Description

Technical Field

[0001] The invention relates to a vulcanization die for an aviation oil drain pipeline bracket assembly and a use method thereof, belonging to the technical field of production dies. Background Art

[0002] With the rapid development of the aviation industry, the types of aviation products are becoming increasingly diverse, and the structure of aviation rubber products is becoming increasingly complex. As one of the key components, the design and manufacturing requirements of the aviation oil drain pipe bracket assembly are extremely strict. By vulcanizing rubber on the metal frame, this assembly achieves effective support and cushioning of the pipeline, thereby improving the safety and reliability of the aircraft.

[0003] However, there are a series of technical difficulties in the manufacturing process of aviation oil drain line bracket assemblies. Specifically, the rubber part is usually designed with an irregular shape and contains two irregular concave holes. Although this design can meet specific performance requirements, it poses a great challenge to the positioning of the vulcanization mold. Due to the irregularity of the rubber shape, it is difficult to accurately align the mold during the pressing process, resulting in low production efficiency and difficulty in ensuring product quality.

[0004] In addition, the demoulding process is also a major technical difficulty. Due to the close combination between the rubber and the metal frame and the irregular shape of the rubber, the product is easily torn or damaged during demoulding, further reducing the product qualification rate, increasing production costs, and seriously affecting the product delivery cycle and customer satisfaction.

[0005] On the other hand, the metal frame of the aviation oil drain line bracket assembly is usually designed with thin walls to reduce weight and improve performance. However, this thin-wall design easily leads to deformation of the frame during the pressing process. The deformation of the frame not only affects the appearance quality of the product, but also reduces its support and cushioning performance, thereby endangering the safety of the aircraft.

[0006] In summary, a new type of aviation oil drain pipe bracket assembly vulcanization mold is urgently needed to overcome the above-mentioned difficulties. Summary of the invention
