DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figure 1 - Figure 2 , a multi-layer embossed co-extrusion profile die, including a co-extrusion profile die body 1. A feed hopper 2 fixedly connected thereto is provided at the rear end of the co-extrusion profile die body 1. The outer wall of the feed hopper 2 is provided with an external thread. The feed hopper 2 is connected to an external injection pipe, and can be used to continuously inject injection liquid. The injection liquid is formed into a pipe body within the co-extrusion profile die body 1 to obtain a required pipe body product.

[0022] An accommodation cavity 3 is provided within the co-extrusion profile die body 1. The feed hopper 2 communicates with the accommodation cavity 3. The accommodation cavity 3 accommodates the injection liquid. A forming groove 4 is formed on the co-extrusion profile die body 1. The forming groove 4 cools the injection liquid to form a pipe body. The accommodation cavity 3 communicates with the forming groove 4. The diameter of the accommodation cavity 3 is larger than that of the forming groove 4. Two connecting rods 5 are fixedly connected to the inner wall of the accommodation cavity 3. The two connecting rods 5 jointly fixedly connect a cylinder 6. The cylinder 6 is arranged within the accommodation cavity 3 and the forming groove 4. The cylinder 6 penetrates through the co-extrusion profile die body 1. The outer wall of the pipe body abuts against the inner wall of the forming groove 4, and the inner wall of the pipe body abuts against the outer wall of the cylinder 6, so that the pipe body is extruded and shaped.

[0023] A plurality of fixing plates 7 distributed at equal intervals are fixedly connected to the front end of the co-extrusion profile die body 1. An embossing mechanism is provided on each fixing plate 7. The embossing mechanism includes two T-shaped rods 8 penetrating through and slidably connected to the fixing plate 7. The two T-shaped rods 8 jointly fixedly connect a U-shaped plate 9. One end of the U-shaped plate 9 close to the fixing plate 7 is rotatably connected to a threaded rod 10. The threaded rod 10 penetrates through the fixing plate 7 and is threadedly connected thereto. A through hole is formed through the fixing plate 7. External threads and internal threads that cooperate with each other are respectively provided on the outer wall of the threaded rod 10 and the inner wall of the through hole. A handwheel 11 is fixedly connected to the end of the threaded rod 10 away from the U-shaped plate 9. An embossing wheel 12 is rotatably connected to the inner wall of the U-shaped plate 9. The outer wall of the embossing wheel 12 is provided with protruding steel patterns. The outer wall of the embossing wheel 12 abuts against the outer wall of the pipe body, realizing the embossing operation. The plurality of embossing wheels 12 provided are respectively used for steel stamping the production date, product batch number, and relevant parameter information; when the materials of the injection-molded pipe bodies are different, the hardness and stiffness of the pipe bodies are different at this time. By rotating the handwheel 11 to drive the contact force between the embossing wheel 12 and the pipe body, the steel stamping requirements for different materials are met.

[0024] A cooling mechanism is provided on each fixing plate 7. The cooling mechanism includes a motor 13 fixedly connected to one side of the fixing plate 7. The end of the output shaft of the motor 13 is fixedly connected to a fan 14. By rotating the fan 14, the injection-molded pipe body can be blown to cool it quickly, accelerating the forming of the pipe body.

[0025] In the present utility model, the injection molding liquid heated and melted is injected into the co-extruded profile die body 1 through the feed hopper 2. The injection molding liquid first fills the accommodation cavity 3, and then the injection molding liquid enters the forming groove 4 from the accommodation cavity 3 to be cooled and formed into a tube body (the diameter of the accommodation cavity 3 being larger than that of the forming groove 4 enables continuous tube body forming). When discharging the tube profile, the embossing wheel 12 is driven to rotate by contacting the outer wall of the tube profile, and the embossing steel stamp provided on the surface of the embossing wheel 12 can emboss the formed tube body (the production date, product batch number, and relevant parameter information can be embossed respectively). The motor 13 provided can drive the fan 14 to rotate, and can rapidly cool the formed tube body to enable rapid forming. The worker holds the hand wheel 11 and rotates it to drive the threaded rod 10 to rotate, causing the U-shaped plate 9, the two T-shaped rods 8, and the embossing wheel 12 to move, and adjusting the force between the embossing wheel 12 and the outer wall of the formed tube body to meet the requirements of embossing steel stamps for tube bodies of different materials (the hardness and stiffness of tube bodies of different materials are different, and the force for embossing steel stamps is different).

[0026] The present utility model can adjust the embossing force of the embossing wheel on the tube body through the embossing mechanism, solving the problem in the prior art that when the materials of the tube body products formed by injection molding are different, the hardness and stiffness of the tube bodies of different materials are different, while the embossing force of general steel stamps is the same, resulting in poor embossing effects of steel stamps on tube bodies with relatively high hardness, and deformation of tube bodies with relatively soft hardness due to excessive force.
