[0001] The utility model relates to the technical field of injection molding devices, in particular to a precision injection molding device for handicraft plastic parts. Background Art

[0002] Injection molding is a method of producing industrial products. In the production process of rubber handicrafts, injection molds are needed to injection mold the handicrafts. Generally, the injection mold consists of an upper module and a lower module. During injection molding, the two modules are merged together. After the injection molding is completed, the two modules are separated, and then the handicraft is taken out.

[0003] However, traditional injection molds produce some harmful gases during the injection process. These gases will drift into the air when the upper and lower modules are opened, which can easily cause air pollution. At the same time, if inhaled by workers, they will cause damage to their bodies, resulting in poor environmental protection and safety.

[0004] Therefore, it is necessary to design an injection molding device with higher safety. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a precision injection molding device for handicraft plastic parts, which facilitates the purification of harmful gases generated during the injection molding process when the upper module and the lower module are opened, thereby improving the environmental protection and safety of use.

DETAILED DESCRIPTION

[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments. Example 1

[0024] In order to improve the safety of the injection molding device, a precision injection molding device for handicraft plastic parts is designed. The specific solution is as follows:

[0025] like Figure 1-4 As shown, a precision injection molding device for plastic parts of handicrafts includes a base 1, a lower module 2 is installed on the base 1, four guide rods 6 are fixedly connected to the base 1, the four guide rods 6 are slidably connected to the same movable plate 4, an upper module 5 is installed at the bottom end of the movable plate 4, a purification structure 7 is provided on the base 1, the purification structure 7 includes a connecting box 701 and a fan 702, a connecting box 701 is fixedly connected to the base 1, a fan 702 is installed on one side of the connecting box 701, an air inlet 703 is provided on the other side of the connecting box 701, a connecting frame 704 is slidably connected to the connecting box 701, two trawl nets 705 are fixedly connected to the connecting frame 704, a plurality of activated carbon honeycomb blocks 706 are placed on the trawl net 705, and a fixed structure 9 is provided on the connecting box 701.

[0026] like Figure 1 As shown, two hydraulic cylinders 3 are installed on the base 1, and the top ends of the two hydraulic cylinders 3 are fixedly connected to the bottom end of the same movable plate 4, so that the movable plate 4 can be moved, thereby opening the upper module 5.

[0027] like Figure 3As shown, a sealing gasket 8 is engaged with the top of the connection box 701 , and the sealing gasket 8 contacts the connection frame 704 , thereby improving the sealing performance between the connection box 701 and the connection frame 704 .

[0028] like Figure 1 and Figure 3 As shown, the edge of the top of the connection frame 704 extends to the outside of the connection box 701, and the upper module 5 is located directly above the lower module 2, so the connection frame 704 can be easily moved.

[0029] like Figure 1 and Figure 2 As shown, the fixed structure 9 includes a rotating rod 901 and a connecting rod 902. Two rotating rods 901 are rotatably connected to both sides of the connecting box 701. The connecting rod 902 is rotatably connected to the rotating rod 901. A connecting plate 903 is fixedly connected between the two connecting rods 902. Two screws 905 are threadedly connected to the connecting plate 903. The bottom end of the screw 905 is rotatably connected to a stop block 906. The stop block 906 and the connecting frame 704 are in contact with each other. A T-shaped structure is formed between the screw 905 and the stop block 906, and an L-shaped structure is formed between the connecting plate 903 and the connecting rod 902. Therefore, the connecting frame 704 can be quickly disassembled, thereby facilitating the replacement of the activated carbon honeycomb block 706.

[0030] like Figure 1 As shown, a handle 904 is fixedly connected to the top of the screw rod 905 . The handle 904 passes through the screw rod 905 and is perpendicular to the screw rod 905 . Therefore, the screw rod 905 can be easily rotated by the handle 904 .

[0031] Working principle:

[0032] When the injection molding is completed, the two hydraulic cylinders 3 can be started at the same time. The two hydraulic cylinders 3 extend to drive the movable plate 4 to move. The four guide rods 6 can play a role in guiding the movement of the movable plate 4. The movement of the movable plate 4 will drive the upper module 5 to move away from the lower module 2, so that the upper module 5 is opened. In the process of opening the upper module 5, the fan 702 can be started. Under the action of the fan 702, the harmful gas generated during the injection molding process will enter the interior of the connecting box 701 from the air inlet 703. In the process of the harmful gas flowing inside the connecting box 701, the harmful substances in the harmful gas can be adsorbed and removed by multiple activated carbon honeycomb blocks 706. The purified air can be discharged from one end of the fan 702, thereby achieving the purification of the harmful gas, avoiding the harmful gas generated during the injection molding process from drifting into the surrounding environment when the upper module 5 is opened, thereby improving the safety and environmental protection of use, and when the activated carbon honeycomb block 706 needs to be replaced, it can be replaced. The two handles 904 can be rotated in sequence. The rotation of the handles 904 will drive the screw 905 to rotate, and the rotation of the screw 905 will drive the block 906 to move away from the connecting frame 704. When the two blocks 906 do not interfere with the connecting frame 704, the connecting rod 902 can be rotated 180 degrees, and then the rotating rod 901 is rotated to make the connecting plate 903 deviate from the top of the connecting frame 704. Then, the connecting frame 704 can be taken out from the inside of the connecting box 701, and then the old activated carbon honeycomb block 706 can be removed from the trawl 705, and the new activated carbon honeycomb block 706 can be placed on the trawl 705. Then, the connecting frame 704 is placed into the inside of the connecting box 701, and the connecting frame 704 is fixed by the two blocks 906, thereby realizing the replacement of the activated carbon honeycomb block 706. By regularly replacing the activated carbon honeycomb block 706, the occurrence of incomplete purification of harmful gases can be avoided, thereby ensuring the effect of harmful gas purification.
