[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] This utility model provides a demolding device, such as Figure 1 and Figure 2 As shown, the system includes a base plate 1 and a fixing plate 2. The base plate 1 is used to fix it to an external platform, which can be an operating table or the ground. The base plate 1 and the fixing plate 2 are fixedly connected by several guide pillars 3. In this embodiment, the number of guide pillars 3 is set to four, and the four guide pillars 3 are respectively set at the four corners of the base plate 1 and the fixing plate 2. A mold 100 and a demolding base 200 located below the mold 100 are provided between the fixing plate 2 and the base plate 1. The demolding base 200 is placed on the base plate 1 and is used to receive the workpiece that has detached from the mold 100.

[0034] A pressing mechanism 4 and a buffer mechanism 5 are provided between the base plate 1 and the fixed plate 2. The pressing mechanism 4 is located above the mold 100, and the buffer mechanism 5 is located around the mold 100. The pressing mechanism 4 can demold the workpiece inside the mold 100 after being buffered by the buffer mechanism 5. The height and position of the buffer mechanism 5 are adjustable on the base plate 1. This utility model uses the buffer mechanism 5 to buffer the pressing mechanism 4 beforehand to avoid rigid collisions between the demolding device itself or with the mold 100 during the pressing process, thereby extending the service life of the demolding device and the mold 100. At the same time, it can also significantly reduce the impact on the workpiece and improve the yield rate of the workpiece. The buffer mechanism 5 is height-adjustable and its position above the base plate 1 is adjustable to adjust the buffer stroke to adapt to inductor molds 100 of different sizes. Of course, by configuring the structure of the buffer mechanism 5, it can also abut against the demolding base 200 placed on the base plate 1, limit the demolding base 200, and prevent the demolding base 200 and the mold 100 from swinging too much, which could cause damage to the structure or workpiece.

[0035] In some embodiments, the pressing mechanism 4 includes a driving member 41, a push plate 42, and a punch 43. The push plate 42 is slidably connected to the guide post 3. The driving member 41 is fixedly mounted on the fixed plate 2. One end of the punch 43 passes through the mold 100 and abuts against the workpiece inside the mold 100. The driving member 41 can push the push plate 42 towards the base plate 1, causing it to abut against the other end of the punch 43, thus pushing the workpiece from the mold 100 into the demolding base 200. A buffer mechanism 5 is provided between the base plate 1 and the push plate 42. The height of the energy-absorbing end of the buffer mechanism 5 is higher than the height of the end of the punch 43 extending out of the mold 100, ensuring that the push plate 42 contacts the buffer mechanism 5 first, thereby preventing the punch 43 from being subjected to the instantaneous impact when the driving member 41 is activated. The height and position of the buffer mechanism 5 are adjustable on the base plate 1. Adjusting the height of the buffer mechanism 5 adjusts the buffer stroke, thereby effectively absorbing energy and extending the service life of the punch 43 in the mold 100. It is understandable that the force at the moment of contact between the push plate 42 and the punch 43 is relatively large, so the punch 43 will be damaged quickly after a period of use. The buffer mechanism 5 begins to bear the pushing force before the push plate 42 contacts the punch 43, sharing some of the pressure with the punch 43. At the same time, the height of the buffer mechanism 5 should not be too high, otherwise the demolding device will not have enough pressure to demold. This utility model uses a height-adjustable buffer mechanism 5 to adjust the buffer stroke to adapt to inductor molds of different sizes, avoiding the push plate 42 directly contacting the punch 43 directly during the pressing process and causing a rigid collision. The position of the buffer mechanism 5 on the base plate 1 is adjustable, so that it can abut against the demolding base 200 placed on the base plate 1, limiting the demolding base 200 and preventing the demolding base 200 and the mold 100 from swinging too much and breaking the punch 43. This extends the service life of the punch 43 in the mold 100, and also significantly reduces the impact on the workpiece, improving the workpiece yield. In other alternative embodiments, the punch 43 can also be fixedly connected to the push plate 42, and the punch 43 moves up and down with the push plate 42. In this case, it is only necessary to ensure that the buffer mechanism 5 can contact the push plate 42 before the bottom of the punch 43 contacts the workpiece to achieve buffering. The principle is the same as that in the above embodiments, and will not be repeated here.

