Only one mold can be processed at a time. After one pressing is completed, the entire demolding and loading process must be completed before the next round can be carried out, which greatly extends the production cycle of a single magnetic core and cannot meet the needs of mass production. Utility Model Content

The output shaft of the second motor 105 is mounted on the bottom of the rod 108 by screws.

[0024] The housing of the first cylinder 202 is mounted on the lower part of the support plate 2 by screws. The output shaft of the first cylinder 202 is mounted on the connecting plate 201 by screws. The slide rod 203 is attached to the inside of the connecting plate 201. The first motor 204 is mounted on the lower part of the connecting plate 201 by screws. The output shaft of the first motor 204 is mounted on the connecting shaft 205 by screws. The pressing head 206 is rotatably connected to the lower part of the connecting shaft 205.

[0025] In this embodiment, as Figure 3 As shown, the insertion rod 108 and the semi-circular plate 109 form a rotating structure through the second motor 105.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the four corners of the limiting plate 107 are provided with incomplete elliptical grooves, and the limiting plate 107 forms a rotating structure through the insert rod 108, and the circular rotating plate 1 forms a rotating structure through the limiting plate 107.

[0027] In this embodiment, as Figure 3 As shown, the push block 102 forms a vertical sliding structure through the second cylinder 103, and the bottom plate of the mold 101 is in contact with the mold 101 limiting ring, and the bottom plate forms a vertical sliding structure through the push block 102.

[0028] In this embodiment, as Figure 3 As shown, the second cylinder 103 is connected to the cylinder controller 104 by a cable, and the push block 102 is provided with a sensing plate inside, which is connected to the cylinder controller 104 by a cable.

[0029] In this embodiment, as Figure 4 As shown, the connecting plate 201 forms a vertical sliding structure through the first cylinder 202, and the four corners of the connecting plate 201 are all attached to the sliding rods 203.

[0030] In this embodiment, as Figure 4 As shown, the pressing head 206 forms a rotating structure through the connecting shaft 205, and the connecting shaft 205 forms a rotating structure through the first motor 204.

[0031] The usage and advantages of this utility model: The working process of the blank pressing machine for processing magnetic cores is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the operator first carefully places the prepared blank into the mold 101. At this time, the first cylinder 202 under the support plate 2 plays a key role. It pushes the connecting plate 201, the first motor 204, the connecting shaft 205, and the pressing head 206 downward in a stable and uniform manner. During this process, the precise control of the first cylinder 202 ensures that the pressing head 206 accurately reaches the appropriate position above the mold 101, providing precise starting conditions for subsequent processing. When the pressing head 206 reaches the designated position, the first motor 204 starts working, causing the connecting shaft 205 and the pressing head 206 to rotate at high speed. This enables the pressing head 206 to rotate at high speed. The blank head 206 applies more uniform pressure to the blank inside the mold 101, thus facilitating the pressing of magnetic cores with regular shapes and high precision. Compared with traditional pressing methods, this rotary pressing greatly improves the quality and consistency of the magnetic cores and reduces the defect rate. After the blank is pressed, the first cylinder 202 systematically drives the connecting plate 201, the first motor 204, the connecting shaft 205, and the pressing head 206 upwards in sequence, quickly resetting to prepare for the next pressing. During this process, the bidirectional stable movement of the first cylinder 202 not only ensures the smooth operation of the equipment but also improves the efficiency of the entire processing flow. Then, the second... Motor 105 starts operating, and its upper output shaft sequentially drives the semi-circular plate 109 and the insertion rod 108 to rotate. When rotated 90 degrees, the rod of the insertion rod 108 precisely rotates and engages in the groove of the limiting plate 107, achieving a reliable limiting function. This ingenious limiting design effectively prevents the circular rotating plate 1 above the limiting plate 107 from shaking or mis-rotating when it does not need to rotate, ensuring the accuracy and stability of switching to the next mold 101. In this way, multiple molds 101 can be processed continuously, greatly improving production efficiency and reducing the time for manual intervention and adjustment. When the mold 101 above the circular rotating plate 1 rotates to the push block 1... When the mold 101 is in the upper position, the sensing block inside the push block 102 comes into play. It can sensitively detect the position of the mold 101 and quickly transmit the signal to the cylinder controller 104. After receiving the signal, the cylinder controller 104 reacts quickly and controls the second cylinder 103 to move the push block 102 upward. This automated detection and control mechanism not only improves the accuracy and timeliness of operation, but also reduces the error of human judgment. The upward movement of the push block 102 can smoothly move the processed blank in the mold 101 upward, making it easy for the operator to remove the blank from the inside of the mold 101, further improving the convenience and efficiency of production.
