[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, an ignition coil guard assembly injection mold described in an embodiment of the utility model includes an injection molding machine body 1; a bottom plate 12 is fixedly connected to the top of the injection molding machine body 1; a motor 13 is fixedly connected to the top of the bottom plate 12; a rotating rod 14 is fixedly connected to the output end of the motor 13; a plurality of fan blades 15 are fixedly connected to the middle of the rotating rod 14; the plurality of fan blades 15 are equidistantly distributed along the radius of the rotating rod 14; a protective shell 16 is fixedly connected to the top of the bottom plate 12; two air ducts 17 are connected to the middle of the protective shell 16; the two air ducts 17 are symmetrically arranged; the middle of the air duct 17 is provided with a plurality of An air outlet 18 is provided; the air outlet 18 is directly opposite to the output end of the injection molding machine body 1; the middle of the air outlet 18 is connected with a shunt pipe 19; the shunt pipe 19 extends to the edge of the output end of the injection molding machine body 1. When the injection molding machine body 1 is started, the ignition coil guard can be injected. At this time, after the injection molding is completed, the cooling system carried by the injection molding machine body 1 will spray the injection casting with coolant, so that the mold can be quickly cooled and formed. At this time, the residual cooling will be adsorbed on the surface of the injection molding module. At this time, the adsorption of water droplets may affect the injection molding of the mold. When the cooling system sprays the injection molding module with coolant, the cooling system will spray the cooling system with coolant. When cooling liquid, the motor 13 can be started synchronously. With the start of the motor 13, the output end of the motor 13 will drive the rotating rod 14 to rotate synchronously. At this time, with the rotation of the rotating rod 14, the plurality of fan blades 15 will also rotate synchronously. At this time, the rotation of the plurality of fan blades 15 will generate a certain wind force. At this time, the wind force generated by the rotation of the rotating rod 14 will enter the interior of the wind duct 17 as the wind duct 17 is connected. At this time, the wind force will flow along the contour of the wind duct 17. When the wind force passes through the air outlet 18, the wind force will penetrate the air outlet 18 and enter the interior of the shunt pipe 19. At this time, the wind force will continue to flow through the plurality of shunt pipes 19. The injection molding module of the injection molding machine body 1 is blown to blow away the remaining water droplets adsorbed on the surface of the injection molding module, or blow it dry. Through the above structure, multiple shunt pipes 19 can continuously blow air to the output end of the injection molding machine body 1, thereby reducing the surface of the injection molding module absorbing too much coolant, thereby affecting the subsequent injection molding. At the same time, by blowing air to the output end of the injection molding machine body 1 through multiple shunt pipes 19, dust or impurities adsorbed on the output end surface of the injection molding machine body 1 can be reduced, thereby causing the subsequent molding mold surface to be uneven, affecting the integrity of the finished product.

[0024] like Figures 1 to 3As shown, the interior of the plurality of shunt pipes 19 is fixed with two first connecting rods 2; a fixing block 21 is fixedly connected to the middle of the two first connecting rods 2; an auger 22 is rotatably connected to the side wall of the fixing block 21; a second connecting rod 23 is fixedly connected to the end of the auger 22; a support rod 24 is fixedly connected to the end of the second connecting rod 23; a groove 25 is provided in the middle of the support rod 24; a rotating ring 26 is rotatably connected to the middle of the groove 25; a plurality of third connecting rods 27 are fixedly connected to the middle of the rotating ring 26; a plurality of the third connecting rods 27 are equidistantly distributed along the radius of the rotating ring 26; the ends of the plurality of the third connecting rods 27 are fixedly connected with air bags 28, and when working, a certain amount of desiccant is filled in the air bags 28, and at this time, when the wind force generated by the rotation of the plurality of fan blades 15 enters the interior of the shunt pipe 19 through the air outlet 18, the blowing of the wind force will drive the auger 22 to rotate synchronously, and at this time, with the rotation of the auger 22, the second connecting rod 23 can be driven to rotate, At this time, the rotating second connecting rod 23 will synchronously drive the support rod 24 to rotate. At this time, with the rotation of the support rod 24, the groove 25 in the middle of the support rod 24 can be driven to rotate irregularly. At this time, through the rotation of the groove 25, multiple third connecting rods 27 and the air-permeable bag 28 can be driven to rotate synchronously. At this time, multiple air-permeable bags 28 will continuously rotate at the edge of the output end of the injection molding machine body 1. Through the above structure, the air-permeable bag 28 can be continuously rotated inside the injection molding machine body 1, thereby driving the desiccant inside the air-permeable bag 28 to continuously rotate inside the injection molding machine body 1. By rotating multiple groups of desiccant inside the injection molding machine body 1 for a long time, the inside of the injection molding machine body 1 can be continuously kept dry, thereby reducing the adsorption of excess coolant on the surface of the output end of the injection molding machine body 1. At the same time, through the continuous rotation of multiple third connecting rods 27, the wind force blowing inside the injection molding machine body 1 can be further increased, thereby further reducing water stains inside the injection molding machine body 1.

