As shown in fig. 1-5, the utility model provides a nozzle device of mold mechanism, its characterized in that, nozzle device of mold mechanism includes:

the water inlet 1 is used for injecting glue;

the water inlet pipe 2 is arranged below the water inlet 1, and the water inlet pipe 2 can enter and exit the water inlet 1;

the shunt pipe 3 is communicated with the lower end of the water inlet pipe 2; and

and the upper end of the water outlet pipe 4 is communicated with the flow dividing pipe 3, and the lower end of the water outlet pipe 4 is inserted into the inlet of the cavity.

Specifically, the water inlet 1 is fixed on the A plate 8, and the B plate 9 is respectively provided with a cavity through hole 91 matched with the water outlet pipe 4 and a blind hole 92 matched with the limiting block 5 and the bolt 6. Wherein the cavity through hole 91 of the B plate 9 is communicated with an upper cavity fixed on the B plate 9. In detail, the upper end of the water inlet 1 can be flush with the upper surface of the a plate 8, the lower surface of the water inlet 1 is flush with the lower surface of the a plate 8, and the lower surface of the a plate 8 is further provided with a long groove 81 matched with the groove 7 and the shunt pipe 3. Inlet tube 2 is in under water inlet 1, when needing to mould plastics, and inlet tube 2 inserts the first through-hole of recess 7 department, and the raw materials of being convenient for flows into inlet tube 2 department from water inlet 1. When the mould is opened, the A plate 8 is lifted, and the water inlet pipe 2 can be separated from the first through hole. The raw materials flow into the shunt tubes 3 communicated with the water inlet pipe 2 through the water inlet pipe 2 and then flow into the water outlet pipes 4 through the shunt tubes 3 until the raw materials flow into the cavity from the water outlet pipes 4 for molding. Set up rather than fixed connection's stopper 5 in shunt tubes 3 department, pass a bolt 6 on stopper 5, bolt 6's double-screw bolt from down up pass stopper 5 and can make a round trip to slide on stopper 5, insert A board 8 and with A board 8 fixed connection at the top of double-screw bolt, bolt 6 tie the head diameter and be greater than the diameter of the second through-hole on stopper 5, so bolt 6 tie the head and have a limiting displacement to stopper 5 again. When the a plate 8 is lifted, the entire nozzle assembly hangs from the a plate 8 due to the fixed connection of the bolts 6 to the a plate 8.
