Analyse & Practice Of The Casting Mould

The mold is the basic process equipment. The technology of the casting mold has been the sign of the level of manufacturing of one country. It can serve all kinds of departments of the society, and it adopts new technology. The design and machining of the difficult casting mold will develop with the other related fields. And the new technology and new way come out again and again. With that happens, the design and machining of casting mold will have more and more technology and it has been the joined point of the advance technology and process of mechanics.This text has taken the DA465 for example, which is metal casting mold of aluminum alloy cylinder head and hot core box mold. And it has analyzed the design of the casting mold in theory, and in the same time it has mentioned the way of controlling and preventing of the shortage of casting, and it has systematically concluded the basic process of designing such cylinder head casting mold.First through comparing all kinds of factors, confirm the way of pouring and adopt the meld pattern mold .Then analyze the way and principle of the main construction design of metal pattern mold and confirm the position of pouring .At the same time discuss the way and principle of designing pouring and output gas system. Then analyze supporting way of the core head and the core base and choosing the reasonable supporting clearance. Calculate hot balance of the metal pattern mold. Analyze the reason of failure of the metal pattern and the way of prolonging its use life. Conclude how to choose the metal material.At last analyze the design of hot core mold and the its work process .At the same time analyze how to confirm the position of blow hole and how to output the...
