METHOD AND DEVICES FOR PRODUCING A MOULDED PLASTIC ARTICLE |
摘要 |
The invention relates to a method for producing a moulded plastic article. Individual portions of material are removed from a flow of heat-plasticized material which flows vertically downwards from a closable dispensing apertur e of a dispenser and transferred to a mould before being pressed by closure of the mould to form a moulded article. The required portions are cut by cuttin g shears from the flow of material at a point below the dispensing aperture an d ata distance from it, the flow preferably being briefl y halted for this purpose. The invention also concerns a device for the production of a moulded plastic art icle, comprising a closable mould (8) and a material dispenser (1) for heat-plasti cized synthetic material which can be arranged above the moulding chamber (8). The dispenser has a dispensing aperture which points towards the mould (8) and c an be closed by a closure unit (6) and from which the flow (12) of plasticized mat erial emerges. According to the invention, a shearing device (9) for separating th e required portions (14) of material is situated below and at a distance from the dispensing aperture.
