Evanescent mode sand box three-dimensional compaction table

Abstract

The invention relates to an evanescent mode sand box three-dimensional compaction table, belongs to the technical field of mechanical compaction, and solves the technical problems that a traditional sand box to be compacted is not firmly clamped during compaction, and the compaction effect is poor. According to the solution, the evanescent mode sand box three-dimensional compaction table comprises a base, a plurality of supporting columns, a plurality of air springs, a vibrating table, a plurality of vibrating motors, an air source and at least two clamping devices, wherein each clamping device comprises an air cylinder, an air cylinder fixing seat, a clamping block and a control system, and the air cylinders and the vibrating motors are electrically connected with the control systems respectively; and a first supporting table, a second supporting table and a third supporting table which are consistent in height are sequentially arranged in the middle of the top face of the vibrating table in the length direction, and a three-dimensional compaction table body is arranged below a sand box running track. The three-dimensional compaction table is simple in structure, stable and firm, the running noise is greatly lowered, the vibration source energy of the compaction table is fully utilized through the improvement in the clamping degree, optimal filling is achieved, and the compaction effect is better.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration, and in particular relates to a three-dimensional vibration table for a lost foam sand box. Background technique [0002] Lost Foam Casting is a new technology with nearly no margin and precise molding. After bonding and combining foam models similar in size and shape to castings to form a model cluster, then brush refractory paint on it and dry it, and then bury it in pearl sand. Or vibrating molding in dry quartz sand, then pouring to vaporize the model, then the liquid metal occupies the position of the model, and the liquid metal solidifies and cools to form a new casting method. When the foamed model is placed in the sand box to be vibrated, it must Pour pearl sand or dry quartz sand and vibrate. The pearl sand or dry quartz sand should be fully vibrated, so that pearl sand or dry quartz sand can fully surround the foaming model and fill the internal holes. [0003] The vibratin...
