Detailed Description

Referring to fig. 1-2, a high strength flywheel shell manufacture equipment includes from last mould 7, lower mould 4 and well mould 5 that sets gradually down, go up mould 7, lower mould 4 and well mould 5 and enclose into pouring cavity 9, lower mould 4 open have with the first pouring tube 3 of pouring cavity 9 intercommunication, go up mould 7 open have with the second pouring tube 8 of pouring cavity 9 intercommunication, through first pouring tube 3 and second pouring tube 8 to let in the pouring cavity 9 pouring liquid, well mould 5 can be gone up mould 7 relatively and open in order with will flywheel shell in the pouring cavity 9 takes out. The second pouring tube 8 is connected to a conveying device (not shown) for conveying the pouring liquid into the pouring chamber 9, which conveying device can be realized by conventional techniques.

The casting device is characterized by further comprising a box body 1 arranged at the lower end of the lower die 4, wherein the first casting pipe 3 penetrates through the box body 1, and a pressurizing air pipe 2 communicated with an inner cavity of the box body 1 is further arranged on one side of the box body 1; the pressurized air pipe 2 is positioned above the pouring liquid in the inner cavity of the box body 1; the box body 1 is also provided with a pressure sensor (not shown in the figure) for monitoring the pressure of the inner cavity of the box body; the box body 1 is also provided with a heating device for heating the pouring liquid in the inner cavity thereof), which is not shown in the figure.
