Description

Technical Field

[0001] This utility model relates to the field of flying mold machine disks, and more particularly to a flying mold machine disk applied to the base plate of alloy mold steel mold. Background Technology

[0002] Because the mold is attached to the suction cup during mold fitting, and the mold needs to rotate in the air, the suction force required for safe use is very high. The suction force required by the disk for mold fitting exceeds that of the suction cups used in CNC grinding and other machining processes. Modern precision molds use alloy mold steel for the base plate to ensure accuracy and durability. After the mold is attached, the base plate becomes highly magnetized due to the alloy mold steel, leaving residual magnetism. When the mold needs to be released after fitting, with a normal suction cup structure, the mold cannot detach from the disk surface of the mold flying machine on its own. A crane is needed to forcibly pull the mold off the disk, which can easily damage the mold and the machine, is time-consuming and labor-intensive, and is extremely dangerous. Therefore, how to unload the mold from the alloy mold steel base plate after the disk is demagnetized has become a primary problem to solve. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a flying mold machine disk that can be applied to the base plate of alloy mold steel mold.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The flying mold machine disk applied to the base plate of alloy mold steel mold includes a disk frame, and a number of reversible magnets capable of changing the polarity of the magnetic field are arranged and installed in the disk frame. Each reversible magnet has a magnetic core on the same side, and each magnetic core has an irreversible magnet whose magnetic field polarity cannot be changed around it. Each reversible magnet is surrounded by an excitation coil. When two adjacent excitation coils are energized in opposite directions, the two adjacent excitation coils generate magnetic fields with opposite polarities.

[0005] Preferably, in the two adjacent excitation coils, the two terminals of one excitation coil are connected to the positive and negative terminals of the external power supply in sequence, and the two terminals of the other excitation coil are connected to the negative and positive terminals of the external power supply in sequence, with the current input directions of the two adjacent excitation coils being opposite.

[0006] Specifically, the polarities of each irreversible magnet around the same magnetic core are the same, facing the side of the magnetic core.

[0007] Preferably, each magnetic core is surrounded by a demagnetizing coil.

[0008] Preferably, the disk frame is equipped with a proximity sensor, which may be a proximity sensor of model HLJ30A3-10-J-A2, but is not limited thereto.

[0009] Preferably, a screw is installed inside the disk frame, the screw passing through the magnetic core and the reversible magnet, and the magnetic core and the reversible magnet are fixedly installed inside the disk frame by the screw.

[0010] Preferably, a controller is provided for signal control of components such as proximity sensors and disks, as well as for electrical connection to an external power supply. The controller is a PLC programmable logic controller, which can be a programmable logic controller of model XDS-40T-D, but is not limited thereto.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. By giving the demagnetizing coil a high-frequency vibrating current, the residual magnetism on the mold base plate can be removed, so that there is no magnetic force on the mold base plate, thereby realizing the easy removal of the mold base plate from the mold flying machine, avoiding damage to the mold and the mold flying machine. It is convenient to use, saves time and effort, and effectively solves the problem that the traditional method of using a crane to forcibly pull the mold off the suction cup is easy to damage the mold and the mold flying machine, which is time-consuming and labor-intensive.

[0012] 2. By arranging reversible magnets inside the disk frame, setting irreversible magnets around each magnetic core, and setting excitation coils around each reversible magnet, this structural design allows the two adjacent excitation coils to generate magnetic fields of opposite polarities when energized in the forward and reverse directions respectively. This enables quick magnetization and demagnetization of the disk, and also makes the disk have strong attraction and firmly magnetically attached to the mold base plate.

[0013] 3. It automatically senses the mold base plate by installing a proximity sensor inside the disk frame, ensuring that the disk and the mold base plate are magnetically attached firmly before starting work, thus avoiding accidents caused by the mold base plate falling off the suction cup.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] Reference Figure 1 and Figure 2 As shown, the present invention relates to a flying mold machine disk for use in alloy mold steel mold base plates, comprising a disk frame 1, wherein a plurality of reversible magnets 2 capable of changing the polarity of the magnetic field are arranged and installed inside the disk frame 1, each reversible magnet 2 having a magnetic core 3 on the same side, and each magnetic core 3 having an irreversible magnet 4 whose magnetic field polarity cannot be changed around it, and each reversible magnet 2 having an excitation coil 5 surrounding it, wherein two adjacent excitation coils 5 are energized in opposite directions respectively, and the two adjacent excitation coils 5 generate magnetic fields with opposite polarities; one or more rotating shafts 6 are provided on one side of the disk frame 1.

[0022] Reference Figure 2 As shown, in the two adjacent excitation coils 5, the two terminals of one excitation coil 5 are connected to the positive and negative terminals of the external power supply in sequence, respectively, and the two terminals of the other excitation coil 5 are connected to the negative and positive terminals of the external power supply in sequence, respectively. The current input directions of the two adjacent excitation coils 5 are opposite.

[0023] By adopting the above technical solution, when magnetizing the disk, the external power supply energizes the two adjacent excitation coils 5 in opposite directions. The current input directions of the two adjacent excitation coils 5 are opposite, and the two adjacent excitation coils 5 generate magnetic fields with opposite polarities. The two adjacent excitation coils 5 magnetize their respective reversible magnets 2, and the two adjacent reversible magnets 2 generate magnetic fields with opposite polarities.

[0024] Reference Figures 2 to 3 As shown, the polarities of the irreversible magnets 4 around the same magnetic core 3 facing the side of the magnetic core 3 are the same.

