In this helical feed assembly, because center-pole and helical-blade are difficult to one-body molded, and helical-blade is laminar substantially, therefore the area of welding position is very little between center-pole and helical-blade, and flowing to direction and can impacting helical-blade of liquid can cause the connection of center-pole and helical-blade to lose reliability after long-term use.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of helical feed assembly of injection machine, helical feed assembly can increase the bonding area of center-pole and helical-blade, even if, after long-term work, also can be guaranteed the stability connecting between center-pole and helical-blade.
For achieving the above object, the utility model provides following technical scheme: a kind of helical feed assembly of injection machine, comprise screw rod and barrel, screw rod comprises center-pole and helical-blade, inner side and the center-pole of helical-blade are welded to connect, the outside of screw rod leaf and barrel matched in clearance, is characterized in that: the outer surface of described center-pole is provided with helical groove, and the inner side of helical-blade is embedded in helical groove and with each sidewall of helical groove and all forms and be welded to connect.
By adopting technique scheme, helical groove the area that can increase helical-blade and center-pole welding position is set, improve the reliability of welding; In addition, even if liquid impacts helical-blade in mobile process, owing to being embedded in helical groove, can there is not play skew in helical-blade, even if helical feed assembly, after long-term work, also can be guaranteed the stability connecting between center-pole and helical-blade.
The utility model is further set to: the surface of described center-pole is piled be welded with hard bimetallic alloy completely.
By adopting technique scheme, increase wearability and the corrosion resistance of screw rod, extend its service life.
The utility model is further set to: described helical-blade adopts spiral shell rib gradient thickness structure to arrange.
By adopting technique scheme, can reduce substantially leakage current, thereby improve injection precision.
The utility model is further set to: the surface of described helical-blade is coated with wearing layer completely.
By adopting technique scheme, make helical-blade in the time that raw material is extruded to injection moulding, effectively prevent the wearing and tearing of granular substance confrontation helical-blade, improve the service life of helical-blade.
