Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that the existing gear box mold for locomotive driving device is affected by high-temperature molten metal, which will cause thermal deformation of the mold, so that the structure of the mold cavity will change, resulting in the processed gear box. The yield rate is low, and the service life of the mold is greatly shortened. The present invention provides a gearbox mold for a locomotive driving device. The side molds are respectively equipped with independent cooling ports for cooling the mould, thus effectively solving the problem of thermal deformation of the mold caused by the influence of high-temperature molten metal on the gear box mold for the existing locomotive driving device, making the mold Changes in the cavity structure lead to low yield of the processed gearbox, and greatly shorten the service life of the mold and other issues

Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 and Figure 4 Shown, a kind of gearbox mold for locomotive driving device, comprises formwork shell and mold core, is provided with the first axle hole 1 and the second axle hole 2 on the formwork shell, and formwork shell is made up of front upper side mold 3, rear upper side mold 4. The front lower side mold 5 and the rear lower side mold 6 are composed of the front upper side mold 3, the rear upper side mold 4, the front lower side mold 5 and the rear lower side mold 6 respectively. The front upper side mold 3, The rear upper side mold 4, the front lower side mold 5 and the rear lower side mold 6 are respectively provided with independent cooling ports for cooling the mould. The cooling ports include a cold air port 7 and a cold water port 8. The front lower side mold 5 is respectively provided with a contact surface 10 for connecting the front upper side mold 3 and the front lower side mold 5; the front upper side mold 3 is...

Embodiment 2

[0021] It is basically the same as Embodiment 1, the difference is that: the front upper side mold 3, the rear upper side mold 4, the front lower side mold 5 and the rear lower side mold 6 are respectively provided with cooling fins for increasing the heat dissipation area

[0022] When processing the gearbox, the front upper side mold 3, the rear upper side mold 4, the front lower side mold 5, the rear lower side mold 6 and the mold core are combined to form a gearbox mold, and molten metal is added to the mold through the gate 9 , Install a cold water pipe at the cold water port 8 to cool the mold, and install a cold air pipe at the cold air port 7 to cool the mold. By setting the cold air port 7 and the cold water port 8, the hot joints of the gearbox are cooled to ensure that the box is free of Casting defects improve the yield of the gearbox and greatly increase the service life of the mold.

Abstract

The invention relates to the technical field of gearbox moulds, in particular to a gearbox mold for a locomotive driving device, which includes a mold shell and a mold core. The mold shell consists of a front upper side mold, a rear upper side mold, a front lower side mold and a rear lower mold. The front upper side mold, the rear upper side mold, the front lower side mold and the rear lower side mold are respectively provided with independent cooling ports for cooling the mould, and the cooling ports include cold air ports and cold water mouth. The invention provides a gearbox mold for a locomotive driving device. By setting a cold air port and a cold water port, the thermal deformation of the mold caused by the influence of high-temperature molten metal on the gearbox mold for a locomotive driving device is effectively prevented, and through Set the cold air port and the cold water port to cool the hot section of the gearbox to ensure that there are no casting defects in the case, which improves the yield of the gearbox and greatly increases the service life of the mold, thereby greatly reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of gear box molds, in particular to a gear box mold for a locomotive driving device. Background technique [0002] With the development of my country's economy, rail transit has entered a period of rapid development, which has also brought about a sharp increase in the demand for heavy-duty locomotives, express buses and other rail transit vehicles. Modern rail transit vehicles are developing in the direction of safety, high speed, energy saving, environmental protection, high efficiency, comfort and beauty. At present, the casting of gear boxes for locomotive driving devices mainly adopts low-pressure casting molds. Low-pressure casting molds are a kind of molds used for industrial products to be formed by pressure casting. It is solidified and molded under pressure to be processed into parts. [0003] However, in the actual production process, when the cooling port is improperly set or not set, especiall...
