Method and apparatus for batched compression molding of rubber and plastic products

Provided is a method and device for batched compression molding of rubber and plastic products by means of multiple mold cavities, including alternating operation of a blank shuttle and a male mold that is in a bottle cap mold, being controlled by means of engagement of two partial gear sets. Mold opening motion, isostatic pressing energy storage, and spring energy storage are implemented by means of the engagement characteristic of the partial gear sets, and mold closing and compression molding are implemented by means of the non-engagement characteristic, isostatic pressing energy storage, and pressurization of the partial gear sets. The method and device effectively resolve the general problem of low production efficiency and poor precision and stability of existing compression molding cap manufacturing equipment.

SECONDARY BATTERY POUCH PRESS MOLD

Press mold for secondary battery a press upper mold; at least two overforming punches arranged to be raised and lowered in the press upper mold; a plurality of forming punches arranged in the press upper mold to be raised and lowered between the overforming punches and the press upper mold; a press lower mold provided with a bridge forming protrusion protruding from an upper surface thereof; the bridge forming protrusion configured to form a bridge to be protruded from the pouch sheet, and a pouch sheet holder disposed to be raised and lowered on the press lower mold and fixing the pouch sheet together with the press upper mold, wherein the plurality of forming punches include a center punch in which a bridge forming groove into which a bridge is inserted is recessed on a lower surface.

Tooling device for making a plastic film component

A tooling device for making a plastic film component. The tooling device includes a molding tool having a molding part, a receptacle, an opening and closing device, and at least one covering device having a covering surface and guide arrangement. The molding part and the receptacle are movable relative to each other between a closed and an open position. Relative movement between the molding part and the receptacle to the closed position is transmitted to the covering device to move it from an exposed position, in which the covering surface is spaced from an inner surface of the molding part, to a covered position, in which the covering surface covers a covered section of molding part's inner surface.
