Just:
1, it is provided with pedestal and cover board, by the effect of pedestal, cover board, the first snap ring and the second snap ring, is convenient for riser
It is fixedly mounted on the casting top of different sizes, is avoided when actually using riser, not due to different casting dimension sizes
Together, it selects different size of riser to be installed in casting top, increases use cost, then by the effect of frictional layer, just
It in the stability for improving riser installation, avoids when being poured, influences the effect poured, and pass through fixed screw and threaded hole
Effect, convenient for dismantling pedestal, consequently facilitating pedestal of different shapes is selected to be mounted on riser bottom end, expanding it makes
Use range.
2, it is provided with air hole, using the effect of air hole, convenient for carrying out when using riser to the gas in the intracavitary portion of type
Discharge, recycles the effect of collecting tank, convenient for collecting the molten metal that Flowage frontage is mixed with field trash or oxidation film, to reduce casting
On defect, avoid occurring over-cooling structure on casting, and using the effect of heat insulating stuffing, convenient for extending molten metal in riser
The feeding time improves casting finished products quality.
3, it is provided with pinhole, avoids taking increase convenient for improving the intensity of riser by the effect of pinhole and cavity
The mode of Riser Dimensions is heavier while enhancing intensity, and then increase cost, also to easily lead to riser, inconvenient for use, then passes through
The effect of form friction pattern, convenient for increasing the frictional force emitted between discharge surface and hand, consequently facilitating taking and placing.
