Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds for automobile headlights, and more specifically, particularly relates to an injection mold for automobile headlights. Background Art

[0002] Headlight molds are an important part of the automobile manufacturing industry. With the continuous expansion of the automobile market and the continuous progress of automobile manufacturing technology, the headlight mold industry has also developed rapidly. Headlight molds are used to manufacture vehicle headlights, taillights, turn signals and other headlights, and their quality and precision directly affect the manufacturing and use effects of headlights.

[0003] In the current injection mold for automobile headlights, when processing automobile headlights, after the mold is filled, it needs to be cooled before demolding. During the injection process, cooling is usually carried out by cooling water channels. However, the cooling water in the cooling water channels is very easy to heat itself during continuous circulation, resulting in a decline in cooling performance. In the case where the cooling speed and degree of the thick-walled area are insufficient, it will cause the surface of the injected headlight to sink, and the produced headlights are prone to shrinkage and warping. At the same time, in small-scale headlight production, demolding often requires manual removal from the mold, which is time-consuming and laborious, and the efficiency is low.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an injection mold for automobile headlights is provided, in order to achieve a more practical value purpose. Content of the Utility Model

[0022] Embodiment:

[0023] As shown in Figure 1 to Figure 4 shown:

[0024] The present utility model provides an injection mold for automobile headlights, including a moving die 1 and a fixed die 2. A forming groove 3 is opened on one side of the moving die 1 adjacent to the fixed die 2. A cooling groove 5 is opened inside the moving die 1. A cooling box 4 is arranged inside the cooling groove 5. Two pairs of heat dissipation fans are arranged in the cooling groove 5. A forming block 6 is movably connected to the position corresponding to the forming groove 3 on one side of the fixed die 2. A injection block 7 is fixedly connected to the side of the forming block 6 away from the fixed die 2. Two pairs of injection holes 8 are opened on the side of the injection block 7 away from the forming block 6. An activity groove 9 is arranged inside the fixed die 2. A connecting block 10 is fixedly connected to the position of the forming block 6 facing the activity groove 9. A pair of electric telescopic rods 11 are fixedly connected to one side of the activity groove 9. The other ends of the pair of electric telescopic rods 11 are fixedly connected to the side of the connecting block 10 facing the activity groove 9.

[0025] Among them, the two pairs of heat dissipation fans each include a heat dissipation housing 12, a rotating shaft 13, a fan blade 14 and a rotating motor 15. An equipment groove 16 is opened on one side of the heat dissipation housing 12, and the equipment groove 16 penetrates both sides of the heat dissipation housing 12. A support plate 17 is fixedly connected to one side of the equipment groove 16. The support plate 17 is rotatably connected to the rotating shaft 13. A fan blade 14 is fixedly sleeved on the outer side of the rotating shaft 13. The rotating motor 15 is located on the other side of the support plate 17. One end of the rotating shaft 13 penetrates the support plate 17 and is in transmission connection with the rotating motor 15.

[0026] Among them, a ventilation groove 18 is formed on one side of the support plate 17, and the ventilation groove 18 penetrates through the other side of the support plate 17. A heat dissipation groove 19 is formed at a position of the moving mold 1 close to the equipment groove 16, and the heat dissipation groove 19 is communicated with the cooling groove 5. A filter screen 20 is fixedly connected to the heat dissipation groove 19.

[0027] Among them, mounting blocks 21 are fixedly connected to the sides of the moving mold 1 and the fixed mold 2 away from each other. The arrangement of the mounting blocks 21 facilitates the installation of the moving mold 1 and the fixed mold 2.

[0028] Among them, two pairs of injection pipes 26 are formed inside the fixed mold 2. The injection pipes 26 are communicated with the injection holes 8, and the other ends of the injection pipes 26 extend to the outside of the fixed mold 2.

[0029] Among them, docking columns 22 are fixedly connected to the four corners of the side of the moving mold 1 facing the fixed mold 2, and limiting blocks 23 are fixedly connected to the four corners of the side of the fixed mold 2 facing the moving mold 1.

[0030] Among them, a cooling water channel 25 is arranged inside the moving mold 1. The arrangement of the cooling water channel 25 can dissipate heat from the mold.

[0031] The working principle of this embodiment: When the present utility model is in use, the moving mold 1 and the fixed mold 2 are brought closer to each other, and the docking grooves 24 on the docking columns 22 and the limiting blocks 23 are docked, so that the moving mold 1 and the fixed mold 2 are firmly attached together. Subsequently, injection molding is carried out on the molding groove 3 through the injection pipes 26 and the injection holes 8, so that the automotive headlight is formed in the molding groove 3 and the molding block 6. Subsequently, the cooling water channel 25 circulates the cooling water. At the same time, the rotary motor 15 drives the rotating shaft 13 to rotate, and the rotating shaft 13 rotates to drive the fan blades 14 to rotate, and thus the cooling fan continuously dissipates heat from the cooling water channel 25. At the same time, the heat will be discharged through the ventilation groove 18 and the heat dissipation groove 19, ensuring the cooling speed of the thick-walled area and avoiding the phenomena of shrinkage and warping of the headlight. When the automotive headlight is cooled and shaped, the moving mold 1 will separate from the fixed mold 2. Subsequently, the electric telescopic rod 11 will push out the connecting block 10, and the connecting block 10 drives the molding block 6 to move, pushing the molded headlight away from the molding block 6, which is time-saving and labor-saving and improves the production efficiency of the automotive headlight.
