Abstract
A method of producing an iron core product may include: substantially simultaneously putting resin materials into each of a plurality of first accommodating portions formed in a heating portion; substantially simultaneously initiating heating, by the heating portion, of the resin materials disposed in the first accommodating portions; and supplying a molten resin from the first accommodating portions to resin forming regions provided in a core body.
Claims18
A method of producing an iron core product in a resin filling system including a transport portion, a heating portion, and a jig, the method comprising:
- preheating the heating portion, including a number of first accommodating portions, to a predetermined operating temperature, wherein the number of first accommodating portions are located outside a core body placed on the jig;
- placing resin materials into a number of second accommodating portions formed in the transport portion, wherein each of the number of second accommodating portions contains an equal amount of the resin materials;
- after preheating the heating portion to the operating temperature, transferring the resin materials from the number of second accommodating portions into each of the number of first accommodating portions formed in the heating portion, wherein the number of first accommodating portions equals the number of second accommodating portions formed in the transport portion;
- heating at the predetermined operating temperature, by the heating portion, of the resin materials disposed in the number of first accommodating portions in order to melt the resin materials into a molten resin having a uniform viscosity;
- supplying the molten resin from the number of first accommodating portions to resin forming regions provided in the core body that contain a plurality of magnets;
- and
- solidifying the molten resin around the plurality of magnets in the resin forming regions of the core body.
An apparatus for producing an iron core product, comprising:
- a jig configured to hold a core body;
- a heating portion where a number of first accommodating portions are formed, wherein the number of first accommodating portions are located outside the core body placed on the jig;
- a transport portion where a number of second accommodating portions are formed, wherein the number of second accommodating portions equals the number of first accommodating portions formed in the heating portion;
- an input device configured to transfer an equal amount of resin materials from the number of second accommodating portions into each of the number of first accommodating portions;
- a heater configured to initiate heating of the resin materials disposed in the number of first accommodating portions by the input device in order to melt the resin materials into a molten resin having a uniform viscosity, wherein the heating portion is preheated by the heater to a predetermined operating temperature prior to transferring the resin materials from the number of second accommodating portions into the number of first accommodating portions;
- and
- an extrusion mechanism configured to push out the molten resin in each of the number of first accommodating portions and supply the molten resin to resin forming regions provided in the core body that contain a plurality of magnets, so that the molten resin solidifies around the plurality of magnets.
