The formed magnetic material needs to be placed in a sintering furnace for sintering to remove volatile components, promote the reaction between particles, and initially form a magnetic phase.

[0041] A ventilation cavity 1004 is provided inside the tray 1 ; a connector is provided on the left side of the tray 1 , and the connector is connected to the ventilation cavity 1004 ; each limiting hole 1001 of the tray 1 is connected to four ventilation slots 1005 , and the ventilation slots 1005 are connected to the ventilation cavity 1004 .

[0042] The molding process of the magnetic material 5 is to form the mixed magnetic powder into the required shape by pressing. The formed magnetic material 5 needs to be placed in a sintering furnace for sintering to remove volatile components, promote the reaction between particles, and initially form a magnetic phase. However, the magnetic material 5 is usually made in a special mold 4, so it is necessary to first take the magnetic material 5 out of the mold 4, and then manually stack the magnetic material 5 in a special sintering tray. When manually taking the magnetic material 5 out of the mold 4, the force cannot be controlled, which can easily cause damage to the magnetic material 5, and the manual work efficiency is low.

[0043] Meanwhile, the existing small magnetic materials 5 are densely arranged in a special sintering tray by manual stacking and then sent to a sintering furnace for sintering. However, the densely arranged magnetic materials 5 will hinder the circulation of the sintering atmosphere, resulting in insufficient sintering in certain areas, thus affecting the sintering effect.

[0044] To solve the above problem, the first step is to manually turn the mold 4 containing the magnetic material 5 upside down on the pallet 3, and use the positioning block 3002 to assist in placing the mold 4 accurately on the pallet 3 to prevent the mold 4 from being inaccurately aligned with the first connecting hole 3001 of the pallet 3, and to prevent the magnetic material 5 from failing to fall smoothly into the limiting hole 1001 of the tray 1 below. When the mold 4 is positioned, the mold 4 is manually tapped to separate the magnetic material 5 from the mold 4. The separated magnetic material 5 is guided through the first connecting hole 3001 of the pallet 3 and falls downward.

[0045] In the second step, the magnetic material 5 will fall into the corresponding limiting hole 1001 of the tray 1 below. The upper side of the limiting hole 1001 is set to be flared, so that the magnetic material 5 can enter the limiting hole 1001. When the magnetic material 5 falls into the corresponding limiting hole 1001, since the depth of the limiting hole 1001 is one-fourth of the height of the magnetic material 5, the magnetic material 5 will not be excessively tilted, and a certain distance will be maintained with the adjacent magnetic material 5. When all the magnetic materials 5 are transferred to the tray 1, the tray 1 is then placed in the sintering furnace for sintering. The support plate 3 guides the magnetic material 5 so that the magnetic material 5 falls into the limiting hole 1001 corresponding to the tray 1, thereby maintaining a gap between the magnetic materials 5, preventing the densely arranged magnetic materials 5 from hindering the circulation of the sintering atmosphere, and improving the sintering effect. At the same time, the human worker only needs to simply turn the mold 4 upside down on the support plate 3, and there is no need to manually take out the magnetic materials 5 individually from the mold 4, so that the magnetic materials 5 can be kept in a spaced arrangement, thereby improving work efficiency, avoiding direct human contact with the magnetic material 5, avoiding damage to the magnetic material 5, and improving product quality.

[0046] In the first step of the above steps: due to the height difference between the support plate 3 and the tray 1, in the process of manually placing the mold 4 upside down on the support plate 3, due to the flipping of the mold 4, there is a phenomenon that the magnetic material 5 slides out of the mold 4, and the sliding magnetic material 5 collides with the tray 1 and is prone to damage. To avoid the above situation, firstly manually rotate the support plate 3 180 degrees to the right, then place the mold 4 directly below the support plate 3, and align the mold 4 through the positioning block 3002. At this time, the second connecting hole 10501 on the baffle 105 and the first connecting hole 3001 on the support plate 3 are in a state of mutual displacement. Then, manually support the bottom of the mold 4 and press the support plate 3 and the baffle 105 on the upper side, and then rotate it 180 degrees to the left so that the first connecting hole 3001 of the support plate 3 coincides with the limiting hole 1001 of the tray 1 below, and then push the baffle 105 to the right until The second connecting hole 10501 on the baffle 105 is aligned with the first connecting hole 3001 of the support plate 3. The second connecting hole 10501 of the baffle 105 and the first connecting hole 3001 of the support plate 3 are placed in a staggered manner to block the magnetic material 5, thereby preventing part of the magnetic material 5 from falling when the inverted mold 4 is buckled, thereby avoiding damage to the magnetic material 5; based on the view from top to bottom, the limit block 109 is manually rotated counterclockwise to separate the limit block 109 from the fixing rod 107. At this time, the connecting plate 2 is not restricted. The connecting block 108 is manually pushed downward to slide downward on the fixing block 106, thereby driving the connecting plate 2 to slide downward until the limit block 109 contacts the connecting block 108. At this time, the distance between the connecting plate 2 and the tray 1 is greatly reduced, thereby preventing the magnetic material 5 from sliding and colliding with the tray 1 to cause damage, thereby avoiding affecting the product quality.

