The metal mold design now adopt a form of one mole but six cayities ,this way can improve the efficiency;the mold's joint face is the ball's neutral plane,that makes the mold opened convenient;In the gating,the runner and the riser is the same ,and this design adopt scum riser,that make sure a better routing and make sure the casting's feeding;the mold use gravity to lockwasher itself;the core's material is quartz sand,and spread high tempearature resistant dope on it;In the design, same taper in the guide bush of the core box is needed to make sure open the mold easily;The insert blocks of the core box are made by numercial control processing,this way reduce the cost of production; the scale division positioner make sure the same specification has better interchangeability,also,as all the machining can be finished on the general machine tool,it make the cost low,so it can be spreaded abundant in the medium and minor enterprise;when workout the mold's processing technology,this design adopt the rough's two end plane as benchmark,the ball cavities are machined by scale division positioner;then use Autocad,Pro/e to draw planar and three dimension blueprint,use Pro/e to make three-dimensional animation.

本次设计的群铸模具采用一模六腔形式，生产效率高；模具分型面选择磨球的中性面，使得分模方便；浇注系统采用浇冒口一体形式和集渣包设计，保证了良好的加工工艺和补缩；锁模方式为重力锁模；砂芯采用石英砂，并在表层涂以耐高温涂料；芯盒导套选择一定的锥度，使取模容易；芯盒镶块运用数控加工，降低了生产成本；分度胎具保证了同种规格模具具有良好的互换性，而且因为所有加工基本都可以在普通机床上完成，生产成本低，可以为中小型企业普遍采用；在加工工艺编制过程中，采用两端面互为基准，球腔用专业夹具加工；Autocad，Pro/e分别制作了模具的二维和三维立体图，并运用Pro/e制作了三维动画演示。
