[0022] like Figure 1-Figure 3As shown, it also includes a second cylinder 13, a top plate 14, a spring 15 and a push rod 16. A second cylinder 13 is arranged between the bottom of the slide 4 and the top of the bracket 3. A push plate 14 is arranged on the piston rod of the second cylinder 13. The second cylinder 13 provides power to drive the push plate 14 to move up and down. The two sides of the push plate 14 are slidably connected to the lower mold 6. The middle part of the push plate 14 is raised and slides into the inner middle part of the lower mold 6. The push plate 14 drives the push rod 16 to lift the formed plastic button for easy removal. A spring 15 is arranged between the top plate 14 and the two sides of the lower mold 6. The spring 15 provides elastic force to ensure that the top plate 14 is smoothly reset. A push rod 16 is arranged on the top of the top plate 14 and on the inner side of the springs 15 on both sides. The upper part of the push rod 16 slides into the upper part of the lower mold 6.

[0023] like Figure 1-Figure 2 As shown, it also includes a cooling box 17, a cooling pipe 171 and a solenoid valve 172. A cooling box 17 is provided in the middle position on the rear side of the machine base 1. The cooling box 17 stores coolant to help cooling. Cooling pipes 171 are connected on both sides of the outside of the upper mold 7. The cooling pipes 171 transport coolant to the mold. The cooling pipes 171 on both sides correspond to the two cavities of the upper mold 7. The rear parts of the cooling pipes 171 on both sides are connected to the two sides of the cooling box 17, and the front parts of the cooling pipes 171 on both sides are provided with solenoid valves 172. The solenoid valves 172 control the switching of the cooling pipes 171.

[0024] like Figure 1 and Figure 4 As shown, it also includes a mounting plate 18, a pneumatic clamp 19 and an electric cylinder 20. The mounting plate 18 is set on the right side of the slide 4 by screws, and a pneumatic clamp 19 is slidably set on the left middle part of the mounting plate 18. The pneumatic clamp 19 is used to clamp the formed plastic button. The electric cylinder 20 is set on the right middle part of the mounting plate 18, and the piston rod of the electric cylinder 20 is connected to the sliding part connected to the pneumatic clamp 19.

[0025] like Figure 1 and Figure 2 As shown, a controller 121 is also included. The controller 121 is installed at the upper rear portion of the machine base 1. The controller 121 is electrically connected to the first cylinder 2, the heating ring 91, the conveyor 11, the electric slide 12, the second cylinder 13, the solenoid valve 172 and the electric cylinder 20. The operating status of each component can be monitored and managed in real time through the controller 121 to maintain the entire device.

[0026] When in use, first turn on the power of the controller 121 and initialize each component, such as the first cylinder 2, the heating ring 91, the conveyor 11, the electric slide 12, the second cylinder 13, the solenoid valve 172 and the electric cylinder 20. The controller 121 checks whether each component is in the initial state and is ready to start production. The first cylinder 2 is started, the piston rod is extended, and the bracket 3 is driven to rise, so that the lower mold 6 on the slide 4 is docked with the upper mold 7 and tightly fitted. The contact surface between the upper mold 7 and the lower mold 6 should ensure a tight fit to prevent leakage during injection molding. The conveyor 11 feeds the molten plastic into the injection tube 9 through the material tank 10. The injection tube 9 keeps the plastic in a molten state under the action of the outer heating ring 91, and injects the plastic into the material collecting seat 8 of the upper mold 7 through the injection tube 9. The plastic flows into the mold groove of the upper mold 7 through the material hole of the material collecting seat 8 to fill the mold cavity. After the injection molding is completed, the cooling box 17 delivers coolant to the mold through the cooling pipe 171, so that the plastic in the mold is quickly cooled and solidified. The coolant circulates through the cooling pipe 171 inside and outside the mold, takes away heat and speeds up the cooling speed. The first cylinder 2 retracts, driving the lower mold 6 to separate from the upper mold 7. The second cylinder 13 is started, the piston rod extends, and pushes the top plate 14 to rise. The molded key is ejected from the lower mold 6 through the ejector rod 16. The rising action of the top plate 14 is precisely controlled by the second cylinder 13 to ensure that the ejection force is moderate and the finished product is not damaged. The electric cylinder 20 drives the pneumatic clamp 19 to clamp the molded key out and place it in the specified position. The pneumatic clamp 19 is driven by the electric cylinder 20 to accurately grab the key and place it steadily on the conveyor belt or the specified position. After completing one injection molding, the above steps are repeated for continuous production. The controller 121 monitors the entire process to ensure the consistency and accuracy of each production.
