Description

Technical Field

[0001] This utility model relates to the field of track slab steel mold technology, specifically to an assembly-type track slab steel mold that is easy to demold. Background Technology

[0002] Track slabs are the foundation components of railway tracks. As an important tool for producing track slabs, prefabricated track slab steel molds are used in the construction of high-speed railways, which has increased the demand for and quality of high-speed railway track slabs. Track slabs are usually cast in track slab steel molds. As the demand for track slabs increases, the requirements for track slab steel molds are also becoming higher.

[0003] Existing prefabricated track slab steel molds are complex and labor-intensive to demold, making it difficult to efficiently remove the formed track slabs from the mold. This not only affects production efficiency but may also damage the track slabs due to improper handling during demolding, affecting their quality. Furthermore, existing steel mold structures lack flexibility in meeting the production needs of track slabs of different specifications, making it difficult to quickly and easily disassemble and replace key components to adjust the mold assembly. This necessitates preparing multiple sets of steel molds for producing different specifications of track slabs, increasing production costs. Therefore, those skilled in the art have provided a prefabricated track slab steel mold that facilitates demolding, thereby solving the problems mentioned in the background art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an assembly-type track slab steel mold that facilitates demolding. This solves the problem that existing assembly-type track slab steel molds are difficult to efficiently remove the formed track slab from the mold during demolding operations. At the same time, the existing steel mold structure lacks flexibility, making it difficult to quickly and easily disassemble and replace key components to adjust the mold assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated track slab steel mold that is easy to demold, comprising a bottom mold, a first side plate, and a second side plate, wherein the first side plate and the second side plate are rotatably hinged to the side of the bottom mold, characterized in that: a lifting plate is inserted into the bottom mold, an arc-shaped plate is installed at the end where the first side plate intersects with the bottom mold, an assembly groove is provided on the bottom mold, a circular groove is provided on the inner side of the bottom end of the assembly groove, an assembly module is slidably inserted into the assembly groove, and a cross-shaped locking block is rotatably engaged on the bottom side of the assembly module.

[0006] Preferably, the bottom mold has a mounting groove, a positioning bolt is vertically installed in the mounting groove, a spring is sleeved around the periphery of the positioning bolt, the bottom of the lifting plate has a positioning groove, the lifting plate is slidably inserted into the mounting groove, the positioning groove is slidably engaged with the positioning bolt, one end of the spring is in abutting contact with the top protruding ring of the positioning bolt, and the other end of the spring is in abutting contact with the bottom inner wall of the positioning groove. Under the action of the spring, the lifting plate can be at the same level as the upper surface of the bottom mold when it is not lifted.

[0007] Preferably, the two ends of the placement groove are provided with arc-shaped grooves, the arc-shaped plate is rotatably inserted into the arc-shaped groove, and the end of the arc-shaped plate is in abutting contact with the lifting plate, thereby lifting the track plate formed on the bottom mold, thus facilitating the demolding of the track plate.

[0008] Preferably, the assembly module has a limiting groove on its bottom side, and the cross-shaped locking block is fitted with a limiting bolt facing the upper side of the assembly module. The cross-shaped locking block is rotatably engaged with the limiting groove through the limiting bolt. After rotation, the cross-shaped locking block engages with the circular groove. Before the assembly module enters the assembly groove, the cross-shaped locking block is in an X shape. After the assembly module enters the assembly groove, the cross-shaped locking block is rotated so that it rotates to a cross shape and engages with the circular groove, thereby quickly fixing the assembly module.

[0009] Preferably, a first positioning hole is provided on the first side plate, and a second positioning hole is provided on the second side plate. The corners of the first and second side plates are in meshing contact. A U-shaped limiting rod is inserted into the first positioning hole. The U-shaped limiting rod is inserted into the first and second positioning holes at opposite corners of the first and second side plates. As the U-shaped limiting rod is inserted into the first and second positioning holes at opposite corners of the first and second side plates, the first and second side plates surrounding the bottom mold are stably fixed. The surface of the U-shaped limiting rod is provided with anti-slip texture. The anti-slip texture adopts a regularly arranged concave-convex stripe design. When the operator inserts or removes the U-shaped limiting rod, the anti-slip texture can increase the friction between the hand and the U-shaped limiting rod, making the operation more effortless and convenient, avoiding the situation where it is difficult to insert or remove due to slipping or the U-shaped limiting rod accidentally falling off, thus improving the stability and safety of the operation.

