Description

Technical Field

[0001] This utility model relates to injection molding dies. Specifically, it relates to an injection molding die for automotive fog light trim parts. Background Technology

[0002] Injection molding dies for automotive fog light trim parts are precision molds specifically designed for producing decorative components around automotive fog lights. Through injection molding, molten plastic material is injected into the mold cavity, and after cooling and solidification, a fog light trim part with a specific shape and size is formed. The design and manufacturing precision of this mold directly affects the quality, production efficiency, and cost of the trim part.

[0003] The existing external air-cooling components used in the injection molding of automotive fog light trim parts are inefficient and cannot effectively cool the mold. They cannot uniformly and effectively remove the heat emitted by the mold and cool it quickly. Furthermore, during the injection process, air is easily trapped in the melt, forming bubbles. The existing injection molding mold cannot remove these bubbles in time. These bubbles form voids inside the product and create depressions on the surface, significantly reducing product strength, damaging appearance quality, and greatly increasing the defect rate.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses an injection molding die for automotive fog light decorative parts.

[0027] This utility model provides, for example Figure 1-4 The injection molding mold for an automotive fog light trim part shown includes a base 1, with limiting slide rods 2 fixedly connected to both ends of the top of the base 1, and a U-shaped support seat 3 slidably connected between the two limiting slide rods 2. A vibration exhaust mechanism is provided in the cavity of the base 1, and a hydraulic cylinder assembly 4 is fixedly connected between the two ends of the U-shaped support seat 3. A gas cooling chamber 5 is fixedly connected to one end of the hydraulic cylinder assembly 4, and a feeding assembly 6 is fixedly connected to the cavity of the gas cooling chamber 5 through an opening.

[0028] The bottom of the cooling chamber 5 is fixedly connected to the upper mold 7. The top of the inner wall of the U-shaped support 3 is fixedly connected to the drive chamber 8. The top of the drive chamber 8 is fixedly connected to the lower mold 9. The upper mold 7 and the lower mold 9 are provided with cooling circulation chambers 10. A demolding mechanism is fixedly connected inside the drive chamber 8. The tops of the two end limiting slides 2 are respectively fixedly connected to the cooling water inlet assembly 11 and the cooling water outlet assembly 12. The two end outputs of the cooling water inlet assembly 11 are respectively fixedly connected to the inputs of the upper mold 7 and the lower mold 9. The two end inputs of the cooling water outlet assembly 12 are respectively fixedly connected to the outputs of the upper mold 7 and the lower mold 9. The two end side wall outputs of the feeding assembly 6 are fixedly connected to the feeding hoses 13. The two end feeding hoses 13 are fixedly connected to the two end inputs of the upper mold 7. The mechanism utilizes the two end limiting slides. The U-shaped support 3, which is slidably connected between the upper and lower molds 2, is pushed up and down by the vibration exhaust mechanism at the bottom, causing the mold components in the U-shaped support 3 to vibrate. The vibration removes air bubbles from the solution, which are then discharged through the feeding hose 13. The demolding mechanism set in the drive chamber 8 facilitates the demolding of the mold in the lower mold 9. The cooling water inlet component 11 and cooling water outlet component 12 are set to achieve a cooling cycle between the upper mold 7 and the lower mold 9. The mold in the mold groove is quickly cooled through the cooling circulation chamber 10. This solves the problem that the existing injection molding molds for automotive fog light decorative parts are not easy to cool quickly and cannot remove air bubbles in the melt in time, resulting in voids inside the product.

[0029] In order to expel air bubbles through vibration, such as Figure 1 and 2 As shown, the vibration exhaust mechanism includes a motor 14, a support rod 15, and a cam 16. The motor 14 is fixedly connected to one end of the cavity of the base 1, and the support rod 15 is rotatably connected between the two ends of the base 1. The cam 16 is fixedly connected to the wall of the support rod 15. One end of the motor 14 is fixedly connected to the support rod 15. The motor 14 drives the support rod 15, causing the cam 16 to reciprocate and push the mold assembly up and down continuously during rotation, generating vibration. Through continuous vibration, air bubbles in the solution are discharged.

[0030] In order to perform the demolding process, such as Figure 2 and 3As shown, the demolding mechanism includes a demolding top opening 17, ejector pins 18, electric push rods 19, and a connecting plate 20. Multiple demolding top openings 17 are provided in the mold groove of the lower mold 9. Each demolding top opening 17 is slidably connected to an ejector pin 18. An electric push rod 19 is fixedly connected inside the cavity of the drive chamber 8. One end of the electric push rod 19 is fixedly connected to the connecting plate 20. The other end of each ejector pin 18 passes through the top of the drive chamber 8 and is fixedly connected to the top of the connecting plate 20. By using the connecting plate 20 provided at one end of the electric push rod 19, the multiple ejector pins 18 are pushed upwards, causing them to move upwards in the demolding top openings 17, thus ejecting the cooled mold out of the mold groove.

[0031] To achieve a cooling cycle, such as Figure 1 and 2 As shown, both the cooling water inlet assembly 11 and the cooling water outlet assembly 12 include a connecting chamber 21, a water pump 22, and a circulation hose 23. The water pump 22 is fixedly connected inside the cavity of the connecting chamber 21, and two circulation hoses 23 are fixedly connected to the output end of the water pump 22. The other ends of the two circulation hoses 23 are fixedly connected to the upper mold 7 and the lower mold 9, respectively. The cooling water inlet assembly 11 and the cooling water outlet assembly 12, which are composed of the connecting chamber 21, the water pump 22, and the circulation hoses 23, supply cooling water to the upper mold 7 and the lower mold 9 after the cooling water inlet assembly 11 is connected to a water source, and the cooling water outlet assembly 12 draws water from the cavities of the upper mold 7 and the lower mold 9 through the water pump 22 and the circulation hoses 23, thereby realizing cooling circulation.

[0032] To achieve sealing and enhance heat dissipation, such as Figure 2-4 As shown, the bottom of the upper mold 7 is provided with a sealing groove 24, and a cooling hollow insert 25 is fixedly connected to the bottom of the upper mold 7. The top of the lower mold 9 is engaged with the sealing groove 24, and a connecting port 26 is provided on the top of the lower mold 9. The cooling hollow insert 25 is inserted into the connecting port 26. The cooling hollow insert 25 and the gas cooling chamber 5 are provided with corresponding circulation ports 27. By using the sealing groove 24, the upper mold 7 and the lower mold 9 are sealed when they are joined to prevent solution leakage. By using the cooling hollow insert 25, the gas cooling chamber 5 is connected to cooling gas pipes at both ends during use. Gas enters and exits the cooling hollow insert 25 through the circulation port 27, replacing the heat in the center of the upper mold 7. At the same time, the heat in the center of the lower mold 9 is replaced by the heat in the connecting port 26, thereby enhancing the heat dissipation function.

[0033] To cushion and protect the mold components from vibration, such as Figure 1 and 2 As shown, rubber buffer pads 28 are fixedly connected to both ends of the top of the base 1. The rubber buffer pads 28 are used to buffer and protect the mold assembly under vibration.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
