Embodiment Construction
[0015] Such as figure 1 , figure 2 and image 3 Shown is the layered quicksand device for resin sand molding of the present invention, including a frame 1, four corners of the frame are provided with supporting legs, and the frame 1 is also fixedly provided with three boxes for storing surface sand, transition sand and back sand respectively. A sand bucket 2, the upper part of the sand bucket 2 is an open cylinder, the lower half of the sand bucket 2 is bucket-shaped, the lower mouth of the bucket is connected with a star-shaped feeder 7, and the lower end of the star-shaped feeder 7 is exported 7A is connected with a rotating mechanism 8 that can rotate 360°. The lower end of the rotating mechanism 8 is connected to the sand delivery hose 9 through a quick connector; the sand bucket 3 is hoisted above the sand bucket 2 by a suspension mechanism, and the upper part of the sand bucket 2 is fixed inside the cylinder. There is a bracket 2A for placing the sand bucket; the fram...

The invention relates to the technical field of casting and discloses a layered sand flowing device for phenolic sand molding. The layered sand flowing device for the phenolic sand molding comprises a framework, support legs are arranged at four corners of the framework, the framework is firmly provided with three sand hoppers respectively used for storing facing sand, transition sand and floor sand, the upper part of each sand hopper is open barrel-shaped, the lower half part of each sand hopper is hopper-shaped, the hopper-shaped lower hole is connected with a star-shaped discharger, the lower outlet of the star-shaped discharger is connected with a rotating mechanism capable of rotating by 360 degrees, and the lower end of the rotating mechanism is connected with a sand conveying hose through a quick coupling; a sand adding hopper is suspended above each sand hopper through a suspension mechanism, and a bracket convenient for holding the sand adding hopper is firmly arranged in the upper barrel of the corresponding sand hopper; a power distribution cabinet is arranged at the side of the framework, the power distribution cabinet is electrically connected with each star-shaped discharger, and a sand flowing control switch for controlling each star-shaped discharger switch is arranged on the panel of the power distribution cabinet.
Description
technical field [0001] The invention relates to the technical field of casting, in particular to a stratified quicksand device for resin sand molding. Background technique [0002] At present, the resin sand molding of domestic large-scale castings mainly uses a mobile sand mixer to flow a certain proportion of resin, silica sand, regenerated chrome ore and new chrome ore into the sand box in stages, and finally realize the back sand, transition Sand and surface sand three-layer sand modeling. There are following two deficiencies in quicksand by this method. One is that the mobile sand mixer can only flow one kind of resin sand at a time, and it is necessary to switch programs to realize the quicksand of three kinds of sand; on the other hand, the thickness of the sand layer after the sand flow through the mobile sand mixer cannot be effectively controlled, which is easy to cause sand The layers are mixed, compact and uneven. There is a big problem in the surface quality ...
