PRESSING MOULD FOR MANUFACTURE OF DOWELS FROM POLYMERIC MATERIAL Russian patent published in 2018 - IPC B29C45/26 

FIELD: machine engineering.

SUBSTANCE: pressing mould for manufacture of dowels made of polymeric material contains movable (1) and stationary (2) dies, forming surfaces (3), forming nests (4), forming the shape of the dowels, punches (5) in the form of thin rods forming in nests (4) central hole of the dowel, pushers (7) with the possibility of pushing out of them a ready-made dowel. The forming nests (4) and the pushers (7) are located in the forming surface (3) of the movable die (1) and are installed along the direction of movement of the movable die (1). The pusher (7) is installed inside each nest (4). The punches (5) are fixed on the stationary die (2) coaxially opposite each nest. On the stationary die (2), a channel (6) for supplying a polymeric material is provided.

EFFECT: increase the productivity due to reduction of dowels manufacturing time.
