The keyboard is usually made of plastic, which has the characteristics of corrosion resistance, low manufacturing cost, durability, and easy shaping. Plastic keyboards are usually made using injection molding devices. After the traditional injection mold is used to inject the plastic keyboard, the plastic keyboard needs to be cooled so that the plastic keyboard can be quickly formed.

[0003] For example, the prior art publication number is CN216968505U, an integrated injection-molded keyboard mold. The utility model uses two gaskets to form a soft rubber convex body of the key in the middle of the gasket, and pressing the soft rubber convex body can directly transmit the pressing pressure from the upper end, so that the pressing accuracy is improved, and during the keyboard injection molding process, the injection-molded keyboard will be quickly cooled, thereby increasing the keyboard molding speed. Opening the upper and lower pressure plates can make the keyboard quickly demolded, convenient and quick.

[0004] However, the above-mentioned prior art still has the following problems when used: most of the existing plastic keyboard injection molds are cooled by air cooling or low-temperature water cooling. The air cooling method has low cooling efficiency and poor effect, which is not conducive to rapid production and preparation. Although the low-temperature water cooling method improves the cooling effect, the high-temperature plastic keyboard is prone to cracking due to the temperature difference when encountering low-temperature water. Based on this, the utility model provides a plastic keyboard key integrated injection mold that uses air cooling and water cooling to cool down. Utility Model Content
