[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-5 This utility model provides a technical solution: a feeding device for injection molds, including a mounting frame 1, a support plate 2 connected to the bottom of the mounting frame 1, and further including:

[0044] Multiple support blocks 3, one side of the support block 3 is connected to one side of the support plate 2, and the same adjustment device 5 is connected to one side of the support block 3 on the same side;

[0045] Positioning device 4 is installed on the top of support plate 2. Positioning device 4 includes mounting groove 408, which is opened on the top of support plate 2. Motor 405 is installed in mounting groove 408. Multiple sliding plates 401 are driven by the output shaft of motor 405. Positioning plate 402 is connected to one side of sliding plate 401. Positioning plate 402 is driven to move linearly by sliding plate 401.

[0046] Furthermore, the positioning device 4 also includes:

[0047] Gear 409, the bottom of gear 409 is connected to the output shaft of motor 405;

[0048] Two racks 404, and the opposite sides of the two racks 404 mesh with the outer wall of the gear 409;

[0049] Two transmission plates 410 are provided, with the bottom of the transmission plate 410 connected to the top of the corresponding rack 404, and a transmission groove 411 is provided at the bottom of the transmission plate 410.

[0050] Furthermore, the positioning device 4 also includes:

[0051] Multiple transmission blocks 407, the bottom of the transmission block 407 is connected to the top of the corresponding sliding plate 401, and the outer wall of the transmission groove 411 is attached to and slidably connected to the inner wall of the transmission groove 411.

[0052] Multiple sliding sleeves 403 are provided, with the bottom of the sliding sleeve 403 connected to the top of the support plate 2, and the inner wall of the sliding sleeve 403 being attached to and slidably connected to the outer wall of the sliding plate 401.

[0053] Furthermore, a limiting groove 412 is provided at the top of the transmission groove 411, and two limiting plates 406 are slidably connected in the limiting groove 412. The bottom of the limiting plate 406 is connected to the top of the corresponding transmission block 407.

[0054] In a specific implementation, by setting a positioning device 4, when the upper and lower molds are closed, the output shaft of the motor 405 drives the gear 409 to rotate. The gear 409 meshes with the rack 404, causing the gear 409 to drive the two racks 404 to move towards each other. This causes the racks 404 to drive the corresponding transmission plate 410 to move. The transmission plate 410 drives the transmission groove 411 to move. The transmission block 407 slides in the transmission groove 411, causing the transmission groove 411 to drive the transmission block 407 to move. This causes the transmission block 407 to drive the sliding plate 401 to move, which in turn causes the sliding plate 401 to drive the positioning plate 402 to move. This allows the inner side of the positioning plate 402 to contact and fit against the outer side of the lower mold, thereby positioning the upper mold and preventing the upper and lower molds from shifting during mold closing, which would affect the final injection molding quality.

[0055] Adjustment device 5 includes:

[0056] Support block 501, one side of support block 501 is connected to one side of support block 3, and the bottom of support block 501 is provided with adjustment groove 503, and the top of adjustment groove 503 is provided with sliding groove 502;

[0057] The adjustment box 506 is attached to and slidably connected to the inner wall of the adjustment groove 503. The bottom of the adjustment plate is connected to the connecting frame 512, the bottom of the connecting frame 512 is connected to the hook 513, and the adjustment box 506 has through holes 507 on both sides.

[0058] The sliding block 505 is connected to the bottom of the adjusting box 506, and the outer wall of the sliding block 505 is attached to and slidably connected to the inner wall of the sliding groove 502.

[0059] Furthermore, the adjustment device 5 also includes:

[0060] Multiple pin holes 504 are provided on one side of the inner wall of the adjusting groove 503;

[0061] Two pins 509, the outer wall of pins 509 is slidably connected to the inner wall of through hole 507, and one end of pins 509 is inserted into the corresponding pin hole 504;

[0062] Two connecting plates 510 are connected on one side to one side of the pin 509, and two springs 515 are connected between the two connecting plates 510.

[0063] Furthermore, the adjustment device 5 also includes:

[0064] Two connecting blocks 516 are connected at the top to the bottom of the connecting plate 510, and a pressing block 511 is connected to one side of the connecting block 516. Pressing grooves 508 are provided on both sides of the adjusting box 506, and the inner wall of the pressing groove 508 is slidably connected to the outer wall of the pressing block 511.

[0065] Two support rods 514 are provided, and two sliding holes are provided in each of the two connecting plates 510. The inner walls of the two corresponding sliding holes are slidably connected to the outer walls of the support rods 514. The two ends of the support rods 514 are respectively connected to the two sides of the inner wall of the adjusting box 506, and the springs 515 are sleeved on the outside of the support rods 514.

[0066] In a specific implementation, by setting up an adjustment device 5, pressing the pressing block 511 causes the pressing block 511 to move the connecting block 516, which in turn moves the connecting plate 510. The movement of the connecting plate 510 causes the pin 509 to move out of the pin hole 504, thus disabling the pin hole 504 from fixing the pin 509. Furthermore, when the connecting plate 510 moves, it compresses the spring 515, causing the spring 515 to generate a rebound force. The support rod 514 supports the spring 515, preventing it from bending during compression. The spring 515 rebounds, and then the adjusting box 506 is moved, causing the adjusting box 506 to move the bottom hook 513. After moving to the desired position, the pressing block 511 is released, so that the connecting plate 510 is reset by the rebound of the spring 515. Then, the connecting plate 510 drives the pin 509 to be inserted into the new pin hole 504 for fixation. The hook 513 can be moved so that the hook 513 can be moved to a suitable lifting position according to the center of the mold, so as to avoid large deviations in the left and right center of gravity affecting the stability during lifting.

[0067] Working principle: In use, pressing the pressing block 511 according to the center position of the upper mold causes the pressing block 511 to move the connecting block 516, which in turn moves the connecting plate 510. This causes the connecting plate 510 to move the pin 509 out of the pin hole 504. The movement of the connecting plate 510 also compresses the spring 515, causing it to rebound. Then, the adjusting box 506 moves, causing the hook 513 to move, thus moving the lifting rod to the appropriate lifting position. Finally, releasing the pressing block 511 allows the connecting plate 510 to move again due to the rebound force of the spring 515. The resetting movement causes the connecting plate 510 to drive the pin 509 to insert into the pin hole 504, thereby re-fixing it. Subsequently, the motor 405 drives the gear 409 to rotate, the gear 409 drives the rack 404 to move, the rack 404 drives the transmission plate 410 to move, the transmission plate 410 drives the transmission block 407 to move through the transmission groove 411, the transmission block 407 drives the sliding plate 401 to move, so that the sliding plate 401 drives the positioning plate 402 to move, so that the positioning plate 402 moves to the outside of the lower mold and fits, thereby positioning the upper mold and avoiding displacement during mold closing that would affect the injection molding quality.
