[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-6 As shown, a common mold for toy production includes a common mold cup 1, which is installed on an injection molding machine. A sub-mold 2 is provided in the common mold cup 1, and locking screws 5 are installed on both sides of the common mold cup 1. The sub-mold 2 is fixed in the common mold cup 1 by the locking screws 5. After loosening the locking screws 5, the sub-mold 2 can be taken out of the common mold cup 1 for replacement without removing the common mold cup 1 from the injection molding machine. This simplifies the replacement procedure and improves the replacement efficiency, so that the replacement process of the sub-mold 2 only takes ten to twenty minutes. A first injection port 3 is provided on the side of the common mold cup 1 close to the extrusion port of the injection molding machine, and a second injection port 4 is provided on the side of the sub-mold 2 close to the first injection port 3. The first injection port 3 is connected to the second injection port 4. A first locking structure 8 is installed on the top of the sub-mold 2, and a second locking structure 9 is installed on the top of the common mold cup 1.

[0025] The common mold cup 1 includes a fixed mold cup 101 and a movable mold cup 102. The fixed mold cup 101 is fixedly connected to the extrusion port of the injection molding machine, and the movable mold cup 102 is fixedly connected to the hydraulic power end of the injection molding machine. The sub-mold 2 includes a fixed mold 201 and a movable mold 202. The fixed mold cup 101 and the movable mold cup 102 are closed to form an accommodating cavity. The fixed mold 201 and the movable mold 202 are arranged in the accommodating cavity. The fixed mold 201 is fixedly connected to the fixed mold cup 101 by a locking screw 5, and the movable mold 202 is fixedly connected to the movable mold cup 102 by a locking screw 5. The first injection port 3 is opened on the fixed mold cup 101, and the second injection port 4 is opened on the fixed mold 201. The first injection port 3 is connected to the extrusion port of the injection molding machine. The injection molding machine extrude the molten plastic into the first injection port 3, and then the molten plastic enters the mold cavity between the fixed mold 201 and the movable mold 202 through the second injection port 4.

[0026] Vertically arranged guide grooves 6 are provided on both sides of the movable mold 202, and guide blocks 7 are fixedly connected to the inner walls of the fixed mold cup 101 and the movable mold cup 102. The guide grooves 6 cooperate with the guide blocks 7. Through the guiding effect of the guide grooves 6 and the guide blocks 7, the sub-mold 2 is easily installed in the common mold cup 1, ensuring that the positions of the sub-mold 2 and the common mold cup 1 are accurately installed.

[0027] The first locking structure 8 includes a first locking module 801, which is arranged on the top of the sub-mold 2. The first locking module 801 is equipped with a first locking screw 802 and a second locking screw 803. The first locking screw 802 is threadedly connected to the top of the fixed mold 201, and the second locking screw 803 is threadedly connected to the top of the movable mold 202. The first locking module 801 is fixed to the sub-mold 2 by the first locking screw 802 and the second locking screw 803. The top of the first locking module 801 is fixedly connected with a first lifting ring 804. The fixed mold 201 and the movable mold 202 are fixed together through the first locking module 801, and then the first lifting ring 804 is connected to the external lifting equipment to lift the sub-mold 2, which is convenient for replacing and installing the sub-mold 2.

[0028] A semicircular groove 805 is provided at one end of the first locking module 801, and the semicircular groove 805 forms an opening with the side wall of the first locking module 801, and the opening direction faces the second locking screw 803 in the front. The first locking screw 802 passes through the first locking module 801 in the up and down direction. When the first locking screw 802 and the second locking screw 803 are in the loose state, the first locking module 801 can rotate around the first locking screw 802, turn the semicircular groove 805 to the second locking screw 803, and then tighten the first locking screw 802 and the second locking screw By tightening 803, the fixed mold 201 and the movable mold 202 can be fixed together. When the fixed mold 201 and the movable mold 202 need to be separated, the first locking screw 802 and the second locking screw 803 are loosened, and the first locking module 801 can be rotated to make the first locking module 801 away from the second locking screw 803. At this time, the fixed mold 201 and the movable mold 202 are in a separated state, so there is no need to remove the first locking module 801, the first locking screw 802 and the second locking screw 803, which facilitates operation.

[0029] The second locking structure 9 includes a second locking module 901, which is arranged on the top of the common mold cup 1. Two mounting screws 902 are installed on the second locking module 901. The second locking module 901 is fixedly connected to the fixed mold cup 101 and the movable mold cup 102 through the mounting screws 902. A second lifting ring 903 is fixedly connected to the top of the second locking module 901. When the common mold cup 1 is in use, the second locking module 901 and the mounting screws 902 are removed from the common mold cup 1. If the common mold cup 1 needs to be hoisted, the second locking module 901 is installed on the common mold cup 1 using the mounting screws 902, so that the fixed mold cup 101 and the movable mold cup 102 are connected together, and then the second lifting ring 903 is connected to the external hoisting equipment to hoist the common mold cup 1.

[0030] Working principle: First, use external lifting equipment to connect the second lifting ring 903 to lift the common mold cup 1, fix the fixed mold cup 101 to one end of the extrusion port of the injection molding machine, connect the movable mold cup 102 to the hydraulic power end of the injection molding machine, unscrew the mounting screw 902 to remove the second locking module 901, and then use external lifting equipment to connect the first lifting ring 804 to lift the sub-mold 2, so that the sub-mold 2 enters the common mold cup 1 from top to bottom, and use the locking screw 5 to fix the sub-mold 2 in the common mold cup 1, loosen the second locking screw 803 and the first locking screw 802, and move the first locking module 801. The first locking module 801 rotates with the first locking screw 802 as the axis, so that the first locking module 801 is away from the second locking screw 803, thereby releasing the fixed mold. 201 and the movable mold 202 are fixedly connected. At this time, the fixed mold cup 101 and the fixed mold 201 are fixed as one, and the movable mold cup 102 and the movable mold 202 are fixed as one. The hydraulic power end of the injection molding machine is used to drive the movable mold cup 102 to move, so that the movable mold 202 is separated or fitted with the fixed mold 201, completing the injection molding and toy removal operations. When replacing the sub-mold 2, first close the fixed mold 201 and the movable mold 202, and then rotate the first locking module 801 to make the second locking screw 803 enter the semicircular groove 805, tighten the first locking screw 802 and the second locking screw 803, and now the fixed mold 201 and the movable mold 202 are connected as one again, loosen the locking screw 5, and then use external lifting equipment to lift the sub-mold 2 to complete the disassembly of the sub-mold 2.
