Abstract

This invention relates to the field of magnetic tile technology, specifically to an arc-shaped magnetic tile forming mold, comprising a base plate, a column mounted on the base plate, and a top cover fitted onto the other end of the column. The column has an annular cavity, within which several sets of partitions are evenly distributed circumferentially. Adjacent partitions are spaced apart, forming a magnetic tile cavity. Each partition includes two spaced-apart side pressure heads, with a pressure cavity formed between the two side pressure heads. A secondary channel corresponding to the pressure cavity is provided within the column. In operation, the secondary channel introduces a medium into the pressure cavity, forcing the side pressure heads to press the magnetic tiles within the magnetic tile cavity. Through the annular cavity design, this invention allows several magnetic tiles to interfere with each other during simultaneous forming, ensuring uniform force on all tiles. After one forming process, the several magnetic tiles within the annular cavity can be used on a single motor, forming a magnetic tile set for the same motor to guarantee the motor's magnetic performance during operation.

Description

Technical Field

[0001] This invention relates to the field of magnetic tile technology, specifically to arc-shaped magnetic tile forming molds. Background Technology

[0002] Curved magnetic tile forming molds are specialized tools used to manufacture curved magnetic tiles. In modern industry, especially in the production of equipment such as motors, generators, speakers, and sensors, curved magnetic tiles have become increasingly important due to their specific shape and performance requirements. These magnetic tiles typically need to possess high magnetic energy product, good temperature stability, and mechanical strength to meet the needs of various applications. Therefore, the design and manufacturing quality of the molds used to manufacture these magnetic tiles directly affect the performance of the final product. Among different production processes, compression molding is the most common method for forming curved magnetic tiles. It involves placing powdered magnetic material into a mold and pressing it into the desired shape under specific temperature and pressure.

[0003] In actual production, the uniformity of the magnetic tiles after pressing and molding is an important factor affecting their performance. Summary of the Invention

[0004] This invention addresses the problem of uniformity in magnetic tile pressing in existing technologies by providing an arc-shaped magnetic tile forming mold. This mold allows multiple magnetic tiles to be formed simultaneously within a ring cavity, with mutual interference between the tiles, resulting in pressure exchange and balance. The uniformity of the formed magnetic tiles within the same ring cavity is consistent, enabling direct application within a single motor. The specific technical solution is as follows:

[0005] An arc-shaped magnetic tile forming mold includes a base plate, a column set on the base plate, and a top cover covering the other end of the column. The column has an annular cavity, and several sets of partitions are evenly distributed in the circumference of the annular cavity. There is a gap between two adjacent partitions to form a magnetic tile cavity. The partition includes two spaced side pressure heads, and a pressure cavity is formed between the two side pressure heads.

[0006] The column has a secondary channel corresponding to the pressure chamber. In the working state, the secondary channel introduces a medium into the pressure chamber and forces the side pressure head to press the magnetic tile in the magnetic tile cavity.

[0007] The column also has a main passage, and several secondary passages are interconnected through the main passage.

[0008] As a further technical solution of the present invention, a support column is provided between the two side pressure heads, the support column is slidably connected to the two side pressure heads, and the support column is mounted on the base plate.

[0009] As a further technical solution of the present invention, a spring is connected between the support column and the side pressure head.

[0010] As a further technical solution of the present invention, the column includes a central column and an outer ring disposed outside the central column, wherein the central column and the outer ring are arranged at intervals and form an annular cavity.

[0011] As a further technical solution of the present invention, the outer ring includes at least two circumferentially distributed arc plates, and each arc plate is provided with a hydraulic push rod on its outer side. The hydraulic push rod is mounted on the base plate and its output end is connected to the arc plate. In the working state, multiple hydraulic push rods synchronously drive multiple arc plates to retract inward and cooperate with the central column to form the ring cavity.

[0012] The beneficial effects of this invention are as follows:

[0013] (1) In this application, by setting the annular cavity, several magnetic tiles can be formed at the same time. Due to the special nature of the annular cavity, several magnetic tiles will interfere with each other when they are formed at the same time, which can make several magnetic tiles bear the force evenly, thereby improving the uniformity of the magnetic tiles. In other words, after one-time forming, several magnetic tiles in the annular cavity can be used on a motor. This changes the traditional manufacturing method. The magnetic tiles manufactured by the manufacturing method of this application can form a magnetic tile group for the same motor to ensure the magnetic performance of the motor during use.

