Abstract
An apparatus and a method for manufacturing a reactor capable of both absorbing a dimensional variation of a core and preventing deformation due to a resin pressure during molding are provided. An apparatus for manufacturing a reactor is provided with a core. The apparatus includes a mold including a cavity for housing the core. The mold includes a plurality of pins protruding into the cavity. When the core is disposed in the cavity, at least one of the plurality of pins is not fixed, and each of the pins functions as a positioning pin. When a molded article is molded, the pin is fixed, and each pin functions as a core support pin for supporting the core against a resin pressure during molding.
Claims6
An apparatus for manufacturing a reactor including a core, the apparatus comprising:
- a mold including an upper mold, a lower mold, and a cavity for housing the core, wherein
- the lower mold includes a plurality of pins protruding into the cavity,
- when the core is disposed in the cavity, at least one of the plurality of pins is not fixed, and each of the pins functions as a positioning pin,
- when a molded article is molded, the at least one pin is fixed, and each pin functions as a core support pin for supporting the core against a resin pressure during molding, and
- the lower mold includes a wedge, the upper mold includes a wedge pressing pin, the wedge pressing pin starts pressing the wedge in response to a lowering of the upper mold, and the at least one pin is fixed by the wedge when the lowering of the upper mold is completed.
A method for manufacturing a reactor including a core, the method comprising:
- disposing the core in a mold including an upper mold, a lower mold, and a cavity for housing the core;
- and
- molding a molded article by using the mold, wherein
- the lower mold includes a plurality of pins protruding into the cavity,
- in the disposing of the core, at least one of the plurality of pins is not fixed, and each of the pins functions as a positioning pin,
- in the molding of the molded article, the at least one pin is fixed, and each pin functions as a core support pin for supporting the core against a resin pressure during molding, and
- the lower mold includes a wedge, the upper mold includes a wedge pressing pin, the wedge pressing pin starts pressing the wedge in response to a lowering of the upper mold, and the at least one pin is fixed by the wedge when the lowering of the upper mold is completed.
