Description

Technical Field

[0001] This utility model relates to the field of demolding technology, specifically to a demolding mechanism. Background Technology

[0002] In the stretch forming process of metal shells, after processes such as stretching and thinning of the forming ring, due to changes in the material's shape and temperature changes during processing, the metal shell often tightly wraps around the punch (or punch). At this time, a special demolding mechanism is necessary to successfully separate the metal shell from the punch. Therefore, the demolding mechanism is an indispensable key component in metal shell stretch forming equipment. Currently, most existing post-ejection demolding mechanisms are integral, non-separable structures, and their main structural forms can be roughly divided into the following two types: One method uses an elastic rubber ring for demolding. This type of demolding mechanism mainly utilizes the deformation of an elastic body to achieve demolding. Its working principle is as follows: when the metal shell moves with the punch to the demolding mechanism, the elastic rubber ring itself deforms, causing the metal shell to gradually enter the demolding mechanism. Then, the restoring force of the elastic rubber ring separates the metal shell from the punch. However, this demolding mechanism has significant drawbacks. The elastic body (i.e., the rubber ring) is easily damaged during long-term use and requires frequent replacement, increasing maintenance costs and downtime, thus affecting production efficiency. Furthermore, it provides relatively low demolding force, making it only suitable for stretching molding scenarios with low tensile forces. It cannot meet the needs of situations with high tensile forces, thus limiting its applicability. Another method is forced demolding using steel claws. This type of demolding mechanism has chamfered edges on the steel claws and uses springs to reset the claws, thus achieving demolding. However, this method also has significant problems: during the process of the metal shell entering the demolding mechanism, the metal shell will inevitably come into contact with the steel claws. If the spring force driving the claws to reset is too small, the claws may fail to reset properly, thus preventing effective demolding. If the spring force driving the claws to reset is too large, the claws will scratch the surface of the metal shell, affecting the product's appearance quality. Furthermore, the scraping action of the claws can easily cause the product to flip, leading to product scrap and severely impacting the product yield.

[0003] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to provide a demolding mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A demolding mechanism, comprising: A substrate having a first through hole for the product to be demolded to pass through; A demolding component is movably disposed on the substrate and is used to separate the product to be demolded from the punch; A driving component is located on the side of the demolding component; A transmission component is movably disposed on the side of the demolding component; The reset component acts on the demolding component; The demolding mechanism has a demolding state and a non-demolding state: In the demolded state, the driving component drives the demolding component to move from the initial position to the demolding position through the transmission component; In the non-demolding state, the reset member drives the demolding member to move from the demolding position to the initial position, and the drive member or the demolding member drives the transmission member to reset.

[0006] This application describes the substrate with the first direction being the length direction, the second direction being the width direction, and the third direction being the thickness direction (which is also the stamping direction) of the substrate.

[0007] In the processing stage, the punch moves the product to be demolded along the thickness direction of the substrate to achieve stamping (existing technology). In the demolding stage, the punch moves the product to be demolded back to its original position in the opposite direction.

[0008] During the processing stage, the demolding component is in its initial position, which does not affect the punch from driving the product to be demolded into the stamping area. During the demolding stage, the driving component drives the transmission component, which in turn drives the demolding component to move from the initial position to the demolding position. After that, the punch resets and can pass through the first through hole normally without being obstructed by the demolding component. The end face of the product to be demolded gradually comes into contact with the demolding component and cannot be completely reset, thus separating from the punch and achieving demolding.

[0009] In the above solution, on the one hand, the demolding component is used to prevent the product to be demolded from returning to the initial area with the punch to achieve demolding. By limiting the demolding position, the demolding component can effectively avoid scratching the punch and the product to be demolded. On the other hand, through the cooperation of the driving component, the transmission component and the resetting component, the demolding component can stably move from the initial position to the demolding position and stably move from the demolding position to the initial position, achieving long-term operational stability, effectively ensuring long-term demolding operation and avoiding frequent replacement of related demolding structures.

[0010] The demolding component can be directly driven reciprocally by a drive component, but it can also be driven by a transmission component, or reset by a reset component instead of the drive component, to flexibly meet various needs. For example, if the demolding component includes two demolding blocks that need to move at an angle, using only a drive component, such as a cylinder, would be insufficient because the output area of ​​the cylinder is small, making it difficult to drive both demolding blocks simultaneously. See the following explanation for details.

