Abstract
A hollow body molding device forming a hollow molded body in a main cavity of a mold having in its one end a pressure port including a floating core by injecting molten resin through an injection gate into the main cavity having an outlet, and then pressure-injecting pressurized fluid through the pressure port into the main cavity to move the core toward the outlet through the resin injected into the main cavity to extrude the resin through the outlet and discharge it into a waste cavity, the device having: a floating core accommodating portion located between the outlet and a communication passage leading to the waste cavity and adjoins the main cavity and accommodates the core moved to the outlet by the fluid, in the device, a floating core accommodating portion inside diameter is smaller than a main cavity outlet diameter and is larger than a floating core outside diameter.
