Description
Technical field
The utility model belongs to cylinder casting technology field, and in particular to a kind of cylinder body water jacket stud structure.
Background technology
In cylinder blank production process, after external process, after cylinder barrel honing, inner wall of cylinder position often occurs shinny
Small cavity, this defect is gas hole defect, and the position that this stomata occurs is substantially distributed in the jacket core intermediate core position of bone and put, this position
Put and exactly deformed to improve jacket core, the jacket core stud position of placement.Because jacket core is in molten steel pouring course, stud
With core surface contact surface position, the resin in core is compared with slow combustion, and after waiting casting pouring to cool down, gas is sent by ladle
Wrap up in, gas can not arranged, and assemble to form stomata in cylinder barrel wall.Cylinder holes defect is vital for whole engine, is being started
In the operation process of machine, risk hidden danger is huge.
Utility model content
Avoid cylinder body gas hole defect in view of the shortcomings of the prior art, the utility model provides one kind, ensure product
Quality, improve yield rate, reduce production cost, cylinder body water jacket stud structure simple in construction.
To achieve these goals, the utility model is to realize by the following technical solutions：
A kind of cylinder body water jacket stud structure, it includes two supporting plates, keel and position limit arm, between described two supporting plates
Keel are set, are respectively provided with 22-26 hole in each supporting plate, described hole diameter 2mm, the one of each supporting plate
End is respectively provided with position limit arm, the rectangular shape of position limit arm, and the end of the position limit arm is to external expansion, the position limit arm width
2-3mm。
Preferably, its centrally disposed diameter 10mm of keel circular hole.
Preferably, 24 holes are set in its described each supporting plate.
Beneficial effect：The utility model preferably solves cylinder body gas hole defect, protected by the change of jacket core support structure
Product quality is hindered, has improved yield rate, reduced production cost, its is simple in construction, have accumulated for exploitation similar products abundant
Experience.
Brief description of the drawings
Describe the utility model in detail with reference to the accompanying drawings and detailed description；
Fig. 1 is front view of the present utility model.
Fig. 2 is Fig. 1 left view.
Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to the drawings and the specific embodiments, the utility model is expanded on further.
Referring to Figures 1 and 2, the utility model includes two supporting plates 1, keel 2 and position limit arm 3, described two supporting plates 1
Between set keel 2, the circular hole 4 of the centrally disposed diameter 10mm of keel 2.22-26 are respectively provided with each supporting plate 1
Hole 5, in the present embodiment, 24 holes 5 are set in each supporting plate 1.The diameter 2mm of described hole 5, each support
One end of plate 1 is respectively provided with position limit arm 3, the 3 rectangular shape of position limit arm, and the end of the position limit arm 3 is to external expansion, the limit
The position width of arm 3 is 2-3mm.
The utility model by stud position limit arm 3 change it is narrow shorten, and hole 5 is added in supporting plate 1, has both ensured water
The intensity of stud is covered, and adds the exposed area of core most possibly, beneficial to gas caused by resin burning in core
Body is discharged in time, so as to avoid the generation of cylinder body stomata.
The utility model preferably solves cylinder body gas hole defect, has ensured product by the change of jacket core support structure
Quality, yield rate is improved, reduce production cost, its is simple in construction, and abundant experience is have accumulated for exploitation similar products.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
