Technical Field

[0001] This utility model applies to the technical field of product molds, and particularly relates to a multi-module quick-change keyboard cover mold. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products typically use rubber injection molding and plastic injection molding, often used for complex products such as mouse shells and keyboard covers. With the continuous development of technology, electronic products are becoming increasingly functional. For example, keyboards have evolved from simple typing functions to integrate various lighting and control modules. Therefore, the shape and specifications of keyboard covers vary. Traditionally, different versions of keyboard covers require different front and rear molds, necessitating a changeover after each version is completed. This results in high production costs, long molding times, and the need for dedicated storage space for the molds, making it unsuitable for small production workshops. Furthermore, switching between different product versions requires disassembling and replacing the entire mold, leading to low changeover efficiency. If a simple, interchangeable multi-module quick-change keyboard cover mold could be designed, these problems could be solved. Utility Model Content

[0017] like Figures 1 to 6As shown, in this embodiment, the present invention includes an upper mold 1 and a lower mold 2. The upper mold 1 is provided with a first interchangeable part 3, a second interchangeable part 4, and a third interchangeable part 5. The lower mold 2 is provided with a fourth interchangeable part 6, a fifth interchangeable part 7, and a sixth interchangeable part 8. The first interchangeable part 3, the second interchangeable part 4, and the third interchangeable part 5 respectively cooperate with the fourth interchangeable part 6, the fifth interchangeable part 7, and the sixth interchangeable part 8. The upper end face of the upper mold 1 is provided with a plurality of injection ports 9, which are connected to the injection channel formed by the injection groove of the upper mold 1 and the injection groove of the lower mold 2. Therefore, by using a set of upper and lower molds and multiple sets of interchangeable parts, adaptation to multiple different feature positions of the keyboard cover can be achieved, enabling on-machine mold changes. The structure is simple, the changeover efficiency is high, and the adaptability is strong.

[0018] like Figure 3 and Figure 5 As shown, in this embodiment, the upper mold 1 is provided with a plurality of upper mold interchangeable component mounting slots 10. The first interchangeable component 3, the second interchangeable component 4, and the third interchangeable component 5 are respectively connected to the corresponding upper mold interchangeable component mounting slots 10 by a plurality of first screws 11. The first interchangeable component 3, the second interchangeable component 4, and the third interchangeable component 5 cooperate with the corresponding injection positions of the injection molding groove of the upper mold 1. Thus, the interchangeable components are stably connected to the upper mold by the first screws 11, ensuring the sealing of the injection molding process.

[0019] like Figure 4 and Figure 6 As shown, in this embodiment, the lower mold 2 is provided with a plurality of lower mold interchangeable component mounting slots 12. The fourth interchangeable component 6, the fifth interchangeable component 7, and the sixth interchangeable component 8 are respectively connected to the corresponding lower mold interchangeable component mounting slots 12 by a plurality of second screws 13. The fourth interchangeable component 6, the fifth interchangeable component 7, and the sixth interchangeable component 8 cooperate with the corresponding injection positions of the injection molding groove of the lower mold 2. Thus, the interchangeable components are stably connected to the upper mold by the second screws 13, ensuring the sealing of the injection molding process.

[0020] like Figure 5 and Figure 6 As shown in this embodiment, both the first screw 11 and the second screw 13 have a leak-proof sealing layer on their outer locking ends. Therefore, the sealing screws effectively prevent material leakage during injection molding, which could damage interchangeable parts.

[0021] like Figures 2 to 4As shown, in this embodiment, the upper surface of the lower mold 2 is provided with a plurality of positioning blocks 14, and the lower surface of the upper mold 1 is provided with a plurality of limiting grooves 15.
