All other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0030] Embodiment 1, please refer to Figure 1 - Figure 12 , the present invention provides a technical solution for a rapid core-pulling mechanism for precision impeller injection molding: The rapid core-pulling mechanism for impeller injection molding includes: a mounting seat 1, the outer wall of the middle of the top of the mounting seat 1 is rotationally connected with a driving seat 2, the outer wall of the top of the driving seat 2 is provided with a slot hole, the outer wall of the top of the mounting seat 1 is provided with a square groove 11, the inner part of the mounting seat 1 located in the middle of the driving seat 2 at the top is provided with a circular groove 12, a transmission mechanism is arranged inside the square groove 11, a core-pulling mechanism is arranged on one side of the transmission mechanism, the outer wall of the rotating rod 31 is rotationally connected with a fixed plate 73, the outer wall of the rotating rod 31 is movably connected with a half gear 7, the outer wall of the top of the half gear 7 is meshed and connected with the outer wall of the bottom of the second tooth seat 34, a fixed rod 72 is fixedly connected to the outer wall of one side of the half gear 7, a return spring 74 is fixedly connected to the outer wall of one side of the half gear 7, the inner part of the return spring 74 is movably sleeved on the outer wall of the rotating rod 31, one end of the return spring 74 is fixedly connected to the outer wall of one side of the fixed plate 73, a clamping groove is provided on the outer wall of the top of the fixed plate 73, sliding rods are fixedly connected to the outer walls of both sides of the half gear 7, and the outer walls of the sliding rods are slidably connected with slide grooves 71, and the slide grooves 71 are arranged on both sides of the inner wall of the square groove 11.

[0031] The half gear 7 leaves the bottom of the second gear holder 34, thereby releasing the limit on the second gear holder 34. The cooperation between the half gear 7 and the second gear holder 34 can fix the transmission mechanism when the transmission mechanism is not in use, thereby preventing the driving seat 2 from moving in the working state, and correspondingly increasing the stability of the driving seat 2, thereby increasing the stability of the core pulling mechanism when working.

[0032] By cooperating the slide bars and the slide grooves 71 on both sides of the half gear 7, the stability of the half gear 7 can be increased when the half gear 7 is fixed to the tooth seat 2 34, thereby avoiding rotation of the half gear 7 when the half gear 7 is fixed to the tooth seat 2 34, and correspondingly increasing the stability of the half gear 7, further improving the fixing effect of the half gear 7.

[0033] Embodiment 2, on the basis of embodiment 1, the transmission mechanism includes a motor 3, the outer wall of the motor 3 is fixedly connected to one side of the inner wall of the square groove 11, the output end of the motor 3 is fixedly connected to a rotating rod 31, the side of the rotating rod 31 close to the output end is fixedly connected to a driving wheel 32, a T-shaped slot 36 is provided on the outer wall of the top of the mounting seat 1, and the insides of the two T-shaped slots 36 are both slidably connected with T-shaped sliders 37, the outer wall of the top of the right T-shaped slider 37 is fixedly connected to a gear seat 1 33, and the outer wall of the top of the left T-shaped slider 37 is fixedly connected to a gear seat 2 34, the outer wall of the bottom of the gear seat 1 33 is slidably connected to the outer wall of the top of the mounting seat 1, the outer wall of the driving seat 2 is fixedly connected to a tooth 1 35, and the outer wall of the tooth 1 35 is meshed with the outer wall of one side of the tooth seat 1 33.

[0034] The tooth 1 35 is pushed to move by the tooth seat 1 33, and then the driving seat 2 can be rotated by the movement of the tooth 1 35, so that the tooth 1 35 on the other side of the driving seat 2 drives the tooth seat 2 34 to move, and at the same time drives the core pulling mechanism to move, and the driving seat 2 is fixed between the tooth seat 2 34 and the tooth seat 1 33, which effectively limits the deviation and shaking of the driving seat 2 during the rotation process, and further enhances the rotation stability of the driving seat 2.

