[0002] Alloy profiles are a type of material made of alloys, usually composed of two or more metal elements. Alloy profiles have excellent mechanical properties, strong corrosion resistance, high thermal strength, and are suitable for manufacturing and processing in various industrial fields. Alloy profiles are widely used in aerospace, automobile manufacturing, electronic equipment, building structures, machinery manufacturing and other fields.

[0003] Common alloy profiles include aluminum alloy profiles, steel alloy profiles, magnesium alloy profiles, etc. Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials and needs to be extruded during its processing. An extrusion molding device is required to process the aluminum alloy profile. During the extrusion process, a large force is applied to deform the alloy profile. After extrusion molding, the molded part fits tightly to the inner wall of the mold, which makes the subsequent demolding more complicated. In view of this, we proposed an alloy profile extrusion molding device. Utility Model Content

The parts are connected, and a driving assembly is arranged on the extrusion device 6. The extrusion device 6 is an existing structure and will not be described in detail here. When extrusion molding is performed, the metal part is placed inside the mold 7, and then the extrusion device 6 is used to cooperate with the mold 7 to complete the extrusion molding of the metal part. Then the extrusion device 6 rises, and when the extrusion device 6 moves, it will synchronously cooperate with the driving assembly to drive the displacement plate 10 to move. When the displacement plate 10 moves, it will synchronously drive the demolding column 11 to move. After the demolding column 11 moves, it contacts the lower surface of the push plate 8, and then the metal part is lifted up by the rising part of the push plate 8 to complete the demolding. Through the above structure, the metal part can be automatically demolded when the extrusion device 6 is naturally reset after the extrusion is completed, without the need for additional operations, thereby reducing the demolding difficulty of the metal part molding.

The lower surface of the push plate 8 is provided with a groove 23 adapted to the demoulding column 11, and the inner wall of the groove 23 is provided with a card slot 24. An L-shaped plate 25 is arranged inside the motion cavity 9, and the lower side surface of the L-shaped plate 25 slides through the lower surface of the displacement plate 10 and is fixedly connected to the bottom wall of the motion cavity 9, and the cross plate of the L-shaped plate 25 contacts the upper surface of the displacement disk 18. The upper surface of the tool 7 is provided with a bolt 26, which synchronously drives the vertical rod 13 to move when the extrusion device 6 rises, and drives the limit plate 14 to move when the vertical rod 13 moves. The limit plate 14 contacts the displacement plate 10 after moving a certain distance, and then drives the displacement plate 10 to rise, so as to cooperate with the demoulding column 11 to complete the demoulding. At the same time, when the mold 7 is replaced, the extrusion device 6 can be controlled to continue to rise to a higher height than the normal state. At this time, the displacement plate 18 will contact the L-shaped plate 25, so that the displacement plate 18 is stationary and the demoulding column 11 continues to rise to form a relative movement, thereby compressing the second spring 22, and using the relative movement to make the vertical plate 19 "descend", thereby releasing the restriction on the two blocks 16.

After the replacement is completed, the extrusion device 6 is controlled to drop slightly to cooperate with the vertical plate 19 to re-extrude the block 16, and then the push plate 8 is replaced into the inside of the mold 7 and pressed downward so that the block 16 is re-engaged in the inside of the card slot 24 to complete the replacement. Through the above structure, the connection between the demoulding column 11 and the push plate 8 can be made more convenient. Not only can the push plate 8 be pulled to reset after demoulding, but also when replacing the mold 7, the push plate 8 can be disassembled more conveniently, thereby improving the replacement efficiency.

[0026] Working principle: When extrusion molding is performed, the metal part is placed inside the mold 7, and then the extrusion device 6 is used to cooperate with the mold 7 to complete the extrusion molding of the metal part. Then the extrusion device 6 rises, and when the extrusion device 6 moves, it will synchronously cooperate with the driving component to drive the displacement plate 10 to move. When the displacement plate 10 moves, it will synchronously drive the demoulding column 11 to move.

After the limit plate 14 moves a distance, it contacts the displacement plate 10, and then drives the displacement plate 10 to rise, thereby cooperating with the demoulding column 11 to complete the demoulding. At the same time, when the mold 7 is replaced, the controllable The extrusion device 6 continues to rise to a height higher than normal. At this time, the displacement plate 18 will contact the L-shaped plate 25, so that the displacement plate 18 is stationary while the demoulding column 11 continues to rise to form a relative movement, thereby compressing the second spring 22, and using the relative movement to make the vertical plate 19 "descend", thereby releasing the restriction on the two blocks 16, and retracting the blocks 16 to the inside of the cavity 15 under the left and right of the spring 21, completing the release of the demoulding column 11 and the push plate 8, and then removing the push plate 8, and then removing the mold 7 by the bolt 26. After the replacement is completed, the extrusion device 6 is controlled to drop slightly to cooperate with the vertical plate 19 to re-extrude the block 16, and then the push plate 8 is replaced into the interior of the mold 7 and pressed downward so that the block 16 is re-stuck in the inside of the slot 24 to complete the replacement.
