An injection mold with a centering device includes a die-holding plate with a cavity-forming die unit, a core-holding plate with a core unit, and a stripping plate between the core-holding and die-holding plates. The centering device has a insert and a mount with a clearance, which is rotationally symmetrical about a center axis and is for receiving the insert. The insert has an opening for receiving the core unit and the insert and the clearance of the mount are insertable in a torsion-free manner in the clearance of the mount in at least three positions rotatable about a center axis of the insert, and the center axis of the clearance and the center axis of the insert overlie one another. A center axis of the opening of the insert is arranged eccentrically in relation to the center axis of the insert by an offset. The centering unit is arranged in the stripping plate.

An assembly is formed by an insert and an overmolding device including a lower mold part and an upper mold part that are movable with respect to one another between an open position, which is suitable for the arrangement and removal of a glass pane and of the insert to be overmolded, and a closed position, in which the two mold parts delimit at least one cavity for injection of the overmolding material, wherein the lower part includes a receiving housing that is designed, on account of having a complementary shape to a referencing member of the insert, to form a stop for the member in a direction of insertion of the insert, and to immobilize the member along a vertical axis.

An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting 5 plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

A mold apparatus for producing a molded article by injection molding includes (a) a base plate for mounting to a platen of an injection molding machine; and (b) a core plate movably coupled to the base plate and axially translatable relative to the base plate between a plate advanced position and a plate retracted position. A method of resetting the core plate includes energizing a mechanical actuator in a retraction direction to exert a retraction force against the core plate and axially translate the core plate relative to a base plate from the plate advanced (molded part ejection) position to a plate retracted (mold injection) position; and then, prior to applying clamping tonnage, relieving the retraction force to axially unload the mechanical actuator, wherein the actuator is isolated from axial force exerted across the mold during application of the clamping tonnage.
