Multidimensional jolting platform of lost foam

Abstract

The invention relates to a multidimensional jolting platform of lost foam, which comprises an engine base. A jolting platform stander is arranged above the engine base, a plurality of air springs are arranged between the engine base and the jolting platform stander, a sand box is arranged at the upper part of the jolting platform stander, an electric motor seat is arranged at the front side of the engine base, the jolting platform stander is fixed with the sand box by a plurality of sets of clamping devices symmetrically arranged on two side parts of the stander, the jolting platform stander is internally provided with a first transmission shaft and a second transmission shaft which are in parallel with each other, and synchronous belt wheels and eccentric devices are arranged at the front ends and the rear ends of the first transmission shaft and the second transmission shaft. Compared with the prior art, directional filling is changed to be space vortex swinging multidirectional filling by the means that the eccentric devices are arranged at two ends of each transmission shaft, and transverse filling and even climbing filling with the optimal directional capability can be realized due to the three-dimensional vortex type vibration with continuous changing directions at any time, so that the multidimensional jolting platform has a good filling effect.

Description

technical field [0001] The invention relates to the technical field of vibrating devices, in particular to a multi-dimensional vibrating table for lost modes. Background technique [0002] The vibrating table is one of the key technologies of lost foam casting. It not only needs to compact the dry sand, but also needs to fill every corner of the cavity of the complex casting and compact it. The main direction of filling the dry sand of different castings is inconsistent. , Some also need to be filled in several directions, the vibration acceleration increases, the filling and compaction capabilities will increase, but the possibility of deformation of the foam mold is increased, the vibration acceleration is reduced, and the filling requirements cannot be met. Contents of the invention [0003] In order to solve the above problems, the present invention provides a vibrating mechanism that can be selectively used according to the main and secondary filling directions requir...
