[0027] The outer side of the buffer pad 13 is flush with the side of the base plate 11. The base plate 11 has recessed positioning grooves 14 on both sides, and the bottom ends of the two positioning grooves 14 penetrate the buffer pad 13. The top of the outer shell 34 is provided with a guide surface 37, and the top of the guide surface 37 is constructed with a guide ball 38. The top of the base 31 is constructed with four guide plates 39 arranged in a ring array at equal intervals around its axis. The bottom of the outer shell 34 is provided with a groove for the guide plates 39 to fit into. The top of the iron core 32 extends into the guide surface 37. The two sides of the guide plates 39 gradually converge upwards into an arc shape. The outer shell 34 is fitted onto the outer edge of the iron core 32.

[0028] Working Principle: In operation, when positioning is required, the control circuit supplies current to the enameled wire 33 of the positioning mechanism 3. According to the principle of electromagnetic induction, the current passing through the enameled wire 33 generates a magnetic field around the iron core 32, magnetizing the iron core 32 and generating a strong electromagnetic force. At this time, under the action of the electromagnetic force, the outer shell 34 quickly and accurately inserts into the preset positioning hole of the equipment, realizing a tight connection and accurate positioning between the lower mold base and the equipment mounting surface. When it is necessary to disassemble the lower mold base, the control circuit cuts off the current to the enameled wire 33, the magnetic field disappears, and the electromagnetic force also disappears. The operator can easily pull the electromagnetic positioning pin out of the positioning hole to complete the disassembly process.
