DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-3 A hydraulic punching machine for aluminum alloy doors and windows includes a bracket 1, an upper die 3 and a lower die 4. The inner wall of the top of the bracket 1 is fixedly connected to a cylinder 2, the piston rod end of the cylinder 2 is fixedly connected to the upper die 3, and a lower die 4 is provided below the upper die 3. Fixed blocks 5 are fixedly connected to the side walls of the upper die 3 and the lower die 4 respectively. Push rods 6 are hingedly provided on the side walls of multiple fixed blocks 5. The ends of the two push rods 6 facing away from the fixed blocks 5 are hingedly provided with connecting blocks 7 at the same time. A cavity is opened on the inner wall of the bottom end of the lower die 4, and a support column 9 is provided inside the cavity for sliding. The top of the support column 9 is fixedly connected to a top plate 10.

[0022] A guide block 8 is fixedly connected to the side wall of the connecting block 7, a guide groove is provided on the inner wall of the guide block 8, and the guide block 8 is slidably arranged inside the guide groove. The bracket 1 is fixedly connected to the inner wall of the guide groove with a buffer pad 11, and the side wall of the buffer pad 11 is in contact with the side wall of the guide block 8. The bottom side wall of the support column 9 is fixedly connected to a stabilizing seat 12, and the top of the top plate 10 is fixedly connected to a metal wear-resistant plate 13.

[0023] By extending the piston rod of the cylinder 2, the upper mold 3 can be moved downward, so that the upper fixed block 5 pushes the push rod 6 to swing, and pushes the connecting block 7 to slide along the inside of the guide groove through the guide block 8, so that the lower push rod 6 can pull the fixed block 5 to move, and the lower mold 4 can be moved upward, so that the aluminum alloy can be press-cut. The subsequent downward movement of the lower mold 4 can make the top plate 10 extend to the top of the cavity, and the press-cut aluminum alloy part can be ejected to the outside of the lower mold 4 for easy demoulding.
