[0027] The upper mold 2 is connected to an external device, and the injection plastic is injected into the internal cavity of the mold through the injection port 11. After the injection is completed, the injection mold is cooled by the cooling mechanism, so that the internal product of the injection mold is formed. The electric telescopic rod 3 extends to move the lower mold 1 downward, and the lower mold 1 moves downward to drive the fixed mold 4 and the movable mold 8 to move downward synchronously. The movable mold 8 moves downward to gradually separate from the lower left side of the upper mold 2. The elastic force of the connecting spring 15 causes the movable mold 8 to move to the left. During the movement of the movable mold 8 to the left, it drives the connecting rod 7, the side core pulling mechanism 5 and the electromagnet 6 to move to the left synchronously, and the side core pulling mechanism 5 moves to the left. The left side moves gradually and separates from the finalized product, the fixed mold 4 drives the limit rod 10 to move downward synchronously, when the limit rod 10 moves downward to the lowest position, the upper mold 2 limits the limit rod 10, the electric telescopic rod 3 continues to extend, and the electric telescopic rod 3 drives the rubber ball 13 to move downward synchronously, and during the downward movement of the rubber ball 13, the limit hole 14 squeezes the rubber ball 13, so that the rubber ball 13 is deformed and separated from the limit hole 14, the lower mold 1 moves downward, driving the internally formed product to move downward synchronously, the lower mold 1 is separated from the fixed mold 4, and then the internally formed product of the lower mold 1 can be taken out.

[0028] The adjusting mechanism is arranged inside the fixed mold 4, and the arrangement of the adjusting mechanism facilitates the disassembly of the side core-pulling mechanism 5; the adjusting mechanism includes a through electromagnet 6, a threaded rod 16 and a fixed rod 17, the right side of the movable mold 8 is rotatably connected with the threaded rod 16, the outer side of the threaded rod 16 is threadedly connected with the connecting rod 7, the connecting rod 7 is arranged in a "Z" shape, the right end of the connecting rod 7 is installed with the through electromagnet 6, the right side of the through electromagnet 6 adsorbs the side core-pulling mechanism 5, the end of the side core-pulling mechanism 5 in contact with the through electromagnet 6 is made of iron, the fixed rod 17 runs through the inside of the connecting rod 7, and the fixed rod 17 is installed on the right side of the movable mold 8.

[0029] After the cam 16 is turned on, the movable mold 8 is pushed to the right by hand, so that the cam 16 moves to the top of the cavity. Then, the threaded rod 16 is turned on by hand, and the threaded rod 16 rotates to make the connecting rod 7 move downward, and the connecting rod 7 is limited by the fixed rod 17, so that the connecting rod 7 can only move up and down. During the up and down movement of the connecting rod 7, the cam 16 drives the cam 6 to move up and down synchronously until the cam 6 moves downward and is completely located outside the fixed mold 4, and the threaded rod 16 is no longer rotated. Then, the cam 6 is powered on, and the cam 6 generates suction after the power is connected to the power supply, and the side core pulling mechanism 5 is placed in a suitable position. Then, the threaded rod 16 is rotated in the opposite direction, and the side core pulling mechanism 5 and the cam 6 move upward until they can no longer move. Release the hand pushing the movable mold 8, and the elastic force of the connecting spring 15 makes the movable mold 8 move to the left, so that the cam 6 returns to its original position.

The diameter of the rubber ball 13 is larger than the opening diameter of the limiting hole 14, and the internal diameter of the limiting hole 14 is larger than the diameter of the rubber ball 13.

[0031] The electric telescopic rod 3 moves the lower mold 1 upward. When the lower mold 1 moves upward to contact with the fixed mold 4, it pushes the fixed mold 4 to move upward. The upward movement of the fixed mold 4 drives the movable mold 8 to move upward synchronously. After the movable mold 8 moves upward to the lower left corner of the upper mold 2, the upper mold 2 pushes the movable mold 8 to move to the right. The movable mold 8 drives the side core pulling mechanism 5, the electromagnet 6 and the connecting rod 7 to move to the right synchronously. The movable mold 8 moves to the right synchronously during the upward movement. During the movement of the movable mold 8, the inclined guide column 9 is inserted into the through hole 12. When the fixed mold 4 moves upward to be completely fitted with the upper mold 2, the upper mold 2 limits the fixed mold 4, and the lower mold 1 continues to move upward. The upward movement of the lower mold 1 drives the rubber ball 13 to move upward synchronously. During the upward movement of the rubber ball 13, the limiting hole 14 squeezes the rubber ball 13. After the rubber ball 13 is squeezed and deformed, it is engaged in the limiting hole 14 until the electric telescopic rod 3 can no longer be shortened.
