Description
Technical Field
[0001] This utility model relates to the technical field of automotive lamp injection molding equipment, specifically a heating device for trimming the material residue of automotive lamp injection molding housings. Background Technology
[0002] In the production process of automotive headlight injection molded housings, trimming the material residue is an important step. Traditional trimming methods often use heating devices to heat the material residue trimming pliers, which makes the trimming more stable, prevents material residue from springing back, and avoids the plastic parts from breaking. However, existing heating devices usually insert the material residue trimming pliers directly into the pre-designed heating holes of the heating device. During the insertion and removal of the material residue trimming pliers, the pliers are prone to falling out, posing a risk of burns to personnel. Moreover, if the trimming pliers are not inserted accurately, the heat will not be distributed evenly during the conduction process, which can easily cause local overheating of the blade, resulting in unstable trimming results. Therefore, this utility model proposes a heating device for the material residue trimming pliers of automotive headlight injection molded housings to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a heating device for trimming the stub of a car headlight injection molded housing, in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a heating device for trimming the slag of an injection-molded car headlight housing, comprising...

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The placement platform, docking block, adjusting groove, and flat plate assembly structure provide a stable foundation for the trimmer pliers. Furthermore, the timing block and arc-shaped plate structure securely engage with the trimmer pliers, ensuring stable insertion into the heating hole. This precise and stable placement allows for more even heat distribution during the transfer of heat to the pliers, preventing localized overheating of the blades and improving the stability of the trimming effect. Simultaneously, the adjusting rod at the bottom of the flat plate engages with the locking block, preventing the trimmer pliers from detaching from the heating hole and enhancing safety during use. Through the coordinated structure of the timing block, inclined block, sliding rod, adjusting rod, and trimmer pliers body, gripping the handle of the trimmer pliers body pushes the inclined block to slide along the side of the sliding rod via the timing block. The inclined block presses down on the adjusting rod, disengaging it from the locking block for quick and easy access to the trimmer pliers. The structure is simple, easy to use, and effectively avoids the risk of the trimmer pliers falling during the heating process. Attached Figure Description

[0021] The protective shell 1 has heating holes 2 on its side. A placement platform 3 is fixedly connected to the side of the protective shell 1. A docking block 4 is installed on the top of the placement platform 3. A sliding groove 5 is opened on the top of the docking block 4. An adjustment groove 6 is opened on the top of the docking block 4. A locking block 7 is set on the top of the adjustment groove 6. A flat plate 8 is slidably set on the top of the sliding groove 5. A track groove 9 is opened on the top of the flat plate 8. An adjustment connecting rod 12 is hinged to the bottom of the flat plate 8. A tension spring 13 is fixedly installed on the top of the adjustment connecting rod 12, and the end of the tension spring 13 away from the adjustment connecting rod 12 is fixedly connected to the bottom of the flat plate 8.
[0022] A temperature control wire 14 is fixedly connected to the side of the protective shell 1, and a heat insulation adhesive 15 is fixedly installed on the inside of the protective shell 1. A heating shell 16 is connected to the inside of the heat insulation adhesive 15, and a heating tube 17 is installed on the inside of the heating shell 16. The multi-layer heat insulation protection design of the heating shell 16, the heat insulation adhesive 15, and the protective shell 1 effectively prevents burns to operators and safety accidents caused by equipment malfunctions such as overheating and short circuits, providing operators with a safe and reliable working environment.
[0023] A limiting block 18 is fixedly installed at the bottom of the plate 8. The limiting block 18 is slidably set inside the slide groove 5. An extension strip 19 is fixedly connected to the side of the plate 8. An arc-shaped piece 20 is fixedly connected to the side of the extension strip 19. A pliers body 21 is placed on the top of the plate 8. The scissors of the pliers body 21 are in contact with the top of the arc-shaped piece 20. The synchronizing block 24 and the arc-shaped piece 20 are locked and fixed to the pliers body 21. The pliers can be stably inserted into the heating hole 2. The pliers are inserted accurately and stably. The heat is more evenly distributed during the conduction to the scissors. The structure of the arc-shaped piece 20 can seal the heating hole 2 to prevent foreign objects from entering the heating hole 2 and affecting the conduction efficiency of internal heating. The structure is simple and the design is reasonable.
[0024] A guide rod 10 is fixedly installed on the side of the track groove 9, and two sets of slide rods 11 are fixedly installed on the side of the track groove 9. An inclined block 22 is slidably arranged on the side of the slide rod 11, and the inclined block 22 can slide in contact with the adjusting connecting rod 12. A synchronization block 24 is fixedly installed on the top of the inclined block 22. A compression spring 23 is sleeved on the side of the slide rod 11. When the handle of the pliers body 21 is gripped, the handle will push the inclined block 22 to slide on the side of the slide rod 11 through the synchronization block 24. The inclined block 22 slides down and presses the adjusting connecting rod 12, causing the adjusting connecting rod 12 to disengage from the locking block 7, which facilitates quick access to the pliers. The structure is simple and easy to use, and effectively avoids the risk of the pliers falling during the heating process.
[0025] In practical use: First, when heating the pliers body 21 is required, place the pliers on top of the plate 8. The synchronizing block 24 will push the pliers handle, causing the pliers to open. Then, push the pliers so that the scissor part contacts the arc-shaped piece 20 and pushes the arc-shaped piece 20 into the heating hole 2 for heating. At this time, the adjusting rod 12 at the bottom of the plate 8 is pushed by the tension spring 13, and the adjusting rod 12 engages with the locking block 7. The structure of the plate 8 is thus fixed, and the pliers will not detach from the heating hole 2. When the pliers need to be used, grip the handle of the pliers body 21. The handle will push the inclined block 22 to slide on the side of the slide rod 11 through the synchronizing block 24. During the sliding process, the inclined block 22 contacts the adjusting rod 12 and presses down the adjusting rod 12. The bottom of the adjusting rod 12 is lifted, and the adjusting rod 12 disengages from the locking block 7, releasing the restriction of the plate 8. Then, the pliers can be taken out for use. The structure is simple and the operation is convenient.
