Description

Technical Field

[0001] The utility model relates to the technical field of aluminum extrusion dies, and particularly relates to a special-shaped aluminum profile extrusion die. Background Technique

[0002] When an aluminum extrusion die is in use, an aluminum ingot is first placed in a heating furnace of an extruder and heated to a certain temperature to make it fully softened. Then, the softened aluminum ingot is placed in the die of the extruder. The die usually consists of two semi-circular parts. After being tightly closed, a huge pressure is applied to the aluminum ingot, causing it to gradually flow towards the die outlet. Under the action of the pressure, the aluminum ingot flows out from the outlet of the die to form the required aluminum profile. During this process, the temperature of the aluminum profile is still very high and needs to be cooled to be shaped.

[0003] At present, when most aluminum extrusion dies are in use, both dies are subjected to extrusion, making the direct fit between the two dies relatively tight, resulting in difficulty in separating the two dies when use is completed. Therefore, it is necessary to design a special-shaped aluminum profile extrusion die that is convenient to separate the two dies after use to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a special-shaped aluminum profile extrusion die to solve the problems raised in the above background technique.

[0005] A special-shaped aluminum profile extrusion die of the utility model includes a convex die and a concave die. A plurality of shunt holes are penetrated and opened on one side of the convex die. An extrusion hole is penetrated and opened at the central position on one side of the concave die. A die core is arranged at the central position on the side of the convex die close to the concave die. A docking component is arranged on the side of the convex die close to the concave die. The docking component includes a docking rod, a first insertion rod, a cross-shaped insertion block, a grip rod, a docking hole, a cross-shaped slot, and a second insertion rod. One end of the second insertion rod is provided with a prying component. The prying component includes a prying block, a nut, a first limiting block, a movable cavity, and a second limiting block.

[0006] As a further improvement of the utility model, a second extrusion cavity and a first extrusion cavity are respectively opened on the opposite surfaces of the convex die and the concave die. A snap ring and a slot are respectively arranged at positions close to the edge on the opposite surfaces of the convex die and the concave die. The snap ring is movably clamped in the slot and their sizes are mutually compatible.

[0007] As a further improvement of the utility model, there are two docking rods, and both are arranged on the side of the convex die close to the concave die. The docking hole is penetrated and opened at the position on the concave die corresponding to the docking rod. Threads are opened on the outer surface of the docking rod far from the convex die.

[0008] As a further improvement of the present utility model, the cross-shaped insertion block and the prying block are respectively arranged at one end of the first insertion rod and the second insertion rod close to the concave mold, and the diameters of the first insertion rod and the second insertion rod are both adapted to the diameter of the docking hole.

[0009] As a further improvement of the present utility model, the grip rod is arranged at one end of the first insertion rod and the second insertion rod away from the concave mold, and the cross-shaped slot is opened at one end of the docking rod away from the convex mold and is sized to fit the cross-shaped insertion block.

[0010] As a further improvement of the present utility model, the nut is threadedly connected to the outer surface of the docking rod, the first limiting block is arranged on the outer surface of the docking rod, the movable cavity is opened inside the convex mold, the second limiting block is arranged at one end of the docking rod close to the convex mold, and one end of the docking rod is movably clamped in the movable cavity through the second limiting block.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By setting the prying block and the second insertion rod, and cooperating with the first limiting block and the second limiting block, when it is necessary to separate the convex mold and the concave mold, the two molds can be easily pried open and separated by using the prying block and the nut and applying the lever principle, so that it is more convenient and labor-saving for the staff to separate the two molds;

[0013] 2. At the same time, by using the cross-shaped slot and the cross-shaped insertion block provided, and cooperating with the first insertion rod, before prying, the docking rod can be rotated first, and a certain looseness can be generated between the convex mold and the concave mold through the rotation of the docking rod, so as to facilitate subsequent prying.

