Injection moulding is one of the most important polymer processing operations in industry today. It is superior for mass production of complex parts to high precision at low cost. For a long time, experience, intuition and trial and error have been key factors in mould designing, mould manufacturing and molding operation.
Mould design of this design is the toy of a fork, toy is very common in our daily lives, was the children's favorite, in order to meet the needs of the market, constant innovation and reform in order to create new products and, more importantly, is to get customers 'satisfaction, my current design is due to the current market demand.
In this design, through the study of injection mold, I to have a preliminary understanding, also notes that some details in the design, understand mold structure and working principle of learning through PRO/E, you can build a simple part of parts library, and helps to improve ...
