Abstract

The utility model discloses a gating system with a sluice gate and a cross gate, and belongs to the gating system. According to an existing gating system, cost is high when a dross filter is adopted in the process of filtering residues. Blending gridding wires are easily produced on a casting. The gating system with the sluice gate and the cross gate comprises an outer pouring gate, a sprue, the cross gate and an inner sprue, wherein the outer pouring gate, the sprue, the cross gate and the inner sprue are communicated in sequence. The gating system with the sluice gate and the cross gate is characterized in that the sluice gate is arranged on the top of the cross gate. A slag retention space is formed in the front side of the sluice gate. The cross gate with a contractible cross section is formed on the lower side of the sluice gate. The cross gate can be directly manufactured on a cross gate wood pattern. In the process of molding and placing sand, the cross gate can be formed with a casting mold together. The cost of purchasing filter residues can be saved, and therefore the economic benefit is obvious. The working procedures and operations such as molding and sand placing are very convenient, unlike the trouble of placing filter residues. The gating system with the sluice gate and the cross gate is beneficial for popularization and application. As long as process design personnel control the height and gap (when two or over two are adopted) according to the demand, good effects of pushing off the slag can be achieved.

Description

Running gate system with the gate cross gate

Technical field

The utility model belongs to running gate system, and a kind of running gate system with the gate cross gate specifically guarantees to flow into the degree of purity of the iron liquid of die cavity to stopping of slag by gate.

Background technology

General running gate system is made of the pouring basin, sprue, cross gate, the ingate that are communicated with successively, and iron liquid is poured into from pouring basin, flows into casting mold (die cavity) by sprue, cross gate, ingate and solidifies rear formation foundry goods.Obtain high-quality foundry goods, necessarily require cross gate to have powerful pushing off the slag effect, make high pure iron liquid flow into casting mold, can prevent that foundry goods from causing useless because producing the casting flaws such as cinder hole, slag inclusion.Thereby the casting quality that guarantees has reduced percent defective, has improved economic benefit, now has been successfully applied on the large-scale wind electricity foundry goods more than 10 tons, and effect is fairly obvious.

The foundry goods that technical quality is had relatively high expectations does not especially allow the foundry goods of repair welding reuse such as wind-powered electricity generation class, oil cylinder class, compressor casing class etc. to casting flaw.Common pushing off the slag measure is more common in and establishes skim strainer in cross gate, strainer core carries out filter residue and obtains pure iron liquid, but every of the price of strainer core needs 30-50 unit, every of import strainer core then needs 120-180 unit, and expense is higher, has increased the production cost of foundry goods.

On the other hand, if when adopting the strainer core filter residue, 1340 ℃ iron liquid easily thrusts the grid wire in the strainer core is softening by strainer core, and the softening grid wire that thrusts can flow into casting mold with iron liquid, foundry goods is produced be mingled with grid wire and cause useless.

The utility model content

The technical assignment of the technical problems to be solved in the utility model and proposition is high, the easy defectives such as being mingled with grid wire that produces of foundry goods of cost when overcoming existing running gate system employing strainer core filter residue, and a kind of running gate system with the gate cross gate is provided.

For achieving the above object, running gate system with the gate cross gate of the present utility model comprises pouring basin, sprue, cross gate, the ingate that is communicated with successively, it is characterized in that: the top of described cross gate is provided with gate, the front side of described gate forms slag and keeps somewhere the space, the long-pending cross gate that dwindles of the downside Formation cross-section of described gate.

As the optimization technique means: described gate is a plurality of and distributes along the bearing of trend of described cross gate.Described gate is to the ridge shape body of downward-extension from the top of described cross gate.

The beneficial effects of the utility model are:

1. gate can directly be made at the cross gate wooden model, forms with casting mold to get final product when sand is put in moulding, can save the expense of buying strainer core, so economic benefit is obvious;

2. gate can directly be made at the cross gate wooden model, it is all very convenient that the process operations such as sand are put in moulding, unlike placing strainer core, bother, the height of regulating gate and spacing when above (two and two) be beneficial to and apply, as long as can reach preferably pushing off the slag effect to the technological design personnel according to demand.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to view;

The number in the figure explanation: the 1-pouring basin, the 2-sprue, the 3-cross gate, the 4-ingate, the 5-gate, the 6-slag is kept somewhere space, the cross gate of 7-reduced cross-sectional area.

The specific embodiment

Below in conjunction with Figure of description the utility model is described further.

Running gate system with the gate cross gate of the present utility model, as shown in Figure 1, 2, it comprises pouring basin 1, sprue 2, cross gate 3, the ingate 4 that is communicated with successively, the top of cross gate 3 is provided with gate 5, the front side of gate 5 forms slag and keeps somewhere space 6, the long-pending cross gate 7 that dwindles of the downside Formation cross-section of gate 5.Further, gate 5 is a plurality of and distributes along the bearing of trend of cross gate.Gate 5 is to the ridge shape body of downward-extension from the top of cross gate.

Gate 5 of the present utility model can directly be made at the cross gate wooden model, when sand is put in moulding, form with casting mold and get final product, can save the expense of buying strainer core, economic benefit is obviously (to produce one heavily about 12 tons wind power hub foundry goods as example, need 10-12 sheet strainer core during with strainer core (foamed ceramics type) filter residue, the utility model adopts does not then need strainer core with the gate cross gate, greatly reduces production costs); Simultaneously, it is all very convenient to make again moulding put the process operations such as sand, the height of regulating gate and spacing when above (two and two) unlike placing strainer core, bother, be beneficial to and apply, as long as can reach preferably pushing off the slag effect to the technological design personnel according to demand.

In casting process, when flowing through cross gate 3 with the iron liquid of slag (direction of arrow represents the flow direction of iron liquid among the figure), the slag in the iron liquid slowly floats because of light specific gravity, then firmly is trapped in slag by lock 5 door shields and keeps somewhere space 6.If the slag in the iron liquid is more, then can increase by the length that prolongs cross gate the quantity of gate, slag in the iron liquid stops through a lot of, make at last the higher iron liquid of degree of purity flow into die cavity, thereby obtain qualified foundry goods, eliminated foundry goods and caused useless owing to casting flaws such as producing slag inclusion, cinder hole.
