Title (EN) MOLD LAMINATE ASSEMBLY FOR AN INJECTION MOLD MACHINE
(FR) ENSEMBLE DE LAMELLES DE MOULAGE POUR MACHINE DE MOULAGE PAR INJECTION
Abstract:
(EN) A reconfigurable injection mold machine (10) is disclosed having a fixed mold body (60, 60') and two movable mold bodies (62, 62' and 64, 64') that can be automatically repositioned with respect to each other to make different mold cavities for molding different parts. The three mold bodies (60, 60', 62, 62' and 64, 64') each include a laminate subassembly (140, 140', 142, 142', 144, 144') composed of a plurality of laminates (162, 162', 164, 164', 204, 204', 234, 234') and a mounting frame (146, 146', 192, 192', 218, 218') arranged to hold and position the laminates during assembly to the mold. The mounting frame permits preassembly of the laminates on the workbench into a subassembly (140, 140', 142, 142', 144, 144') that is then easily inserted into an opening in the mold (60, 60', 62, 62' and 64, 64') and secured in place. Additionally, the mounting frame (146, 146', 192, 192', 218, 218') secures the laminates (162, 162', 164, 164', 204, 204', 234, 234') in their respective positions during reconfiguration of the movable mold bodies (62, 62' and 64, 64') and serves to maintain the laminate assemblies in proper alignment when in a non-active or idle position.
(FR) Machine de moulage par injection pouvant être configurée (10), comportant un boîtier de moulage fixe (60, 60') et deux boîtiers de moulage mobiles (62, 62' et 64, 64') pouvant être repositionnés automatiquement les uns par rapport aux autres pour reconstituer diverses cavités de moulage pour des pièces de moulage diverses. Les trois boîtiers de moulage (60, 60', 62, 62' et 64, 64') abritent chacun un sous-ensemble de lamelles (140, 140', 142, 142', 144, 144') constitué d'une série de lamelles (162, 162', 164, 164', 204, 204', 234, 234') et un châssis de montage (146, 146', 192, 192', 218, 218') conçu pour maintenir et positionner les lamelles au cours de leur assemblage dans le moule. Le châssis de montage permet un pré-assemblage des lamelles sur la table d'ouvrage en un sous-ensemble (140, 140', 142, 142', 144, 144') qui peut être aisément introduit dans une ouverture du moule (60, 60', 62, 62' et 64, 64') et fixé en place. En outre, ce châssis de montage (146, 146', 192, 192', 218, 218') immobilise les lamelles (162, 162', 164, 164', 204, 204', 234, 234') à leur emplacement respectif lors de la reconfiguration des boîtiers mobiles de moulage (62, 62', 64, 64') et permet de maintenir les ensembles de lamelles en alignement lorsqu'ils sont inutilisés.
