[0035] like Figure 3 The mold closing box 3 is provided with a movable mold 6, and the movable mold 6 is located above the static mold 5. The mold closing box 3 is provided with a mold closing component 7 which drives the movable mold 6 to separate from one static mold 5 and then immediately transfer it to another static mold 5 for mold closing.

[0036] like Figure 3 and Figure 4 The mold clamping assembly 7 includes a transverse plate 71, which is slidably arranged in the mold clamping box 3. The transverse plate 71 can move laterally in the box. A first vertical groove 711 is opened on one side of the transverse plate 71, and the first vertical groove 711 is located on the side of the transverse plate 71 close to the movable mold 6.

[0037] like Figure 3 and Figure 4 A connecting member 8 is provided on the transverse plate 71 for driving the movable mold 6 to move up and down reciprocatingly. The connecting member 8 includes a guide plate 81. A transverse groove 811 is provided on the guide plate 81. Two connecting blocks 812 are provided at the bottom of the guide plate 81. The connecting blocks 812 correspond to the second vertical grooves 712 one by one. A connecting rod 813 is passed through the connecting block 812. One end of the connecting rod 813 is located in the second vertical groove 712 and can slide along the second vertical groove 712. The ends of the two connecting plates facing away from the second vertical groove 712 are commonly connected to a push rod 82, and the push rod 82 is connected to the movable mold 6.

[0038] like Figure 3 and Figure 5 A guide rod 83 is rotatably connected to the mold closing box 3 , and a rotating shaft 84 is provided at one end of the guide rod 83 . One end of the rotating shaft 84 is located in the transverse groove 811 and can move along the transverse groove 811 .

[0039] like Figure 6 , Figure 7 and Figure 8 The mold clamping box 3 is provided with a second motor 72, and the driving shaft of the second motor 72 is connected with a first turntable 73 and a second turntable 85. The transverse plate 71, the guide plate 81, the guide rod 83 and the push rod 82 are all located between the first turntable 73 and the second turntable 85. The first turntable 73 is provided with a first guide groove 74 on the side facing the second turntable 85, and the first guide groove 74 includes a V-shaped groove 741 and an arc groove 742, and the V-shaped groove 741 and the arc groove 742 are connected end to end to form a closed annular groove, and the second turntable 85 is provided with a second guide groove 86 on the side facing the first turntable 73, and the second guide groove 86 is a diamond groove 861.

[0040] A swing rod 75 is rotatably connected in the mold clamping box 3. The swing rod 75 is an L-shaped rod. One end of the swing rod 75 is slidably connected to the first guide groove 74, and the other end of the swing rod 75 is slidably connected to the first vertical groove 711. The end of the rotating shaft 84 on the guide rod 83 that is away from the horizontal groove 811 is located in the second guide groove 86 and can slide along the second guide groove 86.

[0041] The heating system 2 melts the thermoplastic, and the molten thermoplastic is transmitted to the injection system 1. The injection system 1 injects the thermoplastic into the diversion injection molding pipe 41. The first motor 42 drives the rotating disk 43 to rotate. The guide groove 431 of the rotating disk 43 guides the moving rod 44 to drive the blocking block 46 to move when the rotating disk 43 rotates to block one of the discharge ports 412 of the diversion injection molding pipe 41.

[0042] During injection molding, the thermoplastic is slowly injected into the static mold 5 from bottom to top, and the thermoplastic squeezes out the air in the bypass injection molding pipe 41 and the air in the static mold 5, thereby reducing the appearance of bubbles on the injection molding surface after production is completed, and achieving seamless production of the surface of thin-walled injection molding products.

[0043] When the injection molding of the first static mold 5 is completed, the rotating disk 43 continues to rotate so that the moving rod 44 drives the blocking block 46 to separate from the discharge port 412, and blocks the discharge port 412 that has been injected.

