Between have for bolt blank by gap, wherein：
Cutter tooth is located on the die mould face of moving platen and quiet template, and cutter tooth is equipped with several, and the working face along die mould face is suitable
Secondary arrangement is mutually parallel between cutter tooth, and each cutter tooth and the axial direction of quiet template and moving platen are in a certain angle；
Moving platen side is equipped with pressing plate, and pressing plate is attached at moving platen side, is moved together with moving platen, has at the top of pressing plate
Raised line, raised line are more than the height of cutter tooth to protrusion on the outside of pressing plate, height, have interval between raised line and cutter tooth, and along pressing plate
It is axially extending.
Specifically, raised line both ends are respectively provided with feed zone and discharging section, between feed zone and discharging section have profiled section with
Plastic section, profiled section deviation obliquely upward, in a certain angle with the axial direction of pressing plate, low order end connects with feed zone, high-order
End is connected by changeover portion with plastic section, and plastic section connects along the axially extending of pressing plate, end with discharging section.
Further, feed zone, discharging section and changeover portion difference are arc-shaped, and the arc radius of feed zone and discharging section is 1~
The arc radius of 100mm, changeover portion are 1~500mm.
Further, the length of feed zone, profiled section and changeover portion is at least the 1/2 of raised line total length, the length of discharging section
At least the 1/10 of raised line total length.
Angle between raised line two sides is 50 °~70 °, has arcwall face, the arc radius of the arcwall face at the top of raised line
For 1~10mm.
The utility model has the advantage of：
The raised line extrusion structure of the dental lamina mold have feed zone and discharging section, convenient for blank pass in and out, profiled section to tiltedly on
Square deviation, highly gradually increases, and annular groove is made gradually to deepen to be molded, and carries out shaping to it using horizontal plastic section, finally makes
Annular groove is shaped, and each section to be all made of circular arc tangent so that dental lamina is unlikely to deform, and is prolonged the service life, and is reduced to bolt core bar
Damage, improve the precision and yields of bolt, annular groove be processed and formed at one time during threading, to improve production effect
Rate.
Description of the drawings
Fig. 1 be the utility model proposes for produce torsional shear type bolt dental lamina mold structural schematic diagram；
Fig. 2 is the side view of pressing plate；
Fig. 3 is the cross-sectional view of pressing plate.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines diagram and specific embodiment, and the utility model is expanded on further.
As shown in Figure 1, the utility model proposes the dental lamina mold for producing torsional shear type bolt include moving platen 1 with it is quiet
Template 2, moving platen are installed in quiet template in the location structure of threading equipment respectively, and moving platen is fitted in quiet template with mutual
The cutter tooth 3 matched, have between moving platen and quiet template for bolt blank by gap, cutter tooth is located at moving platen and quiet template
On die mould face, cutter tooth is equipped with several, and sequentially arranges along the working face in die mould face, is mutually parallel between cutter tooth, each cutter tooth with
Quiet template and the axial direction of moving platen are in a certain angle；Moving platen side is equipped with pressing plate 4, and pressing plate is attached at moving platen side, and dynamic
Template moves together, has raised line 5 at the top of pressing plate, and for raised line to protruding on the outside of pressing plate, height is more than the height of cutter tooth, raised line with
