Description
Technical field
The utility model belongs to lost foam casting process technical field, is specifically related to a kind of casting mechanism for wheel hub lost foam casting process.
Background technology
Current new casting technique with fastest developing speed when lost foam casting, and coating technology is successfully one of key of this technique, at present most lost foam casting manufacturer of China adopts self-control coating to deal with production, and the cast(ing) surface that obtains is coarse, even produce casting flaw.
Existing wheel hub generally adopts sand casting, also needs to make fuse, complex process when moulding, wall thickness is difficult for ensureing, percent defective is high, and production efficiency is low, also has at present the evaporative pattern of employing cast valve body, need not play core, only need to use foamed polystyrene bead, through foaming, make evaporative pattern model, through combination bonding, surface brush fireproof coating, oven dry, bury case with dry sand, under negative pressure, pours into a mould, evaporative pattern gasification disappears, form foundry goods, but white mould intensity is low, then through brushing, dry, bury the operations such as case, easily cause distortion, percent defective is high.
Utility model content
Utility model object: the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of casting mechanism for wheel hub lost foam casting process.
Technical scheme: the utility model discloses a kind of casting mechanism for wheel hub lost foam casting process, comprise front casting mechanism and rear casting mechanism, described front casting mechanism and rear casting mechanism include on horizontal running channel and the horizontal running channel of connection and the connection gate of the white mould upper edge hole that disappears, this connection gate is frustum cone structure wide at the top and narrow at the bottom, the center of the horizontal running channel of described front casting mechanism and rear casting mechanism is equipped with oblique running channel, the upper port of the oblique running channel of front casting mechanism is all connected with vertical running channel with the upper port of the oblique running channel of rear casting mechanism, the utility model is by casting mechanism before and after adopting, solve the undesirable problem of cast effect that upper and lower casting mechanism exists, in the prerequisite that ensures cast efficiency, improve casting quality, so raising casting quality.
As further optimization of the present utility model, connection gate described in the utility model is arranged in pairs in disappearance Bai Mo upper edge, because the upper edge of wheel hub evaporative pattern is circular, therefore connection gate is arranged in pairs on its diameter line, ensure cast effect, improve cast efficiency simultaneously.
As further optimization of the present utility model, the upper internal diameter of connection gate described in the utility model is 1.3-1.5 times of its lower internal diameter, the lower internal diameter and the horizontal running channel internal diameter that connect gate are consistent, connect gate and adopt large upper internal diameter to ensure the continuity in casting process, adopt the lower internal diameter consistent with horizontal running channel internal diameter to ensure uniformity and the stability of cast.
As further optimization of the present utility model, vertical running channel described in the utility model upper end is provided with cup.
As further optimization of the present utility model, the angle of oblique running channel described in the utility model and horizontal running channel is 10-15 °, ensures that oblique running channel is connected gently with horizontal running channel, and then ensures that casting process is even gently.
As further optimization of the present utility model, horizontal running channel described in the utility model is consistent with the inner and outer diameter of oblique running channel, ensures that oblique running channel is connected gently with horizontal running channel, and then ensures that casting process is even gently.
As further optimization of the present utility model, the internal diameter of vertical running channel described in the utility model is 2-2.2 times of oblique running channel internal diameter, ensures in casting process, and cast on average enters in forward and backward casting mechanism, improves cast reliability.
Beneficial effect: the utility model compared with prior art, has the following advantages: adopt the evaporative pattern technique of casting mechanism of the present utility model, the white mould cast effect that disappears is good, and then the big hub structural strength of casting is high, not yielding, yield rate is high, has good economic benefit.
