| 塑料模具的制造工艺路线 Manufacturing process of plastic mold 1.低碳钢及低碳合金钢制模具 1. mould for low carbon steel and low carbon alloy steel 例如，20，20Cr，20CrMnTi等钢的工艺路线为：下料→锻造模坯→退火→机械粗加工→冷挤压成形→再结晶退火→机械精加工→渗碳→淬火、回火→研磨抛光→装配。 For example, the process of 20, 20Cr, 20CrMnTi steel is: blanking forging die blank annealing mechanical roughing cold extrusion forming recrystallization annealing mechanical finishing carburizing quenching, tempering grinding and polishing assembly. 2.高合金渗碳钢制模具 2. high alloy carburizing steel mold 例如12CrNi3A，12CrNi4A钢的工艺路线为：下料→锻造模坯→正火并高温回火→机械粗加工→高温回火→精加工→渗碳→淬火、回火→研磨抛光→装配。 For example, the process of 12CrNi3A, 12CrNi4A steel is: blanking forging die blank normalizing and high temperature tempering mechanical roughing high temperature tempering finishing carburizing quenching, tempering grinding and polishing assembly. 3.调质钢制模具 3. quenched and tempered steel mold 例如，45，40Cr等钢的工艺路线为：下料→锻造模坯→退火→机械粗加工→调质→机械精加工→修整、抛光→装配。 For example, the process of 45,40Cr steel is: blanking forging die blank annealing mechanical roughing tempering mechanical finishing dressing, polishing assembly. |
