The key link of sand casting is moulding, and the core of moulding machine is sand densifying mechanism.Squeeze moulding machine a kind ofly should have the low speed sand densifying mechanism of history decades in producing, and its sand densifying mechanism is comparatively simple, but the low and skewness of compacting gained sand mold compactability; Formed clamp plate compacting is conducive to the uniformity improving model top and surrounding sand mold compactability; But in a word, squeeze mo(u)lding gained sand mold compactability is lower, and particularly the sand mold die joint degree of packing is on the low side, and gained casting dimension accuracy is low, and surface quality is poor.
Clay-bonded sand metal casting is a kind of conventional of sand casting and the good a kind of formative method of cast member quality.Clay-bonded sand metal casting is shaping is one of main production process of automobile, hot-water heating and hardware blank, is widely used, and occupies critical role in machine building industry.Wherein the making of clay-bonded sand sand mold is one of key link in castings production technical process, the making quality of sand mold is directly connected to quality and the yield rate of foundry goods, to raising casting quality, reduce casting cost and play vital effect, developed countries is all kinds of high-end automatic molding machine for this formative technology have developed, this kind of machinery has that production efficiency is high, steady quality, energy-conserving and environment-protective advantage, but because of it, prices are rather stiff, maintenance difficulties is large, is difficult to promote the use of in common customer.
Most domestic foundry enterprise is still using technique jolt-squeeze machine simple, backward in technique or squeeze molding machine to carry out sand mold making, the sand-mould quality poor stability made, equipment running noises are high, labour intensity is large, production cost high efficiency is low, environmental pollution weight, domestic casting industry is badly in need of the mo(u)lding equipment that high-end automatic molding machine replaces existing backwardness.
Application number is: a Chinese patent of 201010614447.X discloses a kind of moulding machine, comprises body, is provided with the workbench of working plate, is provided with the rotating arm of pressing plate, shaking device, pressure sand device and die lifter; Described working plate is horizontally disposed with; Described body top is provided with a rotating shaft, and described rotating arm to be fixedly installed in this rotating shaft and can to rotate along with the rotation of this rotating shaft; Described workbench is positioned at body one side, and described rotating arm is with dynamic pressure plate to be located at directly over working plate in the process doing reciprocating rotation.This invention makes pressing plate can do with rotating arm to horizontally rotate, and when carrying out adding the operation such as sand, molding for sandbox, first rotating arm and press plate rotary certain angle, can make without hindrance thing above sandbox, so without the need to pressing plate is arranged on high height; When carrying out top pressure compacting operation, then pressing plate is gone to above workbench and sandbox.This invention adopts vibrations cylinder as vibroseis, and the noise produced in vibrations process is comparatively large, when this moulding machine of multiple stage works simultaneously, will cause very large noise pollution, and cause immeasurable injury to the healthy of workman.
For above problem, the invention provides a kind of shaking device of moulding machine, can shake by multiple degrees of freedom, shake uniform high-efficiency more, and the noise produced in the course of the work is less.
Summary of the invention
