Description

Technical Field

[0001] This application relates to the field of railway sleeper mold technology, and in particular to a double-block railway sleeper mold. Background Technology

[0002] With the development of railways, various new types of ballastless tracks, which replace ballast track beds with concrete or asphalt mixtures, aim to improve track stability and smoothness, and significantly reduce maintenance workload. Ballastless tracks have been widely laid and applied on newly built high-speed railway trunk lines, achieving excellent technical and economic results.

[0003] In related technologies, a corresponding double-block sleeper mold is designed and integrally cast for the double-block sleeper to be used, and the double-block sleeper is manufactured using the double-block sleeper mold.

[0004] However, the mold for casting two-block sleepers in one piece, which is required for the use of two-block sleepers, is difficult to use to meet the production needs of multiple types of two-block sleepers. Summary of the Invention

[0005] This application provides a double-block sleeper mold, which at least overcomes the problem in the related art that double-block sleeper molds are difficult to use to meet the production needs of multiple types of double-block sleepers.

[0006] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0007] This application provides a double-block sleeper mold, comprising: an outer shell and multiple double-block sleeper shells; the outer shell has multiple cavities; the double-block sleeper shell includes a metal outer shell and a release layer, the surface roughness of the metal outer shell is less than a roughness threshold, and the release layer is formed by spraying a release agent onto the inner side of the metal outer shell; each cavity is provided with at least one hole, and a fixing structure is provided around each hole, the fixing structure being located on the outside of the cavity; the outer side of the metal outer shell is provided with multiple protruding structures that cooperate with the at least one hole, and the protruding structures are detachably connected to the fixing structure through the corresponding holes.

[0008] By configuring a cavity separately in the outer shell and configuring a double-block sleeper shell that can be detachably fitted with the cavity, the same double-block sleeper mold can be adapted to the production needs of different types of double-block sleepers by changing the double-block sleeper shell.

[0009] Furthermore, by configuring a release layer in the double-block sleeper shell, it is beneficial to demold the double-block sleeper after casting. In addition, configuring the surface roughness of the metal shell to be less than the roughness threshold is beneficial to the adhesion of the release layer and to maintaining the flatness of the release layer, which in turn is more conducive to demolding.

[0010] In one embodiment of this application, each cavity is further provided with a plurality of limiting holes, and the outer side of the metal shell is further provided with a plurality of limiting posts that cooperate with the plurality of limiting holes.

[0011] By setting multiple limiting holes in the cavity and setting limiting posts on the outside of the metal shell that cooperate with the limiting holes, it is beneficial to replace and align the double-piece sleeper shell, thereby ensuring production quality and the convenience of replacing the double-piece sleeper shell.

[0012] In one embodiment of this application, each cavity is symmetrically provided with at least a pair of first pushing holes, and each double-block sleeper shell is provided with at least a pair of second pushing holes that cooperate with the at least a pair of first pushing holes; the double-block sleeper mold further includes a pushing device, the pushing device having multiple sets of pushing arms, each set of pushing arms corresponding to a double-block sleeper shell, and each set of pushing arms including at least a pair of pushing arms that cooperate with the at least a pair of first pushing holes.

[0013] The addition of a jacking device facilitates demolding of the twin-block sleepers after casting.

[0014] In one embodiment of this application, the double-block sleeper mold further includes a vibration demolding mechanism disposed on the side of the outer shell, for driving the outer shell to vibrate at a preset frequency.

[0015] Configuring a vibration demolding mechanism helps in demolding the twin-block sleepers after casting.

[0016] In one embodiment of this application, the plurality of double-block sleeper shells are of the same model or the plurality of double-block sleeper shells include at least two models of double-block sleeper shells. Attached Figure Description
