Abstract

The utility model discloses a novel gas compressor cylinder body. A top riser sand core is positioned above a casting; a water jacket sand core is positioned in the casting; an internal sand core A is positioned in the water jacket sand core; internal sand cores B are positioned on the two sides of the top riser sand core; the internal sand cores B are positioned above a steel core on the two sides; an oblique loose core on the two sides penetrates through a hole in the casting; the steel core on the two sides penetrates through the hole in the casting; the oblique loose core on the two sides is connected with the steel core on the two sides; a movable block is positioned on the lower side of the casting; a bottom core is positioned at the lower end of the casting. According to the novel compressor cylinder body, sand with big gas-forming amount and high strength is adopted for manufacturing the water jacket sand core; the surfaces of the sand cores are coated with alcohol-based zircon powder coating, fully roasted aluminum powder for degreasing is added in the coating, so that the gas produced by the sand is prevented from being exhausted, certain chilling effect is achieved, and shrinkage porosity of the casting is prevented.

Description

A kind of new gas compressor casing

Technical field

the utility model relates to foundry goods field, especially a kind of new gas compressor casing.

Background technology

The thick large flange at prior art cylinder body two ends easily produces shrinkage porosite or shrinkage cavity, top and the thick large part of both sides cylinder sleeve end face are because installing screw thread, inner convex platform needs feeding, therefore need routinely very large complicated running and feeding system, foundry goods yield rate will only have 35% left and right like this, have a strong impact on the raising of benefit; Due to the existence of sandwich, sand core of water jacket cooling velocity is slow, and sand core of water jacket is except several circles can lead to outside exhaust simultaneously, and other positions are all wrapped in foundry goods, therefore the exhaust of core will be difficult to control, and so just very easily cause core inner chamber to form large pore; Therefore need existing system to improve.

Utility model content

For the problems referred to above, the utility model aims to provide a kind of new gas compressor casing.

For realizing this technical purpose, scheme of the present utility model is: a kind of new gas compressor casing, by top riser core, internal cores A, internal cores B, two skew backs are loosed core, both sides steel core, loose piece, end core, sand core of water jacket and foundry goods composition, described top riser core is positioned at foundry goods top, described sand core of water jacket is positioned at foundry goods inside, described internal cores A is positioned at sand core of water jacket inside, described internal cores B is positioned at top riser core both sides, described internal cores B is positioned at steel core top, both sides, described two skew backs are loosed core through the hole on foundry goods, described both sides steel core is through the hole on foundry goods, described two skew backs are loosed core and are connected with both sides steel core, described loose piece is positioned at the downside of foundry goods, core of the described end is positioned at foundry goods lower end.

As preferably, described foundry goods is provided with aperture, and the ledge of described sand core of water jacket inserts in aperture.

As preferably, described foundry goods bottom is structure chamber, in the middle of described foundry goods top, is made up of complicated water-cooling channel, has multiple isolation clip layer structures between described water-cooling channel.

Compared with prior art, the beneficial effects of the utility model are: select the sand that gas forming amount is large, intensity is high to make sand core of water jacket, surface at core is coated with alcohol zircon flour coating, and in coating, add the aluminium powder of the degreasing of fully toasting, both can prevent that the gas that core occurs from discharging, can play again certain chill effect, thereby prevent the formation of shrinkage porosite in foundry goods.The utility model adopts metal pattern and the comprehensive casting method of core, not only economy but also can improve the quality of foundry goods.

Detailed description of the invention

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, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art 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. 1-6, in the utility model embodiment, a kind of new gas compressor casing, by top riser core 1, internal cores A2, internal cores B3, two skew backs loose core 4, both sides steel core 5, loose piece 6, end core 7, sand core of water jacket 8 and foundry goods 9 form, described top riser core 1 is positioned at foundry goods 9 tops, described sand core of water jacket 8 is positioned at foundry goods 9 inside, described internal cores A2 is positioned at sand core of water jacket 8 inside, described internal cores B3 is positioned at top riser core 1 both sides, described internal cores B3 is positioned at both sides steel core 5 tops, described two skew backs loose core 4 through the hole on foundry goods 9, described both sides steel core 5 is through the hole on foundry goods 9, described two skew backs are loosed core and 4 are connected with both sides steel core 5, described loose piece 6 is positioned at the downside of foundry goods 9, core of the described end 7 is positioned at foundry goods 9 lower ends.

As preferably, described foundry goods 9 is provided with aperture 10, and the ledge of described sand core of water jacket 8 inserts in aperture 10.

As preferably, described foundry goods 9 bottoms are structure chamber, and described foundry goods is made up of complicated water-cooling channel in the middle of 9 tops, has multiple isolation clip layer structures between described water-cooling channel.

Operation principle of the present utility model is: select the sand that gas forming amount is large, intensity is high to make sand core of water jacket 8, surface at core is coated with alcohol zircon flour coating, and in coating, add the aluminium powder of the degreasing of fully toasting, both can prevent that the gas that core occurs from discharging, can play again certain chill effect, thereby prevent the formation of shrinkage porosite in foundry goods 9.The utility model adopts metal pattern and the comprehensive casting method of core, not only economy but also can improve the quality of foundry goods 9.

To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example 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 instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any Reference numeral in claim should be considered as limiting related claim.
