Description

Technical Field

[0002] T-Core inductor is a manufacturing process used for ultra-thin and small-size one-piece molded inductors. With the rapid development of the information society, electronic products have been developing in the direction of "miniaturization, integration, multi-function, and high power". Traditional one-piece molded inductors can no longer meet the needs of downstream consumer electronics, automotive electronics, communication electronics and other industries, and the demand for ultra-thin and small-size one-piece molded inductors with smaller size, lower cost and excellent performance is gradually increasing.

[0003] The advantage of the T-Core process in making ultra-thin, small-size, one-piece molded inductors is that the magnetic core can be hot-pressed first and then the coil can be wound. This not only shortens the production process and saves costs, but also has better performance. It uses ultra-high magnetic permeability magnetic powder with an independent formula, and deeply integrates magnetic powder optimization with wire design to achieve a thin design while providing high-performance products as much as possible. However, most of the hot pressing molds in the existing technology are single-mode, which is not convenient for multiple hot pressing operations at the same time, and the hot pressing efficiency is low. The single-mode hot pressing mold has a low utilization rate of the press, which is easy to cause energy waste. In addition, if the hot pressing efficiency is to be improved, multiple hot pressing molds need to be used and occupy a large space, resulting in high production costs. Utility Model Content

[0024] Reference Figures 1 to 4 The inductor double-mode hot pressing mold shown includes a pair of inductor carriers 1, which are used to hold inductor hot pressing powder, and also includes a pair of mold bases 2, an upper mold 3 and a lower mold 4. The upper mold 3 and the lower mold 4 are respectively installed on the two mold bases 2, and the two mold bases 2 are symmetrically arranged up and down. The inductor carrier 1 is detachably installed on the top of the lower mold 4, which is convenient for taking out the inductor carrier 1, so as to continuously perform hot pressing on multiple different inductor magnetic cores. A plurality of mold cavities 10 are opened on the top of the inductor carrier 1, and two groups of hot pressing needles 30 are fixedly connected to the bottom of the upper mold 3. The two groups of hot pressing needles 30 are symmetrically distributed at both ends of the upper mold 3, and the hot pressing needles 30 are plugged into the mold cavities 10. The total number of the two groups of hot pressing needles 30 is 112, which just cooperates with the mold cavities 10 on the two inductor carriers 1 for hot pressing operations, so that the utility model can simultaneously perform hot pressing operations on the inductor hot pressing powder on the two inductor carriers 1, thereby improving the hot pressing efficiency and making full use of the kinetic energy of the press, saving energy and reducing production costs.

[0025] A slide groove 40 is provided on the top of the lower mold 4, and the slide groove 40 is slidably connected to the inductor carrier 1. The two inductor carriers 1 fit together, and the two inductor carriers 1 can be fixed on one lower mold 4 at the same time, saving space. An L-shaped protrusion 41 is fixedly connected to the top of the lower mold 4, and the bottom of one side of the L-shaped protrusion 41 fits together with the top of the inductor carrier 1. The inductor carrier 1 is moved to slide along one end of the slide groove 40 until one end of the L-shaped protrusion fits with the inductor carrier 1. At this time, the inductor carrier 1 is located in the lower mold 4 and cannot move up and down, ensuring the stability of hot pressing.

[0026] A plurality of limiting rods 31 are fixedly connected to the bottom of the upper mold 3, and a plurality of semicircular grooves 11 are provided on the inner walls of both sides of the slide groove 40 and both sides of the inductor carrier 1, and the two semicircular grooves 11 form a circular groove structure, and the semicircular grooves 11 are plugged and matched with the bottom of the limiting rods 31. When the upper mold 3 moves downward, the two semicircular grooves 11 are interconnected to form a circular groove, and the limiting rods 31 are inserted between the two semicircular grooves 11, so that the inductor carrier 1 cannot move horizontally in the slide groove 40, further ensuring the stability of hot pressing, and when the limiting rods 31 leave the semicircular grooves 11, the inductor carrier 1 can move freely along the slide groove 40, which is convenient to use.

[0027] The mold base 2 includes a mounting plate 20, a heat insulation plate 21, a heating plate 22 and a fixing plate 23. The mounting plate 20, the heat insulation plate 21, the heating plate 22 and the fixing plate 23 are stacked in sequence and fixedly connected by bolts. The two mounting plates 20 are respectively used to fix the mold base 2 with the telescopic end of the press and the operating table. The heat insulation plate 21 is used to prevent heat from being transferred to the mounting plate 20 to cause energy waste and overheating damage to the press. The heating plate 22 is used to heat the mold to quickly form the inductor core. The two fixing plates 23 are respectively used to fix the upper mold 3 and the lower mold 4.

[0028] It also includes a pair of rods 42 and a pair of cylinders 32. The bottom of the cylinder 32 is fixedly connected to the top of the bottom fixing plate 23, the top of the rod 42 is fixedly connected to the bottom of the top heating plate 22, and the bottom of the rod 42 passes through the top fixing plate 23 and is plugged into the cylinder 32. When the upper mold 3 moves down for hot pressing, the bottom of the rod 42 is inserted into the cylinder 32 to limit the upper mold 3 and the lower mold 4 to prevent deviation, thereby further ensuring the stability of hot pressing.
