[0031] Further, the opening and closing mechanism 4 includes two pairs of door panels 41. The back sides of the pair of door panels 41 are hinged to the bottom of the feeding chamber 2. Hinge seats 42 are fixed on the bottom surfaces of the two pairs of door panels 41. A first connecting rod 43 and a second connecting rod 44 are respectively hinged to the hinge seats 42.

At this time, the main hinge rod 62 is in the maximum open state. Then, the second telescopic cylinder 65 on the clamping mechanism 6 drives the secondary hinge rod 63 to contract inward, so that the main hinge rod 62 clamps both ends of the aluminum rod. The third rotating motor 523 drives the rotating gear 522 to rotate and move along the rack 521, and then the sliding block 53 slides on the track 51 to below the feeding chamber 2. At this time, the double-leaf door panel 41 of the opening and closing mechanism 4 is in the open state. The first telescopic cylinder 532 drives the clamping mechanism 6 to rise to the fixing mechanism 3. The third telescopic cylinder 31 drives the fixing block 32 to fix the aluminum rod. The first rotating motor 47 rotates to make the third connecting rod 46 rotate clockwise, and then drives the mutually hinged first connecting rod 43 and second connecting rod 44 to pull down to close the double-leaf door panel 41. Repeat the above operations to send the aluminum rod into the remaining feeding chambers 2, and start processing the aluminum rod. The pushing telescopic cylinder 11 pushes the aluminum rod to the mold for processing and then pushes it out from the discharge port 12; when the infrared sensor senses that the aluminum rod in the feeding chamber 2 has been processed, the conveying mechanism 5 feeds the material again into the feeding chamber 2 to achieve automatic continuous feeding.

[0038] The above are only the preferred embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.
