Abstract
The utility model discloses a nozzle mechanism for a sand casting hot core box, which comprises a nozzle hollow shaft (1), a nozzle port (2) and a sand inlet (10). The nozzle port (2) is positioned at the lower end of the nozzle hollow shaft (1). The sand inlet (10) is arranged on the side wall of the upper part of the nozzle hollow shaft (1). The lower part of the sand inlet (10) and the periphery of the nozzle hollow shaft (1) are provided with sand retaining plates (15). The sand inlet is arranged on the side wall of the nozzle hollow shaft, casting sand enters the nozzle hollow shaft from the transverse direction and the flow velocity of the casting sand is relatively low, so that after adopting the structure of the utility model, the nozzle mechanism cannot cause airflow turbulence inside the nozzle hollow shaft, makes the casting sand distributed uniformly and has good sand shooting effect.
Description
Technical field:
The utility model relates to the casting mould field, is a kind of nozzle mechanism that is used for the sand casting hot box concretely.
Background technology:
In metal casting mould production process, need to adopt nozzle mechanism toward hot box injection sand, hot box comprises core box and following core box, be generally lower open die, penetrate the sand mouth at patrix, be provided with nozzle mechanism on the sand plate penetrating, will penetrate the sand plate when penetrating sand and move on to and penetrate Sha Kou, penetrate sand toward penetrating in the sand mouth by nozzle mechanism.The nozzle mechanism of prior art generally comprises nozzle hollow shaft, nozzle mouth, sand inlet, described nozzle mechanism is installed in penetrates on the sand plate, described nozzle mouth is positioned at the lower end of nozzle hollow shaft, described sand inlet is the opening of end face on the nozzle hollow shaft, molding sand vertically enters the nozzle hollow shaft from sand inlet, it is very fast that enter the molding sand flow velocity of nozzle hollow shaft this moment, causes the disorder of nozzle hollow shaft internal gas flow, molding sand skewness easily, and then it is bad to cause penetrating the sand effect.
The utility model content:
The technical problems to be solved in the utility model provides a kind of nozzle mechanism that is used for the sand casting hot box that can effectively slow down the molding sand flow velocity.
Technical solution of the present utility model is, the nozzle mechanism that is used for the sand casting hot box of following structure is provided, comprise nozzle hollow shaft, nozzle mouth, sand inlet, described nozzle mouth is positioned at the lower end of nozzle hollow shaft, and described sand inlet is located on the sidewall on nozzle hollow shaft top.
Adopt after the above structure compared with prior art, the utlity model has following advantage: adopt the utility model structure, because sand inlet is arranged on the sidewall of nozzle hollow shaft, molding sand is from laterally entering the nozzle hollow shaft, the flow velocity of molding sand is relatively low, thereby can not cause the disorder of nozzle hollow shaft internal gas flow, and it is comparatively even that molding sand is distributed, it is effective to penetrate sand.
As improvement, below sand inlet, the nozzle hollow shaft week upwards be provided with the sand block plate, like this, can prevent effectively that molding sand is from the sand inlet side leakage.
As improvement, in the nozzle hollow shaft, be provided with the molding sand buffer structure, described molding sand buffer structure is positioned at nozzle mouth top, the molding sand buffer structure comprises center trace, side direction buffering road, following center trace, molding sand cushions the road by side direction again through last center trace, come out to go forward side by side into the nozzle mouth from following center trace at last, the flow velocity of the molding sand of Jiang Diing has played the effect that cushions well greatly.
Description of drawings:
Accompanying drawing is the structural representation that is used for the nozzle mechanism of sand casting hot box of the present utility model.
Shown in the figure: 1, nozzle hollow shaft, 2, the nozzle mouth, 3, penetrate the sand plate, 4, nozzle pipe shaft, 5, first cavity, 6, second cavity, 7, advance cooling passage, 8, go out cooling passage, 9, sealing ring, 10, penetrate Sha Kou, 11, buffer structure, 12, go up center trace, 13, side direction buffering road, 14, following center trace, 15, the sand block plate.
The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The nozzle mechanism that is used for the sand casting hot box of the present utility model comprises nozzle hollow shaft 1, nozzle mouth 2, sand inlet 10, and described nozzle mouth 2 is positioned at the lower end of nozzle hollow shaft 1, and described sand inlet 10 is located on the sidewall on nozzle hollow shaft 1 top.
Below sand inlet 10, nozzle hollow shaft 1 week upwards be provided with sand block plate 15; At sand block plate 15 and penetrate between the sand plate 3 and be provided with pad.
Be provided with molding sand buffer structure 11 in nozzle hollow shaft 1, described molding sand buffer structure 11 is positioned at nozzle mouth 2 tops, and molding sand buffer structure 11 comprises center trace 12, side direction buffering road 13, following center trace 14.
Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.The utility model not only is confined to above embodiment, its concrete structure allows variation, as: described nozzle mechanism also can comprise nozzle pipe shaft 4, described nozzle pipe shaft 4 is connected nozzle hollow shaft 1 outside and penetrates sand plate 3 with upper/lower positions, the top of nozzle pipe shaft 4 is connected to be penetrated on the sand plate 3, be provided with first cavity 5 between sand plate 3 and the nozzle hollow shaft 1 penetrating, be provided with second cavity 6 between nozzle pipe shaft 4 and the nozzle hollow shaft 1, the described sand plate 3 of penetrating is provided with advancing cooling passage 7 and going out cooling passage 8 of communicating with first cavity 5, described first cavity 5 and second cavity 6 are to communicate, the molding sand of said structure in can the correlation nozzle mechanism cools off, and prevents that molding sand from solidifying and the obstruction that causes; Or the like.In a word, all various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
