Description

Technical Field

[0001] This invention belongs to the field of inductive cold pressing technology, specifically an integrally molded inductive cold pressing device and process. Background Technology

[0002] An inductor generally refers to an inductor device, which is a component that converts electrical energy into magnetic energy and stores it. Its structure is similar to that of a transformer, but it has only one winding. The one-piece molding of inductors is to simplify the manufacturing process and reduce production costs. In the molding process, magnetic powder and wire windings need to be combined into a whole structure. Cold pressing can make the magnetic powder tightly wrap the wire windings under pressure at room temperature, without the need for additional processes such as heating and cooling. Molding can be completed by applying pressure directly at room temperature. The production cycle is short, which can improve production efficiency and simplify the production process. It is generally manufactured by a cold pressing machine.

[0003] However, the machine requires changing the upper and lower molds according to the different shapes of the workpieces being produced. However, the existing equipment cannot disassemble and install the upper and lower molds synchronously, which means that the equipment cannot change the upper and lower molds synchronously. This leads to increased downtime and reduced production efficiency. At the same time, errors can easily exist between the installed upper and lower molds, resulting in inaccurate relative positions between them. During the cold pressing process, the workpiece is prone to displacement and deformation, which affects the product size and shape accuracy and reduces the production effect of the equipment.

[0014] The present invention also provides a one-piece molded inductor cold pressing process, comprising the following steps:

[0015] S1. When cold pressing inductors of different sizes and shapes for production, the mold is installed and removed by operating the rotating retaining device.

[0016] S2. Under the action of the conveyor synchronization component, the loading and unloading operations of the mold can be synchronously controlled;

[0017] S3. A pneumatic stop control unit is used to control the loading and unloading status of the mold by the device, so as to limit the mold after installation and avoid misalignment after the device performs continuous cold pressing operation at the mold.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) By rotating the active shaft, the two active pulleys can be driven to rotate synchronously, which in turn drive the driven pulleys to rotate under the action of the transmission belt. This allows the rotating shafts on the two driven pulleys to rotate synchronously, enabling the synchronous operation of the rotary positioning device for mold installation and disassembly. The installation and disassembly operations are performed synchronously, avoiding increased downtime when changing molds and improving the production efficiency of the device. It also avoids errors between the two molds, ensuring that the relative positions of the two molds are accurate during use. This prevents the inductor from shifting or deforming during cold pressing, which could affect the size and shape accuracy of the product, thus improving the production effect of the device. At the same time, sharing a single drive source when performing synchronous loading and unloading operations on the two molds reduces the cost of using the device, reduces the limitations of using the device, and improves the cold pressing effect of the device.

[0020] (2) After the installation of the mold is completed by the rotary positioning device, the pull-out square column is released and reset under the action of the limit spring and the compression spring. The gas between the positioning gas pipe and the rectangular square plate is sent into the U-shaped pipe through the reset movement of the two rectangular square plates. The gas in the U-shaped pipe moves to its two output ends and acts on the guide column, causing the guide column to move in the direction of the rotating gear. This indicates that the guide plate moves. Under the action of the guide slide, the guide plate drives the stop tooth block to move and mesh with the rotating gear, thereby limiting the rotating gear so that it cannot rotate. This prevents the positioning square cylinder from moving after the mold is installed, thus avoiding the mold from being dislodged or shaking due to non-human factors during use. This improves the installation effect of the mold and ensures the safety of the mold during use.

[0021] (3) After the fixed square tube has entered the fixed slot and limited the mold, the fixed square plate is in the fixed slot and in contact with its side wall, indicating that the fixed square plate has been moved into place. By continuing to operate and rotating the shaft, the fixed horizontal plate continues to drive the fixed square tube to move, so that the fixed square tube is limited to move in the fixed square plate, and the fixed spring is in a buffer state, thereby further strengthening the connection strength and friction between the fixed slot and the fixed square plate, avoiding the mold from being unstable or shaking due to non-human factors during use, and further improving the efficiency and effect of the device during use; at the same time, it avoids the frequent contact of the two molds during the continuous cold pressing process, which may cause the mold to dislodge, and improves the loading and unloading effect of the mold.

