Abstract

Oppfinnelsen angår en anordning ved en form for ved støping av gjenstander av fortrinnsvis porøse eller cellestrukturerte materialer, å utta hull eller utsparinger i gjenstanden, idet formen omfatter innbyrdes bevegelig anordnete form-halvdeler (14, 16). Den ene form-halvdelen (16) bærer minst ett toarmet hevstangelement (20) hvis ene hevarm (24) oppviser et for forming av hullet beregnet formlegeme (28) og hvis andre hevarm (32) er innrettet til i form-halv- delenes sammenførte tilstand å ligge an mot et an- slag (40) på den andre form-halvdel (14) for å holde hevarmen (24) som oppviser formlegemet (28) i en formestilling.The invention relates to a device in a mold for removing holes or recesses in the article by molding articles of preferably porous or cellular structured materials, the mold comprising mutually arranged mold halves (14, 16). One mold half (16) carries at least one two-arm lever member (20) whose one lever (24) has a mold body (28) for forming the hole and the other lever (32) is arranged in the mold half assembled being able to abut an abutment (40) on the second mold half (14) to hold the lever (24) exhibiting the mold body (28) in a molding position.
