Preferably: when the upper mold and the lower die are closed, strip plane domain keeps the gap of 0.45mm.
Preferably: when the upper mold and the lower die are closed, in last one area of shaping, upper mold area is higher by 0.05mm.
By adopting the above technical scheme, by being provided with the lower die of cavity plate and with the upper mold of fuse, a kind of miniature double end filter is formd
Wave module lead drawing die.By being equipped with the higher intermediate incline of a surface smoothness and surface in the opening in cavity plate
More coarse fuse side, so that stretching more smooth and stretching rear wall will not be thin by drawing.What the technical program was produced
Small, side wall will not be thin by drawing with lead internal diameter for lead, and the advantage that mechanical strength, shock strength are high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of miniature one embodiment of double end filter module lead drawing die of the utility model；
Fig. 2 is the front view of the product of the miniature double end filter module lead drawing die production of the utility model；
Fig. 3 is the perspective view of the product of the miniature double end filter module lead drawing die production of the utility model.
In figure, 1- fuse, 2- lower die, 21- intermediate incline is round, the first cavity plate of 22- portion, the inclined surface 23-, and 24- second is recessed
Mould portion.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to Fig.1, the utility model proposes a kind of miniature double end filter module lead drawing dies, including upper mold is under
Mould 2, upper mold have cylindrical core 1, and lower die 2 is provided with female die for forming, and cavity plate includes from downward first recessed in the upper surface of lower die 2
The diameter in mould portion 22 and the second cavity plate portion 24, the first cavity plate portion 22 is greater than the second cavity plate portion 24, and the first cavity plate portion 22 is close to lower die 2
Upper surface location be provided with intermediate incline 21, intermediate incline 21 is the angle R extended to cavity plate shaft core position, the table of intermediate incline 21
Face finish is 0.05 μm.
It should be noted that the product that this mold is produced, structure such as Fig. 2,3.For with such product, by 0.4 millimeter
Thick electrolytic copper foil, being stretched to diameter is two millimeters of cylinders, and front retains two lateral plates, not only thin without drawing, but also without drawing crack (tool
Have product electrical property good, the advantages of high mechanical strength), which passes through 12 drawing and formings.
Referring to Fig. 2 and Fig. 3, the wall for the lead that the technical program is produced has drawing 6.8mm, diameter 2mm, and diameter error is
Positive and negative 0.01mm, side wall are had excellent performance without thin also not drawing crack is drawn.And lead is drawn to so growing in the prior art, will draw thin, shadow
Ring mechanical strength, electrical property.
It should be noted that the section of the fuse 1 is circle, which is also round hole.
Preferably: the junction in the first cavity plate portion 22 and the second cavity plate portion 24 is from the first cavity plate portion 22 to the second cavity plate portion
The inclined surface 23 that 24 inclinations extend.The diameter in the first cavity plate portion 22 is 0.2mm bigger than the diameter in the second cavity plate portion 24.The side of fuse 1
Axle center inclination towards fuse 1, tilt angle are 1 degree.The upper surface of cavity plate and lower die 2 is coated with one layer of lubricant layer.Upper mold and under
When mould 2 is closed, strip plane domain keeps the gap of 0.45mm.When upper mold and lower die 2 are closed, in last one area of shaping, upper mold
Area is higher by 0.05mm.
By adopting the above technical scheme, the upper mold by being provided with the lower die 2 of cavity plate and with fuse 1, forms a kind of miniature double end
Filter module lead drawing die.By the opening in cavity plate be equipped with the higher intermediate incline 21 of a surface smoothness, and
More coarse 1 side of fuse in surface, so that stretching more smooth.The lead that the technical program is produced has lead internal diameter
It is small, and the advantage that mechanical strength, shock strength are high.
This mold has several particular points.
1, the conjunction of upper and lower mould 2 is closed, and strip plane domain keeps the gap of 0.45mm, and strip is not pressed in guarantee, so as to drawing resistance
