Apparatus for producing flat plastic moldings, for example identity cards

An apparatus for producing flat plastic cards with an integrated circuit embedded therein, comprising:

• two mold parts that are supported for movement relative to each other and which enclose between them at least one mold space;
• a closing means connected with the mold parts to close them toward one another with a locking pressure which acts against the opening direction of the mold parts;
• said mold parts including a wedge-shaped core member having mold surfaces inclined to the direction of opening movement of the mold parts, and a die-block member shaped complementally to the core member and having surfaces respectively opposed to the mold surfaces on the core member so as to define at least two approximately two-dimensional mold spaces on respective sides of said core member when the mold is closed;
• interfitting means on the core member and die-block member which engage one another when the mold is closed, whereby the core member and die-block member brace each other when the mold is closed;
• and
• means providing for an integrated circuit module to be embedded into a flat plastic card produced by said apparatus, said providing means including a movable element provided in said core member for each of said mold spaces, each of said movable elements being shiftable substantially perpendicular to a respective side of said core member to a position within a respective one of said mold spaces so as to control the volume of the mold space.