[0036] In some embodiments, such as Figure 3 and Figure 4 As shown, the buffer mechanism 5 includes a buffer 51 and a mounting base 52. The mounting base 52 is adjustablely positioned on the base plate 1, and the buffer 51 is adjustablely positioned within the mounting base 52. It can be understood that by adjusting the mounting height of the buffer 51 within the mounting base 52, the buffer stroke can be adjusted to adapt to inductor molds of different sizes. The structure is simple and avoids a rigid collision between the push plate 42 and the punch 43 during the pressing process, thereby extending the service life of the punch 43 in the mold 100. Simultaneously, it significantly reduces the impact on the workpiece and improves the workpiece yield.

[0037] In some embodiments, continue to refer to Figure 3 and Figure 4 The mounting base 52 includes a fixedly connected base 521 and a mounting block 522. The mounting block 522 is threadedly connected to the buffer 51, and the base 521 is detachably connected to the base plate 1. The mounting block 522 protrudes from the base 521, which helps increase the adjustable stroke of the buffer 51's installation height, increases the contact area between the buffer 51 and the mounting base 52, and ensures the assembly stability of the buffer 51 and the mounting base 52. The threaded connection between the mounting block 522 and the buffer 51 allows for arbitrary adjustment of the height of the buffer 51 relative to the mounting block 522. Without a minimum adjustment unit, it can better adapt to different sizes of molds 100 and demolding bases 200. The threaded connection also has self-locking properties, allowing for a certain degree of fixation in any position. The detachable connection between the base 521 and the base plate 1 allows for easy disassembly, adjustment of the base 521's position on the base plate 1, and then re-fixing. The adjustment method is simple and easy to operate.

[0038] In some specific embodiments, the main body of the buffer 51 is provided with external threads, and the mounting block 522 has a mounting hole with internal threads inside. The buffer 51 is threaded into the mounting hole, achieving a threaded connection between the two without significantly altering the existing structure of the buffer 51. This facilitates the coaxial arrangement of the buffer 51 and the mounting block 522, improving the pressure-bearing capacity of the buffer 51. In other alternative embodiments, the main body of the buffer 51 may also have a mounting hole, and the mounting block 522 may have external threads. Since the buffer 51 has an internal buffer damping structure, the two need to be installed eccentrically, allowing the buffer 51 to be closer to or further away from the mold 100. When the buffer 51 is biased towards the mold 100, it can abut against the mold 100, limiting the mold 100 and preventing it from shifting during demolding. When the buffer 51 is biased away from the mold 100, it helps to distribute the pressure on the push plate 42, preventing stress concentration that could damage the push plate 42.

[0039] In some specific embodiments, such as Figure 4As shown, the base 521 has a slot 5211, and the base plate 1 has a plurality of threaded holes 11. These threaded holes 11 are arranged radially at intervals along the demolding base 200. Each slot 5211 corresponds to any two adjacent threaded holes 11 and is fixed by a fixing bolt. The base 521 can have one or two slots 5211. When there are two slots 5211, they are parallel and spaced apart, facilitating correspondence with the threaded holes 11 on the base plate 1. Furthermore, having two slots 5211 makes the connection between the mounting base 52 and the base plate 1 more stable. It is understood that the length of the slot 5211 matches the distance between two adjacent threaded holes 11 along the radial direction of the demolding base 200, preventing the mounting base 52 from moving after being fixed.

[0040] In some embodiments, the mounting base 52 further includes a locking element 53, which can fix the relative position of the buffer 51 and the mounting base 52. Specifically, the locking element 53 is a locking nut. In this embodiment, the main body of the buffer 51 is provided with external threads, and the locking nut is threadedly connected to the main body of the buffer 51. By screwing the locking nut close to the mounting block 522, the buffer 51 and the mounting block 522 are locked by preload, further fixing their positions and ensuring the stability of the structure.

