[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides an injection mold for a gas filter housing, including a fixed mold base plate 1, a fixed template 11, a movable mold base plate 12, and a movable template 13. The fixed mold base plate 1 is fixedly connected to the fixed template 11, and the movable template 13 is fixedly connected to the movable mold base plate 12. A mold cavity is provided between the fixed template 11 and the movable template 13 for molding the gas filter housing. Support seats 17 are installed at the four corners of the bottom surface of the fixed mold base plate 1, and guide rods 14 are installed at the four corners of the upper surface of the fixed mold base plate 1. The movable mold base plate 12 slides on the surface of the guide rods 14 through through holes opened at the four corners. Two guide rods are symmetrically installed on the surface of the fixed mold base plate 1. A hydraulic cylinder 15 has a telescopic rod 16 installed at its extended end. The end of the telescopic rod 16 away from the fixed mold base plate 1 is connected to the bottom of the moving mold base plate 12. A storage tank 23 is installed on the upper surface of the moving mold base plate 12. The storage tank 23 is connected to the moving mold plate 13 through a connecting pipe. A mold cavity is provided between the fixed mold plate 11 and the moving mold plate 13. This mold cavity is used to form the gas filter housing. Driven by the hydraulic cylinder 15, the moving mold base plate 12 and the fixed mold base plate 1 can be opened and closed, which facilitates the injection and demolding operations of the mold. The storage tank 23 is connected to the moving mold plate 13 through a connecting pipe and is used to store and transport injection molding raw materials.

[0023] Cooling channels 18 are provided in both the fixed template 11 and the moving template 13. The inlet and outlet of the cooling channels 18 extend to the outside of the fixed template 11 and the moving template 13, respectively. The cooling channels 18 are connected to external cooling equipment, which enables the coolant to circulate in the cooling channels 18. Through the external cooling equipment, the coolant can circulate in the cooling channels 18, quickly remove the heat in the mold cavity, thereby improving the cooling efficiency.

[0024] The fixed mold plate 11 is equipped with a demolding mechanism, which includes a top plate 20 located on the bottom surface of the fixed mold plate 11. A telescopic cylinder 21 is installed at the center of the bottom surface of the fixed mold base plate 1. A fixing rod 22 is installed at the extended end of the telescopic cylinder 21. The end of the fixing rod 22 away from the telescopic cylinder 21 is connected to the bottom of the top plate 20. The inside of the fixed mold plate 11 is coated with an anti-stick coating. After injection molding is completed, the telescopic cylinder 21 drives the fixing rod 22 to move the top plate 20 upward, thereby smoothly ejecting the formed gas filter shell and achieving rapid demolding.

[0025] It should be noted that the cooling channel 18 is arranged in a spiral shape around the inner wall of the mold. This design greatly increases the contact area and contact time between the coolant and the mold, improves the cooling efficiency, and shortens the injection molding cycle.

[0026] It should be noted that the top plate 20 is adapted to the inner wall surface of the fixed template 11, and a sealing gasket is provided on the side surface of the top plate 20 that is in contact with the inner bottom surface of the fixed template 11, which ensures the sealing and stability of the top plate 20 during the movement process and avoids raw material leakage.

[0027] The moving template 13 has a runner 19 inside, which is connected to the mold cavity. The molten plastic from the injection molding machine enters the mold cavity through the connecting pipe and the runner 19 to complete the injection molding process. This allows the injection molding material to be evenly distributed in the mold cavity, ensuring the molding quality of the gas filter shell.

[0028] like Figures 1 to 4 As shown, the system also includes a stirring mechanism housed within the storage tank 23. This stirring mechanism comprises stirring blades 25 arranged within the storage tank 23. Each stirring blade 25 consists of multiple sets of blades facing different directions and is arranged at an angle. A stirring motor 24 is mounted on the top of the storage tank 23. The output end of the stirring motor 24 is connected to one end of the stirring blades 25. A conveying auger 26 is installed at the other end of the stirring blades 25. The conveying auger 26 is located inside the connecting pipe. Driven by the stirring motor 24, the stirring blades 25 rotate, effectively stirring the raw materials within the storage tank 23 and ensuring a more uniform mixture. Simultaneously with the rotation of the stirring blades 25, the conveying auger 26 stably transports the uniformly mixed raw materials to the moving mold plate 13, ensuring the continuity and stability of the injection molding process.

[0029] In addition, the inner wall of the storage tank 23 is equipped with a spiral heating tube, which can heat the raw materials in the storage tank 23 to maintain a suitable temperature and fluidity; the outer wall of the storage tank 23 is also equipped with an insulation layer, which can reduce heat loss and save energy.

[0030] Working principle and process: When using the injection mold for the gas filter housing, first slide the moving mold base plate 12 along the guide rod 14 until it closes with the fixed mold base plate 1. Drive the telescopic rod 16 through the hydraulic cylinder 15 to make the moving mold base plate 12 and the fixed mold base plate 1 fit tightly together to form a closed mold cavity. Put the raw material into the storage tank 23, start the stirring motor 24, and the stirring blades 25 stir and mix the raw material. At the same time, the conveyor auger 26 transports the uniformly mixed raw material through the connecting pipe to the moving mold plate 13, and then injects it evenly into the mold cavity through the distribution channel 19.

[0031] The external cooling equipment is activated, causing the coolant to circulate within the cooling channels 18 of the fixed mold plate 11 and the moving mold plate 13, cooling the mold and accelerating the solidification of the injection molding material. After the injection molding material has solidified, the telescopic cylinder 21 drives the fixed rod 22 to move the top plate 20 upward, ejecting the formed gas filter housing from the fixed mold plate 11 and completing the demolding operation.

[0032] Throughout the injection molding process, the heating tubes on the inner wall of the storage tank 23 heat the raw material, while the insulation layer on the outer wall keeps the raw material temperature stable, ensuring good fluidity and guaranteeing the smooth progress of the injection molding process.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
