Title
(EN) A MACHINE FOR MOULDING COMPOSITE MATTER AND A METHOD OF PRODUCING CERAMICS-BASED COMPOSITE
(FR) MACHINE DE MOULAGE DE MATIÈRE COMPOSITE ET PROCÉDÉ DE PRODUCTION DE COMPOSITE À BASE DE CÉRAMIQUE
Abstract
(EN)
The inventions solve the problem of designing a machine for producing moulded composite parts that are homogeneously structured and the problem of finding a method for producing composite for implants. The essence of the design of the machine consists in that it has a portioning assembly, whereby above a mould form unit (14) there is a guiding unit (11) located opposite a dosing unit (6) and above the aforementioned guiding unit (11) there is a pressing assembly (20) slidingly mounted on a vertical frame (19) and which is equipped with at least one piston rod (25) with a rammer (27) at its end, whereby the piston rod (25) is placed within a casing (24) into which pneumatic pipes (23) are connected. The essence of the method consists in that a preliminary moulding is being performed by thoroughly filling a preform trough and then the matter is being pushed out of the preform trough in portions and then each portion is rammed separately until consistency containing less than 15% air is achieved.

L'invention résout le problème de la conception d'une machine de production de pièces composites moulées qui sont structurées de manière homogène et le problème de la découverte d'un procédé de production d'un composite pour implants. L'essence de la conception de la machine consiste en ce qu'elle possède un ensemble de fractionnement, grâce à laquelle au-dessus d'une unité de forme de moule (14) se trouve une unité de guidage (11) située en regard d'une unité de dosage (6) et au-dessus de l'unité de guidage (11) précitée se trouve un ensemble de pressage (20) monté coulissant sur un cadre vertical (19) et qui est équipé d'au moins une tige de piston (25) dotée d'un fouloir (27) à son extrémité, la tige de piston (25) étant placée à l'intérieur d'un boîtier (24) dans lequel sont reliées des conduites pneumatiques (23). L'essence du procédé consiste en ce qu'un moulage préliminaire est réalisé en remplissant complètement une goulotte de préforme, puis la matière est poussée à l'extérieur de la goulotte de préforme en portions, puis chaque portion est tassée séparément jusqu'à obtenir une consistance contenant moins de 15 % d'air.
