The utility model relates to a kind of core shooter, and what be specifically related to a kind of core shooter penetrates sand exhaust gear.
Background technology
After sand penetrated by core shooter, must carry out penetrating sand exhaust event, to avoid, pressure in core is large affects core quality, and the nozzle that blasting unit pressure can be avoided to cause greatly leaks sand and sprays the appearance of grey phenomenon, generally for realization and penetrate sand exhaust, core shooter She Sha mechanism need be exhausted, see Fig. 1, as shown in legend wherein, penetrate sand exhaust gear and comprise sand-shooting head device and exhaust apparatus, sand-shooting head device comprises penetrates sand chamber 1, blasting unit 2 and sand-shooting head 3, exhaust apparatus comprises exhaust net 4, blast pipe 5, main exhaust valve 6, flexible pipe 7 and muffler 8, molding sand after penetrating sand in blasting unit 2 is launched in die cavity by sand-shooting head 3, main exhaust valve 6 is opened, residual gas in blasting unit 2 rises through exhaust net 4 and enters and penetrate sand chamber 12, and then rise through blast pipe 5 and main exhaust valve 6 and flexible pipe 7 and enter to penetrate sand muffler 8.
The defect of prior art has:
1, generally for the latus rectum (DN32 ~ DN 80) meeting Quick air-discharge air bleeding valve can be larger, when gases at high pressure (3bar ~ 5bar) a large amount of in blasting unit are discharged suddenly, noise is very large, and existing silencing means well cannot play the effect of noise reduction, noise reduction;
2, a large amount of in blasting unit gases at high pressure are discharged suddenly, and correlation sand exhaust net has very large impact, and can be online to penetrating sand exhaust by a part of abrasive band, and blocking exhaust net, the life-span of sand effect and exhaust net is penetrated in impact.
Summary of the invention
What goal of the invention of the present utility model was to provide a kind of core shooter penetrates sand exhaust gear, can reduce the noise produced when penetrating sand exhaust, avoids the appearance of penetrating sand exhaust net scab phenomenon, extends the exhaust net life-span.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of core shooter penetrate sand exhaust gear, comprise sand-shooting head device and exhaust apparatus, described sand-shooting head device is primarily of gas storage bag, air inlet pipe, intake valve, penetrate sand chamber and blasting unit formation, described exhaust apparatus is primarily of exhaust net, blast pipe, air bleeding valve and muffler are formed, described sand chamber of penetrating has air inlet port, air outlet and exhaust port, described air inlet port is communicated with described gas storage bag by described air inlet pipe, described air outlet described exhaust net is set and in working order time be communicated with described blasting unit, described exhaust port is communicated with described muffler by described blast pipe, described intake valve is arranged in described air inlet pipe, described air bleeding valve is arranged on described blast pipe, described air bleeding valve is set to the adjustable row air valve of adjustable row tolerance, or described air bleeding valve comprises walkthrough air valve in parallel and main exhaust valve, described walkthrough air valve is set to little latus rectum valve, described main exhaust valve is set to big orifice valve.
Further technical scheme, the latus rectum of described walkthrough air valve is DN6 ~ DN25.
Further technical scheme, the latus rectum of described main exhaust valve is DN32 ~ DN80.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the Combination application of adjustable row air valve or walkthrough air valve and main exhaust valve is adopted, and the mode that order is opened, realize the noise reduction of penetrating sand exhaust apparatus;
2, walkthrough air valve adopts little latus rectum valve, air bleeding valve adopts big orifice valve, adjustable row air valve is first adjusted to little capacity or walkthrough air valve is first opened, and gases at high pressure step-down is discharged, can not produce noise by the mode of low discharge, after pressure drops to certain numerical value, adjustable row air valve is opened after being first adjusted to large capacity or main exhaust valve, discharges, large discharge gas due to the effect without high pressure, also noise can not be produced, also can not be online to exhaust by abrasive band in blasting unit.
Accompanying drawing explanation
Fig. 1 is the structural representation penetrating sand exhaust gear of core shooter in prior art;
The structural representation penetrating sand exhaust gear of core shooter disclosed in Fig. 2 the utility model.
Wherein,
1, sand chamber is penetrated; 2, blasting unit; 3, sand-shooting head; 4, net is vented; 5, blast pipe; 6, main exhaust valve; 7, flexible pipe; 8, muffler; 9, walkthrough air valve.
