Description

Technical Field

[0001] The utility model relates to the field of clamping, in particular to an efficient side mold opening and closing device for a segment mold. Background Art

[0002] The production of shield segments requires the use of customized segment molds. The segment mold is composed of a middle mold, side molds, and end molds. The side molds and end molds are fixed to the middle mold by hinges and are a component on the mold as a device for opening and closing the mold. During the production of segments, the side molds and end molds often need to be opened. Due to the certain weight of the side molds and end molds, the mechanical principle of a right- and left-handed screw is used to rotate the screw to achieve the purpose of opening the mold during mold opening, or directly the strength of the on-site operator's arm is used to open the mold. However, when the screw is damaged or the operator's strength is insufficient, it may cause the operator to sprain, having a certain safety hazard.

[0003] The prior art 201920867789.9 discloses an automatic opening and closing device for the end and side molds of a segment mold. Although it solves the above problems, it cannot drive the mold to close during mold closing and still requires manual operation, not only increasing labor but also possibly having a safety hazard of false operation.

[0019] Furthermore, the two telescopic driving devices 712 are hydraulic cylinders, which not only have strong load-bearing capacity but also are small in size.

[0020] Furthermore, a telescopic plate 9 is telescopically arranged between the two driving push plates 711 to ensure simultaneous lifting and lowering.

[0021] When in use: when the mold needs to be opened, first start the two hydraulic cylinders, the output ends of the two hydraulic cylinders respectively drive the two driving push plates 711 to move toward the six levers 6, the two driving push plates 711 drive the six hook plates 716 to move toward the through holes 8 of the multiple levers 6, the two driving push plates 711 move with the four guide plates 721, and then the four guide plates 721 move to drive the guide pulley 724 to move in the guide slide 723, when the guide pulley 724 moves to the guide slide 723 and tilts to a certain entrance, one end of the hook of the six hook plates 716 completely penetrates the through holes on the six levers 6 8, then the guide pulley 724 enters the guide slide 723 and tilts for a while, then drives the guide plate to move toward the middle of the trolley, and then the four guide plates 721 respectively drive the two driving push plates 711 to move closer to each other, and then the two driving push plates 711 drive the six claw plates 716 to move toward one side of the through hole 8 of the six levers 6, so that one end of the claws of the six claw plates 716 can hook the six levers 6, and when the guide pulley 724 leaves the guide slide 723 and tilts for a while, it starts to move vertically again, and then the two driving push plates 711 move vertically upward again. During this period, the two driving push plates 711 start Finally, one end of the six levers 6 is driven to tilt upward, and there is enough space between one end plate of the hook claw of the six hook claw plates 716 and the two driving push plates 711 for one end of the six levers 6 to tilt upward. Since one end of the six levers 6 tilts upward, one end drives the end surface and the side mold 5 of the pipe segment mold to flip outward, thereby realizing the opening of the pipe segment mold. When the mold needs to be closed, the hydraulic cylinder is reset, and then the two driving push plates 711 drive the six hook claw plates 716 to move downward, and the six hook claw plates 716 move one end of the six levers 6 downward, and then the four guide plates 721 move downward, and the four guide plates 721 drive the four The guide pulley 724 moves downward along the guide slide 723. When the guide slide of the moving track tilts for a section, the two driving push plates 711 and the six hook plates 716 move toward the two ends of the trolley, and the six hook plates 716 slowly move toward the middle of the through hole 8. At this time, one end of the hook of the six hook plates 716 is still hooked on one end of the six levers 6. When the guide pulley 724 completely disengages from the guide slide and tilts for a section, the six hook plates 716 move to the middle of the through hole 8 and do not contact one end of the six levers 6. At this time, the six levers 6 also drive the end face and the side mold 5 to close with the middle mold 3, and then the worker only needs to tighten the bolts.

[0022] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
