Description

Technical Field

[0002] A mold base usually refers to the starting prototype or basis for making a mold or model. It can be an original model for making casting molds, injection molds, die-casting molds, etc. These mold bases can be made of wood, metal, plastic or other materials and are used as models for replication when making molds.

[0003] Most of the existing mold base processing devices are for one-time processing, that is, after the parts are fixed and the processing origin is determined, the processing begins directly and ends after the parts are formed. The position of the parts cannot be changed before the current processing step is completed. However, when processing the mold base, the positioning device mostly positions the two sides of the mold base. During the processing, the mold base can easily slide in another direction, affecting the processing of the mold base. For this reason, we propose a positioning device for mold base processing.
