[0002] At present, domestic automobile tire aluminum alloy mold precision casting generally adopts casting processes such as gravity casting, low-pressure casting or gravity low-pressure casting. The soup channel (also called the runner) in casting is a very critical casting tooling step, and the gypsum-type soup channel is generally used. A gypsum-shaped soup can only be used once, and because the gypsum-shaped soup needs to be made, dried and assembled,

Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0014] Such as figure 1 , the present invention comprises soup channel 1, soup channel bottom plate 2, metal mold 3, gypsum type 4, casting mold 5, runner opening 6, reinforcing rib 7, dividing rib 8, heat preservation zone 9 and heat dissipation zone 10, wherein metal mold 3 is positioned at In the outermost layer, the metal mold 3 is provided with a casting mold 5 and a plaster mold 4, a runner opening 6 is arranged in the middle of the soup channel base plate 2, and a circle of dividing ribs 8 is arranged on the soup channel base plate 2, and the dividing ribs 8 connect the back side of the soup channel 1 Divided into heat preservation area 9 and heat dissipation area 10, the heat preservation area 9 on the back of the soup channel corresponds to the inner cavity of the soup channel front, the heat preservation area 9 is located on the inner side of the dividing r...

The invention provides a tire mold casting device which comprises a runner, a runner bottom plate positioned at the bottom of the runner, and a metal mold positioned on the uppermost part of the runner, wherein a gypsum mould is arranged in the metal mold; a casting mould is arranged between the metal mold and the gypsum mould; the inner cavity of the front side of the runner comprises four pouring gates; the four pouring gates are communicated with a runner opening in the bottom of the runner; and reinforcing ribs are arranged around the runner opening in the rear surface of the runner. With the adoption of the design of the four pouring gates, flow of a casting liquid is promoted, the volume of the residual molten aluminum is small, a thermal insulation area is formed in the inner cavity of the runner and is coated with a thermal insulation material, a heat dissipation area is reserved outside the inner cavity of the runner and is distinguished from the thermal insulation area, the heat dissipation space is fast in heat dissipation, and cooling molding of the casting liquid is promoted. Four reinforcing ribs are arranged on the pouring gates of the runner, the device is difficult to degenerate in the using process for a long time, the assembling and sealing stability of a liquid riser tube is improved, and the casting quality is guaranteed.
Description
technical field [0001] The invention relates to a casting device, in particular to a tire mold casting device. Background technique [0002] At present, domestic automobile tire aluminum alloy mold precision casting generally adopts casting processes such as gravity casting, low-pressure casting or gravity low-pressure casting. The soup channel (also called the runner) in casting is a very critical casting tooling step, and the gypsum-type soup channel is generally used. A gypsum-shaped soup can only be used once, and because the gypsum-shaped soup needs to be made, dried and assembled, a plaster-shaped soup needs to be made for each casting, which is time-consuming and laborious, and the production cost of the gypsum-shaped soup is relatively high , so the manufacturing cost of the tire mold is high. At the same time, due to the poor heat dissipation of the gypsum, the surface roughness of the casting is large, and defects such as shrinkage and porosity are prone to occur, ...
