摘要： PROBLEM TO BE SOLVED: To provide a resin molding mold which can control the breakage of fibers incorporated as a reinforcing material in a resin at the branching point of a resin supply channel.
SOLUTION: At the branching point 20 where the resin supply channel is branched from a sprue 2 to runners 3, in the inner wall in the extension direction of the sprue 2, an approximately semi-spherical recess 21 for changing the flow direction of a resin is formed. Since the resin flows separately and smoothly while sneaking into the recess 21, the sharp change of the flow direction of the resin is controlled to control the increase in shearing stress, and a space necessary for the rotation etc., of the fibers can be secured when the shearing stress is applied to the fibers.

摘要： PROBLEM TO BE SOLVED: To provide an injection molding method, which can shorten a curing time of a thermosetting resin in the case that the curing time is difficult to shorten due to a blistering in the molding of the thermosetting resin.
SOLUTION: In a thermosetting resin injection molding method, a mold comprises at least two portions and heaters for heating and controlling the mold to a predetermined temperature. The method comprises a mold closing step for closing the mold to form a cavity, an injection step for injecting a thermosetting resin material into the cavity, a hardening step for hardening the thermosetting resin material into the cavity, and a mold opening step for opening the mold for taking out a hardened and molded product. When one cycle consists of steps from the mold closing step to the mold opening step, a cooling step is included, in which the temperature of a cavity forming surface is reduced during a period from the end of the hardening step to the start of the injection step of the next cycle, and mold temperature is controlled by heaters to a predetermined temperature at all times through the cycle.

摘要： PROBLEM TO BE SOLVED: To provide a plastication method for a fiber-reinforced thermoplastic resin which can stabilize a plastication time while controlling the breakage of fibers contributing to the mechanical properties of an obtained molding in a plastication process, and to provide a molding method for molding the resin effectively.
SOLUTION: In the plastication method for the fiber-reinforced thermoplastic resin, an injection molding machine has a barrel the temperature of which can be controlled individually in a plurality of zones, a hopper installed above one end on the upstream side of the barrel, and a screw which is installed in the barrel and has a compression ratio below 2. Pellets are supplied into the barrel through the hopper and melt-kneaded. The resin is plasticated under improved plastication conditions in which the feed of the resin in the barrel is controlled so that the plastication time of the first shot is 1.1-3 times as long as the plastication time of the first shot when the resin is plasticated under ordinary conditions. In the molding method, the resin is molded after being plasticated by the method.

摘要： PROBLEM TO BE SOLVED: To provide a method for molding a die in which a female screw part can be stably formed without making manufacturing processes complicated. SOLUTION: A molded article 50 is molded by filling up a molten magnesium alloy into a product part 5 of the die 1 and by cooling and solidifying it. After that, a screw-shaped pin 30 is turned. A female screw forming part 31 is rotated and retreated from a female screw part 53 of the molded article 50. By this, the female screw part 53 can be simultaneously formed during molding. Since the magnesium alloy has a property which is hardly seizable to a die material compared with an aluminum alloy, the female screw part 53 can be stably formed. COPYRIGHT: (C)2004,JPO&NCIPI
摘要翻译：要解决的问题：提供一种成型模具的方法，其中可以稳定地形成阴螺纹部分而不使制造工艺复杂。解决方案：通过将熔融镁合金填充到模具1的产品部件5中并通过冷却和固化来模制成型制品50。之后，旋转螺旋形销30。阴螺纹形成部31从模制品50的阴螺纹部53旋转并退回。由此，可以在模制期间同时形成内螺纹部53。由于与铝合金相比，由于镁合金具有与模具材料几乎难以察觉的特性，因此能够稳定地形成阴螺纹部53。版权所有（C）2004，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To produce an inexpensive magnet member having high strength by producing an unfired molding for magnet integrated with an unfired molding for yoke by filling a molding section with powder for magnet without taking out the unfired molding for yoke from the molding section. SOLUTION: An unfired molding for magnet 110 is formed by filling molding sections 210, 220 comprising a die 21, a lower punch 23, and the like, with powder 119 for magnet. An unfired molding 120 for yoke integrated with an unfired molding 110 for magnet is produced by filling the molding sections 210, 220 with powder 129 for yoke without taking out the unfired molding 110 for magnet from the molding sections 210, 220. Subsequently, both moldings 110, 120 are fired simultaneously. Since any one of magnet powder or yoke powder touches the other in the form of powder, they are brought into perfectly tight contact with no gap. Furthermore, production cost can be lowered because an integrated magnet member can be produced.

摘要： PROBLEM TO BE SOLVED: To provide a resin tank for a radiator capable of suppressing the warpage of a seal surface by allowing the degree of orientation of fibers of a seal part to approach that of a ceiling part. SOLUTION: A resin tank 1 for a radiator used for radiating the heat of the cooling water of an engine is integrally molded from a nylon 66 resin containing 30% of glass fibers as a reinforcing material. Since the wall thickness of the ceiling part 2 of the resin tank 1 is less than that of the seal part 3 of the resin tank 1, unbalance such that the orientation of fibers in the seal part 3 becomes strong and that of the ceiling part 2 becomes weak is generated. In order to prevent this phenomenon, the ceiling part 2 is formed so as to make a resin easy to flow at a time of injection molding by providing one rib part 5 to the top part of the ceiling part 2 longitudinally. By also providing an end part to the ceiling part 2, the orientation of fibers is intensified to eliminate the unbalance of the orientation of fibers of the ceiling part 2 and that of the seal part 3 to suppress the warpage of a seal surface.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing regulating device to improve sealing ability, reduce the number of part items, and reduce size. SOLUTION: A shoe housing 3 comprises a peripheral wall 4 and a front plate 5 and is integrally formed through aluminum die casting. The shoe housing 3 is formed individually from a timing gear 1. Since a housing member consists of the shoe housing 3 and a timing gear 1, the number of part items is reduced and sealing ability is improved. Further, the outside diameter of the timing gear 1 is reduced regardless of the outside diameter of the shoe housing 3. A seal member 16 is arranged at a slide part consisting of the peripheral wall 4 and a vane rotor 9. The seal member 16 is formed of a PPS resin serving as a base material and formed by mixing an inorganic filler further rigid than the PPS resin. Since the PPS resin and the mixed inorganic filler are further flexible than the shoe housing 3, a wear amount of the peripheral wall 4 is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a molding mold which can obtain a resin molding of improved appearance quality and attempt the improvement of productivity and a molding method. SOLUTION: In the molding mold, a heating means 8 which is small in size, high in output, and capable of rapid heating is installed in the neighbourhood of the cavity 7 surface of the mold. In the molding method using the mold, after the resin molding is demolded from the cavity, within a period in which a molding resin in next injected in the cavity, the cavity surface is heated by the heating means to a temperature which makes the molding resin kept molten. The heating means is turned off in a residual period in one molding cycle.