[0022] (4) When the mold is disassembled and the guide plate moves away from the rotating gear, the positioning base on the guide plate slides at the driving base under the action of the positioning column, so that the positioning spring is in a buffer state. When the mold is installed and the guide plate is reset, the positioning spring is reset. When the stop tooth block meshes with the rotating gear, the stop tooth block cannot continue to move. Since the strength of the positioning spring is greater than that of the guide spring, the positioning spring continues to reset and drives the guide plate to move at the upper limit of the guide slide column, so that the guide spring is in a buffer state. This strengthens the connection strength between the stop tooth block and the rotating gear, avoids the rotating gear from rotating due to non-human factors, and improves the safety and replacement effect of the mold during use. At the same time, the guide spring in the buffer state cannot reset and move. The resulting elastic force will act on the rotating gear, thereby further strengthening the meshing strength between the rotating gear and the stop tooth block. This further avoids the mold from shaking or dislodging during use, which would affect the production effect and efficiency of the device, and further improves the effect of the device on the installation and disassembly of the mold.

[0023] (5) When the upper mold needs to move up and down repeatedly during use, it will cause the positioning air supply pipe and the air supply hose to move back and forth, and at the same time, it will cause the brake cylinder and the brake column to move back and forth. This will cause the inclined surface on the brake block to contact the inclined surface at the brake groove, resulting in the brake block being subjected to extrusion force, which will put the elastic rod in a buffer state. This will allow the device to load and unload the mold synchronously regardless of the position of the upper mold, reducing the limitations of the device during use. Moreover, when the brake cylinder and the brake column need to rotate, they can rotate normally through the contact between the brake block and the side wall of the brake groove, avoiding the lack of contact between the brake cylinder and the brake column. Normal rotation of the brake cylinder affects the synchronous loading and unloading of the mold, thus improving the device's performance. When the brake cylinder moves continuously with the upper mold, another brake groove moves to the front of the brake block, relieving it of the compressive force and allowing it to reset via the elastic rod. This resets the brake block into the brake groove, fixing the position between the brake cylinder and brake cylinder when not in use. This ensures that the brake cylinder and brake cylinder can extend and retract normally without affecting the synchronous loading and unloading of the mold, reducing the device's limitations during use and further improving the device's cold pressing effect.

[0024] (6) When it is necessary to replace the mold, the mold needs to be disassembled. Simply move the retaining square tube until it no longer contacts the retaining slot, so that the retaining square plate on the retaining square tube releases the mold limit and the guide spring in the buffer state is reset, so that the mold can be ejected into the storage box and the mold disassembly operation can be completed. However, when it is necessary to install the mold, by passing the matching mold through the installation slot and moving it into the storage box, the mold is limited to move in the storage box and will contact the pressing square plate, so that it can be limited to move at the guide slide and guide cylinder, so that the guide spring is in a buffer state. Together with the buffering force brought by the rubber buffer pad, the impact force encountered by the mold during installation is reduced, thereby avoiding damage to the mold due to excessive installation force or other non-human factors during the installation process, improving the installation effect and stability of the mold. At the same time, under the action of the rubber buffer pad, the contact friction between the pressing square plate and the mold is increased, avoiding the mold from shaking or dislodging during use, further improving the safety of the mold during installation.

