[0001] The invention relates to the technical field of mold processing, and in particular to a mold plane dimension detection device. Background Art

[0002] During the processing of the mold, strict dimensional inspection is required, from the external dimensions to the dimensions of the internal molding cavity, so as to maintain the dimensional standard of the workpiece when the workpiece is produced. However, the existing mold dimension inspection device used for mold processing still has some defects. It is not convenient to position the mold during the inspection, which makes the mold easy to offset and affect the inspection accuracy. It is also impossible to inspect the internal and external dimensions at the same time, and it is also impossible to inspect different internal depth positions according to the requirements. Therefore, a new type of mold dimension inspection device is needed to solve the above shortcomings.

[0003] Among them, a mold plane dimension detection device proposed in the prior art with authorization announcement number CN218034727U includes a bottom plate, a column is fixedly connected to one side of the top of the bottom plate, a cavity is arranged on one side inside the bottom plate, a lifting plate is arranged on the top of the bottom plate, a threaded shaft is movably connected to the inside of the cavity, the threaded shaft passes through one side of the bottom plate and extends to the outside of the bottom plate and is fixedly connected to a rotating handle, and a threaded sleeve is movably connected to the outside of the threaded shaft;

[0004] In the prior art, if the measuring equipment is measured in a non-horizontal state, it will cause certain errors in the measurement results. If the measuring device is not replaced in time after being used for a long time, it may cause errors in the measurement data. When fixing the object to be measured, the fixing device may cause damage to the object due to excessive fixing force. When more accurate values ​​need to be measured, it is impossible to achieve more accurate measurement data by replacing the scale. For this reason, we propose a mold plane dimension detection device. Summary of the invention
