Abstract
The utility model discloses a bearing cap insert of an engine cylinder body, which is a structure of two parallel cylindrical columns and a support plate transitionally connected to the columns as a whole. The support plate has a semicircular gap, at which a through hole parallel to the column is arranged; both sides of the support plate are provided with a groove. The structure is adopted to help the flow of liquid while casting, increasing the contact area of the main cap insert and the aluminum alloy, making drawbacks of air cavity and blowing space at the cutting place over the semicircular gap through a hole of the main cap insert, ensuring the full bond of the main cap insert and the aluminum alloy, improving the intensity of the main shaft hole, and improving the product quality of the lower engine cylinder body.
Description
Technical field
The utility model relates to engine cylinder-body, particularly relates to engine cylinder-body bearing cap mold insert.
Background technique
Existing vehicular engine cylinder body has adopted aluminium alloy cylinder in order to reduce engine weight.Yet aluminium alloy cylinder is installed the strength deficiency of the spindle hole position of bent axle, in order to improve intensity, now adopted in the bottom of the bearing cap that bent axle is installed and be cast into the spheroidal graphite cast iron main cover inlay pieces, main cover inlay pieces is that two parallel cylindrical vertical column reach the supporting plate-like all-in-one-piece structure that is connected with the column transition, this support plate has half circumferential notch, but the main cover inlay pieces of structure is cast into the lower cylinder body of engine in the aluminum alloy at present, produce the slit between main cover inlay pieces and aluminum alloy are easy, the below of main cover inlay pieces exists pore in the aluminum alloy, defectives such as trachoma, the quality of product can not get guaranteeing.
The model utility content
Technical problem to be solved in the utility model provides a kind of engine cylinder-body bearing cap mold insert that improves the quality of products, this engine cylinder-body bearing cap mold insert can fully combine with aluminum alloy, casting defects such as the pore that the below of elimination main cover inlay pieces exists, trachoma.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of engine cylinder-body bearing cap mold insert, be that two parallel cylindrical vertical column reach the supporting plate-like all-in-one-piece structure that is connected with the column transition, this support plate has half circumferential notch, it is characterized in that: the semicircle indentation, there of support plate is provided with the through hole parallel with column, and the two sides of support plate all is provided with groove.
Owing to adopt such structure, be convenient to flowing of liquid during casting, strengthened the area of contact of main cover inlay pieces and aluminum alloy, make defectives such as pore, sand holes be positioned at the cutting place, top of the semicircle breach through hole of main cover inlay pieces; Guarantee fully combining of main cover inlay pieces and aluminum alloy, improved the intensity of spindle hole, improved the quality of product of lower cylinder body of engine.
Described through hole is the oval shape, and corner is an arc transition, the flowability of liquid in the time of can improving casting.
Described each cylindrical vertical column is positioned at plane, semicircle breach opposite end and is provided with positioning hole.Can when casting, main cover inlay pieces be positioned on the mould exactly, thereby guarantee the tram of main cover inlay pieces at lower cylinder body of engine.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described;
Fig. 1 is the utility model engine cylinder-body bearing cap mold insert structural representation;
In Fig. 1,1, column; 2, column; 3, support plate; 4, positioning hole; 5, the upper surface of column; 6, the lower surface of column; 7, through hole; 8, groove.
Embodiment
As shown in Figure 1, engine cylinder-body bearing cap mold insert is a symmetrical structure, have two with the symmetry the parallel cylindrical body column 1 of center line, 2, two columns 1, it between 2 support plate 3, support plate 3 is a rectangular structure, half circumferential notch is arranged at its top, two columns 1,2 upper surface 5 is positioned at same plane, also be the upper surface of semicircle breach simultaneously, support plate 3 bottoms and two columns 1,2 is arc transition, two columns 1,2 lower surface 6 respectively has a positioning hole 4, the lowest part of the semicircle breach of support plate 3 has the through hole 7 of an oval shape, its corner is an arc transition, support plate 3 and two columns 1, the two sides of 2 changeover portion all has groove 8.
Aluminum alloy liquid flowed when the through hole of engine cylinder-body bearing cap mold insert oval shape helped casting, help the discharge of gas in the aluminum alloy liquid, casting defects such as the pore that the below of elimination main cover inlay pieces exists, trachoma, make defectives such as pore, sand holes be positioned at the cutting place, top of the semicircle breach through hole of main cover inlay pieces, the groove of support plate both sides is convenient to better combination of aluminum alloy and engine cylinder-body bearing cap mold insert, improve the intensity of spindle hole, improved the quality of product of lower cylinder body of engine.The lower surface of two columns has positioning hole, can when casting main cover inlay pieces be positioned on the mould exactly, thereby keep the tram of main cover inlay pieces at lower cylinder body of engine.
Claims (3)
1, a kind of engine cylinder-body bearing cap mold insert, be that two parallel cylindrical vertical column (1,2) reach the structure that the support plate (3) that is connected with column (1,2) transition forms one, this support plate (3) has half circumferential notch, it is characterized in that: the semicircle indentation, there of described support plate (3) is provided with the through hole (7) parallel with column (1,2), and two sides of support plate (3) all are provided with groove (8).
2, engine cylinder-body bearing cap mold insert according to claim 1 is characterized in that: described through hole (7) is the oval shape.