[0025] (7) Pull the pull-out square column outward, causing the pull-out horizontal plate on it to move at the limiting cylinder, so that the limiting spring is in a buffer state. At the same time, the gas in the rectangular square tube is also drawn into the pull-out square tube, so that the two rectangular square plates inside the rectangular square tube move relative to each other, so that the compression spring is in a buffer state, and the rectangular square plates move away from the positioning gas supply pipe, thereby creating a suction force in the area between the two, so that the gas in the positioning gas supply pipe is drawn into the rectangular square tube. The positioning gas supply pipe is connected to the gas supply hose and the U-shaped pipe, so that the two output ends of the U-shaped pipe are created with suction, so that the guide column can be drawn in, and the guide horizontal plate on it is guided by the guide slide column. The downward movement of the stop block away from the rotating gear causes them to disengage, thus releasing the limiting setting on the rotating gear. At this point, the displacement spring, which is in a buffer state, resets because it is no longer limited, thereby causing the fixed square tube to disengage from the mold and releasing the limiting setting on the mold. Since the mold is no longer limited and no external force is applied, the mold can be ejected from the storage box by the reset of the guide spring, thus automatically completing the mold disassembly operation. The operation is convenient and quick and can be completed without the aid of any tools, improving the disassembly effect of the device and the efficiency of mold replacement, and avoiding the reduction of the production efficiency of the device due to increased downtime.

[0026] (8) After the mold moves to the maximum position in the storage box, the rotating shaft is rotated to drive the rotating gear to rotate, so that the rotating gear meshes with the two displacement racks and moves relative to each other. Under the action of the displacement cylinder, the displacement rack moves to the upper limit of the displacement base, so that the displacement spring is in a buffer state and can release the limiting setting of the mold when it is reset. At the same time, under the action of the bending rod, the displacement rack also causes the two fixing horizontal plates to move relative to each other, so that the two fixing horizontal plates move towards the storage box. Then, the fixing square tube on the fixing horizontal plate passes through the storage box and enters the fixing slot, thereby limiting the mold to the current position and completing the mold installation operation. This avoids the mold from dislodging or shaking during use, and further improves the stability of the mold during installation and use. At the same time, the installation and disassembly of the mold can be completed without the aid of any tools, reducing the limitations of the device during use. This allows the device to perform cold pressing molding operations on inductors of different models and shapes, improving the installation and disassembly effect and efficiency of the mold, and improving the use effect and production efficiency of the device.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Implementation examples, by Figures 1 to 12 The present invention includes a cold pressing device body 1, with a through processing slot on the front side of the cold pressing device body 1; two fixing base plates 2 are provided in the processing slot; the two fixing base plates 2 are arranged vertically opposite each other and have a through mounting slot at their center, in which a mold is placed, and the two molds are arranged opposite each other; a rotary fixing device is also provided on the fixing base plate 2, which is used to install and remove the mold at the fixing base plate 2; a rectangular tube 3 is fixedly installed on the side wall of the processing slot, and a pneumatic stop control unit is provided on the rectangular tube 3, which is used to control the loading and unloading state of the mold; an expansion joint is installed on the top wall of the processing slot, and a displacement plate 4 is connected to the output end of the expansion joint, with the fixing base plate 2 on top connected to the bottom of the displacement plate 4; an auxiliary base 5 is fixedly installed on the side wall of the displacement plate 4, and a conveying synchronization component is also provided on the auxiliary base 5, which is used to synchronously control the loading and unloading operation of the mold.

[0044] When the device performs cold pressing operations on inductors of different sizes and shapes for production, it uses a rotating and retaining device to install and remove molds. Under the action of the conveyor synchronization component, the loading and unloading operations of the molds can be controlled synchronously. A pneumatic stop control unit is used to control the loading and unloading status of the molds, and the installed molds are limited to prevent misalignment after the device performs cold pressing operations on the molds.

