Description

Technical Field

[0001] This utility model relates to the field of inductor forming, and in particular to an inductor forming device. Background Technology

[0002] In the field of inductor powder compression molding, traditional equipment has significant limitations. Fixed-volume molding chambers are ill-suited for producing inductors of varying specifications, leading to frequent mold changes and resulting in low efficiency and high costs. Furthermore, powder overflow and waste are common during the feeding process; existing powder feeding mechanisms struggle to effectively recover overflow and ensure a tight seal with the mold, causing both material loss and impacting the cleanliness of the die-casting environment. In addition, poor clamping force control and insufficient mold stability also restrict product quality and production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an inductor forming device to solve the problems existing in the prior art.

[0004] The technical solution of this utility model is: an inductor forming equipment for extruding powder into an inductor, comprising an upper mold assembly, a middle mold assembly, and a lower mold assembly arranged sequentially from top to bottom along a vertical direction.

[0005] The upper mold assembly includes an upper template, which is connected to an upper mold driver. An upper pressure head is fixed to one end of the upper template near the middle mold assembly.

[0006] The middle mold assembly includes a fixed middle mold plate, and the middle mold plate has a material groove that runs vertically through it, corresponding to the upper mold plate. The upper pressure head can be inserted into the top of the material groove under the drive of the upper mold driver.

[0007] The lower mold assembly includes a lower mold plate, which is connected to a lower mold driver. A lower pressing head is fixed at one end of the lower mold plate near the middle mold plate. The lower pressing head can be inserted into the bottom of the material groove under the drive of the lower mold driver.

[0008] The material trough and the pressing head cooperate to form a chamber for pouring powder, and the depth of the pressing head entering the material trough corresponds synchronously to the volume of the chamber.

[0009] Preferably, the middle template is provided with a powder feeding mechanism, which includes a powder feeding ring. The powder feeding ring is circumferentially closed and its top end is connected to a powder supply device. Under the horizontal drive of the powder feeding driver, the powder feeding ring has a first station and a second station, which respectively connect and disconnect the bottom end from the material trough.

[0010] Preferably, the powder feeding mechanism includes a powder feeding base, on which a powder compactor is provided. The actuating end of the powder compactor abuts against the top end of the powder feeding ring, so that the bottom end of the powder feeding ring is tightly abutted against the top end of the middle template.

[0011] Preferably, the powder compactor includes a compaction rod, the middle part of which is hinged to the powder feeding base via a connecting rod. One end of the compaction rod rises around the hinged end in the middle under the drive of the compaction driver, and the other end serves as the execution end and simultaneously presses down on the powder feeding ring.

[0012] Preferably, the actuating end is connected to a powder feeding spring plate, and the bottom end of the powder feeding spring plate abuts against the powder feeding ring.

[0013] Preferably, a guide post is provided that penetrates the upper template, the middle template and the lower template.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) By precisely controlling the depth of the pressure head into the material groove, this application can flexibly change the volume of the molding chamber in real time. It can adapt to the molding of different sizes and specifications of inductors without changing the mold, which significantly improves production flexibility and efficiency and reduces mold change costs.

[0016] (2) The powder feeding mechanism, through the horizontally moving closed powder feeding ring, not only achieves accurate powder feeding, but also when it moves to the second station after the first station completes the feeding, its bottom end, which slides close to the template, can efficiently scrape back and recover all the powder overflowing from the trough, realizing the closed-loop utilization of overflow and greatly reducing raw material loss.

[0024] The present invention will be further described in detail below with reference to specific embodiments:

[0025] like Figure 1 and Figure 2 As shown, an inductor forming device is used to extrude powder into an inductor, comprising an upper mold assembly 1, a middle mold assembly 2, and a lower mold assembly 3 arranged sequentially from top to bottom in a vertical direction.

[0026] The upper mold assembly 1 includes an upper template 11 connected to an upper mold driver 12. An upper pressure head 13 is fixed to one end of the upper template 11 near the middle mold assembly 2. The middle mold assembly 2 includes a fixed middle template 21 with a vertically extending material groove 22 corresponding to the upper template 11. The upper pressure head 13 can be inserted into the top of the material groove 22 under the drive of the upper mold driver 12. The lower mold assembly 3 includes a lower template 31 connected to a lower mold driver 32. A lower pressure head is fixed to one end of the lower template 31 near the middle template 21. The lower pressure head can be inserted into the bottom of the material groove 22 under the drive of the lower mold driver 32. At this time, the periphery of the material groove 22 and the top of the lower pressure head together form a chamber for pouring powder. The lower pressure head is moved up and down by the lower mold driver 32 to adjust the depth of the lower pressure head into the material groove 22, thereby changing the volume of the chamber and controlling the size of the material after powder molding. Guide posts 5 are provided through the upper template 11, the middle template 21 and the lower template 31. The guide posts 5 have steps and threads in the middle section and nuts are provided to match the threads. The steps and nuts abut against the upper and lower ends of the middle template 21 respectively, thereby fixing the position of the middle template 21.

[0027] A powder feeding mechanism 4 is provided on the middle template 21. For example... Figures 3-5As shown, the powder feeding mechanism 4 includes a powder feeding ring 41, which is circumferentially closed. Its top end has a pipe connecting to a powder supply device for supplying powder, while its bottom end is open and can fit tightly against the upper surface of the intermediate template 21. The powder feeding ring 41 is connected to a powder feeding driver 42, which drives the powder feeding ring 41 to extend and retract horizontally, giving it a first station and a second station. In the first station, the bottom end of the powder feeding ring 41 is connected to the material trough 22, and the powder supplied by the powder supply device falls into the material trough 22 through the pipe. When the powder feeding ring 41 enters the second station, it is positioned away from the material trough 22. During this process, the bottom end of the powder feeding ring 41 slides tightly against the intermediate template 21, causing any powder overflowing from the material trough 22 to be scraped away by the powder feeding ring 41 and used for the next material forming.

[0028] Specifically, the powder feeding mechanism 4 includes a powder feeding base 43, on which a powder compactor 44 is mounted. The powder feeding ring 41 is pressed tightly against the middle template 21 by the powder compactor 44. The actuating end of the powder compactor 44 abuts against the top of the powder feeding ring 41, allowing the bottom end of the powder feeding ring 41 to press tightly against the top of the middle template 21. The powder compactor 44 includes a pressing rod 441, the middle of which is hinged to the powder feeding base 43 via a connecting rod. One end of the pressing rod rises around the hinged end in the middle under the drive of the pressing driver 442, while the other end serves as the actuating end and simultaneously presses down on the powder feeding ring 41 under the action of leverage.

[0029] Furthermore, in order to make the force exerted by the clamping rod 441 on the powder feeding ring 41 more gentle, in a preferred embodiment of this application, a powder feeding spring plate 443 is installed at the actuating end of the clamping rod 441, and a spring is built into the powder feeding spring plate 443. When the clamping rod 441 applies clamping force, the spring is compressed, thereby easing the pressure of the clamping rod 441 on the powder feeding ring 41.

[0030] During work:

[0031] The pressing head extends into the bottom of the material trough 22 and the depth of entry is adjusted to meet the material forming requirements. After the powder feeding ring 41 enters the first station, the powder feeding device pours the powder into the material trough 22, and then the powder feeding ring 41 enters the second station and simultaneously scrapes away the overflowing powder.

[0032] The upper pressure head 13 descends to die-cast the powder in the material tank 22 into an inductor. The formed inductor is then ejected from the material tank 22 by the lower pressure head, completing the demolding of the inductor.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