[0025] like Figure 1 and Figure 5As shown, the middle parts of the two air ducts 17 are both sleeved with a ring 31; the middle part of the ring 31 is fixedly connected with a connecting piece 3; the end of the connecting piece 3 is fixedly connected to the side wall of the injection molding machine body 1. During operation, the wind force generated by the rotation of the rotating rod 14 will flow inside the air duct 17. At this time, the wind force will drive the multiple groups of augers 22 to rotate. At this time, the rotating augers 22 will produce a certain shaking. As time goes by, the air duct 17 continues to shake and may fall off. At this time, a connecting piece 3 is sleeved on the middle part of the air duct 17, and then the connecting piece 3 and the side wall of the injection molding machine body 1 are connected together through the ring 31. At this time, the air duct 17 can be fixed. Through the above structure, the air duct 17 and the side wall of the injection molding machine body 1 can be connected through the ring 31, so that the air duct 17 is supported, which reduces the falling off of the air duct 17 caused by long-term shaking and increases the stability of the air duct 17.

[0026] like Figure 1 and Figure 2 As shown, a plurality of heat dissipation holes 4 are provided in the middle of the protective shell 16; a mesh plate 41 is fixedly connected in the middle of the plurality of heat dissipation holes 4. When working, the rotating rod 14 works in the protective shell 16 for a long time, which will generate a large amount of heat. The heat generated at this time will be discharged through the heat dissipation holes 4, and the interior of the protective shell 16 can be ventilated through the heat dissipation holes 4. At this time, by arranging the mesh plate 41 in the middle of the heat dissipation holes 4, it is possible to reduce the dust or impurities from entering the mesh plate 41 through the heat dissipation holes 4. Through the above structure, on the one hand, the temperature inside the protective shell 16 can be reduced, and the motor 13 can be reduced from working in a high temperature state for a long time, resulting in damage. On the other hand, it is possible to reduce the dust or impurities from entering the protective shell 16, resulting in excessive accumulation of dust or impurities in the protective shell 16, which may affect the rotation of the rotating rod 14.

[0027] like Figure 4 As shown, the inner wall of the air duct 17 is hinged with multiple groups of through rods 5; the multiple groups of through rods 5 are equidistantly distributed along the contour of the air duct 17. During operation, when the wind force generated by the rotation of the fan blades 15 enters the interior of the air duct 17, it can drive the multiple through rods 5 inside the air duct 17 to swing. At this time, the swing of the multiple through rods 5 can clear the interior of the air duct 17. Over time, some dust or impurities will accumulate inside the air duct 17, and these dusts may cause the air outlet 18 to be blocked, thereby affecting the blowing of the output end of the injection molding machine body 1. At this time, the dust blocked inside the air duct 17 can be cleared by the swing of the multiple through rods 5. Through the above structure, the blockage caused by excessive dust accumulation inside the air duct 17 can be reduced.

[0028] like Figure 5As shown, both side walls of the collar 31 are fixedly connected with a plurality of brushes 6; the plurality of brushes 6 are equidistantly distributed along the radius of the collar 31. When working, the shaking of the air duct 17 can drive the plurality of brushes 6 to shake synchronously. At this time, the shaking of the plurality of brushes 6 can scrub the surface of the air duct 17. Through the above structure, the absorption of excessive dust or impurities on the surface of the air duct 17 can be reduced, thereby reducing the dust or impurities from entering the interior of the air duct 17 through the air outlet 18.

