Description

Cooling device for hub casting

Technical Field

The utility model relates to a wheel hub casts the field, especially relates to a cooling device is used in wheel hub casting.

Background

In recent years, the automobile industry is rapidly developed, and most of automobile hubs are produced by adopting aluminum alloy materials. According to the current market demand and cost control, low-pressure casting is mainly used. The low pressure casting mould is in including the upper and lower module of upper and lower arranging and arranging side module between the upper and lower module, upper and lower module with the side module encloses into the die cavity that is used for casting wheel hub, the die cavity is including the rim die cavity that is used for casting the rim and the spoke die cavity that is used for casting the spoke. The spoke cavities are filled with the rim cavities from bottom to top. The temperature of the cast casting is very high, and in order to ensure the sequential solidification of the casting and improve the casting efficiency, a heat dissipation device for the casting is often arranged on the mold. However, the heat dissipation efficiency of the part of the hub, which extends into the die, is low, so that the heat dissipation of the whole hub is not uniform, and the quality problems of slag holes and the like of a final product are caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cooling device is used in wheel hub casting that cools off high efficiency, and can improve and go deep into the low problem of mould part radiating efficiency.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a cooling device is used in wheel hub casting, includes the side form between last mould, lower mould and the upper and lower mould, and upper and lower mould and side form enclose into the die cavity that is used for casting wheel hub, still is equipped with and buries underground in this internal spiral cooling pipe of last mould, spiral cooling pipe is spiral disk pipeline, including water inlet, delivery port and cooling pipe fitting, water inlet and the inside helicitic texture that all is equipped with of delivery port, the lower mould corresponds wheel hub's spoke position and is equipped with the cooling rod, the side form is equipped with the cooling ring pipeline in upper and lower R angle department.

Preferably, the water inlet of the spiral cooling pipeline is arranged at the upper end of the pipeline, and the water outlet is arranged at the lower end of the pipeline.

Preferably, the heat dissipation rod is a red copper rod, and a plurality of heat dissipation holes are formed in the lower end portion of the heat dissipation rod exposed out of the lower die.

Preferably, the cooling annular pipelines are symmetrically distributed in the two side molds and are tightly attached to the inner wall of the R corner of the side mold.

Compared with the prior art, the beneficial effects of the utility model are that: through setting up cooling ring pipeline, heat dissipation stick and spiral cooling pipeline, to the part that wheel hub gos deep into the mould with be difficult to radiating part, promote the radiating efficiency, make the holistic heat dissipation of wheel hub even, avoid appearing a large amount of dregs holes, improved the quality of product.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a cooling device is used in hub casting, includes mould 1, lower mould 2 and the side form 3 between the upper and lower mould, and upper and lower mould and side form 3 enclose into the die cavity that is used for casting wheel hub, still is equipped with to bury underground in the internal spiral cooling tube 4 of mould 1, spiral cooling tube 4 is spiral disc pipeline, including water inlet 41, delivery port 42 and cooling pipe fitting 43, water inlet 41 and delivery port 42 inside all are equipped with helicitic texture, lower mould 2 corresponds wheel hub's spoke position and is equipped with radiating rod 21, side form 3 is equipped with cooling ring pipeline 31 in upper and lower R angle department.

Referring to fig. 1, during the casting, the cooling water gets into from the water inlet 41 of spiral cooling pipe 4, from last to down through cooling pipe 43, flow out from delivery port 42, cool off the foundry goods, the part that the radiating rod 21 that lower mould 2 corresponds the spoke position setting of wheel hub deepens the spoke absorbs the heat simultaneously, give off the heat from a plurality of louvres, the water inlet 311 of the cooling ring pipeline 31 that the R angle department set up about both sides side form 3 begins to intake, rivers flow out by delivery port 312 through the pipeline and cool off wheel hub R angle department, thereby it is low to solve wheel hub and deepen the partial radiating efficiency of mould, influence the problem of finished product quality.

To sum up, the utility model discloses a set up the cooling ring pipeline, heat dissipation stick and spiral cooling pipeline deepen the part of mould to wheel hub, promote the radiating efficiency, make the holistic heat dissipation of wheel hub even, avoid appearing a large amount of cinder holes, improved the quality of product.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
