Abstract
The utility model provides a kind of mould, for one location convex closure reverse extrusion mould, its counterdie that there is patrix and agree with mutually with it, also there is preformed assembly and reverse extrusion assembly, and both are all positioned at patrix, in counterdie, described preformed assembly comprises forming punching head corresponding up and down, molding concave die, described reverse extrusion assembly comprises shaping upper mold insert corresponding up and down, molding concave die, and shaping low punch, wherein, shaping low punch is active in the groove of molding concave die, the diameter of shaping low punch is less than the diameter of molding concave die, and there is certain interval between the two.The utility model is through two operations, and will carry out reverse extrusion through preformed convex closure, and form annular convex closure, it thoroughly solves the orientation problem in printer between each component, effectively to avoid in printer paper by paperboard problem during parts.
Description
Technical field
The utility model relates to a kind of mould, refers in particular to a kind of location convex closure reverse extrusion mould.
Background technology
Location convex closure is a kind of conventional process in diel, and its effect is accurately located at two components.The material at the convex closure back side, by extruding, forms the outstanding shape that has straight arm section in front, and convex closure straight section be about 50% (as shown in Figure 6) of material stock thickness.Its shortcoming is: 1. the backing material of convex closure flows to front, requires smooth component existing defects to the back side, and its side-wall material intensity is extruded thinning, causes intensity to reduce; 2. for Konica Minolta component, the back side of convex closure be duplicator paper by face, its back side counterbore can affect passing through of paper, there will be the situation of paperboard; 3. the sidewall of convex closure is thinning, the attenuating of intensity, there will be the risk of convex closure fracture.
Summary of the invention
The purpose of this utility model is for the existing state of the art, provides a kind of location convex closure reverse extrusion mould, to solve the smooth problem at the convex closure back side, paper is passed through in the plane, avoid the problem of paperboard, prevent convex closure breakage problem simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
The utility model is a kind of location convex closure reverse extrusion mould, have patrix, with its counterdie agreed with mutually, also there is preformed assembly and reverse extrusion assembly, and both are all arranged in upper die and lower die, described preformed assembly comprises forming punching head and molding concave die, described reverse extrusion assembly comprises shaping upper mold insert, molding concave die and shaping low punch, and wherein, shaping low punch is active in the groove of molding concave die.
Further, described forming punching head is arranged in patrix, and molding concave die is arranged in counterdie.
Further, described forming punching head and molding concave die are corresponding up and down.
Further, described shaping upper mold insert is arranged in patrix, and molding concave die and shaping low punch are arranged in counterdie and are arranged in counterdie.
Further, described shaping upper mold insert is corresponding up and down with molding concave die.
Further, the diameter of described shaping low punch is less than the diameter of molding concave die, has certain interval between the two.
The beneficial effects of the utility model are: convex closure forming method be exactly by convex closure around material and middle material reverse extrusion, material is flowing in a closed annular region, exceeds material face simultaneously, assembling with other component the effect playing location.Preformed: extruded to centre by the material around convex closure by preformed assembly, prevents material in next step forming process from flowing to surrounding.Reverse extrusion convex closure is shaping: by reverse extrusion assembly, the material of centre is extruded thinning extruding, and material is reverse flow in a closed space, finally reaches the annular convex closure in high out-of-plane.It thoroughly solves the orientation problem in printer between each component, effectively to avoid in printer paper by paperboard problem during parts.

detailed description of the invention:
Can have the object of the utility model, feature and function to make juror and further understand, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Refer to shown in Fig. 1-5, it is the structural representation of the preferred embodiment of the utility model, the utility model is a kind of location convex closure reverse extrusion mould, there is patrix 1, the counterdie 2 agreed with mutually with it, also there is preformed assembly 3 and reverse extrusion assembly 4, and both are all positioned at patrix 1, in counterdie 2, described preformed assembly 3 comprises forming punching head 31 and molding concave die 32, wherein forming punching head 31 is arranged in patrix 1, molding concave die 32 is arranged in counterdie 2, and forming punching head 31 is corresponding with molding concave die about 32, material is extruded with molding concave die 32 by the forming punching head 31 in preformed assembly 3, form convex closure, described reverse extrusion assembly 4 comprises shaping upper mold insert 41, molding concave die 42 and shaping low punch 43, shaping upper mold insert 41 is arranged in patrix 1, molding concave die 42 and shaping low punch 43 are arranged in counterdie 2, and shaping upper mold insert 41 is corresponding with molding concave die about 42, shaping low punch 43 is active in the groove of molding concave die 42, wherein, the diameter of shaping low punch 43 is less than the diameter of molding concave die 42, there is certain interval between the two, the material forming convex closure through preformed assembly 3 is processed by reverse extrusion assembly 4, located with molding concave die 42 by shaping upper mold insert 41, aimed at from the bottom to top in the middle of convex closure by shaping low punch 43 and extrude, utilize the gap between shaping low punch 43 and molding concave die 42, it is made to form annular convex closure.
Gong Walk mono-(preformed) during utility model works: coordinated with molding concave die 32 by forming punching head 31, make material under the effect of forming punching head 31, material around convex closure is extruded to centre, in the groove of molding concave die 32, form convex closure, prevent material in next step forming process from flowing to surrounding.Gong Walk bis-(reverse extrusion is shaping): located to material with molding concave die 42 by shaping upper mold insert 41, the convex closure of material is made to be arranged in the groove of molding concave die 42, aimed at from the bottom to top in the middle of convex closure by the shaping low punch be active in molding concave die 42 and carry out reverse impact, the material of centre is extruded thinning extruding, material is reverse flow in a closed space, finally reaches the annular convex closure in high out-of-plane.
Certainly, above diagram is only the utility model better embodiment, not limits the scope of application of the present utility model with this, therefore, every make in the utility model principle equivalence change all should be included in protection domain of the present utility model.