[0045] The rotary positioning device in this embodiment includes a storage box 6 installed on the back side of two positioning substrates 2, with the storage box 6 corresponding to the mounting groove; a pressing plate 7 is slidably connected inside the storage box 6; a guide groove 8 is also provided inside the storage box 6, and a guide cylinder 9 is fixedly installed inside the guide groove 8, with both the guide cylinder 9 and the guide groove 8 slidingly engaging with the pressing plate 7; a guide spring 10 is sleeved on the guide cylinder 9, with one end of the guide spring 10 fixedly connected to the guide groove 8 and the other end connected to the pressing plate 7. Fixed connection; the pressing square plate 7 is also provided with a rubber buffer pad 11 on the side near the mold, the rubber buffer pad 11 is located on the moving path of the mold passing through the mounting groove and located on the side wall of the inner part of the storage box 6; a rotating shaft 12 is installed on the opposite side of the two storage boxes 6, and a rotating gear 13 is installed at the end of the rotating shaft 12. The rotating gear 13 is meshed with two symmetrical displacement racks 14. Two displacement square plates 15 are symmetrically installed on the side of the displacement racks 14 away from the rotating gear 13. A displacement cylinder 16 is connected to plate 15, and a displacement base 17 is slidably connected to the displacement cylinder 16. The displacement base 17 is fixedly installed on the storage box 6. A displacement spring 18 is sleeved on the displacement cylinder 16. One end of the displacement spring 18 is fixedly connected to the displacement plate 15, and the other end is fixedly connected to the displacement base 17. A bent rod 19 is installed at one of the opposite ends of the two displacement racks 14. A retaining cross plate 31 is also installed at the end of the bent rod 19. The two retaining cross plates 31 are respectively positioned... On both sides of the storage box 6; a retaining tube 32 is also installed on the side of the retaining plate 31 near the storage box 6, and a retaining plate 33 is slidably connected inside the retaining tube 32; a retaining spring 34 is provided inside the retaining tube 32, one end of the retaining spring 34 is fixedly connected to the inner bottom surface of the retaining tube 32, and the other end is fixedly connected to the retaining plate 33 at the side wall inside the retaining tube 32; retaining slots 35 are also provided on both sides of the mold; the retaining tube 32 passes through the storage box 6 and is connected to the retaining slot 35;

[0046] When a mold needs to be replaced, it must be disassembled. Simply move the retaining square tube 32 until it no longer contacts the retaining slot 35, thus releasing the retaining square plate 33 on the retaining square tube 32 from limiting the mold. This allows the guide spring 10, which is in a buffer state, to reset, allowing the mold to be ejected from the storage box 6, completing the mold disassembly operation. However, when a mold needs to be installed, by passing the suitable mold through the mounting slot and moving it into the storage box 6, the mold is limited within the storage box 6 and comes into contact with the pressing square plate 7, allowing it to move in the guide... The limiting movement at the sliding groove 8 and guide cylinder 9 keeps the guide spring 10 in a buffered state. Together with the buffering force provided by the rubber buffer pad 11, it reduces the impact force encountered by the mold during installation, thereby preventing damage to the mold due to excessive installation force or other non-human factors, and improving the installation effect and stability of the mold. At the same time, the rubber buffer pad 11 also increases the contact friction between the pressing square plate 7 and the mold, preventing the mold from shaking or dislodging during use, further improving the safety of the mold during installation.

[0047] After the mold moves to its maximum position within the storage box 6, rotating the rotating shaft 12 causes the rotating gear 13 to rotate, engaging the two displacement racks 14 and causing them to move relative to each other. Under the action of the displacement cylinder 16, the gears move to their upper limit on the displacement base 17, putting the displacement spring 18 in a buffered state, thus releasing the limiting setting on the mold during reset. Simultaneously, under the action of the bending rod 19, the displacement racks 14 also cause the two retaining horizontal plates 31 to move relative to each other, so that both retaining horizontal plates 31 move towards the storage box 6, thereby causing the... The retaining square tube 32 passes through the storage square box 6 and enters the retaining slot 35, thereby limiting the mold to its current position and completing the mold installation operation. This prevents the mold from dislodging or shaking during use, further improving the stability of the mold during installation and use. At the same time, the installation and disassembly of the mold can be completed without the aid of any tools, reducing the limitations of the device during use. This allows the device to perform cold pressing forming operations on inductors of different models and shapes, improving the installation and disassembly effect and efficiency of the mold, thus improving the overall performance and production efficiency of the device.

