Abstract
The utility model discloses a stretching die, including install the mould insert (5) last membrane module (1), install the lower mould and insert lower membrane module (9) of (7), die cavity (6) of going up formation product part behind membrane module (1) and time membrane module (9) compound die, lower membrane module (9) go up along the contour's edge of die cavity (6) and be connected with blank holder (3), blank holder (3) along the insert lateral wall annular setting of (7) of lower mould, the top surface of blank holder (3) is close to die cavity (6) contour's edge department and is equipped with and hinders silo (4), the last mould of corresponding position is inserted and is equipped with on (5) and hinders silo (4) complex and hinder the material and break out (8). After adopting this kind of structure, both can reduce the size of raw and other materials, save the cost, can guarantee the rigidity of product again, and make the drawing of material more abundant.
Description
Technical field
This utility model relates to the technical field of mould, is especially a kind of drawing die.
Background technology
At present, a lot of plates all cover plate and interior panels etc. by the many in mould punching molding, such as vehicle, and
Complicated plate is it is generally required to the multistep operations such as stretched moulding, deburring, flange, shaping just complete whole forming process.Logical
Often drawing die includes being provided with the upper die component of upper mold insert, being provided with the lower mold assemblies of lower mold insert, upper die component and lower mold
The die cavity of product parts is formed after assembly matched moulds.But, in actual production, some plate is due to its material behavior, often reaches not
Technology requirement to product parts.Such as aluminium sheet, owing to its material amount of flow when stretching is relatively big, the springback capacity of material is difficult to control
System, therefore, after shaping, often there is the phenomenon of stretching excess, so, the product after molding in the product of these materials
Become large-sized, on the premise of volume of raw material is certain, the intensity of the product in effective dimensions and rigidity certainly will be caused not to reach institute
Needs are asked.People generally use the method increasing volume of raw material, solve this problem, but, certainly will add and produce into
This.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of minimizing raw material size, thus cost-effective, and energy
Ensure the drawing die of product rigidity.
For solve above-mentioned technical problem, this utility model provide drawing die, including be provided with upper mold insert upper die component,
The die cavity of product parts is formed after the lower mold assemblies of lower mold insert, upper die component and lower mold assemblies matched moulds are installed；Described lower mold
On assembly, the contour edge connection along die cavity has blank holder, and blank holder is arranged along the sidewall annular of lower mold insert, the end face of blank holder
Being provided with resistance material groove at die cavity contour edge, the upper mold insert of opposite position is provided with the resistance material projection with resistance material slot fit.
The cross section of described resistance material groove is arc, and the cross section of corresponding resistance material projection is also arc.
Being positioned by alignment pin between described blank holder and lower mold assemblies, this alignment pin is connected by screw and lower mold assemblies are fixing.
The end face of described blank holder is inclined-plane, and near one end of lower mold insert less than the one end away from lower mold insert.
After using the drawing die of said structure, this utility model compared with prior art, has the advantage that
1) owing to being provided with blank holder in the edge near die cavity, and on blank holder, it is provided with resistance material groove, so has preferably
The raw material of ductility is flowing at resistance material groove, hindered, and raw material just flowing is so far, will not the most unrestrictedly to
Outer flowing extends, thus has better controled over raw-material amount of flow, therefore, both can reduce raw-material size, and save into
This, can ensure that again the rigidity of product, and the stretching making material is more abundant；
2) the arc-shaped cross-section design of resistance material groove, on the one hand prevents raw-material flowing, on the other hand also makes raw-material flowing
More smooth, it is to avoid to produce stress at material internal；
3) blank holder is located by connecting with the alignment pin of lower mold assemblies, and the position making blank holder is more accurate, also makes whole pair of drawing die
Product Precision higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model drawing die.
Wherein: 1, upper die component；2, alignment pin；3, blank holder；4, resistance material groove；5, upper mold insert；6, die cavity；7、
Lower mold insert；8, resistance material projection；9, lower mold assemblies.
Detailed description of the invention
With detailed description of the invention, this utility model is described in more detail below in conjunction with the accompanying drawings.
The structural representation stretched in conjunction with this utility model shown in Fig. 1 understands, and it includes the upper module being provided with upper mold insert 5
Part 1, the lower mold assemblies 9 of lower mold insert 7 is installed, after upper die component 1 and lower mold assemblies 9 matched moulds, forms the die cavity of product parts
6.On described lower mold assemblies 9, the contour edge connection along die cavity 6 has blank holder 3, and blank holder 3 is along the sidewall of lower mold insert 7
Annular is arranged, and the end face of blank holder 3 is provided with resistance material groove 4 at die cavity 6 contour edge, the upper mold insert 5 of opposite position
It is provided with the resistance material projection 8 coordinated with resistance material groove 4.
The cross section of described resistance material groove 4 is arc, and the cross section of corresponding resistance material projection 8 is also arc.
Being positioned by alignment pin 2 between described blank holder 3 and lower mold assemblies 9, this alignment pin 2 is by screw and lower mold assemblies
9 fixing connections.
The end face of described blank holder 3 is inclined-plane, and near one end of lower mold insert 7 less than the one end away from lower mold insert 7.
The above, be only the most feasible enforcement example of this utility model, it is impossible to the most i.e. limit to right model of the present utility model
Enclose, for those skilled in the art, all utilization the technical solution of the utility model and technology design make other are each
Plant corresponding change all should belong within this utility model scope of the claims.
