Technical Field

[0001] This utility model relates to the field of automotive rearview mirror processing technology, and in particular to a molding die for a rearview mirror. Background Technology

[0002] Car rearview mirrors are core components for ensuring driving safety, including interior rearview mirrors (flat mirrors for accurate distance judgment) and exterior rearview mirrors (convex mirrors for reducing blind spots). Modern technology has enabled functions such as electric adjustment, heating and defrosting, and anti-glare.

[0003] Car rearview mirror housings are usually made of engineering plastics. During production, molding dies are used to injection mold the rearview mirror housings. After injection molding, the injection molded housings usually need to be cooled and shaped. However, most of the existing molding dies use natural cooling, which is slow and greatly reduces the injection molding efficiency of rearview mirror housings. Utility Model Content

The outlet end of the return pipe is fixedly connected to the inner wall of the storage tank, and the surface of the return pipe is fixedly connected to the inner wall of the fixing frame. The inlet end of the return pipe is fixedly connected to the inner wall of the heat exchange box.

[0007] Preferably, the refrigeration assembly consists of a temperature-conducting plate, a semiconductor refrigeration chip, a fan cover, and a cooling fan. The temperature-conducting plate is fixedly connected to the inner wall of the liquid storage tank, the semiconductor refrigeration chip is fixedly connected to the inner wall of the temperature-conducting plate, the fan cover is fixedly connected to the bottom surface of the liquid storage tank, and the cooling fan is fixedly connected to the inner wall of the fan cover.

[0008] Preferably, the stirring mechanism consists of a fixed shaft and a stirring paddle, the fixed shaft being rotatably connected to the inner wall of the liquid storage tank, and the inner wall of the stirring paddle being fixedly connected to the surface of the fixed shaft.

[0009] Preferably, the drive assembly consists of a servo motor, a drive wheel, a transmission belt, and a driven wheel.

[0011] Preferably, there are multiple support columns, and all of the multiple support columns are located on the bottom surface of the fixed platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The rearview mirror uses a molding die. An electric push rod is activated to push the upper and lower molds together for injection molding. After injection molding, a cooling component is activated to lower the temperature of the coolant inside the storage tank. A drive component is activated to drive a stirring mechanism to rotate along the inner wall of the storage tank, thus stirring the coolant to increase the cooling speed. A water circulation mechanism is activated to draw low-temperature coolant and circulate it along the inside of the heat exchange box. Through the heat conduction effect of the heat exchange box, the lower mold and the injection molded part can be quickly cooled and shaped. This achieves the goal of facilitating rapid cooling and shaping of the injection-molded rearview mirror housing, avoiding the problem of significantly reduced injection molding efficiency of the rearview mirror housing due to the fact that most existing molding dies rely on natural cooling.

The fixed frame 6 is rectangular and made of metal, which provides higher strength, makes it less prone to deformation and damage under stress, and more durable. An electric push rod 7 is fixedly connected to the inner wall of the fixed frame 6. An upper mold 8 is fixedly connected to the output end of the electric push rod 7. A water circulation mechanism is installed inside the liquid storage tank 3, consisting of a suction pipe 9, a return pipe 10, and a water pump 11.

The suction pipe 9 is fixedly connected to the inner wall of the fixing frame 6, and the liquid outlet end of the suction pipe 9 is fixedly connected to the inner wall of the heat exchange box 4. The liquid outlet end of the return pipe 10 is fixedly connected to the inner wall of the storage tank 3, and the surface of the return pipe 10 is fixedly connected to the inner wall of the fixing frame 6. The liquid inlet end of the return pipe 10 is fixedly connected to the inner wall of the heat exchange box 4. It is used to draw low-temperature coolant for circulation, which is convenient for heat exchange and cooling of injection molded parts in conjunction with the heat exchange box 4. The storage tank 3 is equipped with a refrigeration component, which consists of a temperature guide plate 12, a semiconductor cooling chip 13, a fan shroud 14 and a cooling fan 15. The temperature guide plate 12 is fixedly connected to the inner wall of the storage tank 3, the semiconductor cooling chip 13 is fixedly connected to the inner wall of the temperature guide plate 12, the fan shroud 14 is fixedly connected to the bottom surface of the storage tank 3, and the cooling fan 15 is fixedly connected to the inner wall of the fan shroud 14. It is used to reduce the temperature of the coolant and improve the cooling and shaping speed. The storage tank 3 is equipped with a stirring mechanism, and the bottom surface of the storage tank 3 is equipped with a drive component.

[0017] Specifically, the stirring mechanism consists of a fixed shaft 16 and a stirring paddle 17. The fixed shaft 16 is rotatably connected to the inner wall of the liquid storage tank 3, and the inner wall of the stirring paddle 17 is fixedly connected to the surface of the fixed shaft 16. It is used to stir the coolant, which facilitates the mixing of high-temperature coolant and low-temperature coolant and improves the cooling efficiency.

[0018] Specifically, the drive assembly consists of a servo motor 18, a drive wheel 19, a transmission belt 20, and a driven wheel 21.

The raw material is then injected into the lower mold 5 through the injection port located above the upper mold 8 to form the rearview mirror housing. After injection molding, the thermoelectric cooler 13 is activated to absorb and release heat. The heat-absorbing end of the thermoelectric cooler 13 absorbs heat from the temperature-conducting plate 12 and the internal coolant tank 3, thereby reducing the temperature of the coolant inside the coolant tank 3. Simultaneously, the cooling fan 15 is activated to dissipate heat from the heat-releasing end of the thermoelectric cooler 13. The servo motor 18 is then activated to drive the active... The rotation of wheel 19 and transmission belt 20, through the meshing of transmission belt 20 and driven wheel 21, drives fixed shaft 16 to rotate along the inner wall of liquid storage tank 3. The rotation of fixed shaft 16 drives stirring paddle 17 to rotate along the inner wall of liquid storage tank 3, thereby stirring the coolant to increase the cooling speed. The water pump 11 is started to draw low-temperature coolant into heat exchange box 4 through suction pipe 9. Through the heat conduction effect of heat exchange box 4, the lower mold 5 and injection molded parts can be quickly cooled and shaped. At the same time, the coolant that has completed heat exchange flows back to liquid storage tank 3 through return pipe 10, thus performing circulating cooling.
