The protruding structure is equipped with at least one main ejector cylinder and at least two auxiliary ejector cylinders, the stroke of the main ejector cylinder being greater than the stroke of the auxiliary ejector cylinders. An ejector guide plate is provided between the mold plate body and the protruding structure. The piston rod of the main ejector cylinder is connected to the ejector guide plate, while the piston rod of the auxiliary ejector cylinders is not connected to the ejector guide plate. Several ejector rods are provided on the ejector guide plate, penetrating the mold plate body. During the stroke of the auxiliary ejector cylinders, the main ejector cylinder and the auxiliary ejector cylinders together drive the ejector guide plate to complete the ejection action of the ejector rods. During the remaining stroke, the main ejector cylinder alone drives the ejector guide plate to complete the ejection action of the ejector rods. This mold closing mechanism with a composite ejector cylinder can provide a large ejector force in the initial demolding stage and achieve rapid ejection in subsequent strokes, combining large ejection force and high movement speed to improve production efficiency.

The utility model relates to the technical field of winding devices, and discloses an embedded sealing strip winding device which comprises a frame body, the inner wall of the frame body is rotationally connected with a guide roller, the side wall of the guide roller is rotationally connected with a transmission rod, and the inner wall of the frame body is provided with a winding assembly. According to the embedded sealing strip winding device, before being wound by the winding roller, the sealing strip passes through the guide groove and the guide path to be tightly attached to the section contour of the sealing strip, the sealing strip is forced to keep a correct posture, winding deformation or indentation caused by abnormal posture is prevented, opposite movement of the clamping plates is prevented, and then the device is matched with sealing strips of different sizes; the device is suitable for sealing strips with different widths and heights, the positions of the sealing strips can be stabilized in the guiding process after the clamping plates clamp the sealing strips, the sealing strips are prevented from deviating or inclining in the high-speed movement process, the lower pressing plate provides continuous and stable pressing force, the sealing strips are prevented from being loosened, and the shape of the rolled sealing strips is kept compact and stable.

This invention discloses a construction method for controlling the construction alignment and overturning resistance of a type A cable tower, comprising the following steps: preliminary preparation; design, verification, and evaluation of the cable tower's anti-overturning combined control system, which includes a cable tower hollow column construction alignment combined control system formed by connecting the tower column stiffening frame system and the anti-overturning system, a multi-level horizontal active cross bracing system, and a prestressed concrete upper crossbeam system. This system resists the overturning force generated by the upward suspended construction of the hollow tower column through the cable tower hollow column construction alignment combined control system. Combined with the synergistic effect of the horizontal active cross bracing system and the prestressed concrete upper crossbeam system, it jointly offsets the inward tilting force generated by the self-weight and construction load of the two limb tower columns during construction, thereby balancing the tower column overturning moment and ensuring that the cable tower alignment, inward tilting force, and tilt angle meet design requirements. The method also includes the following steps: dynamic control analysis of the spatial position of the cable tower column construction segments; construction and dismantling of the cable tower anti-overturning combined control system.