[0048] Once the retaining square tube 32 has entered the retaining slot 35 and limited the mold, the retaining square plate 33 is now in the retaining slot 35 and in contact with its side wall, indicating that the retaining square plate 33 has moved into place. By continuing to operate and rotating the rotating shaft 12, the retaining horizontal plate 31 continues to drive the retaining square tube 32 to move, so that the retaining square tube 32 is limited within the retaining square plate 33, and the retaining spring 34 is in a buffer state, thereby further strengthening the connection strength and friction between the retaining slot 35 and the retaining square plate 33, avoiding instability or shaking of the mold due to non-human factors during use, and further improving the efficiency and effect of the device during use; at the same time, it avoids frequent contact between the two molds during the continuous cold pressing process, which may cause the mold to dislodge, thus improving the mold loading and unloading effect.

[0049] The pneumatic stop control unit of this embodiment includes a pull-out square tube 20 installed on the side wall of a rectangular square tube 3, and the pull-out square tube 20 is connected to the rectangular square tube 3. A pull-out square column 21 is slidably connected to the pull-out square tube 20. A pull-out horizontal plate 22 is fixedly installed at the end of the pull-out square column 21 away from the rectangular square tube 3. Two symmetrical limiting cylinders 23 are connected through the side of the pull-out horizontal plate 22, and the limiting cylinders 23 are fixedly installed on the rectangular square tube 3. A limiting spring 24 is sleeved on the limiting cylinder 23. One end of the limiting spring 24 is fixedly connected to the rectangular square tube 3, and the other end is fixedly connected to the pull-out horizontal plate 22. The pull-out horizontal plate 22 and the limiting cylinder 24 are connected through the horizontal plate 22. The cylinder 23 is slidably fitted; two symmetrical rectangular plates 25 are slidably connected inside the rectangular tube 3, and the opposing surfaces of the two rectangular plates 25 are connected to a compression spring 26; the top and bottom of the rectangular tube 3 are respectively equipped with positioning air supply pipes 27 that communicate with them, and one end of an air supply hose 28 is slidably connected to the positioning air supply pipe 27, and the air supply hose 28 and the positioning air supply pipe 27 are connected; the other end of the air supply hose 28 is connected to a U-shaped pipe 29, and the two output ends of the U-shaped pipe 29 face the two sides of the rotating gear 13 respectively; a drive base 30 is installed at each of the two output ends of the U-shaped pipe 29, driving... The moving base 30 is installed at the storage box 6; the inner diameter of the gas supply hose 28 is equal to the outer diameter of the positioning gas supply pipe 27; a guide column 36 is slidably connected inside the output end of the U-shaped pipe 29, and a guide plate 37 is installed at the end of the guide column 36 near the rotating gear 13. Two through guide sliding columns 38 are symmetrically installed on the side of the guide plate 37 near the rotating gear 13, and the guide sliding columns 38 and the guide plate 37 are slidably engaged; the ends of the two guide sliding columns 38 near the rotating gear 13 are connected to a stop tooth block 39, and the stop tooth block 39 meshes with the rotating gear 13; the guide sliding columns 38 are fitted with... A guide spring 40 is provided, one end of which is connected to a guide limiting plate 41. The guide limiting plate 41 is installed on the end of the guide slide column 38 away from the rotating gear 13. The other end of the guide spring 40 is fixedly connected to a guide horizontal plate 37. A positioning base 42 is also installed on the guide horizontal plate 37. A positioning square post 43 is fixedly installed on the side of the positioning base 42 near the drive base 30. The positioning square post 43 passes through the drive base 30 and the two slide in cooperation. A positioning spring 44 is sleeved on the positioning square post 43. One end of the positioning spring 44 is fixedly connected to the positioning base 42, and the other end is fixedly connected to the drive base 30.

