Forming tool, in particular for the plastic injection moulding, by means of internal gas pressure and method for the production of plastic - injection moulded articles with the use of the forming tool

摘要

it is a formwerkzeug stated that, in particular, for the plastic injection molding by means of gas is designed.the formhu00e4lften limited innenhohlraum is kunststoffspritzmasse on a einlau00dfkanal filled, and a zufuhrdu00fcse is, in particular, a innendruckbeaufschlagung.furthermore, the formwerkzeug a auslau00dfkanal. in this auslau00dfkanal is an open and schlieu00dfbares valve arranged.$a in processes for the manufacture of plastic spritzguu00dfformteilen such a formwerkzeug during the spritzgieu00dfens of formteils and on the zufuhrdu00fcse fitting internal pressure for oresa cavity in the valve ugung molded in auslau00dfkanal kept closed.and after at least partial actions of formteils and when the valve is opened and closed formwerkzeug the gas from the formwerkzeug on the auslau00dfkanal opportunity.preferably the zwangsku00fchlung and enhanced cooling an exchange or connection, if necessary, on the zufuhrdu00fcse and / or an additional zufuhrdu00fcse initiated.
