[0029] Refer to Figure 1, A die mechanism for inductor forming, comprising: a die base 100, an installation chamber 300, a protection area 150 and a separator 190, connected with a first die table 200 and a second die table 600 that can move relatively closer or farther away; the installation chamber 300 is arranged in the die base 100, and the installation chamber 300 is used for installing and positioning the coil 800; the first die table 200 and the second die table 600 are respectively located on both sides of the installation chamber 300; the protection area 150 is located outside the installation chamber 300, the protection area 150 is communicated with the installation chamber 300, and the protection area 150 is located on the side of the installation chamber 300 away from the first die table 200; the separator 190 is arranged in the installation chamber 300, the separator 190 is located between the installation chamber 300 and the protection area 150, and the separator 190 is used to prevent the first die table 200 from extending into the protection area 150 during movement. When forming operations need to be performed on the coil 800, the coil 800 can be first placed in the installation chamber 300 on the die base 100, and the pins 850 of the coil 800 can be extended into the protection area 150. After the coil 800 and its pins 850 are both properly placed, the first die table 200 and the second die table 600 can move relatively and perform a die closing and stamping operation. During the die closing process, the separator 190 will relatively block between the first die table 200 and the protection area 150. Therefore, the movement of the first die table 200 will hardly interfere with the pins 850 of the coil 800 in the protection area 150, effectively avoiding the problem of the pins 850 of the coil 800 being dented or bent due to impact force during the processing of the die, and then ensuring that the formed inductor coil 800 can work smoothly and avoiding the problem of short circuit during its operation.
[0030] In some embodiments, referring to Figure 2 , one end of the protection area 150 is connected to the installation chamber 300 from the side of the installation chamber 300 away from the first die table 200, and the separator 190 is located at the junction of the installation chamber 300 and the protection area 150 and is used to support the coil 800. When the coil 800 is placed in the installation chamber 300, it will be placed at the separator 190, and the coil 800 will be positioned by the separator 190, so that the pins 850 on the coil 800 can smoothly extend into the protection area 150. And, since the protection area 150 is located on the side of the installation chamber 300 away from the first die table 200, it can also effectively ensure that when the pins 850 extend into the protection area 150, their positional relationship is on the side away from the first die table 200, and then the effect of avoiding interference of the first die table 200 on the pins 850 can be smoothly achieved.
[0031] It can be envisioned that the separator 190 can be provided with structures for positioning the coil 800, such as clamping jaws, positioning bosses or clamping blocks, etc. The specific implementation manners can be adjusted according to actual needs and are not limited herein.
[0032] In some embodiments, referring to Figure 3 , the protection area 150 extends from one side of the spacer 190 to below the spacer 190. The first mold table 200 is located above the spacer 190 and can move closer to or away from the spacer 190; the spacer 190 can support the coil 800 on its top. The protection area 150 is located below the spacer 190 while the first mold table 200 is located above the spacer 190. Therefore, the spacer 190 can directly and effectively separate between the first mold table 200 and the protection area 150, thus effectively preventing the first mold table 200 from damaging the pins 850 in the protection area 150 when moving, and further ensuring that the formed coil 800 can have intact pins 850 and avoiding corresponding short - circuit problems.
[0033] It can be envisaged that the protection area 150 can also be directly opened inside the spacer 190, rather than only being arranged below the spacer 190, as long as it can achieve relative isolation between the first mold table 200 and the pins 850. The specific implementation manner can be adjusted according to actual needs and is not limited herein.
[0034] In some embodiments, referring to Figure 5 , the protection area 150 extends linearly downward from the bottom of the installation chamber 300. The linear extension of the protection area 150 can enable the pins 850 of the coil 800 to extend linearly downward toward the bottom of the installation chamber 300. Therefore, the pins 850 in the protection area 150 can be as far away as possible from the installation chamber 300 and the first mold table 200, thus effectively preventing the first mold table 200 from damaging the pins 850 when impacting the coil 800 body.
