Abstract

Recently the well developed squeezing casting is becoming a effective technology for the production of die module.Practical die structure and processing parameters for forging die module in squeezing casting were shown.The combination structure was adopted for both punch die and container with the cooling water channel.The auto resetting bottom ejector suitable for general hydraulic presses without the bottom ejector is installed on the die.Service life of the die can meet reguirements for productive usage.There was no cavity for inner module.Results showed that the cast defects were eliminated with full fine grains for 4Cr5W2SiV

5CrMnMo

5CrNiMo

3Cr2W8V tool steel in sgueezing casting at pressure in excess of 150 MPa.The mechanical Properties of cast steel were well in agreement with forging steel.
