An apparatus for injection molding of the plasticized plastic material into a mold cavity

摘要

The invention relates to a device for injecting material in a plastic state into a moulding cavity. The inventive device comprises a distributor (11) for said material in a plastic state and an injection nozzle (10) which is connected to the distributor (11) by a detachable connection means (31) and has a front surface (78) which is formed in such a way that it can become integral with the moulding cavity (2). In order to enable the front surface (78) to be positioned in such a way as to permit said integral connection when the nozzle (10) is assembled and re-assembled after dismounting, indexing means (49, 54, 57, 59, 90, 95, 99) are provided for the angular position of said front surface (78) in relation to the distributor, along with locking means (31, 85) fixing said front surface (78) in relation to the distributor (11) in a relative angular position which is imposed by the indexing means (49, 54, 57, 59, 90, 95, 99).
