[0002] A pressure processing method that uses a punch or a punch to pressurize the blank placed in the die to produce plastic flow, thereby obtaining a product corresponding to the die hole or the shape of the concave and convex molds. During extrusion, the blank produces three-dimensional compressive stress. Even the blank with low plasticity can be extruded. Extrusion, especially cold extrusion, has high material utilization, improved material organization and mechanical properties, simple operation, high productivity, and can produce long rods, deep holes, thin walls, and special-shaped cross-section parts. It is an important non-cutting processing technology. Extrusion is mainly used for metal forming, and can also be used for non-metal forming such as plastics, rubber, graphite and clay blanks.

[0003] After searching, a Chinese patent discloses a non-ferrous metal alloy continuous extrusion die (publication number CN216729094U). When the punch or die needs to be replaced, the patented technology only needs to turn the hand wheel on the corresponding mounting seat, and the mutual engagement of the two bevel gears can be used to drive the first bidirectional screw and the second bidirectional screw to rotate simultaneously, and then the movable plate drives the locking rod to move so that the locking rod is disengaged from the corresponding locking groove. At this time, the punch or die can be removed. The operation is simple and quick, but when disassembling it, more complicated operating steps are required to complete the installation and disassembly, which makes the process of replacing the mold complicated and inefficient. Therefore, the technical personnel in this field provide a non-ferrous metal alloy continuous extrusion die to solve the problems raised in the above background technology. Utility Model Content

When the lower mold 102 needs to be replaced or replaced by installing the replacement mechanism 3, it can be quickly replaced by the quick-release component 32, and the lower mold 102 can be quickly installed by vacuum adsorption during installation, eliminating complicated operations during installation and disassembly. When placing the lower mold 102, the buffer component 33 can be used to buffer the placement of the lower mold 102 to reduce damage to the lower mold 102.

[0021] The quick-release assembly 32 includes a movable groove 321 opened at the bottom of the lower mold 102, and a vacuum pump 326 is fixedly installed at the bottom of the processing table 1. A first connecting pipe 323 is fixedly installed at the output end of the vacuum pump 326. One end of the first connecting pipe 323 extends to the inside of the installation groove 31 and is fixedly connected to a piston plate 322. The piston plate 322 is located inside the movable groove 321. When installing the lower mold 102, the lower mold 102 can be placed inside the installation groove 31 so that the movable groove 321 is located above the piston plate 322. The piston plate 322 is then moved to the inside of the movable groove 321, and the vacuum pump 326 is started synchronously to evacuate the movable groove 321 above the piston plate 322. The lower mold 102 can be quickly and stably fixed on the processing table 1 for installation by vacuum adsorption, which is very convenient.

[0022] The quick-release assembly 32 also includes a second connecting pipe 324 fixedly installed on one side of the piston plate 322, and the other end of the second connecting pipe 324 extends to the bottom of the processing table 1. A control valve 325 is fixedly installed on the surface of the second connecting pipe 324. The control valve 325 is opened when the lower mold 102 is installed, and the control valve 325 is closed before the vacuum pump 326 is started. When the lower mold 102 needs to be removed, the control valve 325 can be opened again, so that the movable groove 321 above the piston plate 322 can be quickly connected to the outside, so that the lower mold 102 can be easily disassembled, which is very convenient.

[0023] The edge of the mounting groove 31 is set to be inclined, and the first connecting tube 323 and the second connecting tube 324 are both connected to the inside of the movable groove 321. The mounting groove 31 with the inclined edge can be used to guide the lower mold 102 when it is placed, so that the lower mold 102 can be stably moved into the mounting groove 31.

[0024] The buffer assembly 33 includes a plurality of contact rods 331 slidably mounted on one side of the piston plate 322, one end of the plurality of contact rods 331 extends to the bottom of the processing table 1, and a spring 332 is sleeved through the outer sides of the plurality of contact rods 331, and the other end of the spring 332 is fixedly connected to the bottom of the processing table 1, and the plurality of contact rods 331 are sealed and slidably connected to the piston plate 322.

At the same time, the plurality of contact rods 331 can contact the inner top wall of the movable groove 321, and then the movable groove 321 squeezes the plurality of contact rods 331 downward, and the lower mold 102 is buffered by the deformation of the spring 332. When disassembling, when external gas enters the inside of the movable groove 321 above the piston plate 322, the spring 332 can assist in disassembling the lower mold 102 by resetting the contact rods 331.

[0025] One end of the contact rod 331 is located above the piston plate 322, and the contact rod 331 contacts the top wall of the movable groove 321. Multiple contact rods 331 are evenly distributed at the four corners of the piston plate 322. The contact rods 331 evenly distributed at the four corners are reset by the corresponding springs 332. When the lower mold 102 is lifted, the lifting force can be more uniform.

[0026] Working principle: When installing the lower mold 102, the lower mold 102 can be placed in the installation groove 31 so that the movable groove 321 is located above the piston plate 322, and then the piston plate 322 is moved to the inside of the movable groove 321, and the vacuum pump 326 is started synchronously to evacuate the movable groove 321 above the piston plate 322. The lower mold 102 can be quickly and stably fixed on the processing table 1 by vacuum adsorption to achieve installation, which is very convenient. When installing the lower mold 102, the control valve 325 is opened, and before the vacuum pump 326 is started, the control valve 325 is closed. When the lower mold 102 needs to be removed, the control valve 325 can be opened again, and the piston plate 322 can be quickly and stably fixed on the processing table 1. The upper movable groove 321 is connected to the outside, so the lower mold 102 can be disassembled conveniently. The multiple contact rods 331 are sealed and slidably connected to the piston plate 322. The multiple contact rods 331 can be moved to the inside of the movable groove 321 on the piston plate 322. At the same time, the multiple contact rods 331 contact the top wall of the movable groove 321, and then the movable groove 321 squeezes the multiple contact rods 331 to move downward. The lower mold 102 is buffered by the deformation of the spring 332. When disassembling, when external gas enters the movable groove 321 above the piston plate 322, the spring 332 can reset the contact rods 331 to assist the disassembly of the lower mold 102.
