[0002] At present, molds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. The development of my country's mold industry has given strong support to the manufacturing industry, and at the same time, the development of the manufacturing industry has also promoted the development of the mold industry.

[0003] The current stretching die used for automotive sunroof fabric roller blind boxes is a mold specifically designed for processing automotive sunroof roller blind box components. However, in practice, this mold lacks an efficient material ejection and positioning mechanism. The lack of a reliable ejection mechanism to ensure accurate demolding of the processed material leads to deviations in the mold's positioning and demolding process, which in turn severely impacts the uniformity and consistency of the stretching process. This situation not only severely restricts production efficiency but also can lead to a series of product quality issues, such as scratches on the material surface, dimensional deviations, and poor product consistency, directly impacting the final product's pass rate and market competitiveness. Furthermore, improper pressure distribution between mold components during the stretching process can lead to stress concentration, compromising the final product quality and causing problems such as cracks and deformation.

[0004] Therefore, a stretching die with a pushing structure is needed to solve the above problems. Utility Model Content
