Description
Technical field
The utility model relates to a kind of 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 penetrating in the sand plate of penetrating Sha Zui, swage with compressed air, forms and covers layer of sand.Because of precoated sand belongs to dry sand, mobile fine, spill in the mouth for preventing precoated sand sand of penetrating from penetrate the sand plate under the situation of not penetrating sand, penetrate the structure that the sand mouth generally adopts the physics stocking angle of penetrating in the sand plate.There are several deficiencies in this structure in actual production: when leaking gas in the blasting unit, there is certain air pressure in blasting unit, and precoated sand can flow out from penetrate the sand mouth automatically; Swage produces slight vibrations during matched moulds or around the moulding machine in moulding machine, the precoated sand of penetrating in the sand mouth is flowed out.The generation of above-mentioned several kinds of situation, the swage sand-spraying hole in all can handle modeling is blocked, thereby influence swage cover the sand molding quality.When covering sand molding in addition, swage and penetrate the disengaging between the sand plate must wait when the air pressure in the blasting unit is consistent with ambient atmosphere pressure fully in the moulding machine (the sand gas of penetrating in the blasting unit is emptied completely) just can carry out; Otherwise the sand of penetrating in the sand mouth will all spill; General evacuation time 30-50 does not wait second, thereby influences the production efficiency of moulding machine, swage with penetrate the overlong time that the sand plate contacts; Also make the precoated sand caking of penetrating in the sand plate easily, sand molding is covered in final influence.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and provide a kind of and can solve Iron Mould Coated Sand casting and cover and penetrate in the sand mold modeling process that the sand plate leaks the sand phenomenon, the Iron Mould Coated Sand that can improve the production efficiency of covering the sand molding machine is penetrated sand plate leakproof sand and penetrated Sha Zui.
The technical scheme that the utility model solves the problems of the technologies described above employing is: this Iron Mould Coated Sand is penetrated sand plate leakproof sand and is penetrated Sha Zui, is arranged on and penetrates on the sand plate, it is characterized in that: comprise and penetrate Sha Zui, spring, spring guide, spring bearer plate and fixed cover; Described spring bearer plate is fixed on the screw that is positioned at fixed cover through fixed cover and penetrates on the sand plate; Spring guide one end with penetrate the sand mouth and fix, the other end passes spring bearer plate and is slidingly matched with it, is set with spring on the spring guide; Spring one end contacts with spring bearer plate; The other end contacts with penetrating the sand mouth, penetrates Sha Zui and is slidingly arranged in and penetrates on the sand plate, penetrates and has logical sand hole on the sand mouth.
The utility model is described penetrates the sand mouth and the spring contact jaw is provided with spacing back-up ring, and logical sand hole is symmetrically distributed on the circumferencial direction of penetrating the sand mouth, logical sand hole to the distance of spacing back-up ring less than the thickness of penetrating the sand plate.
The described logical sand hole diameter of the utility model is 8-10mm.
The utility model compared with prior art has the following advantages: the utility model is penetrated the sand plate and is not had Lou sand phenomenon when not covering the sand molding operation, improves to cover the chiltern amount, stops to produce model cleaning work amount because of leaking sand.Exist at blasting unit under the prerequisite of air pressure, swage with penetrate the sand plate and can break away from, improved and covered the sand molding engine efficiency.Shorten the time of contact of penetrating sand plate and swage, made the precoated sand prevented from caking of penetrating in the sand plate, can not produce the phenomenon of sand-spraying hole being blocked because of the precoated sand caking aborning, helped covering the chiltern amount.
Description of drawings
Structural representation when Fig. 1 covers sand for the utility model.
Structural representation when Fig. 2 does not cover sand for the utility model.
The specific embodiment
Referring to Fig. 1 ~ Fig. 2, the utility model comprises to be penetrated sand mouth 1, spring 2, penetrates sand plate 3, spring guide 4, spring bearer plate 5, fixed cover 6, swage 7 and logical sand hole 8.Penetrate sand mouth 1 material and adopt the surface hardening of 45# steel, case hardness is high, can bear precoated sand and spray friction repeatedly.
Described spring bearer plate 5 is fixed on the screw 9 that is positioned at fixed cover 6 through fixed cover 6 and penetrates on the sand plate 3, and spring guide 4 one ends are fixed with penetrating sand mouth 1, and the other end passes spring bearer plate 5 and is slidingly matched with it.Be set with spring 2 on the spring guide 4, spring 2 one ends contact with spring bearer plate 5, and the other end contacts with penetrating sand mouth 1, and the thrust of spring 2 should be more than or equal to the summation that sand pressure adds friction of penetrating of covering sand molding.Penetrating sand mouth 1 is slidingly arranged in and penetrates on the sand plate 3; Penetrate sand mouth 1 and be provided with spacing back-up ring 11 with spring 2 contact jaws; Logical sand hole 8 is symmetrically distributed on the circumferencial direction of penetrating sand mouth 1, and less than the thickness of penetrating sand plate 3, the diameter that leads to sand hole 8 is 8-10mm to logical sand hole 8 to the distance of spacing back-up ring 11.
Operation principle: the Iron Mould Coated Sand moulding machine is when not moulding; Penetrate sand mouth 1 under the effect of spring 2 pressure; This is penetrated sand mouth 1 depress, cut off and penetrated sand plate 3 and penetrate the passage between the sand-spraying hole 8 in the sand mouth 1, the sand of penetrating in the sand plate 3 can not have air pressure because of the moulding machine blasting unit; Or shaken, the hourglass in the blasting unit is come out.When the Iron Mould Coated Sand moulding machine is prepared to cover sand molding; Swage 7 with penetrate sand plate 3 and contact sturdy; Swage 7 will be penetrated upwards jack-up of sand mouth 1, connect and will have penetrated sand plate 3 and penetrate the passage between the sand-spraying hole 8 in the sand mouth 1, when compressed air gets into blasting unit; Compressed air will be precoated sand through penetrating sand mouth 1, and sand molding is covered in the gap of injecting between swage 7 and the model.Penetrating sand accomplishes; When swage 7 descends, penetrate sand mouth 1 under the effect of spring 2 pressure, and then swage 7 descends synchronously; Because spring pressure is more than or equal to the summation that sand pressure adds friction of penetrating of covering sand molding; Penetrate sand mouth 1 and contact with swage 7 all the time, be forced into fully and penetrate on the sand plate 3, penetrate sand mouth 1 and be completely severed with the sand passage of penetrating of penetrating sand plate 3 until penetrating sand mouth 1.In this process and since swage 7 with penetrate that sand mouth 1 is tight fully and contact, so precoated sand can not spill from penetrate sand mouth 1.So accomplish in case penetrate sand, swage 7 just can descend, and needn't wait the blasting unit exhaust to finish to descend swage again, the sand molding time of covering that shortens greatly.
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.
