But in the process of consolidation, the switch of capping and the switch of invention need to control respectively, when needing to open capping, just necessary first valve-off, when needing to open valve, just first must close capping, operating procedure is more, reduces operating efficiency.
Summary of the invention
The invention is intended to provide a kind of increase work efficiency penetrate sand mold compacting device.
Sand mold compacting device is penetrated in this programme, comprise and press cylinder, capping is rotatably connected in consolidation cylinder, consolidation cylinder circumference is distributed with sand-spraying hole, consolidation cylinder is externally connected with the venting cavity of parcel sand-spraying hole, the side of consolidation cylinder is provided with air accumulator, air accumulator and venting cavity pass through pipeline communication, pipeline is provided with valve, the core box be communicated with consolidation cylinder is provided with below consolidation cylinder, the consolidation cylinder of consolidation cylinder and core box connectivity part has steam vent, capping is fixedly connected with rotating shaft, rotating shaft is fixedly connected with the first gear, first gears meshing has the second gear, second gear is fixedly connected on the valve rod of valve.
The know-why of this programme and beneficial effect are: first add molding sand to consolidation cylinder, rotating shaft, rotating shaft drives capping to rotate, the import of consolidation cylinder is opened by capping, molding sand will flow in consolidation cylinder, rotating shaft simultaneously also drives the first pinion rotation, first gear driven second pinion rotation, second gear driven valve rod rotates, valve is closed, when molding sand reaches a certain amount of, rotate capping again the import of consolidation cylinder is closed, while consolidation cylinder is closed in capping, valve is opened again, to enter in venting cavity by pipeline with the gas of certain pressure in air accumulator, enter in consolidation cylinder through venting cavity through sand-spraying hole, forming gas sand flow in consolidation cylinder injects in core box, air in die cavity in core box is discharged by steam vent, similar to the consolidation principle of ramming, the kinetic energy penetrating sand consolidation mainly sand air-flow becomes the consolidation merit of molding sand, main flow direction impacts molding sand, on non-mainstream, by steam vent inside and outside differential pressure, form the effect of filter stream consolidation.
Compared with prior art, this device only need control the first gear and just can complete, and capping is opened or closed, and opening or closing of interlocking valve, decrease operating procedure, improve operating efficiency.
Further, valve is gate valve, and gate valve is an opening and closing element flashboard, and the direction of motion and the flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete shut-down, facilitate the circulation of gas.
Further, gate valve by Flange joint on pipeline, flange, the again blue flange of call or bead.Flange is interconnective part between pipe and pipe, for the connection between pipe end, facilitates gate valve and is connected on pipeline, also facilitate replacing and the installation of gate valve.
Further, rotating shaft is connected with motor, starter motor, driven by motor axis of rotation, and rotating shaft drives the first gear and capping to rotate, and facilitates opening or closing of capping, also facilitates opening or closing of the first gear control valve door.
