[0001] The invention relates to the technical field of forming moulds, in particular to a combined subway shield segment forming mould. Background Art

[0002] The subway shield segment is the main assembly component of the shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads.

[0003] The subway shield segments are mainly made of high-strength impermeable concrete, and are formed by using finished segment molds after sealing and pouring concrete; however, the prior art has the following deficiencies: First, when concrete is poured into the segment forming mold, after the concrete in the segment forming mold solidifies, most of the segment forming molds cannot be removed, so it is inconvenient for workers to take the formed concrete out of the segment forming mold, which is time-consuming and laborious; Second, after the subway shield segments are formed, natural cooling is usually adopted, and then they are demolded, which results in a slow cooling speed, thereby reducing the processing efficiency of the subway shield segments; Therefore, the present invention provides a combined subway shield segment forming mold to solve the above problems.

[0016] The present invention provides a combined subway shield segment forming die, which has the following beneficial effects:

[0017] (1) The present invention arranges the push rod, hydraulic cylinder, and push rod components inside the automatic unloading structure, so that when the upper mold box body moves, the movable cross plate moves upward, so that the push rod pushes the finished product out. In this way, the push rod pushes the finished product out of the mold under the action of the telescopic spring, completing automatic demolding. Automatic demolding can greatly reduce the production cycle and can quickly release the mold after the subway shield segment is formed, so that the next round of pouring can start immediately. This rapid mold release can significantly improve the overall efficiency of the production line.

[0018] (2) The present invention arranges components such as a cooling ring, a cooling water tank and a seesaw plate inside the cooling structure, so that when the upper mold box body is pressed down for casting, the cooling ring will be pushed into the annular groove through the seesaw plate, so that the liquid inside the cooling ring will cool the concrete in the mold and accelerate the molding speed. Through proper cooling, it can be ensured that the concrete is completely cured and solidified in the mold, thereby ensuring the shape and dimensional accuracy of the molded subway shield segment.

[0019] (3) The present invention controls the arrangement of components such as the sliding plate, rack and gear inside the liquid outlet structure. When demolding, the force of the rack and gear is transmitted to push the sliding plate to block the liquid inlet. When pouring, the sliding plate is pulled to open the liquid inlet. This can prevent the liquid plastic from being in the flow channel mold during demolding, which will not only waste resources, but also affect the next pouring and reduce the quality of the finished product.

[0032] Among them, the automatic unloading structure 7 includes a fixed platform 71 and a sliding column 75. The side of the fixed platform 71 is fixedly connected to the side of the lower mold box body 1. A telescopic spring 72 is fixedly connected to one side of the fixed platform 71. The end of the telescopic spring 72 away from the fixed platform 71 is fixedly connected to a pushing rod 73. A movable groove 74 is opened on the top of the fixed platform 71. The sliding column 75 runs through the top of the lower mold box body 1 and is slidably connected to the lower mold box body 1. A movable cross plate 76 is fixedly connected to the bottom of the sliding column 75. A support plate 77 is fixedly connected to the inner wall of the lower mold box body 1. A hydraulic cylinder 78 is fixedly connected to the top of the support plate 77. A force rod 79 is arranged on the top of the hydraulic cylinder 78, and a hydraulic rod 710 is arranged on the side of the hydraulic cylinder 78.

[0033] A push rod 711 is fixedly connected to the top of the movable cross plate 76. The push rod 711 penetrates the bottom of the lower mold 5 and is slidably connected to the lower mold 5. A movable plate 713 is fixedly connected to the bottom of the push rod 73. The movable plate 713 is slidably connected to the inner wall of the movable groove 74. A protective pad 712 is provided on the side of the push rod 73. The top of the sliding column 75 is fixedly connected to the bottom of the upper mold box body 2.

A vertical plate 811 is fixedly connected to the top of the seesaw 810, and an L-shaped plate 812 is fixedly connected to the side of the movable horizontal plate 76. The design of the return spring 89 can allow the seesaw 810 to return to its original position, thereby working better.

[0039] The water inlet pipe 87 and the water outlet pipe 88 are set to be made of rubber material. The seesaw 810 is located directly below the L-shaped plate 812, and the top of the seesaw 810 is located on the displacement track of the bottom of the L-shaped plate 812.

When the push rod 73 moves backward, the guide force The rod 97 pulls a sliding plate 92. At this time, the movement of the sliding plate 92 will move the rack 94 on the same side. The movement of the rack 94 will cause the gear 95 to rotate, thereby pushing the rack 94 on the other side. In this way, the rack 94 on the other side will also pull the sliding plate 92 outward, thereby opening the liquid inlet 4. When the push rod 73 moves toward the inside of the mold, it will push a sliding plate 92 through the guide rod 97. The movement of the sliding plate 92 will also move the rack 94 on the same side.
