Embodiment Construction

[0055] figure 1 Shown is a forming carousel 1 which is part of an extrusion molding machine for extrusion molding objects starting from a dose of polymeric material. The molding machine comprises an extruder for extruding a continuous extrudate of polymeric material and a cutting device for separating doses of polymeric material from the continuous extrudate. The cutting device is configured to separate the doses by cutting the continuous extrudate of polymeric material at predetermined distances. The molding machine may also comprise transport means, for example similar to a transport carousel, for transporting doses towards one or more molds 2 in which an object of the desired shape will be obtained with each dose. In the example shown, a plurality of molds 2 are provided, the molds 2 being supported by the forming carousel 1 , in particular by the peripheral area of ​​the forming carousel 1 . The forming carousel 1 is rotatable about an axis R, which in the example shown ...

Abstract

A distributor device (14) is arranged for controlling a plurality of actuators (5), each of which is intended to open or close a corresponding mould (2). The distributor device (14) comprises a rotarypart (15) rotatable about an axis (R) and connectable to the actuators (5) of said plurality, and a stator 5 part (16) in fluid communication with the rotary part (15). The stator part (16) is provided with: - low pressure distributor means (20), configured to selectively send an actuating fluid at a first pressure to the rotary part (15), so that one actuator (5) of said plurality moves a firstcomponent (3) and a second 10 component (4) of the corresponding mould (2) closer to each other from a distanced position (P1) to an intermediate position; - high pressure distributor means (27), configured to selectively send an actuating fluid at a second pressure higher than the first pressure to the rotary part (15), so that said actuator (5) moves the first 15 component (3) and the second component (4) of the corresponding mould (2) closer to each other from the intermediate position to a forming position (P2); - maintaining distributor means (30), configured to selectively send an actuating fluid to the rotary part (15), so that said actuator (5) 20 maintains the first component (3) and the second component (4) in the forming position (P2).

Description

technical field [0001] The present invention relates to a dispenser device for distributing an actuating fluid into a plurality of molds of a molding machine. The molding machine in which the dispenser device is intended to be incorporated may be, for example, an extrusion molding machine for producing objects made of polymeric material by compression moulding. In this case, the dispenser device is connected to a plurality of moulds, each of which is intended to contain a dose of polymeric material and to compress this dose so as to obtain the desired object. Background technique [0002] Extrusion molding machines are known comprising a carousel rotatable about a vertical axis. The carousel supports in its peripheral region a plurality of molds, each of the plurality of molds being adapted to form objects made of polymeric material. [0003] Each mold comprises a female element provided with a cavity into which a dose of polymeric material in molten state is deposited. E...
