Abstract

L'invention concerte un appareil à fabriquer des pièces moulées de matière synthétique ou de caoutchouc. Appareil caractérisé en ce qu'avant la ou les cavités de moule 16 est interposée une chambre 14 placée dans le parcours d'écoulement, proche de la cavité de moule 16, dans laquelle débouche au moins un canal d'amenée 12, faisant partie du parcours d'écoulement, et qui est élargie relativement à ce canal d'amenée 12. L'invention est plus particulièrement applicable au moulage de pièces en matière synthétique ou en caoutchouc.The invention relates to an apparatus for manufacturing molded parts of synthetic material or rubber. Apparatus characterized in that before the mold cavity (s) 16 is interposed a chamber 14 placed in the flow path, close to the mold cavity 16, into which at least one supply channel 12, forming part of the flow path, and which is widened relative to this supply channel 12. The invention is more particularly applicable to the molding of parts made of synthetic material or rubber.
