Technical Field

[0001] This utility model relates to the field of magnetic tile production technology, and in particular to a dry-pressing injection mold for permanent magnet ferrite magnetic tiles. Background Technology

[0002] Magnetic tiles are a type of tile-shaped magnet mainly used in permanent magnet motors. The material of magnetic tiles can be processed using permanent magnet ferrite.

[0003] For the processing of magnetic tiles, the material is injected into the corresponding mold, and the material is pressed into the shape of the magnetic tile by dry pressing. Then the mold is opened, and the magnetic tile blank is removed for subsequent processing.

[0004] When the mold is opened, the magnetic tile blank falls out of the mold. Since it is a blank formed by dry pressing, the magnetic tile blank has a certain initial velocity after falling. The magnetic tile blank hits the platform and generates a reaction force, which causes resonance and has a certain impact on the blank formed by dry pressing.

[0005] In view of this, we propose a dry-pressing injection mold for permanent magnet ferrite tiles. Utility Model Content

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0038] Example 1: A dry-pressing injection mold for permanent magnet ferrite tiles, see [link / reference] Figures 1 to 4 ;

[0039] The system includes mold A3, mold B4, base block A6, base block B7, and horizontal plate 8. Mold A3 and mold B4 are joined to form the main body of the magnetic tile mold. Mold A3 and mold B4 are joined to form the magnetic tile mold cavity. Base block A6 is fixed to the bottom end of mold A3. Base block B7 is fixed to the bottom end of mold B4. The inclined surfaces of base block A6 and base block B7 are opposite each other. Horizontal plate 8 is located between base block A6 and base block B7. The inclined surface at the end of horizontal plate 8 contacts and engages with the inclined surfaces of base block A6 and base block B7, and the inclined surface at the end of horizontal plate 8 makes smooth contact with the inclined surfaces of base block A6 and base block B7. The system also includes a base plate 1, on which base block A6 and base block B7 are movably mounted. A groove at the front end of base plate 1 corresponds to horizontal plate 8. An external robotic arm gripping mechanism can contact horizontal plate 8 through the groove at the front end of base plate 1 to remove the magnetic tile blank. A vertical plate 2 is fixedly provided at the rear end of the base plate 1. The vertical plate 2 and the base plate 1 are fixed on the corresponding frame. The vertical plate 2 is connected to the mold A3 and the mold B4 through the drive structure 5.

[0040] The drive structure 5 includes a motor body 501, a connecting plate 503, and a threaded screw 502. The motor body 501 is fixed on the vertical plate 2. The motor body 501 can be selected and used by the technical personnel of this profession according to the actual situation. The two connecting plates 503 are respectively fixed to the rear ends of mold A3 and mold B4. The two threaded sections of the threaded screw 502 are threaded through the two connecting plates 503 respectively. One end of the threaded screw 502 is connected to the drive shaft of the motor body 501. A slide groove 201 is provided on the vertical plate 2. A slider 504 is fixed to the rear ends of the two connecting plates 503 respectively. The slider 504 slides in the slide groove 201. When mold A3 and mold B4 move relative to each other or away from each other, the slider 504 moves along the slide groove 201, so that the connecting plate 503 remains stable when it moves. When the slider 504 is at the end of the slide groove 201, the inclined surface of the end of the horizontal plate 8 is in contact with the inclined surfaces of the bottom block A6 and the bottom block B7, which limits the horizontal plate 8. Molds A3 and B4 move away from each other, and bottom blocks A6 and B7 separate. Under the action of gravity, the inclined surface at the end of the horizontal plate 8 slides down along the inclined surfaces of bottom blocks A6 and B7, and the horizontal plate 8 moves down longitudinally, carrying the dry-pressed magnetic tile blank down slowly.

[0041] This utility model, by setting up mold A3, mold B4, bottom block A6, bottom block B7, horizontal plate 8, motor body 501, connecting plate 503 and positive and negative threaded screws 502, has the advantage that the formed magnetic tile blank descends slowly after mold A3 and mold B4 are opened, reducing the impact force. It solves the problem that the magnetic tile blank hitting the platform forms a reaction force that causes resonance, which has a certain impact on the blank formed by dry pressing.

[0042] Example 2: A dry-pressing injection mold for permanent magnet ferrite tiles, see [link / reference] Figure 5

[0043] A groove A801 ​​is provided on the top side of the horizontal plate 8, and a placement plate 9 is placed in the groove A801. Through grooves B802 are provided at the front and rear ends of the horizontal plate 8. Insert blocks 901 are fixed at the front and rear ends of the placement plate 9, and the insert blocks 901 are inserted into and cooperate with the grooves B802. An external robotic arm gripping mechanism grasps the insert block 901 and moves it upwards, thus moving the placement plate 9 upwards from the groove A801. Moving the placement plate 9 forward moves the magnetic tile blank out between molds A3 and B4.

[0044] This utility model, by setting up an embedding groove A801, an embedding groove B802, a placement plate 9, and an insert block 901, has the advantage of being able to have the placement plate 9 picked up by an external robotic arm gripping mechanism, without having to directly grip the magnetic tile blank, thus preventing damage to the magnetic tile blank.

[0045] A limiting groove 902 is provided on the top side of the placement plate 9. The limiting groove 902 matches the magnetic tile mold cavity formed after the molds A3 and B4 are connected. The bottom of the magnetic tile blank after dry pressing is located in the limiting groove 902. When the molds A3 and B4 are separated, it can prevent the magnetic tile blank from sticking to the molds A3 or B4, and does not affect the removal of the magnetic tile blank.

[0046] Working principle: When the motor body 501 operates, the rotation of the positive and negative threaded screws 502 causes the two connecting plates 503 to move relative to each other. The slider 504 moves along the slide groove 201, causing molds A3 and B4 to move relative to each other, and bottom blocks A6 and B7 to move relative to each other, clamping the horizontal plate 8. This forces the inclined surface at the end of the horizontal plate 8 to slide along the inclined surfaces of bottom blocks A6 and B7 until molds A3 and B4 are aligned, and bottom blocks A6 and B7 are aligned. The horizontal plate 8 is located at the bottom of the magnetic tile mold cavity of molds A3 and B4. The limiting groove 902 corresponds to the magnetic tile mold cavity formed after molds A3 and B4 are aligned. Material is added into the magnetic tile mold cavity formed after molds A3 and B4 are aligned and extruded to form a magnetic tile blank. Then the motor body... 501 drives the forward and reverse threaded screws 502 to reverse, the two connecting plates 503 move in opposite directions, the slider 504 moves in the opposite direction along the slide groove 201, the molds A3 and B4 move in opposite directions, and the bottom blocks A6 and B7 move in opposite directions. Under the action of gravity, the inclined surface at the end of the horizontal plate 8 slides down along the inclined surfaces of the bottom blocks A6 and B7, the horizontal plate 8 moves down longitudinally, and the magnetic tile blank after dry pressing slowly descends until the slider 504 moves to the end of the slide groove 201. The external robotic arm gripping mechanism grips the insert block 901. After gripping the insert block 901, the insert block 901 is moved up, so that the placement plate 9 can be moved up from the embedded groove A801. The placement plate 9 is moved forward, and the magnetic tile blank is moved out between the molds A3 and B4.
