Definitions
- piston set forth herein is based on the one known by the patent EP0525229A1 of Allper AG, relating to a "Piston, particularly for pushing liquid metal out of a casting cylinder", which, although satisfactorily fulfills With the function and objectives it intends, it presents various aspects that can be improved.
- the piston of the invention is preferably intended for cylinders of injection machines that use vacuum technology.
- this spring ring (8) has a series of transverse grooves (81) alternately practiced at its edges which, in addition to providing an expansive effect, causing once inserted between the external body (3) and the bushing (4 ) Store to press out on said bushing (4), they are suitable, at least those provided on the wide edge of the ring, to receive tapered tips (9) metal that are embedded in them inserted through holes (63) provided for this purpose in the bayonet seal ring (6).