[0023] Please refer to Figures 1-3, the utility model includes a convex mold 01 and a concave mold 011. A number of shunt holes 02 are penetrated and opened on one side of the convex mold 01. An extrusion hole 021 is penetrated and opened at the central position on one side of the concave mold 011. A mold core 022 is arranged at the central position on the side of the convex mold 01 close to the concave mold 011.

The docking component includes a docking rod 03, a first insertion rod 031, a cross insertion block 032, a grip rod 033, a docking hole 034, a cross slot 035 and a second insertion rod 036; A prying component is arranged at one end of the second insertion rod 036. The prying component includes a prying block 05, a nut 051, a first limiting block 052, a movable cavity 053 and a second limiting block 054.

[0024] Please refer to Figure 1 and Figure 3 , in this embodiment, in order to better dock the convex mold 01 and the concave mold 011, a second extrusion cavity 024 and a first extrusion cavity 023 are respectively opened on the opposite surfaces of the convex mold 01 and the concave mold 011. A snap ring 041 and a card slot 04 are respectively arranged at the positions close to the edge on the opposite surfaces of the convex mold 01 and the concave mold 011. The snap ring 041 is movably clamped in the card slot 04 and their sizes match each other. When the convex mold 01 and the concave mold 011 are docked, the snap ring 041 on the convex mold 01 is docked with the card slot 04 on the concave mold 011, and then the convex mold 01 and the concave mold 011 are docked, so that the connection between the convex mold 01 and the concave mold 011 is tighter.

[0025] When aluminum extrusion forming is required, the heated aluminum is extruded from the shunt holes 02 into the first extrusion cavity 023 and the second extrusion cavity 024 through an external extrusion device. At this time, the mold core 022 has been inserted into the extrusion hole 021. Therefore, during extrusion, the heated aluminum passes through the gap between the mold core 022 and the extrusion hole 021 and is finally extruded into shape.

[0026] Please refer to Figure 1 and Figure 2 , it should be noted that, in order to better separate the convex mold 01 and the concave mold 011, there are two docking rods 03, and both are arranged on the side of the convex mold 01 close to the concave mold 011. The docking hole 034 is penetrated and opened at the position of the concave mold 011 corresponding to the docking rod 03. Threads are opened on the outer surface of the docking rod 03 away from the convex mold 01;

[0027] The cross insertion block 032 and the prying block 05 are respectively arranged at one end of the first insertion rod 031 and the second insertion rod 036 close to the concave mold 011. The diameters of the first insertion rod 031 and the second insertion rod 036 are both adapted to the diameter of the docking hole 034;

[0028] The grip rod 033 is arranged at one end of the first insertion rod 031 and the second insertion rod 036 away from the concave mold 011. The cross slot 035 is opened at one end of the docking rod 03 away from the convex mold 01 and is sized to fit the cross insert 032.

[0029] The nut 051 is threadedly connected to the outer surface of the docking rod 03. The first limiting block 052 is arranged on the outer surface of the docking rod 03. The moving cavity 053 is opened inside the convex mold 01. The second limiting block 054 is arranged at one end of the docking rod 03 close to the convex mold 01. One end of the docking rod 03 is movably clamped in the moving cavity 053 through the second limiting block 054. Both the first limiting block 052 and the second limiting block 054 are fixedly connected to the docking rod 03.

[0030] When it is necessary to separate the convex mold 01 and the concave mold 011, first put the nut 051 on the docking rod 03 and screw it in, and leave a certain gap between the nut 051 and the concave mold 011. Then hold the grip rod 033 on the first insertion rod 031 and insert the cross insert 032 into the cross slot 035 to drive the docking rod 03 to rotate, so that the convex mold 01 and the concave mold 011 are loosened a little. Then hold the second insertion rod 036 and insert the pry block 05 into the gap between the nut 051 and the concave mold 011 and pry it. Drive the docking rod 03 and the first limiting block 052 through the lever principle, and drive the concave mold 011 to move to the side away from the convex mold 01 through the first limiting block 052, so as to separate them.
