[0002] Mouse button molding die is an injection mold system specifically designed for manufacturing irregularly shaped mouse buttons. The injection molding of mouse buttons is typically divided into three stages: mold closing, injection, and demolding.

[0003] Because mouse buttons are irregularly shaped and thin, and because there is a vacuum adsorption between the molded mouse button and the lower mold cavity, it would be difficult to demold using the traditional ejector pin method, and it might even damage the molded mouse button. Therefore, a mouse button molding mold is needed. Utility Model Content

[0024] 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;

[0025] Please see Figures 1-5 In this utility model: a mouse button forming mold includes a lower mold 1, a mold groove is provided on the top of the lower mold 1, an upper mold 2 is provided above the lower mold 1, a protrusion adapted to the mold groove is fixedly connected to the bottom of the upper mold 2, a cavity 3 is provided on the lower mold 1, an electric push rod 4 is inserted through the inner wall of the cavity 3 and fixedly connected thereto, a lifting plate 5 is fixedly connected to the telescopic end of the electric push rod 4, two push rods 6 are fixedly connected to the top of the lifting plate 5, two through holes 7 adapted to the push rods 6 are provided on the lower mold 1, the top ends of the two push rods 6 extend into the mold groove through the two through holes 7 respectively, a three-way pipe 8 is inserted through the inner wall of the cavity 3, the left and right ends of the three-way pipe 8 both penetrate the lower mold 1 and extend to the inner wall of the two through holes 7 respectively, an air pump 9 is installed at the bottom end of the three-way pipe 8, and a lifting block 12 fixedly connected thereto is sleeved on the upper mold 2.

[0026] In this utility model, the upper mold 2 is connected to the lifting mechanism. When the mouse button is being molded, the lifting mechanism drives the upper mold 2 to descend. After the upper mold 2 and the lower mold 1 are fitted together, the mold is closed. At this time, the ejector rod 6 is flush with the bottom wall of the mold groove. The protrusion at the bottom of the upper mold 2 and the mold groove on the lower mold 1 form a complete mold cavity. Then, the injection molding material is injected into the mold cavity through the injection hole in the mold groove to complete the injection molding. After the material cools down, the mouse button can be molded and the demolding work can begin.

[0027] During demolding, the electric push rod 4 is first activated, which drives the lifting plate 5 to descend. After the lifting plate 5 descends, it drives the ejector rod 6 to descend. When the height of the top of the ejector rod 6 is lower than the left and right ends of the three-way pipe 8, the ejector rod 6 loses contact with the formed mouse button, thus completing the initial demolding. At the same time, the air pump 9 is turned on, and the air pump 9 inputs air into the two through holes 7 through the three-way pipe 8. After the air is injected into the through holes 7, it flows along the gap between the bottom of the formed mouse button and the mold groove and is discharged from the lower mold 1. During the process, the air can release the vacuum adsorption between the mouse button and the mold groove of the lower mold 1, thus completely achieving the demolding effect. The air pump 9 is turned off and the electric push rod 4 is turned on in the opposite direction. At this time, the lifting plate 5 will rise, and the ejector rod 6 will push the mouse button to rise. The mouse button will then move to the top of the lower mold 1, and the worker can then pick up the mouse button to complete the forming process of the mouse button.

[0028] Please see Figures 1-3 The lower mold 1 is equipped with a controller 10 on its front side. The controller 10 is used to control the opening and closing of the electric push rod 4 and the air pump 9. The top of the lifting plate 5 is fixedly connected to a distance sensor 11, and the output end of the distance sensor 11 is connected to the controller 10.

[0029] In this invention, the controller 10 facilitates the user's control over the electric push rod 4 and the air pump 9. The distance sensor 11 monitors the distance between the lifting plate 5 and the top wall of the cavity 3 in real time and displays it through the controller 10. This helps the worker determine the position of the lifting plate 5, which is beneficial for controlling the push rod 6 to move to the appropriate position, thereby improving the practicality of the device.

[0030] Please see Figures 1-3 The bottom of the lifting block 12 is fixedly connected to a limiting rod 13, and the top of the lower mold 1 is provided with a limiting hole 14 that matches the limiting rod 13.

[0031] In this invention, the limiting rod 13 and the limiting hole 14 can position the upper mold 2 and the lower mold 1 during the film closing process, effectively improving the film closing effect and enhancing the practicality of the device.

[0032] Please see Figures 1-3 The lifting block 12 is rotatably connected to a rotating plate 15 on its front side. A motor 16 is embedded in the front side of the lifting block 12. The input end of the motor 16 is connected to the controller 10. The output shaft of the motor 16 is fixedly connected to the rotating plate 15. A water tank 17 is installed on the front side of the rotating plate 15. A conduit 18 is connected to the bottom of the water tank 17. A water pump 19 is installed on the conduit 18. The input end of the water pump 19 is connected to the controller 10. A water box 20 is fixedly connected to the back side of the rotating plate 15. The bottom end of the conduit 18 passes through the rotating plate 15 and is connected to the water box 20. Spray nozzles 21 are installed at equal intervals on the top and bottom of the water box 20.

[0033] In this invention, before the molding begins, the user controls the motor 16 to rotate the rotating plate 15, and the water box 20 moves between the lower mold 1 and the upper mold 2. Then, the water pump 19 is turned on, and the water pump 19 extracts the water-based release agent from the water tank 17 and injects it into the water box 20. Then, the water-based release agent is sprayed from the nozzle 21 between the upper mold 2 and the lower mold 1, thereby achieving the effect of spraying the protrusion and mold groove with water-based release agent. After the spraying is completed and dried, the motor 16 is turned on in reverse to move the water box 20 to the right side of the lifting block 12. At this time, the mouse button can be molded. Due to the effect of the water-based release agent, the mouse button can be easily demolded, effectively reducing the difficulty of demolding, improving the demolding efficiency, and reducing the damage to the mouse button, thereby improving the practicality of the device.

[0034] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
