Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically a guide mechanism for lamp injection molds. Background Technology

[0002] Injection molds are molds used in the injection molding process. They are tools used to inject molten plastic into the mold cavity, which then cools and solidifies to form the desired plastic product. Injection molds consist of a fixed mold, a moving mold, and a demolding assembly. The demolding assembly can move and push the finished product out of the moving mold. Injection molds are used in the manufacture of lamps to assist in the production of lamp housings for subsequent assembly.

[0003] Currently, in some injection molds used for lighting production, the demolding components are limited during use, allowing the finished product to be pushed out via the top plate. Afterward, with the help of springs, the demolding components can reset. However, after prolonged use, the springs reach their lifespan limit, requiring disassembly and replacement. Since some demolding components are located inside the moving mold, replacing the springs requires disassembling the entire mold. This process is not only cumbersome, but also requires subsequent readjustment of the positions and angles between the moving mold, fixed mold, and demolding components. This process is time-consuming and can affect subsequent use. Utility Model Content

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.

[0024] Please see Figure 1-7As shown, a guiding mechanism for a lamp injection mold includes a fixed mold body 1, a moving mold body 5, a limiting rod 8, an extension rod 16 fixedly connected to the mold body 1, and a movable plate 2 slidably sleeved on the surface of the extension rod 16. A back plate 3 is fixedly connected to the surface of the movable plate 2, and a fixed frame 4 is fixedly connected to the surface of the back plate 3. The moving mold body 5 is fixedly connected to the fixed frame 4. An injection groove is formed on the surface of the moving mold body 5. Raw material is injected into the injection groove through the fixed mold body 1 so that the raw material can be formed in the injection groove. This is a mature existing technology and will not be described in detail here. A demolding mechanism 6 is provided inside the fixed frame 4. A connecting frame 7 is provided on the surface of the demolding mechanism 6. The inner wall of the connecting frame 7 is slidably connected to the surface of the fixed frame 4. The limiting rod 8 slides through the fixed frame 4 to adjust the position of the demolding mechanism 6. The limiting rod 8 and the extension rod All 16 are fixed to the injection molding equipment. This is a mature existing technology and will not be described in detail here. Guide mechanisms 9 are installed on both sides of the surface of the moving plate 2. Springs 10 are provided on the surface of the guide mechanisms 9. Springs 10 can assist the resetting of the connecting frame 7. Hollow box 12 is fixedly passed through the surface of the moving plate 2. T-shaped plate 13 is fixedly connected to the surface of the connecting frame 7. The surface of T-shaped plate 13 is slidably connected to the inner wall of hollow box 12. Ventilation cylinders 14 are fixedly passed through both sides of the surface of hollow box 12. Sealing mechanism 15 is installed inside the ventilation cylinder 14. Air supply pipes 17 are connected to both sides of the surface of hollow box 12. Exhaust hood 18 is fixedly connected to the surface of the connecting frame 7. One end of the air supply pipe 17 is connected to the exhaust hood 18. The exhaust hood 18 and the air supply pipe 17 are used together to clean the surface of rectangular plate 61 through the flow of air.

[0025] The demolding mechanism 6 includes a rectangular plate 61, a smooth rod 62, and a top plate 63. The surface of the rectangular plate 61 is slidably connected to the inner wall of the fixed frame 4. The smooth rod 62 is fixedly connected to the surface of the rectangular plate 61. The top plate 63 is fixedly connected to one end of the smooth rod 62. The connecting frame 7 is fixedly sleeved on the surface of the rectangular plate 61. One end of the limiting rod 8 slides through the fixed frame 4 and contacts the surface of the rectangular plate 61. The surface of the top plate 63 contacts the inner wall of the injection molding tank. The smooth rod 62 slides through the fixed frame 4. The hydraulic equipment in the injection molding device drives the moving plate 2 to move. During this process, the limiting rod 8 passes through the fixed frame 4. When the limiting rod 8 contacts the rectangular plate 61, the moving plate 2 continues to move. The rectangular plate 61 moves inside the fixed frame 4 due to the obstruction of the limiting rod 8. At this time, the smooth rod 62 can drive the top plate 63 to move. The top plate 63 moves accordingly and pushes out the molded lamp housing in the injection molding tank for unloading.

