Description
Technical Field
The utility model relates to the technical field of hardware casting, in particular to a sand shooting structure with good noise reduction performance and a core shooting machine.
Background
The core shooter is a device that uses compressed air to uniformly inject the molding sand into the flask for pre-compaction, and then applies pressure to compact the molding sand. The common injection molding machine has a vertical parting flaskless injection molding machine and a horizontal parting flaskless injection molding machine. The core shooter has the working principle that a core-sand mixture taking liquid or solid thermosetting resin as a binder is shot into a heated core box, a sand core is preheated in the core box and quickly hardened to a certain thickness, and then the sand core is taken out, so that a sand core finished product with a smooth surface and an accurate size is formed.
In the working process of the core shooting machine, a sand shooting valve is needed to control the gas storage bag to input high-pressure gas to the sand shooting head, and the high-pressure gas is used for pushing the sand core to be shot out of the sand shooting head to the core box.
In the structure, the sand shooting valve works discontinuously, so the sand shooting valve is generally provided with the exhaust valve at the top, and after the sand shooting valve stops single sand shooting, the exhaust valve is used for exhausting redundant high-pressure gas, but the high-pressure gas is easy to generate huge noise in the exhausting process, so that the noise pollution is caused to the working environment, and the health of operators is damaged.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides a sand shooting structure and a core shooting machine which are simple in design and good in noise reduction performance.
The utility model discloses a sand shooting structure with good noise reduction performance, which comprises: the air supply pipe is communicated with the air storage bag, the air storage bag is communicated with the sand shooting head through the sand shooting valve, the exhaust valve is connected with the top of the sand shooting valve, and the exhaust valve is connected with the air supply pipe through the sound guide pipe.
According to an embodiment of the present invention, the sound guide tube is of a bellows structure.
According to an embodiment of the present invention, a filter screen is further disposed between the sound guide tube and the exhaust valve.
According to one embodiment of the utility model, a transparent viewing window is embedded in the sand shooting head.
The utility model also discloses a core shooting machine which comprises the sand shooting structure.
The sand shooting structure of the utility model communicates the exhaust valve with the blast pipe through the sound guide pipe, and guides the noise generated when the exhaust valve works into the blast pipe through the sound guide pipe, so that the noise is transmitted and consumed in the blast pipe, thereby greatly reducing the noise pollution generated when the sand shooting structure works and improving the safety of the working environment.

Detailed Description
The sand shooting structure and the core shooting machine with good noise reduction performance of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
Please refer to fig. 1.
The utility model provides a sand shooting structure with good noise reduction performance, which mainly comprises an air supply pipe 1, a sand shooting head 2, an air storage bag 3, a sand shooting valve 4, an exhaust valve 5 and a sound guide pipe 6. The air supply pipe 1 is connected with an external high-pressure air source, the air supply pipe 1 is communicated with the air storage bag 3, a valve control high-pressure body is arranged at the joint of the air storage bag 3 and the air supply pipe 1 and is controlled to enter, the air storage bag 3 is communicated with the sand shooting head 2 through the sand shooting valve 4, the exhaust valve 5 is connected with the top of the sand shooting valve 4, and the top of the exhaust valve 5 is connected with the air supply pipe 1 through the sound guide pipe 6. The sound guide pipe 6 is of a bellows structure, so that the sound guide pipe 6 can buffer and absorb the impact generated when the exhaust valve 5 exhausts. Still be provided with filter screen 7 between leading note pipe 6 and discharge valve 5, further filter discharge valve 5 combustion gas through filter screen 7, prevent that the gas that discharge valve 5 discharged from mixing with the dust, cause the pollution to the high-pressure gas that blast pipe 4 carried, effectively guarantee to penetrate the stability of sand process. Penetrate and still inlay on the sand head 2 and be equipped with transparent observation window 8, in this application, penetrate 2 accessible autoloading structures of sand head and carry out the automatic molding sand of packing, for example spiral material loading pole etc. utilize transparent observation window 8 can the real-time observation penetrate the molding sand reserves in the sand head 2 to the operating personnel of being convenient for in time supply to the molding sand.
When the sand shooting structure is adopted for work, the blast pipe 1 is used for filling high-pressure gas into the gas storage bag 3, when sand shooting is conducted and modeling is conducted, the sand shooting valve 4 is conducted to input high-pressure gas to the sand shooting head 2, molding sand is shot into the core box from the sand shooting head 2 at high speed by utilizing the high-pressure gas, when the single sand shooting work is finished, the exhaust valve 5 works to exhaust, the exhausted gas and noise are input into the blast pipe 1 through the sound guide pipe 6, the noise is transmitted and consumed in the blast pipe 1, the noise generated by the work of equipment is greatly reduced, and the noise pollution to the work environment is reduced.
The utility model also provides a core shooting machine, which comprises the sand shooting structure, wherein the sound guide pipe 6 is used for guiding the noise generated by the operation of the exhaust valve 5 into the blast pipe 1, so that the noise generated during the operation of the core shooting machine is greatly reduced.
In summary, the sand shooting structure of the utility model communicates the exhaust valve with the blast pipe through the sound guide pipe, and noise generated when the exhaust valve works is guided into the blast pipe through the sound guide pipe, so that the noise is transmitted and consumed in the blast pipe, thereby greatly reducing noise pollution generated when the sand shooting structure works and improving the safety of the working environment.
In the description of the present invention, it is to be understood that terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, which indicate orientations or positional relationships, are used based on the orientations or positional relationships shown in the drawings only for the convenience of describing the present invention and for the simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.
