Description
Technical field
The present invention relates to sand casting technical field, is a kind of pressure sand device of moulding machine specifically.
Background technology
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.The pressure sand device of this invention is that cantilever is arranged, the shortcoming that cantilever is arranged is to there will be after machine uses a period of time the phenomenon that cantilever becomes curved, cause the problem that pressure sand is uneven, although this invention is provided with location hook, but because strength during pressure sand is comparatively large, after work a period of time, still there will be the phenomenon that cantilever becomes curved.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of pressure sand device of moulding machine, the problem occurring owing to using for a long time pressing sand uneven can be solved, the generation of useless mould can be reduced.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pressure sand device of moulding machine, and comprise workbench, left column, right column and pressure sand device, described driving water placing flat, described left column and right column lay respectively at workbench both sides.
Described pressure sand device comprises transverse arm, pressing plate and four top-pressure gas pneumatic cylinders, and described transverse arm right-hand member is connected by bearing with right column, and transverse arm freely can rotate around right column, and transverse arm left end is provided with semicircular locating ring; Described transverse arm lower surface is welded with pressing plate, is also provided with reinforcement between pressing plate and transverse arm; Four described top-pressure gas pneumatic cylinders are arranged in four corners below workbench; Described pressure sand device is positioned at above workbench, and pressure sand device is connected by bearing with between right column.Transverse arm is forwarded to workbench, now transverse arm two ends in the vertical direction is fixed, then four top-pressure gas pneumatic cylinders are started, four top-pressure gas pneumatic cylinders are simultaneously by workbench jack-up, after the pressure of certain hour to be held, four top-pressure gas pneumatic cylinders decline simultaneously, and workbench is put back to original position, have now both completed the process of pressure sand.
Described left column is provided with the shaft part identical with the internal diameter of locating ring.
The air chamber of four described top-pressure gas pneumatic cylinders is connected, and the upper surface of four top-pressure gas pneumatic cylinders is provided with touch panel, and touch panel can increase the contact area of top-pressure gas pneumatic cylinder and workbench, makes workbench stressed more even.
The invention has the beneficial effects as follows: the pressure sand device of a kind of moulding machine of the present invention, the stressed mode in two ends is adopted to make transverse arm uniform stressed during described pressure sand device busy, prevent from using the transverse arm caused to bend for a long time and occur the phenomenon that pressure sand is uneven, reduce the generation of useless mould, improve generation efficiency, structure of the present invention is simple, reasonable in design, is easy to be extended and applied.
