Abstract
The utility model provides a kind of running gate system of wheel hub, wheel hub external structure is divided into first step, second step, flange and straight barrel successively, internal run-through is provided with installing positions of bearings, flange is provided with installation groove, second step cylindrical is provided with feeding head, and 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; Feeding head root and second step are also provided with fracture port.Pouring position moves on to and needs feeding position by the utility model foundry goods, move on to above the second step on flange by feeding head, with a feeding head, by direct for feeding feeding on second step, due to the continuity of sprue and cross gate, poured into a mould foundry goods by feeding head, shrinkage defect is eliminated substantially, and result reaches product requirement.
Description
Technical field
The utility model relates to the cast structure of auto parts and components, specifically a kind of running gate system of wheel hub.
Background technology
Wheel hub external structure in auto parts and components is 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 Design of Runner System of wheel hub generally adopts following scheme:
Scheme one: in order to have a relative feeding to the second step 2 on flange 3 both sides with straight barrel 4, especially can there is shrinkage cavity/pine with the root of step 2 in flange 3, a hot feeding head is provided with at this wheelboss flange 3 cylindrical place of cast so can adopt, make molten iron from this by realizing cast, through dissecting, result checks that internal shrinkage/loose ratio reaches 80%, the disqualification rate of product is too high.
Scheme two: adopt flange 3 cylindrical place to be laid with three feeding heads, and enter molten iron realization cast from three feeding heads, 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 place to be provided with three feeding heads, and pour into a mould from three feeding heads, chill (namely at scheme two basis chill up and down) 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 does not reach the requirement of 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 utility model, in order to eliminate internal flaw, improves yield rate, saves production cost, increase economic efficiency, the special running gate system proposing a kind of wheel hub.
The technical solution of the utility model is for this reason, a kind of running gate system of wheel hub, wheel hub external structure is divided into first step, second step, flange and straight barrel successively, 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 improvement is: feeding head root and flange root are provided with spacing, and this spacing is 3-5mm.
Further improvement is: feeding head root and second step are also provided with fracture port.
Beneficial effect:
Pouring position moves on to and needs feeding position by the utility model foundry goods, move on to above the second step on flange by feeding head, with a feeding head, by direct for feeding feeding on second step, due to the continuity of sprue and cross gate, poured into a mould foundry goods by feeding head, shrinkage defect is eliminated substantially, and result reaches product requirement.
Feeding head root and flange root are provided with spacing, eliminate the pouring defect of flange root, ensure the integrality of flange root, and the integrality of following process, and the setting of 3-5mm not only meets required distance, also overcomes pouring defect to greatest extent.
The setting of fracture port ensure that the feeding effect of feeding head, and the wheel hub simultaneously after cast also has a complete profile.
Accompanying drawing explanation
Fig. 1 is the product schematic diagram of wheel hub.
Fig. 2 is the using state schematic diagram of the utility model casting system.
In figure, 1 is first step, and 2 is second steps, and 3 is flanges, and 4 is straight barrels, and 5 is installing positions of bearings, and 6 is install groove, and 7 is feeding heads, and 8 is cross gates, and 9 is sprues, and 10 is fracture ports.
Detailed description of the invention
The utility model as shown in Figure 2.
A kind of running gate system of wheel hub, wheel hub external structure is 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, second step 2 cylindrical is provided with feeding head 7, and feeding head 7 connects sprue 9 by cross gate 8 again.
Feeding head 7 root and flange 3 root are provided with spacing, and this spacing is 3-5mm.
Feeding head 7 root and second step 2 are also provided with fracture port 10.