[0025] By adopting the above technical solution, when the mold 11 is placed on the disk and the disk is magnetized, the polarity of the contact surface of the reversible magnet 2 facing the side of the magnetic core 3 is the same as the polarity of the side of each irreversible magnet 4 around the same magnetic core 3 facing the magnetic core 3. The polarities of two adjacent magnetic cores 3 are opposite. According to the principle that opposite magnetic poles attract each other, the magnetic lines of force of the reversible magnet 2 and the irreversible magnet 2 pass through the mold base plate 10 to form a closed magnetic circuit with a larger magnetic flux. When the mold base plate 10 covers multiple magnetic cores 3, the mold base plate 10 is attracted and locked by the disk. The magnetic attraction of the disk is strong, and the attraction of the disk to the mold base plate 10 is strong. When the disk is demagnetized, the external power supply supplies power to the two adjacent excitation coils 5 in the opposite direction. At this time, the current input direction of the two adjacent excitation coils 5 is opposite to their original current input direction, which changes the magnetic field polarity of the reversible magnet 2. The two adjacent excitation coils 5 generate magnetic fields with opposite polarities. The two adjacent excitation coils 5 magnetize their respective reversible magnets 2. The two adjacent reversible magnets 2 generate magnetic fields with opposite polarities. The polarity of the surface of the reversible magnet 2 that contacts the corresponding magnetic core 3 is opposite to the polarity of the irreversible magnets 4 around the same magnetic core 3 facing the side of the magnetic core 3. According to the principle that opposite poles attract each other, the magnetic lines of force pass through the magnetic core 3 to form a closed loop, and the surface of the magnetic core 3 does not generate magnetic force on the outside.

[0026] Reference Figures 2 to 4 As shown, each magnetic core 3 is surrounded by a demagnetizing coil 7.

[0027] Reference Figure 4 As shown, by adopting the above technical solution, since the mold base plate 10 is made of alloy mold steel, there will be residual magnetism on the magnetized mold base plate 10. When the mold base plate 10 is attracted to the magnetic core 3, the mold base plate 10 cannot be removed from the disk. By providing a high-frequency vibrating current to the demagnetizing coil 7, the residual magnetism on the mold base plate 10 is removed, so that there is no magnetic force on the mold base plate 10, thereby realizing the easy removal of the mold base plate 10 from the flying mold machine.

[0028] Reference Figures 2 to 4 As shown, a proximity sensor 8 is installed inside the disk frame 1.

[0029] By adopting the above technical solution, when the proximity sensor 8 senses the mold base plate 10, the disk can be firmly attached to the mold base plate 10 and the mold 11 can be flipped and fitted normally. This avoids the mold base plate 10 falling off the suction cup due to the disk not being firmly attached to the mold base plate 10, which would cause danger and ensure the safety of production.

[0030] Reference Figures 1 to 2 As shown, a screw 9 is installed inside the disk frame 1. The screw 9 passes through the magnetic core 3 and the reversible magnet 2. The magnetic core 3 and the reversible magnet 2 are fixedly installed inside the disk frame 1 by the screw 9.

[0031] In this embodiment, the disk frame 1 is filled with epoxy resin. The epoxy resin is used to fill the gap between the irreversible magnet 4, demagnetizing coil 7, magnetic core 3, reversible magnet 2, screw 9, excitation coil 5, proximity sensor 8 and the disk frame 1, and to protect the components inside the disk frame 1 from corrosion and damage, making them durable and reliable.

[0032] Reference Figures 1 to 4 As shown, the working principle of the flying mold machine disk applied to the base plate of alloy mold steel mold is as follows: it automatically demagnetizes the residual magnetism of the mold base plate 10 made of alloy mold steel by using high-frequency oscillation demagnetization of the demagnetizing coil 7. The principle of high-frequency oscillation demagnetization is based on the reverse magnetization mechanism. When the pulsed magnetic field generated by high-frequency oscillation acts on the magnetic material, the direction of the magnetic field reverses rapidly in a very short time, causing the magnetic particles or magnetic domains to align in reverse, thereby weakening or eliminating the original magnetism. When it adsorbs a workpiece, the excitation coil 5 needs to be energized to activate the magnetism of the reversible magnet 2. The magnetic lines of force are transmitted to the magnetic core 3 and superimposed with the magnetic field of the irreversible magnet 2 around each magnetic core 3. The superimposed magnetic field passes through the magnetic core 3 and then through the mold base plate 10 together, and the mold base plate 10 is firmly adsorbed onto the disk frame 1. When the mold 11 is assembled and the mold base plate 10 needs to be demagnetized and removed, a reverse current is applied to the excitation coil 5, and the magnetic polarity of the reversible magnet 2 changes. The magnetic field of the reversible magnet 2 and the magnetic field released by the irreversible magnet 2 form a closed-loop magnetic circuit, and the magnetic core 3 loses its magnetic force to the outside. Since the mold base plate 10 is Made of alloy mold steel, the magnetized mold base plate 10 has residual magnetism and is attracted to the magnetic core 3. The mold 11 cannot be removed from the disk of the mold flying machine. By applying a high-frequency vibrating current to the demagnetizing coil 7, the residual magnetism on the mold base plate 10 can be removed, so that there is no magnetic force on the mold base plate 10. This allows the mold base plate 10 to be easily removed from the mold flying machine, avoiding damage to the mold 11 and the mold flying machine. It is convenient to use, saves time and effort, and effectively solves the problem that the traditional method of using a crane to forcibly pull the mold off the suction cup can easily damage the mold and the mold flying machine, which is time-consuming and labor-intensive.