[0035] Embodiment 3, on the basis of embodiment 2, the core pulling mechanism includes a mounting rod 1 41, the outer wall of the bottom of the mounting rod 1 41 is fixedly connected to the inner wall of the slot hole, the outer wall of the mounting rod 1 41 is rotatably connected to the connecting plate 4, six connecting plates 4 are provided with circular holes, the inside of the six circular holes are rotatably connected to the mounting rods 2 43, the outer walls of the bottoms of the six mounting rods 2 43 are fixedly connected to the arc-shaped forming plates 42, the outer walls of the six arc-shaped forming plates 42 are rotatably connected to the mounting rods 4 62, the outer walls of the mounting rods 4 62 are fixedly connected to the limiting wheel 63, the inside of the driving seat 2 is fixedly connected to the mounting ring, the outer wall of the top of the mounting ring is provided with a track groove 1 6, the inner walls of the six track grooves 6 are fixedly connected to the limiting teeth 61, the outer wall on one side of the limiting teeth 61 is meshed with the outer wall of the limiting wheel 63, and the inner wall of the mounting ring is fixedly connected to the inner teeth 51

[0036] The connecting plate 4 is driven to move by the mounting rod 1 41. Through the movement of the connecting plate 4, the mounting rod 2 43 can drive the arc-shaped forming plate 42 to rotate, thereby opening the core-pulling mechanism. Through precise mechanical linkage, the rapid and accurate opening of the core-pulling mechanism is realized, reducing the need for manual operation or complex mechanical structures, improving production efficiency. At the same time, the orderly connection and cooperation between multiple components make the entire mechanism structure compact, occupy a small area, help save space, and reduce manufacturing costs.

[0037] By limiting the movement trajectory of the arc-shaped forming plate 42, the deviation of the arc-shaped forming plate 42 during movement is avoided, correspondingly increasing the accuracy of the arc-shaped forming plate 42 during movement and reducing the deviation of the arc-shaped forming plate 42 during movement. At the same time, when the driving seat 2 stops moving, the limiting wheel 63 loses driving force. Then, through the meshing connection between the limiting wheel 63 and the limiting teeth 61, using the static friction force between the limiting wheel 63 and the limiting teeth 61, the mounting rod 4 62 drives the arc-shaped forming plate 42 to stop in place, avoiding the arc-shaped forming plate 42 from moving under the action of external forces in the static state, and correspondingly increasing the stability of the arc-shaped forming plate 42.

[0038] Embodiment 4. On the basis of Embodiment 3, a driving sleeve 54 is rotatably connected inside the circular groove 12. A track groove 2 59 is provided on the outer wall of the driving sleeve 54. An upward moving column 510 is slidably connected inside the driving sleeve 54. A guiding rod 511 is fixedly connected to the outer wall of the upward moving column 510. The outer wall of the guiding rod 511 is slidably connected to the inside of the track groove 2 59. A mounting plate 5 is fixedly connected to the outer wall at the top of the driving sleeve 54. A top-out needle 53 is fixedly connected to the outer wall at the top of the upward moving column 510. A top-out groove 52 is provided on the outer wall at the top of the mounting plate 5. The outer wall of the top-out needle 53 is slidably connected to the inside of the top-out groove 52. A plurality of mounting grooves 55 are provided on the outer wall of the mounting plate 5. A mounting rod 3 56 is fixedly connected to the inside of the mounting groove 55. A limiting block 57 is rotatably connected to the outer wall of the mounting rod 3 56. A pushing spring 58 is fixedly connected to the outer wall of one side of the limiting block 57. One end of the pushing spring 58 is fixedly connected to the inner wall of the mounting groove 55. The outer wall of the limiting block 57 is meshed with the outer wall of the internal tooth teeth 51.

[0039] By rotating the driving sleeve 54, the track groove 2 59 can push the guiding rod 511 upward, so that the guiding rod 511 drives the upward moving column 510 to move upward inside the driving sleeve 54. Through the movement of the upward moving column 510, the top-out needle 53 can be pushed to move upward, thereby jacking up the impeller, facilitating the demoulding of the injection-molded impeller, and improving production efficiency;

[0040] When the mounting ring drives the inner teeth 51 to rotate clockwise, the inner teeth 51 push the limit block 57, so that the limit block 57 rotates on the mounting rod 3 56 and enters the interior of the mounting groove 55, thereby avoiding the movement of the mounting plate 5 when it is not needed to work, and correspondingly increasing the flexibility of the mounting plate 5, so that the mounting plate 5 can adapt to different working requirements.

[0041] When the locking cam 72 is in the locked state, the locking cam 73 is in the locked state, and the locking cam 73 is in the locked state, so that the locking cam 73 is in the locked state.

[0042] By cooperating the slide bars and the slide grooves 71 on both sides of the half gear 7, the stability of the half gear 7 can be increased when the half gear 7 is fixed to the tooth seat 2 34, thereby avoiding rotation of the half gear 7 when the half gear 7 is fixed to the tooth seat 2 34, and correspondingly increasing the stability of the half gear 7, further improving the fixing effect of the half gear 7.

