Abstract
The utility model discloses a mould protection structure, which comprises a first pin joint piece, wherein, the first pin joint piece is used for pivoting a stripper plate on a match plate; the stripper plate is provided with certain moving distance corresponding to the match plate; the moving range of the stripper plate is limited by the first pin joint piece; an elastic piece is arranged between the stripper plate and the match plate; when the moulds are matched, the elastic piece can be combined with the two match plates and then compressed; the mould protection structure also comprises a second pin joint piece, wherein, the second pin joint piece is arranged at one side of the first pin joint piece; the second pin joint piece is also used for pivoting the stripper plate on the match plate; the stripper plate has certain moving distance corresponding to the match plate; when the moulds are opened, the restoring force of the elastic piece makes the stripper plate separate from the match plate, and the two pin joint pieces play the function of limiting separation, so as to prevent the stripper plate from falling on the match plate and damaging the mould.
Description
Technical field
The utility model relates to a kind of mould protection structure, particularly relates to the mould protection structure that a kind of stripper plate drops.
Background technology
In stamping Die Design, push rod two lock screw after movable general contour sleeve of use of stripper plate or the contour grinding guarantees movable stroke, when mould operates when very fast because contour sleeve or screw are subjected to the effect of bigger spring force often, cause insufficient strength fracture to occur, stripper plate is directly fallen down, situation seriously then can be exploded mould, influences die life.
Summary of the invention
The utility model proposes a kind of mould protection structure that prevents that stripper plate from dropping, solved the drop problem of mold damage of stripper plate.
Technical solutions of the utility model are: a kind of mould protection structure, it comprises: one first articulated part, one stripper plate is articulated in a template, this stripper plate template relatively has certain operating range, motion exceeds this operating range and can be limited by this first articulated part, and also is provided with an elastic component between this stripper plate and template, during matched moulds, two template combinations can make this elastic component compression; Usually this elastic component compression distance is greater than this stripper plate operating range.
Also have one second articulated part, it is arranged at first articulated part, one side, be equally to articulate this stripper plate and template, and certain operating range that the relative template of this stripper plate has, this second articulated part length is longer than this first articulated part.
The utility model is limited to the stripper plate activity on this template by two articulated parts, and stripper plate is carried out duplicate protection, and under the situation that does not influence the stripper plate operate as normal, the protection mould is not damaged.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure when matched moulds.
Fig. 2 is the schematic diagram of the utility model structure when die sinking.
The specific embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
Fig. 1 is the schematic diagram of the utility model structure when matched moulds, as shown in the figure, a kind of mould protection structure, it comprises: one first contour sleeve 200, it is as first articulated part, one stripper plate 30 is articulated in the patrix 20, this stripper plate 30 patrix 20 relatively has certain operating range, this first contour sleeve 200 is limited in stripper plate 30 motions within this operating range, make stripper plate 30 can not break away from this patrix 20 and drop, and this stripper plate 30 and 20 of patrixes also be provided with a spring 220, during matched moulds, patrix 20, counterdie 21 combinations make this spring 220 compressions; Usually these spring 220 compression distances can apply big pressure to stripper plate 30 greater than these stripper plate 30 operating ranges.
Also be provided with one second contour sleeve 210 in this protection structure, it is as second articulated part, and it is arranged at first contour sleeve 200 1 sides, is to articulate this stripper plate 30 and patrix 20, certain operating range that these stripper plate 30 relative patrixes 20 have equally; These second contour sleeve 210 to the first contour sleeve 200 long 3-5mm, stripper plate 30 operating ranges that make this second contour sleeve 210 limit are greater than or equal stripper plate 30 operating ranges that the first contour sleeve 200 is limited.
Fig. 2 is the schematic diagram of the utility model structure when die sinking, as shown in the figure, when die sinking, patrix 20, counterdie 21 separately, this spring 220 is released, spring 220 restoring forces can allow this stripper plate 30 and patrix 20 disengaging movement certain distances, take off material and reach; After move distance reached the operating range that this first contour sleeve 200 limited, this stripper plate 30 was defined and unlikely disengaging patrix 20; But when mould operates when very fast, if the first contour sleeve 200 is subjected to the effect of bigger spring 220 power for a long time, can cause the first contour sleeve 200 fracture to occur and stripper plate 30 is dropped, this stripper plate 30 will obtain the qualification of the second contour sleeve 210, this stripper plate 30 can not be dropped and damage counterdie 21.
Because this second contour sleeve 210 is longer than this first contour sleeve 200, makes it can not influence the normal operation of the first contour sleeve 200; But when first contour sleeve 200 damages, fracture, this second contour sleeve 210 can limit this stripper plate 30, and it is come off from patrix 20.
Claims (5)
