Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic industry technology, specifically to an alignment mechanism for a soft magnet core forming mold. Background Technology
[0002] In the electronics industry, soft magnetic cores are a crucial component of many electronic devices, and their performance and quality significantly impact the overall performance of electronic equipment. With the rapid development of electronic technology, the demand for soft magnetic cores is increasing daily, simultaneously placing higher requirements on their precision, consistency, and production efficiency. Soft magnetic core molding technology, as a key link in the production process, directly determines the final quality of the core through its technical level and process stability. Therefore, continuously improving and perfecting soft magnetic core molding technology to enhance production efficiency and product quality has become an important research direction in the field of electronic materials manufacturing.
[0003] In existing soft magnet core molding technologies, problems exist in mold alignment and closing processes. Traditional molding dies often lack effective guiding and positioning mechanisms during alignment, leading to misalignment between the upper and lower molds during mold closing. This makes it difficult to guarantee the dimensional accuracy of the molded core, resulting in poor product consistency. Furthermore, the application of closing force lacks synchronous and uniform control, easily causing uneven stress on the mold, which not only affects the molding quality of the core but may also shorten the mold's lifespan. Utility Model Content
[0004] The purpose of this invention is to provide an alignment mechanism for a soft magnetic core forming mold, so as to solve the problem mentioned in the background art that traditional soft magnetic core forming molds often lack an effective guiding and positioning mechanism during alignment.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The alignment mechanism of the soft magnet core forming mold includes a lower mold and an upper mold for producing soft magnet cores. The lower mold has side seats symmetrically arranged on both sides, and a support base is installed at the bottom of the side seats.
[0007] The lower mold has symmetrical alignment guide rods on both sides of its top, and the upper mold is slidably fitted with the alignment guide rods. The upper mold has symmetrical end seats on both sides.
[0008] Each set of side seats is equipped with a support frame on its top, and two sets of support frames are equipped with synchronously operating alignment and mold-closing hydraulic cylinders. The piston rods of the two sets of alignment and mold-closing hydraulic cylinders are respectively connected to the top of the end seats on both sides.
[0009] Preferably, the top surface of the lower mold and the bottom surface of the upper mold are provided with soft magnet core forming grooves of the same diameter, which can provide precise and consistent cavity space for the forming of soft magnet cores, ensuring that the formed cores meet the design requirements in terms of size and shape, effectively improving the precision and consistency of the products, and meeting the high standard requirements of electronic devices for soft magnet cores.
[0010] Preferably, the top surface of the upper mold is equipped with a grouting pipe that communicates with the mold groove, providing a convenient and accurate channel for the magnetic core material to enter the mold groove smoothly. This ensures that the material can be filled into the molding space evenly and fully, avoiding problems such as incomplete filling or air bubbles, and helps to improve the molding quality of the magnetic core.
[0011] Preferably, a limiting seat is installed on the side of each set of side seats near the lower mold. The bottom sides of the lower mold are connected to the limiting seat by fixing bolts, which can firmly fix the position of the lower mold and prevent it from shifting or shaking during the mold operation. This enhances the overall stability and reliability of the mold and provides a guarantee for the stable molding of the magnetic core.
[0012] Preferably, an ejector cylinder is installed at the center of the top surface of the support base, which provides a power source for the demolding operation after the magnetic core is formed. It is a key component for realizing automated demolding, which helps to improve production efficiency and reduce manual intervention.
[0013] Preferably, the piston rod of the ejector cylinder is coaxially connected to an ejector rod at the top, so that the ejector rod can move stably and linearly under the drive of the ejector cylinder, thereby accurately ejecting the molded magnetic core from the mold groove and ensuring the smoothness and reliability of the demolding process.
[0014] Preferably, the bottom surface of the lower mold has an ejection hole at the center that matches the diameter of the ejector rod and is interference-fitted, ensuring a precise fit between the ejector rod and the mold cavity. This allows the magnetic core to be effectively ejected during demolding, while avoiding jamming or incomplete ejection during the ejection process, further improving demolding efficiency and the yield of the magnetic core.
[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: In the alignment mechanism of this soft magnetic core forming mold, by setting up a lower mold and an upper mold for producing soft magnetic cores, symmetrical side seats and support bases on both sides of the lower mold, a stable basic support structure is provided for the mold as a whole, ensuring the stability of the mold during operation. The alignment guide rods symmetrically arranged on both sides of the top of the lower mold slide in cooperation with the end seats on both sides of the upper mold, enabling the upper mold to maintain precise alignment during up and down movement, ensuring accurate mold closing between the upper and lower molds, and providing a guarantee for the precise forming of the soft magnetic core. The synchronously operating alignment and mold closing hydraulic cylinder installed on the top support frame of the side seats has its piston rod connected to the top of the end seats. Through the synchronous operation of the hydraulic cylinder, a stable and uniform mold closing force can be applied, allowing the upper mold to smoothly close with the lower mold, further improving the accuracy and stability of mold closing, which is beneficial to the high-quality forming of the soft magnetic core.

