Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a sheet metal stamping die that is easy to demold. Background Technology

[0002] As people's quality of life improves, more and more people are traveling by car, and the demand for cars is growing. In car manufacturing, a large amount of sheet metal is needed. Sheet metal refers to metal products made from thin sheet metal into various shapes. Sheet metal needs to be stamped before it can be used in cars. In the process of stamping sheet metal, sheet metal stamping dies are generally used.

[0003] For example, Chinese patent application No. 202322335772.8 discloses an automotive sheet metal stamping die, including a lower template. A base plate is fixedly connected to the lower surface of the lower template, and an upper template is provided above the lower template. A stamping rod is fixedly connected to the upper surface of the upper template. This technical solution uses a threaded rod to drive two opposing movable plates to move closer to each other. The movable plates drive a limiting plate and a pressing plate to limit the sheet metal, fixing it in the center of the lower template to prevent the sheet metal from shifting due to vibration. Then, a springback mechanism ensures that the sheet metal is still compressed by the pressing plate during stamping, making it less prone to shifting during pressing. This solves the problem that existing stamping mechanisms generally vibrate during operation, easily causing changes in the position of the sheet metal, and may also cause the sheet metal to shift during the pressing process, resulting in inaccurate stamping positions on the sheet metal and affecting the quality of the sheet metal.

[0004] However, the following problems still exist in this technical solution: after the stamping die has finished processing the sheet metal part, the sheet metal part is easily stuck in the die cavity after being subjected to strong pressure from the die, making it difficult to remove. Utility Model Content
