[0024] The molding mechanism 1 includes a mounting frame 101. A hydraulic cylinder 102 is fixed to the top of the mounting frame 101. One end of the hydraulic cylinder 102 passes through the mounting frame 101 and is fixed to an upper mold head 103. An extension plate 104 is fixed to the middle of the surface of the mounting frame 101. An installation groove is opened on the surface of the extension plate 104. A lower mold base 105 is fixed to the inner wall of the installation groove. An installation plate 106 is provided below the extension plate 104 and is fixed to the surface of the mounting frame 101. An ejection cylinder 107 is fixed to the bottom of the installation plate 106. One end of the ejection cylinder 107 passes through the installation plate 106 and is fixed to an ejection block 108. An ejection groove is opened at the bottom of the lower mold base 105. The ejection block 108 is located in the ejection groove. A feeding structure is provided on the top left side of the extension plate 104.

[0025] Through the above technical solution, the mounting frame 101 provides rigid support for the whole, the hydraulic cylinder 102 extends vertically downward, driving the upper die head 103 to perform cold extrusion on the blank in the lower die base 105, the extension plate 104 separates the forming area and the ejection area into upper and lower layers, the ejection cylinder 107 drives the ejection block 108 to push the finished product from bottom to top along the ejection groove, and the feeding structure completes automatic material dropping on the left side; this structure integrates extrusion, ejection and feeding into the same vertical space, shortens the force transmission chain, reduces energy loss, ensures good mold centering, the ejection block 108 is hidden in the ejection groove and does not occupy external space, avoids collisions, and the feeding structure moves synchronously with the forming to reduce waiting time, thereby improving efficiency and reducing the risk of manual intervention.

[0026] The feeding structure on the top left side of the extension plate 104 includes an electric cylinder 109, which is fixed to the top of the extension plate 104. A connecting plate 110 is fixed to one end of the electric cylinder 109. A feeding pipe 111 is fixed to the surface of the connecting plate 110. A push half-pipe 112 is fixed to the right side surface of the feeding pipe 111. A connecting frame 113 is fixed to the right side surface of the extension plate 104. Two combination grooves are opened on the surface of the connecting frame 113. A connecting slide plate 115 is slidably connected to the surface of the combination grooves. A collection box 114 is fixed between the front and rear connecting slide plates 115.

[0027] Through the above technical solution, the electric cylinder 109 provides linear reciprocating power, the connecting plate 110 transmits the thrust of the electric cylinder 109 to the feeding pipe 111, the feeding pipe 111 and the pushing half pipe 112 form a semi-enclosed channel to ensure that the billet will not roll off during horizontal transfer, the connecting frame 113 and the combined groove provide sliding guidance for the collection box 114, and the connecting slide plate 115 allows the collection box 114 to be quickly disassembled and assembled.

[0028] Two pins 116 are provided above the connecting frame 113, and positioning holes for the pins 116 to pass through are provided on the surfaces of both the connecting frame 113 and the connecting slide plate 115.

[0029] Through the above technical solution, the pin 116 passes through the positioning hole of the connecting frame 113 and the connecting slide plate 115 to form a mechanical lock that can be repeatedly inserted and removed. When it is necessary to transfer the finished product, the collection box 114 can be released by pulling out the pin 116, and it can be locked by inserting it when reinstalling.

Multiple connecting frames 203 are fixed on the surface of the conveyor 202, and guide frames 204 are fixed on the surface of the connecting frames 203.

[0033] Through the above technical solution, the support table 201 carries the conveyor 202, and the conveyor 202 uses continuous cyclic motion to transport batches of billets forward in sequence. The connecting frame 203 suspends the guide frame 204 above the conveyor 202. The guide frame 204 prevents the billets from tipping over and guides the billets to the rotary feeding mechanism 3.

[0034] The rotary feeding mechanism 3 includes a connecting seat 301, which is fixed to the surface of the conveyor 202. A semi-circular plate 302 is fixed to the top of the connecting seat 301. An arc-shaped frame 303 is fixed to the top of the semi-circular plate 302. An extension frame 304 is fixed to the top of the arc-shaped frame 303. A drive motor 305 is fixed to the top of the extension frame 304. The output shaft of the drive motor 305 passes through the extension frame 304 and is fixed to a rotating shaft 306. Two rotating plates 307 are fixed to the surface of the rotating shaft 306. Multiple loading slots for feeding blanks are opened on the surface of the rotating plates 307.

[0035] Through the above technical solution, the connecting seat 301 fixes the semi-circular plate 302 to the end of the conveyor 202, the arc frame 303 and the extension frame 304 form a cantilever support, the drive motor 305 drives the rotating plate 307 to rotate intermittently through the rotating shaft 306, the loading trough receives the blanks sent by the conveyor 202 one by one, and when rotating to the lowest point, the blanks are sent into the guide pipe 308 by gravity; this mechanism converts continuous conveying into intermittent feeding, the number of loading troughs is matched with the rotation angle, ensuring that only one blank is released per cycle, avoiding stacking and blockage.

[0036] A guide tube 308 is fixed at the bottom of the semi-circular plate 302, and the guide tube 308 is located above the feeding tube 111.

[0037] Through the above technical solution, the upper end of the guide tube 308 receives the semi-circular plate 302, and the lower end is aligned with the feeding tube 111. The internal channel is smooth, and gravity and lateral limiting are used to keep the axis of the billet always consistent with the center line of the feeding tube 111.

[0038] Working principle: The entire production line is centered around the forming mechanism 1. The conveying mechanism 2 continuously feeds batches of blanks to the rotary feeding mechanism 3. The rotating plate 307 of the rotary feeding mechanism 3 rotates intermittently under the control of the drive motor 305. With each rotation, a blank falls through the guide tube 308 into the feeding tube 111. The electric cylinder 109 then pushes the feeding tube 111 forward, allowing the blank to fall precisely into the lower die base 105. Subsequently, the electric cylinder 109 resets, and the hydraulic cylinder 102 drives the upper die head 103 downward to complete the cold extrusion. The ejector cylinder 107 drives the ejector block 108. The finished product is ejected from the mold cavity, and the electric cylinder 109 extends again, pushing the half-tube 112 into the collection box 114 with the help of the inclined guide plate 119. The pin 116 locks the collection box 114 to ensure stable transportation. When the box is full, the pin 116 can be pulled out for overall transfer. The entire line cycle is uniformly scheduled by the control unit. The actions of conveying, rotating, forming, ejecting and collecting are interlocked to achieve automatic cycle. The entire process does not require manual entry into dangerous areas and can be operated continuously, avoiding the risks of crushing, burning and scratching caused by traditional manual feeding and unloading.
