Abstract
The utility model discloses a coated sand tool for iron-mould coated sand casting, and particularly relates to an easily-cleaned sand shooting nozzle device which comprises a sand shooting nozzle and a sand shooting board, and is characterized in that the sand shooting nozzle is fixed on the sand shooting board, the position and the size of the diameter of the sand shooting nozzle are matched with those of sand shooting holes arranged on an iron mould, the length of the part of the sand shooting nozzle protruding the sand shooting board is matched with the depths of the sand shooting holes arranged in the iron mould, and the thicknesses of coated sand layers in all the sand shooting holes arranged in the iron mould are consistent. The sand shooting holes arranged in the iron mould in the production process of iron-mould coated sand casting are easily cleaned, and the easily-cleaned sand shooting nozzle device also has good pouring exhaust function in the pouring process of molten iron.
Description
Technical field
The utility model relates to the casting technique equipment, especially is applied to the Iron Mould Coated Sand casting with covering the sand frock.
Background technology
The Iron Mould Coated Sand casting belongs to one of Special Processes of Metal Castings, and its casting mold is on the metal mold inner chamber, to be covered with the skim precoated sand to form casting mold.The general mode of penetrating sand molding that adopts of casting mold is promptly injected gap swage and model between with precoated sand through the sand-spraying hole of swage with compressed air, forms and covers layer of sand.After the swage cast, must clean out the precoated sand that solidifies in the sand-spraying hole, that just can carry out next time covers the sand sand molding.The mode that several kinds of cleaning swage sand-spraying holes are generally arranged: adopt the pressure mandril apical pore, go out sand-spraying hole to the precoated sand capital that has certain intensity to solidify in the sand-spraying hole; Adopt electric drill that this part sand cylindrical drill is fallen.Owing to penetrate sand needs, the sand-spraying hole that has is very long, and the cleaning of these swage sand-spraying holes just is difficult to, and swage apical pore machine is stressed very inhomogeneous in the apical pore process, and is easy stuck or do not push up.The gas that very long sand-spraying hole is unfavorable for producing in the casting mold die cavity in the casting process is through the sand-spraying hole discharge.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and provide that a kind of the swage sand-spraying hole is easy to clear up, in molten steel pouring course, can also play good cast scavenging action in the Iron Mould Coated Sand foundry production penetrates the sand mouth device.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is easy to clear up penetrates the sand mouth device; Comprise and penetrate Sha Zui and penetrate the sand plate; It is characterized in that: the described Sha Zui of penetrating is fixed on and penetrates on the sand plate; Penetrate the sand-spraying hole coupling on Sha Zui position and diameter and the swage, penetrate the outstanding length of penetrating the sand plate of sand mouth and mate, cover the sand layer thickness unanimity in the swage in each sand-spraying hole with the degree of depth of the sand-spraying hole on the swage.
The described sand mouth outside diameter of penetrating of the utility model is than the little 2-5mm of sand-spraying hole diameter on the swage.
The described sand layer thickness that covers of the utility model is 20-30mm.
The utility model compared with prior art has following beneficial effect: in the utility model penetrate the outstanding length of penetrating the sand plate of sand mouth can be according to the degree of depth adjustment of sand-spraying hole on the swage; Thereby what make each sand-spraying hole consolidation in the swage covers the sand layer thickness unanimity; Sand-spraying hole apical pore machine apical pore power is little when swage is cleared up, and can not produce stuck phenomenon because of unbalance stress.The gas that produces in the die cavity when pouring into a mould in the production process can be discharged through sand-spraying hole, reduces the bleb defective.

Fig. 2 is the utility model molding status architecture sketch map.
The specific embodiment
Referring to Fig. 1～Fig. 2, the utility model comprises: penetrate sand plate 1, penetrate sand mouth 2.Penetrate sand mouth 2 materials and adopt the surface hardening of 45# steel, case hardness is high, can bear precoated sand and spray friction repeatedly.Penetrate sand mouth 2 and be fixed on and penetrate on the sand plate 1, penetrate sand-spraying hole 5 couplings on sand mouth 2 positions and the swage 3, penetrate sand mouth 2 outside diameters than the little 2-5mm of 5 diameters of the sand-spraying hole on the swage 3.Penetrate the outstanding length of penetrating sand plate 1 of sand mouth 2 and mate, cover layer of sand 4 consistency of thickness in the swage 3 in each sand-spraying hole 5, cover layer of sand 4 thickness at 20-30mm with the degree of depth of the sand-spraying hole 5 on the swage 3.
Operation principle: when the Iron Mould Coated Sand moulding, penetrate in the sand-spraying hole 5 that sand mouth 2 gos deep into swage 3, penetrate sand then, penetrate sand solidify accomplish after, penetrate sand plate 1 and break away from swage 3, the layer of sand 4 that covers in the swage 3 in each sand-spraying hole 5 all remains on same thickness.
Above content described in this specification only is to be illustrated what the utility model structure did.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
Claims (3)
- One kind be easy to clear up penetrate the sand mouth device; Comprise and penetrate Sha Zui and penetrate the sand plate; It is characterized in that: the described Sha Zui of penetrating is fixed on and penetrates on the sand plate; Penetrate the sand-spraying hole coupling on Sha Zui position and diameter and the swage, penetrate the outstanding length of penetrating the sand plate of sand mouth and mate, cover the sand layer thickness unanimity in the swage in each sand-spraying hole with the degree of depth of the sand-spraying hole on the swage.
- 2. according to claim 1 be easy to clear up penetrate the sand mouth device, it is characterized in that: the described sand mouth outside diameter of penetrating is than the little 2-5mm of sand-spraying hole diameter on the swage.
