Abstract

The invention provides a casting method for an extension tabletop of a vibration instrument. The method comprises following steps: step 1: arranging a gating system which comprises a sprue, a cross gate and an ingate; step 2: performing a modeling process, wherein the binning modeling is used as the modeling manner, and the clay core splicing method is used for modeling; step 3: arranging chilling blocks: arranging chilling blocks at molding positions of parts with larger width and height in the extension tabletop of the vibration instrument; and step 4: arranging dead heads: arranging the dead heads at molding positions of hole parts in the extension tabletop of the vibration instrument. The casting method realizing casting of the extension tabletop of the vibration instrument with large-sized and special structures, and has beneficial effects that castings have no cracks or shrinkage hole defects, excellent quality and the like.

Description

technical field [0001] The invention relates to a casting forming method of an alloy workpiece, in particular to a method for casting an extended table top of a vibrating instrument, in particular to a casting process method for an extended table top of an electric vibration table.
