Embodiment
Below against attached drawing, by the description of the embodiment, making to embodiment of the invention further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
Structure of the invention as shown in Figures 3 to 6, is a kind of extrusion die supporting plate, equipped with cavity 3.
In order to and the defects of overcome the prior art, realize the goal of the invention for reducing labor content, reducing material cost, this
Inventing the technical solution taken is：
As shown in Figures 3 to 6, extrusion die supporting plate of the invention, the extrusion die supporting plate are equipped with 1 He of template
Core 2；1 bottom surface of template is overlapped with an end face of core 2；The height of the core 2 is more than the thickness of template 1；
The cavity 3 is formed by the gap between shape side in template 1 and the shape side of core 2.
Fig. 3 and Fig. 4 is the processing method of the present invention, is mounted in mold insert, obtains by cavity and the independent work of core, then by core
It is embedded support harden structure to required workpiece.The present invention is processed by way of core is inlayed with supporting plate, is saved
Material, reduce cutter and the loss of wire cutting silk, reduce cost and ensure to produce the product for meeting related quality criterion.
The shape side of the core 2 is equipped with multiple outside core fixed lobes 4；The template 1 is equipped with
The groove being adapted with 4 shape of core fixed lobe；The core fixed lobe 4 is embedded in groove.
On four faces of outer surface of the core 2, each face is designed with two cores with T-shape structure and fixes
Protrusion 4；Corresponding to core fixed lobe 4 on four faces of medial surface of the template 1, each face is designed with two and carries T-shape
The groove of structure；
The groove is with setting trip bolt 5 on the faying face of core fixed lobe 4；The trip bolt 5 is from template 1
Bottom surface direction loads.
The faying face of the groove and core fixed lobe 4 is by being welded to connect.
Width of the end of the stretching of the core fixed lobe 4 in 2 cross-wise direction of core, is fixed convex more than core
4 width with 2 body coupling part of core are played, are formed on 2 section of core "T"-shaped.
The thickness of the template 1 is 25mm.
The height of the core 2 is 125mm.
The present invention compared with prior art, has the following advantages：
1st, in material set-up procedure, supporting plate material requested only need to be declared, stent plate thickness is generally 25mm, core part
Divide and used when can be substituted with waste mold steel, die steel material consumption greatly reduces.
2nd, in cutting on line process, since the cutting-height of workpiece reduces, original 120-150mm is reduced to existing
25mm, under same cutting path, wire cutting takes reduction, and the consumption of wire cutting silk is also corresponding to be reduced.
3rd, in conventional processing method, after wire cutting is complete, it is necessary to by the excess stock mill off of core part, due to core
Height is higher, and milling workload is very big, and cutter is lost more serious.And in the present invention, since core part is directly logical
Cross linear cutter completion, the process for directly eliminating core milling.
4th, in whole process, each operation is all accordingly simplified, and machining period shortens dramatically, and production cost drops significantly
It is low.
In order to realize the goal of the invention identical with above-mentioned technical proposal, present invention also offers extrusion as described above mould
The processing technology of supporting plate, its technical solution are that the processing content of this method includes：
1st, template 1 is processed：
Prepare one piece of plate, after being worked into appearance and size, carry out linear cutter, cut out the cavity portion shape of interior shape
Shape, obtains template 1；
As shown in Figure 3：Machining support plate：Prepare one block of 25mm thickness material, be worked into the laggard line cutting of appearance and size and add
Work, cuts out cavity portion, obtains workpiece shown in Fig. 3；
2nd, core 2 is processed：
Prepare one piece of thick blank material, end face is processed, retain 2mm surpluses；Linear cutter is carried out to lateral surface, is cut
The shape of cavity portion is cut out, obtains core 2；
As shown in Figure 4：Prepare one piece of 127mm thickness blank material, can be substituted by waste mold steel, carry out linear cutter,
Core part is cut out, retains 2mm surpluses, obtains workpiece shown in Fig. 4；
3rd, core is inlayed：
Core 2 is mounted in the groove of template by core fixed lobe 4；
As shown in figure 5, on 4 faces of supporting plate cavity, there are 2 supporting ribs for carrying T-slot structure in each face, shares
8, relevant position also has the supporting rib of 8 same shapes matched on core.Core is mounted to by 8 supporting ribs
In supporting plate cavity, supporting rib is T-slot structure, can play positioning action, ensures the gap between core and cavity, at the same time
There are 2 supporting ribs on each face of cavity surrounding, it is also ensured that core and the verticality of supporting plate self-test.
The 4th, trip bolt is installed：
After the completion of inlaying, a M6 threaded hole is attacked in each core fixed lobe 4 and groove binding site, is then screwed on tight
Gu screw 5 is fastened；
As shown in Figure 6：A M6 screw thread is attacked in the T-slot of every supporting rib, M6 stainless steel yi word patterns is then screwed on and puts down
End tight fixed bolt is fastened.
5th, weld：
Next, making a call to a circle groove around trip bolt 5, then enclosed around cut one and carry out spot welding；
I.e.：A circle cut is made a call to around bolt with rotation rifle, is then enclosed around cut one and carries out spot welding, screw thread can be filled
Gap between bolt, weld mark is will not leave behind after milling；
6th, milling and polish：
Finally, the end face surplus on 5 projection of trip bolt and core 2 on 1 bottom surface of template is milled away；Polish
The surface, machines；
As shown in fig. 6, the 2mm surpluses on bolt projection and core are milled away, flattened surface, you can process
Into.
Above-mentioned new processing technology provided by the invention, the purpose is to ensure the verticality between core and supporting plate
Under the premise of, material, reduction cutter and the loss of wire cutting silk are saved, processing efficiency is improved, reduces cost；And overall processing method
Relatively simple, machining period greatly shortens.By individually being processed with core to supporting plate, then core is embedded in the form of mold insert
Into supporting plate, first pass through the mode that bolt screws in mosaic site and fastened.Then spot welding is fixed around bolt,
After having assembled, mill off surplus is regrinded flat processing and is machined.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Other occasions are directly applied into by the design of the present invention and technical solution, within protection scope of the present invention.
