A hydraulic arm 7 for pushing the upper die seat 5 up and down is installed on the top plate 4. Through this structural method, the hydraulic arm 7 is started to push the upper die seat 5 and the upper die body 6 downward, and the upper die body 6 and the two lower die bodies 3 can be used for extrusion molding of aluminum profiles. The two lower die seats 2 are driven by the driving mechanism 9 to drive the two lower die bodies 3 to separate, so that the aluminum profile can be quickly demolded. The two lower die seats 2 are driven by the driving mechanism 9 to approach each other, and the pair of lower die bodies 3 are assembled again, and the aluminum profile can be extruded again. The structure is reasonable, and the processing efficiency of the aluminum profile is improved through rapid demolding.

[0025] In a further embodiment, a plurality of insert plates 17 are provided on the outer wall of the lower mold body 3, and a slot 18 for accommodating the insert plates 17 is provided on the inner wall of the lower mold base 2. By plugging and fitting the insert plates 17 into the slots 18, the lower mold body 3 can be assisted in being positioned on the lower mold base 2, thereby alleviating the shear stress on both sides of the lower mold base 2 and the lower mold body 3. The two lower die bases 2 are provided with a limit piece 16 for limiting the lower die body 3 from separating from the lower die base 2. The limit piece 16 is a limit plug rod 20 inserted through the lower die base 2. A through hole 19 that can allow the limit plug rod 20 to pass horizontally is opened on the plug plate 17. The limit plug rod 20 is inserted into the lower die base 2 and passes through the plug plate 17, so that the lower die body 3 can be limited in the lower die base 2 to prevent the lower die body 3 from falling off. Preferably, the upper die base 5 and the upper die body 6 are also assembled in this way. With this structural method, the lower die body 3 or the upper die base 5 can be replaced by only pulling the limit plug rod 20 out of the lower die base 2. Furthermore, for aluminum profiles of different specifications and models, only the corresponding lower die body 3 and upper die base 5 need to be equipped, and there is no need to equip a complete set of equipment separately, which reduces the equipment investment cost and reduces the economic pressure on the enterprise.

A driving motor 15 for driving the bidirectional threaded column 14 to rotate is installed at the end of the base plate 1. When the driving motor 15 is started to drive the bidirectional threaded column 14 to rotate, the pair of sleeve blocks 13 can be driven to drive the two lower mold bases 2 to slide away from or close to each other along the slide groove 12 for demoulding and closing the mold.

[0028] When in use, the upper die seat 5 and the upper die body 6 are pushed downward by starting the hydraulic arm 7, and the upper die body 6 and the two lower die bodies 3 can be used for extrusion molding of aluminum profiles. By starting the drive motor 15 to drive the bidirectional screw column 14 to rotate, a pair of sleeve blocks 13 are driven to drive the two lower die seats 2 to slide away from each other along the slide groove 12, thereby separating the two lower die bodies 3, and realizing rapid demoulding of the aluminum profile. The drive motor 15 is started in the reverse direction to drive the pair of lower die seats 2 to approach each other, and the pair of lower die bodies 3 are assembled again, and the aluminum profile can be extruded again. The structure is reasonable, and the processing efficiency of the aluminum profile is improved through rapid demoulding. Furthermore, by utilizing the plug-in cooperation between the plug plate 17 and the slot 18, the lower mold body 3 can be assisted in being positioned on the lower mold base 2, thereby alleviating the shear stress on both sides of the lower mold base 2 and the lower mold body 3. By inserting the limiting plug rod 20 into the lower mold base 2 and penetrating the plug plate 17, the lower mold body 3 can be limited in the lower mold base 2 to prevent the lower mold body 3 from falling off. In addition, with this structural method, the lower mold body 3 can be replaced by simply pulling the limiting plug rod 20 out of the lower mold base 2. Furthermore, for aluminum profiles of different specifications and models, only the corresponding lower mold body 3 and upper mold base 5 need to be equipped, and there is no need to separately equip a complete set of equipment, which reduces the equipment investment cost and reduces the economic pressure on the enterprise.
