The lower die includes the lower die holder, lower bolster and lower template set gradually from bottom to up, and the lower bolster is fixed on On lower die holder, the lower template is fixed on lower bolster, and the lower template is equipped with the 6th through-hole, the middle part of the 6th through-hole Equipped with vertical block, the vertical block is fixed on lower bolster, and the upper end of the vertical block is equipped with the second through slot, second through slot downwards Positioned at the underface of the first through slot, the cross section semicircular in shape of second through slot, the lower template is equipped with the 7th through-hole, institute The lower end for stating the 7th through-hole extends in lower die holder, and the sliding shoe being adapted to it, the sliding shoe are equipped in the 7th through-hole Positioned at the underface of convex block, the upper end of the sliding shoe exceeds the upper surface of lower template, sets between the sliding shoe and lower die holder There is second spring, the upper end of the sliding shoe is equipped with horizontal cylinder, and the cylinder is located at the underface of the first through slot, the circle Column is located at the surface of the second through slot, and link slot is equipped between the 6th through-hole and the 7th through-hole, and the link slot is located at circle The underface of column, first through slot, cylinder and the second through slot constitute the type of a circular ring shape after the upper die and lower die are closed Chamber.

Further, the upper surface of the lower template is equipped with two pieces of positioning plates, and two pieces of positioning plates are pair with the second through slot The two sides for claiming axial symmetry that the second through slot is arranged in, the upper surface of the opposite end of two positioning plates is respectively provided with placement item The locating slot at the both ends of material.

Further, at least two guide posts, the guide post is installed on the upper padding plate to be evenly distributed on around first through hole, The lower end of the guide post sequentially passes through downwards the lower section that stripper plate is reached after upper clamp plate, baffle plate and stripper plate, in the lower die Equipped with multiple guide holes, multiple guide holes and multiple guide posts face one by one.

Further, the lower end surface of the stripper plate is equipped with multiple limited posts, and multiple limited posts are uniformly distributed in second Around through-hole.

By adopting the above-described technical solution, the beneficial effects of the utility model are:

1, when using a kind of bush mould provided by the utility model, billot made of being punched first is placed on vertical The upper end of block makes the length direction of billot perpendicular to the axis of the second through slot, so that the position in the middle part of billot is substantially aligned with second logical The center line of slot, driving upper mold move downward, and during upper mold moves downward, the convex block first on stripper plate is pressed in sliding On block, sliding shoe is pulled down, second spring is compressed, and the cylinder on sliding shoe moves downwardly in link slot, cylinder to Under press billot, by the second through slot of indentation of billot, be pressed in billot between the cell wall and cylinder of the second through slot, by item The arc-shaped of opening upwards is bent into the middle part of material, the both ends of billot are upturned, at this point, the resistance due to cylinder by vertical block Gear, sliding shoe cannot continue to be pressed downward dynamic, and convex block, stripper plate and baffle plate are stopped and cannot continue to move downward；So The upper die holder in upper mold, upper padding plate and upper clamp plate continue to move downward and compress the first spring afterwards, and upper die is with upper padding plate Slowly move downward, the side of the two opposite sides of the first through slot respectively with two end in contact of the tilting of material strip, due to the first through slot Parabolic, the side wall of the two opposite sides of the first through slot is gradually drawn close from bottom to up, during continuing to move downward, Under the gathering effect of one through slot two sidewalls, the both ends of billot are pressed in opposite directions, until the both ends of billot and the top of the first through slot Contact, the both ends of billot, which are depressed into, at this time is tightly attached on cylinder, and billot is pressed into positioned at the first through slot, cylinder and the second through slot structure At the bushing of the intracavitary circular ring shape of the type of circular ring shape, that is, complete the molding of bushing.Only a punching press is needed just to complete bushing Molding, handling ease, processing cost is greatly saved in high production efficiency.

2, the upper surface of lower template is equipped with two pieces of positioning plates, and two pieces of positioning plates are symmetricly set on using the second through slot as symmetry axis The two sides of second through slot, the upper surface of the opposite end of two positioning plates are respectively provided with the locating slot for placing the both ends of billot. It is convenient that billot is positioned, only need the positioning both ends of billot being individually positioned on two pieces of positioning plates when placing billot In slot, the middle part of billot just can be substantially aligned with the center line of the second through slot, more convenient to use.

3, at least two guide posts, guide post is installed on upper padding plate to be evenly distributed on around first through hole, the lower end of guide post to Under sequentially pass through the lower section that stripper plate is reached after upper clamp plate, baffle plate and stripper plate, lower die is equipped with multiple guide holes, multiple guide holes With multiple guide posts face one by one.Guide post and guide hole cooperation are oriented to upper mold, are not easy upper mold during moving downward It shifts.

4, the lower end surface of stripper plate is equipped with multiple limited posts, and multiple limited posts are uniformly distributed in around the second through-hole.On Mould moves downward, and the convex block on stripper plate pulls down sliding shoe, until the middle part of billot is pressed by the cylinder on sliding shoe In first through slot, when the bottom of the lower surface at the middle part of billot and the second through slot contacts, the lower end of limited post and lower template it is upper Surface is inconsistent, is supported on stripper plate and baffle plate with being balanced above lower template, it is not easy to run-off the straight.
