Detailed description of the invention
This utility model provides a kind of antidrip injection-moulding nozzle, and this utility model simple in construction is easy to use,
Good leak-proof effect, structural stability is strong, and service life is long.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is entered
The description that row is clear and detailed, it is clear that described embodiment is only a part of embodiment of the present utility model,
Rather than whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not doing
Go out all other embodiments obtained under creative work premise, broadly fall into the scope of this utility model protection.
A kind of antidrip injection-moulding nozzle as illustrated in fig. 1 and 2, including nozzle barrel 1, nozzle head 2 and anti-
Leakage device 3, described nozzle barrel 1 lower end is provided with nozzle head 2, and described nozzle head 2 is provided with anti-neglected loading
Put 3；Described leak-proof device 3 include fixing bar 31, spring 32, plug 33, pole 34, drainage screen 35,
Connecting rod 36, chute 37 and slide block 38, be provided with transversal fixing bar 31, institute inside described nozzle head 2