[0011] Taking a drive component as an example, although the specific method of support is not explicitly described, those skilled in the art will understand that support is a fundamental feature. The drive component can be connected to the substrate to provide support or other support structures can be provided.

[0012] The driving component can be connected to the transmission component, in which case the driving component can drive the transmission component to reset. Alternatively, the transmission component can be disconnected from the driving component, in which case the reset demolding component drives the transmission component to reset.

[0013] In a further technical solution, the demolding component includes four demolding blocks that are movably disposed on the substrate. The four demolding blocks are divided into two groups on average. The two groups of demolding blocks are symmetrically distributed along a first direction, and the two demolding blocks belonging to the same group are symmetrically distributed along a second direction. The first direction and the second direction are orthogonal.

[0014] The first direction can be the length direction of the substrate, and the second direction can be the width direction of the substrate.

[0015] The four demolding blocks can abut against different areas of the end face of the product to be demolded during the resetting process, avoiding the need for the demolding part to fit against the entire end face of the product to be demolded (e.g., by setting an annular block). Based on this, the demolding part does not need to have a large size.

[0016] During the demolding process, multiple areas on the end face of the product to be demolded are subjected to forces from different demolding blocks. Compared with the implementation scheme that only sets one demolding block, this allows the force to be transmitted more evenly to the end face of the product to be demolded, reducing local stress concentration and ensuring the demolding effect.

[0017] In a further technical solution, the demolding block has a demolding surface, which is L-shaped.

[0018] When the demolding surface is L-shaped, it can abut against the corner area (intersection of adjacent sides) of the end face of the product to be demolded. The structural rigidity of the corner of the product to be demolded is usually stronger, and it fits more tightly with the punch during stamping. The demolding block acts at this point, and with the good force characteristics of the corner, it can directly apply force to the part where the product to be demolded and the punch are most tightly connected, effectively breaking the tight fit between the two and ensuring that the product to be demolded can be demolded smoothly.

[0019] To aid understanding, this section is particularly applicable to products without flanges at the ends. When flanges are stretched, the opening (end) of the product to be demolded will not be completely flat, exhibiting unevenness, especially at the four corners. The demolding surface is L-shaped, with rounded corners. The L-shaped demolding surface ensures even force distribution at the four corners during demolding, facilitating easier demolding and reducing the likelihood of deformation at the opening.

[0020] In a further technical solution, the substrate is provided with a plurality of guide grooves corresponding to each of the demolding blocks, and a portion (hereinafter referred to as the protrusion) of each of the demolding blocks is inserted into the corresponding guide groove.

[0021] The protrusion on the demolding block is inserted into the guide groove. This simple solution enables the substrate to support, guide, and limit the demolding block, further preventing damage to the product to be demolded during the demolding process.

[0022] The guide grooves can be inclined (see figure) or extend horizontally along the length of the substrate. Preferably, each guide groove is inclined toward the center area of ​​the first through hole, and the inclination angle is not limited, but can be 15 degrees with the length of the substrate. When the guide grooves are inclined, the demolding block can move simultaneously in the lateral and longitudinal directions to move to the demolding position.

[0023] The guide groove can penetrate the substrate in the thickness direction.

[0024] In a further technical solution, the demolding block has a first surface, and in a third direction, the demolding surface protrudes relative to the first surface; the first direction, the second direction, and the third direction are orthogonal to each other; the third direction is parallel to the thickness direction of the substrate; Each of the first surfaces has the same cover plate on the side away from the substrate.

[0025] The demolding block is slidably connected to the substrate through the engagement of a protrusion and a guide groove. However, with this design, there is a possibility that the protrusion may separate from the guide groove, causing the demolding block to fall off. By having the demolding block clamped and limited by the substrate and a cover plate in the thickness direction of the substrate, this situation is avoided. It should be noted that the cover plate does not necessarily need to be in contact with the first surface; a gap of one millimeter is acceptable. The cover plate can be threaded to the substrate. The driving component can be connected to the cover plate.

[0026] In a further technical solution, in the third direction, the demolding surface protrudes from the side surface of the cover plate away from the substrate (hereinafter referred to as the second surface).

[0027] The reset direction of the product to be demolded is opposite to that of the third direction. After demolding, the product will move downwards under the influence of gravity. If the second surface protrudes from the demolding surface in the third direction, the product will hit the cover plate when falling. Although this generally does not affect the appearance of the product, it will at least change the unloading position, which is not conducive to subsequent processing. By setting the demolding surface to protrude, the product falls directly after separating from the demolding surface, such as landing directly in the predetermined unloading area on the subsequent conveying device, which facilitates subsequent packaging and other processing.

