Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a high-frequency low-temperature magnetic core molding die. Background Technology

[0002] High-frequency low-temperature magnetic cores are magnetic material cores specifically designed to operate at high frequencies, and whose magnetic properties are minimally affected by temperature changes. High-frequency low-temperature magnetic cores must be formed using molding dies because the raw material for high-frequency low-temperature magnetic cores is ultrafine powder. Transforming loose magnetic powder into a high-strength solid magnetic core requires two key steps: die casting and high-temperature sintering.

[0003] However, the following defects still exist: after the existing magnetic core forming mold is die-cast, it is often difficult to remove the magnetic core because the magnetic core is closely attached to the mold. It is necessary to manually pry it up with tools. Using tools to pry it up can easily damage the surface of the mold or the formed magnetic core. In order to better address the above problems, promote the development of the industry's technical level, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-frequency low-temperature magnetic core forming mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-frequency low-temperature magnetic core forming mold includes a base and a housing. The base is fixed to the bottom of the housing by bolts. An upper mold assembly is provided in the upper space inside the housing. A lower mold is fixedly connected to the upper surface of the base. Multiple through holes are opened on the top of the base, and multiple mold cavities on the lower mold are connected to the through holes at corresponding positions on the bottom. An inclined block is movably connected to the inside of the base through a first guide assembly. Multiple push rods are fixedly connected to the upper surface of the inclined block, and the push rods are inserted into the through holes at corresponding positions and slidably connected to the through holes. Connecting frames are movably connected to the inner walls on both sides of the base through a second guide assembly. Rollers are movably connected to the connecting frames. One end of the connecting frame passes through the base and has a first insertion hole and a second insertion hole. A pin assembly for limiting the position of the connecting frame is provided on one outer wall of the base. A pusher assembly is provided on one side of the housing.

[0007] As a further embodiment of this utility model, the upper mold assembly includes a fixing frame, which is fixed to the inner wall of one side of the housing by bolts. An electric push rod is fixedly connected to the fixing frame. The extended end of the electric push rod passes through the fixing frame and is fixedly connected to the upper mold. The upper mold is in contact with the inner wall of the housing. The upper mold and the lower mold are vertically corresponding.

[0008] As a further embodiment of this utility model, the first guide component includes two trapezoidal blocks, which are welded to one side of the inclined block. Two trapezoidal grooves are formed on one side of the inner wall of the housing, and the trapezoidal blocks are slidably connected to the trapezoidal grooves at corresponding positions.

[0009] As a further embodiment of this utility model, the second guide component includes two T-shaped blocks, which are fixed to both sides of the connecting frame by bolts. T-shaped grooves are provided on both sides of the inner wall of the base, and the T-shaped blocks are slidably connected to the T-shaped grooves.

[0010] As a further embodiment of this utility model, the pin assembly includes a fixing plate, which is fixed to one side of the outer wall of the base by bolts. The fixing plate has a socket, and a plug rod is inserted into the socket. The plug rod is inserted into a second socket, and the first socket and the second socket are the same size.

[0011] As a further embodiment of this utility model, the pushing assembly includes an electric telescopic rod, which is fixed to one side of the outer wall of the housing by bolts. The extended end of the electric telescopic rod passes through the housing and is fixedly connected to a push plate, and the bottom of the push plate is in contact with the upper surface of the lower mold.

[0012] As a further embodiment of this utility model, a collection box is placed on the upper surface of the base, and the collection box is located on the side of the lower mold.

[0013] As a further embodiment of this utility model, a partition is fixedly connected inside the base, and a storage chamber is provided at the bottom of the partition. A connection port is opened at the bottom of the side of the shell, and a door panel is movably connected inside the connection port.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The mechanical transmission between the inclined block and the roller in this utility model converts the horizontal thrust into a vertical ejection force, causing the ejector rod to move along the through hole and move the die-cast workpiece out of the mold cavity of the lower mold. This avoids the need for manual prying with tools, which can easily damage the surface of the mold or the formed magnetic core, and improves the effectiveness of the device.

[0016] 2. In this utility model, the pin assembly fixes the position of the connecting frame. When the connecting frame drives the roller to move to the predetermined position, the pin is inserted into the first insertion hole of the connecting frame to prevent it from moving, thereby fixing the position of the ejector rod after the workpiece is ejected, and further ensuring the stability of the demolding process.

[0017] 3. This utility model is equipped with an upper mold assembly and a lower mold for use together, which supports synchronous die casting of multiple cavities and improves production efficiency. The first guide assembly and the second guide assembly are set to guide the inclined block and the connecting frame, reducing the risk of deflection.

[0018] 4. This utility model, through the setting of the pusher assembly, enables the pusher plate to push out the workpiece ejected from the lower mold. With the use of the collection box, the magnetic core can be collected, making it convenient for workers to perform centralized processing. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5A high-frequency low-temperature magnetic core forming mold includes a base 10 and a housing 1. The base 10 is fixed to the bottom of the housing 1 by bolts. An upper mold assembly is provided in the upper space inside the housing 1. The upper mold assembly includes a fixing frame 2, which is fixed to the inner wall of one side of the housing 1 by bolts. An electric push rod is fixed to the fixing frame 2 by bolts. The extended end of the electric push rod passes through the fixing frame 2 and is fixed to the upper mold 4 by bolts. The upper mold 4 is in contact with the inner wall of the housing 1. The upper mold 4 and the lower mold 5 are vertically aligned. The lower mold 5 is fixed to the upper surface of the base 10 by bolts. The raw material is placed into multiple cavities of the lower mold 5. The upper mold 4 is pushed downward by the electric push rod to close with the lower mold 5. Under the combined action of the upper mold 4 and the lower mold 5, the raw material is die-cast into a magnetic core.

