Talk about the interaction between die processing and ejection force

Data:2019-03-28 00:00 Source: Click:

Dalian die processing in the product surface uneven surface (in the ejection part), there are several cases, such as top protrusion, top piercing, top crack, top high, or in the ejection part of the product due to the ejection abnormality caused by the whiteness of the situation can be called the top of the die. The product ejection is caused by the interaction of the pull force and ejection force produced by the rough part of the product.


In industrial production, various kinds of moulds and tools are obtained by injection, blow moulding, extrusion, die casting or forging, smelting and stamping. The shape of the product is processed by changing the physical state of the forming material. Known as the "mother of industry". There are absolute relations among stamping type, stamping force and stamping accuracy.


It is difficult to determine the thickness of the die by theoretical calculation. Generally, it is obtained by experience. Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. Mould generally includes two parts: movable die and fixed die (or punch and concave die), which can be separated and combined. When the parts are separated, the blanks are injected into the die cavity to form when they are closed.


Under the action of external force, the billet becomes a tool for manufacturing with specific shape and size. Used to ensure the quality and shape of products. Precision, size, etc. The popular saying is "model". A device for defining the shape and size of a production object.
