Abstract

PURPOSE:To readily mold the vacuum mold without any large-size flasks by placing a film along the inside wall surface consisting of a pattern plate and a flask, packing filler in the spacing, vaccum-solidifying this then performing parting and rapping. CONSTITUTION:A flask 1 is placed on a pattern plate 1 comprising communicating a vacuum chamber 3 and the surface including a pattern 4 through fine suction holes 5, thence the inside of the vacuum chamber is evacuated to let a flexible film 8 contact closely along the entire surface of the inside wall surface of the flask 7. A suction pipe 10 is detained in the recess 6 of the flask 7 and filler 11 is packed in the space formed by the film 8. A film 12 is then put thereon. The suction pipe 10 is communicated with a vacuum source to let the filler 11 solidify under reduced pressure. Thence, the vacuum in the vacuum chamber 3 is released and the pattern plate 1 is removed from the falsk 7 side and is thereby parted, following to which the flask 7 is pulled downward from the vacuum mold 15 with the flask 7 to perform rapping and hold the suction pipe 10 in the inside, whereby the vacuum-solidified flaskless vacuum mold is obtained.
