Abstract
The utility model relates to screw technique field, particularly relate to high rotation-speed injection screw rod, it comprises screw body, with the screw shank being arranged at screw body root, described screw body comprises the feed zone, fusion plastification section and the extruding zone that set gradually from the root of screw body to afterbody, the screw thread of described feed zone, fusion plastification section and extruding zone all offers axial " V " type groove, " V " type groove of adjacent thread shifts to install, the resistance suffered by material can be reduced, reduce and damage is caused to screw rod.
Description
Technical field
The utility model relates to screw technique field, particularly relates to high rotation-speed injection screw rod.
Background technology
The operation principle of injection machine is the thrust by screw rod, in the die cavity enter to have closed, obtains the technical process of goods after solidifying and setting by the plastic injection of the molten condition plastified.At present, high rotation-speed injection screw rod, the resistance suffered by material is very large, easily causes damage to screw rod.
Utility model content
The purpose of this utility model is to provide a kind of high rotation-speed injection screw rod for the deficiencies in the prior art, can reduce the resistance suffered by material, reduce and cause damage to screw rod.
For achieving the above object, the utility model adopts following technical proposals: high rotation-speed injection screw rod, it comprises screw body, with the screw shank being arranged at screw body root, described screw body comprises the feed zone, fusion plastification section and the extruding zone that set gradually from the root of screw body to afterbody, the screw thread of described feed zone, fusion plastification section and extruding zone all offers axial " V " type groove, and " V " type groove of adjacent thread shifts to install.
The angle of " V " type groove of described feed zone is 60 °.
The angle of " V " type groove of described fusion plastification section is 45 °.
The angle of " V " type groove of described extruding zone is 30 °.
The beneficial effects of the utility model: high rotation-speed injection screw rod described in the utility model, can reduce the resistance suffered by material, reduce and cause damage to screw rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, high rotation-speed injection screw rod described in the utility model, it comprises screw body, with the screw shank being arranged at screw body root, described screw body comprises the feed zone 1, fusion plastification section 2 and the extruding zone 3 that set gradually from the root of screw body to afterbody, the screw thread of described feed zone 1, fusion plastification section 2 and extruding zone 3 all offers axial " V " type groove 4, and " V " type groove 4 of adjacent thread shifts to install.During work, when material enters feed zone 1, fusion plastification section 2 and extruding zone 3 successively, in the course of work of High Rotation Speed, screw rod provides very large thrust to promote material reach, " V " type groove 4 then can reduce the resistance suffered by material to a certain extent, thus minimizing causes damage to screw rod.
Preferably, the angle of " V " type groove 4 of described feed zone 1 is 60 °, and the angle of " V " type groove 4 of described fusion plastification section 2 is 45 °, and the angle of " V " type groove 4 of described extruding zone 3 is 30 °.The angle of " V " type groove 4 reduces successively from feed zone 1, fusion plastification section 2 to extruding zone 3, can reduce the loss of thrust, can reduce again the resistance suffered by material.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
