Abstract
The utility model discloses a gravity casting mould of an aluminum alloy motorcycle hub. The gravity casting mould of the aluminum alloy motorcycle hub comprises an upper mould, a lower mould and a sand core, wherein a forming mould for casting the hub is arranged between the upper mould and the lower mould; the gravity casting mould of the aluminum alloy motorcycle hub is characterized in that the upper mould is provided with an aluminum water injection straight pouring gate which extends downwards; the end of the straight pouring gate is connected with a cross pouring gate which forms a certain buffering angle with the straight pouring gate. According to the gravity casting mould of the aluminum alloy motorcycle hub, the casting defects of oxide skins, included slag and the like of aluminum motorcycle wheels at the spokes or middle hubs are greatly reduced, the pass yield of the product is improved, in particular, the first pass yield of the coating process is improved, the rework frequency is decreased, the loss of oil paint (powder) is decreased and then the production cost is reduced.
Description
Technical field
The utility model relates to Al-alloy motorcycle wheel manufacturing technology field, relates to more specifically a kind of gravity casting die of Al-alloy motorcycle wheel hub.
Background technology
Al-alloy motorcycle wheel construction is comprised of wheel rim, spoke and middle hub.High-grade motorcycle is the aluminum-alloy wheel of equipped hollow generally, and middle hub portion is often taller and bigger.Aluminum current alloy wheel generally adopts the technological forming of center of gravity cast.Fig. 1 is center of gravity casting mold schematic diagram.During cast, aluminium water injects in mold cavity b from trumpet assembly a under the effect of gravity, because aluminium water filling velocity is uncontrolled, easily produce the surface that the impurity such as a large amount of oxide skin, slag inclusion are attached to middle hub, middle hub is taller and bigger, aluminium water drop is larger, and the defects such as formed oxide skin, slag inclusion are more serious for a long time.At coating process, due to casting flaws such as oxide skin or slag inclusions, surface spraying paint or powder are after solidifying baking, and surface very easily produces bubble and lost efficacy.Product must again spray after surface finish again, often qualified through the ability of repeatedly doing over again.This not only paints, the consumption of powder increases, and causes the rising of cost, also can extend manufacture cycle, and reduces the effective capacity of equipment.Even because do over again often, affect coating performance and cause product rejection.
Summary of the invention
The purpose of this utility model is exactly provide in order to solve the deficiency of prior art a kind of simple in structure, easy to operate, improves product percent of pass, reduces the loss of raw material, the gravity casting die of the Al-alloy motorcycle wheel hub reducing production costs.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of gravity casting die of Al-alloy motorcycle wheel hub, comprise upper die and lower die and core, between upper die and lower die, be provided with the shaping mold cavity of casting wheel hub, it is characterized in that, described patrix is provided with to the aluminium water of downward-extension and injects sprue, and sprue end is connected with the cross gate that becomes necessarily to cushion angle with it.
As further illustrating of such scheme, the shaping mold cavity top of described casting wheel hub is provided with rising head, the bottom of rising head is connected with ingate, wheel hub shaping mold cavity comprises drop center portion, spoke portion and middle hub, and ingate connects drop center portion, spoke and middle hub successively, makes to inject the aluminium water of sprue, through cross gate, from the ingate of rising head bottom, enter the wheel rim of foundry goods, then aluminium water enters middle hub from spoke again, completes the cavity filling process of whole casting.
Described bumper angle is 60-120 degree, and in conjunction with the sectional dimension that regulates running channel, adjustable filling velocity is to meet suitable casting technique requirement.
The arranged outside of described patrix and patrix has side form, between upper die and lower die, by securing member, is fixed.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts by sprue being set at patrix and becoming the cross gate of certain bumper angle with sprue, can effectively improve the defects such as oxide skin that Al-alloy motorcycle wheel produces at casting process, slag inclusion, minimizing due to casting flaws such as oxide skins, the raising of qualification rate, especially first-time qualification rate that can greatly improve coating process is remarkable.

Fig. 2 is structural representation of the present utility model.
Description of reference numerals: 1, patrix 2, counterdie 3, side form 4, core 5, sprue 6, cross gate 7, rising head 8, ingate 9, wheel hub shaping mold cavity.
The specific embodiment
Below in conjunction with specific embodiment, specific embodiments of the present utility model is described in further detail.
As shown in Figure 2, the gravity casting die of a kind of Al-alloy motorcycle wheel hub of the utility model, comprise patrix 1, counterdie 2, side form 3, side form 3 is enclosed in the outside of patrix 1 and patrix 2, between upper die and lower die, by securing member, fixed, be provided with the shaping mold cavity of casting wheel hub between patrix 1, counterdie 2, shaping mold cavity middle part is provided with core 4, patrix is provided with to the aluminium water of downward-extension and injects sprue 5, and sprue end is connected with the cross gate 6 that becomes necessarily to cushion angle with it.The shaping mold cavity top of casting wheel hub is provided with rising head 7, the bottom of rising head 7 is connected with ingate 8, wheel hub shaping mold cavity 9 comprises drop center portion, spoke portion and middle hub, ingate connects drop center portion, spoke and middle hub successively, make to inject the aluminium water of sprue, pass through cross gate, then from the ingate of rising head bottom, enter the wheel rim of foundry goods, then aluminium water enters middle hub from spoke, completes the cavity filling process of whole casting.Bumper angle is 90 degree, and in conjunction with the sectional dimension that regulates running channel, adjustable filling velocity is to meet suitable casting technique requirement.Adopt after this technology, the qualification rate of coating process rises to more than 90%.
In casting process, aluminium water injects sprue, passes through cross gate, then from the ingate of rising head bottom, enters the wheel rim of foundry goods, and then aluminium water enters middle hub from spoke, completes the cavity filling process of whole casting.In this process, aluminium water can slow down flow velocity (90 degree buffering) while entering cross gate from sprue, and by the sectional dimension of appropriate design ingate, adjustable filling velocity is to meet suitable casting technique requirement.And center pouring technology does not have the buffering of cross gate, filling velocity is uncontrollable.Press Casting Principle, fill type more steady, the defect that produces oxide skin, slag inclusion is just fewer, and the proportion of oxide skin, slag inclusion is less than aluminium, when liquid, floats on the surface.Therefore, the cross gate of limit pouring technique can also effectively stop that the oxide skin that cavity filling process produces enters foundry goods, the oxide skin that ingate produces mainly concentrates at emits port part, thereby make foundry goods, especially in the middle of the casting flaws such as oxide skin, slag inclusion at hub position greatly reduce, the surface quality of hub cast obviously improves.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