[0014] (2) In this application, several secondary channels that provide the medium to the pressure chamber are interconnected so that the pressure between the several pressure chambers is the same, so that the pressure can be evenly distributed when the several magnetic tiles interfere with each other during molding, which is beneficial to the uniformity between the multiple magnetic tiles that are molded at the same time.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Figure 1 A schematic diagram of the arc-shaped magnetic tile forming mold is shown; Figure 2 A structural schematic diagram of column 200 is shown; Figure 1 and Figure 2 The arc-shaped magnetic tile forming mold includes a base plate 100, a column 200 disposed on the base plate 100, and a top cover 300 covering the other end of the column 200. The column 200 includes a central column 210 and an outer ring 220 disposed outside the central column 210. The central column 210 and the outer ring 220 are spaced apart and form an annular cavity 230. The annular cavity 230 provides space for the magnetic tile forming and allows several magnetic tiles to be formed simultaneously. Due to the special nature of the annular cavity 230, several magnetic tiles will interfere with each other when formed simultaneously, which can make several magnetic tiles bear force evenly, thereby improving the uniformity of the magnetic tiles. That is to say, after one forming, several magnetic tiles in the annular cavity 230 can be used on a motor. This changes the traditional manufacturing method. The magnetic tiles manufactured using the manufacturing method of this application can form a magnetic tile group for the same motor to ensure the magnetic performance of the motor during use.

[0023] It should be noted that the inner and outer diameters of the annular cavity 230 are customized according to the magnetic tiles to be produced, and are not a limitation of this application.

[0024] Figure 3 A schematic diagram of the outer ring 220 is shown. The outer ring 220 includes four circumferentially distributed arc plates 221. Each arc plate 221 has a hydraulic push rod 222 on its outer side. The hydraulic push rod 222 is mounted on the base plate 100 and its output end is connected to the arc plate 221. In the working state, the four hydraulic push rods 222 synchronously drive the four arc plates 221 to retract inward and cooperate with the central column 210 to form the ring cavity 230. By decomposing an outer ring 220 into four arc plates 221, and using the hydraulic push rods 222 to drive the arc plates 221 to change position, the outer ring 220 can be opened, which is beneficial for the demolding of the magnetic tile after molding. At the same time, after demolding, the hydraulic push rods 222 can drive the arc plates 221 to reset and cooperate with the central column 210 to form the ring cavity 230 again, so as to facilitate reuse.

[0025] It should be noted that in this embodiment, the number of arc plates 221 is four, but in some other embodiments, the number of arc plates 221 is not limited and can be two, three, five, etc. That is to say, the number of arc plates 221 can be two or more.

[0026] Figure 4A schematic diagram of the internal structure of the central column 210 and the annular cavity 230 is shown; Figure 5 A schematic diagram of the structure of the septum 231 is shown; Figure 4 and Figure 5 In the annular cavity 230, several sets of partitions 231 are evenly distributed circumferentially. Adjacent partitions 231 are spaced apart, forming a magnetic tile cavity 232. Each partition 231 includes two spaced-apart side pressure heads 2312, with a pressure cavity 2313 formed between them. A secondary channel 212 corresponding to the pressure cavity 2313 is opened within the central column 210. The secondary channel 212 connects to the pressure cavity 2313. In operation, the secondary channel 212 introduces a medium into the pressure cavity 2313, forcing the side pressure heads 2312 to press against the magnetic tile. The magnetic tiles inside cavity 232; because the secondary channel 212 can introduce pressure medium into the pressure cavity 2313, the two side pressure heads 2312 in the same group of septa 231 can be moved away from each other, that is, the two adjacent side pressure heads 2312 in the adjacent groups of septa 231 on both sides of the annular cavity 230 are brought closer to each other, squeezing the space of the magnetic tile cavity 232, thereby pressing the magnetic tiles inside the magnetic tile cavity 232 to form; a main channel 211 is also opened in the central column 210, and several secondary channels 212 are interconnected through the main channel 211; by Several secondary channels 212 are interconnected, so the medium pressure entering each secondary channel 212 is equal. This allows for pressure distribution when the multiple magnetic tile cavities 232 within the annular cavity 230 interfere with each other, ensuring uniform mass distribution and coordinated operation of the simultaneously formed magnetic tiles. A support column 2311 is provided between the two side pressure heads 2312, and the support column 2311 is slidably connected to the two side pressure heads 2312. The support column 2311 is mounted on the base plate 100. This is because when the outer ring 220 bursts, the diaphragm 231 is subjected to... If the restriction is lifted, the side pressure head 2312 is prone to collapse. However, by using the support column 2311 to restrict the position of the side pressure head 2312, the tilting of the side pressure head 2312 can be prevented. A spring 2314 is connected between the support column 2311 and the side pressure head 2312. The elastic force of the spring 2314 can be used to reset the side pressure head 2312 after the pressure is removed, so that it can be used multiple times. It should be noted that in this embodiment, the spring 2314 is used as the reset elastic element, but in some other embodiments, other elastic elements such as springs, paddles, and elastic ropes can also be used.

[0027] It should be noted that the medium used in this application is a fluid, that is, it can be a gas or a liquid.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