[0028] In a further technical solution, one end of the reset member acts on the cover plate; A first recess is formed on the first surface, and at least a portion of the reset member is accommodated within each of the first recesses.

[0029] The two ends of the reset component act on the demolding block and the cover plate respectively. The first recess avoids the need for a distance between the demolding block and the cover plate due to the presence of the reset component. This distance would affect the limiting effect of the cover plate on the demolding block in the thickness direction of the substrate. Especially when the reset component is elastic, the first recess reduces or eliminates this effect.

[0030] The cover plate may have a second recess, the number of which is the same as the number of the first recess. Preferably, the first and second recesses have the same depth (both preferably half the radial dimension of the reset member), with part of the reset member located in the first recess and the other part in the second recess. Preferably, the first and second recesses extend in the same direction to maximize the restoring force (e.g., elastic restoring force) of the reset member.

[0031] In a further technical solution, the driving component includes two driving sub-components symmetrically arranged in the first direction, and the transmission component includes two transmission sub-components symmetrically arranged in the first direction, wherein any one of the driving sub-components can drive two adjacent demolding blocks through the adjacent transmission sub-components.

[0032] The two drive components ensure that the four demolding blocks move from their initial positions to their demolding positions.

[0033] Initially, the two drive components are positioned on opposite sides of the first through hole. In the demolded state, considering a single drive component, a transmission component is positioned between the drive component and the first through hole. This drive component drives the transmission component, which in turn drives an adjacent set of demolding stops into the demolding position. This transmission component configuration is particularly suitable for driving multiple demolding stops.

[0034] In a further technical solution, the reset component includes four reset springs, each of which acts on each of the demolding blocks in a corresponding manner, so that each demolding block can move from the demolding position to the initial position to achieve reset.

[0035] A further technical solution involves a drive structure on the transmission component, which can be a piston cylinder. When the punch drives the product to be demolded to reset, the end of the product can easily get stuck between the demolding blocks. In this case, the end of the product forms a stepped surface, affecting its subsequent normal descent. By configuring the drive structure, at least a portion of the drive structure is positioned between the first surface and the end face of the product to be demolded. By applying pressure to this end face through the drive structure, the end of the product to be demolded, which can be considered stuck between the demolding blocks, is separated from it, allowing the product to fall normally.

[0036] In a further technical solution, the transmission component is provided with a second through hole, and a limiting component is connected to the substrate. The limiting component is inserted into the second through hole to limit the movement range of the transmission component, thereby further preventing damage to the product to be demolded during the demolding process.

[0037] Holes can be made on the substrate, and the limiting component is inserted and assembled with the substrate through the holes.

[0038] Because the limiting member is inserted into the second through hole, the movable distance of the transmission member in the first direction is limited, which can prevent the transmission member from pushing the demolding member past the demolding position and affecting the reset of the punch.

[0039] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0040] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0041] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0042] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0043] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0044] The working principle and advantages of this utility model are as follows: During the processing stage, the punch moves the product to be demolded along the thickness direction of the substrate, thus achieving the stamping and forming of the product. During the demolding stage, the punch moves the product to be demolded back to its original position in the opposite direction.

[0045] During the processing stage, the demolding component is in its initial position, not affecting the punch's ability to drive the product to be demolded into the stamping area. During the demolding stage, the drive component drives the transmission component, which in turn drives the demolding component to move from its initial position to the demolding position. Afterwards, the punch resets and can pass through the first through hole normally without obstruction from the demolding component. The end face of the product to be demolded gradually comes into contact with the demolding component and cannot fully reset, thus separating from the punch and achieving demolding.

[0046] In the above solution, on the one hand, the demolding component prevents the product to be demolded from returning to the initial area with the punch to achieve demolding. By limiting the demolding position, the demolding component can effectively avoid scratching the punch and the product to be demolded, ensuring the product qualification rate. On the other hand, through the cooperation of the driving component, transmission component and resetting component, the demolding component can stably move from the initial position to the demolding position and stably move from the demolding position to the initial position, achieving long-term operational stability, effectively ensuring long-term demolding operation, avoiding frequent replacement of related demolding structures, and ensuring production efficiency.

