[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Depend on Figures 1-6 The present invention includes an installation plate 1, on the upper surface of which an installation base 11 is fixedly connected. A slot 12 is provided on the surface of the installation base 11. The mold core 4 is placed inside the slot 12. An installation block 2 is fixedly connected to the inner wall of the slot 12. An installation component for installing and removing the mold core 4 is installed inside the installation block 2. The mold core 4 is installed by the installation component. A fixing frame 13 is fixedly connected to and communicates with the outer wall of the installation base 11. A locking component for limiting the installation component is movably provided on the upper surface of the fixing frame 13. After the installation component is limited by the locking component, the mold core 4 can be fixedly installed. The mold core 4 is movably installed on the inner wall of the slot 12.

[0025] The locking assembly also includes a turntable 3 rotatably connected to the upper surface of the fixed frame 13. A handle 31 is fixedly connected to the eccentric position of the upper surface of the turntable 3. The lower surface of the turntable 3 is fixedly connected to the first toothed pulley 33 through a fixed shaft. The handle 31 drives the turntable 3 to rotate, which in turn drives the first toothed pulley 33 to rotate in conjunction with the fixed shaft.

[0026] The locking assembly includes a first toothed pulley 33 rotatably connected inside the fixed frame 13, a second toothed pulley 35 fixedly connected to the upper surface of the drive gear 27, and a toothed belt 34 sleeved on the outer wall of the first toothed pulley 33 and the second toothed pulley 35. The first toothed pulley 33, in conjunction with the toothed belt 34, drives the second toothed pulley 35 to rotate. The mounting assembly also includes a driven gear 26 rotatably connected inside the mounting base 11. The upper surface of the driven gear 26 is connected to the rotating block 22 through a fixed shaft. The drive gear 27 (the size of the drive gear 27 is smaller than the size of the driven gear 26) rotatably connected inside the mounting base 11 is meshed on one side of the driven gear 26. The drive gear 27 can be driven to rotate through the second toothed pulley 35.

[0027] The driven gear 26 can be driven to rotate by the driving gear 27. With the cooperation of the fixed shaft, the driven gear 26 drives the rotating block 22 to rotate.

[0028] The mounting block 2 has a cavity 21 inside. The mounting assembly includes a rotating block 22 rotatably connected to the cavity 21 via a torsion spring (the torsion spring can drive the rotating block 22 to reset, and when the rotating block 22 resets, the pushing force of the push block 23 on the guide block 241 is canceled). Four sets of push blocks 23 are symmetrically fixedly connected to the outer wall of the rotating block 22. Four sets of insert rods 24 are symmetrically and movably sleeved on the inner wall of the cavity 21. One end of the insert rod 24 is fixedly connected to the guide block 241, and the outer wall of the insert rod 24 is sleeved with a rod that is fixedly connected to the guide block 241. The first spring 25 (which can drive the insertion rod 24 to reset) has its other end fixedly connected to the cavity 21. When the rotating block 22 rotates, the push block 23 abuts against the guide block 241, pushing the insertion rod 24 to move. The lower surface of the mold core 4 is provided with an installation groove 41. The inner wall of the installation groove 41 is symmetrically provided with four sets of slots 42. When the mold core 4 is inserted into the inner wall of the slot 12, the insertion rod 24 is just aligned with the slot 42. After the insertion rod 24 is inserted into the inner wall of the slot 42, the mold core 4 can be fixedly installed.

[0029] A connecting block 32 is fixedly connected to the outer wall of the turntable 3. A limiting block 14 that engages with the connecting block 32 is rotatably connected to the upper surface of the side wall of the fixed frame 13. After the mold core 4 is fixed, the positioning rod 36 is pulled and the limiting block 14 is rotated. After the positioning rod 36 fixes the limiting block 14, the handle 31 is released, and the turntable 3 can be limited by the limiting block 14 in conjunction with the connecting block 32.

[0030] A positioning rod 36 is movably sleeved on the surface of the limiting block 14. A second spring 37 is fixedly sleeved on the lower part of the outer wall of the positioning rod 36 (the second spring 37 can reset the positioning rod 36). The top of the second spring 37 is fixedly connected to the fixing groove 16. A through hole 15 is opened on the upper surface of the limiting block 14. The positioning rod 36 is sleeved on the inner wall of the through hole 15. A fixing groove 16 communicating with the through hole 15 is opened on the lower surface of the limiting block 14. A positioning groove matching the positioning rod 36 is opened on the upper surface of the fixing frame 13. By inserting the positioning rod 36 into the inner wall of the positioning groove, the limiting block 14 is limited, and the mold core 4 can be fixedly installed.

[0031] Working principle: When the mold core 4 needs to be installed, the mold core 4 is clamped into the inner wall of the slot 12 on the mounting base 11. The handle 31 drives the turntable 3 to rotate clockwise. The turntable 3 drives the first toothed pulley 33 to rotate. The first toothed pulley 33 drives the second toothed pulley 35 to rotate through the toothed belt 34. The second toothed pulley 35 drives the driving gear 27 to rotate. The driving gear 27 drives the driven gear 26 to rotate. Under the action of the driven gear 26, the rotating block 22 rotates. The rotating block 22 drives the insertion rod 24 to move through the push block 23 and the guide block 241. When the turntable 3 can no longer rotate, the insertion rod 24 just passes through the inner wall of the slot 42, limiting the mold core 4. Then, the positioning rod 36 is pulled to move the limiting rod 24. Rotating the positioning block 14 clockwise by 90 degrees releases the positioning rod 36. The positioning rod 36 resets under the action of the second spring 37 and inserts into the inner wall of the positioning groove to limit the positioning block 14. Then, the handle 31 is released, and the rotating block 22 resets under the action of the torsion spring, driving the turntable 3 to rotate. The connecting block 32 engages with the limiting block 14 to limit the turntable 3, thus completing the fixed installation of the mold core 4. When it is necessary to disassemble the mold core 4, simply release the limiting block 14 from the connecting block 32. The rotating block 22 resets under the action of the torsion spring, and at the same time, under the action of the first spring 25, the insert rod 24 separates from the slot 42, thus releasing the limiting rod 24 from the mold core 4, facilitating quick disassembly of the mold core 4.
