[0002] Insert molding of external plastic components is a technology that automatically embeds metal or non-metal inserts into plastic parts during the injection molding process. Currently, sheet-shaped metal inserts are typically placed precisely into the mold, followed by injection molding. The inserts combine with the plastic material to form a single component, reducing subsequent assembly steps.

[0003] However, current insert positioning generally involves manual placement or the addition of semi-automated robotic arms for collaborative operation. The matching and debugging process between such equipment and molds is cumbersome, the matching accuracy is insufficient, and errors are easily caused, resulting in inaccurate metal insert placement and removal trajectories, poor compatibility with injection molding equipment, which in turn leads to extended molding cycles, low overall processing efficiency, complex structures, and difficult maintenance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, an integrated molding structure for automatically inserting external components of a molded plastic includes a machine base 1. A drive mechanism 2 is installed on the top of the machine base 1. A long arm 3 is fixedly installed on the drive mechanism 2. Two linearly arranged gripping mechanisms 4 are installed on the long arm 3. A bottom mold 5 is fixedly installed on the machine base 1. Guide pillars 6 are fixedly connected to the bottom mold 5. A vertical hydraulic cylinder 7 is fixedly installed between the top ends of the guide pillars 6. A moving mold 8 is fixedly installed at the bottom end of the vertical hydraulic cylinder 7. The interior of the moving mold 8 is slidably connected to the outside between the two guide pillars 6. A conveyor belt 9 is installed on the right side of the top of the machine base 1. A feeding mechanism 10 is installed on the machine base 1. The feeding mechanism 10 is located on the left side of the bottom mold 5. An injection molding machine 11 is fixedly installed on the top of the guide pillars 6. The output end of the injection molding machine 11 is connected and fixedly connected to the feed port of the moving mold 8 through a flexible pipe.

[0022] In this invention, the machine base 1 serves as the main body of the device. During use, the metal sheet inserts are first vertically stacked and placed inside the feeding mechanism 10. Then, the vertical hydraulic cylinder 7 on the guide column 6 is activated to raise the moving mold 8 and separate it from the bottom mold 5. Next, the drive mechanism 2 is activated to move the long arm 3 linearly to the right until the first gripping mechanism 4 on the left side picks up an insert from inside the feeding mechanism 10. The drive mechanism 2 then moves the long arm 3 further until the gripping mechanism 4 with the insert moves onto the mold groove of the bottom mold 5. The gripping mechanism 4 is then activated to lower and place the insert into the mold groove. At this point, the gripping mechanism 4 on the right side is positioned above the conveyor belt 9, completing the initial feeding. The drive mechanism 2 is then activated to fully reset the long arm 3. The vertical hydraulic cylinder 7 is then activated to lower the moving mold 8 and close it with the bottom mold 5. Injection molding is then performed through the injection molding mechanism 11, allowing the insert to be directly integrated with the finished product during injection molding. After injection molding is complete, the drive mechanism 2 is activated to move the long arm... 3. Repeat the above movement, and at this time, the right gripping mechanism 4 first arrives above the bottom mold 5 to adsorb the finished product. The left gripping mechanism 4 simultaneously grips the insert. Then, the drive mechanism 2 is started to continue driving the long arm 3 to move to the right, so that the left gripping mechanism 4 with the finished product moves to the conveyor belt 9, while the gripping mechanism 4 with the insert moves to the bottom mold 5. At this time, both gripping mechanisms 4 release the material at the same time. The finished product is put into the output of the conveyor belt 9, and the insert is put into the mold groove of the bottom mold 5. Then the long arm 3 resets. Repeat the above operation to achieve continuous operation. This realizes that the device has an integrated design, better synchronization, increased equipment operating efficiency, more accurate material picking and placing, more compact structure, and easy maintenance. It solves the problems of existing technology and the addition of semi-automatic robotic arms for operation. However, the matching operation of such equipment is very complicated, the matching accuracy is poor, and errors are easy to occur, resulting in inaccurate picking and placing of metal inserts, poor fit with injection molding equipment, low overall efficiency, complex structure and difficult maintenance.

[0023] Please see Figure 1 and Figure 2 The feeding mechanism 10 includes a material bucket 101, a lifting cylinder 102, and a carrier plate 103. The bottom of the material bucket 101 is embedded and fixedly installed on the machine base 1. The lifting cylinder 102 is fixedly installed inside the machine base 1. The top of the lifting cylinder 102 passes through and slides to the inside of the material bucket 101. The top of the lifting cylinder 102 is fixedly connected to the carrier plate 103. The outer side of the carrier plate 103 is slidably connected to the inside of the material bucket 101.

[0024] In this utility model, the lifting cylinder 102 is activated to drive the carrier plate 103 to vertically push the inside of the material barrel 101 upward, so that it rises intermittently at equal distances according to the movement pattern of the long arm 3, thereby realizing automated material feeding and achieving the advantages of integrated operation of feeding, injection molding and unloading.

[0025] Please see Figure 1The drive mechanism 2 includes a servo motor 21, a lead screw 22, and a moving block 23. The servo motor 21 is fixedly installed on the left side of the machine base 1. The output end of the servo motor 21 is fixedly connected to the lead screw 22 through a coupling. The other end of the lead screw 22 passes through and is rotatably connected to the machine base 1. The bottom of the moving block 23 is slidably connected to the machine base 1. The outer side of the lead screw 22 is threadedly connected to the inside of the moving block 23. The bottom of the long arm 3 is fixedly connected to the top of the moving block 23.

[0026] In this invention, the servo motor 21 is started to drive the lead screw 22 to rotate, thereby driving the moving block 23 to move linearly along the machine base 1, thereby driving the long arm 3 to move, thus realizing the feeding of inserts.

[0027] Please see Figure 1 and Figure 3 The long arm 3 has a counterweight 31 fixedly connected to the bottom left end, and the counterweight 31 is located on the left side of the moving block 23.

[0028] In this invention, the counterweight 31 ensures that the weight on both sides of the long arm 3, with the moving block 23 as the support point, is evenly distributed, thus guaranteeing the stability of the equipment operation.

[0029] Please see Figure 1 and Figure 4 The gripping mechanism 4 includes a vertical cylinder 41 and an electric suction cup 42. The vertical cylinder 41 is fixedly installed on the long arm 3, and the bottom end of the vertical cylinder 41 is fixedly connected to the electric suction cup 42.

[0030] In this invention, the vertical cylinder 41 is activated to drive the electric suction cup 42 to descend and contact the insert for adsorption and gripping, thus achieving automated operation.

[0031] Please see Figure 1 Among them, a transparent protective cover 12 is fixedly installed on the top of the machine 1.

[0032] In this invention, the transparent protective cover 12 is used to protect the equipment, thereby improving the stability and safety of equipment operation.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
