Description

Technical Field

[0001] The utility model relates to the technical field of scissor foot manufacturing molds, and more specifically, the utility model relates to a keyboard scissor foot manufacturing mold with a stable structure. Background Art

[0002] A keyboard scissor foot manufacturing mold is a special tool for producing keyboard parts with a scissor foot structure. The design and manufacture of such a mold are crucial for ensuring the high precision, high quality, and production efficiency of the keyboard scissor feet. The keyboard scissor foot manufacturing mold usually consists of an upper mold core and a lower mold core, which are spliced to form a cavity for molding the outer shear. The mold also includes ejector pins that penetrate the lower mold core upward and are used to eject the outer shear in the cavity after molding. In addition, the mold includes two symmetrically arranged inclined pins on the left and right. The upper ends of the inclined pins are located within the mounting holes for installing the inner shear of the outer shear, and the upper ends of the two inclined pins are close to each other, so that the two inclined pins are inclined in the vertical direction. The upper end of the inclined pin has a forming step that cooperates with the outer shear slot on one side of the inner wall of the outer shear for forming the slot of the outer shear.

[0003] The existing keyboard scissor foot manufacturing molds do not have a structural strengthening structure. A mold lacking a strengthening structure is prone to deformation or damage when subjected to the pressure and impact during the molding process, resulting in a shortened service life of the mold. This will increase the frequency of mold repair and replacement and raise the production cost. The deformation or damage of the mold will cause the size and shape of the produced keyboard scissor feet to be unstable, affecting the overall quality of the product. Problems such as dimensional deviation, irregular shape, and uneven surface may occur, affecting the use performance and user experience of the keyboard. Therefore, we propose a keyboard scissor foot manufacturing mold with a stable structure. Content of the Utility Model

Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0019] Such as Figures 1 to 4As shown in the figure, the utility model provides a keyboard scissor foot manufacturing die with a stable structure, which includes a groove body 1. Support columns 2 are fixedly installed at the four corners of the bottom of the groove body 1. A die 3 is arranged in the groove body 1. Reinforcing rods 4 are fixedly installed on the outer sides of the die 3. A bracket 5 is fixedly installed in the groove body 1. The bracket 5 and the reinforcing rods 4 are detachably connected by screws. The die 3 is located above the bracket 5. A top plate 6 is arranged in the groove body 1. The top plate 6 is located below the die 3. The top plate 6 can block the lower port of the die 3. The top plate 6 can move into the die 3. Guide rods 7 are fixedly installed at the four corners of the top plate 6. The lower ends of the guide rods 7 penetrate through the bracket 5. A rack 8 is fixedly installed at the center of the bottom of the top plate 6. A driving wheel 9 is rotatably installed in the groove body 1. The driving wheel 9 meshes with the rack 8. A servo motor 10 is fixedly installed in the groove body 1. An output shaft end of the servo motor 10 is fixedly installed with an incomplete gear 11. The incomplete gear 11 meshes with the driving wheel 9.

[0020] Among them, as Figure 2 shown, both the top plate 6 and the rack 8 are hollow inside. The inner cavities of the top plate 6 and the rack 8 are in a communicating state. A pump body 12 is fixedly installed at the bottom of the groove body 1. A drainage end of the pump body 12 is communicated with and fixedly installed with a telescopic pipe 13. The upper end of the telescopic pipe 13 is fixedly connected to the bottom of the rack 8 and communicated with the inner cavity of the rack 8. The pump body 12 introduces low-temperature coolant into the inner cavity of the rack 8 through the telescopic pipe 13. A dust-proof cover is installed on the servo motor 10. During the cooling process, the low-temperature coolant enters the top plate 6, thereby cooling the workpiece in the die and improving the cooling efficiency.

[0021] Among them, as Figure 3 and Figure 4 shown, side ports 14 are opened on both sides of the groove body 1. Vibration mechanisms are arranged in the side ports 14. The vibration mechanisms can impact on the bracket 5. The vibration mechanism includes a sleeve 15. The sleeve 15 is fixedly installed in the side port 14. A push rod 16 is inserted into the sleeve 15. One end of the push rod 16 extends to the bracket 5. A spring 17 is fixedly connected in the sleeve 15. The other end of the spring 17 is fixedly connected to the push rod 16. The push rod 16 is made of metal iron. An electromagnet 18 is fixedly installed in the sleeve 15. The electromagnet 18 is located on one side of the push rod 16. During the demoulding process, the electromagnet 18 is energized and attracts the push rod 16. The push rod 16 moves to one side. The electromagnet 18 is powered off. The push rod 16 resets under the elastic force of the spring 17 and impacts on the bracket 5, thereby causing the die to vibrate and assisting in the separation of the workpiece from the die.

[0022] The working principle and usage process of the present utility model: By arranging a plurality of reinforcing bars 4 on the side of the mold 3, the structural strength of the mold 3 is improved. The arrangement of the reinforcing bars 4 can effectively enhance the resistance of the mold when subjected to external pressure and impact, thereby reducing the risk of deformation or damage of the mold caused by uneven stress. Especially during the molding process, the mold needs to withstand greater pressure and impact force. The arrangement of the reinforcing bar 3 can ensure the stability and durability of the mold. After the strength of the mold is improved, its service life will be correspondingly extended. This can not only reduce the maintenance and replacement frequency of the mold, lower the production cost, but also improve the production efficiency and reduce the production interruption and downtime. The arrangement of the reinforcing bar 3 can ensure the stability and consistency of the mold during the molding process, thereby producing keyboard scissors feet with more stable and consistent dimensions, shapes, and surface qualities.

[0023] During the demolding process, the servo motor 10 drives the incomplete gear 11 to rotate. The incomplete gear 11 drives the driving wheel 9 to rotate, and the driving wheel 9 drives the rack 8 to move, thereby driving the top plate 6 to move upward and push the workpiece in the mold 3, so that the workpiece quickly detaches from the mold 3, effectively improving the demolding efficiency.