[0047] In the second step of the above steps: after all the magnetic materials 5 are located in the limiting hole 1001, if the diameter of the magnetic material 5 is smaller than the diameter of the limiting hole 1001, and the magnetic material 5 is excessively tilted after being placed in the limiting hole 1001, resulting in contact between adjacent magnetic materials 5, the slider 1002 on the tray 1 is manually slid to the side away from the connection frame 101, and the connection frame 101 is slowly pressed downward until the block 10101 of the connection frame 101 is located below the buckle 1003 of the tray 1, and the block 10101 is rotated counterclockwise based on the view from top to bottom until the block 10101 is located directly below the buckle 1003 and contacts it, so that the block 10101 is buckled with the buckle 1003, and at the same time, the extrusion rod 102 is pushed in the tray 1 to The adapter block 104 moves downward, and at the same time, the extrusion rod 102 gradually squeezes the adjacent curved rod 103 below, so that the curved rod 103 adjacent to the extrusion rod 102 rotates to the left and right respectively, thereby driving the left and right adapter blocks 104 in the limiting hole 1001 to approach the magnetic material 5 at the same time. Since the adapter block 104 and the curved rod 103 are rotatably connected, the adapter block 104 will rotate to adapt to the shape of the magnetic material 5 until the adapter block 104 fits the surface of the magnetic material 5. At the same time, as the adapter block 104 gradually fits the surface of the magnetic material 5, the magnetic material 5 is fixed, and at the same time, the magnetic material 5 is restricted to gradually become upright and no longer contact with the adjacent magnetic material 5, thereby achieving adaptation to magnetic materials 5 of different diameters and improving the adaptability of the device.

[0048] In the second step of the above steps: when all the magnetic materials 5 are located in the limiting hole 1001 of the tray 1, since the magnetic material 5 is pressed and formed by magnetic powder, part of the powder will fall on the support plate 3 when the bottom of the mold 4 is manually tapped to separate the magnetic material 5 from the mold 4, and part of the powder adhering to the surface of the magnetic material 5 will enter the limiting hole 1001 together with the falling of the magnetic material 5 and the collision with the bottom of the limiting hole 1001. In order to prevent the scattered powder from affecting the sintering effect, the connector of the tray 1 is connected to the exhaust pipe of the external air pump, and the external air pump is started to exhaust air outward, so that the powder enters the ventilation cavity 1004 through the ventilation groove 1005 on the limiting hole 1001 and is then extracted to the outside, thereby achieving the cleaning of the powder and improving the sintering effect.

[0049] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 6 to Figure 7As shown, it also includes a steel wire rope 201, a sealing ring 202 and a limiting ball 203; a steel wire rope 201 is fixedly connected to the lower side of each adapter block 104; a sealing ring 202 is slidably connected in each limiting hole 1001 of the tray 1, and the sealing ring 202 is fixedly connected to the adjacent steel wire rope 201; the sealing ring 202 is located below the notch of the ventilation slot 1005 of the tray 1; two left-right symmetrical limiting balls 203 are arranged in each limiting hole 1001 of the tray 1, and each steel wire rope 201 is slidably connected to the adjacent limiting ball 203.

[0050] In some embodiments of the present invention, in order to reduce the friction between the magnetic material 5 and the sealing ring 202 and prevent the magnetic material 5 from being worn and affecting the sintering quality, the inner ring surface of each sealing ring 202 is set to a curved surface.

[0051] In some embodiments of the present invention, in order to prevent the magnetic material 5 from being damaged, the notch position of each ventilation slot 1005 is higher than the bottom of the limiting hole 1001 .

[0052] During the sintering process, the magnetic material 5 will generate volatile substances and an oxide layer will be formed on the surface of the magnetic material 5 . The generated oxides are likely to block the notches of the ventilation slots 1005 in the limiting holes 1001 .

[0053] To avoid the above situation, in the second step of Example 1: when the adapter block 104 in the limiting hole 1001 of the tray 1 approaches the magnetic material 5 at the same time, the adapter block 104 will pull the adjacent steel wire rope 201, thereby driving the sealing ring 202 on the lower side of the steel wire rope 201 to move upward, thereby blocking the ventilation groove 1005 of the tray 1, thereby preventing the magnetic material 5 from being sintered. The oxides generated in the sintering furnace will clog the ventilation groove 1005, thereby avoiding affecting the subsequent extraction effect of the powder.

[0054] When the magnetic material 5 falls into the limiting hole 1001 , the inner ring surface of each sealing ring 202 is set as an arc surface, thereby reducing the friction between the magnetic material 5 and the sealing ring 202 , preventing the magnetic material 5 from being worn and affecting the sintering quality.

[0055] Since the slot opening of each ventilation slot 1005 is higher than the bottom of the limiting hole 1001 , when the magnetic material 5 leans against the inner wall of the limiting hole 1001 of the tray 1 , the bottom of the magnetic material 5 will not be scratched against the slot opening of the ventilation slot 1005 , thereby preventing the magnetic material 5 from being damaged.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
