[0027] After the aluminum profile workpiece is formed in the forming groove of the lower die 2, the electric push rod 12 moves downward to drive the push plate 18 to move downward through the push rod 16, and the push plate 18 moves downward while being slidingly connected to the inclined surface structure of the connecting rod 14 through the cooperation of the inclined surface structures, so that the connecting rod 14 can better push the abutting plate 15 to move outward of the upper die 3, the abutting plate 15 is in contact with the formed piece and moves upward following the movement of the upper die 3, and the subsequent blanking work is facilitated.

[0028] With reference to Figure 1 and Figure 2 , the top of the base 1 and on one side of the lower die 2 are provided with a blanking assembly, the blanking assembly comprises a blanking plate 7 movably connected between the lower die 2 and the upper die 3, an electric motor 5 fixedly connected to the top of the base 1, and a connecting plate 6 fixedly connected to the output shaft of the electric motor 5, wherein the connecting plate 6 is fixedly connected to the blanking plate 7, the movement of the blanking plate 7 is driven by the rotation of the electric motor 5, and the automatic blanking of the aluminum profile is realized. One side of the base 1 is provided with a collection box 8 for collecting the blanked aluminum profile, and an L-shaped stop rod 9 is fixedly connected to the top of the collection box 8 and away from the electric motor 5, the stop rod 9 is located above the blanking plate 7, and the stop rod 9 is used for the aluminum profile on the blanking plate 7 to fall into the collection box 8 when blanking.

[0029] After the electric motor 5 drives the blanking plate 7 to move to the bottom of the upper die 3, the formed piece on the upper die 3 falls above the blanking plate 7, the reverse rotation of the electric motor 5 drives the blanking plate 7 and the formed piece thereon to move above the collection box 8, and when the blanking plate 7 continuously moves below the stop rod 9, the formed piece can fall into the collection box 8 under the action of the stop rod 9 to complete the blanking work, and the blanking work is simple and efficient.

[0030] With reference to Figure 4, the ejection assembly comprises a movable plate 20 slidably connected to the inside of the lower die 2, a ejector rod 19 slidably connected to the inside of the lower die 2 and fixedly connected with the movable plate 20, and a spring 13 sleeved outside the ejector rod 19 and located at the bottom of the movable plate 20, for resetting the ejector rod 19 and the movable plate 20 after the aluminum profile is ejected.

[0031] When the aluminum profile is extruded in the forming groove of the lower die 2, the ejector rod 19 is pushed to move downward so that the top of the ejector rod 19 is flush with the bottom wall of the forming groove, so as to better perform the forming work. After the forming is completed, the upper die 3 is separated from the lower die 2, and the ejector rod 19 is reset under the action of the spring 13, so that the formed part can be better ejected, so that the formed part is separated from the forming groove, and the moving lifting following the movement of the upper die 3 is facilitated.

[0032] Referring to Figure 1 and Figure 2 , the top of the base 1 and one side of the lower die 2 are fixedly connected with an L-shaped fixed frame 4, the top of the fixed frame 4 is fixedly connected with an air cylinder 10, the piston rod of the air cylinder 10 is fixedly connected with the upper die 3, and the air cylinder 10 is used to drive the upper die 3 to move up and down. The top of the upper die 3 is fixedly connected with two guide rods 11 symmetrically, the guide rods 11 are slidably connected with the fixed frame 4, and the guide rods 11 are used to increase the stability of the upper die 3 when moving up and down.

[0033] Working principle: when the aluminum profile is extruded in the forming groove of the lower die 2, the ejector rod 19 is pushed to move downward so that the top of the ejector rod 19 is flush with the bottom wall of the forming groove, so as to perform the extrusion forming work;

[0034] After the aluminum profile workpiece is formed in the forming groove of the lower die 2, the electric push rod 12 moves downward to drive the push plate 18 to move downward through the push rod 16. The push plate 18 moves downward while being slidably connected with the inclined surface structure of the connecting rod 14 through the inclined surface structure, so as to better push the abutting plate 15 to move outward of the upper die 3 through the connecting rod 14. The abutting plate 15 contacts the formed part and moves upward following the movement of the upper die 3, so as to facilitate the subsequent blanking work.

[0035] When the blanking of the formed part needs to be performed, the motor 5 operates to drive the blanking plate 7 to move to the bottom of the upper die 3. The electric push rod 12 drives the push rod 16 to move upward so that the push plate 18 moves upward and separates from the connecting rod 14. The abutting plate 15 does not apply a pushing force to the formed part, which is beneficial to the separation of the formed part from the upper die 3 and the completion of the falling operation. The formed part falls above the blanking plate 7, and the reverse rotation of the motor 5 drives the blanking plate 7 and the formed part thereon to move above the collecting box 8. When the blanking plate 7 continuously moves below the stop rod 9, the formed part can fall into the collecting box 8 under the action of the stop rod 9 to complete the blanking work. The blanking work is simple and efficient, realizes the automatic blanking and collection after the extrusion forming of the aluminum profile, and is beneficial to improving the production efficiency.
