Document Type and Number:
WIPO Patent Application WO/2007/034815
Kind Code:
A1
Abstract:
This invention provides a mold that can enhance the transferability of the surface of
a molded product and can allow the molded product to be taken out immediately after
the solidification, whereby molding cycle can be accelerated. In the mold, both
a stationary side mold and a movable side mold are mounted within masters (4, 5),
and a cavity face is formed on a release side. A plurality of heating medium passages
(48a, 58a) are bored at a position distant by a given distance from the cavity face.
The mold comprises a 15 to 30 mm-thick rectangular bushes (48, 58) formed of a metal
having a coefficient of thermal conductivity of 20 to 40 W/(m K), heat insulating
plates (38, 39) having a coefficient of thermal conductivity of not more than
5 W/(m K) and held between the masters (4, 5) and the bushes (48, 58), a pair of heating
medium manifolds (49) mounted on both ends of the anticavity face of the bushes
(48, 58) so as to be led to the heating medium passages (48a, 58a) of the bushes (48,
58), and a plurality of pressing members (42, 43) for pressing four edges of the
bushes (48, 58) to fix the bushes (48, 58) to the masters (4, 5).
