12), this isosceles trapezoidal column body (4
11) height be the high H of final molding intermediate plate, the upper base hem width equates that with the small end external diameter of final molding intermediate plate the hem width of going to the bottom equates bottom semicircular cylinder (4 with the big end outer diameter D of final molding intermediate plate
12) the semicircle diameter nd of longitudinal section
4Be final molding intermediate plate internal diameter nd, the semicircle central horizontal, the step that is used for locating punch semicylinder position between isosceles trapezoid cylinder and semicylinder is lower than semicircle center h
6, h
6=0.5～1mm;
The punch (5 of d, described mould III (5)
1) projection section and final molding intermediate plate (1
5) match, promptly boss top is divided into isosceles trapezoid cylinder (5
11), the bottom is a semicylinder (5
12), isosceles trapezoid cylinder (5
11) trapezoidal height be the high H of final molding intermediate plate, the upper base hem width is a final molding intermediate plate (1
5) the small end outside diameter d, the hem width of going to the bottom is the big end outer diameter D of final molding intermediate plate, semicylinder (5
12) the longitudinal section be semicircle, the outside is the thread form of the outer tooth of band, the step that is used for locating punch semicylinder position between isosceles trapezoid cylinder and semicylinder is lower than semicircle center h
