[0002] Injection molds usually use melted plastic liquid to inject into the mold cavity, and the plastic liquid is formed according to the internal cavity shape of the mold. However, since the current injection molds need time to cool and set after injecting the melted plastic liquid, the upper and lower molds are prone to fall off and separation during the cooling process, which can easily cause the product to be deformed or damaged due to insufficient cooling and setting, increase the product scrap rate, and easily produce defective products. Therefore, it is necessary to use a locking mechanism to lock the injection mold during the cooling and setting period to ensure that the injection mold does not fall off;

[0003] It takes a long time to put the existing injection mold into the existing locking mechanism, and it is necessary to quickly enter the locking mechanism to avoid scalding workers. Therefore, the existing technology needs to be improved. Utility Model Content
