Abstract
The utility model discloses a novel bleeded riser structure, comprising an upper die mold, wherein the upper part of the upper die mold is connected with a sand mold shell; a sand box is arranged above the sand mold shell; the upper part of the sand mold shell is connected with a vent hole seat which supports a blocking block; a concave cavity is formed in the middle of the blocking block; a steel riser is placed in the concave cavity, and two vent holes are formed in the steel riser. The novel bleeded riser structure has the beneficial effects that an exhausting system is additionally arranged to ensure that gases in a die cavity are discharged in time and the air hole defect rate is reduced; the steel riser has a cooling function to ensure that molten iron in the vent holes is solidified as soon as possible and the molten iron is saved; the steel riser can be repeatedly used and has a long service life; the realization of the exhausting system ensures that the operation is simple and convenient and the time and labor are saved; the steel riser is precise in size and good in surface quality, can be well matched with a sand mold in use, and is unlikely to cause other quality hidden troubles.
Description
Technical field
The utility model relates to a kind of exhaust system structure, relates in particular to a kind of novel riser runner structure.
Background technology
Axle housing production adopts device for sand coated iron mould technique, and in casting process, sand mold can discharge a large amount of gas in moment, if gas discharging not in time, the probability that foundry goods produces pore will increase greatly.If at the beginning of the axle housing casting Technology Design, do not offer exhaust passage, after small lot batch manufacture, find, cast(ing) surface produces the pore probability and has surpassed 80%, the foundry goods that will cause that gas hole defect is serious is scrapped, because causing the quantity that foundry goods is scrapped, gas hole defect accounts for 70% of total quantity scrapped, traditional method for exhausting is as air-out needle, exhaust rising head etc., all there are some wastes, complex operation, easily cause the problem of other defect, so solve the bleb defect in the urgent need to novel gas extraction system.
The utility model content
The deficiency existed for solving prior art, the utility model specifically discloses a kind of novel riser runner structure, and the utility model has increased gas extraction system, makes the gas in die cavity obtain timely discharge, has reduced the gas hole defect rate.
For achieving the above object, concrete scheme of the present utility model is as follows:
A kind of novel riser runner structure, comprise that patrix touches tool, and the top that patrix is touched tool is connected with the sand mold shell, the top of sand mold shell is provided with sandbox, and sand mold shell top is connected with the venthole seat, venthole seat supports sprue, in the middle of sprue, a cavity is arranged, the steel rising head is placed in cavity.
Be provided with a venthole in described steel rising head.
Make the venthole seat on upper die mold, during moulding, sprue is placed at the venthole place, and venthole seat supports sprue makes the sand mold of producing form cavity, before casting pouring, places the steel rising head at the cavity place and gets final product.
The beneficial effects of the utility model:
1, increase gas extraction system, made the gas in die cavity obtain timely discharge, reduced the gas hole defect rate;
2, the steel rising head has cooling effect, and the iron liquid of venthole is solidified as early as possible, has saved iron liquid;
3, the steel rising head is reusable, long service life;
4, the realization of gas extraction system, simple to operation, time saving and energy saving;
5, the steel Riser Dimensions is accurate, and surface quality is good, in use with sand mold, works good, and is difficult for causing other hidden danger of quality.
The accompanying drawing explanation
Structure chart during Fig. 1 moulding of the present utility model;
Structure chart during Fig. 2 cast of the present utility model;
The existing exhaust system structure figure of Fig. 3;
In figure, 1 upper die mold, 2 sand mold shells, 3 sandboxes, 4 venthole seats, 5 sprues, 6 steel rising heads, 7 ventholes.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 1, a kind of novel riser runner structure, comprise upper die mold 1, the top that patrix is touched tool 1 is connected with sand mold shell 2, and the top of sand mold shell 2 is provided with sandbox 3, upper die mold 1 is threaded with venthole seat 4, venthole seat 4 supports sprue 5, in the middle of sprue 5, a cavity is arranged, as shown in Figure 2, steel rising head 6 is placed in the cavity formed by sprue 5, is provided with a venthole 7 in described steel rising head.
Existing exhaust system structure figure as shown in Figure 3, does not have concrete exhaust measure.
On upper die mold, 1 makes air outlet base, and during moulding, sprue 5 is placed at venthole 7 places, and venthole seat 4 supports sprue 5, makes the sand mold of producing form cavity, before casting pouring, places steel rising head 6 at the cavity place and gets final product.
Claims (2)
1. a novel riser runner structure, it is characterized in that, comprise that patrix touches tool, the top that patrix is touched tool is connected with the sand mold shell, the top of sand mold shell is provided with sandbox, and upper die mold is connected with the venthole seat, venthole seat supports sprue, in the middle of sprue, a cavity is arranged, the steel rising head is placed in the cavity formed by sprue.
