[0031] like Figure 1-5 As shown, a quick-assemble and disassemble extruder die head in this embodiment includes a die head body 1, the die head body 1 includes a connecting portion 11 and a main body 12, the main body 12 is used to connect to the injection molding machine body 2, and a support mechanism 3 and a connecting mechanism 4 are connected to the die head body 1, the support mechanism 3 is connected to the main body 12, and the connecting mechanism 4 is connected to the connecting portion 11;

[0032] The supporting mechanism 3 includes a first fixed plate 31, a first rotating plate 32, a second rotating plate 33 and a supporting rod 34. One side of the first rotating plate 32 is hinged to one side of the second rotating plate 33. The side of the first rotating plate 32 away from the second rotating plate 33 is rotatably connected to the supporting rod 34. The side of the second rotating plate 33 away from the first rotating plate 32 is hinged to the first fixed plate 31. The supporting rod 34 is vertically arranged. The top end of the supporting rod 34 is detachably fixed on the main body 12. The supporting rod 34 is threadedly connected to the main body 12. During operation, the first fixed plate 31 is fixed in the installation position. When the connecting part 11 needs to be connected to the injection molding machine body 2, the main body 12 is pushed to move. At this time, the supporting rod 34 is hinged to the first rotating plate 32. The plates 32 rotate relative to each other, and the rotation center line is coaxial with the support rod 34. The first rotating plate 32 and the second rotating plate 33 rotate relative to each other, and the rotation center line is vertical. The second rotating plate 33 rotates relative to the first fixed plate 31, and the rotation center line is vertical. In fact, the first rotating plate 32 and the second rotating plate 33 form a hinge plate structure. The weight of the die body 1 is transmitted to the installation position of the first fixed plate 31 through the support rod 34, the first rotating plate 32, the second rotating plate 33 and the first fixed plate 31 in sequence, thereby supporting the die body 1 and allowing the die body 1 to move freely in the horizontal direction, which is convenient for disassembly and assembly of the die body 1 on the injection molding machine, saving disassembly and assembly time, that is, realizing rapid disassembly and assembly of the die body 1.

[0033] The connecting mechanism 4 includes a mounting frame 41, on which a clamping hoop assembly 42 is provided. During use, the mounting frame 41 is fixedly provided at the mounting position. When the connecting portion 11 is moved to the injection molding machine body 2, the clamping hoop assembly 42 aligns the connecting portion 11 with the injection molding machine body 2, and the connecting portion 11 and the injection molding machine body 2 are relatively fixed, thus completing the installation of the die body 1. When the die body 1 needs to be disassembled, the clamping hoop assembly 42 can be operated in reverse.

[0034] The clamp assembly 42 includes a support bar 421 and two clamp bars 422, and the two clamp bars 422 are symmetrically arranged. The support bar 421 and the two clamp bars 422 are surrounded to form an annular structure. The support bar 421 is fixedly set on the mounting frame 41, and the two ends of the clamp bar 422 are respectively a hinged end and a locking end. The hinged end of the clamp bar 422 is hinged to the mounting frame 41. Among the two clamp bars 422, the locking end of one clamp bar 422 and the locking end of the other clamp bar 422 are locked by a first locking member 423. When the mold main body needs to be installed on the injection molding machine body 2, the first locking member 423 is unlocked, so that the clamp bar 422 rotates around the hinge point between the clamp bar 422 and the mounting frame 41. The two clamping bars 422 are moved, that is, the two clamping bars 422 are opened, and then the connecting part 11 is moved between the two clamping bars 422 and fits the connecting side of the injection molding machine body 2. In fact, the connecting side of the injection molding machine body 2 and the connecting part 11 is always in the annular structure. Then, the two clamping bars 422 are rotated in the opposite direction to achieve reset, that is, the connecting part 11 is located in the annular structure, and finally the two clamping members are locked by the first locking member 423, so that the support bar 421 and the two clamping bars 422 can tighten the connecting part 11 and the injection molding machine body 2 at the same time, thereby realizing the installation of the die head body 1, wherein, by tightening the connecting part 11 by the support bar 421 and the two clamping bars 422, the connecting part 11 can also be aligned with the injection molding machine body 2;

[0035] The mounting frame 41 includes a second fixed plate 411, a movable plate 412 is provided on one side of the second fixed plate 411, a plurality of guide rods 413 are passed through the movable plate 412, and the plurality of guide rods 413 are arranged side by side. The specific number of the guide rods 413 is two, and the guide rods 413 are arranged horizontally. The movable plate 412 is locked with the guide rods 413 by a second locking member 414. Two support columns 415 are fixedly provided on the movable plate 412, and the support bars 421 are fixedly provided on the two support columns 415. The two support columns 415 are connected to the two support bars 421. The clamping bars 422 correspond one to one, and the support column 415 is hinged to the hinged end of the clamping bar 422. When it is necessary to adjust the distance between the connection side of the injection molding machine and the connection part 11 inserted into the annular structure, the second unlocking piece is unlocked to move the movable plate 412 on the guide rod 413. In fact, the moving direction of the movable plate 412 on the guide rod 413 is parallel to the axis of the annular structure, so that the distance between the connection side of the injection molding machine and the connection part 11 inserted into the annular structure can be adjusted. After the adjustment is completed, the second unlocking piece is used to lock the movable plate 412 and the guide rod 413.

[0036] For ease of operation, handles 424 are provided on both clamp bars 422;

[0037] To sum up, the support mechanism 3 is used to support the die body 1 to move freely in the horizontal direction, which facilitates the disassembly and assembly of the die body 1 on the injection molding machine, saves disassembly and assembly time, and realizes the rapid disassembly and assembly of the die body 1. In addition, the connecting mechanism 4 can realize the rapid docking and separation of the connecting part 11 and the injection molding machine body 2, which further improves the disassembly and assembly efficiency of the die body 1.

[0038] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
