Mold, everyone is not strange, but the mold manufacturing and how many people understand?! The following small series on the simple to you about the mold manufacturing.
The requirements of the mould design are precise size, smooth surface, reasonable structure, high production efficiency, easy automation, easy manufacture, long life and low cost. The design is in accordance with the process requirement and is economical and reasonable.
Factors such as rigidity, orientation, unloading mechanism, positioning method, clearance size and other factors should be taken into account in the structural design and parameter selection of the die. The wearing parts on the mould should be replaced easily. For plastic and die casting, reasonable casting system, molten plastic or metal flow state and position and direction of mould cavity should be considered. In order to increase productivity and reduce runner casting loss, a multi cavity mold can be used to simultaneously accomplish multiple or identical products within a mold. In mass production, moulds with high efficiency, high precision and long service life should be adopted.
The stamping die shall adopt multi position progressive die, and the carbide insert progressive die can be adopted to improve the service life. In small batch production and trial production of new products, the simple mould has the advantages of simple structure, low cost, rapid manufacturing, such as combined die, sheet die, polyurethane rubber mold, low melting point alloy mould and zinc alloy, superplastic alloy die etc.. The mold has begun to employ computer aided design (CAD), i.e., a computer centered system for optimal design of dies. This is the development direction of die design.
The above is part of the knowledge of mold manufacturing, and would like to know more about us!
