[0023] Example: Reference Figure 1-5A forming device for processing a plastic hanger is shown, comprising a base plate 1, a motor 6 is installed on the side of the base plate 1, a moving block 5 is arranged above the base plate 1, grooves are provided on the top of the base plate 1 and the bottom of the moving block 5, two bidirectional screw rods 7 are rotatably installed on the opposite inner walls of the two grooves, one end of one of the bidirectional screw rods 7 is installed on the output shaft of the motor 6, the two bidirectional screw rods 7 are installed through a transmission mechanism, two L-shaped clamping plates 8 are threadedly sleeved on the two bidirectional screw rods 7, a lower mold 9 and an upper mold 10 are arranged above the base plate 1, a plurality of mounting holes are provided on the top of the moving block 5, injection molding tubes 20 are installed in the plurality of mounting holes, a limiting block 11 is installed on the bottom of the lower mold 9 and the top of the upper mold 10, the sides of the two limiting blocks 11 away from each other are provided with slots adapted to the L-shaped clamping plates 8, and a lifting mechanism adapted to the moving block 5 is arranged on the base plate 1.

[0024] By means of the above mechanism, when in use, first place the lower mold 9 on the bottom plate 1 and make the limit block 11 in the groove, then place the upper mold 10 on the lower mold 9, and make the limit block 11 on the upper mold 10 face upwards, then lower the moving block 5 through the lifting mechanism, when the moving block 5 contacts the upper mold 10, the motor 16 outputs, and the motor 6 output will rotate the two bidirectional screw rods 7 through the transmission mechanism, the rotation of the two bidirectional screw rods 7 will respectively make the four L-shaped clamps 8 approach each other, the two L-shaped clamps 8 approach each other will clamp the limit block 11, and then fix the two limit blocks 11, so as to fix the lower mold 9 and the upper mold 10 at the same time, which is convenient for use, when fixed, connect the external injection molding machine to the injection molding tube 20, and then process and shape through the lower mold 9 and the upper mold 10.

[0025] like Figure 2 As shown, the lifting mechanism includes four fixed boxes 2 installed on the top of the base plate 1, and the relative inner walls of the four fixed boxes 2 are rotatably installed with threaded rods 3, a motor 21 is installed on the top of one of the fixed boxes 2, one end of one of the threaded rods 3 is installed on the output shaft of the motor 21, and threaded blocks 4 are threadedly sleeved on the four threaded rods 3. The moving blocks 5 are installed on the sides of the four threaded blocks 4, and the four threaded blocks 4 are installed through a transmission unit. The advantage of this arrangement is that the moving block 5 is easy to lift and lower through the arrangement of the threaded rods 3, the threaded blocks 4 and the threaded rods 3.

[0026] Specifically, the output of the motor 21 causes the threaded rod 3 to rotate, and the rotation of the threaded rod 3 causes the threaded block 4 to move up and down, and the lifting and moving of the threaded block 4 causes the moving block 5 to move up and down, so that when the processing is completed, the hanger can be taken out for easy use.

[0027] like Figure 5As shown, the transmission unit includes a circular cavity opened on the base plate 1, the bottom ends of the four threaded rods 3 extend into the circular cavity and are installed with sprockets 17, and the four sprockets 17 are jointly meshed and installed with chains 18. The advantage of this arrangement is that the four threaded rods 3 can rotate simultaneously through the arrangement of the sprockets 17 and the chains 18.

[0028] Specifically, when one of the threaded rods 3 rotates, one of the sprockets 17 will rotate, and the rotation of the sprocket 17 will cause the other three sprockets 17 to rotate through the chain 18, and the rotation of the other three sprockets 17 will rotate the other three threaded rods 3, so that the four threaded rods 3 rotate at the same time, making the lifting and lowering of the moving block 5 more stable.

[0029] like Figure 4 As shown, the transmission unit includes fixed blocks 12 respectively installed on the side of the base plate 1 and the side of the moving block 5, and a transmission cavity is opened on the two fixed blocks 12. One end of the two bidirectional screw rods 7 extends to the two transmission cavities and is installed with a first bevel gear 14 respectively. A movable hole is opened on the top of the fixed block 12 located at the bottom, and a movable column 13 is rotatably installed in the movable hole. A movable rod 15 is rotatably installed on the top inner wall of the transmission cavity located at the top, and a rectangular cavity is opened on the movable column 13. One end of the movable rod 15 extends into the rectangular cavity and is installed with a rectangular block. The movable column 13 and the movable rod 15 are both sleeved with a second bevel gear 16, and the two second bevel gears 16 are respectively meshed with the two first bevel gears 14. The advantage of such an arrangement is that, through the arrangement of the fixed block 12, the movable column 13, the first bevel gear 14, the movable rod 15, the rectangular block and the second bevel gear 16, it is convenient to make the two bidirectional screw rods 7 rotate simultaneously.

[0030] Specifically, the rotation of one of the two-way screw rods 7 will cause one of the first bevel gears 14 to rotate, and the rotation of one of the first bevel gears 14 will cause the movable column 13 to rotate through one of the second bevel gears 16, and the rotation of the movable column 15 will cause the movable rod 15 to rotate through the rectangular block, and the rotation of the movable rod 15 will cause another two-way screw rod 7 to rotate through another first bevel gear 14 and another second bevel gear 16, thereby causing the two two-way screw rods 7 to rotate at the same time. At the same time, through the arrangement of the movable column 13, the movable rod 15 and the rectangular block, when the moving block 5 rises, the upper two-way screw rod 7 can still be rotated, thereby facilitating the fixation of molds of different thicknesses and facilitating use.

[0031] like Figure 3 As shown, guide rods 19 are installed on the relative inner walls of the two grooves, and guide holes are opened on the sides of the four L-shaped clamps 8. One guide rod 19 passes through two of the guide holes in sequence. The advantage of this arrangement is that the L-shaped clamps 8 can move in the horizontal direction through the setting of the guide rods 19.

[0032] like Figure 3As shown, buffer pads are installed on the sides of the four L-shaped clamps 8. The advantage of this arrangement is that the buffer pads can play a certain buffering role and avoid excessive vibration caused by the L-shaped clamps 8 clamping the limit blocks 11.

[0033] like Figure 1 As shown, four supporting legs are installed at the bottom of the base plate 1, and shock-absorbing pads are installed at the bottom of the four supporting legs. The advantage of this arrangement is that the setting of the supporting legs facilitates the support of the base plate 1, and the setting of the shock-absorbing pads plays a certain buffering role, reducing the impact of vibration on injection molding.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
