Abstract

PURPOSE: To set the chilling block to the pattern body accurately through a vacuum suction thereof by cutting off a film previously inserted into a vacuum hole formed on the body.
CONSTITUTION: A suction box surface plate 2 is communicated to the pattern body through a small hole. A vent hole 6 serving as a vacuum suction hole is securely fitted into a part of the pattern body. After the adsorption of a synthetic resin film 9 by the pattern body 1, a portion of the film 9 facing the vent hole 6 is cut off in such a manner that a chilling block can be absorbed or adsorbed. Accordingly, the chilling block can be set to the pattern and the pattern body 1 for the pressure reduction molding accurately.
