Description

Technical Field

[0001] This utility model belongs to the field of magnetic core technology, specifically relating to an automatic magnetic core feeding and pressing machine. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. Magnetic cores are fundamental components of electronic devices and come in a variety of shapes and structures. They are typically formed by pressing with a mold. In the manufacturing process of pressed powder magnetic cores, granulated powder containing soft magnetic powder and insulating binder material is compressed into a shaped form.

[0003] The existing magnetic cores are inconvenient to feed and remove during compression molding, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding and pressing machine for magnetic cores. It has a simple structure and automatically feeds the material when pressing magnetic cores. The material is also leveled by shaking at the bottom, which speeds up the work and is highly practical and suitable for widespread application.

[0005] This utility model provides the following technical solution: an automatic magnetic core feeding and pressing machine, including a base plate, a fixed frame erected on the base plate, a cylinder fixedly mounted in the middle of the truss at the top of the fixed frame, the output end of the cylinder facing vertically downward and fixedly mounted on an installation plate, a support column fixedly mounted on the base plate corresponding to the installation plate, an upper mold fixedly mounted at the lower end of the installation plate, and a lower mold fixedly mounted at the upper end of the support column corresponding to the upper mold.

[0006] The two side walls of the fixed frame are fixedly provided with symmetrical hoppers above the mounting plate. The hoppers are provided with a material outlet with an opening and closing mechanism. A material supply pipe is connected below the material outlet. The lower end of the material supply pipe is fixedly connected to the upper two sides of the lower mold through an inclined spoon.

[0007] A lifting base is placed inside the lower mold. Electric telescopic rods are fixed on both sides of the support column. A lifting ring is sleeved on the support column. The output end of the electric telescopic rod is fixedly connected to the lifting ring. A circular array of sliding rods is fixedly provided on the upper surface of the lifting ring. The sliding rods pass through the bottom of the lower mold and are fixedly connected to the lifting base.

[0008] Preferably, the bottom of the fixing frame is provided with mutually symmetrical inclined surfaces. The bottom of the fixing frame is formed by the inclined surfaces to create a shape that is high on the front and back sides and low at the center line. The bottom of the fixing frame is provided with an inclined groove at the center line. The inclined groove is lower on the side closer to the mounting plate, and the material discharge port is located at the lowest point of the inclined groove.

[0009] Preferably, the material outlet has a through oblique cut on the side near the mounting plate, and an oblique cutting plate is provided through the oblique cut. The oblique cutting plate obliquely cuts off the material outlet. A sliding horizontal plate is fixedly provided on the oblique cutting plate above the mounting plate and parallel to it. A support plate is fixedly provided on the hopper above the sliding horizontal plate. A support spring is fixedly provided on the lower surface of the support plate. The lower end of the support spring is slidably connected to the sliding horizontal plate.

[0010] Preferably, the shape of the lifting base matches the bottom shape of the lower mold, and the sidewalls are tightly connected to the lower mold.

[0011] The beneficial effects of this utility model are: simple structure, automatic feeding during the pressing production of magnetic cores via the movement of the upper mold, and smoothing of the raw material through bottom shaking, thus accelerating work efficiency and making it highly practical, as detailed below:

[0012] (1) This utility model is equipped with a hopper. The raw material is placed in the hopper. Due to the inclined bottom mechanism, the raw material can be gathered at the discharge port. When the magnetic core is pressed and the mounting plate rises, it contacts the sliding horizontal plate and lifts it up. During the process of the sliding horizontal plate rising, since it is inclinedly connected to the discharge port, the sliding horizontal plate slides towards the mounting plate, which drives the oblique cutting plate to cut off the discharge port part and pull it out. The raw material enters the feeding pipe from the discharge port and is discharged into the lower mold from the oblique spoon. Within a specified time, the mounting plate moves downward, the support spring pushes the sliding horizontal plate to reset, and the oblique cutting plate cuts off the discharge port again to realize automatic feeding.

[0013] (2) This utility model is equipped with a lifting base. After the magnetic core is pressed, the electric telescopic rod operates to push the lifting base up and push out the magnetic core, making it easy to remove the magnetic core. When the raw material at the slanted spoon enters the lower mold, the electric telescopic rod performs a high-frequency reciprocating motion on the lifting base to shake the raw material accumulated in the lower mold and move it to other parts. The raw material injected into the lower mold is shaken flat to facilitate the next pressing, thereby improving work efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] See Figure 1-2 An automatic magnetic core feeding and pressing machine includes a base plate 1, a fixed frame 2 erected on the base plate 1, a cylinder 3 fixedly mounted in the middle of the truss at the top of the fixed frame 2, the output end of the cylinder 3 facing vertically downward and fixedly mounted on a mounting plate 4, a support column 6 fixedly mounted on the base plate 1 corresponding to the mounting plate 4, an upper mold 5 fixedly mounted at the lower end of the mounting plate 4, the upper mold 5 is driven to press down by the cylinder 3, and a lower mold 7 is fixedly mounted at the upper end of the support column 6 corresponding to the upper mold 5, and the magnetic core is formed by pressing the upper mold 5 and the lower mold 7 together.