[0026] The guiding mechanism 9 includes a guide rod 91, a locking block 92, a rotating shaft 93, and a positioning plate 94. The guide rod 91 slides through the surface of the moving plate 2. The locking block 92 is fixedly connected to one end of the guide rod 91 and slides through the surface of the connecting frame 7. The rotating shaft 93 is fixedly connected to the surface of the locking block 92. The positioning plate 94 is rotatably sleeved on the surface of the rotating shaft 93, and the surface of the positioning plate 94 contacts the surface of the connecting frame 7. The spring 10 is sleeved on the surface of the guide rod 91. When the operator replaces the spring 10, they can first rotate the positioning plate 94 and pull the guide rod 91. 2 can drive the positioning plate 94 to move, thereby limiting the contact of the connecting frame 7. The operator can pull the guide rod 91 and remove the spring 10 for replacement to ensure the subsequent use of the spring 10. The top of the connecting frame 7 is slidably connected to the reinforcing rod 11, which slidably passes through the locking block 92. The top of the reinforcing rod 11 is fixedly connected to the horizontal plate, and the top of the horizontal plate is provided with a bolt. The bolt thread passes through the top of the connecting frame 7. The operator can fix the position of the reinforcing rod 11 by setting the bolt, so as to increase the stability of the locking block 92 position by the reinforcing rod 11.

[0027] The sealing mechanism 15 includes a bracket 151, a slide rod 152, and a sealing block 153. The bracket 151 is fixedly connected to the inner wall of the vent 14. The slide rod 152 slides through the surface of the bracket 151. The sealing block 153 is fixedly connected to one end of the slide rod 152. The surface of the sealing block 153 is in contact with the inner wall of the vent 14. When the T-shaped plate 13 moves, under the action of atmospheric pressure, the sealing block 153 moves toward the position of the bracket 151. At this time, air can be discharged into the interior of the hollow box 12 through the vent 14. When the T-shaped plate 13 moves in the opposite direction, the sealing block 153 moves under pressure and blocks the vent 14. At this time, the air inside the hollow box 12 is discharged through the air supply pipe 17 and the exhaust hood 18 and cleans the surface of the rectangular plate 61 to reduce the possibility that impurities attached to the surface of the rectangular plate 61 will affect the stability of the rectangular plate 61 after reset.

[0028] The upper and lower surfaces of the movable plate 2 are fixedly connected with protruding plates 19. The width of the protruding plates 19 is greater than the length of the air cylinder 14 extending out of the surface of the hollow box 12. By setting the protruding plates 19, the possibility of the movable plate 2 contacting the injection molding device and causing the air cylinder 14 to be blocked when it moves can be reduced.

[0029] Working principle: The operator injects the raw material into the injection tank through the fixed mold body 1. After the raw material is formed in the injection tank, the hydraulic equipment in the injection molding machine can drive the moving plate 2 to move along the extension rod 16. This is a mature existing technology and will not be described in detail here. When the moving plate 2 moves, the limiting rod 8 passes through the fixed frame 4 and abuts against the rectangular plate 61. The rectangular plate 61 drives the connecting frame 7 and the top plate 63 to move. The movement of the top plate 63 can push out the lamp housing formed in the injection tank for unloading. At the same time, the spring 10 is stretched by force, and the guide rod 91 guides the movement of the connecting frame 7. The connecting frame 7 drives the T-shaped plate 13 to move. When the sealing block 153 releases the blockage of the vent 14, outside air is injected into the interior of the hollow box 12 through the vent 14. Then, under the action of the spring 10, the top plate 63 moves and resets to prepare for subsequent injection molding. The connecting frame 7 moves and drives the T-shaped plate 13 to move. The air inside the hollow box 12 is discharged to the exhaust hood 18 through the air supply pipe 17. Thus, the debris on the surface of the rectangular plate 61 can be cleaned through the exhaust hood 18 to increase the cleanliness of the rectangular plate 61 surface. This reduces the amount of debris adhering to the surface of the rectangular plate 61 so that the top plate 63 can be reset and used in subsequent applications.

[0030] Workers can periodically disassemble and replace the spring 10 to ensure its performance. During this process, workers first loosen the bolts to release the limit on the horizontal plate. Then, workers can pull the horizontal plate to remove the reinforcing rod 11. The limit of the reinforcing rod 11 on the locking block 92 is released. Workers can then rotate the positioning plate 94 and pull the guide rod 91 to remove and replace the spring 10.
