Abstract
The utility model discloses an improve crystallization graphite mould of copper strips limit portion, it includes platelike last mould, platelike lower mould and two are located go up the mould with the strake of both sides portion between the lower mould, go up the mould the lower mould with the shaping space of strake wall copper strips, the middle part of going up the mould has a plurality of running through go up the inlet opening of mould, a plurality of with on the lower mould the corresponding apopore of inlet opening, its characterized in that be provided with the limit hole on the strake, the limit hole certainly the strake is close to a tip of mould export extends the setting to another tip direction, because the utility model discloses set up the limit hole on the strake, can reduce the cooling rate of copper strips edge portion for the copper strips can secondary crystallization after leaving the mould, makes the edge portion of copper strips be difficult for producing the crackle.
Description
Technical Field
The utility model relates to a metal smelting field, especially a can improve crystallization graphite mould of copper strips limit portion.
Background
The crystal graphite mould has the advantages of high casting speed due to the factors of good heat-conducting property, good self-lubricating property and the like, and the cast ingot has accurate size, smooth surface and uniform crystal structure and can be directly processed in the next procedure. For example, CN 206028671U discloses a graphite mold, which has the advantages of high yield and durability of the mold.
However, if the crystalline graphite mold is used for a long time, the mold edge is easily damaged by oxidation. At this moment, the edge of the copper strip produced by the die is easy to crack, and the produced copper strip can be used only by trimming the edge.
Disclosure of Invention
The utility model aims at providing an improve crystallization graphite mould of copper strips limit portion.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides an improve crystallization graphite mould of copper strips limit portion, its includes platelike last mould, platelike lower mould and two are located go up the mould with the strake of both sides portion between the lower mould, go up the mould the lower mould with the shaping space of strake wall copper strips, the middle part of going up the mould has a plurality of running through go up the inlet opening of mould, have on the lower mould a plurality of with the corresponding apopore of inlet opening, its characterized in that be provided with the limit opening on the strake, the limit opening certainly the strake is close to one end of mould export is extended to another tip direction and is set up.
Preferably, the length of the edge hole is 2-4 times of the thickness of the edge strip.
Preferably, the side hole is a circular hole, and the axis of the side hole is parallel to the length direction of the edge strip.
Further preferably, the distance from the edge hole to the upper surface of the edge strip is 0.1-0.4 of the thickness of the edge strip, the distance from the edge hole to the lower surface of the edge strip is 0.1-0.4 of the thickness of the edge strip, and the distance from the edge hole to the forming space is 0.1-0.4 of the thickness of the edge strip.
Preferably, the inner side surface of the edge strip is an inwards concave cambered surface.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
because the utility model discloses set up the limit hole on the strake, can reduce the cooling rate of copper strips edge part for the copper strips can the secondary crystallization after leaving the mould, makes the difficult crackle that produces of edge part of copper strips.
Drawings
FIG. 1 is a perspective view of the present invention;
FIG. 2 is a front view of the present invention;
fig. 3 is a cross-sectional view a-a of fig. 2.
In the above drawings: 1. an upper die; 2. a lower die; 3. edging; 4. a molding space; 5. a water inlet hole; 6. a water outlet hole; 7. and (4) side holes.
Detailed Description
The invention will be further described with reference to the embodiments shown in the drawings to which:
referring to the attached drawings 1-3, a crystalline graphite mold for improving the edge of a copper strip comprises a plate-shaped upper mold 1, a plate-shaped lower mold 2 and two edge strips 3 positioned at two sides between the upper mold 1 and the lower mold 2, wherein the inner side surfaces of the edge strips 3 are concave cambered surfaces, the upper mold 1, the lower mold 2 and the edge strips 3 enclose a forming space 4 of the copper strip, the middle of the upper mold 1 is provided with a plurality of water inlet holes 5 penetrating through the upper mold 1, the lower mold 2 is provided with a plurality of water outlet holes 6 corresponding to the water inlet holes 5, and the crystalline graphite mold is characterized in that the edge strips 3 are provided with edge holes 7, and the edge holes 7 are arranged in a manner of extending from one end part.
In this embodiment, the edge hole 7 is a circular hole, and the length thereof is 3 times the thickness of the edge strip 3. The distance from the edge hole 7 to the upper surface of the edge strip 3, the distance from the lower surface of the edge strip 3 and the distance from the forming space 4 are all 0.3 time of the thickness of the edge strip 3.
Because this embodiment has set up limit hole 7 on strake 3, can reduce the cooling rate of copper strips edge part for the copper strips can secondary crystallization after leaving the mould, makes the edge part of copper strips be difficult for producing the crackle. Thereby saving the trimming process and solving the production cost.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
