Abstract

The utility model discloses a vacuum sealed molding sand-tapping device, which includes a seat, a vibration table positioned above the seat, several air springs are equipped between the seat and the vibration table, vibration motors used to drive the vibration table to vibrate forward and backward are installed symmetrically at the left and right sides of the vibration table, and a vibration motor used to drive the vibration table to vibrate upward and downward are installed at the bottom side of the vibration table. Apply the air spring structure to lift and support the sand box, and make the vibration motors in X, Y and Z directions to start one by one or start at the same time to generate the one-dimensional, two-dimensional, three-dimensional vibration or vibration with arbitrary combination required so as to reach the most compact effect, fulfill all kinds of castings' molding requirements with different vibration forms and exciting force, avoid effectively badly filling of sand and improve the efficiency of filling compactly.

Description

Vacuum sealed molding molding sand jolt ramming device

Technical field

The utility model relates to a kind of vibrating device, relates in particular to a kind of vibrating device that is used for vacuum sealed molding.

Background technology

Vacuum sealed molding is a kind of physics molding, and it utilizes plastic sheeting sealing sandbox, and relies on air in the vavuum pump extraction type, pressure differential is arranged inside and outside causing casting mold, makes the dry sand consolidation, to form the physics formative method of required die cavity.

The packing density of molding sand has a significant impact foundry goods, for compression strength and the hardness that improves molding sand, must improve packing density, need be vibrated when back-up sand for this reason.Vibration also helps because of natural stocking angle influence in addition, the not filling of more readily accessible local locations when back-up sand, put up a bridge or gauffer during when film is local perpendicular to the back-up sand direction, also can influence sand thereunder fills up, after the decompression moulding, the bilayer film of this flatung just can draw back to its packless direction, makes mo(U)ld face form open state.The danger that also can cause foundry goods to increase wall thickness because of buckle when the degree of packing is not enough also can increase the fash of die joint.So carry out necessary vibration during back-up sand, it is very important making mobile original big dry sand obtain enough degree of packing, and the major parameter that influences the degree of packing is the size and Orientation of exciting force, put up a bridge or fold place at part horizontal convex-concave position with perpendicular to the film of back-up sand direction is local, only depend on the unidirectional exciting force of vertical direction often can not satisfy the requirement of the partial stowage and the degree of packing.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of to molding sand apply three-dimensional vibrating, make it be random Three-dimensional Flow, vacuum sealed molding of realizing best filling and compacting effect, raising filling and consolidation efficient is with molding sand jolt ramming device.

For achieving the above object, the technical solution of the utility model is: vacuum sealed molding molding sand jolt ramming device, comprise support, be positioned at the vibration table of support top, be provided with some air springs between described support and the vibration table, the left and right side of described vibration table is symmetrically installed with the vibrating motor that drives the vibration table side-to-side vibrations, the front and back sides of described vibration table is symmetrically installed with the vibrating motor that drives the vibration table porpoise, and the bottom surface of described vibration table is equipped with the vibrating motor that drives the vibration table up-down vibration.

Owing to adopt technique scheme, the utility model adopts lifting of air spring structure and supporting sandbox, utilize the vibrating motor of X, Y, Z direction successively or simultaneously to start, produce required one dimension, two dimension, three-dimensional or the vibration of combination arbitrarily, reach best compacting effect, satisfy the modeling requirement of different vibration mode of various foundry goods and exciting force, can avoid sand to fill bad and raising filling consolidation efficient effectively; The utility model is simple in structure, and operating maintenance is convenient, the complete repeatability of modeling process in guaranteeing to produce in batches.