[0027] Alignment mechanism of soft magnet core forming mold, such as Figures 1-3 As shown, the mold includes a lower mold 10 and an upper mold 20 for producing soft magnetic cores. The lower mold 10 has symmetrically arranged side seats 30 on both sides, and a support base 40 is installed at the bottom of each side seat 30. Alignment guide rods 11 are symmetrically arranged on both sides of the top of the lower mold 10, and the upper mold 20 slides in conjunction with the alignment guide rods 11. End seats 21 are symmetrically arranged on both sides of the upper mold 20. A support frame 31 is installed on the top of each set of side seats 30, and two sets of support frames 31 are equipped with synchronously operating alignment and mold-closing hydraulic cylinders 50. The piston rods 51 of the two sets of alignment and mold-closing hydraulic cylinders 50 are respectively connected to the top of the end seats 21 on both sides. By setting up the lower mold 10 and upper mold 20 for producing soft magnetic cores, the symmetrical side seats 30 on both sides of the lower mold 10, and the support base 40, a stable basic support structure is provided for the entire mold, ensuring the stability of the mold during operation. The symmetrically arranged alignment guide rods 11 on both sides of the top of the lower mold 10 slide in cooperation with the end seats 21 on both sides of the upper mold 20, enabling the upper mold 20 to maintain precise alignment during its up-and-down movement. This ensures accurate mold closing between the upper mold 20 and the lower mold 10, guaranteeing the precise molding of the soft magnetic core. The synchronously operating alignment and mold closing hydraulic cylinder 50, mounted on the top support frame 31 of the side seat 30, has its piston rod 51 connected to the top of the end seat 21. Through the synchronous operation of the hydraulic cylinder 50, a stable and uniform mold closing force can be applied, allowing the upper mold 20 to smoothly close with the lower mold 10, further improving the accuracy and stability of mold closing and contributing to the high-quality molding of the soft magnetic core.
[0028] Furthermore, the top surface of the lower mold 10 and the bottom surface of the upper mold 20 are provided with soft magnet core forming grooves 12 of the same diameter, which provide a precise cavity for forming the soft magnet core and ensure that the dimensions of the formed soft magnet core meet the requirements.
[0029] Specifically, the top surface of the upper mold 20 is equipped with a grouting pipe 22 that is connected to the mold groove 12, which facilitates the injection of the magnetic core material into the mold groove 12, ensuring that the material can be accurately filled into the molding space and providing a material input channel for magnetic core molding.
[0030] Each set of side seats 30 has a limiting seat 32 installed on the side closest to the lower mold 10. The bottom sides of the lower mold 10 are connected to the limiting seat 32 by fixing bolts, which can further fix the position of the lower mold 10, prevent the lower mold 10 from shifting during operation, ensure the overall stability of the mold, and thus ensure the quality of magnetic core forming.
[0031] In addition, an ejector cylinder 41 is installed at the center of the top surface of the support base 40. An ejector rod 42 is coaxially connected to the top of the piston rod of the ejector cylinder 41. An ejector hole with an interference fit and matching diameter size to the ejector rod 42 is opened at the center of the bottom surface of the mold groove 12 of the lower mold 10. After the magnetic core is formed, the ejector cylinder 41 works, and the ejector rod 42 can eject the formed soft magnetic core from the mold groove 12 through the ejector hole, which facilitates the demolding of the magnetic core and improves production efficiency.
[0032] The working principle of the alignment mechanism of this soft magnetic core forming mold:
[0033] First, the alignment and mold-closing hydraulic cylinder 50, which works synchronously on the support frame 31, is activated. Its piston rod 51 retracts, driving the end seats 21 on both sides of the upper mold 20, so that the upper mold 20 moves upward along the alignment guide rods 11 on both sides of the top of the lower mold 10, opening the mold. Then, through the grouting pipe 22 at the center of the top surface of the upper mold 20, the soft magnet core material is injected into the soft magnet core forming mold groove 12 with the same center diameter as the top surface of the lower mold 10 and the bottom surface of the upper mold 20.
[0034] Then, the alignment and mold closing hydraulic cylinder 50 is activated again, the piston rod 51 extends, and pushes the upper mold 20 to move downward along the alignment guide rod 11, so as to achieve accurate mold closing between the upper mold 20 and the lower mold 10; after the magnetic core is formed in the mold groove 12, the piston rod 51 of the alignment and mold closing hydraulic cylinder 50 retracts and opens the mold again.
[0035] Finally, the ejector cylinder 41 at the center of the top surface of the support base 40 is activated. Its piston rod drives the ejector rod 42 to move upward and eject the formed soft magnet core from the mold groove 12 through the ejector hole at the center of the bottom surface of the lower mold 10, thus completing the demolding and removing the magnet core.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