[0049] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0050] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0051] See Figures 1-7 A demolding mechanism, comprising: Substrate 1, which has a first through hole 11 for the product 9 to be demolded to pass through; The demolding component 2 is movably disposed on the substrate 1 and is used to separate the product 9 to be demolded from the punch; The driving component 3 is located on the side of the demolding component 2; Transmission component 4 is movably disposed on the side of the demolding component 2; Reset component 5 acts on the demolding component 2; The demolding mechanism has a demolding state and a non-demolding state: In the demolded state, the driving component 3 drives the demolding component 2 to move from the initial position to the demolding position through the transmission component 4; In the non-demolding state, the reset member 5 drives the demolding member 2 to move from the demolding position to the initial position, and the drive member 3 or the demolding member 2 drives the transmission member 4 to reset.

[0052] This embodiment is described with the first direction being the length direction of substrate 1, the second direction being the width direction of substrate 1, and the third direction being the thickness direction of substrate 1 (which is also the stamping direction).

[0053] During the processing stage, the punch moves the product 9 to be demolded along the thickness direction of the substrate 1 to achieve stamping and forming of the product 9 (prior art). During the demolding stage, the punch moves the product 9 to be demolded back to its original position in the opposite direction (prior art).

[0054] During the processing stage, the demolding component 2 is in its initial position, which does not affect the punch from driving the product 9 to be demolded into the stamping area. During the demolding stage, the driving component 3 drives the transmission component 4, which in turn drives the demolding component 2 to move from the initial position to the demolding position. After that, the punch resets and can pass through the first through hole 11 normally without being obstructed by the demolding component 2. The end face of the product 9 to be demolded gradually comes into contact with the demolding component 2 and cannot be completely reset, thus separating from the punch and achieving demolding.

[0055] In the above solution, on the one hand, the demolding component 2 is used to prevent the product 9 to be demolded from returning to the initial area with the punch to achieve demolding. By limiting the demolding position, the demolding component 2 can effectively avoid scratching the punch and the product 9 to be demolded, thus ensuring the product qualification rate. On the other hand, through the cooperation of the driving component 3, the transmission component 4 and the resetting component 5, the demolding component 2 can stably move from the initial position to the demolding position and stably move from the demolding position to the initial position, thus achieving long-term operational stability, effectively ensuring long-term demolding operation, avoiding frequent replacement of related demolding structures, and ensuring production efficiency.

[0056] The demolding component 2 can be directly driven reciprocally by the driving component 3, but it can also be driven by the transmission component 4, and the demolding component 2 can be reset by the reset component 5 instead of the driving component 3, thus flexibly adapting to various needs. For example, the demolding component 2 includes two demolding blocks 21, and the two demolding blocks 21 need to move at an angle. In this case, if only the driving component 3 is used, such as a cylinder, the output area of ​​the cylinder's output end is small, making it difficult to drive the two demolding blocks 21 simultaneously. See the following description for details.

[0057] Taking the driving component 3 as an example, although it is not explicitly mentioned how the driving component 3 achieves support, those skilled in the art will understand that support is a basic feature. The driving component 3 can be connected to the substrate 1 to achieve support or to provide other support structures.

[0058] The driving component 3 can be connected to the transmission component 4, in which case the driving component 3 can drive the transmission component 4 to reset. Alternatively, the transmission component 4 can not be connected to the driving component 3, in which case the reset demolding component 2 drives the transmission component 4 to reset.

[0059] See Figure 2 In this embodiment, the demolding component 2 includes four demolding blocks 21 movably disposed on the substrate 1. The four demolding blocks 21 are divided into two groups. The two groups of demolding blocks 21 are symmetrically distributed along a first direction, and the two demolding blocks 21 belonging to the same group are symmetrically distributed along a second direction. The first direction and the second direction are orthogonal.

[0060] See Figure 7 Part of the demolding stop 21 is in the initial position, and part of the demolding stop 21 is in the demolding position.

[0061] The first direction can be the length direction of the substrate 1, and the second direction can be the width direction of the substrate 1.

[0062] The four demolding blocks 21 are designed to abut against different areas of the end face of the product 9 during the resetting process, thus avoiding the need for the demolding component 2 to fit against the entire end face of the product 9 (e.g., by setting an annular block). Therefore, the demolding component 2 does not need to have a large size.

