ABSTRACT:
A device for the injection moulding of moulded bodies made from plastic is disclosed, comprising an injection moulding unit (1) and a tool (2) dedicated thereto. At least two cavities (11, 12), corresponding to the dimensions of the moulded body for production are provided on the tool (2) and the tool comprises at least three pieces (4, 5, 6), which move relative to each other and which lie adjacent to each other on separating planes (9, 10). Each separating plane (9, 10) runs through at least one cavity (11, 12). At least one channel (13) for the introduction of molten plastic is provided in the tool (2), which terminates at one end in the cavities (11, 12) and at the other end thereof at an inlet (14) on the surface of the tool (2), which is connected to the injection moulding unit (1) in the working position. In order to increase the number of moulded bodies produced per unit time, a channel (13) is provided in the tool (2), reaching from the inlet (14) to a first separating plane (9) and further leading to the second separation plane (10).
