Description
Technical field
The present invention relates to casting technology field, more particularly to a kind of method that chill is fixed on mould inclined-plane is main suitable
For being the method that directly outer cold iron is set on the inclined-plane in casting die in casting Technology Design.
Background technology
In foundry engieering, the shrinkage porosite tendency of spheroidal graphite cast-iron and steel-casting is big, and key position and thermal center concentrate position typically to need
Chill and rising head are wanted to improve Filling Processes of Castings cooling procedure, reduces shrinkage porosite, shrinkage cavity.And chill is set to reach expected ideal
Effect, its putting position are extremely important.
General in the prior art to position chill using magnet, the method is only applicable to metal die and chill lighter in weight
Situation.And the chill or wood mold coupled to heavier-weight, chill can be caused to shift or can not consolidate completely due to magnetic force deficiency
The problem of determining.If increasing magnetic force using the method for increase magnet quantity, molding difficulty, metal die or cold can be caused again
Iron such as is magnetized at the various problems, is unfavorable for later stage production.
The content of the invention
The present invention is for the problem of chill method to set up is present in the prior art, there is provided one kind is fixed cold on mould inclined-plane
The method of iron, to set rational chill size, putting position and localization method, so that chill gives full play to using effect.
The object of the present invention is achieved like this, a kind of method that chill is fixed on mould inclined-plane, comprises the following steps：
(A）First determine need set chill mould inclined-plane, and according to corresponding to the mold slanted face casting thermal center or
Wall thickness dimension determines the thickness a of chill；
(B) and then the mould inclined-plane and the angle α of horizontal direction are measured, according to formula（1）、（2）、（3）Determine chill
Length b scope：
Formula（1）,
Formula（2）,
Formula（3）；
Using the above method, the minimum length size of the chill of design, the center of gravity line of chill and the mold slanted put can be made
Face joining falls in the equitant surface in mould inclined-plane put in chill bottom surface with it, so as to improve on chill and mould inclined-plane
The stability put；
（C）According to（B）The chill length determined is walked, draws the trace of chill position in the design attitude of chill, and spray
It is coated with the good paint of performance；By accurately drawing the trace of chill position in this step, it is ensured that postorder is accurately put
Chill position；
（D）Two non-cap steel nails are fixed under the trace of chill position with respect to the both sides of chill center of gravity line along sideline to be used to hold in the palm
Firmly chill；In this step, by fixing non-cap steel nail on the lower edge side for putting chill position, it is possible to achieve chill during back-up sand jolt ramming
The fixation of position；
（E）Chill is put according to the trace of chill position before molding and core making production, puddle mixer quicksand is then started, treats molding sand
After consolidation, model sand mold is played, applies coating in sand mold mold cavity surface, and steel nail ledge is covered in the hole that mold cavity surface leaves
It is smooth, then carry out subsequent processing flow.By after molding in this step, non-cap steel nail is in the hole that the mold cavity surface of sand mold leaves
Covered by coating it is smooth, to eliminate influence of the steel nail to die cavity.
Further, the thickness a of the chill is 0.6-0.8 times of casting thermal center.
Further, the non-cap steel nail exposes mould chamfered surface 2-3mm.
Further, the step (E）In, being applied at twice when applying coating, first pass uses osmosis type coating,
Baume degrees is 0-60；Second time use surface type coating, Baume degrees 45-55.
Brief description of the drawings
Fig. 1 is the schematic diagram that chill method is fixed on the mould inclined-plane of the present invention.
Embodiment
The method that the invention will now be described in detail with reference to the accompanying drawings.
As shown in figure 1,（A）First according to casting structure requirement, it is necessary to chill 2 be set on mould inclined-plane 1, according to the inclined-plane
The wall thickness and thermal center size, the thickness for determining the chill that the inclined-plane need to be placed of place's casting tool are a, and wherein a value presses casting
0. 6-0.8 times of thermal center size.(B) and then above-mentioned mould inclined-plane 1 and the angle α of horizontal direction are measured, according to formula（1）、
（2）、（3）Determine the length b of chill minimum length：
Formula（1）,
Formula（2）,
Formula（3）；
Using the above method, the minimum length size of the chill of design, the center of gravity line of chill 2 and the mold slanted put can be made
The joining in face 1 falls in the equitant surface in mould inclined-plane that G is put in chill bottom surface with it, so as to improve chill and mold slanted
The stability put on face.（C）According to（B）The chill length determined is walked, the print of chill position is drawn in the design attitude of chill
Mark, and it is coated with the paint of dependable performance；In this step, applied at twice when applying coating, first pass is applied using osmosis type
Material, Baume degrees 0-60；Second time use surface type coating, Baume degrees 45-55.
By accurately drawing the trace of chill position in this step, it is ensured that postorder accurately puts chill position.（D）
The lower of trace in chill position fixes two non-cap steel nails 3 for holding chill along sideline with respect to the both sides of chill center of gravity line,
The length that wherein non-cap steel nail 3 exposes the surface of mould inclined-plane 2 is 2-3mm；In this step, by putting the following of the position of chill 2
Non-cap steel nail 3 is fixed along side, it is possible to achieve the fixation of the position of chill 2 during back-up sand jolt ramming, so as to prevent chill from being glided along inclined-plane.
（E）Chill 2 is put according to the trace of chill position before molding and core making production, then starts puddle mixer quicksand, after molding sand consolidation,
Model sand mold is played, coating is applied in sand mold mold cavity surface, and steel nail ledge is smooth in the hole that mold cavity surface leaves covering, so
Subsequent processing flow is carried out afterwards.By after molding in this step, non-cap steel nail passes through painting in the hole that the mold cavity surface of sand mold leaves
Material covering is smooth, to eliminate influence of the steel nail to die cavity.
