[0036] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] like Figure 1-Figure 10As shown, an air guide hood injection mold includes a first mold 101, a second mold 102, a multi-component blade and a plurality of cylinders; the first mold 101 has a first mold cavity for molding a hard material; the second mold 102 has a second mold cavity for molding a soft material; the first mold 101 and the second mold 102 are connected together, the first mold cavity and the second mold cavity are connected, and the first mold cavity and the second mold cavity are respectively connected to two injection tubes so as to separately inject products of different materials into the first mold cavity and the second mold cavity; a split blade is arranged at the connection between the first mold 101 and the second mold 102; the cylinder is used to drive the split blade to move; the cylinder drives the split blade to move so that the air guide hood injection mold has at least a hard plastic injection molding process in which the first mold cavity and the second mold cavity are separated and a soft plastic injection molding process in which the first mold cavity and the second mold cavity are connected.

[0038] Further, such as Figure 3 As shown, the dividing blades include a first dividing blade 107, a second dividing blade 110, a third dividing blade 121 and a fourth dividing blade 122, the first dividing blade 107 is arranged at the top of the first mold cavity, the second dividing blade 110 is arranged at the bottom of the first mold cavity, the third dividing blade 121 is arranged at one side of the first mold cavity, and the fourth dividing blade 122 is arranged at the other side of the first mold cavity; that is, the first dividing blade 107, the second dividing blade 110, the third dividing blade 121 and the fourth dividing blade 122 are respectively arranged on the four sides of the first mold cavity; when the first dividing blade 107, the second dividing blade 110, the third dividing blade 121 and the fourth dividing blade 122 move into the first mold cavity, the first dividing blade 107, the second dividing blade 110, the third dividing blade 121 and the fourth dividing blade 122 cooperate to form a partition structure; through the movement of the dividing blades, the dividing blades can ensure that the hard material and the soft material will not penetrate each other during the injection molding process, thereby maintaining their independent molding.

[0039] like Figure 1 , 3 As shown, the cylinder includes a first cylinder 116, a second cylinder, a third cylinder and a fourth cylinder. The first cylinder 116 drives the first dividing blade 107 to move, the second cylinder drives the second dividing blade 110 to move, the third cylinder drives the third dividing blade 121 to move, and the fourth cylinder drives the fourth dividing blade 122 to move.

[0040] Furthermore, the air guide cover injection mold further includes a first movable plate 105 and a first push block 115. The first movable plate 105 is slidably connected to the first mold 101; the first push block 115 is arranged on the piston rod of the first cylinder 116; the first dividing blade 107 is connected to the first movable plate 105, and the first movable plate 105 is provided with a first groove, and the first push block 115 is inserted into the first groove. The first movable plate 105 slides along the first movable groove under the action of the first cylinder 116, ensuring that the first dividing blade 107 is closely matched with the mold cavity, thereby achieving precise injection molding.

[0041] like Figure 5 As shown, a first guide block 1152 is provided on the side wall of the first push block 115, and a first guide groove corresponding to the first guide block 1152 is provided on the inner wall of the first groove, and the first guide block 1152 and the first guide groove are arranged obliquely. Through the cooperation between the first guide block 1152 and the first guide groove, when the first push block 115 slides in the first groove, the moving direction of the split blade can be effectively guided to ensure its smooth movement, so that when the first push block 115 moves in the horizontal direction, the first split blade 107 can move in the vertical direction, and the stroke of the first cylinder 116 is controlled to reduce the overall volume of the mold.

[0042] Furthermore, the first mold 101 is provided with a first movable groove and a second movable groove, the second movable groove is provided on the side wall of the first movable groove, and the second movable groove and the first movable groove are arranged vertically; the first movable plate 105 is in the first movable groove, and the first push block 115 is in the second movable groove; a slider 1151 is provided on the side wall of the first push block 115, and a guide cover 119 is connected to the second movable groove, and the guide cover 119 is a right-angle structure, and the guide cover 119 is connected to the second movable groove by screws to form a slide groove for the slider 1151 to move. The cooperation between the slider 1151 and the guide cover 119 makes the movement of the first push block 115 in the horizontal direction more stable, thereby improving the accuracy of the movement of the first dividing blade 107 in the vertical direction. In this way, even in a complex injection molding process, the molding effect of hard and soft materials can be guaranteed, and contamination and molding defects between materials can be avoided. This design not only improves the quality of the product, but also extends the service life of the mold and reduces the maintenance cost.

[0043] like Figure 4-5 As shown, a second guide block is provided on the inner wall of the first movable groove, a second guide groove 1051 corresponding to the second guide block is provided on the first movable plate 105, a first convex block 113 is provided on the top of the second guide groove 1051, a return spring 114 is provided on the first convex block 113, and the return spring 114 is located between the second guide block and the first convex block 113. When the soft glue needs to be injected, the first cylinder 116 drives the first push block 115 to move back, and the return spring 114 pushes the first convex block 113 to cooperate with the movement of the first guide block 1152 and the first guide groove, so that the first movable plate 105 and the first dividing blade 107 quickly return to the initial position, ensuring the continuity and efficiency of the entire injection molding process. Through the optimized mold design, not only the production cycle is shortened, but also the consistency and reliability of the product are improved.

