Hot press molding method for inductor

A hot press molding method for an inductor, comprising:

• S1:
• manufacturing two inductance coils, a first magnetic powder block and two second magnetic powder blocks;
• wherein, the two inductance coils are both in a U shape, and a first side of the first magnetic powder block is provided with two embedding grooves;
• depth directions of the two embedding grooves are parallel to each other;
• in the step S1, each of the two second magnetic powder blocks comprises a first block and a second block, the first block is provided with a first inclined surface, and the second block is provided with a second inclined surface;
• S2:
• placing the two inductance coils into the two embedding grooves respectively;
• wherein, pins of the two inductance coils are arranged outside the two embedding grooves;
• S3:
• placing the two second magnetic powder blocks into the two inductance coils respectively;
• wherein, the two second magnetic powder blocks are attached to inner walls of the two inductance coils and the two embedding grooves respectively;
• S4:
• hot-pressing the two inductance coils, the first magnetic powder block and the two second magnetic powder blocks by a hot pressing mold;
• wherein, the first side of the first magnetic powder block is set as a first hot pressing surface, and a second side of the first magnetic powder block away from the two embedding grooves is set as a second hot pressing surface;
• in the step S4, the two second magnetic powder blocks are placed in the two embedding grooves respectively;
• when the two inductance coils, the first magnetic powder block and the two second magnetic powder blocks are hot-pressed, the first inclined surface abuts against the second inclined surface, and the first block and the second block move away from each other;
• S5:
• performing rolling spraying on the two inductance coils, the first magnetic powder block and the two second magnetic powder blocks;
• S6:
• stripping paint from the pins of the two inductance coils;
• and
• S7:
• electroplating the pins of the two inductance coils.
