Description
Technical field
The present invention relates to the sectional die field technologies of production inductor, and the sectional die is espespecially provided with tool and moves
The movement jig of dynamic property, the molding space using mobile jig can be toasted for being placed in the coil and filling magnetic conduction powder of materials and parts
Mobile jig solidifies magnetic conduction powder and forms ontology, improves the finished product yield of inductor, and facilitates manufacture inductor.
Background technique
Press, general inductor please refers to TaiWan, China patent I 441209 when production, be in punch table at
In the die cavity of pattern tool, coil is pressed into die cavity by the mode that the above mould punching is cut, and so that coil is formed two electrode points close
In die cavity side wall, continue in filling iron powder to die cavity, reuse punch table and squeeze iron powder, iron powder and coil is allowed to form semi-finished product cell
Sense then by this semi-finished product inductance by taking out in die cavity, and carries out baking sizing and electrode slice is arranged, however, due to
When upper/lower die is positioned at punch table, it is necessary to first pass through to programs such as bit corrections, therefore upper/lower die is installed on punch table
When, just can not move easily, once by movement, must just re-calibrate, cause using upper inconvenience, and due to its mold without
Method is mobile, it is therefore necessary to unbaked fixed semi-finished product inductance is subjected to baking sizing operation by taking out in die cavity, however
The coil of iron powder inside can generate expansion because heated simultaneously, make iron powder when baking-curing, be easy to produce the situation of cracking, cause
Product yield decline.
