Description

Technical Field

[0001] This utility model belongs to the field of magnet production technology, specifically, it relates to a mold for a permanent magnet ferrite magnet tile-shaped product. Background Technology

[0002] In modern industrial production, permanent ferrite magnet tile-shaped products have wide and important applications in many fields such as motors, electronic equipment, and automotive parts due to their unique magnetic properties and structural characteristics. With the rapid development and technological progress of these application fields, increasingly higher requirements are being placed on the quality, production efficiency, and cost control of permanent ferrite magnet tile-shaped products.

[0003] In existing technologies, ejector pin structures are typically installed inside the lower mold. After the permanent magnet ferrite magnet is formed, the ejector pin structure pushes out the formed permanent magnet ferrite magnet. However, when the ejector pin pushes out the formed product, uneven ejection force can easily cause quality problems such as cracks and deformation in the tile-shaped magnet, which will seriously affect the product's pass rate and performance stability. Secondly, during the maintenance of the mold, after a long period of use, it may be difficult to maintain the mandrel. As a result, friction and wear with the magnetic material and the adhesion of magnetic powder can easily lead to a decrease in dimensional accuracy and a deterioration in surface quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a permanent magnet ferrite magnet tile-shaped product mold, which aims to solve the quality problems such as cracks and deformation of the tile-shaped magnets caused by uneven force during ejection when the ejector pin is used to eject the molded product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mold for a permanent ferrite magnet tile-shaped product includes a lower mold base, a lower mold, a pressing component for forming the tile-shaped magnet, and a connecting component for demolding the formed tile-shaped magnet. The lower mold is fixed inside the lower mold base, and a cavity is formed inside the lower mold. A closing groove is formed on the outer wall of the lower mold, and the cavity communicates with the closing groove. A positioning groove is formed on the lower mold base, and the positioning groove communicates with the closing groove. A core rod is attached to the lower mold through the cavity and the closing groove. The core rod is attached to the lower mold base through the positioning groove. The pressing component is located directly above the lower mold base. The connecting component is disposed between the pressing component and the core rod. A side plate is fixedly connected to the outer wall of the core rod, and the side plate is attached to the lower mold through the cavity.

[0008] Preferably, the connecting assembly includes a base block fixedly connected to the mandrel, a sleeve plate fixedly connected to the top of the base block, a lifting block slidably connected inside the sleeve plate, a connecting rod fixedly connected to the top of the lifting block, a spring fixedly connected to the bottom of the lifting block, and the bottom of the spring fixedly connected to the inner bottom wall of the sleeve plate, so as to facilitate the pressing assembly to drive the mandrel to move upward or downward.

[0009] Preferably, a guide rod is fixedly connected to the bottom of the base block, and a guide hole is provided in the lower mold base through the positioning groove. The guide rod is slidably connected to the lower mold base through the guide hole to increase the accuracy of the mandrel movement.

[0010] Preferably, a limiting block is fixedly connected to the outer wall of the mandrel, and the limiting block fits into the lower mold through a sealing groove to seal both sides of the lower mold.

[0011] Preferably, the pressing assembly includes a hydraulic rod, the end of which is fixedly connected to an upper mold base, the connecting rod is fixedly connected to the upper mold base, and a pressing mold is fixedly connected to the bottom of the upper mold base to apply pressure to the magnetic material.

[0012] Preferably, a base is fixedly connected to the bottom of the lower mold base, and an outer frame is fixedly connected to one side of the top of the base. The hydraulic rod is fixed to the top of the hydraulic rod, which facilitates the installation of the pressing assembly directly above the lower mold base.

[0013] In summary, the technical effects and advantages of this utility model are as follows: This permanent magnet ferrite magnet tile-shaped product mold applies pressure to the magnetic raw material inside the cavity through the action of the pressing component. Through the cooperation of the core rod and the side plate, the magnetic raw material is shaped into a tile. Then, through the action of the connecting component, when the pressing component moves upward, the core rod and the side plate move upward accordingly, thereby moving the shaped tile magnet to separate from the lower mold, and then unloading the shaped tile magnet. At the same time, it is convenient for the maintenance of the core rod.

[0014] The combination of the base block, lifting block, sleeve plate, connecting rod and spring facilitates the downward pressing component to move the mandrel up and down for adjustment. The combination of the guide rod and guide hole increases the accuracy of the mandrel movement, thereby extruding the magnetic raw material and unloading the formed magnet.

