Abstract
The utility model discloses a tooth penetrating die structure, which comprises a tooth socket and a stationary die core which are cylindrical, wherein one end of the tooth socket is provided with a model segment for molding an internal thread, the stationary die core and the model segment are coaxial and are contacted. The tooth penetrating die structure is characterized in that the top end of the model segment is provided with an outer frustum side surface which can mold a product tail tooth into a screw tooth structure, and the outer frustum side surface rotates and is symmetrical through the middle shaft of the tooth socket and is convex outwards along the axial direction of the shaft; the minimum radius of the conical surface is smaller than the minor diameter of the model segment; the part of the stationary die core contacted with the model segment is provided with an inner frustum side surface aligned with the outer frustum side surface. The die with the structure has the advantages that the outer frustum side surface on the tooth socket causes a spiral tooth of the model segment not to be a sharp point herein, the thickness is large, so the die has enough strength and is not easily damaged; therefore the spiral tooth of the product herein is not easy to generate ground material crumbs; and the finished product ratio of products going gauge is ensured.
Description
Technical field
The utility model relates to a kind of structure of mould, specifically is a kind of structure of logical tooth mould.
Background technology
Conventional logical tooth mould, its facing tail tooth place cross section is a wedge angle, if use the mould facing of this conventional structure to twist the production of tooth product, the damage of in its production process because facing tail cusp angle place easily causes product thread place the problem of strand material bits to occur, also can cause product thread tail tooth place that burr are arranged simultaneously, make product strand tooth stripping direction can cross logical no-go gage but can't all-pass, even whole strand tooth product all can't be crossed logical no-go gage.For dealing with this situation, must add another road trimming at above-mentioned strand tooth product in production procedure usually: artificial treatment tail tooth place burr, this step operation make that its cost of labor input of production of strand tooth product is not little.
Therefore a kind of demand is just arranged, be through the facing structure of logical tooth mould being changed, made the strand tooth product tail tooth place of its output can not cause twisting the problem that material is considered to be worth doing, also can can't not crossing logical no-go gage because of the distortion of tail tooth, thereby must increase trimming, cause cost of labor higher.
The utility model content
At above demand, the utility model proposes a kind of structure of logical tooth mould, its technical scheme is as follows:
A kind of structure of logical tooth mould, comprise facing and cover half fuse, the two is a cylindricality, wherein an end of facing has the tooth mould section that is used for the moulding internal thread, described cover half fuse is coaxial with described tooth mould section, and both touch mutually, and the top of described tooth mould section has formable products tail tooth and is the outer round platform side along dental structure, be somebody's turn to do outer round platform side with facing axis rotation symmetry and along the axial evagination of this axle, and the least radius of this conical surface is less than the path on the described tooth mould section; Described cover half fuse with part that tooth mould section is touched mutually have with described outside the interior frustum cone side that agrees with of round platform side.
Preferred person as the technical program, can do following improvement:
The transversal of described inside and outside frustum cone side on its section of one preferred embodiment is with the side facing keeping parallelism of thread on the described tooth mould section to the facing top.
The top, outer round platform side of the described tooth mould section of one preferred embodiment has a planar upper, and described cover half fuse has a bottom surface parallel with described end face.
The described end face and the bottom surface of one preferred embodiment have identical external diameter.
The described facing of one preferred embodiment is a hollow tubular, and described end face is a ring surface.
The round platform groove that the described cover half fuse bottom surface central authorities of one preferred embodiment have indent, the outer imperial palace of this round platform groove is little.
The outer rim of the described round platform groove of one preferred embodiment has chamfering.
The beneficial effect that the utility model brings is:
1。It no longer is wedge angle herein that outer round platform side on the facing makes the thread of tooth mould section, and thickness is bigger, thereby has enough intensity, not fragile, thereby is difficult for making product thread herein the problem of strand material bits to occur, guarantees that also product crosses the yield rate of logical no-go gage;
2. omitted the operation that the later stage manually revises at product tail tooth, provided cost savings.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the utility model embodiment cutaway view;
Fig. 2 is Fig. 1 embodiment three-dimensional cutaway view;
Fig. 3 is Fig. 1 embodiment explosive view;
Fig. 4 is the logical tooth mould cross-sectional schematic of conventional tradition.
The specific embodiment
As shown in Figure 1, the utility model embodiment cutaway view.This cutaway view has been illustrated the duty of embodiment.Tooth mould section 110 on the facing 100 is touched mutually with cover half fuse 200; There are outer round platform side 102 and end face 101 in the top of its dens in dente mould section 110, and correspondence is frustum cone side 202 and bottom surface 201 in cover half fuse bottom has; Inside and outside frustum cone side, fit in twos and closely avoid leak glue in top, bottom surface.Can find out the thread situation of moulding from the product 300.Tail toilet article in product 300 1 sides have suitable dental structure 301.What deserves to be mentioned is that outer round platform side 102 and interior frustum cone side 202 are parallel on the tooth mould section 110 simultaneously towards the facing on facing 100 tops, should also be parallel along two facings of dental structure 301 therefore.
In conjunction with Fig. 2 and Fig. 3 can be from the visual angle of solid the details of solution structure.Tooth mould section 110 on the facing 100 makes product 300 moulding internal threads and its tail toilet article that suitable dental structure 301 be arranged by outer round platform side 102 and interior frustum cone side 202, end face 101 with agreeing with of bottom surface 201 with cover half fuse 200.
Comparison diagram 4, the logical tooth mould cross-sectional schematic of tradition.Be the tooth mould section 110 and cover half fuse 200 shaped articles 300 on the facing 100 equally, different is, and cover half fuse 200 contacts with tooth mould section 110 that part all is the plane, so the tail toilet article of product 300 have horn structure 302 rather than as the suitable dental structure 301 among Fig. 1.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
