Description
Technical field
The utility model relates to the technical field of punching die structure, is specially a kind of mould structure with salient point location.
Background technology
Existing diel, is shown in Fig. 1, during the downward punching press of mould, and forming punching head punching press action, until die face contact up and down, stop bastinade dead, forming action completes, and is namely located by plane-plane contact; But under actual conditions, due to material thickness tolerance and patrix Hookean spring clearance issues etc., mould is not in and kills state completely, can cause the incomplete problem of forming punching head punching press, impact lower processing procedure online serviceability, makes the performance of product be affected.
Summary of the invention
For the problems referred to above, the utility model provide a kind of with salient point location mould structure, its by face and point cantact spacing, complete the punch action preset after die face is contacted with the upper surface of below positioning convex, guarantee that punch is complete, ensure the performance of product.
A kind of mould structure with salient point location, its technical scheme is such: it comprises lower die structure, the central upper portion of described lower die structure is placed with product to be punched, the both sides of described product to be punched are provided with guide plate, directly over described product to be punched, correspondence is provided with upper die structure, the bottom of described upper die structure is stripper plate, convex under the below of described stripper plate have forming punching head, described forming punching head aims at the position to be punched of described product to be punched, it is characterized in that: the both sides indent of the upper surface of described lower die structure forms locating slot, the bottom of the ejection block of respective side is flush-mounted in described locating slot, the upper surface of described ejection block is higher than the upper surface of described lower die structure, the bottom face of described product to be punched is supported on the upper surface of described ejection block, the upper surface of the described ejection block of both sides is respectively arranged with the positioning convex of epirelief, the height of described positioning convex is identical with the thickness of product to be punched, when guaranteeing that the lower surface of stripper plate contacts with the upper surface of positioning convex, punching press action completes smoothly.
It is further characterized in that:
The positioning convex of the upper surface of the described ejection block of homonymy is at least two, makes the location, upper surface of the lower surface of stripper plate and positioning convex firm;
Position directly over all positioning convex of area covering of described stripper plate, guarantees that the bottom surface of stripper plate fully contacts with the upper surface of positioning convex;
Described positioning convex is specially locating dowel, and the upper surface of described locating dowel is plane, and the upper surface of all described locating dowels is concordant mutually.
After adopting technique scheme, after product orientation to be punched, upper die structure drives stripper plate, forming punching head presses down, until the upper surface of positioning convex is close in the lower surface of stripper plate, the forming punching head now preset has pressed down the complete punching press action treating stamping products, height due to positioning convex is and presets, material thickness tolerance and patrix Hookean spring clearance issues need not be considered, the punch action preset is completed after die face is contacted with the upper surface of below positioning convex, guarantee that punch is complete, ensure the performance of product.
Accompanying drawing explanation
Fig. 1 is existing mould structure schematic diagram;
Fig. 2 is mould structure schematic diagram of the present utility model;
Title in figure corresponding to sequence number is as follows:
Lower die structure 1, product to be punched 2, guide plate 3, stripper plate 4, forming punching head 5, locating slot 6, ejection block 7, positioning convex 8.
Detailed description of the invention
A kind of mould structure with salient point location, see Fig. 2: it comprises lower die structure 1, the central upper portion of lower die structure 1 is placed with product 2 to be punched, the both sides of product 2 to be punched are provided with guide plate 3, directly over product 2 to be punched, correspondence is provided with upper die structure, the bottom of upper die structure is stripper plate 4, convex under the below of stripper plate 4 have forming punching head 5, forming punching head 5 aims at the position to be punched of product 2 to be punched, the both sides indent of the upper surface of lower die structure 1 forms locating slot 6, the bottom of ejection block 7 is flush-mounted in locating slot 6, the upper surface of ejection block 7 is higher than the upper surface of lower die structure 1, the upper surface of the ejection block 7 of both sides is respectively arranged with the positioning convex 8 of epirelief, the height of positioning convex 8 is identical with the thickness of product 2 to be punched, when guaranteeing that the lower surface of stripper plate 4 contacts with the upper surface of positioning convex 8, punching press action completes smoothly.
The positioning convex 8 of the upper surface of the ejection block 7 of homonymy is at least two, makes the location, upper surface of the lower surface of stripper plate 4 and positioning convex 8 firm;
Position directly over all positioning convex 8 of area covering of stripper plate 4, guarantees that the bottom surface of stripper plate 4 fully contacts with the upper surface of positioning convex 8;
Positioning convex 8 is specially locating dowel, and the upper surface of locating dowel is plane, and the upper surface of all locating dowels is concordant mutually.
Above specific embodiment of the utility model has been described in detail, but content being only the preferred embodiment that the utility model is created, the practical range created for limiting the utility model can not being considered to.All equalizations done according to the utility model creation application range change and improve, and all should still belong within this patent covering scope.
