[0002] A plastic mold is a tool used to make plastic products. It is mainly used in the plastic processing industry and is used in conjunction with a plastic molding machine to give plastic products a complete configuration and precise size. A plastic mold injects liquid or semi-solid plastic into the mold cavity, and after the plastic cools and hardens, a plastic product with the same shape as the mold cavity is formed.

[0003] When manufacturing plastic products, different molds are usually replaced in order to manufacture different plastic products. Since different molds have different lengths and widths, and plastic molds require matching fixing devices for use, it is necessary to adjust the size of the fixing devices. However, most of the current mold fixing devices cannot adjust the length and width at the same time, resulting in the fixing device being able to only fix two surfaces of the mold, making it difficult to achieve effective fixation, which in turn leads to a decrease in the accuracy of the mold.
