Wave generator mixing head with directive mixing chamber

Abstract

The invention relates to a system (1) including a mixing head (2) for mixing at least two components (K1, K2) for producing a plastic part, the mixing head is provided with at least one input (3) for inserting each at least one component (K1, K2), at least one output (4) connected with a cavity (5) of a die (6) is connectable to a mixing chamber (7),a mixing chamber (7) communicated with the input (3) and connected with at least one output (4), and a discharging device (8) for discharging the mixture (M) consisting of the at least two components (K1, K2) from the mixing chamber (7) to the at least one output (4), and the system further includes a wave generator (9) having at least one wave emitter (10) which is configured to emitting wave (W) to the mixing chamber (7).

Description

technical field [0001] The present invention concerns the problem of mixing two components for the manufacture of a plastic. Background technique [0002] This problem is known, for example, from the mass production of automobiles. In this case, an economically meaningful further reduction of the cycle time increasingly hits the technical limit, because the rapid release-to-manufacturing system (RTM-system) has a very narrow temperature- Process windows and due to short production standstills with highly reactive systems or components in the delivery hose and in the mixing head can already cause premature reactions of the material, resulting in production interruptions and costly cleaning Work. Reactive systems are typically also processed starting from liquid, tempered individual components, which is accompanied by high thermal stress and slow material decomposition in the storage tank due to the long residence time. [0003] Conversely, if at least two components are no...

Problems solved by technology

For reactive systems, while yielding the advantage of accelerated reaction times, there is a disadvantage: localized energy input leads to different morphological states and reaction transformations in the final product

[0012] EP 0 904 923 A1 and WO 2004 / 24415 A1 are publications which, although they each show a wave transmitter, do not involve mixing of plastic components and indeed do not involve mixing of reactive original components at all

The mixing chamber is therefore also not described
