Detailed description of the invention
In order to further illustrate technical scheme, the detailed description of the invention of the present invention is described in conjunction with accompanying drawing, such as Fig. 1 to Fig. 8, design drawing according to pipe clamp, in this example as a example by the pipe clamp of 125 millimeters of steel pipes of diameter, pipe clamp is divided into right-hand part A and left side B, and two halves close up and penetrate locking pin, complete the connection of metal tube；The appearance and size of pipe clamp is amplified 8-12 millimeter, make pipe clamp arenaceous shell mould C, this example is selected the longitudinal median plane of pipe clamp as cast die joint, with die joint as boundary, operating efficiency, this example use every mold make the left side B of pipe clamp and the arenaceous shell of right-hand part A and core to improve simultaneously；And pipe clamp arenaceous shell mould C and pipe clamp core mold D are produced arenaceous shell upper mold 1 and arenaceous shell lower mold 2 and core upper mold 3 and core lower mold 4 centered by the die joint of pipe clamp respectively；Arenaceous shell upper mold 1 use the steel plate of thickness 50 millimeters as cope match-plate pattern 11 in this example, cope match-plate pattern 11 is produced upper left die cavity 12 respectively, left sand inlet 13, installing hole 14, right sand inlet 15, upper right die cavity 16, hole 17, location, passage 18, and match with arenaceous shell lower mold 2, the same steel plate selecting thickness 50 millimeters makes the lower bolster 21 of arenaceous shell lower mold 2, and on lower bolster 21, produce passage 22 respectively, bottom left die cavity 23, left sand inlet 24, installing hole 25, right sand inlet 26, hole 27, location, bottom right die cavity 28, arenaceous shell upper mold 1 is relative with arenaceous shell lower mold 2 die cavity open face, composition pipe clamp arenaceous shell mould C；The same steel plate cope match-plate pattern 31 as core upper mold 3 selecting thickness 50 millimeters, produces hole 32, location, upper left die cavity 33, left sand inlet 34, passage 35, installing hole 36, upper right die cavity 37, right sand inlet 38 on cope match-plate pattern 31 respectively；Select the steel plate lower bolster 41 as core lower mold 4 of thickness 50 millimeters, and on lower bolster 41, produce hole 42, location respectively, bottom left die cavity 43, left sand inlet 44, passage 45, right sand inlet 46, bottom right die cavity 47, installing hole 48, and close up relative with core lower mold 4 die cavity opening direction for core upper mold 3, alignment pin is used to insert hole, location 32 and hole 42, location respectively so that it is position is fixed；During application, by the pipe clamp arenaceous shell mould C made and pipe clamp core mold D, it is installed on the mould bases of arenaceous shell automatic moulding machine, this example uses double arenaceous shell core forming machine, pipe clamp arenaceous shell mould C is arranged on the left side mould bases of arenaceous shell core forming machine, pipe clamp core mold D is arranged on the right side mould bases of arenaceous shell core forming machine；Start the control system of arenaceous shell core forming machine, the Hydraulic Cylinder mold mounting plate of hydraulic system move the arenaceous shell upper mold 1 so that pipe clamp arenaceous shell mould C and pipe clamp core mold D and arenaceous shell lower mold 2 close to and compress, core upper mold 3 and core lower mold 4 are close and compress；The control system of arenaceous shell core forming machine passes through information acquisition system, instruction compression air system starts and opens the passage of sandbox and sand hopper, the precoated sand that proportioning is good is made to enter sand hopper and enter dies cavity by the sand export of sand hopper, precoated sand is compacted under pressure, mould is heated by control system instruction heating system, and then the precoated sand in heating mould, it is allowed to sex change solidification, temperature sensor real-time detection heating-up temperature also feeds back to control element, to control the constant of heating-up temperature；After arenaceous shell or core solidify, mould is separated by the hydraulic cylinder of control system instruction hydraulic system, takes out arenaceous shell or core, just completes the manufacturing process of arenaceous shell and core.
The arenaceous shell made and core are placed on cast place, core is put into inside arenaceous shell according to the structure of pipe clamp, fusing molten iron good for proportioning is poured in arenaceous shell, after cooling, open arenaceous shell, take out foundry goods, cast gate and rising head are removed, and clear up the impurity on spray, just complete the production of the blank of brake disc.
Due to automated production during the production of arenaceous shell and core, it is possible to produce in enormous quantities, overcome the complexity of clay-bonded sand or phenolic sand molding, save a large amount of Foundry quartz sand, reduce production cost and labour intensity；Arenaceous shell and core mold are long for service life simultaneously, overcome wooden model or the short-life shortcoming of aluminum dipping form.
