[0025] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0026] like Figure 1-2 As shown, this utility model provides a dual-barrel, dual-color injection molding device for an injection molding machine, including a sliding table 1. An injection seat 2 is slidably connected to the top of the sliding table 1. A twin-screw injection barrel 3 is fixedly connected to the right end of the injection seat 2. Connecting seats 4 are fixedly connected to both the front and rear sides of the top of the injection seat 2. A barrel 5 is slidably inserted into the top of the connecting seats 4. The sliding table 1 includes a support base 11, and connecting ear plates 12 are fixedly connected to the four corners of the support base 11. The connecting ear plates 12 facilitate the installation of the device on the injection molding machine. An electric motor 13 is fixedly connected to the upper left side. The output shaft of the electric motor 13 passes through the inner side of the support base 11 and is fixedly connected to the transmission screw 14. A threaded hole 21 that passes through the left and right sides is opened in the lower part of the injection seat 2. The outer surface of the transmission screw 14 is threadedly connected to the inner surface of the threaded hole 21. Guide posts 15 are fixedly connected to the front and rear sides of the inner wall of the support base 11. A guide groove 22 that passes through the left and right sides is opened in the front and rear sides of the bottom of the injection seat 2. The outer surface of the guide post 15 is slidably connected to the inner surface of the guide groove 22.

[0027] When using the dual-barrel dual-color injection molding device, two different raw materials are placed inside the two barrels respectively. By starting the electric motor 13, the transmission screw 14 can be driven to rotate. Through the threaded engagement with the threaded hole 21, the injection seat 2 can be driven to slide along the guide post 15, which facilitates the docking of the twin-screw injection barrel 3 with the injection mold. Then, the raw material in the barrel will be injected into the injection mold from the twin-screw injection barrel 3 under the conveying of the injection seat 2, realizing the injection molding process of the workpiece.

[0028] like Figure 3As shown, this utility model provides a dual-barrel, dual-color injection molding device for an injection molding machine. The connecting seat 4 includes a connecting sleeve 41, which is fixedly connected to the top of the injection seat 2. The bottom of the outer surface of the barrel 5 is slidably inserted into the inner surface of the connecting sleeve 41. An annular groove is formed on the outer surface of the connecting sleeve 41, and a rotating ring 42 is rotatably connected inside the annular groove. A bevel gear ring 43 is fixedly connected to the lower part of the inner surface of the rotating ring 42. Bevel gears 44 are meshed on both the left and right sides above the outer surface of the bevel gear ring 43. The inner surface of the connecting sleeve 41 is provided with sliding grooves on both the left and right sides. The bevel gear 44 is fixedly connected to the side of the sliding groove with a threaded post 45. The end of the threaded post 45 away from the bevel gear 44 passes through the interior of the sliding groove and is threadedly connected to the outer surface with a threaded sleeve 46. The end of the threaded sleeve 46 away from the threaded post 45 is fixedly connected to an arc-shaped clamping plate 47. The outer surface of the arc-shaped clamping plate 47 is slidably connected to the inner surface of the sliding groove. Limiting posts 48 are fixedly connected to both the front and rear sides of the side of the arc-shaped clamping plate 47 near the threaded sleeve 46.

[0029] When installing the barrel 5, it is inserted into the connecting sleeve 41. By rotating the rotating ring 42, the bevel gear ring 43 drives the bevel gear 44 to rotate inside the annular groove, which in turn drives the threaded column 45 to rotate. Under the constraint of the arc-shaped clamping plate 47 and the limiting column 48, the threaded sleeve 46 can slide, which in turn pushes the arc-shaped clamping plate 47 to slide, so that the arc-shaped clamping plate 47 can be locked into the annular groove 52 to fix the barrel 5. At the same time, by simply rotating the rotating ring 42 in the opposite direction, the arc-shaped clamping plate 47 can be retracted, which makes it easy to disassemble the barrel 5 and facilitates the use of the dual-barrel dual-color injection molding device.

