The injection mold is driven by the hydraulic cylinder into the mold cavity,using oil pressure and high pressure is called the die forging process.With the vigorous development of China's machinery,electronics,light industry,instrumentation and other industries,the demand for forging dies is increasing,the requirements for the quality of forgings are becoming higher and higher,and the delivery time is becoming shorter and shorter.Therefore,it has aroused great attention from China's relevant departments on the mold industry.The mold is used as the key scientific research project of the "purpose" and ""> "plan.It is sent to study abroad,foreign advanced forging mold technology is introduced,and the corresponding forging mold country is formulated.Standard plough.
The common advantages of low-pressure forging molds are: the type of liquid metal is relatively stable,the castings are arranged finely,the mechanical properties are good,and the castings are well formed,which is conducive to the clean and clean surface of the castings and the formation of large thin-wall castings.The recovery rate of the metal liquid is improved,and usually no riser is needed,which greatly improves the yield of the metal solution,and the yield usually reaches 90%.In addition,the working conditions are good,the equipment is simple,and it is easy to mechanize and automate,which is the outstanding strength of low-pressure forging .
