Abstract
A kind of combination type unloading bolt, is made up of screw, packing ring and position-limiting tube；The diameter of bore of described packing ring and the diameter matches of thread segment on screw, the external diameter of packing ring is more than the external diameter of screw upper cap nut, and gasket sleeve is connected on the thread segment of screw, and the upper surface of packing ring contacts with the lower surface of described nut；The diameter of bore of described position-limiting tube and the diameter matches of described thread segment, the external diameter of position-limiting tube is less than the external diameter of packing ring, position-limiting tube is socketed on the thread segment of screw, and the upper surface of position-limiting tube contacts with the lower surface of packing ring, and on screw, the lower surface of thread segment is positioned at the downside of position-limiting tube lower surface.Advantageous Effects of the present utility model is: propose a kind of combination type unloading bolt, can effectively reduce production loss.
Description
Technical field
This utility model relates to a kind of stripper unloading bolt, particularly relates to a kind of combination type unloading bolt.
Background technology
Unloading bolt is the common part in diel, and its effect is for connecting consolidating above stripper and stripper
Determine plate, the unloading bolt structure of typical structure, position limiting structure is typically set at middle part, the lower end of unloading bolt is provided with even
The screw thread connect；There is the problem that existing unloading bolt is typically all monolithic construction, after damage can only integral replacing,
Cause production cost higher；Further, since the installing hole specification on different moulds is different, it is therefore desirable to the most independent for every kind of mould
Make unloading bolt, cumbersome.
Utility model content
For the problem in background technology, the utility model proposes a kind of combination type unloading bolt, it is improved by: institute
State combination type unloading bolt to be made up of screw, packing ring and position-limiting tube；The diameter of bore of described packing ring and thread segment straight on screw
Footpath is mated, and the external diameter of packing ring is more than the external diameter of screw upper cap nut, and gasket sleeve is connected on the thread segment of screw, the upper surface of packing ring with
The lower surface contact of described nut；The diameter of bore of described position-limiting tube and the diameter matches of described thread segment, the external diameter of position-limiting tube
Less than the external diameter of packing ring, position-limiting tube is socketed on the thread segment of screw, and the upper surface of position-limiting tube contacts with the lower surface of packing ring, spiral shell
The lower surface nailing on thread segment is positioned at the downside of position-limiting tube lower surface.
In actual production, on unloading bolt, the corresponding end connecting screw thread is easiest to damage, and once damages, can only be overall
Change, after using this utility model, when unloading bolt termination is damaged, only the screw in packing ring and position-limiting tube need to be carried out more
Change, unloading bolt just can be made to reuse, the spillage of material being effectively reduced in production, reduces production cost；It addition, adopt
After this utility model, effectively can carry according to the packing ring of the installing hole size Selection various outer diameter size on mould and position-limiting tube
The versatility of high unloading bolt.
Advantageous Effects of the present utility model is: propose a kind of combination type unloading bolt, can effectively reduce production and damage
Consumption.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model；
In figure, the title corresponding to each labelling is respectively as follows: screw 1, packing ring 2, position-limiting tube 3.
Detailed description of the invention
A kind of combination type unloading bolt, it is improved by: described combination type unloading bolt is by screw 1, packing ring 2 and position-limiting tube
3 compositions；The diameter of bore of described packing ring 2 is more than screw 1 upper cap nut with the diameter matches of thread segment on screw 1, the external diameter of packing ring 2
External diameter, packing ring 2 is socketed on the thread segment of screw 1, and the upper surface of packing ring 2 contacts with the lower surface of described nut；Described limit
The diameter of bore of position pipe 3 and the diameter matches of described thread segment, the external diameter of position-limiting tube 3 is less than the external diameter of packing ring 2, and position-limiting tube 3 overlaps
Being connected on the thread segment of screw 1, the upper surface of position-limiting tube 3 contacts with the lower surface of packing ring 2, the lower surface of thread segment on screw 1
It is positioned at the downside of position-limiting tube 3 lower surface.
Claims (1)