[0010] Preferably, the top surface of the lifting plate and the surface of the bottom mold are provided with an anti-stick coating. The anti-stick coating is made of nano-sized ceramic particles and high molecular polymer composite. While ensuring the structural strength of the lifting plate, it can effectively reduce the adhesion force between the track plate and the surfaces of the lifting plate and the bottom mold during molding, making it easier for the track plate to separate from the lifting plate and the bottom mold during demolding, further improving the convenience of demolding. In addition, the anti-stick coating has good wear resistance and corrosion resistance, which can extend the service life of the lifting plate and the bottom mold.

[0011] Compared with the prior art, this utility model provides an assembly-type track slab steel mold that is easy to demold, and has the following beneficial effects: Through design, in this prefabricated track slab steel mold, the first side plate and the second side plate are rotatably hinged to the bottom mold, and a lifting plate is inserted into the bottom mold. When the first side plate expands and rotates outward, the arc-shaped plate presses against the lifting plate, causing it to protrude from the horizontal plane of the bottom mold, thereby lifting the track slab formed on the bottom mold, which greatly facilitates the demolding operation of the track slab. In addition, the bottom mold has assembly slots and circular slots. The assembly modules are set in various types and have cross-shaped locking blocks at the bottom. By changing the shape of the cross-shaped locking blocks before and after entering the assembly slot and cooperating with the circular slot, the assembly modules can be quickly fixed. At the same time, this structure allows the assembly modules to be quickly disassembled and replaced. By changing the assembly modules according to different needs, the steel mold combination can be changed, thereby meeting the requirements for casting track slabs of different specifications and reducing production costs.

Under the action of the spring 7, the lifting plate 5 can be at the same level as the upper surface of the bottom mold 1 when it is not lifted. Arc grooves 102 are provided at both ends of the placement groove 101, the arc plate 4 is rotatably inserted into the arc groove 102, and the arc plate 4 is pressed against the end of the lifting plate 5, thereby lifting the track plate formed on the bottom mold 1, thus facilitating the demolding of the track plate; A limiting groove 801 is provided on the bottom side of the assembly module 8, and a limiting bolt 901 is installed on the upper side of the cross-shaped locking block 9 facing the assembly module 8. The cross-shaped locking block 9 is rotated and engaged with the limiting groove 801 through the limiting bolt 901. After the cross-shaped locking block 9 rotates, it engages with the circular groove 104. Before the assembly module 8 enters the assembly groove 103, the cross-shaped locking block 9 is in an X shape. After the assembly module 8 enters the assembly groove 103, the cross-shaped locking block 9 is rotated so that the cross-shaped locking block 9 rotates to a cross shape and engages with the circular groove 104, thereby quickly fixing the assembly module 8. A first positioning hole 201 is provided on the first side plate 2, and a second positioning hole 301 is provided on the second side plate 3. The corners of the first side plate 2 and the second side plate 3 are in meshing contact. A U-shaped limiting rod 10 is inserted into the first positioning hole 201. The U-shaped limiting rod 10 is inserted into the first positioning hole 201 and the second positioning hole 301 at the opposite corners of the first side plate 2 and the second side plate 3.

Moreover, the anti-stick coating has good wear resistance and corrosion resistance, which can extend the service life of the lifting plate 5 and the bottom mold 1.

[0021] The working principle of this device is as follows: The prefabricated track plate steel mold consists of a bottom mold 1, a first side plate 2, and a second side plate 3.

The arc-shaped plate 4 is rotatably inserted into the arc-shaped groove 102. When the first side plate 2 expands and rotates outward, the arc-shaped plate 4 can press against the end of the lifting plate 5. As the first side plate 2 becomes flush with the bottom mold 1, the lifting plate 5 is pressed against the horizontal surface of the bottom mold 1 by the arc-shaped plate 4, thereby lifting the track plate formed on the bottom mold 1, thus facilitating the demolding of the track plate.

In this structure, the assembly module 8 can be quickly disassembled and replaced. Furthermore, the prefabricated track plate steel mold can be combined and changed by the replaceable assembly module 8 to cast track plates with different requirements. Furthermore, during the casting of the track slab, the first side plate 2 and the second side plate 3 are rotated to an upright position. Then, the first positioning hole 201 and the second positioning hole 301 at opposite corners of the first side plate 2 and the second side plate 3 can be inserted through the U-shaped limiting rod 10, thereby stably fixing the first side plate 2 and the second side plate 3 surrounding the bottom mold 1.
