Gap size between water pipe is less than 0.5mm.
As an improvement of the above scheme, the axial direction along transition screw is seen, it is long that the length of multi-diameter shaft is greater than transition screw
The half of degree, the multi-diameter shaft extend from the nut of transition screw.
As an improvement of the above scheme, the axial direction along transition screw is seen, the length of multi-diameter shaft is long between transition screw
The half and a quarter of degree, the multi-diameter shaft are located among the shaft of transition screw.
As an improvement of the above scheme, the axial direction along transition screw is seen, the length of the second stepped hole is greater than transition spiral shell
The half of length is followed closely, which extends from the head of transition screw.
As an improvement of the above scheme, the axial direction along transition screw is seen, the length of the second stepped hole is between transition spiral shell
The half and a quarter of length are followed closely, the second ladder hole location is among the shaft of transition screw.
The utility model has the beneficial effects that gap structure can make to form closed sky between mold and point fortune hydrophone around here
Chamber finds that the maximal clearance of transition screw and mold is less than 0.5mm and mistake after the liquid tension of reasonable analysis molten aluminum
The minimum clearance for crossing screw and point fortune water pipe is less than 0.5mm, and when cold head is broken, molten aluminum is difficult to overflow, such anti-race aluminium.This
Outside, this gap can rationally design tolerance fit when processing, then self-assembling formation, for the angle of processing,
It is extremely convenient.
