Description

Technical Field

[0001] The utility model relates to the technical field of plastic shell deformation correction, in particular to a computer keyboard plastic shell deformation correction device. Background Art

[0002] The plastic shell of a computer keyboard is an indispensable part of the keyboard design. It undertakes the important functions of protecting internal components, providing support and fixation, and enhancing user experience. It is made of wear-resistant and impact-resistant plastic materials. Plastic shells with complex shapes and structures are manufactured through injection molding and other processes, which not only ensures the durability and stability of the keyboard, but also provides a comfortable feel and touch.

[0003] Since the plastic material itself has a certain shrinkage rate and thermal stability, after injection molding, due to the inherent characteristics of the plastic, the plastic shell will shrink to a certain extent. This shrinkage may cause the size of the shell to be slightly reduced or deformed, resulting in deformation and distortion of the plastic shell of the computer keyboard after production, which affects the assembly of the keyboard and the user experience of later users. Therefore, the plastic shell of the computer keyboard needs to be corrected after production.

[0004] However, most of the existing correction devices correct the plastic shell of the computer keyboard by hot pressing. However, after the plastic shell is corrected, it may be deformed again due to forces in different directions and cooling shrinkage of the plastic when it is taken out, resulting in repeated correction. Waiting for the coolant of the corrected plastic shell is time-consuming. In order to solve the above problems, while the computer keyboard plastic shell is corrected by hot processing, the corrected computer keyboard plastic shell can be quickly cooled and shaped, thereby avoiding repeated deformation, improving the correction efficiency and saving cooling time. For this reason, we propose a computer keyboard plastic shell deformation correction device. Utility Model Content

[0037] Instructions

[0038] When in use, firstly, the plastic shell to be corrected is clamped and installed between the two groups of placement clamps 13, and then the halogen tube 11 is started for heating. When the halogen tube 11 is heated, the heat is transferred from the protective sleeve 12 to the inside of the installation box 10 through conduction, thereby softening the plastic shell placed between the two groups of placement clamps 13, and then the mounting plate 5 is driven downward by starting the hydraulic cylinder 4, thereby driving the installation box 10 fixedly installed on the bottom of the mounting plate 5 to be pressed down together with it until the plastic shell contacts the correction groove 6 opened on the top of the correction disk 2, and the plastic shell is gradually matched with the correction groove 6 by pressing down the installation box 10, thereby completing the shaping correction. After the shaping is completed, the interior of the protective sleeve 12 can be injected through the connection between the connecting tube 15 and the sealing port 16. Water flows into the correction disk 2, thereby replacing the heat on the correction disk 2 through heat conduction, thereby accelerating the cooling of the plastic shell and avoiding secondary deformation due to the cooling and shrinkage of the plastic after it is removed. In addition, through the arrangement of the mounting seat 7, the clamping piece 8 and the clamping groove 9, when correcting and repairing plastic shells at different positions, the limit on the correction disk 2 can be released by pulling out the clamping piece 8, thereby replacing the correction template with the same shape as the correction required, and correcting and repairing it.
