Abstract

The utility model relates to a long-wing type radiating sheet device for making sand form, which is composed of a frame type vehicle, a templet, a groove, a hydraulic assembly, and a discrete piece sandbox. The work of the hydraulic cylinder drives an eccentric wheel and a gear to rotate, and an engaged lifting rack bar goes down; the groove walks downwards, and a wing panel is drawn down from the sand mould and drives a push rod to make the sand box shed the template. The utility model has the advantages that the operation is easy to master; the labor intensity is reduced; the horizontal plane is guaranteed when the sand box is demoulded; the surface of the sand mould finished goods is flat, smooth and clean, the yield of the sand mould is high, and the quality is stable.

Description

Parliament type radiator making sank mould device

The utility model relates to the manufacturing sand mold device of long aerofoil profile fin, belongs to casting technology field.

When producing the first procedure moulding of fin in the past, the equipment that is adopted is that the fin maintenance is motionless, by hydraulic jack jack-up push rod template is upwards risen, when taking this mode to produce, labour intensity is big, operation is difficult for grasping, sand mold percent defective height, the bad control of horizontal plane when playing type, fluctuated, make fin emery stick instability easily fall bar, type is rough, directly influences the carrying out and the product quality of next process.And employed sandbox is cast aluminium, cast iron or iron plate welding, these three kinds of sandbox material flexible types, and service life is low, influences molding quality, and the time, the long fin sand mold that causes was thickeied, and material increases, and fin weight strengthens.

The purpose of this utility model provides long aerofoil profile fin and makes the sand mold device, and this device has leakage and the automatic function that rises of sandbox under the fin.

The purpose of this utility model is achieved in that it is made of frame-type car, template, type groove, hydraulic package and separate piece sandbox, and template is fixed on the chassis, the type groove is set below the template, and this type groove is located by guide rod; Fin is fixed on the type groove by connection strap location and by connecting screw rod, graftings that be meshing with each other of type figure and fin, and core print is entrenched on the template fixedlys connected with template, and lifter rack is positioned at below the type groove, fixedlys connected with the type groove on the lifter rack; Backgear is fixed on the chassis, and is connected with tooth bar and prevents tooth bar off-centre; Hydraulic cylinder is fixed on the chassis bottom, and eccentric wheel, gear tighten together and be connected gear interlock lifter rack with hydraulic cylinder by axle, make hydraulic cylinder works drive the tooth bar lifting, pressing plate is connected with support by fulcrum shaft, and support is fixed on the chassis, and push rod is connected with pressing plate by coupling spindle.

The separate piece sandbox is to be made by cast steel material, and the lateral separation is provided with reinforcement in the casing, when making sand mold, is located on template by the case awl.

The utility model is made sand mold equipment with existing fin and is compared, template is fixed on the framework by moving being improved to of original equipment, fin keeps motionless by original equipment, be improved to and be fixed on the type groove, driving tooth bar by hydraulic package descends, and then the type groove of making down walks, and causes fin to be taken out under from sand mold, drives the push rod jack-up cast steel sandbox that makes progress by pressing plate simultaneously and makes it template.Adopt that this equipment investment is few, high efficiency, reduce labor intensity, reduce operating personnel, operation is easily grasped, and sand mold yield rate height, steady quality, horizontal plane is guaranteed during the sandbox demoulding, makes finished surface flatness, fineness, the surface roughness Ra value produced all meet national standard.

Describe the utility model in detail below in conjunction with accompanying drawing:

As shown in Figure 1, 2, it is made up of frame-type car 16, template 5, type groove 7, hydraulic package and separate piece sandbox 1.Template 5 is fixed on the chassis 16, type groove 7 is set below the template 5, this type groove 7 is by guide rod 8 location, fin 2 is fixed on the type groove by connection strap 6 location and by connecting screw rod 9, the grafting that is meshing with each other of type figure 3 and fin 2, core print 4 is entrenched on the template 5 fixedlys connected with template 5, and lifter rack 10 is positioned at type groove 7 belows, fixedlys connected with type groove 7 in lifter rack 10 upper ends.Backgear 14 is fixed on the horizontal scale of chassis, and is connected with tooth bar 10 and prevents tooth bar 10 off-centre.Described hydraulic package is: hydraulic cylinder 13 is fixed on the chassis bottom, eccentric wheel 12, gear 11 tighten together and are connected with hydraulic cylinder 13 by axle, gear interlock lifter rack 10, make 10 liftings of hydraulic cylinder 13 work zone carry-over bars: pressing plate 18 is connected with support 19 by fulcrum shaft 20, support 19 is fixed on the chassis 16, and push rod 17 is connected with pressing plate 18 by coupling spindle 21.

Shown in Fig. 3,4,5, separate piece sandbox 1 is to be made by cast steel material, and the lateral separation is provided with reinforcement 22 in the casing 1, and the casing both sides are provided with flask handle 23, flask trunnion 24, and lift handle 25 also is provided with core print hole 26 on the casing, gate orifice 27 and emit oral pore 28.When making sand mold, be located on template 5 by case awl 15.

The course of work of the present utility model is as follows: hydraulic cylinder 13 work, drive eccentric wheel 12, gear 11 rotations, interlock lifter rack 10 descends, type groove 7 is down walked by guide rod 8, fin 2 is taken out under from sand mold, touching pressing plate 18 drive push rods 17 up eject when type groove 7 drops to certain position, and sandbox 1 is deviate from template.
