This utility model provides a mold that utilizes the mold opening force of an injection molding machine to drive the ejection mechanism of the molded product. It relates to the field of mold technology and includes a movable side, a fixed side, an ejection mechanism, and a driving mechanism. The driving mechanism includes a pull plate, a rocker arm, a guide structure, and a rotating shaft. The pull plate is installed on the movable side, and the rocker arm is connected to the ejection mechanism via the rotating shaft. A guide pin guides the rocker arm. Both the pull plate and the rocker arm are equipped with hook structures. This design, by using a driving mechanism composed of a pull plate, rocker arm, guide structure, and rotating shaft, offers a simple and reliable structure with minimal installation space, reducing mold and injection molding costs. After the mold completes the ejection action, the rocker arm can disengage from the pull plate, allowing the movable side to continue performing larger mold opening actions, meeting the needs of a robotic arm to enter the mold and remove the product. The mold opening stroke is not affected by the mold thickness.

The utility model discloses a kind of six-prong block solid stone slope protection structures, including multiple six-prong blocks, multiple six-prong blocks inside are provided with up and down through grass planting cavity;Multiple six-prong blocks are provided with at least 6 through holes at height direction 1 / 3 along horizontal direction through;Multiple through hole is through with steel wire A and steel wire B reinforcement fixed;Multiple six-prong blocks are laid along box culvert boundary boundary line and cut-off flood drainage channel top boundary line respectively, six-prong block inside located in edge area is filled with concrete by concrete filling cavity, to form boundary reinforcement area.The six-prong block solid stone slope protection structure of the utility model not only improves the structural stability and ecological performance of slope protection, also has the advantages such as convenient construction, cost benefit is high, durability is strong and water permeability is good.
