Abstract

The utility model discloses a cold ring, which comprises a ring-shaped cold ring body (1), wherein the cold ring body (1) is divided into two equal parts, namely, two semi-ring bodies (1.1) along the center line; the two semi-ring bodies (1.1) are mounted on two corresponding lateral molds (2) respectively; the inside walls of the two semi-ring bodies (1.1) take the shapes matched with those of rear wheel rims of wheel hubs (3) ; cooling water channels (1.1.1) extending to two end parts thereof are arranged in the two semi-ring bodies (1.1); the cooling water channels (1.1.1) are communicated with the respective water inlet pipes (4) and water outlet pipes (5). The cold ring provided by the utility model has the advantages of accelerating the cooling speed of the rear wheel rims of the wheel hubs, increasing the density of aluminum alloy solution crystallization, and further improving the mechanical properties of the rear wheel rims of the wheel hubs.

Description

Cold ring

Technical field:

The utility model relates to a kind of cooling device that is used on the aluminium alloy automobile hub gravitational casting mould, especially a kind of being installed on the side form at the cold ring that cools off the wheel hub rear rim.

Background technology:

At present, because on the aluminium alloy automobile hub gravitational casting mould cooling device not being set generally cools off the wheel hub rear rim, cause the cooling velocity of wheel hub rear rim slow, the density of aluminium liquid crystallization is not high, has reduced the mechanical property of wheel hub rear rim to a certain extent.

The utility model content:

The technical problems to be solved in the utility model is: a kind of cooling velocity of accelerating the wheel hub rear rim is provided, the density of aluminium alloy solution crystallization is increased, and then improve the cold ring of the mechanical property of wheel hub rear rim.

For solving the problems of the technologies described above, the utility model adopts a kind of so cold ring: it comprises cold ring body in the form of a ring, and this cold ring body is divided into two along center line, is divided into two hemizonids; Described two hemizonids are installed on two corresponding side forms separately; The madial wall of described two hemizonids is the shape that matches with the wheel hub rear rim; Be provided with in described two hemizonids and extend to the cooling-water duct of end, two ends separately; Described cooling-water duct is communicated with separately water inlet pipe and outlet pipe.

After adopting above structure, the utility model compared with prior art, have the following advantages: owing to be provided with the cold ring of above structure, cooling water flows to from the water inlet pipe of cold ring halfbody one end, in the process of cooling-water duct of flowing through the wheel hub rear rim is cooled off, final cooling water flows out from the outlet pipe of the cold ring halfbody other end again.Adopt the cold ring of above structure to accelerate the cooling velocity of wheel hub rear rim, the density of aluminium liquid crystallization is increased, and then improved the mechanical property of wheel hub rear rim.

As improvement, described cooling-water duct is communicated with separately water inlet pipe and outlet pipe, and cooling water is fully flowed through to the other end from an end of cooling-water duct, has fully cooled off the wheel hub rear rim.

The specific embodiment:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figures 1 to 4, cold ring of the present utility model, it comprises cold ring body 1 in the form of a ring, this cold ring body 1 is divided into two along center line, is divided into two hemizonids 1.1; Described two hemizonids 1.1 are installed on two corresponding side forms 2 separately; The madial wall of described two hemizonids 1.1 is the shape that matches with wheel hub rear rim 3, and promptly the madial wall of two hemizonids 1.1 is close to the lateral wall of wheel hub rear rim 3, and has the shape that the lateral wall with wheel hub rear rim 3 matches; Be provided with in described two hemizonids 1.1 and extend to the cooling-water duct 1.1.1 of end, two ends separately; Described cooling-water duct 1.1.1 is communicated with separately water inlet pipe 4 and outlet pipe 5.

For cooling water is fully flowed through to the other end from the end of cooling-water duct 1.1.1, fully cool off wheel hub rear rim 3, water inlet pipe 4 and outlet pipe 5 are arranged on the two ends of cooling-water duct 1.1.1 separately.

Below only just the preferred plan of the utility model embodiment is described, but can not be interpreted as it is restriction claim.The utility model not only is confined to above embodiment, and its concrete structure allows multiple variation, as long as the variation in these claims is all within protection domain of the present utility model.
