Description

Technical Field

[0001] The utility model belongs to the field of railing shields, and in particular relates to a steel mold for railing shields. Background Art

[0002] As we all know, the high-speed rail shield is a protective device installed on both sides of the high-speed railway. By using this device, the inside and outside of the high-speed railway can be isolated, which is beneficial to the protection of the high-speed railway. At the same time, it can also reduce the external transmission of high-speed rail noise and reduce noise pollution along the high-speed railway.

[0003] The existing technology has specially developed some railing shield steel molds. For example, the Chinese patent with the announcement number "CN210999240U" announced "A quick-detachable railing shield mold", which can flip and flatten the baffles on three sides by folding in half. The utility model also arranges a quick clamping module between the right baffle and the front baffle and the rear baffle, and the various parts can be fixed by the quick clamping module when prefabricating the concrete railing shield; furthermore, the utility model inserts a middle baffle into the gap to realize the molding of the middle part of the railing shield. The utility model has a novel structural design and is easy to use. The overall structure is fixed without bolts, and the prefabrication of the railing shield can be quickly realized, which greatly improves the production efficiency and precision compared with the existing molds; furthermore, the utility model avoids the use of bolts, which can further reduce the production cost, and is an ideal quick-detachable railing shield mold.

[0004] Although a middle baffle is inserted into the gap to achieve the molding of the middle part of the railing shield, the structural design of this utility model is novel, easy to use, and the overall structure is fixed without bolts, but when demolding, the shield is often damaged due to excessive demolding force, which requires re-canning and cannot be effectively and safely removed. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a steel mold for a railing shield to solve the problem of the railing shield.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A steel mold for a railing screen comprises a base, wherein a front plate, a side plate and a rear plate are hingedly connected to the outer sides of the base on all four sides, a rotating plate is rotatably installed inside the side of the base close to the rear plate, and a movable plate is slidably installed inside the base, two fixed blocks are fixedly installed on both sides of the ends of the front plate and the rear plate away from the base, a rotating shaft is rotatably installed inside the fixed blocks, and a square rod is fixedly installed on the outer ring of the rotating shaft, and a clamping block is fixedly installed on both sides of the end of the side plate away from the base, the square rod is clamped in the inside of the clamping block, and a fixing column is fixedly installed on the end of the square rod away from the rotating shaft, the fixing column is clamped on one side of the clamping block, and a plug plate is slidably installed at the center position of the side plate.

[0008] As a preferred technical solution, a rectangular groove is provided inside the base, sliding grooves are provided on both sides of the rectangular groove, and cylindrical rods are fixedly installed inside the sliding grooves.

[0009] As an optimal technical solution, limiting rods are fixedly installed on both sides of the bottom of the movable plate, and the limiting rods are slidably installed inside the sliding groove at one end away from the movable plate, and the limiting rods are slidably installed inside the outer ring of the cylindrical rod at one end away from the movable plate.

[0010] As an optimal technical solution, a mounting groove is provided at the bottom of the rectangular groove, a first bevel gear is rotatably mounted at the bottom of the mounting groove, a second bevel gear is fixedly mounted at one end of the rotating plate, and the first bevel gear and the second bevel gear are meshed with each other.

[0011] As an optimal technical solution, a threaded rod is fixedly installed on the upper end of the first bevel gear, the outer ring of the threaded rod is threadedly connected to a threaded pipe, and a fixing bracket is fixedly installed on the end of the threaded pipe away from the threaded rod, and the fixing bracket is fixedly installed on the bottom of the movable plate.

[0012] As an optimal technical solution, the rectangular groove is integrally formed with raised blocks on both sides of the installation groove, and a limiting groove is provided inside the raised block. The outer ring of the end of the threaded tube away from the fixed frame is integrally formed with two stabilizing rods, and the stabilizing rods are slidably installed inside the limiting groove.

[0013] As an optimal technical solution, a plurality of hinge grooves are provided around the base, a plurality of hinge rods are rotatably installed inside the hinge grooves, a rear plate, a side plate and a front plate are fixedly installed on the upper ends of the hinge rods, a plug-in groove is provided at the center of the side plate, and the plug-in plate is slidably installed inside the side plates on both sides through the plug-in groove.

[0014] In summary, the present invention has the following beneficial effects:

[0015] First, workers can assemble the front panel, side panel and back panel hinged around the base together and effectively install the plug panel between the side panels, thus forming a model of the shield panel and then injecting cement into the mold, which can effectively make the shield panel. Since the front panel, side panel and back panel are assembled together through a structure that can be quickly assembled and disassembled during assembly, the effect of shield panel molding can be effectively improved, and the efficiency of production can be improved. During assembly, workers can rotate the square rods installed on both sides of the upper ends of the front panel and the back panel to clip them into the inside of the clamping blocks fixedly installed on both sides of the upper ends of the side panels. A fixing column is fixedly installed at one end of the square rod, and the fixing column is clipped to one side of the clamping block, so that it can be effectively and quickly assembled and disassembled.

[0016] Second, after the shield is formed, the worker can rotate the rotating plate to move the movable plate up, so that the formed shield will be loosened, which can ensure that the shield will not be damaged and at the same time quickly improve the production efficiency. Then, the plug-in plate is taken out and the rotating plate is continued to be rotated to make the movable plate continue to move to push the formed shield out better for the workers to take out the shield, and effectively prevent the shield from being damaged due to force when it is taken out. When the movable plate moves, the limit rods are fixedly installed on both sides of the bottom of the movable plate, and the limit rods are slidably installed inside the two sides of the rectangular groove. The limit rods can effectively prevent the movable plate from getting stuck and shaking when it moves, and improve the stability of the movable plate movement. BRIEF DESCRIPTION OF THE DRAWINGS
