摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing an electromagnetic device, in which an opening and a boundary part causing partial discharge do not exist in a resin material, in which, at least an outer periphery on the high-voltage side in a transformer compact, is wrapped. SOLUTION: The low-voltage side of the transformer compact is held with a holding part by using a resin forming metallic mold having a cavity, into which the transformer compact is inserted and melting resin is implanted, the holder holding the low-voltage side of the transformer compact, a low-voltage side gate arranged at the low-voltage side of the transformer compact, and a high-voltage side gate arranged on the high-voltage side of the transformer compact. Melting resin which is melted is implanted in the cavity from the high-voltage side gate. Molten resin is injected from the low-voltage side gate into the cavity at prescribed timing, when the molten resin externally wraps the high voltage of the transformer compact. The whole transformer compact is sealed with a resin material. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic device preventing a breakdown. SOLUTION: A transformer structure is sealed by an insert molded form in an electromagnetic device, and the insert molded form is molded by wrapping the transformer structure without an opening section and a boundary section by a resin material filled around the transformer structure. A metal mold for molding a resin can advance in a cavity, and has a holding member retractable from the inside of the cavity with a filling to the periphery of the transformer structure of the injected resin material. A manufacturing method for the electromagnetic device is composed of a process in which the molten resin material is injected into the cavity in which the transformer structure held by the holding member is interpolated; and a process in which the holding member is retracted at a timing when the resin material is filled while wrapping at least a part of the outer periphery of the transformer structure, and a space section formed by the retraction of the holding member is filled with the resin material.

摘要： PURPOSE: To improve productivity by eliminating the runner resin from being pulled so as to be elongated and teared off by a method wherein a protruded piece extending to a gate opening side is protrusively provided from the locking projections of a runner locking pin. CONSTITUTION: After the cooling down and solidification of resin 7, a mold is opened from a parting surface P1. Since a runner locking pin 1 is pushed up by means of a large diameter head part 1c locating at the spot-faced part 2a of a fixed side mounting plate 2, resulting in moving together with the fixed side mounting plate 2 and a runner stripper plate 3. At this time, since the cooled-down and solidified resin 7 holds a runner 4a by biting on the two invertedly tapered locking projections 1a of the runner locking pin 1, the molded body 8 in a cavity 4c is torn off and broken from a gate opening 4b.

摘要： PURPOSE:To prevent a disconnection of a winding and a damage or break of a coating by a post forming method wherein a resin is made to flow approximately in parallel to the coil winding direction, and the weld end part of the resin is formed on a position other than the coil. CONSTITUTION:On the both sides of a gate 15 of an injection mold, shielding pins 14 provided on the mold are positioned to direct a pressurized resin flow from the gate 15 as shown by arrows A, B while preventing it from being directed to the both sides. A recessed part 17 is formed in the mold. A large amount of resin is led into the recessed part 17, thereby also directing the resin flow in the direction B. In this manner, the resin is made to flow in the length direction of a winding in the vicinity of the coil 1. The following troubles can be prevented from ocurring: a resin molding pressure is applied in the shearing direction of the winding of the coil 1 in the vicinity of the coil 1, thus resulting in the disconnection of the winding, and the windings are rubbed with each other so strongly that the coating thereof is broken.

摘要： PURPOSE:To make it possible to have a smooth cut gate surface at the molding, in which resin is poured through a side gate by a method wherein the side gate is forcibly cut by being pinched between a punch and a die, which supports the under surface of a molded item and, after that, a runner lying on the die is thrust down with an ejector pin. CONSTITUTION:A die 2, which supports the under surface of a molded item, is so constituted as to abut against the sharpened tip of a punch 3. Durint the lowering of the punch 3, a side gate 40 is forcibly cut by being pinched between the die 2 and the punch 3. Since a runner 4 is under the state being supported by the die 2 at the cutting of the side gate 40 and left on the die 2 after the cutting of the gate, an ejector pin 35 is seperately provided so as to thrust down the runner 4 by driving the ejector pin 35 downwards after the finish of the cutting of the gate.

摘要： PURPOSE:To make a mechanism to slide a jig in a mold for secondary molding unnecessary by a method wherein the positioning of a primarily molded body is done by shifting the primarily molded body rectangular to the direction of mold closing through the abutting of the inclined edge face at the tip of a pressor, which is provided in a mold, against the inclined plane of the primarily molded body. CONSTITUTION:A cord block caulking device is produced by jointly providing a palletizer 71, which feeds the primarily molded body 41 of a table tap 4, and a palletizer 72, which feeds the primarily molded body 51 of a power plug 5. A molding device 8 consists of two molders 80, onto which molds 2 and 3 are set respectively, and a circulating path 83, which circulates molding assisting frames 1, passes through the arranging sections of the molds 2 and 3 and on the cord block caulking device 7 side of which a setting section 81 is provided and on the characteristics inspecting device 9 side of which a removing section 82 is provided. Two sets, each of which is produced at the cord block caulking device 7 by attaching the primarily molded bodies 41 and 51 to both sides of a power cord 6, are set to the molding assisting forms 1 at the setting section 81. After the completion of molding, each set is removed from the molding assisting forms 1 at the removing section and, after that, sent to the characteristics inspecting device 9 side.

摘要： PROBLEM TO BE SOLVED: To connect a pressure introducing pipe to a pressure feeding pipe without a connecting member on user's side by forming a threaded part on the tip end of the pressure leading pipe. SOLUTION: A base 1 is integrated with a pressure introducing pipe 2 by an insulative resin. The pipe 2 is provided with an external thread 2f on its tip end that is engaged with an internal thread 4b provided in a pressure feeding pipe 4. Thus, the threads 2f and 4b constitute a screw engaging part 24, and while an O ring 5 is held by compression between a flange part 2d of the pipe 2 and one end 4c of the pipe 4, the pipe 2 is connected with the pipe 4. Therefore, the accuracy of measurement can be improved without leaking of fluid such as air, etc.
