Abstract
The utility model provides a structure of a sand spraying head of an automobile cylinder cover waterway core making machine, which comprises a machine body and a sand spraying head connected with a sand outlet of the machine body, wherein a threaded connection part is arranged at the upper end of the sand spraying head, and the threaded connection part adopts a coarse thread structure. After the threaded connection part of the sand spraying head is changed into the coarse thread structure, the coarse thread of the threaded connection part can be effectively prevented from being damaged by sand power during operation, therefore, the structure has the advantages that the connection is stable, the work is safe and reliable, and the like.
Description
Technical field:
The utility model relates to the core making machine field, particularly a kind of sand-shooting head structure of automobile cylinder cap water channel core making machine.
Background technology:
At present; the sand-shooting head of automobile cylinder cap water channel core making machine; it is the sand export that is mounted on core making machine by fine thread; because this fine thread connecting portion might enter the sand powder during work; and cause fine thread impaired; and then make the connecting portion of sand-shooting head loosening or obscission occur, owing to use different moulds can change sand-shooting head, often having the sand-shooting head damage needs to change.Influence ordinary production work.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and is connected firmly, the sand-shooting head structure of safe and reliable automobile cylinder cap water channel core making machine.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of sand-shooting head structure of automobile cylinder cap water channel core making machine comprises body and the sand-shooting head that is connected the body sand export, and the upper end of described sand-shooting head is provided with threaded joints, and described threaded joints adopts the coarse thread structure.
The pitch of described coarse thread is 3～5mm.
Also be provided with hex nut portion on the described sand-shooting head, described hex nut portion is close to the threaded joints setting.
Described sand-shooting head integral body is hollow rotary body shape.
The diameter of described threaded joints is less than the diameter of described other parts of sand-shooting head.
The utility model has following advantage with respect to prior art:
The utility model makes the threaded joints of sand-shooting head into the coarse thread structure, and the sand powder improves itself and the steadiness that the body sand export is connected to the damage of this threaded joints thread in the time of can effectively avoiding work, guarantees the reliability of work.In addition, also be provided with the hex nut portion of Gong screwing on the sand-shooting head of the present utility model, therefore easy for installation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the sand-shooting head structure of the automobile cylinder cap water channel core making machine that provides according to the utility model, comprise body 1 and the sand-shooting head 3 that is connected body sand export 2, the upper end of sand-shooting head 3 is provided with threaded joints 31, threaded joints 31 adopts the coarse thread structure, the pitch of coarse thread is 3～5mm, and preferred value is 4mm.
Also be provided with hex nut portion 32 on the described sand-shooting head 3, hex nut portion 32 is close to threaded joints 31 and is provided with, and when sand-shooting head 3 is installed, only need screw this hex nut portion 32, and is therefore very convenient.
Described sand-shooting head 3 integral body are hollow rotary body shape, and the diameter of threaded joints 31 is less than the diameter of sand-shooting head 3 other parts.
