A molding apparatus provided with a transfer capable of transferring a heavy-weight mold clamping device. The molding apparatus that molds a molded product, includes: a mold clamping device clamping a parison extruded from an extruder to obtain a molded body, a transfer rail to support the mold clamping device in a transferable manner, and an electric cylinder to transfer the mold clamping device along the transfer rail. The mold clamping device includes first and second platens for holding a die, and a clamping drive unit for driving the first and second platens closer to or separated from each other, the electric cylinder includes a motor having an output shaft and a feed screw mechanism that converts the rotary motion of the output shaft into a linear motion.

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.

The present invention relates to a mold for molding hollow bodies from parisons. It is the object of the invention to provide such a mold having a closing mechanism, which allows the mold to be securely held closed even under high pressure and which is in addition easy to clean. The object is achieved according to the invention by a two-part mold (1a, 1b) for molding hollow bodies, in particular containers, from parisons by way of a gaseous or liquid pressure medium introduced under pressure into the parison, in which at least a part of the mold (1a, 1b) is supported so it is rotatable about an axis of rotation (3), and therefore the two parts are transferable from an open position into a closed position, and wherein each mold part (1a, 1b) is connected to one end of a toggle lever (4a, 4b) so it is rotatable about an axis (5a, 5b) parallel to the axis of rotation (3). The two other ends of the two toggle levers are connected to one another and to an actuating mechanism (7, 8, 9) so they are rotatable about an axis (6) parallel to the axis of rotation. The mold is characterized according to the invention in that the toggle levers (4a, 4b) are located shortly before their dead center in the closed position of the mold and the actuating mechanism (7, 8, 9) exerts an elastic force on the connecting axis (6) of the toggle levers (4a, 4b) in the direction of their dead center.

A device including a drive mechanism and a mold carrier that is divided into a first part (3a) and a second part (3b) which are configured to hold a respective section (2a, 2b) of a mold for forming a hollow container from a parison through the introduction of a gaseous or liquid pressurized medium under pressure into the parison. The first part (3a) is connected to the drive mechanism (6) by a first part connection region (7a) and is rotatable by the drive mechanism about an axis of rotation (A) such that the first part and the second part are transitionable between an open position and a closed position relative to each other. The first part connection region passes through a protective wall (8) that is arranged between and separates the mold carrier from the drive mechanism and thereby protects the drive mechanism against contamination on the mold carrier side.

A melt dispenser for plastic molding comprises a barrel unit removably mountable to a drive unit. A feed screw is received within a barrel of the barrel unit and is rotated by the drive unit to dispense molten molding material through an outlet of the barrel. A coupling mechanism can be engaged to hold the barrel unit against the drive unit and on to connect the screw to the drive. The coupling mechanism is operable by an actuator.

A container manufacturing device is provided. In detail, the container manufacturing device for performing manufacture of a container pre-form and container molding in a single station via one stop. The container manufacturing device includes a pre-form molding module configured to form a shape of a pre-form of a container using a resin material, an injection module connected to the pre-form molding module and configured to supply the resin material to the pre-form molding module, a container molding module configured to inject air to a pre-form completed by the pre-form molding module to expand the pre-form and to form the shape of the container, and including a container mold, and a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate.

Machine for forming containers made of thermoplastic material by blow-molding preforms obtained by means of injection/molding within the machine, for which at least one longitudinal direction for feeding of the preforms between the stations thereof is defined, said machine including: an injection unit provided with a longitudinal injector; a station for molding the preforms, comprising a mold with a predefined number of cavities for injection/molding of preforms; a station for blowing the preforms, comprising a blowing assembly for forming finished containers; said blowing assembly comprising a smaller number of blowing cavities than the number of injection/molding cavities in the mold and being displaceable in both senses of the longitudinal direction on fixed longitudinal guides.

An apparatus (100) for the continuous cycle production of containers from plastic material comprises a metering unit (1) configured to receive from an extruder a flow of molten plastic and to produce a plurality of doses simultaneously from the flow of molten plastic; a forming station (2) includes a plurality of female compression elements (3) for simultaneously receiving the plurality of doses from the plurality of outlets of the metering unit; a plurality of male elements (4) acts in conjunction with the female compression elements (3) to make a plurality of parisons simultaneously by compression moulding; a blow moulding station (5) is configured to receive the parisons of the plurality of parisons and to blow mould the plurality of parisons to form a corresponding plurality of containers.
