But in the process of consolidation, the switch of capping and the switch of valve 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.
Utility model content
The utility model is intended to provide a kind of molding sand consolidation She Sha mechanism increased work efficiency.
Molding sand consolidation She Sha mechanism in this programme, comprise 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 slidably connected in consolidation cylinder, capping is connected with cylinder, capping is hinged with connecting rod, connecting rod is hinged with rotating disk away from one end of capping, rotating disk 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, slip capping, the import of consolidation cylinder is opened by capping, molding sand will flow in consolidation cylinder, capping simultaneously also drivening rod swings, connecting rod drives dial rotation, driven by rotary disc valve rod rotates, valve is closed, when molding sand reaches a certain amount of, to slide again capping, the import of consolidation cylinder is closed by capping, 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, the slip that this device only need control capping just can complete operation, and capping is opened or closed, and opening or closing of linkage valve, decreases 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, capping is connected with cylinder, starts cylinder, cylinder drives capping to slide, and capping drives connecting rod swing, and connecting rod drives dial rotation, facilitates opening or closing of capping, also facilitates opening or closing of rotating disk by-pass valve control.
Further, be provided with the workbench supporting core box below core box, workbench can support core box, in the process of penetrating sand, ensures that core box is stablized.
