Abstract
The disclosure relates to a side gate nozzle comprising a body with at least one slot for receiving at least one tip insert. The nozzle further comprises a tip insert comprising at least one tip element being in a mounted position arranged in the at least one slot and an expander clamping in an expanded position the tip insert with respect to a bottom of the slot and at least one thereto opposite bearing surface arranged at an undercut.
Claims19
A side gate nozzle (1) comprising
- a. a body (2) with at least one slot (3) for receiving at least one tip insert (4);
- b. a tip insert (4) being in a mounted position arranged in the at least one slot (3);
- and
- c. an expander (5) clamping in an expanded position the tip insert (4) with respect to a bottom (6) of the at least one slot (3) and at least one thereto substantially opposed bearing surface (7) arranged at an undercut (8).
The side gate nozzle (1) according to claim 0, wherein the expander (5) is at least temporarily interconnected to the tip insert (4) such that the expander (5) is movable together with the tip insert (4) during insertion and/or removal of the tip insert (4).
The side gate nozzle (1) according to claim 0, wherein the clamping element (9) is integrally connected to a tip insert body (10) of the tip insert (4) in a deformable manner, in particular at a joint region (11).
The side gate nozzle (1) according to claim 0, wherein the clamping element (9) is expandable by a threaded member (12) arranged in an opening (23) of, or integrally connected to, the clamping element (9) pressing against the tip insert body (10), thereby expanding the clamping element (9) away from the tip insert body (10).
The side gate nozzle (1) according to claim 0, wherein the clamping section (18) of the tip insert (4) has a lateral width greater than the front section (21) of the tip insert (4) comprising at least one tip (28).
The side gate nozzle (1) according to claim 0, wherein the actuating contour (22) is formed as the opening (23) of the clamping element (9) attached to the tip insert body (10).
The side gate nozzle (1) according to claim 0, wherein the outlet (24) of the body melt channel (25) and the inlet (26) of the tip insert melt channel (27) are aligned, in particular concentrically with respect to each other, in the mounted position of the tip insert (4).
