 24 is fixedly connected to the bottom inner side of the injection cavity 28, and a pin 25 is fixedly connected to the top of the fixing block 24. The pin 25 prevents the rotor from moving. The top of the pin 25 passes through the adjusting block 22 and the movable core 23. A lifting assembly 26 is located inside the outer shell 5, and the lifting assembly 26 includes an inner cavity 261. 261 is located inside the outer shell 5. A bidirectional threaded rod 262 is rotatably connected to the lower middle part of the inner side of the inner cavity 261. The rear end of the bidirectional threaded rod 262 passes through the outer shell 5. T-shaped blocks 263 are threadedly connected to the front and rear sides of the outer wall of the bidirectional threaded rod 262. Rotation of the bidirectional threaded rod 262 will drive the T-shaped blocks 263 to move. A support block 264 is provided in the upper middle part of the inner side of the inner cavity 261. The T-shaped blocks 263 are in contact with the support block 264. When the T-shaped blocks 263 move, the support block 264 will move downward. The outer side of the support block 264 passes through the outer shell 5 and is fixedly connected to the adjusting block 22. The support block 264 will drive the adjusting block 22 to move. Specifically, when the mold core 21 of the device mold is damaged and needs repair, the mold core 21 is first removed from the device, and the surface of the mold core 21 is directly ground. After grinding, the bidirectional threaded rod 262 is rotated. When the bidirectional threaded rod 262 rotates, it drives the T-blocks 263 on both sides to move towards the middle. As the T-blocks 263 move, the support block 264 moves downward. The downward movement of the support block 264 further drives the adjusting block 22 to move downward. Therefore, the movable core 23 also moves downward. In this way, after the surface of the mold core 21 is ground, the size of the injection space can remain unchanged, which improves the practicality of the device and can meet the needs of users.

[0023] Reference Figure 2 , Figure 3 and Figure 5The disassembly mechanism 3 includes a U-shaped plate 31, which is fixedly connected to the outside of the outer shell 5. A double-threaded rod 32 is rotatably connected to both the left and right sides of the inside of the U-shaped plate 31. A slider 33 is threadedly connected to both the front and rear sides of the outer wall of the double-threaded rod 32. Rotation of the double-threaded rod 32 causes the slider 33 to move. A connecting rod 34 is rotatably connected to one side of the slider 33. One end of the connecting rod 34 passes through the outer shell 5 and is fixedly connected to a connecting seat 35. When the slider 33 moves, the connecting rod 34 can drive the connecting seat 35 to move. A locking block 36 is fixedly connected to one side of the connecting seat 35, causing the locking block 36 to move. Slots 37 are provided on both the left and right sides of the mold core 21, and the locking block 36 interacts with the slots 37. When the locking block 36 disengages from the locking slot 37, the mold core 21 can be disassembled. A transmission assembly 38 is provided on the rear inner side of the U-shaped plate 31. The transmission assembly 38 includes a rotating rod 381, which is rotatably connected to the rear inner side of the U-shaped plate 31. The right end of the rotating rod 381 passes through the U-shaped plate 31. Both the left and right sides of the outer wall of the rotating rod 381 are fixedly connected to the driving bevel gear 382. The rotating rod 381 will drive the driving bevel gear 382 to rotate. The rear end of the bidirectional threaded rod 32 is fixedly connected to the driven bevel gear 383. The driven bevel gear 383 meshes with the driving bevel gear 382. When the driving bevel gear 382 rotates, the driven bevel gear 383 will drive the bidirectional threaded rod 32 to rotate. Specifically, when the mold core 21 needs to be disassembled and repaired, first rotate the rotating rod 381 to drive the driving bevel gear 382 to rotate. Since the driven bevel gear 383 meshes with the driving bevel gear 382, ​​the driven bevel gear 383 will also rotate, thereby driving the bidirectional threaded rod 32 to rotate. The bidirectional threaded rod 32 will drive the slider 33 to move. During the movement of the slider 33, through the transmission action of the connecting rod 34, the connecting seat 35 can be pushed to move. The connecting seat 35 will drive the locking block 36 to move together, so that the locking block 36 is disengaged from the locking state of the locking groove 37, and the mold core 21 can be disassembled more conveniently, reducing the workload of the staff.