[0044] The first movable plate 105 is provided with a guide hole, in which a guide rod 108 is passed, a mounting groove corresponding to the guide rod 108 is provided on the side wall of the first movable groove, a fixing block 112 is provided in the mounting groove, and a positioning groove corresponding to the guide rod 108 is provided on the fixing block 112. The cooperation between the guide rod 108, the guide hole and the positioning groove ensures the stability of the movable plate during operation, while reducing the risk of wear and damage.

[0045] Further, such as Figure 2-3 As shown, convex strips are provided at both ends of the first movable plate 105, and a receiving groove corresponding to the first movable plate 105 is provided on the second mold 102. A first notch is provided on the side wall of the first movable groove, and a second notch is provided on the side wall of the receiving groove. The first notch and the second notch cooperate to form a guide cavity, and a guide rod 106 is provided in the guide cavity, and the convex strips are against the guide rod 106. The cooperation between the convex strips and the guide rod 106 makes the first movable plate 105 move more smoothly in the vertical direction, ensuring the stability and accuracy of the mold during the cutting process, thereby effectively improving the cutting efficiency and the consistency of the product. The precise design of the guide rod 106 further reduces the noise and vibration during operation, and ensures the reliability of the mold for long-term operation.

[0046] Furthermore, a connecting rod is connected to the piston rod of the first cylinder 116, and a connecting block is provided at one end of the connecting rod. A connecting groove corresponding to the connecting block is provided on the first push block 115, and a second protrusion 117 is provided on the inner wall of the connecting groove. A plug rod 118 is provided on the second push block, and a socket corresponding to the plug rod 118 is provided on the connecting block. The connecting rod is closely connected to the first push block 115 through the connecting block, ensuring that the movement of the piston rod can be accurately transmitted to the push block, so that the piston rod of the first cylinder 116 can drive the first push block 115 to move when telescopically moving, thereby realizing the feeding and resetting of the first push block 115. The precise matching of the plug rod 118 and the socket enables the second push block to stably move along a predetermined trajectory when subjected to thrust, further improving the stability of the overall operation of the mold. In addition, the material selection and surface treatment process of the connecting rod are also carefully designed to cope with the wear and corrosion problems in a long-term high-intensity working environment, thereby extending the service life of the mold.

[0047] like Figure 1 , 3 As shown, a first mounting block 103 is provided below the second mold 102, a third movable groove is provided on the first mounting block 103, a second movable plate 109 is provided in the third movable groove, a second cylinder is installed on the first mounting block 103, a second push block is provided on the piston rod of the second cylinder, a second groove corresponding to the second push block is provided on the second movable plate 109, and a second dividing blade 110 is connected to the second movable plate 109; a third guide block is provided on the side wall of the second push block, a third guide groove corresponding to the third guide block is provided on the inner wall of the second groove, and the third guide block and the third guide groove are inclinedly arranged.

[0048] like Figure 1 , 8 As shown, a second mounting block 104 is provided on the side wall of the first mold 101, a fourth movable groove is provided on the second mounting block 104, a third movable plate 120 is provided in the fourth movable groove, a third cylinder is installed on the second mounting block 104, a third push block is provided on the piston rod of the third cylinder, a third groove corresponding to the third push block is provided on the third movable plate 120, and a third dividing blade 121 is connected to the third movable plate 120; a fourth guide block is provided on the side wall of the third push block, a fourth guide groove corresponding to the fourth guide block is provided on the inner wall of the third groove, and the fourth guide block and the fourth guide groove are inclinedly arranged.

[0049] A third mounting block is disposed on the other side wall of the first mold 101 . The structure of the third mounting block is the same as that of the second mounting block 104 . The fourth cylinder is disposed on the third mounting block.

[0050] The moving mode of the second movable plate 109 and the third movable plate 120 is the same as the moving mode of the first movable plate 105. When the hard material is injected, the first cylinder 116 pushes the first split blade 107 to move inside the mold cavity, and the second cylinder, the third cylinder and the fourth cylinder respectively drive the second split blade 110, the third split blade 121 and the fourth split blade 122 to move synchronously, so that the first mold cavity is formed into a closed space, so that the hard material is injected separately. After the injection molding of the hard material is completed, the first cylinder 116, the second cylinder, the third cylinder and the fourth cylinder drive the first split blade 107, the second split blade 110, the third split blade 121 and the fourth split blade 122 to move away from and move to a predetermined position, and the second mold cavity is opened to perform the injection molding of soft glue. Through this structural design, the mold can be quickly converted to the soft glue injection molding mode after the injection molding of the hard material is completed, which greatly improves the production efficiency. At the same time, the design of the split blade makes the material filling more uniform, and the injection molding accuracy is significantly improved. This versatility of the mold makes it show unique advantages when producing multi-layer composite materials. Inside the mold, the precise matching of each blade ensures uniform distribution of the material during the injection molding process, avoiding structural defects caused by uneven materials. At the same time, the rapid mold conversion mechanism reduces downtime, significantly improves production efficiency, and meets the market's demand for high-efficiency and high-quality products. The optimized mold design is not only suitable for mass production, but also performs well in small-batch diversified production, winning greater market competitiveness for the company.
