Abstract
An apparatus for use in a compression molding machine to secure the position of a mass of hardenable plastic compound from which a compression molded object can be produced by upper and lower mold halves which are driven so as to be movable relative to one another. In order to prevent undesirable displacement of the plastic compound mass during closing of the mold, the apparatus includes holding pins at the lower mold half. The holding pins project beyond the mold surface of the lower mold half during charging and also during part of the compression molding process. The height of the holding pins relative to the mold surface is dimensioned to be less than the thickness of the plastic compound mass in the region of the pins.