[0024] Reference Figure 6 , Figure 7 and Figure 8The lifting mechanism 4 includes a fixed plate 41, which is fixedly connected to the top of the base 1. A support plate 42 is provided on the top of the fixed plate 41. A groove 43 is provided on the rear side of the top of the fixed plate 41. A telescopic rod 44 is fixedly connected to the rear side of the groove 43. A mounting seat 45 is fixedly connected to the front end of the telescopic rod 44. The telescopic rod 44 will push the mounting seat 45 to move. A support rod 46 is rotatably connected to the front side of the mounting seat 45. A mounting seat 47 is rotatably connected to the top of the support rod 46. The mounting seat 45 can push the mounting seat 47 to move through the support rod 46. The top of the mounting seat 47 is fixedly connected to the support plate 42. Pins 48 are provided around the top of the support plate 42. The top of the plate 42 passes through the outer shell 5, the fixing block 24, the adjusting block 22 and the movable core 23 in sequence. The plate 42 will drive the ejector pin 48 to rise, thereby ejecting the rotor. The rear side of the top of the plate 42 is provided with a shock-absorbing component 49. The shock-absorbing component 49 includes a fixing rod 491. The two fixing rods 491 are fixedly connected to the left and right sides of the top rear end of the plate 42. The outer side of the fixing rod 491 is provided with a shock-absorbing spring 492. The shock-absorbing spring 492 can provide shock absorption for the mold core 21. The lifting mechanism 4 also includes a guide column 410. The two guide columns 410 are fixedly connected to the left and right sides of the top of the fixing plate 41 respectively. The top of the guide column 410 passes through the plate 42. The guide column 410 can provide guidance for the movement of the plate 42. Specifically, after the injection molding process is completed, the electric telescopic rod 44 is activated, pushing the mounting base 45 forward. When the mounting base 45 moves, the support rod 46 pushes the mounting base 47 upward, further causing the support plate 42 to move upward. The rise of the support plate 42 then drives the ejector pin 48 to rise. The rising action of the ejector pin 48 ejects the rotor that has been processed in the injection cavity 28, thereby simplifying the rotor discharge process. In addition, during the injection molding operation, the shock-absorbing spring 492 can provide shock absorption protection for the mold core 21, reducing damage to the mold core 21 and improving the ease of use of the device.

[0025] Reference Figure 1 , Figure 6 and Figure 7 The base 1 has a mold frame 6 on the top left and right sides. Multiple plug rods 7 are fixedly connected at equal intervals on the top left and right sides of the base 1. The top of the plug rods 7 passes through the mold frame 6. The adjustment mechanism 2 also includes a sleeve 27. Multiple sleeves 27 are fixedly connected to the top four corners of the outer shell 5. The bottom of the sleeve 27 passes through the outer shell 5. The sleeve 27 can provide positioning for the movement of the upper mold. Specifically, the mold frame 6 can support the outer shell 5, and the sleeve 27 can guide the mold closing operation.

[0026] Reference Figure 6 and Figure 7The lifting mechanism 4 also includes a fixed plate 41 with positioning pins 411 fixedly connected to the top of the four sides, and positioning holes 412 are opened on the bottom of the outer shell 5. The top of the positioning pin 411 passes through the support plate 42 and engages with the positioning hole 412. The positioning pin 411 can keep the installation position of the outer shell 5 accurate. Specifically, the positioning hole 412 and the positioning pin 411 at the bottom of the outer casing 5 cooperate with each other to ensure that the installation position of the outer casing 5 is accurate.

[0027] Working principle: When the mold core 21 of this device is damaged and needs repair, the mold core 21 is first disassembled and the surface of the mold core 21 is ground directly. Then, the bidirectional threaded rod 262 is rotated. When the bidirectional threaded rod 262 rotates, it will drive the T-blocks 263 on both sides to move towards the middle. When the T-blocks 263 move, the support block 264 will move downward. When the support block 264 moves downward, it will drive the adjusting block 22 to move downward. The movable core 23 will move downward, so that the size of the injection space will not change after the surface of the mold core 21 is ground. Furthermore, when it is necessary to disassemble and repair the mold core 21, rotating the rotating rod 381 will drive the driving bevel gear 382 to rotate. Since the driven bevel gear 383 meshes with the driving bevel gear 382, ​​the driven bevel gear 383 will drive the bidirectional threaded rod 32 to rotate, thereby driving the slider 33 to move. When the slider 33 moves, it can push the connecting seat 35 to move through the connecting rod 34. The connecting seat 35 will then drive the locking block 36 to move, so that the locking block 36 disengages from the locking groove 37, making it easier to disassemble the mold core 21. Furthermore, after injection molding is completed, the electric telescopic rod 44 will be activated, pushing the mounting base 45 forward. When the mounting base 45 moves forward, the support rod 46 can push the mounting base 47 upward, thereby driving the support plate 42 upward. The support plate 42 will then drive the ejector pin 48 to rise. The rising ejector pin 48 will push out the rotor that has been processed inside the injection cavity 28, facilitating the rotor's discharge. During injection molding, the damping spring 492 can provide shock absorption for the mold core 21, reducing damage to the mold core 21.
