摘要： PURPOSE:To prepare easily a metal mold having a complicated surface shape, by flame-spraying a specified thickness of a metal having high hardness on the surface of a resin mold obtained by casting a surface resin contg. a metal powder on the recess surface of a female mold obtained from a metal original mold to prepare a metal surface coating, and by grinding the surface. CONSTITUTION:An original mold 1 which is the standard of the metal mold to be prepd. is placed on a machine platen 2. After the original mold 1 is surrounded by a frame 3, a female mold 4 is prepd. with a resin, plaster and so on inside of the frame 3. A mold lubricant is applied on the surface of the cavity 4 and a surface forming resin 6 contg. 10 to 2,000pts.wt. of a metal powder 5 such as cast iron powder, steel powder and special steel powder and so on per 100pts.wt. of a thermosetting resin is thereafter molded in the female mold 4 and a backup material 7 such as cast iron or aluminum and so on is then molded to prepare a resin mold 8. A part of the metal powder 5 in the surface layer of the surface forming resin 6 is exposed on the surface by cleaning up the surface of the surface forming resin 6 and a specified thickness of a flame-sprayed metal layer 9 is thereafter spray-coated by flame-spraying. A metal mold of good quality can be obtained by grinding the surface of the flame- sprayed metal layer 9 thereafter.

摘要： PURPOSE:To form a master pattern for casting so as to have adequate workability and compressive strength and to provide a smooth surface having low water absorptivity thereto by putting the prefoamed particles of a crosslinked PP resin having a specific gel fraction into a mold and heating the same to expand to the specific density and average cell size. CONSTITUTION:Adequate amts. of water, antisticking agent talc, org. peroxide crosslinking agent such as 1,1-bis(t-butyl peroxy)3,3,5-trimethyl cyclohexane and crosslinking assistant divinyl benzene are added to the PP resin such as ethylene/propylene random copolymer having density and 70-1,000mum average cell size is obtd. The good master pattern for casting having the adequate cutting workability, compressive strength, smooth surface and low water absorptivity is thus obtd.

摘要： PURPOSE:To improve wear resistance and to facilitate prepn. by forming a surface layer consisting essentially of ceramic powder and synthetic resin on the surface of a pattern to a specific thickness. CONSTITUTION:A product part 3, a riser part 4 and a runner part 5 are respectively fixed to a plate 2 to form the pattern 1 consisting essentially of an epoxy resin. A coated film 8 consisting essentially of an urethane resin and ceramic (Al2O3) powder is formed in the surface layer part 7 of the base body 6 of the pattern 1 to a 10-200mum range. A paint prepd. of a mixture composed of the urethane resin, ceramic powder, pigment, thinner, etc. is sprayed by an air spray gun to form a coated film 8. The wear resistance of the pattern 1 is improved by the intervention of the film 8 contg. the ceramic powder and since the method for spraying the paint by a spray gun is adopted, the prepn. is facilitated.

摘要： PURPOSE:To produce a casting mold without defective degassing by disposing vent hole forming members in the positions where said members face at one end the inside wall of the molding space of a seed mold, casting a pattern material into the molding space and working the vent hole forming members after solidification. CONSTITUTION:The vent hole forming members 2 are disposed in the positions were the members face at one end the inside wall 6 in the molding space of the seed mold 4. The liquid or molten pattern material is cast into the molding space and after the pattern material solidifies, the members 2 are worked to form the vent holes. The disposition of the vent plugs in the workable positions is thereby make possible and therefore the casting mold is produced without the defective degassing.

摘要： PURPOSE:To dispose a vent plug to a desired position and to produce a casting mold without generating defective degassing, etc. by disposing pipes which communicate at one end with vent plugs and communicate at the other end with the outside of a pattern body into the pattern body. CONSTITUTION:The pipes 3 which communicate at one end with the vent plugs 2 and communicate at the other end with the outside of the pattern 1 body are disposed into the pattern body. The disposition of not only the molding board and limited pins for ejection in the pattern part corresponding to the points where degassing is required in the stage of forming the casting mold but also the disposition of the vent plugs 2 in the desired positions are thus made possible. The casting mold is thereby produced without the defective degassing, etc.
