Abstract
The invention relates to a compacting mechanism and discloses a vacuum compacting mechanism. The vacuum compacting mechanism comprises a compacting cylinder, wherein a compacting plate capable of sliding up and down is connected in the compacting cylinder; through holes are formed in the bottom of the compacting cylinder; a vacuum tank is arranged at one side of the compacting cylinder and communicates with the through holes via a pipeline; the compacting plate is connected with a pull rod; the pull rod sleeves a driving rod capable of sliding up and down in the pull rod; the upper end of the driving rod is connected with a hydraulic cylinder; one side of the compacting cylinder is communicated with a feeding hopper. Compared with the prior art, the whole compacting process can be completed by an operator by just controlling the height of the compacting plate through the hydraulic cylinder without need of sliding the feeding hopper forth and back as well as opening and closing a sealing cover; the operation steps are reduced; the working efficiency is improved; due to three-step compacting operations of pre-compacting, compacting pressure of compressed air and further compacting through the hydraulic cylinder, the compacting effect is more significant.
Description
Technical field
The present invention relates to a kind of vacuum consolidation mechanism.
Background technology
The mechanization of moulding and coremaking is the core that Foundry Production simplifies.It directly reflects the level of production of foundry.The character of molding sand or core sand is depended in the technical process of moulding and coremaking and mechanization thereof, the process of moulding and coremaking, and equipment etc. used, for widely used clay-bonded sand, normal employing " flask molding ", the technical process of moulding comprises the operation such as transport of filling, consolidation, molding, lower core, mould assembling and sand mold and sandbox.The type of mo(u)lding equipment is different, and its method of operating is also different, but the most basic operation all comprises filling, consolidation and molding, wherein important with consolidation.
In recent years, mo(u)lding equipment has a great development, the jolt squeezing machine generally used in the past, by Slight Shock Squeeze is replaced, there have been developed multiple contact high pressure shockless jolt molding machine, without case and drawing shoot squeeze molding machine.The particularly air impulse molding machine of development in recent years, makes moulding mechanization enter the new stage of high-quality, efficient and low consumption.
Existing air impulse molding machine is generally divided into vacuum consolidation mechanism, impeller ramming mechanism and She Sha consolidation mechanism etc., wherein vacuum consolidation mechanism comprises and presses cylinder, press in cylinder be provided with can upper and lowerly be slidably connected press plate, pressing plate and being detachably connected on by pin presses in cylinder, presses on plate and has opening, and the opening pressing plate slidably connects capping, press above cylinder and slidably connect feed hopper, press bottom cylinder and have through hole, also comprise vacuum tank, vacuum tank is communicated with through hole, in the operating process of this device, first need to feed in raw material, first feed hopper is slided into side, operating personnel slide capping again, opening is opened, feed hopper being reset to presses on cylinder again, molding sand material is added in feed hopper, when molding sand is added to the amount of needs, again feed hopper is slided into side, the capping of pressing on plate is closed, pulling up pin, press plate and will be slided into the position with molding sand material joint by self gravitation, start vacuum tank, vacuum tank siphons away the air pressed in cylinder, make to press in cylinder and form vacuum, atmospheric pressure will apply pressure to pressing plate, press plate and consolidation will be carried out to molding sand downwards.
But in the process of charging, need the feed hopper that slidably reciprocates, add operating procedure, reduce operating efficiency; And this device also can only carry out a consolidation with atmospheric pressure to molding sand, compacting effect is general.
Summary of the invention
The invention is intended to provide a kind of and increase work efficiency, strengthen the vacuum consolidation mechanism of compacting effect.
Vacuum consolidation mechanism in this programme, comprise and press cylinder, press in cylinder be provided with can upper and lowerly be slidably connected press plate, press bottom cylinder and have through hole, press a side and be provided with vacuum tank, vacuum tank and through hole pass through pipeline communication, press on plate and be connected with pull bar, be socketed with the drive rod of upper and lower slip in pull bar in pull bar, drive rod upper end is connected with hydraulic cylinder, and the side of pressing cylinder is communicated with feed hopper.
The know-why of this programme and beneficial effect are: primer fluid cylinder pressure, hydraulic cylinder pulls drive rod to move upward, drive rod is upward sliding in pull bar, inveterate drive rod is socketed in pull bar, when drive rod slides into the top of pull bar, drive rod will pull pull bar to move upward, pull bar will pull and press plate and move upward, when the height pressing plate exceedes feed hopper, feed hopper is fed in raw material, molding sand presses in cylinder by entering into press below plate, when molding sand reaches enough amounts, restart hydraulic cylinder, drive rod is moved downward, drive rod moves downward in pull bar, pull bar due to gravity along with drive rod moves together, when pressing plate and contacting with molding sand, press plate and be in feed hopper and the below of pressing cylinder and be communicated with position, drive rod continues motion, and make drive rod slide into the bottom of pull bar, and drive pull bar to carry out pretension to molding sand downwards.
Start vacuum tank, vacuum tank siphons away the air pressed in cylinder, and make to press plate and become vacuum with the space of pressing cylinder formation, air applies downward pressure by pressing plate, press plate to move downward and carry out consolidation to molding sand further, then at primer fluid cylinder pressure, hydraulic cylinder drives drive rod to move downward again, and applies pressure to pull bar, pull bar will apply pressure to pressing plate, press plate and further consolidation is carried out to molding sand again, thus make molding sand can reach the better degree of packing, enhance compacting effect.
Compared with prior art, operating personnel only need by hydraulic cylinder, and the height controlling to press plate just can complete the process of whole compression, does not need the feed hopper that slidably reciprocates again, and goes switch capping, decrease operating procedure, improve operating efficiency.
Further, pipeline is provided with valve, controls vacuum tank and press being communicated with of cylinder by the switch of by-pass valve control, facilitates the vacuum tank of vacuum tank and presses the circulation of the gas in cylinder.
Further, feed hopper with press the position that cylinder is connected and be provided with capping, the setting of capping, even if the amount of the molding sand added is too many, make to press plate be still in higher than above feed hopper time, close capping, make to press cylinder with feed hopper separates, press plate and press cylinder formation space and still close, therefore when adding molding sand, will not take out in the urgent pressure cylinder of molding sand, reduce operating procedure, improve operating efficiency.
Further, press below cylinder and be communicated with die cavity seat, the die cavity in die cavity seat, the molding sand after consolidation can be made can to make different shapes as required.
Further, through hole circumference is distributed on the bottom of pressing cylinder, equally distributed through hole, can make to press the speed that the air everywhere in cylinder is sucked away consistent, make the pressure that is subject to above molding sand consistent everywhere, ensure that maintenance level above molding sand, make the shape compound standard more of molding sand.
