A method and a molding station for producing containers filled with a liquid filling material from preforms made of a thermoplastic material. Thermally conditioned preforms are molded into containers and filled with the liquid filling material, which is supplied to the preforms under pressure as a pressure medium in a multi-part mold of a molding station. The mold is movable from a closed state into an open state in order to repeatedly supply a preform and subsequently remove a completely molded and filled container. Molding of the preform into the container is performed against the mold inner wall when the mold is in the closed state. Liquid is removed from the mold between temporally successive supplying processes starting with the conversion of the mold from the closed state into the open state. A working wheel including such molding stations, and a device including such a working wheel are also disclosed.
A method for producing containers, which are filled with a liquid filling material, from preforms made of a thermoplastic material, wherein each preform is thermally conditioned and subsequently molded into the container and filled with at least one liquid filling material which is supplied to the preform under pressure as a pressure medium during a molding and filling phase in a multi-part mold of a molding station, wherein the mold is convertible from a closed state into an open state in order to repeatedly supply a preform and subsequently remove a completely molded container, wherein the molding process into the container is performed against the mold inner wall when the mold is closed, wherein the mold is formed of a bottom mold and at least two lateral mold elements, wherein the bottom mold and the at least two lateral mold elements are movable relative to each other and in the closed state adjoin along dividing lines, wherein the bottom mold is disposed vertically below the at least two lateral mold elements, and wherein a process step of removing liquid from the mold is performed at least temporarily between temporally successive feeding processes starting with the conversion of the mold from the closed state into the open state such that the bottom mold performs a tilting movement during or after the conversion into the open state.
A molding station for producing containers, which are filled with a liquid filling material, from preforms made of a thermoplastic material, wherein the molding station comprises a molding and filling head and a multi-part mold, wherein the molding station is configured to mold and fill a thermally conditioned preform into the container with the liquid filling material which is supplied to the preform under pressure as a pressure medium during a molding and filling phase in the mold, wherein the mold is convertible from a closed state into an open state in order to repeatedly supply a preform and subsequently remove a completely molded container, wherein the molding process into the container is performed against the mold inner wall when the mold is closed, wherein the mold is formed of a bottom mold and at least two lateral mold elements, wherein the bottom mold and the at least two lateral mold elements are movable relative to each other, and in the closed state adjoin along dividing lines, wherein the bottom mold is disposed vertically below the at least two lateral mold elements, wherein the molding station further comprises a liquid draining means for removing liquid from the mold between temporally successive preform feeding processes starting with the conversion of the mold from the closed state into the open state such that the bottom mold performs a tilting movement during or after the conversion into the open state.