[0027] The top of the base 10 has multiple through holes 13, and the multiple mold cavities on the lower mold 5 are connected to the through holes 13 at the corresponding positions on the bottom. The interior of the base 10 is slidably connected to the inclined block 20 through the first guide assembly. The first guide assembly includes two trapezoidal blocks 19, which are welded to one side of the inclined block 20. Two trapezoidal grooves 18 are opened on one side of the inner wall of the housing 1, and the trapezoidal blocks 19 are slidably connected to the trapezoidal grooves 18 at the corresponding positions. The first guide assembly can guide the inclined block 20.

[0028] Multiple push rods 21 are welded to the upper surface of the inclined block 20, and the push rods 21 are inserted into the corresponding through holes 13 and slidably connected to the through holes 13. The connecting frame 8 is slidably connected to the inner walls of both sides of the base 10 through the second guide assembly. The second guide assembly includes two T-shaped blocks 3, which are fixed to both sides of the connecting frame 8 by bolts. T-shaped grooves 6 are opened on both sides of the inner walls of the base 10, and the T-shaped blocks 3 are slidably connected to the T-shaped grooves 6. By setting the second guide assembly, the T-shaped blocks 3 can move along the T-shaped grooves 6, thereby guiding the connecting frame 8 and preventing the connecting frame 8 from tilting during the movement.

[0029] A roller 22 is rotatably connected to the connecting frame 8. One end of the connecting frame 8 passes through the base 10 and has a first insertion hole 7 and a second insertion hole 14. A pin assembly is provided on one side of the outer wall of the base 10 to limit the position of the connecting frame 8. The pin assembly includes a fixing plate, which is fixed to the outer wall of one side of the base 10 by bolts. An insertion port is provided on the fixing plate, and a rod 15 is inserted into the insertion port. The rod 15 is inserted into the second insertion hole 14. The first insertion hole 7 and the second insertion hole 14 are the same size. The operator pulls the rod 15 upward to move it out of the second insertion hole 14, pushes the connecting frame 8, and causes the roller 22 to move along the inclined surface at the bottom of the trapezoidal block 19. The trapezoidal block 19 is subjected to force and moves upward along the T-slot 6, thereby causing the top rod 21 to move upward along the through hole 13 and contact the workpiece, so that the formed workpiece is gradually moved out of the mold cavity of the lower mold 5.

[0030] A pusher assembly is provided on one side of the housing 1. The pusher assembly includes an electric telescopic rod 17. The electric telescopic rod 17 is fixed to the outer wall of one side of the housing 1 by bolts. The extended end of the electric telescopic rod 17 passes through the housing 1 and is fixed to a push plate 16 by bolts. The bottom of the push plate 16 is in contact with the upper surface of the lower mold 5. The extension of the electric telescopic rod 17 causes the push plate 16 to move, thereby pushing the ejected magnetic core.

[0031] A collection box 9 is placed on the upper surface of the base 10, and the collection box 9 is located on the side of the lower mold 5. The push plate 16 moves so that the ejected magnetic core is pushed into the collection box 9.

[0032] A partition 12 is fixed inside the base 10 by bolts. A storage chamber 11 is provided at the bottom of the partition 12. The storage chamber 11 is used to store tools and items. A connection port is provided at the bottom of the side of the housing 1. A door panel is rotatably connected to the connection port.

[0033] Working principle: When the magnetic core needs to be die-cast,

[0034] Die casting:

[0035] First, the raw material is placed into multiple cavities of the lower mold 5. Then, the electric push rod fixed on the fixed frame 2 is activated to push the upper mold 4 downward and close with the lower mold 5. Under the combined action of the upper mold 4 and the lower mold 5, the raw material is die-cast into a magnetic core.

[0036] Demolding preparation:

[0037] After die casting is completed, the upper mold 4 moves upward under the drive of the electric push rod and separates from the lower mold 5;

[0038] The worker pulls the insert rod 15 upwards, causing it to move out of the second insert hole 14, and pushes the connecting frame 8, causing the roller 22 to move along the inclined surface at the bottom of the trapezoidal block 19. The trapezoidal block 19 is subjected to force and moves upwards along the T-slot 6, thereby causing the ejector rod 21 to move upwards along the through hole 13 and contact the workpiece, so that the formed workpiece is gradually moved out of the mold cavity of the lower mold 5, and at this time the top of the ejector rod 21 and the upper surface of the lower mold 5 are on the same horizontal plane.

[0039] Then, the electric telescopic rod 17 is activated. The electric telescopic rod 17 extends, causing the push plate 16 to move, so that the ejected magnetic core is pushed into the collection box 9.

[0040] The pin assembly is used to fix the position of the connecting frame 8. When the connecting frame 8 drives the roller 22 to move to the predetermined position, the plug 15 is inserted into the first socket 7 of the connecting frame 8 to prevent it from moving.

[0041] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
