Title:
METHOD AND APPARATUS FOR SUPPLYING MOLTEN RESIN MASS
Document Type and Number:
WIPO Patent Application WO/2007/094518
Kind Code:
A1
Abstract:
This invention provides a method and apparatus for supplying a molten resin mass,
in which a part of a molten resin extruded from a die head in an extruder can be cut
into a molten resin mass which can be fallen without delay from a cylindrical transfer
guide, for transferring the mass to a female mold for compression molding, into
the female mold for compression molding. The apparatus for supplying a molten
resin mass comprises a cylindrical transfer guide for transferring a molten
resin mass, obtained by cutting a predetermined amount of a molten resin extruded
from a die head in an extruder, to a female mold for compression molding. Vibration
generation means for vibrating the transfer guide is provided. In the method
for supplying a molten resin mass, the pressure within the cylindrical transfer
guide is set so as to be higher than the pressure within the female mold for compression
molding.