[0029] like Figure 3 As shown, the support rod 24 is made of a lightweight material with a certain strength. The above arrangement can reduce the possibility of breakage when the support rod 24 drives the multiple air-permeable bags 28 to rotate.

[0030] During operation, when the injection molding machine body 1 is started, the ignition coil protective kit can be injection molded. At this time, when the injection molding is completed, the cooling system carried by the injection molding machine body 1 will spray coolant on the injection casting, so that the mold can be quickly cooled and formed. At this time, the residual cooling will be adsorbed on the surface of the injection molding module. At this time, the adsorption of water droplets may affect the injection molding of the mold. When the cooling system sprays coolant on the injection molding module, the motor 13 can be started synchronously. With the start of the motor 13, the output end of the motor 13 will drive the rotating rod 14 to rotate synchronously. At this time, with the rotation of the rotating rod 14, the multiple fan blades 15 will also rotate synchronously. At this time, the rotation of the multiple fan blades 15 will generate a certain wind force. At this time, the wind force generated by the rotation of the rotating rod 14 will follow the wind The fan 17 is connected to the air duct 17 and enters the interior of the air duct 17. At this time, the wind will flow along the contour of the air duct 17. When the wind passes through the air outlet hole 18, the wind will penetrate the air outlet hole 18 and enter the interior of the shunt pipe 19. At this time, the injection molding module of the injection molding machine body 1 is continuously blown through the multiple shunt pipes 19, so that the residual water droplets adsorbed on the surface of the injection molding module can be blown off or dried. A certain amount of desiccant is filled in the air bag 28. At this time, when the wind generated by the rotation of the multiple fan blades 15 enters the interior of the shunt pipe 19 through the air outlet hole 18, the blowing of the wind will drive the auger 22 to rotate synchronously. At this time, as the auger 22 rotates, the second connecting rod 23 can be driven to rotate. At this time, the rotating second connecting rod 23 will synchronously drive the support The rod 24 rotates, and as the support rod 24 rotates, the groove 25 in the middle of the support rod 24 can be driven to rotate irregularly. At this time, the rotation of the groove 25 can drive multiple third connecting rods 27 and the air-permeable bags 28 to rotate synchronously. At this time, the multiple air-permeable bags 28 will continuously rotate at the edge of the output end of the injection molding machine body 1, and the wind force generated by the rotation of the rotating rod 14 will flow inside the air duct 17. At this time, the wind force will drive multiple groups of augers 22 to rotate. At this time, the rotating augers 22 will produce a certain amount of shaking. As time goes by, the air duct 17 continues to shake and may fall off. At this time, a connector 3 is set in the middle of the air duct 17, and then the connector 3 is connected to the side wall of the injection molding machine body 1 through a ring 31. Together, the air duct 17 can be fixed at this time. The rotating rod 14 works for a long time inside the protective shell 16, which will generate a lot of heat. The heat generated at this time will be discharged through the heat dissipation holes 4. At the same time, the interior of the protective shell 16 can be ventilated through the heat dissipation holes 4. At this time, a grid plate 41 is arranged in the middle of the heat dissipation holes 4 to reduce dust or impurities from entering the inside of the grid plate 41 through the heat dissipation holes 4. When the wind force generated by the rotation of the fan blades 15 enters the inside of the air duct 17, it can drive the multiple through rods 5 inside the air duct 17 to swing. At this time, the swing of the multiple through rods 5 can clear the inside of the air duct 17. Over time, some dust or impurities will accumulate inside the air duct 17. These dust may cause the air outlet 18 to be blocked.This affects the blowing of the output end of the injection molding machine body 1. At this time, the dust blocked inside the air duct 17 can be cleared by swinging the multiple through rods 5. The shaking of the air duct 17 can drive the multiple brushes 6 to shake synchronously. At this time, the shaking of the multiple brushes 6 can scrub the surface of the air duct 17.