[0035] Specifically, the shape and size of the protection area 150 are both adapted to the pins 850 of the coil 800. The adapted protection area 150 can not only protect the pins 850, but also effectively achieve the shaping effect of the pins 850, thereby improving the forming accuracy of the finished product.
[0036] In some embodiments, referring to Figure 4 , the protection area 150 is located between the bottom wall of the installation chamber 300 and the spacer 190 and is flush with the bottom wall of the spacer 190. The protection area 150 can obtain the limiting and shaping effects of the bottom wall of the installation chamber 300 and the spacer 190. Therefore, the pins 850 can not only avoid being damaged by the first mold table 200, but also maintain the accuracy of their shape, thus effectively improving the quality of the finished product.
[0037] In some embodiments, referring to Figure 4, there is a gap 135 between the side of the spacer 190 and the inner wall of the installation chamber 300. The protection area 150 communicates with the gap 135. The widths of both the gap 135 and the protection area 150 are adapted to the pins 850 of the coil 800. The spacer 190 can be relatively positioned between itself and the installation chamber 300 through the gap 135, and the width adaptation also enables both the gap 135 and the protection area 150 to shape and protect the pins 850. Therefore, the pins 850 of the coil 800 can ensure their accurate insertion into the protection area 150 through the gap 135 and obtain the protection effect from the gap 135 and the protection area 150.
[0038] In some embodiments, referring to Figure 5 , the mold base 100 has a protection frame 700, and the installation chamber 300 is located within the protection frame 700. The protection frame 700 can not only effectively prevent external substances from entering the installation chamber 300 during the operation of the mold and interfering with the processing of the coil 800, but also block the materials within the installation chamber 300, thereby preventing substances such as powder generated during the processing and shaping of the coil 800 from splashing outside the installation chamber 300. Therefore, it can also effectively prevent the processing and shaping operation of the mold from polluting the external environment.
[0039] In some embodiments, referring to Figure 3 , the protection frame 700 has a support wall 750 located within the installation chamber 300. The support wall 750 is used to support the portion of the pin 850 outside the protection area 150. The support wall 750 can support and protect the portion of the pin 850 that does not extend into the protection area 150, so that when the coil 800 is impacted by the first mold table 200, the entire pin 850 can effectively obtain support and protection effects, thereby avoiding problems such as depression and bending of the pin 850.
[0040] In some embodiments, referring to Figure 2 , the protection area 150 bends and extends below the spacer 190, and the protection frame 700 is located at the end of the protection area 150 and is used to block the pins 850 of the coil 800. Since the protection area 150 is located below the spacer 190, the pins 850 can be supported and cradled on both sides by the installation chamber 300 and the spacer 190, effectively avoiding problems such as depression and bending. The pins 850 extend into the protection area 150 from one side of the spacer 190, while the protection frame 700 can block the pins 850 within the protection area 150 from the other side of the spacer 190, thereby effectively preventing the pins 850 from extending into the installation chamber 300 and further avoiding interference from the outside to the pins 850 during mold processing.
[0041] In the second aspect of the present utility model, an embodiment of a molding die is proposed, which includes the above-mentioned die mechanism for inductor molding. When the coil 800 needs to be molded, the coil 800 can be first placed in the installation chamber 300 on the die base 100, and the pins 850 of the coil 800 are extended into the protection area 150. After the coil 800 and its pins 850 are properly placed, the first die table 200 and the second die table 600 can move relative to each other and perform the die closing and stamping operation. During the die closing process, the isolation member 190 will relatively block between the first die table 200 and the protection area 150. Therefore, the movement of the first die table 200 will hardly interfere with the pins 850 of the coil 800 in the protection area 150, effectively avoiding the problem of indentation or bending of the pins 850 of the coil 800 caused by the impact force during the processing of the die, and further ensuring that the molded inductor coil 800 can work smoothly and avoiding the problem of short circuit during its operation.
[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0043] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the purpose of the present utility model within the knowledge scope of those of ordinary skill in the art.