[0024] See Figure 1-2 The fixed frame 2 has symmetrical hoppers 11 fixed on both sides above the mounting plate 4. The hoppers 11 hold raw materials. The hoppers 11 have discharge ports 17 with opening and closing mechanisms. The discharge ports 17 are connected to the feed pipe 12. The lower end of the feed pipe 12 is fixedly connected to the upper two sides of the lower mold 7 through the inclined spoon 13. The raw materials slide into the lower mold 7 from the inclined spoon 13. The bottom of the fixed frame 2 has symmetrical inclined surfaces 14. The bottom of the fixed frame 2 is high on the front and back sides and low at the center line through the inclined surfaces 14, so that the raw materials inside can be gathered at the center line. The base of this shape can bear more raw materials. The bottom of the fixed frame 2 is provided with an inclined groove 15 at the center line. The inclined groove 15 is lower on the side closer to the mounting plate 4. The discharge port 17 is located at the lowest point of the inclined groove 15, so that the raw materials at the center line can be gathered at the discharge port 17. This structure can prevent the feeding mechanism from affecting the movement of the upper mold 5.

[0025] See Figure 2-3 The material outlet 17 has a through oblique cut 18 on the side near the mounting plate 4. An oblique cutting plate 19 is inserted through the oblique cut 18. The oblique cutting plate 19 obliquely cuts off the material outlet 17. A sliding horizontal plate 20 is fixedly installed on the oblique cutting plate 19 above the mounting plate 4 and parallel to it. When the mounting plate 4 rises, it contacts the sliding horizontal plate 20 and lifts it up, so that the oblique cutting plate 19 partially pulls out the material outlet 17, and the raw material can leak down. A support plate 21 is fixedly installed on the hopper 11 above the sliding horizontal plate 20. A support spring 22 is fixedly installed on the lower surface of the support plate 21. The lower end of the support spring 22 is slidably connected to the sliding horizontal plate 20. The support spring 22 pushes the sliding horizontal plate 20 to reset, and the oblique cutting plate 19 cuts off the material outlet 17 again.

[0026] See Figure 2 A lifting base 16 is placed inside the lower mold 7. The shape of the lifting base 16 matches the bottom shape of the lower mold 7, and its sidewalls are tightly connected to the lower mold 7 to prevent the raw material from leaking out of the gaps. Electric telescopic rods 8 are fixed on both sides of the support column 6. A lifting ring 9 is fitted on the support column 6. The output end of the electric telescopic rod 8 is fixedly connected to the lifting ring 9. The electric telescopic rod 8 pushes the lifting ring 9 up and down. A circular array of sliding rods 10 is fixedly provided on the upper surface of the lifting ring 9. The sliding rods 10 pass through the bottom of the lower mold 7 and are fixedly connected to the lifting base 16. The sliding rods 10 lift the lifting base 16, and the magnetic core is pushed out through the lifting base 16. When the electric telescopic rod 8 reciprocates at a high frequency, the lifting base 16 shakes the raw material in the lower mold 7, causing it to move to other parts.

[0027] This utility model of an automatic magnetic core feeding and pressing machine has a simple structure. When pressing magnetic cores, it automatically feeds materials by moving the upper mold and smooths the raw materials by shaking the bottom, which speeds up the work efficiency, is highly practical, and is suitable for promotion.

[0028] For specific usage, please refer to... Figure 1-3 The raw material is placed in the hopper. Due to the inclined bottom mechanism, the raw material can be gathered at the discharge port. After the magnetic core is pressed, when the mounting plate rises, it contacts the sliding horizontal plate and lifts it up. During the lifting process of the sliding horizontal plate, because it is inclinedly connected to the discharge port, the sliding horizontal plate slides towards the mounting plate, which drives the inclined cutting plate to cut off the discharge port and pull out. The raw material enters the feeding pipe from the discharge port and is discharged into the lower mold from the inclined spoon. Within a specified time, the mounting plate moves downward, the support spring pushes the sliding horizontal plate to reset, and the inclined cutting plate cuts off the discharge port again, stopping the feeding.

[0029] See Figure 2 After the magnetic core is pressed, the electric telescopic rod operates, pushing the lifting base upward to push out the magnetic core and remove it. When the raw material at the slanted spoon enters the lower mold, the electric telescopic rod performs a high-frequency reciprocating motion on the lifting base, shaking the raw material accumulated in the lower mold and moving it to other parts. The raw material injected into the lower mold is shaken flat for the next pressing.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
