An injection molding system includes an injection station, a molding device, and a plunger. The injection station includes a platform including an opening and an injector over the platform. The molding device is disposed between the platform and the injector and over the opening, wherein the molding device includes a mold cavity and a clamping unit for clamping the molding device. The plunger under the platform, wherein the plunger includes a base and a rod extendable through the opening toward the molding device and retractable toward the base. An injection molding method includes conveying a molding device to an injection station and disposing the molding device between an injector and a platform; disposing a plunger under the platform; moving the injector towards the molding device; applying a plunging force on the molding device by extending the rod through the opening; and injecting a molding material into a mold cavity.

A carousel-like continuous molding system includes an arrangement of inclined feed channels. Each of the feed channels has a controllable valve therein positioned upstream of an inlet to an associated mold cavity. The valve is controllable so that adjustments may be made in real time to achieve or maintain delivery of molten polymeric material to the mold cavity at constant pressure.

The invention relates to a method for the production of form parts from multi-component reactive plastic material, especially from polyurethane, wherein a plurality of moulds are moved by means of mould carriages (1) at least temporarily along a closed, preferably oval, production line (2). To allow a simple and quick import and export of mould carriages in the respectively out of the production line the invention proposes that the mould carriages (1) are provided with rolls (3) and are moved on a stationary ground (4) by the same and that a plurality of supply carriages (6) are arranged along the closed production line (2) at a conveying element (5), which supply carriages (6) are moved by means of the conveying elements (5), wherein a mould carriage (1) is approached to a not occupied supply carriage (6) and is coupled with the same to introduce the mould carriage (1) into the production line (2), wherein for the movement along the production line (2) the mould carriage (1) is guided and moved by the supply carriage (6) in a coupled state between the mould carriage (1) and the supply carriage (6) and wherein the mould carriage (1) is decoupled from the supply carriage (6) and is moved away from the production line (2) for taking the mould carriage (1) out of the production line (2), wherein here the mould carriage (1) is moved with its roils (3) on the stationary ground (4). Furthermore, the invention relates to a respective device.

The molding device is disposed between the platform and the injector and over the opening, wherein the molding device includes a mold cavity and a clamping unit for clamping the molding device. The plunger under the platform, wherein the plunger includes a base and a rod extendable through the opening toward the molding device and retractable toward the base. An injection molding method includes conveying a molding device to an injection station and disposing the molding device between an injector and a platform; disposing a plunger under the platform; moving the injector towards the molding device; applying a plunging force on the molding device by extending the rod through the opening; and injecting a molding material into a mold cavity.

An injection molding system includes an injection molding apparatus that performs injection molding with a die and a conveyor apparatus on one side of the injection molding apparatus that inserts the die into the injection molding apparatus, where the conveyor apparatus includes an actuator connectable to the die. The injection molding system also includes a die detection unit that detects the conveyed die, an actuator detection unit that detects a state of the actuator, and a controller that controls the conveyor apparatus to prohibit a conveying operation of the die based on detection results by the die detection unit and the actuator detection unit.

A conveyance apparatus for conveying a mold into an injection molding machine includes a frame configured to form a supporting plane for supporting the mold, and an actuator configured to move the mold along the supporting plane between a first position inside the injection molding machine and a second position different from the first position, wherein the improvement to the conveyance apparatus includes the actuator being located below the supporting plane in a vertical direction; and a linking unit configured to link the mold and the actuator, wherein the linking unit is connectable to a side surface of the mold, wherein, in a state where the mold is at the second position, at least a part of the actuator is closer to the injection molding machine than the side surface of the mold in a conveying direction where the actuator moves the mold.

A plastic molding system comprises: dispensing, pre-shaping and shaping cells and a transport subsystem. The dispensing cell has a station for dispensing a dose of plastic feedstock. The pre-shaping and shaping cells each comprise a plurality of stations for shaping the workpiece into a preform shape and into a final shape, respectively. The transport subsystem advances a workpiece along a selected one of a plurality of process paths to form a molded article. Each of the plurality of process paths is defined by a combination of stations of the dispensing cell, the pre-shaping cell and the shaping cell.
