However, the core replacement process is complex and cumbersome, failing to improve work efficiency. Therefore, this precision mold facilitates core replacement. The cumbersome design does not improve work efficiency. Therefore, a precision mold that facilitates mold core replacement is proposed. During use, the top mold core can be quickly pulled out from the mold core fixing groove by pulling the handle for rapid replacement. Then, the bottom mold core can be quickly pushed out of the mold core fixing groove for replacement. This effectively improves the efficiency of mold replacement when needed.