[0050] When a mold needs to be changed, the pull-out column 21 is pulled outward, causing the pull-out horizontal plate 22 to move at the limiting column 23, thus putting the limiting spring 24 in a buffered state. Simultaneously, the gas inside the rectangular tube 3 is drawn into the pull-out tube 20, creating suction within the rectangular tube 3 and causing the two rectangular plates 25 inside to move relative to each other. This puts the compression spring 26 in a buffered state, causing the rectangular plates 25 to move away from the positioning air supply pipe 27, creating suction in the area between them. This allows the gas in the positioning air supply pipe 27 to be drawn into the rectangular tube 3. The positioning air supply pipe 27 is connected to the air supply hose 28 and the U-shaped pipe 29, creating suction at the two output ends of the U-shaped pipe 29, which in turn draws the guide column 36 in, causing its... Under the action of the guide slide 38, the guide plate 37 drives the stop block 39 away from the rotating gear 13, so that the two are no longer meshed, thereby releasing the limiting setting on the rotating gear 13. At this time, the displacement spring 18, which is in a buffer state, is reset because it is no longer limited, thereby driving the fixed square tube 32 to no longer connect to the mold, thus releasing the limiting setting on the mold. At this time, the mold is no longer limited and no external force is applied. Through the reset of the guide spring 10, the mold can be ejected into the storage box 6, thereby automatically completing the mold disassembly operation. The operation is convenient and quick and can be completed without the aid of any tools, improving the disassembly effect of the device on the mold and improving the efficiency of the device to change the mold, avoiding the reduction of the production efficiency of the device due to the increase of the device downtime.

[0051] After the rotary positioning device completes the installation operation of the mold, the pull-out square column 21 is released, allowing it to reset and move under the action of the limit spring 24 and the compression spring 26. This allows the gas between the positioning air supply pipe 27 and the rectangular square plate 25 to be sent into the U-shaped pipe 29 as the two rectangular square plates 25 reset and move. This causes the gas in the U-shaped pipe 29 to move to its two output ends and act on the guide column 36, causing the guide column 36 to move in the direction of the rotating gear 13. This indicates that the guide plate 37 is moving, and the guide plate 37, under the action of the guide slide column 38, drives the stop tooth block 39 to move and mesh with the rotating gear 13. This limits the rotating gear 13, preventing it from rotating. This prevents the positioning square cylinder 32 from continuing to move after the mold is installed, thus avoiding the mold from dislodging or shaking due to non-human factors during use. This improves the installation effect of the mold and ensures the safety of the mold during use.

[0052] It is worth mentioning that when the mold is disassembled, causing the guide plate 37 to move away from the rotating gear 13, the positioning base 42 on the guide plate 37 slides at the drive base 30 under the action of the positioning column 43, so that the positioning spring 44 is in a buffer state. When the mold is installed, causing the guide plate 37 to return to its original position, the positioning spring 44 returns to its original position. When the stop block 39 engages with the rotating gear 13, the stop block 39 cannot continue to move. Since the strength of the positioning spring 44 is greater than that of the guide spring 40, the positioning spring 44 continues to return to its original position and drives the guide plate 37 to move at the upper limit of the guide slide column 38. This keeps the guide spring 40 in a buffered state, thereby strengthening the connection between the stop block 39 and the rotating gear 13, preventing the rotating gear 13 from rotating due to non-human factors, and improving the safety and replacement efficiency of the mold during use. At the same time, the guide spring 10, which is in a buffered state, cannot return to its original position, and the resulting elastic force will act on the rotating gear 13, thereby further strengthening the meshing strength between the rotating gear 13 and the stop block 39, further preventing the mold from shaking or dislodging during use, which would affect the production effect and efficiency of the device, and further improving the device's effect on mold installation and disassembly.

