Problems solved by technology

[0007] The purpose of the present invention is to overcome the existing track slab molds in the prior art that each track slab needs to be clamped and removed separately before and after production, so that the accuracy and flatness of each track slab produced by it are consistent. It is difficult to guarantee the above-mentioned deficiencies in terms of performance requirements, and provide a method for producing a track plate that can be reused, fixed and not disassembled, and a method for separating the track plate from the mold

Embodiment

[0068] Such as Figure 1-3 As shown, the track plate mold of the present invention includes an end mold 1, a side mold 2, a bottom mold 3 and a jacking area 4, and the mold cavity surrounded by the end mold 1, the side mold 2 and the bottom mold 3 is used for making Ballastless track slabs;

[0069] In addition, it also includes a sealing structure 5 at the junction between molds on one side of the mold cavity, and a plurality of bearing rail groove cavities 6 that are symmetrically distributed on both sides of the cavity on one side of the bottom mold 3 .

[0070] The inclination angle θ between the inner wall of the end mold 1 and the upper surface of the bottom mold 3 is 90°<θ<180°, and the inclination angle γ between the inner wall of the side mold 2 and the upper surface of the bottom mold 3 is 90°<γ<180°. Compared with the method in which the inner wall of end mold 1 and the inner wall of side mold 2 of the traditional ballastless track slab mold are respectively perpen...

Abstract

The invention discloses a ballastless track board mould and a track board demoulding method. According to the invention, a mould cavity formed by the inner wall of an end mould, the inner wall of a side mould and the upper surface of a bottom mould in a surrounding manner is used for producing ballastless track boards; the inner wall of the end mould and the upper surface of the bottom mould form an inclination angle theta, and theta is greater than 90 degrees and less than 180 degrees; the inner wall of the side mould and the upper surface of the bottom mould form an inclination angle gamma, and gamma is greater than 90 degrees and less than 180 degrees; the projection of the bottom of the cavity on the upper opening plane of the cavity is located in an area of the upper opening plane of the cavity; and jacking demoulding structures convenient for jacking each track board from the mould cavity from bottom to top to demould is arranged on the bottom mould. By applying the ballastless track board mould and the track board demoulding method, which are disclosed by the invention, mould assembly and mould disassembly have no need to be carried out again during each track board production, and the installed and adjusted mould is repeatedly used, thus the high requirements of consistency indexes of accuracy, smoothness and the like on the track boards produced by the mould are ensured while the working efficiency is increased; and moreover, the requirements and the workload of mould installation and adjustment personnel are reduced, thus efficient production is ensured, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a mold for a ballastless track slab and a demoulding method for the track slab. Background technique [0002] With the rise of high-speed railways, in order to ensure the high-speed operation of trains on the rails, ballastless track slabs have appeared to replace traditional railway sleeper systems. According to the structure of existing ballastless track slabs and the extremely high precision and Flatness requirements, the existing ballastless track slabs in the production process, the use of preset molds, prefabrication of the mold before the track slab molds, prefabricated and then demoulding method. which is, [0003] When using molds to make ballastless track slabs, it is necessary to close each mold to form the cavity shape of ballastless track slabs, and then adjust the molds precisely to meet the shape, size, surface parameters, internal reinforcement layout...
