Abstract
The invention discloses an improved aluminum wheel cast mould, which comprises a top mould 1, a through hole is arranged at the connection position of spokes and a rim of a wheel blank (3) on the front face of the top mould (1) and inserted into a hollow pipe (2). The hollow pipe (2) is close to the top mould in material. A processing method of the improved aluminum wheel casting mould is further disclosed.
Description
Technical field
The present invention relates to the cast aluminum alloy wheel mould.
Background technology
In the cast aluminum alloy wheel product defects, shrinkage porosite is the difficult problem that casting process needs to be resolved hurrily always.Shrinkage porosite can be divided into according to the difference that shows the wheel blanks position: rising head shrinkage porosite, spoke shrinkage porosite, spoke and wheel rim junction shrinkage porosite, wheel well position shrinkage porosite, wheel rim middle part shrinkage porosite etc.And spoke and wheel rim junction shrinkage porosite are commonly called as R angle shrinkage porosite.The common method of handling at present R angle shrinkage porosite is to bore cooling holes in the position, back of the body chamber of corresponding backform, but this method is limited by backform back of the body cavity space, makes the cooling holes of drill bit processing not reach desired angle, and the hole after the processing is in low level, is prone to fall into various impurity and stops up.The method that other has is that the real core iron rod of adding water-cooled is air-cooled with the real core copper rod of adding; The former intensity of cooling is too big; Moment, difference variation was fast; Hot contraction ratio is too big between latter's material, so that the two all makes backform body and mold insert welding position easy to crack, causes the mold repair cost to increase and die life shortens.
Summary of the invention
The invention provides a kind ofly, make it be difficult for accumulated slag, the wind pawl is put into more easily, effectively reduces the aluminum vehicle wheel casting mould of spoke and wheel rim junction shrinkage porosite class defective the backform local modification.
The present invention solves the technical scheme that its technical problem takes: wheel blanks spoke and wheel rim junction are provided with through hole in the backform front, are bumped into hollow pipe, and said hollow pipe is close with the backform material.
The processing method of casting mould described in the present invention is: (1) is at the wheel blanks spoke backform position processing through hole corresponding with the wheel rim junction.(2) hollow pipe caliber is suitable, that length shapes is certain is filled in the above-mentioned backform through hole, and spot welding is fixed.(3) backform is preheated to 450 ℃; Except that the hollow pipe place lead to the hole site of welding immediately; All the other positions all cover completely with double-deck high temperature resistant asbestic blanket, use the welding wire close with the backform material that through hole and periphery thereof are welded, and stop surplus and make it recover the preceding form of not boring.(4) backform is whole covers completely with double-deck high temperature resistant asbestic blanket, is allowed to condition at indoor slow air cooling to room temperature.(5) the backform welding position is carried out rubbing down, until reaching mold cavity surface roughness treatment requirement.
Usefulness of the present invention is: spoke and wheel rim junction shrinkage porosite alleviated obviously, and especially remarkable to the visible shrinkage porosite problem effect of semi-finished product after solving the wheel blanks machined.
Description of drawings
Fig. 1 is the sketch map of a kind of improved aluminum vehicle wheel casting mould of the present invention.
Among the figure: 1-backform, 2-hollow pipe, 3-wheel blanks.
The specific embodiment
As shown in Figure 1, a kind of improved aluminum vehicle wheel casting mould of the present invention and processing method thereof comprise backform 1, at backform 1 front wheel blanks, 3 spokes and wheel rim junction through hole are set, and are bumped into hollow pipe 2, and said hollow pipe 2 is close with the backform material.
The processing method of casting mould described in the present invention is: (1) is at the wheel blanks spoke backform position processing through hole corresponding with the wheel rim junction.(2) hollow pipe caliber is suitable, that length shapes is certain is filled in the above-mentioned backform through hole, and spot welding is fixed.(3) backform is preheated to 450 ℃; Except that the hollow pipe place lead to the hole site of welding immediately; All the other positions all cover completely with double-deck high temperature resistant asbestic blanket, use the welding wire close with the backform material that through hole and periphery thereof are welded, and stop surplus and make it recover the preceding form of not boring.(4) backform is whole covers completely with double-deck high temperature resistant asbestic blanket, is allowed to condition at indoor slow air cooling to room temperature.(5) the backform welding position is carried out rubbing down, until reaching mold cavity surface roughness treatment requirement.
Usefulness of the present invention is: spoke and wheel rim junction shrinkage porosite alleviated obviously, and especially remarkable to the visible shrinkage porosite problem effect of semi-finished product after solving the wheel blanks machined.