[0053] In this embodiment, the drive synchronization assembly includes a drive shaft 45 installed at the bottom of the auxiliary base 5 and the bottom wall of the machining slot. Each of the two drive shafts 45 has a drive pulley 46 mounted at its opposite ends. A transmission belt 47 is connected to the drive pulley 46, and a driven pulley 48 is connected to the end of the transmission belt 47 away from the drive pulley 46. The driven pulley 48 is mounted on the rotating shaft 12. The drive pulley 46 and the driven pulley 48 slide in cooperation with the transmission belt 47. A brake cylinder 49 and a brake cylinder 50 are respectively mounted on the opposite surfaces of the two drive pulleys 46. The brake cylinder 50 is positioned... The brake cylinder 49 is slidably fitted with the brake cylinder 49; the inner wall of the brake cylinder 49 is provided with several brake grooves 51; the brake cylinder 50 is also equipped with a brake base 52 at its end point inside the brake cylinder 49; the brake groove 51 has two symmetrical inclined surfaces, which face the two driving pulleys 46 respectively, and the sharp end of the brake groove 51 faces away from the brake base 52; the brake base 52 is also equipped with an elastic rod 53 on the side near the brake groove 51, and a brake block 54 is installed on the elastic rod 53, and one of the brake grooves 51 is connected to the brake block 54;

[0054] When the device is in use, the two active rotating shafts 45 are connected through the contact of the two active pulleys 46, the brake cylinder 49, and the brake cylinder 50. By rotating the active rotating shafts 45, the two active pulleys 46 are synchronously driven to rotate, which in turn drive the driven pulleys 48 to rotate under the action of the transmission belt 47. This causes the rotating shafts 12 on the two driven pulleys 48 to rotate synchronously, enabling the synchronous operation of the rotary positioning device for mold installation and removal. The installation and removal operations are performed synchronously, avoiding increased downtime when changing molds, thus improving the production efficiency of the device. It also avoids errors between the two molds, ensuring that the relative positions of the two molds are accurate during use. This prevents problems such as inductor displacement and deformation during cold pressing, which could affect the size and shape accuracy of the product, thereby improving the production effect of the device. At the same time, sharing a single drive source when synchronously loading and unloading the two molds reduces the cost of using the device, reduces the limitations of the device in use, and improves the cold pressing effect of the device.

[0055] Simultaneously, when the upper mold needs to move back and forth during use, it causes the positioning air supply pipe 27 and the air supply hose 28 to move back and forth, and also causes the brake cylinder 49 and the brake cylinder 50 to move back and forth. This causes the inclined surface on the brake block 54 to contact the inclined surface at the brake groove 51, resulting in the brake block 54 being subjected to compressive force, which puts the elastic rod 53 in a buffer state. This allows the device to synchronously load and unload the mold regardless of its position, reducing the limitations of the device during use. Furthermore, when the brake cylinder 49 and the brake cylinder 50 need to rotate, they can rotate normally through the contact between the brake block 54 and the side wall of the brake groove 51, avoiding the brake cylinder 49 and the brake cylinder 50 from rotating. The inability to rotate normally between 0 and 0 affects the synchronous loading and unloading operation of the mold, thus improving the use effect of the device. When the brake cylinder 49 moves continuously with the upper mold, it will cause another brake groove 51 to move in front of the brake block 54, so that it is no longer subjected to the extrusion force and is reset by the elastic rod 53. This causes the brake block 54 to reset and move into the brake groove 51, thereby fixing the position between the brake cylinder 49 and the brake cylinder 50 when not in use. This ensures that the brake cylinder 49 and the brake cylinder 50 can extend and retract normally without affecting the synchronous loading and unloading of the mold, reducing the limitations of the device during use and further improving the cold pressing effect of the device.

[0056] The present invention also provides a one-piece molded inductor cold pressing process, comprising the following steps:

[0057] S1. When cold pressing inductors of different sizes and shapes for production, the mold is installed and removed by operating the rotating retaining device.

[0058] S2. Under the action of the conveyor synchronization component, the loading and unloading operations of the mold can be synchronously controlled;

[0059] S3. A pneumatic stop control unit is used to control the loading and unloading status of the mold by the device, so as to limit the mold after installation and avoid misalignment after the device performs continuous cold pressing operation at the mold.
