The fixed module 8 and the movable module 9 are respectively clamped with the movable column 42.

[0029] Specifically, by rotating the rotating knob 36 on the fixed plate 6, the main rotating rod 37 and the main bevel gear 38 are driven to rotate together, thereby driving the cross thread rod 41 to rotate through the meshing main bevel gear 38 and the slave bevel gear 40, and then driving the two groups of moving columns 42 to move relative to each other along the two groups of moving grooves 43 with the cooperation of the symmetrical external threads.

[0032] Specifically, through the movable connection of the fixed shaft rod 52 and the rotating disc 53 and the cooperation of the screw ring 54, the two groups of rotating discs 53 rotate respectively until the two injection heads 56 of the required color are in the closest position. Then, the two bolts 58 pass through the two fixed blocks 57 respectively and are engaged with the two rotating discs 53 through the engaging holes 59 to fix the relative positions of the rotating disc 53 and the fixed disc 4. Immediately afterwards, through the threaded connection between the internal threaded ring plate 55 and the injection head 56, the two injection heads 56 are respectively connected to the two fixed modules 8, which can change and adjust the injection heads 56 according to the actual color requirements, with a relatively fast change rate, ensuring that the injection mold forms two-color products of different colors.

[0033] Working principle: First, when the movable module 9 is separated from the fixed module 8 for the first time, the first motor 10 on the outer side of the movable disk 5 is started through the control panel 35 to drive the first rotating shaft 11 and the half gear 12 to rotate together, so that the meshing half gear 12 and the full gear 14 cooperate with the driven shaft 13 and the bearing ring 15 to drive the rotating plate 7 to rotate 180° at intervals. After the rotating plate 7 rotates 180° each time, the second motor 19 on the load-bearing top plate 3 is started to drive the second rotating shaft 20 and the main gear 21 to rotate together, so that the cooperation of the main gear 21 and the serrated belt 23 drives the slave gear 22 to rotate, and then the threaded connection between the slave gear 22 and the slave threaded rod 24 cooperates with the two sets of limit vertical rods 26 on the top connecting plate 25 to drive the lifting plate 27 moves downward until the two groups of card rods 28 are respectively located at the inner sides of the two groups of card grooves 44 to limit the position of the rotating plate 7, and at the same time, the third motor 29 on one side of the vertical support plate 2 is started to drive the screw shaft 30 to rotate, so that the screw shaft 30 and the moving block 31 are threadedly connected to drive the moving block 31 to move laterally along the moving slide 32, and then the movable plate 5 is driven to move laterally along the supporting base 1 under the cooperation of the auxiliary block 33 and the auxiliary groove 34, and the moving module 9 is made to fit with the fixed module 8 under the cooperation of the four groups of connecting rods 17 and the four groups of connecting holes 18, and then the third motor 29 and the second motor 19 are started in reverse to separate the moving module 9 from the fixed module 8 again, and the intermittent rotation adjustment of the moving module 9 is realized by this cyclic operation. Function, there is no need to start and stop the motor during this process, and at the same time, when the moving module 9 and the fixed module 8 are molded together, the position offset of the moving module 9 relative to the movable disk 5 is avoided, thereby ensuring the placement stability of the moving module 9. Whenever the mold is demolded, the buffer plate 46 and several groups of buffer springs 47 and two groups of movable baffles 49 and torsion springs 50 cooperate with the limiting effect of four groups of movable vertical rods 48 and four groups of vertical sliding holes 51 to buffer the fall of the product, thereby ensuring the safety of the product. Secondly, the two groups of rotating disks 53 are rotated respectively through the movable connection of the fixed shaft rod 52 and the rotating disk 53 in cooperation with the screw ring 54 until the two groups of injection heads 56 of the required color are in the closest position, and then the two groups of clamping bolts 58 are respectively passed through the two groups of fixed blocks 57 in cooperation with the clamping holes 59 and the two groups of rotating disks 53 The two sets of injection heads 56 are connected to the two sets of fixed modules 8 respectively through the threaded connection between the internal thread ring plate 55 and the injection head 56, and the injection head 56 can be changed and adjusted according to the actual color requirements. The change rate is fast, ensuring that the injection mold can form two-color products of different colors. Finally, the main rotating rod 37 and the main bevel gear 38 are driven to rotate together by rotating the rotating knob 36 on the fixed plate 6, so that the cross thread rod 41 is driven to rotate through the meshing main bevel gear 38 and the slave bevel gear 40, and then the two sets of moving columns 42 are driven to move relative to each other along the two sets of moving grooves 43 under the cooperation of the symmetrical external threads. At this time, the two sets of fixed modules 8 can move relative to each other, and the same steps as above are followed.Rotating the rotary knob 36 on the rotating plate 7 can make the two groups of moving modules 9 move relative to each other, realizing the function of quick disassembly and replacement of the moving module 9 and the fixed module 8, so as to perform two-color injection molding of different types of products and complete the operation.
