Description
Technical field
It the utility model is related to cylinder casting technical field, more particularly to a kind of structure for solving cylinder body stomata.
Background technology
The existing method for solving cylinder block water jacket position stomata does not form source of the gas generally by temperature is improved in gas
When, gas is discharged to outside molding sand by cylinder wall and molding sand；Sometimes also can be by simply being punched to core, to reduce gas
Source, gas is facilitated to be discharged fast into outside die cavity.
But the methods of by improving temperature, simply being punched to core, will not thoroughly eliminate the stomata at water jacket position.Especially
It is that water jacket wall is thin, the cylinder body that sand core of water jacket is high and clearance hole is distant from cylinder top surface, because iron liquid setting time is short, gas discharge
Route is grown, and will produce stomata.
In view of disadvantages described above, the utility model proposes a kind of structure for solving cylinder body stomata, reasonable in design, Neng Gouyou
Effect solves the above problems, and makes it more for practicality.
Utility model content
The defects of in order to overcome above-mentioned prior art, the purpose of this utility model are to provide a kind of knot for solving cylinder body stomata
Structure.
The utility model takes following technical scheme to realize：A kind of structure for solving cylinder body stomata, it includes thin
Wall cylinder body, clearance hole, the water jacket being arranged in Thin Wall Cylinder Blocks and cylinder deck, water jacket thin-walled, the first air-out needle, the second outlet
Pin, first air-out needle, the second air-out needle are connected to the cylinder deck, and second air-out needle is communicated in described shake out
Hole；The water jacket thin-walled top is provided with diagonal bar, and the diagonal bar starting point terminates at cylinder deck in clearance hole.
Further, the diagonal bar is connected with the clearance hole, cylinder deck.
Further, first air-out needle, the second outlet needle construction are identical.
The utility model has the advantages that in summary：The utility model is reasonable in design, simple in construction, tight
Gather, operation principle science is easy, securely and reliably, by increasing diagonal bar at Thin Wall Cylinder Blocks water jacket position to increase intensity and thickness
Degree；An exhaust passage is added between clearance hole and cylinder deck, greatly reduces casting wasted product rate and manufacturing cost.

Embodiment
Describe embodiments of the present invention in detail below with reference to embodiment, whereby to the present invention how application technology hand
Section solves technical problem, and the implementation process for reaching technique effect can fully understand and implement according to this.
As shown in figure 1, a kind of structure for solving cylinder body stomata, it includes Thin Wall Cylinder Blocks 4, clearance hole 8, is arranged on thin wall cylinder
Water jacket 5 and cylinder deck 6, water jacket thin-walled 3, the first air-out needle 1, the second air-out needle 2 in body 4, first air-out needle 1,
Second air-out needle 2 is connected to the cylinder deck 6, and second air-out needle 2 is communicated in the clearance hole 8.
As preferred scheme of the present utility model, the top of water jacket thin-walled 3 of the present utility model is provided with diagonal bar 7, described oblique
The starting point of muscle 7 terminates at cylinder deck 6 in clearance hole 8.The diagonal bar 7 of setting is act as：1st, the wall thickness of water jacket thin-walled 3 is increased
Add, add iron liquid setting time herein, being advantageous to gas caused by core has the sufficient time to discharge；2nd, first is added to go out
Exhaust passage between the air-out needle 2 of air tube 1 and second, make gas is smooth to be discharged by air-out needle outside cylinder body, substantially reduce
The generation of the position stomata of water jacket thin-walled 3；The percent defective of cylinder body is reduced, improves production efficiency, reduces cost, is created
Economic benefit and social benefit.
Diagonal bar 7 of the present utility model is connected with the clearance hole 8, cylinder deck 6；First air-out needle 1, the second air-out needle
2 structures are identical.
Operation principle of the present utility model is：When iron liquid pours the core die cavity of Thin Wall Cylinder Blocks 4, start to toast water jacket 5, gas
Body will discharge upwards, smoothly be discharged gas from the first air-out needle 1 and the second air-out needle 2 by diagonal bar 7, operation principle is simple
Science.
The utility model is reasonable in design, simple in construction, compact, and operation principle science is easy, securely and reliably, by
The position of 4 water jacket of Thin Wall Cylinder Blocks 5 increases diagonal bar 7 and increases intensity and thickness；Added between clearance hole 8 and cylinder deck 6
One exhaust passage, greatly reduces casting wasted product rate and manufacturing cost.
Described above is embodiment of the present utility model, therefore all constructions according to described in present utility model application scope, feature
And the equivalent change or modification that principle is done, it is included in the utility model patent application range.
