This utility model discloses a mold inspection device for rubber mold manufacturing. The key technical features include a base plate; a movable adjustment component is disposed on the upper surface of the base plate; a support seat is mounted on the upper surface of the movable adjustment component; a guide rod cylinder is mounted on the upper surface of the support seat; and a vacuum suction cup is mounted on the upper surface of the guide rod cylinder. A rubber mold body is adsorbed and disposed on the upper surface of the vacuum suction cup. The height adjustment of the rubber mold body by the guide rod cylinder enables the mold inspection equipment to measure and inspect rubber mold bodies of different specifications at accurate positions, thereby significantly improving the reliability and
repeatability of the inspection results. Simultaneously, the precise adjustment of the movable adjustment component ensures that the mold maintains a consistent trajectory and position during movement, while the vacuum suction cup firmly and accurately fixes the rubber mold body, avoiding positioning errors caused by loosening or displacement, thus ensuring that each mold can be evaluated according to strict quality standards.
