Abstract: An object of the invention is to provide an environmental test apparatus which can directly set an environmental change rate and hardly causes input errors. Change amount information associated with a total change amount and change rate information associated with a change amount per unit time can be input. A target locus of change can be set by using a change amount/change rate setting method of setting the target locus of change based on a combination of change amount information and change rate information. When setting the target locus of change by the change amount/change rate setting method, input of time information is inhibited.

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.
