Commonly used structures for precision stamping dies in […]
Commonly used structures for precision stamping dies include two-plate moulds, drawer moulds (modular moulds) and three-plate moulds (also known as eight-plate moulds).
The second plate mould is designed and fixed to the lower die plate by the stamping and stripping function structure, and the whole set of moulds is named after two relatively independent whole bodies. It is characterized by accurate precision and small stamping stroke. However, due to the high processing precision of the mould parts and high processing cost, it is largely replaced by a three-plate mould.
The drawer mould evolved from the structure of the three-plate mould, and the template was designed into a modular type, and the mould base was designed to accommodate the quick loading and unloading structure of multiple modules. It is a good solution to the problem of frequent switching of multi-number production. Under-line changeover and rapid mould change have become synonymous with its name. However, due to its relatively complicated structure, high mould manufacturing cost and high punching parameters, its application is more More stamping production for multi-stock products.
The three-plate model, as the name implies, consists of three template groups: upper mould, stripping plate and lower mould. It is suitable for stamping production with single material number or less material number. Due to simple structure, low processing cost, high precision, convenient maintenance and stability. Good characteristics, etc., adopted by most mould design and stamping manufacturers. Relatively speaking, the three-plate mould can replace the two-plate mould to some extent, and the drawer mould has more advantages in the production of multiple material numbers, so the three-plate mould and the drawer mould become the mainstream of the high-speed precision stamping industry at this stage.