To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0024] Reference Figure 1-4A mold for a permanent ferrite magnet tile-shaped product includes a lower mold base 1, a lower mold 2, a pressing component 8 for forming the tile-shaped magnet, and a connecting component 9 for demolding the formed tile-shaped magnet. The lower mold 2 is located at the internal center of the lower mold base 1 and is fixed inside the lower mold base 1. The lower mold 2 has a cavity 3 inside and a closed groove 4 on its outer side wall. There are two closed grooves 4, which are symmetrically distributed around the central axis of the lower mold 2. The cavity 3 is connected to the closed groove 4. The lower mold base 1 has a positioning groove 5. The number of closed grooves 4 and positioning grooves 5 are equal and correspond one-to-one. The positioning grooves 5 are connected to the closed grooves 4. A core rod 6 is attached to the lower mold 2 through the cavity 3 and the closed groove 4. The core rod 6 is adapted to the cavity 3 and is connected to the cavity 3 through the positioning groove 4. The slot 5 fits into the lower mold base 1. The pressing component 8 is located directly above the lower mold base 1. The connecting component 9 is located between the pressing component 8 and the core rod 6. There are two sets of connecting components 9, which are symmetrically distributed around the central axis of the core rod 6. The outer side wall of the core rod 6 is fixedly connected to a side plate 10. There are two side plates 10, which are symmetrically distributed around the central axis of the core rod 6. The side plates 10 fit into the lower mold 2 through the cavity 3. After the magnetic material is put into the cavity 3, the pressing component 8 extrudes the magnetic material inside the cavity 3 to form it. During the height adjustment of the pressing component 8, the core rod 6 and the side plate 10 are adjusted accordingly through the action of the connecting component 9, thereby moving the formed tile-shaped magnet to separate from the lower mold 2, which facilitates the unloading of the tile-shaped magnet.

[0025] Reference Figure 1-4 The connecting component 9 includes a base block 91 fixedly connected to the core rod 6. A sleeve plate 93 is fixedly connected to the top of the base block 91. A lifting block 92 is slidably connected inside the sleeve plate 93. The outer circumference of the lifting block 92 is equal to the inner circumference of the sleeve plate 93. A connecting rod 94 is fixedly connected to the top of the lifting block 92. A spring 95 is fixedly connected to the bottom of the lifting block 92. The spring 95 is located between the sleeve plate 93 and the lifting block 92. The bottom of the spring 95 is fixedly connected to the inner bottom wall of the sleeve plate 93. The pressing component 8 drives the connecting rod 94 to move. When the connecting rod 94 moves downward, the lifting block 92 compresses and deforms the spring 95. During the upward movement of the connecting rod 94, the core rod 6 moves and adjusts accordingly under the action of the lifting block 92, the sleeve plate 93, and the spring 95.

[0026] Reference Figure 2 and Figure 4 The bottom of the base block 91 is fixedly connected to a guide rod 96. The lower mold base 1 has a guide hole 97 through the positioning groove 5. The outer circumference of the guide rod 96 is equal to the inner circumference of the guide hole 97. The guide rod 96 is slidably connected to the lower mold base 1 through the guide hole 97. The guide rod 96 and the guide hole 97 increase the accuracy of the mandrel 6 moving up and down.

[0027] Reference Figure 2 and Figure 4 The outer wall of the mandrel 6 is fixedly connected to a limiting block 7. The number of limiting blocks 7 and the number of closing grooves 4 are equal and correspond one-to-one. The limiting block 7 fits into the lower mold 2 through the closing groove 4, and the limiting block 7 closes the two sides of the lower mold 2.

[0028] Reference Figure 1 and Figure 3 The pressing assembly 8 includes a hydraulic rod 81, with an upper mold base 82 fixedly connected to the end of the piston rod of the hydraulic rod 81. A connecting rod 94 is fixedly connected to the upper mold base 82, and a pressing die 83 is fixedly connected to the bottom of the upper mold base 82. After the hydraulic rod 81 is in operation, the upper mold base 82 drives the pressing die 83 to move downward, pressing the magnetic material into shape.

[0029] Reference Figure 1 The bottom of the lower mold base 1 is fixedly connected to the base 11. The lower mold base 1 is fixed at the top center of the base 11. The top side of the base 11 is fixedly connected to the outer frame 12. The hydraulic rod 81 is fixed at the top of the hydraulic rod 81. The outer frame 12 is located on the top left side of the base 11. The outer frame 12 makes the pressing component 8 stable directly above the lower mold base 1.

[0030] Working principle: First, the magnetic material is placed in the cavity 3 inside the lower mold 2. The hydraulic rod 81 operates, and the upper mold base 82 drives the pressing mold 83 to move downward. After the upper mold base 82 moves to fit with the lower mold 2, the magnetic material is pressed into shape under the action of the pressing mold 83, the side plate 10 and the core rod 6 to form a tile-shaped magnet. While the upper mold base 82 moves downward, it drives the connecting rod 94 to move downward. The lifting block 92 moves downward and squeezes the spring 95. The spring 95 is compressed and deformed. After the tile-shaped magnet is formed, the upper mold base 82 moves upward. After the pressing mold 83 moves to separate from the cavity 3, the core rod 6 moves upward under the action of the connecting component 9. The limiting block 7 and the side plate 10 move upward, and the formed tile-shaped magnet is removed from the inside of the lower mold 2. The guide rod 96 and the guide hole 97 increase the accuracy of the up and down movement of the core rod 6, so as to facilitate the removal of the formed tile-shaped magnet from the inside of the lower mold 2.
