Abstract
The utility model discloses a moulding machine utilizing air impact, which is mainly characterized in that at the same time when a molding sand is compacted by the air impact, a squeezer plate linked to the utility model compacts the molding sand quickly. The utility model has the advantages that no quick sand is left on the back side of the sand mold, the molding is performed through one action, and the requirement of the molding sand is not too high. The water content of the molding sand is 6 percent to 7 percent, the air permeability is 67, the mold hardness can reach 83 (A-type durometer) when the intensity is 0.08KG /CM (2), and the original compressed air source in a shop floor can be used. The utility model is suitable for the mass production of medium-small products.
Description
The utility model is that a kind of gas that utilizes impacts molding sand, and the casting sand type mo(u)lding equipment of the system for compacting squeeze board compacting sand mold that links with it when gas impacts.
Existing sand mold mo(u)lding equipment adopts usually and shakes pressure type or penetrate two kinds of forms of squash type, and it is big that these two kinds of mo(u)lding equipments exist operating noise respectively, the labor strength height, difficult assurance of sand-mould quality and equipment investment are big, and the plant maintenance amount is big, disadvantage and weakness such as specification requirement height.For a change this situation, Japanese Xin Dong companies in 1980 at first delivered the experimental result (being called the static pressure moulding) of simple gas Impact Molding on the phase at " Jact News " NO.270, Jinan Casting And Forging Machinery Research Institute of the former First Machinery Industry Department of China has also carried out the feasibility test of similar gas Impact Molding method in 1980.China's first phase in 1984 " foundry machinery " magazine has also been introduced the research overview of the recent gas impact molding machine of West Germany BMD company.The simple gas impact molding machine of this class exists the weakness that there is floating sand at the sand mold back side.
The purpose of this utility model is to design a kind ofly impacts molding sand and the mo(u)lding equipment of the system for compacting squeeze board decline compacting sand mold that links with it with gas when impacting.
Critical piece of the present utility model is one and impacts head.This impact head mainly comprises four parts: top air storage chamber (1), bottom air storage chamber (4) is opened screen mechanism, system for compacting soon.Wherein gas pressure is 4～6kg/cm in the air storage chamber
2, the warming-up exercise step of this gas impact molding machine is: fast opening mechanism is closed, and bottom air storage chamber air inlet promotes the system for compacting piston and rises the fumarole of closed upper portion air storage chamber, top air storage chamber air inlet.The moulding action step makes the gap sealing of impacting between head, sandbox, template for impacting the rising of a decline or template and sand mold mechanism, rise mechanism opening this moment soon, the Compressed Gas that makes the bottom air storage chamber fast through the squeeze board percussion of too fast start mechanism and system for compacting on molding sand, at this moment because the reduction of bottom air storage chamber compressed air pressure, forming pressure differential between the air storage chamber up and down, the piston that the higher Compressed Gas of the pressure of top air storage chamber promotes system for compacting acts on the molding sand with impact velocity with piston rod drive squeeze board, makes it compacting.Then fast opening mechanism is closed, and impacts head and sandbox and rises, and finishes the moulding action.
The utility model mainly is applicable to the production in enormous quantities of medium and small foundry goods, overcome the existing disadvantage of the present moulding machine of China, molding sand consolidation principle of the present utility model is: the shock wave work done consolidation molding sand that pressed gas expansion at a high speed produces isolates molding sand sand group simultaneously, at this moment with the system for compacting squeeze board of fast opening mechanism interlock rapidly with the molding sand compacting, make molding sand finally have the higher degree of packing, in addition owing to have steam vent on the squeeze board, cause the back side of sand mold to exist the discrete areas that hardness is lower than the sand mold die joint, the exhaust requirements when satisfying sand casting.The utility model also has the following advantages: the sand mold back side does not have floating sand, once moves moulding, and molding sand is not had excessive demand, and the molding sand water content is 6～7%, air penetrability 67, intensity 0.80kg/cm
2, sand hardness can reach 83(A type hardness tester meter).Can utilize the original compressed air of foundry, template need not to place venting plug, and it is few to scatter sand during moulding, little to the wearing and tearing of model, therefore can utilize the existing model squeeze board of factory can make the moulding consolidated structure; Can form series of products.
The invention process is accompanying drawing for example.
