Abstract

PURPOSE: To obtain casting having few defects such as sand inclusion and warping, by communicating parallel product casting part and sprue with plural weirs, and using reduced pressure forming mold having a chiller disposed in the position corresponding to the cam end.
CONSTITUTION: Parallel product and sprue models 4, 9 are mounted on a model plate 1, and the shafts or bearing parts 5, 6 of the former and latter are communicated with plural weirs 9'. These are, when a vent hole model part 8 extending in the axial direction of the model 4 is set upward, fitted parallel as being spaced each other high above on the side of the model 4. This plate 1 is placed horizontally, and a chiller 11 is mounted on the upper part of the cam end side, and a member 12 being heated and softened while sucking through pipe 2, chamber 3 and small hole 10 is closely contacted on the surface. Then, placing a molding flask 13, a filler 14 such as sand is charged into the cavity formed on the plate 1 at high density by shaking, and the surface is coated with a flexible member 15. Reducing the pressure through pipe 17, chamber 16, perforated pipe 18, the filler 14 is solidified with external pressure through the member 15. Then, relieving of pressure reduction, the mold obtained by releasing is set up, and poured in from a sprue 25.
