影响蜡模变形的因素及控制措施

Factors Influencing Wax Pattern Deformation and its Countermeasures

阐述了蜡模组装方法、浇口的位置和数量对熔模精铸件变形的影响。通过调整蜡模组装方法,由原来的使用电烙铁组装改为使用粘接蜡组装模组和调整浇口数量,使蜡模组树后尺寸偏差减小,大大降低了后续工序的校正工作量,如果严格控制,后续工序可不做校正处理。

Effects of wax pattern assembling process,position and number of runner and riser system on deformation of easily-deformed investment castings were described. Adhesion wax was used to assemble wax pattern instead of electric iron,and runner and riser system was adjusted,which can keep assembled wax pattern in a desirable condition,greatly decreasing the modification difficulty in subsequent procedure.