[0043] At this time, the motor 3 is started, and then through the operation of the motor 3, the rotating rod 31 can drive the driving wheel 32 to rotate accordingly, and then by utilizing the meshing connection between the driving wheel 32 and the tooth seat 1 33, when the driving wheel 32 rotates, the tooth seat 1 33 can drive the T-shaped slider 37 to move inside the T-shaped groove 36, so that the tooth seat 1 33 pushes the tooth 1 35 to move, and then through the movement of the tooth 1 35, the driving seat 2 can be rotated accordingly, so that the tooth 1 35 on the other side of the driving seat 2 drives the tooth seat 2 34 to move accordingly, and drives the core pulling mechanism to move, and the driving seat 2 is fixed between the tooth seat 2 34 and the tooth seat 1 33, which effectively limits the displacement and shaking of the driving seat 2 during the rotation process, and further enhances the rotation stability of the driving seat 2.

[0044] Subsequently, by driving the rotation of the driving seat 2, the mounting rod one 41 can drive the connecting plate 4 to move. Through the movement of the connecting plate 4, the mounting rod two 43 can drive the arc-shaped forming plate 42 to rotate, thereby opening the core-pulling mechanism. Through precise mechanical linkage, the rapid and accurate opening of the core-pulling mechanism is achieved, reducing the need for manual operation or complex mechanical structures, improving production efficiency. At the same time, the orderly connection and cooperation among multiple components make the entire mechanism structure compact, occupy a small area, help save space, and reduce manufacturing costs.

[0045] When the driving seat 2 rotates, the mounting ring can be driven to rotate accordingly. Subsequently, through the rotation of the mounting ring, the track groove one 6 and the limiting teeth 61 can be driven to rotate accordingly. Through the meshing connection between the limiting teeth 61 and the limiting wheel 63, the limiting wheel 63 can be driven to rotate when the limiting teeth 61 rotate. Due to the rotational connection between the mounting rod four 62 and the arc-shaped forming plate 42, the mounting rod four 62 can rotate with the limiting wheel 63. By sliding the mounting rod four 62 on the inner wall of the track groove one 6, the movement trajectory of the arc-shaped forming plate 42 can be limited, avoiding the deviation of the arc-shaped forming plate 42 during movement, correspondingly increasing the accuracy of the arc-shaped forming plate 42 during movement, and reducing the deviation of the arc-shaped forming plate 42 during movement. At the same time, when the driving seat 2 stops moving, the limiting wheel 63 will lose the driving force at this time. Then, through the meshing connection between the limiting wheel 63 and the limiting teeth 61, using the static friction force between the limiting wheel 63 and the limiting teeth 61, the mounting rod four 62 drives the arc-shaped forming plate 42 to stop in place, avoiding the movement of the arc-shaped forming plate 42 under the action of external forces in the static state, and correspondingly increasing the stability of the arc-shaped forming plate 42.

[0046] When the core-pulling mechanism finishes working and opens, when the driving seat 2 rotates counterclockwise, the mounting ring can be driven to rotate the internal teeth 51. Subsequently, through the rotation of the internal teeth 51, the internal teeth 51 can push the limiting block 57, thereby driving the limiting block 57 to move accordingly. Subsequently, through the movement of the limiting block 57, the mounting plate 5 drives the driving sleeve 54 to rotate accordingly. Subsequently, through the rotation of the driving sleeve 54, the track groove two 59 can push the guide rod 511 upward, thereby driving the upward movement of the upward moving column 510 inside the driving sleeve 54. Through the movement of the upward moving column 510, the ejector pin 53 can be pushed to move upward, thereby jacking up the impeller, facilitating the demolding of the injection-molded impeller, and improving production efficiency.

[0047] When the core-pulling mechanism starts to work, it drives the seat 2 to rotate clockwise. At this time, when the installation ring drives the internal tooth 51 to rotate clockwise, through the pushing of the internal tooth 51 on the limiting block 57, the limiting block 57 rotates on the third installation rod 56 and enters the inside of the installation groove 55, avoiding the movement of the installation plate 5 when it does not need to work, correspondingly increasing the flexibility of the installation plate 5 and enabling the installation plate 5 to adapt to different working requirements.

[0048] It should be noted that: after the demolding of the impeller is completed, the operator can manually rotate the installation plate 5 to restore the ejector pin 53 to its original position, and the limiting block 57 can be pushed out of the inside of the installation groove 55 through the arrangement of the pushing spring 58.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