[0044] When the mold is closed, the second motor 72 drives the first turntable 73 and the second turntable 85 to rotate. The first guide groove 74 guides the swing rod 75 to swing when the first turntable 73 rotates. One end of the swing rod 75 moves up and down along the first vertical groove 711 of the transverse plate 71. At the same time, the swing rod 75 pushes the transverse plate 71 to move laterally. When the transverse plate 71 moves, it drives the guide plate 81 and the push rod 82 to move, so that the push rod 82 can drive the movable mold 6 to move toward the static mold 5.

[0045] When the guide plate 81 and the push rod 82 move, the second guide groove 86 of the second turntable 85 guides the guide rod 83 to rotate, and the guide rod 83 moves along the transverse groove 811 of the guide plate 81 and pushes the guide plate 81 to move downward, so that the guide plate 81 drives the push rod 82 to move downward so that the movable mold 6 is molded with the aligned static mold 5. At this time, the swing rod 75 is at the bottom of the V-shaped groove 741, and the guide rod 83 is just located at the acute angle end of the diamond groove 861.

[0046] When the injection molding of the static mold 5 is completed, the first turntable 73 and the second turntable 85 continue to rotate, and the second guide groove 86 first guides the guide rod 83 to drive the guide plate 81 to move upward along the second vertical groove 712, so that the push rod 82 drives the dynamic mold 6 and the static mold 5 to be demolded, and then the first guide groove 74 just guides the swing rod 75 to push the transverse plate 71 to move so that the dynamic mold 6 is aligned with the other static mold 5. At this time, the first turntable 73 and the second turntable 85 continue to rotate. Since the swing rod 75 is located in the arc groove 742 at this time, the transverse plate 71 stops moving, and the guide rod 83 continues to move along the hypotenuse of the diamond groove 861, so that the guide rod 83 drives the guide plate 81 to move downward to drive the dynamic mold 6 and the other static mold 5 to be molded.

[0047] By repeatedly repeating the above operations, a cyclic action is achieved in which the movable mold 6 moves forward laterally to align with the static mold 5, the movable mold 6 moves downward to close the mold with one static mold 5, the movable mold 6 moves upward to remove the mold, the movable mold 6 moves backward to align with another static mold 5, and the movable mold 6 moves downward to close the mold with another static mold 5.

[0048] The relationship between the position of the swing rod 75 in the first guide groove 74 and the position of the guide rod 83 in the second guide groove 86 is as follows: When the swing rod 75 is at the bottom of the V-shaped groove 741, the guide rod 83 is just located at the acute angle end of the diamond groove 861. At this time, the movable mold 6 is just molded with a static mold 5. When the first turntable 73 rotates, the swing rod 75 moves along the hypotenuse of the V-shaped groove 741, so that the swing rod 75 drives the transverse plate 71 to move horizontally. Just after the transverse plate 71 drives the movable mold 6 to align with a static mold 5, the swing rod 75 is located in the arc groove 742. At this time, the transverse plate 71 stops moving. When the swing rod 75 passes the hypotenuse of the V-shaped groove 741 again, the transverse plate 71 moves horizontally in the opposite direction. At the same time, as the second turntable 85 moves, the guide rod 83 moves along the hypotenuse of the diamond groove 861, so that the guide rod 83 drives the guide plate 81 to move upward first and then gradually move downward. When the guide rod 83 is located at the other acute-angle end of the diamond groove 861, the movable mold 6 just closes with the other static mold 5.

[0049] The implementation principle of the embodiment of the present application is as follows: the diverter component 4 in the mold closing box 3 allows the molten hot plastic to flow into one of the static molds 5, and the mold closing component 7 controls the movable mold 6 to fit with the static mold 5 to be injected with the hot-melt hot plastic, thereby realizing the production of injection molded parts. When the static mold 5 is injection-molded and cooled to form, the mold closing component 7 controls the movable mold 6 to separate from the static mold 5 and to close the mold with another static mold 5, and then the diverter component 4 guides the hot plastic to be injected into the other static mold 5. When the other static mold 5 is being injection-molded, the robot takes the product out of the static mold 5. When the injection molding of the other static mold 5 is completed, the above operation is repeated to avoid the movable mold 6 being idle during the robot's material taking process, thereby improving the production efficiency of injection molded products.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
