论述了某小型铝合金盖压铸工艺及模具的设计过程。该模具锁模力为1150kN。针对薄小铸件结构特点,设计了弯销延时抽芯机构,动、定模均采用整体式镶块,排、溢系统均匀设在定模分型面上,采用推杆顶出机构,横浇道和内浇道均设计为扁梯形平直式。采用常规工艺参数,该模具经过试模达到一次成功。 Discusses a small aluminum die-casting process and mold design process. The mold clamping force of 1150kN. According to the structural characteristics of thin and small castings, bent core pulling delay mechanism was designed. The moving and fixed molds were all in one piece. The row and the overflow system were evenly arranged on the fixed mold parting surface. Sprue and runner are designed for the flat ladder flat type. Using conventional process parameters, the mold through a trial to achieve a success.
