Description
The utility model relates to a kind of casting mould, in particular for the casting mould of ferrous metal.
At present, the method for sand casting is still generally adopted in ferrous metal casting, and complex process, production efficiency be low, part low precision in addition.The mould that the ferrous metal casting is used, because manufacturing cost height, the influence that die life is low, so far do not use widely as yet, even on the mass-produced ferrous metal foundry production line, also be in the processing range of sand casting, the motor cylinder block foundry production line of introducing from German KW company for example, the multistation machine moulding foundry production line of Beijing factory design does not all leave sand mold.
The purpose of this utility model provides a kind of novel die that is applicable to ferrous metal casting, can make more ferrous castings, changes model casting into by sand casting, thereby enhances productivity and casting quality.
The concrete solution of the utility model is: a kind of casting mould is characterized in that: this mould includes: mould bases (1), die cavity (2), cast gate lining (3), annular pressing plate (4), screw (5), pressing plate (6), screw (7), axial adjustment sheet (8), radiai adjustment sheet (9), reference column (10), (11), matched moulds bolt (12), (13).Wherein, mould bases (1) is got by steel; Die cavity (2) is made by graphite or other synthetic exotic material.Mould bases (1) is made up of two half module framves (14); Die cavity (2) is made up of two half mould chambeies (15).Cast gate lining (3) is made up of two and half cast gates linings (16).Wherein, half mould chamber (15) are contained in the half module frame (14), are provided with axial adjustment sheet (8) between half mould chamber (15) and the half module frame (14).Pressing plate (6), screw (7) are fixed on half cast gate lining (16) in the two halves mould bases (14), two halves die cavity (15) upper end.The garden ring that radiai adjustment sheet (9) is formed for a plurality of gardens arc sheet is arranged between half module frame (14) inwall and half mould chamber (15) outer wall.On the radiai adjustment sheet (9), half module frame (14) has an annular groove with half mould chamber (15) intersection, and annular pressing plate (4) is arranged in the groove, and screw (5) is fixed on annular pressing plate (4) on the half module frame (14).Be respectively arranged with two reference columns (10), (11) on half mould bases (14) two diagonal angle, be respectively arranged with on the corresponding position in second half mould bases and reference column (10), (11) two with reference column (10), (11) corresponding hole, reference column (10), (11) are sliding fit with two holes on another half module.Two-half die is fixed together by two matched moulds bolts (12), (13).Have radiating groove (17) on the two-half die.
The utility model is inlayed a die cavity (2) made from graphite or other exotic material on the mould bases (1) of steel.The steel mould bases has the favorable mechanical performance; can be with firm being fixed on the casting machine (platform) of bolt; steel mould base to the nonmetal die cavity of making play a part the palm, drive, heat radiation and protection, make that entire die can easily be carried, loading and unloading, somatotype, folding take out other part.
In order to make the molten iron that is cast in the model design radiating groove (17) on cooled and solidified, the steel mould bases faster, a large amount of heats can spread in the air through fin (also can be designed to use water-cooled structure) on demand.The graphite die cavity is to be fixed on (as shown in Figure 1, 2, 3) above the mould bases by annular pressing plate (4) and screw (5).The method (as shown in Figure 1) that gate portions also adopts exotic material to inlay.
(8) be the axial adjustment sheet, when wearing and tearing of the axial dimension of die cavity or matched moulds excesssive gap, the way that can take reconditioning die cavity end face and increase adjustment sheet is regulated, and adjustment sheet is made for suitable with stainless steel substrates.
(9) be the radiai adjustment sheet, bigger foundry goods, the insufficient strength of die cavity material own are used this adjustment sheet when needing external force to strengthen, and this adjustment sheet is designed to the annulus that two ends have the heat-resisting steel band overlap joint composition of gradient.Adjustment sheet is subjected to thermal stretching, the gradient intersection thickness at two ends increases, the average-size of garden ring internal diameter is dwindled, the inwall of adjustment sheet and mould bases matches, tight wheel is on the outer wall of die cavity, play the effect of gaining in strength, overcome the expansion rate of the expansion rate of mould bases simultaneously, the gap that between mould bases and die cavity, occurs greater than the graphite die cavity.
(10) and (11) be reference column, left and right sides two-half die is closed up accurately.(12) and (13) be the matched moulds bolt.
The operation sequence that the utility model uses separately:
1. the assembling die cavity selects for use two of axial adjustment sheets to be advisable in mould bases, and annular pressing plate is installed, and tightens hold-down screw uniformly, notices that left and right sides two-half die mating surface is parallel, and the die cavity end face should be higher than mould bases end face 0.02-0.05.
2. suitably tighten the matched moulds bolt, left and right sides two-half die is integrated.
3. temperature is poured into a mould on request.
4. after the cooled and solidified, unclamp bolt, open mould, take out foundry goods.The utility model is fit to continuous pouring, reduces the time of contact of die cavity and air as far as possible, reduces oxidation.
Manufacturing and materials of die cavity.
1. the die cavity materials are at first selected graphite for use.Graphite is a kind of exotic material, and fusing point can reach 3410 ℃.Matter is soft and crisp at normal temperatures, compression strength 300 kilograms per centimeter
2, at high temperature hardness and intensity but improve a lot, and graphite has good thermal conductivity and resistance to thermal shocks, makees mold with graphite and also has good release property.In addition in conjunction with the material of foundry goods, the quantity of production, can try out synthetic fire resistive material, for example: allocate silicate hydrolyzate liquid, calcium hydroxide and magnesia etc. into quartz sand or corundum or aluminosilicate, do shell technology with reference to model casting, difference is by the requirement somatotype of this mould and is contained in repeatedly use on the mould bases.
2. die cavity is manufactured.With graphite block, machining moulding, graphite now has been widely used in metallurgy, chemical industry, can have selected for use the graphitization piece processing of suitable specification to manufacture, graphite has good processability, but car, mill, bore, saw, file, polish, can obtain accurate dimensions and higher luminosity, for example: protruding the touching of using on the electric spark machine tool used machining graphite.With synthetic material system embryo, dry, burn till type and also can be installed on the mould bases and use through suitable reconditioning, arrangement.
3. the replacing of die cavity.When casting dimension and profile occur overproof and change, illustrate that die cavity weares and teares, should stop using the die cavity that more renews immediately, the replacing die cavity can be on board, and hot state carries out.
The utility model is poured into a mould owing to changing foundry goods into model by sand casting, thereby has the following advantages and good effect:
1. enhance productivity.Generally change the model cast into by sand casting, production efficiency can improve about 10 times.
2. casting quality is good.Cast(ing) surface luminosity improves the 3-4 level than the luminosity of sand casting, because cooling velocity can make crystallization fine and closely woven soon, has improved casting strength.
3. die manufacturing cost is low, the part in addition that volume is approximate, and mould bases can be general.18 yuan of graphite price (material price catalogue) per kilograms, low with punching block comparative material price, processing charges is low and just can use without heat treatment and surface treatment.
4. foundry can reduce sand, the favourable workers ' health of dust pollution.
