Description
Technical field
The utility model is related to technical field of mold, refers in particular to a kind of shaping stamping mold back to squeeze.
Background technology
At present, the products application of hardware stamping Bending Processing is extensive, especially in electronic digital product scope.Existing
In technology, the frame of more and more smart mobile phones is metal (such as aluminium) frame, in order that the metal edge frame ensure that after installing
Appearance is smooth not to be had impression and steps on side, and the molding mode of the structure back to squeeze of existing mobile phone metal edge frame is commonly using secondary
The mode of shaping, the first step carries out punch process by mould to sheet metal, processes in one end-face with downward
Annular bending edges, and R angles are the semi worked pieces of fillet, then processing back to squeeze is carried out to the annular bending edges with mould.Mobile phone gold
The top border of category frame needs bloom chamfering, it is desirable to which outer R angles are less than or equal to a thickness of slab and uniform after the shaping of punching press stock.
In tradition technology back to squeeze, top border R angles are molded using conventional punch stretching structure, and R angles can be thick more than 1.5 times of material, it is impossible to full
Sufficient CNC millings bloom chamfering, milling amount not enough, occurs the unequal bad phenomenon of size after bloom.
Utility model content
The utility model provides a kind of shaping stamping mold back to squeeze for problem of the prior art.
In order to solve above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of shaping stamping mold back to squeeze, including upper die plate and lower template, the middle part of the upper die plate is provided with
Interior de- plate, in the upper end of lower template external stripping plate is provided with, and shaping knot back to squeeze is provided between the external stripping plate and lower template
Structure, the molding structure back to squeeze includes fixed plate and four reverse extrusion blocks, in the lower template, external stripping plate and fixed plate
Between be correspondingly arranged on square opening, the nitrogen spring for support stamp is installed in square opening, the reverse extrusion block point
It is not arranged at four corners of square opening.
Wherein, side crushing block is respectively arranged with the two side in front and back of the square opening, in reverse extrusion block and side
The lower end of crushing block is equipped with the portion of being fixedly connected, and the reverse extrusion block is fixed respectively with side crushing block by the portion of being fixedly connected
It is installed in fixed plate.
Preferably, the consistency of thickness of the thickness and fixed plate for being fixedly connected portion.
Wherein, the limited block being respectively arranged on the left side and the right side for limiting die height of the fixed plate, the limited block
Bottom be embedded in fixed plate.
The beneficial effects of the utility model：
Simple structure of the present utility model, molding structure back to squeeze is up extruded material using mode back to squeeze, makes top
Border R angle sections material becomes and piles up, and promotes R angles to diminish and full, meets the requirement of CNC milling blooms chamfering.
Description of the drawings
Fig. 1 is a kind of structural representation of shaping of the utility model stamping mold back to squeeze in closure.
Fig. 2 is a kind of structure decomposition figure of shaping of the utility model stamping mold back to squeeze.
Reference in Fig. 1 to Fig. 2 includes：
1-upper die plate, 2-lower template 3-interior de- plate；
4-external stripping plate, 5-fixed plate, 6-reverse extrusion block；

Specific embodiment
For the ease of the understanding of those skilled in the art, further is made to the utility model with reference to embodiment and accompanying drawing
Explanation, the content that embodiment is referred to is not to restriction of the present utility model.The utility model is carried out below in conjunction with accompanying drawing
Detailed description.
A kind of shaping provided by the utility model stamping mold back to squeeze, including upper die plate 1 and lower template 2, it is described on
The middle part of template 1 is provided with interior de- plate 3, and the upper end of lower template 2 is provided with external stripping plate 4, the external stripping plate 4 and lower mould
Molding structure back to squeeze is provided between plate 2, the molding structure back to squeeze includes fixed plate 5 and four reverse extrusion blocks 6, described
The centre of lower template 2, external stripping plate 4 and fixed plate 5 is correspondingly arranged on square opening 7, is provided with for supporting punching press in square opening 7
The nitrogen spring 8 of part 11, the reverse extrusion block 6 is respectively arranged at four corners of square opening 7.
In the utility model, side crushing block 9 is respectively arranged with two side before and after the square opening 7, reverse
Crushing block 6 is equipped with the portion of being fixedly connected with the lower end of side crushing block 9, and the reverse extrusion block 6 and side crushing block 9 lead to respectively
Cross the portion of being fixedly connected to be fixedly installed in fixed plate 5.
After hardware products are stamped drawing and forming into semi-finished product, carry out carrying out R angles around it using the utility model
Compression is back to squeeze.Specifically, five metals semi-finished product positioning is positioned over upper nitrogen spring 8, starts lathe upper die plate 1 is de- with outer downwards
The matched moulds of plate 4, interior de- plate 3 is fitted during pushing with five metals semi-finished product；When upper die plate 1 continues to be pressed downward, four are reversely squeezed
