摘要： PURPOSE: To compress the molding sand by providing an opening hole communicated with a vacuum device and a compression plate hung down so as to be vertically shiftable in a closed cover and air-tightly possible to insert into a tapered stepping part of a closed cover and using a machine having low mechanical rigidity and strength. CONSTITUTION: When the pre-compression completes, a solenoid valve 33 is stopped to work and a piston 30 is descended to close a suction pipe 28. A solenoid 26 is again worked to discharge the air in the closed space. At the time of reaching a prescribed vacuum pressure, the solenoid valve 26 is stopped to work and a solenoid valve 34 is worked to descend the compression plate 23. When a seal 23a inserts into a small cross sectional area part 18a of the closed cover 18, a limit switch 21b is worked with a guide pin lever 21a and the solenoid valve 33 is worked with this signal and again, the piston 30 is floated up and the air quickly flows into the closed space through the lower part 31 of the piston and the suction pipe 28. The compression plate 23 is quickly pressurized toward the free surface of the molding sand 14 by the pressure difference between the upper and the lower surfaces and collided to the molding sand 14 at high speed to compress the molding sand.

摘要： PURPOSE:To keep the momentum of blasting material jetted from a nozzle within the specified range by controlling the pressure or the quantity of the blasting material while making direct measurement of the momentum of the blasting material which is the final target to be controlled. CONSTITUTION:The momemtum of the blasting material is measured on the time point by moving a blasting strength detector which detects the momentum generated through collision of the ejected blasting material in front of an ejecting nozzle. On the basis of the measured results, an arrangement is made so that the momentum of the blasting material may be kept within the specified range by controlling the pressure of the compressed air, the quantity of the blasting material to be supplied or the blasing time.

摘要： PURPOSE:To allow secure joining by inserting a ceramics cylindrical body into a foamed resin body having projections on the circumferential surface of a cylindrical shape to form a cavity, packing a molding material contg. no binder therein to form a buffer layer and pouring a molten metal into the cavity to form the internal chill body. CONSTITUTION:The ceramics cylindrical body 4 is inserted into the cylindrical foamed resin body 1 having many projections 3 on the inside surface consisting of polystyrene. A box-shaped molding flask 6 having an air permeable structure is provided with a box body 8 having a reduced pressure chamber 7. The foamed resin body 1 is set onto an upper molding flask 6 coated with a mold coating material at need and the molding sand 11 without contg. the binder is packed into the cavity part between the molding flask, the foamed resin body and the ceramics cylindrical body. The front surface of the molding flask excluding a sprue 2 is hermetically sealed by a heat resistant hermetic sheet 12. After the air in the flask 6 is evacuated via a reduced pressure chamber 7 by a vacuum pump, etc., a molten Al alloy is poured from a sprue. The foamed resin body 1 is evaporated by combustion and the internal chill body of ceramics is produced. The shell part of the ceramics internal chill body is automatically cast in this way.

摘要： PURPOSE:To make it possible to quickly form a compact at constant speed without developing the clogging of the fine pores of the porous solid of a base by a method wherein the base consists of an air-permeable porous solid having the required strength and at the same time a permeable membrane is made on a cavity surface. CONSTITUTION:After a porous solid 1 such as sintered metal type one or the like is installed in a bottom frame 2, a permeable membrane 3 is made on a cavity surface 1a by applying solution, the base material of which is organic polymeric resin such as polymic acid or the like, and drying. Next, a releasing membrane 4 is made on the permeable membrane 3 by applying releasant in order to obtain a bottom force 5. Similarly, after a porous solid 6 is installed in a top frame 7, a permeable membrane 8 and a releasing membrane 9 are made on a cavity surface 6a, resulting in obtaining a top force 10. At forming, the top and the bottom forces are registered so as to form a cavity 11, into which slurry-like ceramic is forced from an inlet 14 under the state that sucking action is applied on the cavity surfaces 6a and 1a.

摘要： PURPOSE:To improve the strength of a casting mold by penetrating an adhesive agent liquid to the surface of a green sand mold so that the liquid reacts and solidifies by contacting with the moisture of the mold. CONSTITUTION:Green sand is first squeezed to form a master mold 3 in a molding flask 1 and to form a cavity surface 2. The adhesive agent liquid which reacts and solidifies with the moisture as a catalyst is coated on the surface 2 and is penetrated therein. The master mold 3 penetrated with the adhesive agent liquid is thereafter rested in the atmosphere. The adhesive agent liquid solidifies in several minutes by contacting with the moisture incorporated into the mold 3 according to the above-mentioned method. A hard cured surface 4 is thus formed on the cavity surface of the mold 3. The strength of the cavity surface 2 of the green sand mold 3 and the mold 3 is thereby remarkably improved.

摘要： PURPOSE:To mold easily and efficiently a self-curing casting mold by storing the sand mixed with a binder and curing agent in a hopper and sucking said sand through a release hole at the bottom plate of a hopper into a molding flask under the reduced pressure below said plate while leveling off the height of the sand by an impeller. CONSTITUTION:The aperture of the molding flask 8 placed on a pattern board 1 is hermetically closed by the bottom plate 11a of the hopper 9 lowered by the actuation of a cylinder 10, thereby forming a hollow chamber C. On the other hand, the sand supplied from a hopper 31 and the binder and curing agent for molding the self-curing casting mold to be supplied respectively from conduits 33, 34 are added and mixed in a mixing vessel 23 provided with the impeller 26 and thereafter the mixture is supplied through the release port 28 into said hopper 9. The sand is stored in the hopper 9 while the height is leveled off by the impeller 22 attached to the vertical revolving shaft 21 of a motor 20. The inside of the hollow chamber C is then sucked and evacuated through the hollow chambers 2, 16 of the pattern plate 1 and the plate 11a by a vacuum pump 7 to suck and pack the sand in the hopper 9 into the chamber C; further the hopper 9 is lowered by the cylinder 10 to squeeze the sand if necessary. The packed sand is cured in this state and the self-curing type molding sand is thus obtd.
