When in use, the hydraulic cylinder 2 is started to push the upper mold 301 to move downward, and the limit block 304 will slide in the limit groove 302 to limit the upper mold 301. At the same time, the upper mold 301 squeezes the damper 305 to deform it, and converts part of the mechanical energy of the upper mold 301 pressing down into heat energy, thereby reducing the impact of the upper mold 301 on the lower mold 306. When the upper mold 301 and the lower mold 306 are closed, the damper 305 will be hidden in the through hole 303 and will not affect the closing of the mold. In this way, the vibration generated when the upper mold 301 and the lower mold 306 are closed is smaller, which can extend the service life of the mold.

[0027] Furthermore, the outer wall size of the lifting rod 703 is consistent with the inner wall size of the lifting groove 704, and multiple groups of lifting rods 703 are arranged on the upper surface of the fixed plate 702. Through the arrangement of the lifting rods 703 and the lifting grooves 704, when in use, the lifting rods 703 slide in the lifting grooves 704, and the lifting grooves 704 limit the lifting rods 703, making the movement of the lifting rods 703 more stable.

[0028] Working principle: The positioning column 5 will enter the positioning groove 4, and the positioning groove 4 will position the positioning column 5 to determine the positions of the upper mold base 1, the lower mold base 6 and the lower mold 306, making the installation of the mold more convenient and quick. After the installation is completed, the hydraulic cylinder 2 is started to push the upper mold 301 to move downward, and the limit block 304 will slide in the limit groove 302 to limit the upper mold 301. At the same time, the upper mold 301 squeezes the damper 305 to deform it, and converts part of the mechanical energy of the upper mold 301 into heat energy, reducing the impact of the upper mold 301 on the lower mold 306. The upper mold 301 and the lower mold When the upper mold 301 and the lower mold 306 are closed, the damper 305 will be hidden in the through hole 303 and will not affect the closing of the mold. In this way, the vibration generated when the upper mold 301 and the lower mold 306 are closed is smaller, which can extend the service life of the mold. After the injection molding is completed and the molding is cooled, the cylinder 701 is started to push the fixed plate 702 and the lifting rod 703 to rise. The lifting rod 703 slides in the lifting groove 704. The lifting groove 704 limits the lifting rod 703 to make the movement of the lifting rod 703 more stable. The lifting rod 703 ejects the cooled and finalized product, demolds the product and the lower mold 306, and improves work efficiency.
