Description

A kind of disc brake calipers body of Sand-Faced Metal Mould Casting

Technical field

The utility model relates to auto parts and components field, particularly a kind of disc brake calipers body of Sand-Faced Metal Mould Casting.

Background technique

Sand-Faced Metal Mould Casting is a kind of casting technique of the molding sand (also known as precoated sand) being covered with thin layer around metal mold (also known as swage) inner chamber.It is the combination of permanent mold casting and shell mold casting two kinds of methods.The foundry goods obtained has the advantages such as dimensional accuracy is high, good mechanical property, saving is artificial, material and facility, cost of production are low.

The production of automobile casting mainly contains common wet sand casting, cold setresin sand casting process, centrifugal casting and Sand-Faced Metal Mould Casting technique.And there is complex process in common sand mold and Reform of Resin Sand Casting fabrication technique, the tissue looseness that molding body is common, surface quality is poor, the problems such as overall mechanical properties can not be guaranteed, the shortcomings such as yield rate is low, and Sand-Faced Metal Mould Casting is covered with skim molding sand at metal mold (the being called swage) inner chamber of dumming and forms casting mold, by the weight to swage, wall thickness and the conservative control covering sand layer thickness, what make foundry goods fills type, solidify and complete under a more satisfactory condition with cooling procedure, eliminate the factor producing casting defect to greatest extent, thus greatly can improve the quality of foundry goods.In addition, Sand-Faced Metal Mould Casting adopts precoated sand moulding, and the casting dimension accuracy of production is high, and surface quality is good.Due to swage good rigidly, do not have deformability, the cast-internal dense materials of production, reject rate reduces greatly.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.

Embodiment

The utility model embodiment provides a kind of disc brake calipers body of Sand-Faced Metal Mould Casting, see Fig. 1 to Fig. 3, the disc brake calipers body of described Sand-Faced Metal Mould Casting comprises caliper body body 1, be symmetricly set on left end fixed support mounting hole site 2 and the right-hand member fixed support mounting hole site 3 at caliper body body 1 two ends, be arranged on the brake cylinder mounting groove 4 of caliper body body 1 middle upper portion, be arranged on the arrestment mechanism cap bore 5 of the middle side of caliper body body 1, be arranged on the synchronous adjustment sprocket wheel room groove 6 in the middle of caliper body body 1, be arranged on the brake disc assembly department 7 in the middle part of caliper body body 1.

Iron Mould Coated Sand technique is adopted to compare 3 advantages with traditional wet sand casting technique: 1, to save normalizing, tempering process, saved energy consumption; 2, quality gets a promotion, and product reliability is higher; 3, casting process controls well, and reject rate is low, energy-conserving and environment-protective.

Adopt Sand-Faced Metal Mould Casting explained hereafter braking clamp caliper, overcome the shortcoming of conventional casting techniques, foundry goods cools, curing condition is good, the aspect such as nodulizing grade, grain size, consistency of foundry goods has and largely improves, improve foundry goods comprehensive mechanical property, reduce costs, improve production rate, decrease the pollution of production process to environment simultaneously, achieve Green foundry technique.

The process characteristic of Sand-Faced Metal Mould Casting:

1. Sand-Faced Metal Mould Casting has the feature of sand casting process, namely has a rigidity sand mold shell, makes sand mold bulk strength high, indeformable, and its adaptability is extensive, the easy demoulding of foundry goods, and location is reliable, and precision is high.

2. Sand-Faced Metal Mould Casting has the feature of resin-coated sand shell mould casting, no matter moulding what casting sand mold convenient, fast, within two, three minutes, just mouldable is complete, and sand density, mo(U)ld face hardness etc. are ensured by equipment, forever consistent, and do not need to brush any coating.Both obtain bright and clean foundry goods, turn improve the form and dimensional precision of foundry goods.

3. Sand-Faced Metal Mould Casting also has the feature of permanent mold casting, the casting mold of iron has obvious cold shock effect in molten metal crystallization process, the refinement of casting crystalline grain degree can be made, thus improve the comprehensive strength of foundry goods, weakness simultaneously again owing to there being the existence of close-over to avoid permanent mold casting, foundry goods can not produce spoken parts in traditional operas, for ironcasting, as cast condition can produce various material, without the need to heat treatment.

4. after the casting mold locking be made up of swage and thin close-over rigidity high, be out of shape little, cooling is fast, the casting dimension accuracy obtained is high, machining allowance is little, dense structure, be particularly suitable for the production of spheroidal graphite cast iron, produce spheroidal graphite cast iron time the graphitization expansion of spheroidal graphite cast iron can be utilized to carry out from feeding foundry goods---realize spheroidal graphite cast iron less, no-riser casting, obtain premium casting; Because swage cooling is fast, especially favourable to the dish class of pearlite matrix, the bar axle class foundry goods producing the high trade mark.

5. about high 20 the HB units of foundry goods that the casting hardness that generally Iron Mould Coated Sand is produced is produced than conventional cast method.

6. after utilizing casting pouring, the waste heat of swage carries out the precoated sand solidification of recirculation production, decrease electricity consumption, and casting process presents enclosed circulation production status, produce occupation area very little (such as: during melting in a hour one ton of iron (steel) water, moulding cast area have two, 300 square metres just enough), do not need sand preparation equipment, little investment instant effect.

7. due to the Quench of swage, make molding sand can not by burning, not only molding sand can be reused, and because the roasting of casting process, thus molding sand (silica sand) is undergone phase transition, the thermal expansion coefficient of sand reduces to 5 by 15.So all right regeneration of the old sand produced in production process, meets and develops a circular economy.

The described sand molding that covers is the key link that Sand-Faced Metal Mould Casting is produced, and general employing penetrates sand-heat cure moulding.Adopt duplex position to cover sand molding machine, be exactly hot box shoot core machine, what complete upper and lower mould swage covers sand molding simultaneously.Swage temperature 200 ~ 250 DEG C is controlled, model temperature about 250 DEG C during moulding.Wherein model temperature adopts electric heating tube heating, carries out closed loop control, substantially keep temperature constant state by the temperature control system of moulding machine.When Iron Mould Coated Sand is produced, its sand mold adopts the heat cure of hot box method, and need certain temperature and time, this have impact on the manufacturing efficiency of Iron Mould Coated Sand, the mode of automatic production line can only be adopted just to be applicable to the production of typical products in mass production.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