[0041] In some embodiments, the end of the base 521 of the mounting base 52 facing the demolding base 200 is configured as V-shaped or arc-shaped. It is understood that configuring the end of the base 521 facing the demolding base 200 as V-shaped or arc-shaped changes the contact between the base 521 and the demolding base 200 from a single point contact to multi-point contact, line contact, or surface contact, increasing the contact area and making the limiting of the demolding base 200 more stable, further preventing the demolding base 200 from deviating. It should be noted that when there is one buffer mechanism 5, a stop is provided on the bottom plate 1 on the opposite side of the demolding base 200 that abuts against the base 521 of the buffer mechanism 5. When there are two or more buffer mechanisms 5, no stop is needed; the base 521 directly provides a circumferential limiting effect on the demolding base 200.

[0042] In some embodiments, at least two buffer mechanisms 5 are provided, and the at least two buffer mechanisms 5 are arranged circumferentially around the demolding base 200 to achieve a circumferential limiting effect on the demolding base 200, making the limiting of the demolding base 200 more stable and preventing the demolding base 200 from deviating. In some specific embodiments, three buffer mechanisms 5 are provided, two of which are symmetrically arranged on both sides of the base plate 1, and the other is arranged on one side of the line connecting the two symmetrically arranged buffer mechanisms 5, which facilitates the entry or exit of the mold 100 and the demolding base 200.

[0043] In some embodiments, such as Figures 1-3As shown, the movable end of the driving member 41 is movably connected to the push plate 42. In some specific embodiments, a limiting block 421 is provided on the side of the push plate 42 facing the driving member 41. The push plate 42 is movably connected to the movable end of the driving member 41 through the limiting block 421. Specifically, the limiting block 421 encloses a limiting space, within which the movable end of the driving member 41 can move along its own direction of movement. The size of the limiting space is set such that there is a gap between the movable end of the driving member 41 and the push plate 42, but this does not affect the movable end of the driving member 41 from pushing the push plate 42 downward to achieve demolding. While ensuring normal operation, it also avoids that all the force of the driving member 41 at the moment of start-up is applied to the push plate 42.

[0044] In some embodiments, the drive component 41 is configured as any one of a cylinder, an electric telescopic rod, etc. When the drive component 41 is configured as a cylinder, the push plate 42 can be directly supported by the buffer mechanism 5 or a return spring can be provided between the push plate 42 and the guide post 3 so that the push plate 42 returns to its original position after the working stroke is completed. The return spring can work in conjunction with the buffer mechanism 5 to achieve a buffering effect, further preventing the generation of rigid collisions, which is beneficial to extending the life of the device itself and improving the yield of workpieces.

[0045] In some specific embodiments, the demolding device also includes a start switch. Taking the drive component 41 as a cylinder as an example, the start switch can be a manual valve switch. In other embodiments, the start switch can also be an automatic control valve switch.

[0046] When using the demolding device of this utility model, activating the manual valve switch causes the push rod at the movable end of the cylinder to move downwards. During the downward movement, the push rod first abuts against the push plate 42, and then further pushes the push plate 42 downwards. The push plate 42 moves downwards along the four guide pillars, thereby ensuring that the pressing surface is flat and does not tilt. The pressing surface of the push plate 42 contacts the buffer structure, and is buffered by the buffer mechanism 5, effectively absorbing the impact energy generated by the instantaneous collision. Then it contacts the punch 43. At this time, under the buffering effect of the buffer mechanism 5 and the delayed contact with the punch 43, the impact force on the punch 43 is greatly reduced, extending the service life of the punch 43. After the push plate 42 contacts the punch 43 again, it continues to push the punch 43 downwards. The punch 43 pushes the workpiece in the mold 100 downwards, and finally detaches from the mold 100 and enters the demolding base 200, completing the demolding.

[0047] The demolding device of this invention effectively absorbs energy and extends the service life of the punch 43 by adjusting the installation height of the buffer 51 within the mounting base 52 to regulate the buffer stroke. Within the design range, the slot 5211 of the limiting anti-slip block can be used to demold products of different mold sizes 100, thus expanding the applicability of the demolding device. By adjusting the installation position of the buffer mechanism 5 through the slot 5211 of the mounting block 522, the demolding base 200 of different sizes can be restricted, preventing the demolding base 200 from moving under force during the pressing process, which could cause the mold 100 to move, break, or break the punch 43. This also significantly reduces the impact on the workpiece and improves the workpiece yield.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
