[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figures 1-3 This utility model provides an extrusion molding machine for producing peach-shaped tubes, including a base plate 1. A fixed seat 2 and a fixed frame 14 are fixedly connected to both sides of the top of the base plate 1. A groove 3 is formed at the other end of the top of the base plate 1 on the same side as the fixed seat 2. A support rod 4 is slidably connected to the inner side of the groove 3. A sliding seat 5 is fixedly connected to the top of the support rod 4. An outer mold 10 is slidably connected to the inner sides of both the fixed seat 2 and the sliding seat 5. The outer mold 10 includes locking blocks 11 that penetrate through both ends of the fixed seat 2 and the sliding seat 5. The sides of the fixed seat 2 and the sliding seat 5 away from each other are rotatably connected to... The threaded rod 12 is threadedly connected to the outer side of the sliding plate 13. Both sides of the bottom of the sliding plate 13 are fixedly connected to the clamping rods. The clamping rods are slidably connected to the inner side of the corresponding clamping block 11. The inner side of the fixing frame 14 is rotatably connected to the inner threaded sleeve 15. The inner side of the inner threaded sleeve 15 is threadedly connected to the drive rod 16. The end of the drive rod 16 near the fixing seat 2 is rotatably connected to the mounting plate 18. Its bottom end is slidably connected to the inner side of the base plate 1. The end of the mounting plate 18 near the fixing seat 2 is bolted to the inner mold 19. The outer side of the inner mold 19 and the two outer molds 10 form a compression cavity.

[0024] The outer mold 10 is installed inside the fixed seat 2 and the sliding seat 5 by the locking block 11. The threaded rod 12 is rotated so that the sliding plate 13 drives the locking rod to descend and embed into the locking block 11, thus fixing the outer mold 10. The inner mold 19 is bolted to the outside of the mounting plate 18. The steel pipe raw material is placed inside the outer mold 10 inside the fixed seat 2. The second motor is started, and the drive gear at its output end meshes with the gear ring 17, driving the inner threaded sleeve 15 to rotate, which in turn pushes the drive rod 16 and the inner mold 19 to move towards the fixed seat 2 until they move into the steel pipe.

[0025] The outer mold 10 can be quickly positioned and installed on the equipment via the locking block 11. This design not only simplifies the installation process but also ensures the stability of the outer mold 10 after installation. Rotating the threaded rod 12 can drive the moving plate 13 to rise and fall, so that the moving plate 13 drives the locking rod to fix and unlock the locking block 11. This not only enables the rapid installation and disassembly of the outer mold 10, greatly shortening the mold change time of the equipment and improving the utilization rate and production efficiency of the equipment, but also ensures the stability of the outer mold 10 during the production process through the close cooperation of the mechanical structure.

[0026] Please see Figures 1-3 Fixed blocks 6 are fixedly connected to both ends of the top and bottom of the fixed base 2 and the sliding base 5. Left frame 7 and right frame 8 are fixedly connected to both ends of the top of the base plate 1 on one side of the sliding base 5, respectively. The left frame 7 includes sliding rods fixedly connected to both ends near the sliding base 5. Fixed blocks 6 on the outer sides of the fixed base 2 and the sliding base 5, on the same side as the sliding rods, are slidably connected to the outer sides of the corresponding sliding rods. A lead screw 9 is rotatably connected to the bottom end of the right frame 8. A thread adapted to the lead screw 9 is opened on the inner side of the fixed block 6 near the lead screw 9 at the bottom of the sliding base 5, and the thread is connected to… A top rod is fixedly connected to the top of the right frame 8 on the outside of the lead screw 9. The fixed block 6 on the top of the fixed seat 2 and the sliding seat 5 near the top rod is slidably connected to the outside of the top rod. The fixed block 6 at the bottom of the sliding seat 5 near the lead screw 9 is sleeved on the outside of the lead screw 9. Motor No. 1 is fixedly connected to the outside of the right frame 8, and its output end is fixedly connected to the lead screw 9. Gear ring 17 is fixedly connected to the outside of the inner thread sleeve 15. Motor No. 2 is fixedly connected to the outside of the fixed frame 14, and a drive gear is fixedly connected to its output end. The drive gear meshes with gear ring 17.

[0027] Start motor 1 to drive screw 9 to rotate, push moving seat 5 along slide 3 to move it close to and fit against fixed seat 2, extruding the steel pipe into a peach shape. Then remove moving seat 5 and inner mold 19 to complete the extrusion.

[0028] The left frame 7 and the right frame 8 provide stable support and guidance for the shift seat 5 and the fixed seat 2, ensuring that the shift seat 5 always stays on a fixed track during the movement process, avoiding deviation of the shift seat 5 from the predetermined trajectory due to external forces or improper operation, thereby ensuring the stability of the production process.

[0029] The working principle and usage process of this utility model are as follows: The outer mold 10 is installed inside the fixed seat 2 and the sliding seat 5 by the locking block 11. The threaded rod 12 is rotated so that the sliding plate 13 drives the locking rod to descend and embed into the locking block 11, thus fixing the outer mold 10. The inner mold 19 is bolted to the outside of the mounting plate 18. The steel pipe raw material is placed inside the outer mold 10 inside the fixed seat 2. The second motor is started, and the drive gear at its output end meshes with the gear ring 17, driving the inner threaded sleeve 15 to rotate, which pushes the drive rod 16 and the inner mold 19 to move towards the fixed seat 2 until they move into the steel pipe. The first motor is started, driving the lead screw 9 to rotate, pushing the sliding seat 5 to move along the slide groove 3, so that it approaches and fits the fixed seat 2, extruding the steel pipe into a peach shape. Then the sliding seat 5 and the inner mold 19 are removed to complete the extrusion.
