Abstract
The invention provides a kind of running gate system of wheel hub, in wheel hub external structure, be divided into successively first step, second step, flange and straight barrel, internal run-through is provided with installing positions of bearings, flange is provided with installation groove, on second step cylindrical, be provided with feeding head, feeding head is connected with sprue by cross gate again; Feeding head root and flange root are provided with spacing, and this spacing is 3-5mm; On feeding head root and second step, be also provided with fracture port. Foundry goods of the present invention moves on to pouring position to need feeding position, move on to above the second step on flange by feeding head, with a feeding head, by direct feeding feeding to second step, due to the continuity of sprue and cross gate, by feeding head, foundry goods is poured into a mould, shrinkage defect is eliminated substantially, and result reaches product requirement.
Description
Technical field
The present invention relates to the cast structure of auto parts and components, specifically a kind of running gate system of wheel hub.
Background technology
In wheel hub external structure in auto parts and components, be divided into successively first step 1, second step 2, flange 3 and straight barrel 4, internal run-through is provided with installing positions of bearings 5, and flange is provided with installs groove 6. As shown in Figure 1.
At present, under conventional method, the following scheme of the general employing of the Design of Runner System of wheel hub:
Scheme one: for the second step 2 on flange 3 both sides and straight barrel 4 are had to a relative feeding, especially can there is shrinkage cavity/pine with the root of step 2 in flange 3, so can adopt at these wheelboss flange 3 cylindrical places of cast and be provided with a hot feeding head, molten iron is poured into a mould by realization from this, result checks that through dissecting internal shrinkage/loose ratio reaches 80%, and the disqualification rate of product is too high.
Scheme two: adopt flange 3 cylindrical places to be laid with three feeding heads, and enter molten iron from three feeding heads and realize cast, now internal shrinkage problem makes moderate progress, but ratio still reaches 50%, and the disqualification rate of product is still higher.
Scheme three: adopt flange 3 cylindrical places to be provided with three feeding heads, and pour into a mould from three feeding heads, chill (at the scheme two upper and lower chills in basis) under second step root simultaneously, result still has shrinkage cavity/loose defect through dissecting, position is mainly distributed in region between chill and chill, though area is less, but still the requirement that does not reach product, and ratio still has 30%, the disqualification rate of product is still higher.
Above three kinds of traditional schemes, although to the eye less than defect, shrinkage cavity after tangent plane/loose defect is obvious.
Summary of the invention
The present invention, in order to eliminate internal flaw, improves yield rate, saves production cost, and increases economic efficiency, the special running gate system that proposes a kind of wheel hub.
Technical scheme of the present invention is for this reason, a kind of running gate system of wheel hub, in wheel hub external structure, be divided into successively first step, second step, flange and straight barrel, internal run-through is provided with installing positions of bearings, flange is provided with installation groove, it is characterized in that: on second step cylindrical, be provided with feeding head, feeding head is connected with sprue by cross gate again.
Further improve and be: feeding head root and flange root are provided with spacing, and this spacing is 3-5mm.
Further improve and be: on feeding head root and second step, be also provided with fracture port.
Beneficial effect:
Foundry goods of the present invention moves on to pouring position to need feeding position, move on to above the second step on flange by feeding head, with a feeding head, by direct feeding feeding to second step, due to the continuity of sprue and cross gate, by feeding head, foundry goods is poured into a mould, shrinkage defect is eliminated substantially, and result reaches product requirement.
Feeding head root and flange root are provided with spacing, have eliminated the pouring defect of flange root, ensure the integrality of flange root, and the integrality of following process, and the setting of 3-5mm has not only met required distance, has also overcome to greatest extent pouring defect.
Fracture port the feeding effect that has ensured feeding head is set, the wheel hub after cast also has a complete profile simultaneously.
Brief description of the drawings
Fig. 1 is the product schematic diagram of wheel hub.
Fig. 2 is the use view of casting system of the present invention.
In figure, 1 is first step, the 2nd, and second step, the 3rd, flange, the 4th, straight barrel, the 5th, installing positions of bearings, the 6th, groove is installed, the 7th, feeding head, the 8th, cross gate, the 9th, sprue, the 10th, fracture port.
Detailed description of the invention
The present invention as shown in Figure 2.
A kind of running gate system of wheel hub, in wheel hub external structure, be divided into successively first step 1, second step 2, flange 3 and straight barrel 4, internal run-through is provided with installing positions of bearings 5, flange 3 is provided with installs groove 6, on second step 2 cylindricals, be provided with feeding head 7, feeding head 7 connects sprue 9 by cross gate 8 again.
Feeding head 7 roots and flange 3 roots are provided with spacing, and this spacing is 3-5mm.
On feeding head 7 roots and second step 2, be also provided with fracture port 10.
Claims (3)
