Combined mold for making inductors

Abstract

The invention discloses a combined type die for manufacturing inductors. The combined type die is provided with a forming die located on a die holder of a punching machine, wherein the forming die is provided with a lower punch, and a stock mold located on an upper mold plate of the punching machine, wherein the stock mold is provided with an upper punch; and the combined type die is further provided with a moving jig with mobility, wherein the moving jig is provided with a forming space which penetrates a top surface and a bottom surface of the moving jig. When an inductor is manufactured, the forming space of the moving jig is used to hold coils of materials and to hold a magnet conductive powder; the materials are transferred along with the moving jig to be arranged between the forming die and the stock mold to be subjected to cutting and extrusion molding; and the moving jig is moved away from the position between the forming die and the stock mold and is baked, so that the magnetic conductive power inside the forming space is cured to form a inductor. And the finished product yield is increased and inductor manufacturing is facilitated.

Description

Technical field [0001] The present invention relates to the field technology of a combined mold for making inductors, in particular to the combined mold is provided with a mobile jig with mobility, and the molding space of the mobile jig is used to supply the coil of the material and fill with the magnetic powder , And can bake the mobile fixture to solidify the magnetic powder to form the body, improve the yield of the inductor, and facilitate the manufacture of the inductor. Background technique [0002] Press, when making general inductors, please refer to Taiwan Patent No. I441209, which is in the cavity of the forming die of the press machine. The above method of stamping and cutting presses the coil into the cavity to make the coil form two The electrode point is close to the side wall of the cavity, and the iron powder is continuously filled into the cavity, and then the iron powder is squeezed by the punching machine, so that the iron powder and the coil form a semi-finis...

Problems solved by technology

[0002] Press, when making general inductors, please refer to China Taiwan Patent No. I441209. It is in the mold cavity of the forming mold of the stamping machine, and the coil is pressed into the mold cavity by stamping and cutting the above mold, so that the coil forms two The electrode point is close to the side wall of the mold cavity, continue to fill the iron powder into the mold cavity, and then use the punching machine to squeeze the iron powder, so that the iron powder and the coil form a semi-finished inductor, and then the semi-finished inductor is taken out of the mold cavity and baked However, when the upper and lower molds are positioned on the punching machine, they must first go through procedures such as alignment correction. Therefore, when the upper and lower molds are installed on the punching machine, they cannot be easily moved. It must be re-calibrated, causing inconvenience in use, and because the mold cannot be moved, the semi-finished inductor that has not been baked and fixed must be taken out of the mold cavity for baking and setting operations. However, the coil inside the iron powder will be heated at the same time. Expansion occurs, which makes the iron powder easy to crack when it is baked and solidified, resulting in a decrease in product yield
