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 assembly includes a services block and a cavity plate defining at least a portion of a molding cavity. A quick connection mechanism can connect and disconnect the plate and the services block. The cavity plate may include a base block and a mold cavity block. A mold assembly may include two opposed combinations of such a service block and a cavity plate each mounted to an opposed platen. The base block may include a quick connection device operable connect with and disconnect from a quick connection device on the services block. A services channel in the cavity plate may connect with and disconnect from a service channel in the services block with a quick connection mechanism. A molding system may include a plurality of such cavity plates, each operable to connect with and disconnect from the same services block.

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.

A container manufacturing device for performing manufacture of a pre-form and a container in a single station via one stop is provided. 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 the pre-form 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.

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.

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.
