摘要
The present invention relates to a pressing member to form a hollow inside cast during casting, its object is cast inside to prevent the shaft by applying various casting defects in the casting of the casting having a hollow portion of the symmetric by increasing the cooling efficiency of the pressing member to form a hollow portion caused by the influence of the casting during solidification, and the overall cost and process speed and high quality of the casting and to provide a pressing member that forms a hollow portion of the shaft having a symmetrical structure so as to obtain an effective cooling. ; in the cores to the invention form the axisymmetric hollow, ; wherein the pressing member has a shape corresponding to the casting to form the symmetrical axis inside the hollow casting, the inside of the pressing member and a free space forming a spiral around the axis of the pressing member, one side of the blank space of the spiral at one side of the pressing member and is associated with the cooling water inlet, the other side of the pressing member has a cooling water outlet connected to the other end of the spiral, and that is connected to the cooling water inlet and a water outlet consisting of a circulation apparatus for coolant in the circulation and distribution of the technical aspect.
