| PURPOSE:To obtain easily and in a short period a casting plan with which castings having no shrinkage cavity are manufactured by giving necessary data on the basis of the analytical model set with the shape of the casting and casting mold, making the temp. gradient distribution chart of the casting by numerical analysis and evaluating the analytical model from said chart. CONSTITUTION:An element breakdown chart is made by a mesh generator on the basis of each basic shape of the casting 1 and casting mold 2. Density, specific heat and heat conductivity are given to each element, latent heat and the relation between temp. and solid phase rate are given to the casting and further the heat conductivity determined by boundary conditions is given to the respective boundary parts of (atmosphere and casting), (casting mold and casting) and (atmosphere and casting) then a numerical analysis is executed. The temp. distribution chart at the solid phase rate above the threshold solid phase rate for the generation of the shrinkage cavity is made from the results thereof and the part where the shrinkage cavity is liable to arise is predicted therefrom. For example, the part where the temp. gradient is low, i.e., the lower part of a flange and the opposite surface of a chiller 3 are predicted to have an easy tendency to the shrinkage cavity. | ||||||

| PURPOSE:To fill a gypsum slurry to a matrix having steep slopes and to obtain an excellent roll-over gypsum model by subjecting alternately the matrix surface on which a parting material is coated to adhering of woven fabrics stuck with calcined plaster powder with coating of a gypsum slurry and coating of the gypsum slurry. CONSTITUTION:When the woven fabric 4a stuck preliminarily with the calcined plaster powder is adhered to the matrix surface right after coating of the gypsum slurry, part of the water in the gypsum slurry is absorbed in the calcined plaster powder and therefore the viscosity of the gypsum slurry increases and even if the matrix surface has the steep slopes, the gypsum sticks stably to the matrix surface without drooping. On the other hand, the fabric 4a stuck with the calcined plaster powder is progressed in curing by the moisture absorbed from the gypsum slurry by which the fabric is laminated and integrated to the gypsum slurry. The coating of the gypsum slurry and the adhering of the woven fabric stuck with the calcined plaster powder are further repeated a required number of times. Posts 5 are finally erected at suitable points and the molding is removed from the matrix surface, by which the roll-over gypsum model reinforced with the fabrics 4a, 4b is obtd. | ||||||

| PURPOSE:To form a model of a metallic mold for precision casting having a good surface condition with eacy working of the model without the distortion thereof in the manufacture of said model by working a rigid urethane resin to the model of the casting mold allowing for shrinkage allowance of a casting material. CONSTITUTION:The rigid urethane resin has suitable hardness, excellent workability and uniform material density and is therefore unaffected by a temp. change and humidity and surface finish is smooth. The satisfactory model having the good surface finish without the distortion is thus obtd. if the model of the casting mold allowing for the shrinkage allowance of the casting material is worked and manufactured of such rigid urethane resin. | ||||||

| PURPOSE:To obtain a resin pattern which permits casting of a casting mold having a three-dimensionally curved surface with good dimensional accuracy by pouring a resin liquid into plural split patterns combined with plural negative patterns molded of a resin by using a wooden pattern and solidifying the resin liquid. CONSTITUTION:The negative pattern 14 for the front of a product pattern, negative pattern 18 for the rear and the negative pattern 21 for the embedding surface are molded of the resin by using the wooden vane pattern. The respective negative patterns 14, 18, 21 are combined to form the split resin pattern A. The sprue pattern is removed therefrom and the resin liquid is poured through a sprue 22 into a space 23 and is cured by which the resin pattern 24 for a casting mold for the vane of an impeller, etc. is obtd. The many resin patterns for casting having the same shape as the shape of the wooden pattern are produced by the above-mentioned method, by which the product pattern having high dimensional accuracy is produced at a low cost. | ||||||

| PURPOSE:To provided the titled pattern which speeds up curing of a casting mold by using foamed gypsum in the pattern part corresponding to the part of the casting mold where curing is not enough thereby providing air permeability to the pattern. CONSTITUTION:A binder such as furan is added to the sand of a casting mold and the sand is cured by heating for which evaporation of the moisture in the binder is necessary. Foamed gypsum is made into a piece and such piece is fitted into the pattern part where the venting is poor to improve air permeability and to speed up curing. Since the gypsum has the coefft. of dielectric loss approximately equal to the coefft. of dielectric loss of wood, there is no possibility of overheating by high-frequency heating. | ||||||

| PURPOSE:To reduce the weight of a pattern and to improve machineability, etc. by packing a waste material into the cavities of a skeleton, embedding the mixture composed by compounding adequate amts. of lightweight aggregate, furan resin or urea resin and acid into the cavities and molding the surface. CONSTITUTION:Skeletal materials 1-4 for a pattern are made of wood and a prototype is formed. Left-over pieces such as wooden pieces and styrene balls are put into the spaces in such skeleton and thereafter the mixture composed by adding 20-60pts. a furan resin or urea resin (liquid) and 1-10pts. acid such as sulfuric acid as a catalyst to 100pts. granular lightweight aggregate is embedded therein. The surface thereof is then cut away to the specified size, by which a solid pattern is perfected. The similar result is obtd. by adding further 5-10pts. a polyester resin or epoxy resin (liquid) and 0.5-1pt. curing agent to 100pts. the lightweight aggretate. Since the light material and plastic material are used, the weight and cost are both reduced. | ||||||

| PURPOSE:To upgrade the accuracy of forming a casting mold and to improve the service life of a wooden pattern by constituting the wooden frame in the wooden pattern of a skeleton assembled of reinforcing core materials such as metallic sheet and rods as well as rail members such as timber or the like fitted embracively to the surface of said core materials. CONSTITUTION:Reinforcing core material such as a metallic sheet or rod is used for a core material 25 forming a skeleton of a wooden frame 20 in a wooden pattern. A rail member 26 consisting of sized timber or the like is fitted embracively to the surface of the material 25. The embracive fitting of the core material and the member 26 is accomplished by providing, for example, through- holes (h) and fixing both by screwing, etc. Plate materials 30 are adhered to the inside and outside surfaces of the frame 20 formed in the above-mentioned way to complete the wooden pattern. The accuracy in molding is thus improved without generating deformation and damage of the wooden pattern during transportation and molding and the service life of the wooden pattern is improved. Such wooden pattern is suitable for manufacturing the large-sized wooden pattern into one body. | ||||||

| PURPOSE:To enable reduction in the weight of a pattern for a casting mold consisting of silica sand and a resin and to improve workability and safety by compounding a heat insulating and lightweight weight reducing agent having microwave transmittivity in a reinforcing material constituting the pattern. CONSTITUTION:A heat resistant rubbery layer 1 having the sectional shape corresponding to the shape of a desired casting mold is deposited on the inside enclosed circumferentially by a metallic flask 3, and a heat insulating and lightweight weight reducing agent having microwave transmittivity, for example, pearlite or the like is compounded with the component of a reinforcing material consisting of silica sand as an essential component and a resin such as an epoxy resin in about 20-100wt% range basing on the weight of the silica sand; further, the other reinforcing material and curing accelerator are added thereto, if necessary, to select the suitable strength of the material 2 according to the kind of the casting mold. The reduction in the weight of the pattern is thus made possible without spoiling the curing characteristic of the casting mold by microwave heating and the case of handling and safety are improved. | ||||||
