MAINTENANCE OF MOULDS FOR MAKING REINFORCED RUBBER ARTICLES Russian patent published in 2015 - IPC B29C45/14 B29C35/02 B29C70/48 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly, to production of rubber articles by curing in moulds and can be used for production of reinforced dampers and elastic support hinges (ESH). Maintenance of injection mould including the case with forming block secured at male die interacting with female die consists in fitting the case with forming block in injection mod and withdrawal of it therefrom. Stepped-section ring is made, its smaller OD complying with female die ID while ID leading edge is identical to leading edge of the seat of the case in female die. Prior to fitting the case with forming block in injection mould and withdrawing it therefrom, ring is fitted thereat over larger OD on female die at aligning the ring surface with smaller OD with female die inner surface to fasten the ring with female die. Then, the case of forming block is fitted on the ring to connect said case with male die or to disconnect said case from male die. Now, the ring is removed from female die.

EFFECT: higher quality of maintenance, application in production of ESH articles at sufficient manufacturability.
