[0027] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited do not limit the present invention.

[0028] Referring to Figures 1-2 shown, this embodiment discloses a special-shaped profile composite extrusion forming device, including a discontinuous forming component 3 and a continuous forming component 4; the discontinuous forming component 3 is used for forming non-continuous parts on the product, and the continuous forming component 4 is used for forming continuous parts on the product;

[0029] The discontinuous forming assembly 3 includes a transmission chain 33 which is driven to rotate by a driving device. The transmission chain 33 includes a plurality of sequentially connected link members 331. Adjacent two link members 331 are hinged by a pin shaft so that relative swinging can occur between the two link members 331. Each link member 331 is provided with a first forming groove 3311, and a second forming groove 3312 is provided on the inner wall of the first forming groove 3311; the second forming groove 3312 is used for forming discontinuous components on the product;

[0030] The continuous forming assembly 4 includes a core 41 and a mold base 43. The core 41 is provided with a plug-in portion 411 and a continuous forming portion 412. The plug-in portion 411 is plugged into the first forming groove 3311 of some link members 331, that is, the plug-in portion 411 is only plugged into the first forming grooves 3311 of a plurality of link members 331 (not all link members) moving to the side of the core 41. The shapes of the plug-in portion 411 and the first forming groove 3311 are adapted to each other. The continuous forming portion 412 is connected to the mold base 43. A continuous forming cavity 413 is formed between the continuous forming portion 412 and the mold base 43. The outlet of the continuous forming cavity 413 is communicated with the outside, so that the raw material in the continuous forming cavity 413 can flow into the second forming groove 3312 through the outlet of the continuous forming cavity 413, that is, the continuous forming cavity 413 is communicated with the corresponding second forming groove 3312. Refer to Figure 2 , the raw material ejected by the raw material injector 44 can flow into one of the second forming grooves 3312 on its right through the outlet of the continuous forming cavity 413.

[0031] The mold base 43 is also connected with a raw material injector 44. The discharge port of the raw material injector 44 is communicated with the continuous forming cavity 413. Raw material is injected into the continuous forming cavity 413 through the discharge port of the raw material injector 44. The raw material can flow out of the continuous forming cavity 413 to the second forming groove 3312. The raw material flowing out to the second forming groove 3312 forms discontinuous components on the product, while the raw material that directly outputs through the continuous forming cavity 413 without flowing to the second forming groove 3312 during the movement of the transmission chain 33 is shaped to form continuous components on the product.

[0032] With the above structure, through the cooperation of the discontinuous forming assembly 3 and the continuous forming assembly 4, the composite forming of continuous and discontinuous components on the product can be effectively carried out, one-time forming can be achieved, and secondary processing positioning is avoided.

[0033] In one embodiment, the driving device includes a first driving wheel 31 and a second driving wheel 32. The first driving wheel 31 and the second driving wheel 32 are connected by a transmission chain 33 to drive the transmission chain 33 to transmit through the rotation of the first driving wheel 31 and the second driving wheel 32.

[0034] In one embodiment, the shapes of the first driving wheel 31 and the second driving wheel 32 are both polygonal to better drive the transmission chain 33 to move and maintain good driving force.

[0035] Furthermore, the shapes of the first driving wheel 31 and the second driving wheel 32 are both regular polygons.

[0036] Preferably, the side length of the regular polygon is equal to the length of the link member 331 to ensure the smooth driving of the transmission chain 33.

[0037] In one embodiment, a third forming groove 4121 is provided on the continuous forming portion 412, and a forming protrusion 431 is provided on the die base 43. The shape of the forming protrusion 431 is adapted to the third forming groove 4121. The forming protrusion 431 is inserted into the third forming groove 4121, and a gap is left between the forming protrusion 431 and the third forming groove 4121 to form a continuous forming cavity 413, so as to form continuous components on the product through the continuous forming cavity 413.

[0038] In one embodiment, a blocking portion 42 is connected in the third forming groove 4121. The length of the blocking portion 42 is less than the length of the third forming groove 4121. The shape of the blocking portion 42 is adapted to the forming protrusion 431. One end of the forming protrusion 431 is inserted into the blocking portion 42 and fixed by a bolt 45, and the other end extends out of the blocking portion 42 and extends to the end of the third forming groove 4121 so that a continuous forming cavity 413 as shown in Figure 3 is formed between the forming protrusion 431 at this end and the third forming groove 4121.

[0039] The above-mentioned blocking portion 42 functions to prevent the raw material in the continuous forming cavity 413 from flowing back. At the same time, since the blocking portion 42 has a certain thickness and the length of the blocking portion 42 is less than the length of the third forming groove 4121, then connecting one end of the forming protrusion 431 to the blocking portion 42 and the other end extending out of the blocking portion 42 and extending towards the end of the third forming groove 4121 will naturally cause a gap to be formed between a section of the forming protrusion 431 extending out of the blocking portion 42 and the third forming groove 4121, and this gap directly constitutes the continuous forming cavity 413.

[0040] In one embodiment, the length of the forming protrusion 431 is the same as the length of the third forming groove 4121.

