[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the design limitation of the above locking device is that it is only applicable to mechanical molds of a specific proportion and lacks adaptability to molds of different sizes, so the scope of use in practical applications is limited. In view of this, we propose a mechanical locking mechanism for mechanical molds. Utility Model Content

[0006] The purpose of the utility model is to provide a mechanical locking mechanism for a mechanical mold to solve the problems raised in the above background technology.
