Description

Technical Field

[0001] This utility model relates to the field of industrial parts processing, specifically a pressing and forming device for manganese-zinc iron magnetic cores. Background Technology

[0002] With the rapid development of the electronics and information industry, manganese-zinc ferrite materials, as the core material for high-frequency magnetic cores, directly affect the performance and cost of electronic components due to the efficiency and precision of their pressing and molding processes. Traditional pressing and molding of manganese-zinc ferrite cores mainly relies on die pressing or dry pressing processes, which generally suffer from long production cycles, high material waste rates, and high equipment energy consumption. Especially in emerging fields such as 5G communication and new energy vehicles, the requirements for miniaturization and high stability of magnetic cores are constantly increasing, and traditional processes can no longer meet the needs of large-scale production. Therefore, developing efficient and energy-saving pressing and molding equipment has become an important direction for technological upgrading in the industry.

[0003] Currently, the pressing and molding equipment for manganese-zinc ferrite cores typically employs a horizontal structure, using mechanical transmission or a hydraulic system to drive the mold and compress the material. A typical device includes a storage silo, mold cavity, top-pressing mechanism, and heating components. Its core principle is to inject uniformly mixed powder into the mold cavity, achieve preliminary molding through unidirectional or bidirectional pressure, and then complete the curing process through sintering. However, this type of equipment suffers from complex structure and cumbersome operation procedures. Furthermore, uneven material distribution during transport can lead to variations in molding density, affecting product consistency. In addition, traditional equipment relies heavily on manual feeding, resulting in low automation and difficulty in adapting to the demands of intelligent production.

[0004] The workflow of existing compression molding equipment typically includes the following steps: mixing manganese-zinc ferrite powder with a binder, granulating and drying it for later use; mold filling: filling the mold cavity with powder by vibration or screw conveyor; pressure molding: using a hydraulic cylinder or robotic arm to drive the upper mold to press the powder, with a pressure range typically of 50-200 MPa; demolding and transfer: removing the blank from the mold cavity by ejector rod or pneumatic device and transferring it to a sintering furnace for subsequent processing.

[0005] Existing technologies generally use horizontal structures that rely on external power to transport powder, which consumes a lot of energy and easily generates dust pollution. They also have the problem of uneven forming density. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a pressing and molding device for manganese-zinc iron magnetic cores to solve the technical problems of low material feeding efficiency and unstable molding quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pressing and forming device for manganese-zinc iron magnetic cores, comprising a storage tank, a processing tank at one end of the storage tank, an installation bucket at the other end of the storage tank, a baffle at the end of the installation bucket away from the storage tank, a partition slidably disposed inside the installation bucket, a top rod at the end of the partition near the storage tank, the top rod extending into the storage tank, a pressing block connected to the end of the top rod inside the storage tank, a forming rod at the end of the pressing block near the processing tank, an inlet at the other end of the storage tank in conjunction with the forming rod, and a forming pipe in the processing tank in conjunction with the inlet;

[0008] By adopting the above technical solution, the material enters the forming pipe and is extruded and formed by the forming rod.

[0009] The present invention is further configured such that a pair of connecting rods are symmetrically arranged at one end of the installation bucket near the storage tank, and the connecting rods are connected to the storage tank.

[0010] By adopting the above technical solution, the installation bucket and the storage tank are connected by a connecting rod.

[0011] The present invention is further configured such that the inner wall of the processing tank is provided with a plurality of heating devices, and the end of the processing tank away from the storage tank is provided with a discharge limiting plate in conjunction with the forming pipe.

[0012] By adopting the above technical solution, the forming pipe is heated by a heating device, thereby ensuring the forming of the material.

[0013] The present invention is further configured such that connecting blocks are symmetrically arranged on the upper and lower sides of the partition, a transmission rod is provided through the baffle, one end of the transmission rod is provided through the baffle, and a control motor is provided on the other side of the baffle in conjunction with the transmission rod.

[0014] By adopting the above technical solution, the transmission rod is rotated by controlling the motor, thereby controlling the movement of the baffle and thus the movement of the forming rod.

[0015] The present invention is further provided with a friction pad around the outer periphery of the top pressure block.

[0016] By adopting the above technical solution, the friction pad ensures the movement of the top pressure block while maintaining the airtightness of the device.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model adopts a vertical structure design, allowing materials in the storage tank to fall naturally to the inlet by gravity, reducing manual feeding steps. The top pressure block, driven by the partition, compresses the material into the forming pipe, achieving continuous and stable pressing and forming through mechanical transmission, avoiding manual operation errors, and improving production efficiency and product consistency;

[0019] 2. This utility model uses a heating device on the inner wall of the groove to continuously heat the material in the forming pipe, ensuring that the material maintains its plasticity during the pressure process, promoting the solidification of the molecular structure, and improving the forming quality of the magnetic core.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A pressing and molding apparatus for manganese-zinc iron magnetic cores, such as Figure 1-3As shown, the system includes a storage tank 1, a processing tank 6 at one end of the storage tank 1, and an installation tank 2 at the other end of the storage tank 1. A baffle 8 is located at the end of the installation tank 2 away from the storage tank 1. A partition 9 is slidably disposed inside the installation tank 2. A top rod 12 is located at the end of the partition 9 near the storage tank 1, extending into the storage tank 1.

An inlet 14 is provided at the other end of the storage tank 1 in conjunction with the forming rod 13. A forming pipe 15 is provided inside the processing tank 6 in conjunction with the inlet 14. In actual use, the material is squeezed into the forming pipe 14 by the top rod 12 pressing against the inlet 14, thus forming the material.

[0027] A pair of connecting rods 4 are symmetrically arranged at one end of the installation bucket 2 near the storage tank 1. The connecting rods 4 are connected to the storage tank 1, and the installation bucket 2 and the storage tank 1 are connected by the connecting rods 4.

[0028] The inner wall of the processing tank 6 is provided with a number of heating devices 16.

The heating devices 16 heat the material in the forming pipe 14 to ensure the forming of the material.

[0029] The partition 9 is symmetrically provided with connecting blocks 10 on its upper and lower sides. A transmission rod 11 is provided through the baffle 8. One end of the transmission rod 11 is provided through the baffle 8. The other side of the baffle 8 is provided with a control motor 5 in conjunction with the transmission rod 11.
