Abstract
A device for removing molded articles and cured sprues from the cavity and cover plates, respectively, of a multi-plate multi-cavity injection mold, includes a molded article ejection unit and a sprue extraction unit which, when the molding machine is opened, are juxtaposed, respectively, to a space between the mold cover and cavity plates and to a space between the mold cover plate and the face plate of the injection unit of the machine. A common carrier unit is provided for shifting the article ejection and sprue extraction units jointly into and out of the said spaces. In a preferred construction, the article ejection unit includes a plurality of ejector pins for the mold cavities, and means responsive to the arrival of the ejection unit at the end of its in-stroke for causing the ejector pins to penetrate the cavities from one face of the cavity plate. A trough-shaped guide unit movable with the ejection unit but into juxtaposition to the other face of the cavity plate is also provided, to define a guide chute for the ejected articles. The sprue extraction unit includes a rotatably driven roller which during its in-stroke is in rubbing or wiping contact with the outside face of the mold cover plate for pulling the cured sprues therefrom. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention.
