Embodiment 1

[0019] A casting mold for a hub, comprising a mold base 4, on which a fixed mold and a movable mold are fixed, and a cavity 7 for forming a hub is formed between the fixed mold and the movable mold, and the mold base 4 is in the shape of a basket , the fixed mold includes a cylindrical side mold 2, and the movable mold includes a top mold 1 and a bottom mold 3, and the top mold 1 and the bottom mold 3 extend into the side mold 2 from different ends of the side mold 2 respectively. In the hollow area, the top mold 1 or bottom mold 3 is also provided with a sprue 6 located in the center of the cavity 7, and the top mold 1, bottom mold 3 and side mold 2 are also provided with a medium flow for cooling medium circulation. Road 5.

[0020] In this embodiment, the movable mold is used to divide the top mold and the bottom mold 3, and the different ends of the side mold 2 are respectively loaded into the hollow area of ​​the side mold 2 to jointly form the structural characteristics ...

Embodiment 2

[0022] The present embodiment is further limited on the basis of Embodiment 1: in order to improve the controllability of the temperature drop of the thermal hub, the design of the preferred top mold 1 and the bottom mold 3 mainly considers the respective strengths, so the top mold 1 and the bottom mold 3 can be combined The mold 3 is set relatively thin, and preferably, the thicknesses of the top mold 1 and the bottom mold 3 are both between 25-30mm.

[0023] In order to facilitate concentrated cooling of the ribs formed, the medium flow channel 5 on the top mold 1 and the bottom mold 3 is along the length direction of the hub rib cavity in the cavity 7 .

[0024] In order to control the cooling rate at each point of the hub, there are more than one medium flow channels 5 on the top mold 1 , bottom mold 3 and side mold 2 , and each medium flow channel 5 is provided with an independent inlet.

[0025] In order to reduce air holes in the hub as much as possible, the pouring por...

Abstract

The invention discloses a wheel hub casting mold which comprises a mold base, wherein a fixed mold and a movable mold are fixed on the mold base; a cavity for forming a wheel hub is formed between the fixed mold and the movable mold; the mold base is in a basket shape; the fixed mold comprises a barrel-shaped side mold; the movable mold comprises a top mold and a bottom mold; the top mold and the bottom mold extend into a hollow area of the side mold from the different ends of the side mold; a sprue gate located in the middle of the cavity is further formed in the top mold or the bottom mold; and medium flow passages for allowing a cooling medium to circulate are further arranged on the top mold, the bottom mold and the side mold. The mold is convenient to remove, can shorten a casting cycle of the wheel hub and further facilitates the improvement on mechanical properties of the wheel hub at the same time.

Description

technical field [0001] The invention relates to the field of automobile wheel hub manufacturing equipment, in particular to a wheel hub casting mold. Background technique [0002] The wheel hub of automobile in the prior art can be divided into steel wheel hub and alloy wheel hub two big classes according to material. The main advantage of steel wheels is that the manufacturing process is simple, the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and strong. However, the disadvantages of steel wheels are also relatively prominent, which are ugly appearance (it can be said that there is no appearance at all), heavy weight (same wheel steel material is much heavier than aluminum alloy material), large inertial resistance, and poor heat dissipation. And it is very easy to rust Relatively speaking, the alloy wheel hub can just make up for this problem, light weight, small inertial resistance, high manufacturi...
