Title (EN) PROCESS DEVICE FOR COMPRESSING THE MATERIAL OF A MOULD
(FR) PROCEDE ET DISPOSITIF POUR COMPRIMER LA MATIERE D"UN MOULE
Abstract: front page image
(EN)The material of the mould (9) is poured up to a given level on a plate (1) carrying the model (2). The latter is surrounded by a form casing (3) and a filling frame (4). The setting of a lid (8) forms a hollow space (10) into which a combustible substance is ignited. The rapid combustion produces a pressure wave which compresses the material of the mould. The pressure drop of the pressurised gas thus obtained can be controlled or monitored by means of a diaphragm or a check valve so that in a brief lapse of time a homogeneous and dense mould is formed.
(FR)La matiere du moule (9) est versee jusqu"a un niveau determine sur une plaque (1) portant le modele (2). Celui-ci est entoure d"une boite de forme (3) et d"un cadre de remplissage (4). La mise en place d"un couvercle (8) forme un espace creux (10) dans lequel une substance combustible est allumee. La combustion rapide produit une onde de pression qui comprime la matiere du moule. La detente du gaz sous pression ainsi produit peut etre commandee ou reglee au moyen d"un diaphragme ou d"un clapet, de facon qu"en un bref laps de temps un moule homogene et dense soit forme.
