Detailed description of the invention
Fig. 1 is the diagrammatic cross-section that the utility model bull plastic emitting nozzle is installed in mold；
Fig. 2 is the perspective view of an embodiment of the utility model bull plastic emitting nozzle；
Fig. 3 is the schematic diagram of another angle of the nozzle of bull plastic emitting shown in Fig. 2.
Specific embodiment
Below with reference to each attached drawing, the utility model is described in detail.
It please refers to shown in Fig. 1-3, the utility model provides a kind of bull plastic emitting nozzle, comprising: nozzle fuse 1, nozzle are led
Stream connector 2, nozzle positioning sleeve 3, heater 4 and several nozzle heads 5, the nozzle guide connector 2 are sheathed on the spray
1 outside of mouth fuse, the heater 4 are embedded in the nozzle guide connector 2 to heat to the nozzle guide connector 2,
The nozzle positioning sleeve 3 is set to the outside of the nozzle guide connector 2, and several nozzle heads 5 are installed on the nozzle positioning sleeve 3
Lower end.
The nozzle fuse 1 has cavity 101, and the upper end of cavity 101 is feed inlet, and the lower end of cavity 101 is connected with number
A tap hole 102, the nozzle guide connector 2 are equipped with several diversion trenches 201, and the both ends of the diversion trench 201 are separately connected
The outer wall of the tap hole 102 and the nozzle head 5 is to be directed to 5 outer wall of nozzle head for the fluid in cavity 101.
In use, heater 4 heats nozzle guide connector 2, heat transfer guarantees cavity to nozzle fuse 1
Plastic cement in 101 is in fluid state, and plastic cement fluid is flow to since pressure effect flows into tap hole 102 along diversion trench 201
5 outside of nozzle head, flows into the type chamber of mold 8 finally along 5 outer wall of nozzle head, as shown in Figure 1, direction indicated by arrow is
The flow direction of plastic cement fluid.The bull plastic emitting nozzle of the utility model has several nozzle heads 5, and plastic cement is from nozzle head 5
Outer wall flow into the type chamber of mold 8, that is, there are multiple glue-spreading heads, type chamber many places plastic emitting that can simultaneously to mold 8, thus suitable
For producing multiple independent miscellaneous goods of uniform annular miscellaneous goods or a multi-cavity mold.
Further, several nozzle heads 5 are uniformly distributed in the lower end of the nozzle positioning sleeve 3.Please refer to Fig. 2, shown in 3,
