Abstract

The utility model discloses a die base which comprises an upper die base and a lower die base, wherein the lower die base is of a square structure, and a first groove is further arranged in the middle portion of the lower die base. The upper die base is arranged above the lower die base, and an open mouth is installed at one end of a joint which connects the first groove and the upper die base. The die base is characterized in that an anti-wear layer is coated on the open mouth. The anti-wear layer is added, the anti-wear effect is increased, and therefore abrasions of the die base caused by collisions and continuous frictions in the use process are reduced, service life of the die base is prolonged, and manufacture cost is reduced.

Description

A kind of die holder

Technical field

The utility model relates to a kind of die holder, particularly can increase wearability, a kind of die holder that is used for the screw moulding that increases the service life.

Background technology

Screw is a kind of quite general latch members, so demand is very big, present cold working industry generally all is to use mould molding, and the general employing of present mould all is that the tempering material is made.In the continuous use of mould, mould will constantly rub, and causes the wearing and tearing of mould, has reduced the service life of mould, thereby the screw amount that mould is processed reduces, and has increased the cost of producing screw.

The utility model content

An aspect according to the utility model; A kind of die holder is provided, has comprised upper bolster and die shoe, said die shoe is a square structure; The middle part of said die shoe also is provided with first groove; Said upper bolster is positioned at said die shoe top, and the end in said first groove and upper bolster junction also is provided with an opening, and opening part scribbles a wearing layer.

In some embodiments, described wearing layer is wolfram steel, diamond material.Thus, can have the effect that increases rub proofness.

In some embodiments, said die shoe is provided with first through hole that is used for fixing said die holder.The effect that can also have thus, convenient fixing said die holder.

In some embodiments, said upper bolster is provided with and corresponding second through hole of said first through hole, and said second through hole is greater than said first through hole.Thus, can also have the effect that keeps surface smoothness.

In some embodiments, said upper bolster is an arcuate structure, and the side that said upper bolster is relative with said opening also is provided with one second groove, is provided with first screw hole in the said groove.Thus, can also convenient fixing said mould.

In some embodiments, said upper bolster side also is provided with some second screw holes.Thus, can also reduce the error that said mould in use produces.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Fig. 1 has schematically shown a kind of die holder according to a kind of embodiment of the utility model.Shown in Fig. 1-4, this device comprises upper bolster 2 and die shoe 3, and said die shoe is a square structure, and the middle part of said die shoe also is provided with first groove 4, and said upper bolster 2 is positioned at said die shoe 3 tops.In order to be placed to type die in said die holder,, can mould be placed in the said opening so also be provided with an opening 5 at an end of said first groove 4 and upper bolster 2 junctions.Because of mould and said die holder in the process of using are constantly colliding and friction; Constantly worn and torn in opening 5 places of said die holder; Influence the quality of shaped screw and the service life of die holder; In order to reduce owing to the wearing and tearing of constantly colliding between mould and the die holder 1 and friction produces, so scribble one deck wearing layer 6 at said opening 5 places.The die holder 1 that makes amount of reducing wear as far as possible in the process of using, the service life of improving die holder.Because wolfram steel, diamond etc. all belong to carbide alloy in known alloy; Have hardness height, wear-resisting, a series of premium properties such as the good toughness of intensity is better, heat-resisting, corrosion-resistant; Particularly its high rigidity and wearability are so the high-abrasive material of locating is selected wolfram steel, diamond uniform wearability material for use.Use on the board, in order said die holder 1 to be fixed on so said die shoe 3 is provided with first through hole 7 that is used for fixing said die holder 1.So just can use setting tools such as screw or bolt that said die holder is fixed on the board that uses this die holder very easily.The flatness on die holder 1 surface and for convenience detach in order to guarantee to use the time, so on said upper bolster 2, be provided with and said first through hole, 7 corresponding second through holes 8, said second through hole 8 is greater than said first through hole 1.Said upper bolster is an arcuate structure; For can be from the said die holder of upper fixed; So said upper bolster 2 also is provided with one second groove 9 with said opening 5 relative sides; Be provided with first screw hole 10 in said second groove 9, can be convenient to use screw or bolt and said die holder 1 be fixed on the board from top.And in order can easily from the side said die holder to be fixed; And increase accuracy when in use, thus some second screw holes 11 also be provided with in said upper bolster 1 side, so; Can be with said die holder 1 more firm being fixed on the board; Die holder can not moved in using and colliding, guaranteed mould accuracy in the course of the work, and the precision of the product of producing and quality.

Above-described only is some embodiments of the utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
