Description

Novel aluminum profile extrusion die spigot structure

Technical Field

The utility model mainly relates to the field of aluminum profile extrusion dies, in particular to a novel aluminum profile extrusion die spigot structure.

Background

Because the working environment of the extrusion die is severe, the service life is short (each set of die can process about 12 tons of aluminum materials), and the die material H13 belongs to a material with higher price in die steel, so that the die cost occupies a larger proportion in the production of aluminum profiles, and the current research directions of various large die factories are to reduce the die cost, save raw materials and improve the die service life.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model provides a novel aluminum profile extrusion die spigot structure which is simple in structure, convenient to use, convenient to install and disassemble, capable of saving the physical labor of operators, reducing the die production cost, saving the processing raw materials, prolonging the service life of the die and bringing convenience to use.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

the utility model provides a novel aluminium alloy extrusion die tang structure, wraps mould and lower mould, be equipped with the reposition of redundant personnel hole on going up the mould, reposition of redundant personnel hole below is equipped with the mold core, the mold core is connected with last mould through reposition of redundant personnel bridge, be equipped with the welding chamber on the lower mould, it is equipped with the annular arch to go up mould one side, lower mould one side is equipped with the arc recess, the annular arch can be gone into the interior cooperation tang that forms of annular recess into.

Furthermore, threaded holes are formed in one sides of the bottoms of the upper die and the lower die, and the lower portion of the upper die and the lower die are connected through bolts.

Furthermore, key grooves are formed in the upper portions of the upper die and the lower die, and pins are inserted into the key grooves.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model has simple structure, convenient use and convenient installation and disassembly, saves the physical labor of operators, reduces the production cost of the die, saves the processing raw materials, prolongs the service life of the die and brings convenience to the use.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of a portion I of FIG. 1;

reference numerals shown in the drawings: 1. an upper die; 2. a lower die; 3. a shunt hole; 4. a mold core; 5. a welding chamber; 6. matching the spigot; 7. a threaded hole; 8. a bolt; 9. a pin.

Detailed Description

The utility model is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

As shown in fig. 1-2, the novel aluminum profile extrusion mold spigot structure provided by the utility model comprises an upper mold 1 and a lower mold 2, wherein a shunting hole 3 is formed in the upper mold 1, a mold core 4 is arranged below the shunting hole 3, the mold core 4 is used for forming the shape and size of an inner cavity of a profile, the mold core 4 is connected with the upper mold 1 through a shunting bridge, a welding chamber 5 is arranged on the lower mold 2, metals flowing out from the shunting hole 3 are gathered together by the welding chamber 5 and are welded together again to form an integral blank with the mold core 4 as the center, an annular protrusion is arranged on one side of the upper mold 2, an arc-shaped groove is arranged on one side of the lower mold 2, and the annular protrusion can be clamped into the annular groove to form a matching spigot 6.

Specifically, threaded holes 7 are formed in one sides of the bottoms of the upper die 1 and the lower die 2, and the lower portions of the upper die 1 and the lower die 2 are connected through bolts 8. Go up mould 1 and 2 lower parts of lower mould and pass through bolt 8 and be connected, be convenient for go up the connection of mould 1 and lower mould 2.

Specifically, key grooves are formed in the upper portions of the upper die 1 and the lower die 2, and pins 9 are inserted into the key grooves. The pin 9 has a limiting effect on the upper die 1 and the lower die 2, and can prevent the upper die 1 and the lower die 2 from sliding.

Example (b):

when the device is used, one end of a pin 9 is inserted into a key groove on the lower die 2, the upper die 1 and the lower die 2 are combined, the other end of the pin 9 is inserted into the key groove on one side of the upper die 1, an annular bulge on the upper die 1 is clamped into an annular groove on the lower die 2 to form a matching spigot 6, then the upper die 1 and the lower die 2 are fastened through a screw 7, and then aluminum is poured into the combined die for casting.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
