In the prior art, the positioning component of busbar laminated mould has structure shown in Figure 1, comprises locating template 1 and columniform alignment pin 2, and 2 of this alignment pins are used for the location of each conductor layer of busbar and insulating barrier.Alignment pin 2 comprises major part section and microcephaly's section, and microcephaly's section is plugged in the through hole of locating template 1, and adopts interference fits between the through hole of microcephaly's section and locating template 1.Generally, locating template 1 is very thin and material is softer, and alignment pin 2 materials are harder.
In the busbar pressing process, because busbar is different with the characteristic of expanding with heat and contract with cold of mould, the major part section of alignment pin 2 receives radial load; The through-hole wall of microcephaly's section extruding locating template 1; Make the through-hole wall of locating template 1 produce plastic deformation and expansion, cause the gap between alignment pin 2 and the locating template 1 to increase, alignment pin 2 can be loosening, crooked; Even come off, cause the busbar product size to produce deviation.
The utility model content
The utility model has solved in the prior art in the location structure of busbar laminated mould alignment pin and has been prone to produce loosening, crooked or comes off, and causes the technical problem of busbar product size generation deviation.
The utility model provides a kind of location structure of busbar laminated mould, and said location structure comprises locating template, alignment pin and screw; Said locating template is provided with stepped hole, and screw is arranged in the stepped hole from the below of locating template; Said screw comprises the ailhead and nail body of integrative-structure, and wherein ailhead is sunken to the lower surface of locating template, and the nail body of screw extends to the top of locating template; Alignment pin contacts on the nail body that is sheathed on screw and with the upper surface of locating template.
Further, said stepped hole comprises less second section in aperture bigger first section and aperture, second section top that is positioned at first section; The ailhead of screw is positioned at first section, and the nail body of screw is arranged in second section and extends to the top of locating template.
Further, said nail body comprises near the no thread segment of ailhead with away from the thread segment that has of ailhead; No thread segment is positioned at second section of stepped hole, has thread segment to be positioned at the top of locating template.
Further, be interference fits between second section of said no thread segment and stepped hole.
Further, said alignment pin is provided with internal thread, and said internal thread matees with the screw thread that thread segment is arranged of nail body.
The location structure of the busbar laminated mould that the utility model provides through adopting the location structure that is combined by locating template, alignment pin and screw, can be locked at alignment pin on the locating template; Simultaneously in the busbar pressing process; Alignment pin receives radial load, and most of pressure is born on the lower surface of alignment pin, the ailhead end face of screw, the surface of locating template at this moment, and the hole inwall pressurized of the stepped hole of locating template is very little; Therefore the hole inwall can not produce distortion; Then screw can not become flexible, thereby prevents that effectively alignment pin is loosening, crooked or come off, and guarantees that the busbar product size does not produce deviation.

Wherein, 1---locating template, 2---alignment pin, 3---screw, 31---ailhead, 32---the nail body, 321---no thread segment, 322---thread segment is arranged.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of location structure of busbar laminated mould, and is as shown in Figure 2, and said location structure comprises locating template 1, alignment pin 2 and screw 3.Locating template 1 is provided with stepped hole, and screw 3 is arranged in the stepped hole from the below of locating template 1.Screw 3 comprises ailhead 31 and nail body 32, and wherein ailhead 31 is sunken to the lower surface of locating template 1, and nail body 32 extends to the top of locating template 1.
As shown in Figure 2, stepped hole comprises less second section in aperture bigger first section and aperture, and second section top that is positioned at first section.The ailhead 31 of screw 3 is positioned at first section of stepped hole, and nail body 32 is arranged in second section of stepped hole and extends to the top of locating template 1.
In the utility model, first section the degree of depth of stepped hole guarantees that more than or equal to the height of ailhead 31 ailhead 31 of screw 3 sinks in the locating template 1.
The nail body 32 of screw 3 extends to the top of locating template 1 in second section of stepped hole.Particularly, the nail body 32 of screw 3 is the two-part structure, promptly near the no thread segment 321 of ailhead 31 with away from ailhead 31 thread segment 322 arranged.Wherein, the no thread segment 321 of nail body 32 is positioned at second section of stepped hole, and has thread segment 322 to be positioned at the top of locating template 1.
In the utility model, be interference fits between second section of the no thread segment 321 of nail body 32 and stepped hole, to guarantee that assembling back screw 3 can not become flexible.
