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 novel transmission line river-crossing tower foundation relates to transmission line engineering technical field, it includes four independent foundation and three layers of link beam, three layers of link beam are arranged at four independent foundation between along vertical direction interval, for the whole reinforcement of four independent foundation and the stress synergy, every independent foundation all includes foundation bottom plate and foundation stand, and foundation bottom plate horizontal arrangement, its top and the bottom fixed connection of foundation stand, three layers of link beam include upper layer link beam, middle layer link beam and lower layer link beam, upper layer link beam is close to the bottom setting of iron tower tower leg, and middle layer link beam sets up in the middle position of foundation stand height direction, and the bottom of lower layer link beam is flush with the top of foundation bottom plate. The utility model scheme can adapt to the soft soil of river bank, and the whole stress synergy performance is good, can effectively resist water environment erosion, and the service life is long.

The application relates to a semi-assembled RPC-PC bundle shear wall combined structure which comprises a lower end beam, a shear column and an upper end beam. The two ends of the shear column are fixedly connected with the lower end beam and the upper end beam respectively; the shear column comprises an active powder concrete outer mold and ordinary concrete filled in the internal space of the active powder concrete outer mold. The RPC-PC bundle shear wall utilizes the material advantages of RPC, can improve the stress performance and the anti-seismic performance of the shear wall, and can also improve the fire resistance, impact resistance and corrosion resistance of the shear wall. On the other hand, the RPC is prefabricated into the outer mold plate of the shear wall to form the RPC-PC bundle shear wall outer mold. The combined form can save a large amount of wood mold plates and steel mold plates, has a small influence on the surrounding environment, improves the work efficiency, can reduce the maintenance cost in the later period, and has a wide engineering application prospect.
