The utility model relates to a kind of little four-way, comprise: vertical pipeline and tilted tube, described vertical pipeline and the outside integrally casting of tilted tube, inner connection, described vertical pipeline comprises two sections, epimere is coaxially connected with hypomere, the internal diameter of epimere is greater than the internal diameter of hypomere, tilted tube intersects with vertical pipeline epimere and inside is connected, the internal diameter of vertical pipeline epimere and tilted tube is 11.6mm, the internal diameter of vertical pipeline hypomere is 7mm, the wall thickness of tilted tube and vertical pipeline is 2.5 ~ 2.6mm, this little four-way, by rationally increasing wall thickness, larger impact force can be born, thus can accelerate to pour into a mould flow velocity, enhance productivity, reduce cost of production, reasonable increase wall thickness, reduce reject rate, yield rate is by 40 ~ 50%, rise to 80 ~ 90%, improve the surface finishment of product simultaneously.
Description
Technical field:
The utility model relates to precision casting technology field, particularly the little four-way of one.
Background technique:
Little four-way products application is extensive, fast-selling overseas, but unreasonable owing to designing, and mainly wall thickness design is unreasonable, cause cast reject rate high, yield rate is lower, and cost of production is higher, and delivery date is long, the demand of client can not be met, now little four-way product is improved, suitably increase wall thickness, promote yield rate.
Model utility content:
The purpose of this utility model is to provide a kind of little four-way, by suitably increasing wall thickness, improving the yield rate of little four-way product, reducing cost of production simultaneously.
To achieve these goals, the utility model adopts following technological scheme: a kind of little four-way, comprise: vertical pipeline and tilted tube, described vertical pipeline and the outside integrally casting of tilted tube, inner connection, described vertical pipeline comprises two sections, epimere is coaxially connected with hypomere, the internal diameter of epimere is greater than the internal diameter of hypomere, tilted tube intersects with vertical pipeline epimere and inside is connected, the internal diameter of vertical pipeline epimere and tilted tube is 11.6mm, and the internal diameter of vertical pipeline hypomere is 7mm, and the wall thickness of tilted tube and vertical pipeline is 2.5 ~ 2.6mm.
On described vertical pipeline, segment length is 52mm, under vertical pipeline, segment length is 20.4mm, the length of tilted tube is 44mm, and the intersection point of tilted tube and vertical pipeline epimere inner diameter central line is 22mm to the distance of the tilted tube mouth of pipe, and the distance to the vertical pipeline epimere mouth of pipe is 22mm.
Between described tilted tube and vertical pipeline in angle of 45 degrees.
Relative to prior art, the utility model has the following advantages:
1, the wall thickness of tilted tube and vertical pipeline is 2.5 ~ 2.6mm, wall thickness has carried out rational increase by original 1.9mm, larger impact force can be born, thus can accelerate to pour into a mould flow velocity, enhance productivity, reduce cost of production, reasonable increase wall thickness, reduce reject rate, yield rate is by 40 ~ 50%, rise to 80 ~ 90%, improve the surface finishment of product simultaneously.
2, increase external diameter and the wall thickness of product, keep the internal diameter of product constant, tilted tube and vertical pipeline are in angle of 45 degrees simultaneously, increase circulation and the reversing force of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, tilted tube; 2, epimere; 3, hypomere.
Embodiment
Below in conjunction with embodiment, the utility model is described in more detail.
As shown in Figure 1, a kind of little four-way, comprise: vertical pipeline and tilted tube 1, described vertical pipeline and the outside integrally casting of tilted tube 1, inner connection, described vertical pipeline comprises two sections, epimere 2 is coaxially connected with hypomere 3, the internal diameter of epimere 2 is greater than the internal diameter of hypomere 3, tilted tube 1 intersects with vertical pipeline epimere 2 and inside is connected, vertical pipeline epimere 2 is 11.6mm with the internal diameter of tilted tube 1, and the internal diameter of vertical pipeline hypomere 3 is 7mm, and tilted tube 1 is 2.5 ~ 2.6mm with the wall thickness of vertical pipeline.
Described vertical pipeline epimere 2 length is 52mm, vertical pipeline hypomere 3 length is 20.4mm, the length of tilted tube 1 is 44mm, and the intersection point of tilted tube 1 and vertical pipeline epimere 2 inner diameter central line is 22mm to the distance of tilted tube 1 mouth of pipe, and the distance to vertical pipeline epimere 2 mouth of pipe is 22mm.
Between described tilted tube 1 and vertical pipeline in angle of 45 degrees.
Tilted tube 1 is 2.5mm with the wall thickness of vertical pipeline, wall thickness has carried out rational increase by original 1.9mm, larger impact force can be born, thus can accelerate to pour into a mould flow velocity, enhance productivity, reduce cost of production, reasonable increase wall thickness, reduce reject rate, yield rate is by 40 ~ 50%, rise to 80 ~ 90%, improve the surface finishment of product simultaneously.
Increase external diameter and the wall thickness of product, keep the internal diameter of product constant, tilted tube 1 and vertical pipeline are in angle of 45 degrees simultaneously, increase circulation and the reversing force of product.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that embodiment of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
