The stud height can processed in prior art is generally less than the thickness of steel back of the body flat board.If requiring the stud height D1 of processing, more than the plate thickness D2 of the steel back of the body within 1.0mm, such as stud requires it is to protrude steel back of the body flat board 6.0mm, and the thickness D2 of the steel back of the body is 5.0mm, then the stud height that prior art cannot ensure to process consistent.Stud follows closely high formation instability in punching course, there is deviation；The qualification rate causing product is low, virtually adds the production cost of the steel back of the body.
Utility model content
The purpose of this utility model is to disclose the mould rushing stud, solves existing stud height and forms unstable problem more than the stud nail height within thickness of slab 1.0mm.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
Rush the mould of stud, including lower mold and the upper mold that coordinates with lower mold；Lower mold includes lower bolster and bushing for stud molding, bushing is located in lower bolster；Upper mold includes being located at stripper, the height limit block being located on stripper above lower bolster, is located at the train wheel bridge above stripper and for rushing the main drift of stud, height limit block is between stripper and train wheel bridge, main drift is located at train wheel bridge and through height limit block and stripper, and main drift is positioned at and the position of bushing cooperation.
Further, the affixed described train wheel bridge in rear end of described main drift, the front end of main drift is provided with bevelled edge, and the front elevational sectional of main drift is trapezium structure wide at the top and narrow at the bottom.
Further, described lower mold also includes locating dowel, and locating dowel is located at described lower bolster；Described stripper is provided with the hole, location coordinated with locating dowel.
Further, described lower mold includes die shoe, the lower bolster being located on die shoe, the described lower bolster be located on lower bolster from the bottom to top；Die shoe, lower bolster and lower bolster are affixed by connector.
Further, described upper mold also includes rubber, and rubber is between described stripper and described train wheel bridge.
Further, described rubber height is more than the height of described height limit block.
Further, described upper mold also includes the upper bolster being located on described train wheel bridge；Upper bolster, described train wheel bridge, described rubber and described stripper are affixed by connector.
Further, also including being located at the guide pillar of described train wheel bridge and being located at the guide pin bushing of described lower bolster, guide pillars and bushes is positioned at the position cooperated.
Prior art is compared, the beneficial effects of the utility model:
1, this utility model uses height limit block structure, withstands train wheel bridge when drift drops to height limit block, and the stud of formation reaches anticipated height, and the material that on workpiece, size is unnecessary cannot continue to flow into bushing, it is ensured that stud follows closely high stability and concordance.
2, the front end of main drift is provided with bevelled edge, first, it is ensured that the stud dorsal pore shape of workpiece thus ensure that the intensity of nail；Second, it is to ensure that the concentration flowing of workpiece material, thus in ensureing that material concentrates inflow bushing；3rd, it is ensured that drafting angle, reduce frictional force when of the material returned.The shape changing drift makes workpiece material mobility more preferable so that it is reach the requirement for height of stud.
Stripper is buffered by the structure 3, using rubber, extends the mold use life-span.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
The mould of stud is rushed, including lower mold and the upper mold that coordinates with lower mold as shown in Fig. 1 and Fig. 2 embodiment.Lower mold includes die shoe 1 from the bottom to top, the lower bolster 2 being located on die shoe 1, the lower bolster 3 being located on lower bolster 2, bushing 4 and locating dowel 5 for stud 171 molding, bushing 4 and locating dowel 5 be located in lower bolster 3.Die shoe 1, lower bolster 2, lower bolster 3 are affixed by connectors such as screw rods.
Upper mold include being located at the stripper 6 above lower bolster 3, the height limit block 7 being located on stripper 6, for buffering rubber 8, be located at the train wheel bridge 9 above stripper 6, for the main drift 10 rushing stud 171, the upper bolster 11 be located on train wheel bridge 9 and the die shank 12 being located on upper bolster 11.Height limit block 7 and rubber 8 between stripper 6 and train wheel bridge 9, in the raw under rubber 8 height more than the height of height limit block 7.Main drift 10 is located at train wheel bridge 9 and through height limit block 7 and stripper 6, and main drift 10 is positioned at and bushing 4 positions coordinated.Upper bolster 11, train wheel bridge 9, rubber 8 and stripper 6 are affixed by connectors such as screw rods.Height limit block 7 structure is used to ensure that stability and the concordance of stud 171 height.Described stripper is provided with the hole, location 61 coordinated with locating dowel 5, and during matched moulds, locating dowel 5 through screw rod 17 and stretches in hole 61, location.
Main drift 10 in the present embodiment is in square column type structure, and the affixed train wheel bridge in rear end 101 of main drift, the front end 102 of main drift is provided with bevelled edge 103, and the cross section of the front end 102 of main drift forms trapezium structure wide at the top and narrow at the bottom.Main drift 10 uses the gradient of bevelled edge 103 to set, and has the advantage that first, it is ensured that the stud dorsal pore shape of screw rod 17 thus ensure that the intensity of nail；Second, it is to ensure that the concentration flowing of screw rod 17 material, thus in ensureing that material concentrates inflow bushing；3rd, it is ensured that drafting angle, reduce frictional force when of the material returned.
The present embodiment also includes the guide pillar 13 being located at train wheel bridge and is located at the guide pin bushing 14 of lower bolster, and guide pillar 13 and guide pin bushing 14 are positioned at the position cooperated, it is achieved guide for die sinking, matched moulds.
Further illustrate as to the present embodiment, its operation principle is now described: punch press motion is ordered about upper bolster 11, train wheel bridge 9 and stripper 6 and moved downward, thus drive main drift 10 down punching press, when train wheel bridge 9 and stripper 6 touch height limit block 7 simultaneously, punch press arrives bottom dead centre the most simultaneously, the press height of the most main drift 10 is secured on a height, it is achieved stud 171 high unity.
Other structure of the present embodiment sees prior art.
