Description

Technical Field

[0001] The utility model belongs to the technical field of axle box cast steel moulds, and in particular relates to an axle box cast steel mould for internal combustion locomotives. Background Art

[0002] The liquid cooling method of the axle box casting mold for diesel locomotives mainly uses circulating coolant to absorb and take away the heat generated by the mold during the production process to keep the mold temperature stable and improve mold use and product quality. When designing the mold, a cooling channel is pre-set, and the coolant circulates inside the mold, absorbing the heat and flowing to the cooling tower or cooling pool for heat dissipation.

[0003] The cooling channels of traditional technology molds are opened on the mold body. The cooling channels need regular maintenance and cleaning to prevent cooling channel blockage and coolant performance degradation. This requires the entire mold to be disassembled and cleaned, increasing production costs and time costs. In addition, frequent disassembly and installation of the mold may cause damage or deformation of the mold and shorten the service life of the mold. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a die for an axle box steel casting for a diesel locomotive.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold for a cast steel part of an axle box for a diesel locomotive, comprising a mold base and a cooling water ring, wherein a cooling cavity located outside a mold core is provided at the bottom of the mold base; the cooling water ring is inserted into the interior of the cooling cavity from the bottom of the mold base, and a plurality of cooling channels arranged vertically are provided on the cooling water ring, wherein an inner water inlet of the cooling channel is threadedly connected to an outer water inlet, and an inner water outlet of the cooling channel is threadedly connected to an outer water outlet.

[0006] The cooling water ring is used in the cooling cavity at the bottom of the mold to achieve liquid cooling of the mold. The cooling water ring is inserted into the cooling cavity and introduces the coolant into the mold through the cooling channel for cooling. This can effectively absorb and take away the heat generated by the mold during the production process, keep the mold temperature stable, and improve the mold use and product quality.

[0007] Preferably, the cooling water ring is provided with a contoured through hole which is sleeved on the outside of the mold core.

[0008] When the cooling water ring is inserted into the cooling cavity, the contoured through hole can be just covered on the outer side of the mold core, so that the cooling water ring can cool and dissipate heat for the mold core.

[0009] Preferably, a concave groove is formed around the bottom of the mold base, and a protrusion placed inside the concave groove is fixed around the cooling water ring. The cooling water ring is threadedly connected to the mold base via bolts penetrating the protrusion.

[0010] A concave groove is provided around the bottom of the mold base, and the cooling water ring with protrusions can be fixed so that the cooling water ring and the mold base are tightly combined.

[0011] Preferably, the cooling channel is formed by connecting a plurality of inclined cooling channels, and one end of the cooling channel away from the connecting end is blocked by a threaded plug.

[0012] The cooling channel is formed by connecting several cooling channels, which can better guide the flow of coolant.

[0013] Preferably, the cooling channel surrounds the outer periphery of the contoured through hole, which can distribute the coolant more evenly and improve the cooling effect.

[0014] Preferably, the protrusion and the concave groove are provided with mounting holes for threaded connection with matching bolts. The protrusion and the concave groove are provided with mounting holes, which can be threadedly connected with matching bolts to facilitate installation and disassembly of the cooling water ring and the mold base.

[0015] Compared with the prior art, the technical effects and advantages of the utility model are:

[0016] The cooling water ring of the axle box casting mold for diesel locomotives can be easily disassembled independently, which is convenient for regular cleaning and maintenance of the cooling water ring and cooling channel, preventing the cooling channel from being blocked and the performance of the coolant from being degraded. This avoids frequent disassembly and installation of the mold, and extends the service life of the mold. Through the setting of the cooling water ring, the coolant can circulate in the cooling cavity at the bottom of the mold, absorb and take away the heat generated by the mold during the production process, keep the mold temperature stable, and improve the mold use and product quality.

[0017] A concave groove is opened around the bottom of the mold base. By fixing the cooling water ring with a protrusion, the cooling water ring can be closely combined with the mold base, improving the sealing and stability of the cooling system and ensuring the smooth flow of the coolant. This design is conducive to improving the efficiency and service life of the cooling system, and is also convenient for the installation and removal of the cooling water ring;

[0018] The setting of multi-layer cooling channels can effectively improve the cooling effect. This design can make the coolant more evenly distributed and improve the cooling effect. The cooling channel is connected by several inclined cooling channels, each cooling channel is connected to the adjacent cooling channel, and the end away from the connection is blocked by a threaded plug. This design can better guide the flow of coolant, avoid coolant leakage, and facilitate cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
