In addition, the processing precision of automotive parts is relatively high, and the requirements for automotive molds are also relatively higher.

[0003] At present, in order to ensure the accuracy of the combination of the upper and lower molds of an automobile, a positioning device is usually used to position the upper and lower molds of the automobile. However, the existing molds still have some shortcomings when used. For example, when the upper and lower molds of the automobile are closed, the existing positioning device lacks a prompt to indicate whether the upper and lower molds are closed in place, and it is impossible to intuitively understand whether the upper and lower molds are closed in place. At the same time, when the upper and lower molds are misaligned, it cannot be discovered in time, resulting in the production of defective products. Based on this, an automobile mold positioning device is proposed to solve the above problems. Utility Model Content
