Detailed description of the invention
In order to further illustrate technical scheme, in conjunction with accompanying drawing, the specific embodiment of the present invention is described, such as Fig. 1 to Fig. 8, design drawing according to pipe clamp, for the pipe clamp of 125 millimeters of steel pipes of diameter in this example, 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 overall dimensions 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 for boundary, in order to improve work efficiency, this example adopt every mold make the arenaceous shell of left side B and right-hand part A and the core of pipe clamp simultaneously；And pipe clamp arenaceous shell mould C and pipe clamp core mold D is produced respectively centered by the die joint of pipe clamp on arenaceous shell mould 3 and core counterdie 4 on mould 1 and arenaceous shell counterdie 2 and core；Arenaceous shell adopt the steel plate of thickness 50 millimeters as cope match-plate pattern 11 on mould 1 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 counterdie 2, the same steel plate selecting thickness 50 millimeters makes the lower bolster 21 of arenaceous shell counterdie 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, mould on arenaceous shell 1 is relative with arenaceous shell counterdie 2 die cavity open face, composition pipe clamp arenaceous shell mould C；The same steel plate cope match-plate pattern 31 as mould on core 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 respectively on cope match-plate pattern 31；Select the steel plate lower bolster 41 as core counterdie 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 counterdie 4 die cavity opening direction for mould on core 3, alignment pin is adopted to insert hole, location 32 and hole 42, location respectively so that it is position is fixed；During application, the pipe clamp arenaceous shell mould C and pipe clamp core mold D that will make, it is installed on the mould bases of arenaceous shell automatic moulding machine, what adopt in this example is 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 on the arenaceous shell so that pipe clamp arenaceous shell mould C and pipe clamp core mold D mould 1 and arenaceous shell counterdie 2 close to and compress, on core mould 3 and core counterdie 4 close to 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, control system command heating system mould is heated, and then the precoated sand in heating mould, so as to degeneration solidifies, 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 controlling system command 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 braking dish。
Automated production during due to 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 labor intensity；Arenaceous shell and core mold long service life, overcome wooden model or the short-life shortcoming of aluminum dipping form simultaneously。
