A method of feeding a molten resin mass, which is capable of causing a molten resin mass to fall down into a female mold for compression molding without delay in the timing from a cylindrical transfer guide that cuts a portion of a molten resin extruded from a die head of an extruder and transfers it to a female mold for compression forming, and an apparatus therefor. The apparatus for feeding the molten resin mass has a cylindrical transfer guide which transfers a molten resin mass obtained by cutting a predetermined amount of a molten resin extruded from a die head of an extruder to a female mold for compression molding, wherein the transfer guide is provided with vibration-generating means for imparting vibration to the transfer guide. In the method of feeding the molten resin mass, the pressure in the cylindrical transfer guide is set to be higher than the pressure in the female mold for compression molding.
An apparatus for feeding a molten resin mass, having a cylindrical transfer guide which transfers a molten resin mass obtained by cutting a predetermined amount of a molten resin extruded from a die head of an extruder to a metal mold for compression molding, wherein the transfer guide is provided with vibration-generating means for imparting vibration to the transfer guide.
A compression-molding method by overlapping a cylindrical transfer guide on a female mold for compression molding, and causing a molten resin mass in the transfer guide to fall down into the female mold, wherein the pressure in the cylindrical transfer guide is set to be higher than the pressure in the female mold for compression molding.
A compression-molding apparatus comprising a female mold for compression-molding a molten resin mass, a cylindrical transfer guide which can be overlapped on the female mold and is capable of containing the molten resin mass extruded from a die head of an extruder, and a pressure differential-imparting unit which sets the pressure in a container chamber of the transfer guide to be higher than the pressure in the female mold for compression-molding.
A method of feeding a molten resin mass by overlapping a cylindrical transfer guide on a female mold for compression molding, and causing a molten resin mass in the transfer guide to fall down into the female mold, wherein the molten resin mass is caused to fall down into the female mold for forming by blowing a high-pressure air into a container chamber of the transfer guide from a nozzle head attached to an upper part of the transfer guide.
An apparatus for feeding a molten resin mass comprising a female mold for compression-molding a molten resin mass, a cylindrical transfer guide which can be overlapped on the female mold and is capable of containing the molten resin mass obtained by cutting a predetermined amount of a molten resin extruded from a die head of an extruder, and a nozzle head attached to the vertex of the transfer guide and having a nozzle formed 5 therein, wherein the nozzle has an injection port opened in an upper region of the container chamber of the transfer guide.
