Filed: 1989-08-25
Abstract: PURPOSE:To efficiently manufacture a molten metal squeezed product with little defect by advancing a punch to the position near thick part under the unsolidified condition of the molten metal in a metallic mold and further advancing the punch under high pressure after solidifying the molten metal at the gate of the metallic mold. CONSTITUTION:After clamping a fixed mold 8 and movable mold (not shown in the figure) of the metallic mold M, the molten metal is filled up in a cavity 21 through a sprue 22. Successively, by advancing the punch 16, the molten metal is pressurized and cast. In the above molten metal squeezing method, the punch 16 is advanced to the position near the thick part T in the product under the unsolidified condition of the molten metal M. Then, the working pressure of the punch 16 is set to a lower force than the clamping force for the metallic mold M and gap in the molten metal at the thick part T is easily eliminated. Successively, after solidifying the molten metal at the gate 22a in the metallic mold M, the punch 16 is further advanced with great force. Then, the working pressure of punch 16 is set to a higher force than the mold clamping force for metallic mold M. By this method, the molten metal squeezing is executed with suitable pressure without being limited with the mold clamping force to obtain the casting product having little defect.
