Gu nut and arc built-in groove upper surface after compressing, release external force, registration, fastening effect is good；Fastening process is complete
Portion completes in mould, easy and simple to handle, and work efficiency is high.
Make it is also preferred that the left positioning stud is stainless steel.
By using technique scheme so that positioning stud intensity is higher, it is not easy to gets rusty and damages, it is ensured that Gu
Fixed firmness, it is the most permanent to use.
It is also preferred that the left positioning stud includes in the middle part of integrated stud bottom, stud and stud top, stud bottom is provided with
The external screw thread coordinated with die bottom plate, cylindrical in the middle part of stud, stud top is provided with the external screw thread that fastening nut coordinates.
By using technique scheme so that the structure of positioning stud stablizing more so that connect the most firm.
It is also preferred that the left stud bottom is M12 external screw thread, being Φ 12 cylinder in the middle part of stud, stud top is M8 external screw thread.
By using technique scheme, reasonably distribute the diameter of stud, adapt to arc built-in groove and the chi of mould
Very little, it is ensured that bonding strength.
It is also preferred that the left fastening nut includes integrated nut top and nut bottom, nut top is lug lid,
Nut bottom is provided with the female thread coordinated with positioning stud.
By using technique scheme, lug lid and arc built-in groove contact area are relatively big, and pressure holding is relatively stable,
It is not easy generation to rock.
It is also preferred that the left nut top is with yi word pattern knob.
By using technique scheme, can be with more convenient labour-saving rotating screw cap.
It is also preferred that the left a diameter of 25mm of nut cap.
By using technique scheme, diameter is relatively reasonable, while pressure holding is stable, without departing from arc built-in groove.
Make it is also preferred that the left fastening nut is plastic material.
By using technique scheme, pressure holding arc built-in groove that can be relatively stable, cost is relatively low, during the demoulding also
Convenience more.
In sum, this utility model has the advantages that registration, and fastening effect is good；Fastening process is whole
Completing in mould, easy and simple to handle, work efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.The most identical parts are with identical accompanying drawing
Labelling represents.It should be noted that the word "front", "rear" used in describing below, "left", "right", "up" and "down" refer to
Being the direction in accompanying drawing, word " bottom surface " and " end face ", " interior " and " outward " refer respectively to towards or away from particular elements geometry
The direction at center.
A kind of arc built-in groove 1 positioning and fastening arrangement in mould 2, including positioning stud 3 and fastening nut 4, location
Stud 3 is made for stainless steel, and fastening nut 4 is made for plastic material.
Positioning stud 3 includes in the middle part of integrated stud bottom 33, stud 32 and stud top 31, and stud bottom 33 is
M12 external screw thread, in the middle part of stud, 32 is 12 cylinders, and stud top 31 is M8 external screw thread.It is provided with screwed hole on the base plate of mould 2,
Threaded with screwed hole in stud bottom 33.
Fastening nut 4 includes integrated nut top and nut bottom 41, and nut top is Φ 25 lug lid
42, nut bottom 41 is provided with the female thread coordinated with stud top 31.The upper surface of arc built-in groove 1 has hole, location, under nut
Threaded through hole, location with stud top 31 in portion 41, and nut top is with yi word pattern knob 43.
