Abstract
The utility model discloses an aluminium alloy cylinder. The aluminium alloy cylinder comprises a cylinder body, a double round hole, a projection body, an upper opening, a pouring gate, a middle pressure cavity, a high pressure cavity, a low pressure cavity and a lower opening, wherein the double round hole is formed in the lower part casing of the cylinder body; the outlet of the middle pressure cavity is formed in the double round hole; the inlet of the middle pressure cavity is formed in the lower opening; the pouring gate is located on the lower opening; the projection body is located on the middle part housing of the cylinder body; the low pressure cavity is located on the upper opening. The aluminium alloy cylinder adopts a reasonable structure and technology, not only is very good in sealing performance and pressure-resistant performance, but also is very high in production efficiency and qualification rate.
Description
Technical field
The utility model relates to cylinder body technical field, is specially a kind of aluminium alloy cylinder.
Background technology
It is very extensive that cylinder body is used as a kind of conventional machine components, seal and anti-pressure ability are the fine or not important indicators of making to weigh a cylinder body, but in the market this kind of cylinder body is due to the irrationality of structure, in casting and use procedure, all run into a lot of problems, in the process of manufacturing, defect rate is high, in use seal and anti-pressure ability are not fine, and for this reason, we propose a kind of aluminium alloy cylinder.
Utility model content
The purpose of this utility model is to provide a kind of aluminium alloy cylinder, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of aluminium alloy cylinder, comprise cylinder main body, double circular hole, projection body, suitable for reading, cast gate, middle pressure chamber, high pressure chest, low-pressure cavity and end opening, described double circular hole is positioned on the lower case of cylinder main body, the outlet in described middle pressure chamber on double circular hole, entrance on end opening, described cast gate is positioned on end opening; Described projection body is positioned in the middle housing of cylinder main body; Described low-pressure cavity be positioned at suitable for reading on.
Preferably, described cast gate has four, and is uniformly distributed.
Preferably, described projection body is provided with high pressure chest.
During production, the process using of aluminium alloy cylinder erects pouring type, relative altitude is higher, cast gate below, top flange belongs to thick large part (thickness 32mm), intermediate means wall thickness 8mm, foundry goods erects to pour into a mould, relative altitude is higher, feeding difficulty, flange upper screwed hole often leaks gas, the high pressure chest on top particularly, do not allowed gas leak phenomenon, cast gate is difficult to feeding, and to high pressure chest, (high pressure chest is shaped by core, center macropore is shaped by steel core, between core and large steel core, there is thickness 5mm height 47mm thin-walled), adopted the precoated sand that a kind of amount of stored heat is large to make sand cover for this reason, play the effect of insulated feeder, improve feeding effect, the little rectangular core top at the large steel core of patrix top, accumulation of heat effect due to core, cause temperature field irrational distribution, there is shrinkage porosite, the same insulated feeder effect that adopts sand cover, change thermal center position, thoroughly solved shrinkage defect herein, the middle pressure chamber of foundry goods, high pressure chest and low-pressure cavity have core to be shaped, the feature of low pressure casting is that aluminium water is under the effect of air pressure, fill from lower to upper type, feeding from lower to upper, use a kind of antiseized sand coating (to include graphite powder, aluminium powder, waterglass, the compositions such as water), brush at the position that easily produces scab at core, can be good at having solved scab problem.
Compared with prior art, the beneficial effects of the utility model are: this aluminium alloy cylinder, adopted rational structure and technique, not only seal and anti-pressure ability are all fine, and production efficiency and qualification rate all very high.
Accompanying drawing explanation
Fig. 1 is that the utility model is placed structural representation vertically;
Fig. 2 is the utility model traverse structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, in the utility model embodiment, a kind of aluminium alloy cylinder, comprise cylinder main body 1, double circular hole 2, projection body 3, suitable for reading 4, cast gate 5, middle pressure chamber 6, high pressure chest 7, low-pressure cavity 8 and end opening 9, described double circular hole 2 is positioned on the lower case of cylinder main body 1, the outlet in described middle pressure chamber 6 on double circular hole 2, entrance on end opening 9, described cast gate 5 is positioned on end opening 9, described cast gate 5 has four, and is uniformly distributed; Described projection body 3 is positioned in the middle housing of cylinder main body 1, and described projection body 3 is provided with high pressure chest 7; Described low-pressure cavity 8 is positioned on suitable for reading 4.
During production, the process using of aluminium alloy cylinder erects pouring type, relative altitude is higher, cast gate below, top flange belongs to thick large part (thickness 32mm), intermediate means wall thickness 8mm, foundry goods erects to pour into a mould, relative altitude is higher, feeding difficulty, flange upper screwed hole often leaks gas, the high pressure chest 7 on top particularly, do not allowed gas leak phenomenon, cast gate 5 is difficult to feeding and is shaped by core to high pressure chest 7(high pressure chest 7, center macropore is shaped by steel core, between core and large steel core, there is thickness 5mm height 47mm thin-walled), adopted the precoated sand that a kind of amount of stored heat is large to make sand cover for this reason, play the effect of insulated feeder, improve feeding effect, the little rectangular core top at the large steel core of patrix top, accumulation of heat effect due to core, cause temperature field irrational distribution, there is shrinkage porosite, the same insulated feeder effect that adopts sand cover, change thermal center position, thoroughly solved shrinkage defect herein, the middle pressure chamber 6 of foundry goods, high pressure chest 7 and low-pressure cavity 8 have core to be shaped, the feature of low pressure casting is that aluminium water is under the effect of air pressure, fill from lower to upper type, feeding from lower to upper, use a kind of antiseized sand coating (to include graphite powder, aluminium powder, waterglass, the compositions such as water), brush at the position that easily produces scab at core, can be good at having solved scab problem.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