[0030] like Figure 4-5As shown, this utility model provides a dual-barrel, dual-color injection molding device for an injection molding machine. The barrel 5 includes a housing 51, which is slidably inserted into the top of the connecting seat 4. An annular groove 52 is provided at the bottom of the outer surface of the housing 51. A filter screen 53 is fixedly connected to the middle of the inner surface of the housing 51. A connecting block 54, which passes through vertically, is fixedly connected to the middle of the filter screen 53. A dual-head motor 55 is fixedly connected to the middle of the connecting block 54. The top output shaft of the dual-head motor 55 passes through to the top of the connecting block 54 and is fixedly connected to a rotating block 56. Crushing rollers 57 are movably connected to the left and right sides of the outer surface of the rotating block 56. A movable groove is provided at the bottom of the rotating block 56. One end of the crushing roller 57 near the rotating block 56 passes through the interior of the movable groove and is fixedly connected to a bevel gear 58. The two bevel gears 58... A conical ring 59 is engaged with the bottom of the outer surface of the 8. The conical ring 59 is fixedly connected to the top of the connecting block 54. The bottom output shaft of the dual-head motor 55 is fixedly connected to a rotating column 510. The bottom end of the rotating column 510 extends through to the bottom of the connecting block 54 and is fixedly connected to a base plate 511. A clamping spring 512 is fixedly connected to the top of the base plate 511. A lifting slide plate 513 is fixedly connected to the top of the clamping spring 512. The lifting slide plate 513 is slidably connected to the outer surface of the rotating column 510. An arc-shaped top plate 514 is fixedly connected to the top of the lifting slide plate 513. Protrusions 541 are fixedly connected to the left and right sides of the bottom of the connecting block 54. Several vibrating blocks 515 are fixedly connected to the top of the lifting slide plate 513 in a ring array. The vibrating blocks 515 are set at the bottom of the filter screen 53.

[0031] When raw materials are fed in, the filter screen 53 filters larger materials in the barrel 5. By starting the dual-head motor 55, the rotating block 56 drives the crushing roller 57 to rotate. Through the meshing of the bevel gear 58 and the bevel gear ring 59, the bevel gear 58 drives the crushing roller 57 to rotate, which facilitates the crushing of larger materials on the filter screen 53. The dual-head motor 55 also drives the rotating column 510 to rotate. Under the pushing action of the protrusion 541 and the arc-shaped top plate 514, the lifting slide plate 513 slides downward. Under the pushing action of the clamping spring 512, the lifting slide plate 513 drives the vibrating hammer block 515 to strike the filter screen 53, which improves the filtering effect of the filter screen 53 on the raw materials. This ensures that the raw materials are of uniform size during melt injection, allowing the raw materials to be fully melted and avoiding any impact on the injection molding effect of the workpiece. This makes the use of the dual-barrel dual-color injection molding device more convenient.

[0032] The working principle of this dual-barrel, dual-color injection molding device for injection molding machines will be explained in detail below. For example... Figure 1-5As shown, when using the dual-barrel, dual-color injection molding device, the barrel 5 is inserted into the connecting sleeve 41. By rotating the rotating ring 42, the bevel gear ring 43 drives the bevel gear 44 to rotate, which in turn causes the threaded column 45 to slide the threaded sleeve 46. This pushes the arc-shaped clamping plate 47 into the annular groove 52, thus fixing the barrel 5. Then, two different raw materials are placed inside the two barrels respectively. The filter screen 53 filters the larger raw materials in the barrel 5. By starting the dual-head motor 55, the rotation... The moving block 56 drives the crushing roller 57 to rotate, and through the meshing of the bevel gear 2 58 and the bevel gear ring 2 59, it can drive the crushing roller 57 to rotate, which facilitates the crushing of larger raw materials. Then, by starting the electric motor 13, it can drive the transmission screw 14 to rotate, and through the threaded engagement with the threaded hole 21, it can drive the injection seat 2 to slide along the guide post 15, which can facilitate the docking of the twin-screw injection barrel 3 with the injection mold. Then, the raw material in the barrel will be injected into the injection mold from the twin-screw injection barrel 3 under the conveying of the injection seat 2, realizing the injection molding of the workpiece.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
