Embodiment 1
It is a kind of casted die mould 100 of dust cover provided in this embodiment with reference to figure 1, in figure, is used for vehicle dust protector
Manufacture.The lower die holder 120 of the casted die mould 100 of dust cover is equipped with guide post 130, in the raised dust cover structure of punching press
When, ram efficiency is high and stamping quality is good.
What the casted die mould 100 of the dust cover in the present embodiment was specifically formed by：
A kind of casted die mould 100 of dust cover comprising upper die holder 110 and lower die holder 120, lower die holder 120 is along vertical side
To closer or far from upper die holder 110.Upper die holder 110 is equipped with circular boss 111；It is offered on the center location of boss 111
Through-hole 113.
The auxiliary section 131 being adapted with boss 111 is offered on lower die holder 120；The casted die mould 100 of dust cover further includes
Auxiliary section 131 is stretched out in one end of the guide post 130 being connect with lower die holder 120, the guide post 130.Upper die holder 110 by through-hole 113 with
Guide post 130 is slidably connected closer or far from lower die holder 120, to be carried out to plate when upper die holder 110 is close to lower die holder 120
Punching press, to which required part be made.
Upper die holder 110 has the first forming surface 133 close to the side of lower die holder 120, and boss 111 is close to lower die holder 120
Side has the second forming surface 135.It is suppressed due to the boss 111 of compression moulding in actual use and the first forming surface 133
Usually there is transition between structure, therefore in the present embodiment, pass through transition between the first forming surface 133 and the second forming surface 135
Face 137 connects.
Further, in the present embodiment, transition face 137 includes being connected far from side on 135 direction of the second forming surface
Annular surface and inclined-plane.And according to the needs of actual use, the second forming surface 135, annular surface and inclined-plane side are close to the first one-tenth
Type face 133.It should be noted that in other specific implementation modes, above-mentioned transition face 137 can also be other structures.
Optionally, due to the needs that punch process and dust cover produce, the first forming surface 133, the in the present embodiment
The surface roughness Ra of two forming surfaces 135, annular surface and inclined-plane is not more than 0.8.Surface roughness refers to what finished surface had
Smaller spacing and small peak valley unevenness.The distance between its two wave crest or two troughs very little belong to microcosmos geometric shape error.
Surface roughness is smaller, then surface is more smooth；The size of surface roughness has prodigious shadow to the performance of machine components
It rings.Non-forming face controls surface roughness Ra below 3.2 in the present embodiment.
It is additionally provided with lug boss 115 on 110 the first preset direction of upper edge of upper die holder, the lug boss 115 is for processing downwards
120 direction of die holder shape outstanding, for subsequently continuing processing and forming.115 side of lug boss is connect with inclined-plane.It needs
Illustrate, in other specific implementation modes, according to actual needs, above-mentioned lug boss 115 can be not provided with.
It is in the present embodiment, separate in the first forming surface 133 in order to intercept a part of template workpiece in punching course
Flange protrusion is additionally provided on side not together, correspondingly, lower die holder 120 is equipped with the flange protrusion to the recess of adaptation
Portion.When upper die holder 110 is moved along guide post 130 to lower die holder 120, flange protrusion is matched with recessed portion, by a workpiece part
Shape contour along flange protrusion intercepts, and is processing at one time molding and cutting, is reducing workflow.
In order to further ensure the accuracy of processing, in the present embodiment, upper die holder 110, which is equipped with, matches zygostyle 140, lower die
The matching hole for offering on seat 120 and being adapted with zygostyle 140.When upper die holder 110 along guide post 130 close to lower die holder 120 when, match
Zygostyle 140 is inserted into matching hole, and is slided along matching hole, and guiding role is played, and ensures that entire punching course is steady and accurate,
Improve the precision of production.It should be noted that in other specific implementation modes, the above-mentioned quantity with zygostyle 140 is according to reality
Need to be arranged multiple, and position can be changed, and can additionally be not provided with above-mentioned matching zygostyle 140.
Upper die holder 110, lower die holder 120 and guide post 130 are made and are heat-treated using Cr12 materials in the present embodiment, are protected
Demonstrate,prove HRC 56 ~ 60.The casted die mould 100 of the dust cover targetedly improves the ram efficiency of vehicle dust protector, and punching press
It is high-quality, shorten process, saved at production cost.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
