[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0022] like Figure 1-4 As shown, an automated production injection molding machine includes: a rotating platform, which has a rotating disk 2 and can drive the rotating disk 2 to rotate; a mold assembly, which has multiple mold assemblies and is evenly distributed circumferentially around the rotating disk 2, the mold assembly has an upper mold 3, a lower mold 4, and a pressure bar 21, and can push the lower mold 4 to be combined with the upper mold 3, and the pressure bar 21 is fixed to the side of the lower mold 4; an injection molding assembly, which is used to transport molten material to the mold assembly; a conveying assembly, which has a frame 17 and can drive the frame 17 to change position, and the frame 17 is provided with two pressing plates 20 for contacting the pressure bar 21, and there is a gap between the two pressing plates 20 for the upper mold 3 and the lower mold 4 to pass through.

[0023] Specifically, the rotating platform is the prior art and will not be described in detail. The upper mold 3 and the lower mold 4 are arranged up and down. The lower mold 4 is pushed to move so that it can be combined with the upper mold 3 to form an injection molding cavity. The pressure bar 21 is pressed by the frame 17 to make the lower mold 4 descend. After the lower mold 4 descends, the molded injection molded part follows it to descend, which makes it easy to take out the injection molded part. At the same time, multiple mold assemblies can realize injection molding and take out the injection molding machine at the same time, which improves efficiency.

[0024] Furthermore, the mold assembly also has a slide bar 5 and a spring 6. There are two slide bars 5, and the spring 6 is sleeved on the slide bar 5. The slide bar 5 passes through the lower mold 4, and the two slide together to support the lifting and lowering of the lower mold 4. The upper mold 3 is fixedly arranged on the top of the slide bar 5 to facilitate the combination of the upper mold 3 and the lower mold 4. An injection port 10 is arranged on the top of the upper mold 3.

[0025] Specifically, the lower mold 4 can be raised and lowered on the slide bar 5. When the lower mold 4 descends, it squeezes the spring 6. The thrust of the spring 6 can push the lower mold 4 to lift, so that the lower mold 4 returns to its original position, and then combines with the upper mold 3. The injection molding assembly injects the molten material into the molding cavity formed by the upper mold 3 and the lower mold 4 through the injection port 10.

[0026] Furthermore, the transport component also has a linear slide 15, a lifting cylinder 16, a material picking telescopic cylinder 18 and a clamping cylinder 19. The lifting cylinder 16 is fixedly connected to the slider of the linear slide 15, and the linear slide 15 can drive the lifting cylinder 16 to translate. The frame 17 is fixedly connected to the telescopic end of the lifting cylinder 16, and the lifting cylinder 16 can drive the frame 17 to lift and lower. The material picking telescopic cylinder 18 is fixedly installed on the side of the frame 17. The telescopic end of the material picking telescopic cylinder 18 is provided with a clamping cylinder 19, and the material picking telescopic cylinder 18 can drive the clamping cylinder 19 to translate to help the clamping cylinder 19 grab the molded injection molded parts.

[0027] Specifically, the frame 17 is rectangular in shape, and the linear slide 15 can drive the lifting cylinder 16 to move, and then the frame 17 moves, so as to facilitate the transportation of the injection molded workpiece clamped by the clamping cylinder 19.

[0028] Furthermore, the injection molding assembly has an injection system 12 and an injection cylinder 13. The injection system 12 is arranged at the telescopic end of the injection cylinder 13, and can drive the injection system 12 to rise and fall.

[0029] Specifically, the injection cylinder 13 extends and retracts to drive the injection system 12 to rise and fall, so that the injection port of the injection system 12 can enter the injection port 10, and then transport the molten material into the molding cavity formed by 3 and 4, and 13 contracts to drive 12 away from 3.

[0030] Furthermore, it also includes a workbench 1, a first bracket 11 and a second bracket 14, the injection molding component is arranged on the first bracket 11, the transport component is arranged on the second bracket 14, and the rotating platform, the first bracket 11 and the second bracket 14 are all arranged on the workbench 1.

[0031] Specifically, the linear slide 15 is fixedly arranged on the second bracket 14 to drive the lifting cylinder 16 to translate, and the injection cylinder 13 is fixedly arranged on the first bracket 11 to drive the injection system 12 to move up and down.

[0032] Furthermore, the mold assembly also has a push column 8 and a demolding top block 9. A cavity 7 is provided on the side of the lower mold 4 facing the upper mold 3. The injection port 10 is connected to the cavity 7. The push column 8 is vertically fixedly connected to the rotating disk 2. A demolding top block 9 is fixedly provided on the top of the push column 8. An opening matching the size of the demolding top block 9 is provided at the bottom of the lower mold 4, and the surface of the demolding top block 9 matches the bottom surface of the cavity 7.

[0033] Specifically, the injection port 10 is connected to the cavity 7, and the cavity 7 is used to receive the molten material delivered by the injection mold and then form it. The demolding top block 9 is adapted to the bottom surface of the cavity 7 so that the material contacting the surface of the demolding top block 9 can form a set shape and size. At the same time, after the lower mold 4 descends, the injection molded part in the cavity 7 is ejected by the demolding top block 9, which is convenient for the gripper cylinder 19 to grasp it.

[0034] In the above structure, the rotating disk 2 rotates to move the upper mold 3 to the bottom of the injection system 12, and then the injection cylinder 13 is extended and retracted to drive the injection system 12 to rise and fall, so that the injection system 12 can enter the injection port 10 to transport the molten material into the cavity 7. After transportation, the injection system 12 is lifted, and the rotating disk 2 continues to rotate. The above steps are repeated to realize continuous injection molding. When the upper mold 3 after injection and cooling moves to the bottom of the frame 17, the lifting cylinder 16 is extended to drive the frame 17 to descend. During the descent of the frame 17, the edge of the pressing plate 20 presses the pressure strip 21, so that the lower mold 4 descends along the slide bar 5, and then the molded injection product follows the lower mold 4 to descend, and a gap is generated between the upper mold 3 and the lower mold 4. At this time, the molded product is released. The mold top block 9 ejects the molded injection product and places the injection product between the upper mold 3 and the lower mold 4. Then the material-taking telescopic cylinder 18 is started to extend, so that the clamping claw cylinder 19 approaches the injection product and clamps it. Then, the material-taking telescopic cylinder 18 is started to contract to take away the injection product. Then the lifting cylinder 16 is started to contract and the frame 17 is lifted. At the same time, the linear slide 15 can drive the lifting cylinder 16 to move, and then the frame 17 moves, which is convenient for transporting the injection molded workpiece. After the pressure strip 21 is released, the spring 6 squeezed by the lower mold 4 pushes the lower mold 4 back to its original position, so that the upper mold 3 and the lower mold 4 are combined to prepare for the next injection molding. By repeating the above operations, automatic continuous production of injection molded products can be achieved, thereby improving production efficiency.
