Description

Technical Field

[0001] This utility model relates to the technical field of automotive rear wing injection molding devices, specifically to a paint-free automotive rear wing process mold. Background Technology

[0002] As an important component of a car's exterior, the rear spoiler is generally an injection-molded product. In the traditional production process, after the rear spoiler is injection molded, it usually needs to be painted before leaving the factory to meet requirements for appearance, color, and gloss. However, traditional injection molds have many drawbacks in the production of car spoilers. First, the painting process generates a large amount of volatile organic compounds (VOCs), causing environmental pollution. Second, the adhesion between the paint and the spoiler substrate is poor. During daily use, the spoiler is affected by various external factors such as wind, sun, and rain, and the paint is prone to peeling over time. Furthermore, painting multi-colored spoilers requires multiple processes such as masking, spraying, and drying, greatly increasing the complexity of the production process. Utility Model Content

[0003] (I) Technical Issues

[0004] This utility model provides a paint-free process mold for automobile rear wings, which solves the problems of environmental pollution from painting, easy paint peeling, and complex multi-color painting processes in traditional mold production, and realizes paint-free production.

[0005] (II) Technical Content

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a paint-free process mold for an automobile rear wing, comprising an upper mold body, a lower mold groove, a substrate injection molding system, a ribbon injection molding system, and a cooling system. After the upper mold body and the lower mold groove are closed, a main body cavity for the rear wing and a ribbon insert cavity are formed. The ribbon insert cavity is located on the bottom surface inside the lower mold groove and distributed on the surface of the main body cavity. The substrate injection molding system penetrates the upper mold body and connects to the main body cavity of the rear wing. The ribbon injection molding system is independently set inside the lower mold groove and connects to the ribbon insert cavity. The cooling system includes cooling water channels embedded inside the lower mold groove. The substrate injection molding system includes a main substrate runner, a substrate distribution channel, and a substrate inlet. The ribbon injection molding system includes a main ribbon runner, a ribbon distribution channel, and a ribbon micro-dot inlet.

[0007] Furthermore, the depth of the color strip groove cavity is 0.5-2mm, the width is 3-15mm, and its outline completely matches the color strip area of ​​the tail wing design.

[0008] Furthermore, the injection timing of the substrate injection molding system and the ribbon injection molding system is controlled by independent solenoid valves, with the ribbon melt injected first for 0.5-2 seconds and then the substrate melt injected.

[0009] Furthermore, it also includes a frame, with the lower mold slot fixedly located at the bottom of the frame, and the upper mold body slidably located inside the frame via a linear bearing. An electric push rod for driving the upper mold body to rise and fall is fixedly provided at the upper end of the frame.

[0010] (III) Technical Effects

[0011] Compared with existing technologies, the advantages of this invention are as follows: By setting up independent substrate injection molding systems and ribbon injection molding systems, the ribbon melt and substrate melt are injected into different cavities in a specific sequence, avoiding the traditional painting process and eliminating VOC pollution at its source, thus meeting the requirements of green and environmentally friendly production. The ribbon groove cavity perfectly matches the ribbon area of ​​the tail wing design, and the ribbon melt is injected before the substrate melt, ensuring a tight bond between the ribbon and the substrate. Compared with traditional paint, its adhesion is stronger, effectively avoiding peeling problems caused by long-term use, and improving the product's appearance quality and service life. In addition, by eliminating multiple painting processes such as masking, spraying, and drying, the production process is simplified, the production cycle is shortened, production costs are reduced, production efficiency is significantly improved, and the product's market competitiveness is enhanced.

[0023] Combined with appendix Figure 1 To be continued Figure 7 A paint-free process mold for an automotive rear spoiler includes an upper mold body 1, a lower mold groove 2, a substrate injection molding system 3, a ribbon injection molding system 4, and a cooling system 5. When the upper mold body 1 and the lower mold groove 2 are closed, they form a rear spoiler main body cavity 21 and a ribbon insert cavity 22. The ribbon insert cavity 22 is located on the bottom surface inside the lower mold groove 2 and distributed on the surface of the main body cavity 21. The substrate injection molding system 3 penetrates the upper mold body 1 and connects to the rear spoiler main body cavity 21.

At this time, the upper mold body 1 and the lower mold groove 2 form the tail wing main body cavity 21 and the ribbon insert cavity 22. Subsequently, the independent solenoid valve first controls the ribbon injection system 4 to work. The ribbon melt flows through the ribbon main runner 41 and the ribbon branch runner 42, and is injected into the ribbon insert cavity 22 through the ribbon micro-point injection port 43. The filling depth is 0.5-2mm, the width is 3-15mm, and the ribbon insert cavity 22 completely matches the tail wing design ribbon area. After 0.5-2 seconds, the substrate injection system 3 is started.
