An apparatus for assisting in the removal of an ejection-molded article from the core of a mold is disclosed in combination with a molding machine in which the mold core is fixed to a moving platen and an ejector mechanism is supplied which mechanically removes the article from the core. The assisting apparatus includes a conduit leading to a surface of the mold core which defines the bottom of the article formed. A piston and cylinder is connected to the conduit, the interior of the cylinder being dimensioned to be approximately equal to the interior volume of the article formed. The cylinder is fixed with respect to the platen, while the piston is fixed with respect to the ejector apparatus. As the ejector moves with respect to the mold core so as to mechanically strip the molded article from the core, the piston moves within the cylinder which is filled with air at approximately 1 atmosphere, thereby causing the air within the cylinder to be introduced into the conduit and thus into the void developing between the bottom of the formed article and the mold core, thereby preventing deformation of the formed article. |
