Abstract
The utility model discloses a flange casting system, comprising a straight casting sprue (1), further comprising a cross casting sprue (2), a vertical casting sprue (3), a disk-surface casting sprue (4) and an inlet casting sprue (5), wherein the lower end of the straight casting sprue (1) is communicated with one end of the cross casting sprue (2), the other end of the cross casting sprue (2) is communicated with the lower end of the vertical casting sprue (3), the upper end of the vertical casting sprue (3) is communicated with the middle part of the disk-surface casting sprue (4), the end of the disk-surface casting sprue (4) is communicated with the lower end of the inlet casting sprue (5), and the upper end of the inlet casting sprue (5) is communicated with a mould cavity (8). With the adoption of the flange casting system, the quality of the flanges is enhanced.
Description
Technical field
The utility model relates to the casting processing technical field, specifically relates to a kind of running gate system of ring flange.
Background technology
A kind of ring flange, through hole is established in the centre, and left and right sides wall thickness is thicker, the profile rounding off.Existing running gate system adopts bottom filling, and sprue is located in the inner chamber, and said inner chamber is meant the position of the filling molding sand that is surrounded by die cavity; Ingate is opened in the loam core of inner chamber; In order to accelerate the cooling velocity of potting syrup, in the thicker corresponding position of wall thickness chill is set, because potting syrup had successively from the time that sprue flows to each position of ring flange at die cavity wall thickness thicker part; Each position cooling velocity of ring flange is different when causing cast; Ring flange fluff and loose pore that cast is come out are more, and when adopting ultrasonic inspection to detect, the ring flange quality can not reach the quality requirement that needs.
The running gate system of prior art ring flange is watered the foundry goods that outpours: 1 ', sprue, 9 ', passage, 10 ', ring flange, 11 ', ingate, 12 ', chill.
The utility model content
The technical problem that the utility model will solve is that a kind of running gate system that can improve the ring flange of cast ring flange quality is provided.
The technical solution of the utility model is, a kind of running gate system with ring flange of following structure is provided, and comprises sprue; It also comprises cross gate, sprue, card running channel and inlet running channel; Said sprue lower end is communicated with cross gate one end, and the cross gate other end is communicated with the sprue lower end, and the sprue upper end is communicated with card running channel middle part; Card running channel end is communicated with inlet running channel lower end, and inlet running channel upper end is communicated with die cavity.
Said inlet running channel is a ring gate or along many evenly distributed running channels of card running channel circumferencial direction.
After adopting above structure, the running gate system of the utility model ring flange compared with prior art has the following advantages:
Because the running gate system of the utility model ring flange is provided with card running channel and inlet running channel; Described potting syrup gets into the card running channel and gets into die cavity via the inlet running channel behind sprue, cross gate, sprue; Because adopt card running channel and inlet running channel, the time difference that potting syrup gets into die cavity is little, cooling evenly; Reduce fluff and loose pore, can improve the ring flange quality of cast.
As a kind of improvement of the utility model, said inlet running channel is the outward-dipping oblique running channel in upper end, pours into a mould the running channel that retreads and removes from ring flange more easily.
Another kind as the utility model improves, and is provided with the steel pipe of pouring water of lower end closed in the molding sand that said die cavity surrounds.In the steel pipe of pouring water, inject cold water, potting syrup in the die cavity is played quick cooling, the cooling velocity of potting syrup is fast, the formation of loose hole and fluff when reducing cast; The steel pipe of pouring water in addition occupies greatly intracavity space, can reduce in the inner chamber raw-material uses such as molding sand, and the steel pipe of pouring water is recyclable to be utilized again, has reduced the cast cost.
As a kind of improvement of also having of the utility model, said sprue upper end is provided with enlarging, can accelerate the velocity of liquid assets of potting syrup.

The running gate system of the utility model ring flange and water the foundry goods that outpours: 1, sprue, 2, cross gate, 3, sprue, 4, the card running channel, 5, the inlet running channel, 6, the steel pipe of pouring water, 7, molding sand, 8, die cavity, 9, passage, 10, ring flange.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, Fig. 2, shown in Figure 3; The running gate system of the utility model ring flange comprises sprue 1, and it also comprises cross gate 2, sprue 3, card running channel 4 and inlet running channel 5, and said sprue 1 lower end is communicated with cross gate 2 one ends; Cross gate 2 other ends are communicated with sprue 3 lower ends; Sprue 3 upper ends are communicated with card running channel 4 middle parts, and card running channel 4 ends are communicated with inlet running channel 5 lower ends, and inlet running channel 5 upper ends are communicated with die cavity 8.
Said inlet running channel 5 is a ring gate or along many evenly distributed running channels of card running channel 4 circumferencial directions.
Said inlet running channel 5 is the outward-dipping oblique running channel in upper end.
Be provided with the steel pipe 6 of pouring water of lower end closed in the molding sand 7 that said die cavity 8 surrounds.
Said sprue 3 upper ends are provided with enlarging 3.1.
Be provided with a plurality of passages 9 in the molding sand on the said die cavity 8.
Shown in Figure 4 is the running gate system of prior art ring flange; Sprue 1 ' be located in the inner chamber; Said inner chamber is meant the position of the filling molding sand that is surrounded by die cavity, and ingate 11 ' open in the loam core of inner chamber is in order to accelerate the cooling velocity of potting syrup at die cavity wall thickness thicker part; Be provided with in the thicker corresponding position of wall thickness chill 12 ', be provided with in the molding sand on die cavity top passage 9 '.