[0041] In one embodiment, the third forming groove 4121 extends from one end of the core 41 to the other end so as to penetrate the entire core 41.

[0042] In one embodiment, the mold base 43 includes a vertical plate 432, and a bottom plate 433 is connected to the bottom of the vertical plate 432 to enhance the stability of the mold base 43. The forming protrusion 431 is provided on the vertical plate 432.

[0043] In one embodiment, an installation opening 4321 is provided on the vertical plate 432. The raw material injector 44 includes a material injection nozzle 441, and the material injection nozzle 441 is connected in the installation opening. The outlet of the material injection nozzle 441 is a material outlet, and raw materials are injected into the continuous forming cavity 413 through this material outlet.

[0044] In one embodiment, the profiled bar 5 composite extrusion forming device further includes a rotating feeding member 2. A flexible member 1 is wound around the rotating feeding member 2. The output end of the flexible member 1 passes through the first forming groove 3311 of some link members 331, and the flexible member 1 is located between the first forming groove 3311 and the insertion portion 411. By rotating the rotating feeding member 2, the flexible member 1 can continuously output. Eventually, the product formed by the cooperation of the raw material injector 44 injecting raw materials through the discontinuous forming assembly 3 and the continuous forming assembly 4 is attached to the flexible member 1 to form the final finished product.

[0045] In one embodiment, the core 41 is detachably connected to the mold base 43.

[0046] Further, the core 41 and the mold base 43 are connected by bolts 45, with reliable connection and convenient disassembly.

[0047] In one embodiment, the shape of the first forming groove 3311 can be arc-shaped or parabolic, but is not limited to the above shapes, and can also be other special-shaped shapes, and its specific shape can be designed according to actual needs.

[0048] In one embodiment, refer to Figures 4-7 , the profiled bar 5 includes a flexible member 1 and a frame body 52. The frame body 52 includes an arc-shaped bottom plate 521. A plurality of ring bodies 522 are connected to the arc-shaped bottom plate 521. The arc-shaped bottom plate 521 is a continuous component, while the plurality of ring bodies 522 are spaced apart and belong to discontinuous components. The above-mentioned ring bodies 522 are parabola-shaped, and the flexible member 1 is connected inside each ring body 522.

[0049] Taking Figure 4 the profiled bar 5 shown as an example to specifically illustrate the usage method of the profiled bar composite extrusion forming device of the above embodiment:

[0050] Refer to Figures 1-2, first insert the output end of the flexible member 1 into the first forming groove 3311 of one or several link members 331 on one side of the continuous forming assembly 4, then insert the core 41 into the first forming groove 3311 where the flexible member 1 is located, and use the insertion portion 411 of the core 41 to abut against the flexible member 1 until the flexible member 1 is tightly fitted in the first forming groove 3311, that is, the flexible member 1 is located between the core 41 and the first forming groove 3311. At this time, the flexible member 1 pressed in the first forming groove 3311 will change into the same shape as the first forming groove 3311; then start the whole device for forming processing;

[0051] Drive the first driving wheel 31 and the second driving wheel 32 to rotate, so that the transmission chain 33 starts to move, and start the raw material injector 44 to inject raw materials into the continuous forming cavity 413 of the continuous forming assembly 4. The core 41 and the mold base 43 always remain stationary, while the transmission chain 33 continues to move; during the movement of the transmission chain 33, part of the raw materials entering the continuous forming cavity 413 through the discharge port of the raw material injector 44 flows to the right into a second forming groove 3312 near the continuous forming cavity 413, thus forming a non-continuous part - the ring body 522, and the other part of the raw materials in the continuous forming cavity 413 are continuously taken out during the movement of the transmission chain 33 to form a continuous part - the arc-shaped bottom plate 521. This part of the raw materials does not enter the second forming groove 3312, and the shape of the arc-shaped bottom plate 521 is the same as that of the continuous forming cavity 413; with the continuous movement of the transmission chain 33, the length of the arc-shaped bottom plate 521 continuously increases, and multiple spaced ring bodies 522 are formed, and finally the complete frame body 52 as shown in Figure 2 is formed and output from the right side under the drive of the transmission chain 33;

[0052] In addition, since the flexible member 1 is located between the core 41 and the corresponding first forming groove 3311, when the first ring body 522 is formed, the inner wall of the ring body 522 and the outer wall of the flexible member 1 will bond together and be output forward with the ring body 522. At this time, the rotating feeding member 2 maintains rotation. With the continuous movement of the transmission chain 33, the subsequent multiple ring bodies 522 formed in sequence will also be connected to the outer wall of the flexible member 1 in sequence, and finally the flexible member 1 and the frame body 52 are effectively combined together to form the final finished product as shown in Figure 4 and output.

[0053] The special-shaped profile composite extrusion forming device in the above embodiment can efficiently process various complex special-shaped profiles. For complex special-shaped profile products with both continuous and discontinuous parts, one-time forming can be achieved, greatly improving the quality and production efficiency of the finished product, and also significantly reducing the production cost.

[0054] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the present invention.