[0063] During the demolding process, multiple areas on the end face of the product 9 to be demolded are subjected to forces from different demolding blocks 21. Compared with the implementation scheme that only sets one demolding block 21, the force can be transmitted more evenly to the end face of the product 9 to be demolded, reducing local stress concentration and ensuring the demolding effect.

[0064] See Figure 2 , Figure 4 In this embodiment, the demolding block 21 has a demolding surface 211, which is L-shaped.

[0065] When the demolding surface 211 is L-shaped, it can abut against the corner area (intersection area of ​​adjacent sides) of the end face of the product 9 to be demolded. The structural rigidity at the corner of the product 9 to be demolded is usually stronger, and it fits more tightly with the punch during stamping. The demolding block 21 acts at this point, and with the good force characteristics of the corner, it can directly apply force to the part where the product 9 to be demolded is most tightly joined with the punch, effectively breaking the fit between the two and ensuring that the product 9 to be demolded is successfully demolded.

[0066] To aid understanding, this explanation is particularly relevant to the demolded product 9, which lacks flanges at the ends. When the flanges are stretched, the opening (end) of the demolded product 9 will not be completely flat, exhibiting unevenness, especially at the four corners. The demolding surface 211 is L-shaped, with rounded corners at the edges. The L-shaped demolding surface 211 ensures even force distribution at the four corners during demolding, facilitating easier demolding and reducing the likelihood of deformation at the opening.

[0067] See Figure 4 , Figure 7 In this embodiment, the substrate 1 is provided with a plurality of guide grooves 12 corresponding to each of the demolding blocks 21, and a portion of each demolding block 21 (hereinafter referred to as protrusion 214) is inserted into the corresponding guide groove 12.

[0068] The protrusion 214 on the demolding block 21 is inserted into the guide groove 12. Through a simple solution, the substrate 1 supports, guides and limits the demolding block 21, further preventing damage to the product 9 to be demolded during the demolding process.

[0069] Guide groove 12 can be set at an angle (see) Figure 7 Alternatively, the guide grooves 12 can extend horizontally along the length of the substrate 1. Preferably, each guide groove 12 is inclined toward the center region of the first through hole 11, and the inclination angle is not limited, but can be at an angle of 15 degrees with the length of the substrate 1. When the guide grooves 12 are inclined, the demolding block 21 can move simultaneously in the lateral and longitudinal directions to move to the demolding position.

[0070] The guide groove 12 can penetrate the substrate 1 in the thickness direction.

[0071] See Figure 1 , Figure 4 In this embodiment, the demolding block 21 has a first surface 212, and in the third direction, the demolding surface 211 protrudes relative to the first surface 212; the first direction, the second direction, and the third direction are orthogonal to each other; the third direction is parallel to the thickness direction of the substrate 1. Each of the first surfaces 212 has the same cover plate 6 on the side away from the substrate 1.

[0072] The demolding stop 21 is slidably connected to the substrate 1 through the engagement of the protrusion 214 and the guide groove 12. However, with this configuration, there is a possibility that the protrusion 214 may separate from the guide groove 12, causing the demolding stop 21 to fall off. This situation is avoided by having the substrate 1 and the cover plate 6 clamp and limit the demolding stop 21 in the thickness direction of the substrate 1. It should be noted that the cover plate 6 does not necessarily need to be in contact with the first surface 212; for example, they can be spaced one millimeter apart. The cover plate 6 can be threadedly connected to the substrate 1. The driving member 3 can be connected to the cover plate 6.

[0073] See Figure 3 In this embodiment, in the third direction, the demolding surface 211 protrudes from the side surface of the cover plate 6 away from the substrate 1 (hereinafter referred to as the second surface 61) (or may be flush with it).

[0074] The reset direction of the product 9 to be demolded is opposite to that of the third direction. After demolding, the product 9 will move downwards under the action of gravity. If the second surface 61 protrudes from the demolding surface 211 in the third direction, the product 9 will hit the cover plate 6 when it falls. Although this generally will not affect the appearance of the product 9, it will at least cause a change in the unloading position of the product 9, which is not conducive to subsequent processing of the product 9. By setting the demolding surface 211 to protrude, the product 9 to be demolded falls directly after separating from the demolding surface 211. If it can fall directly into the predetermined unloading area on the subsequent conveying device, it will be convenient for subsequent packaging and other processing.

[0075] See Figure 6 In this embodiment, one end of the reset member 5 acts on the cover plate 6; A first recess 213 is formed on the first surface 212, and at least a portion of the reset member 5 is accommodated in each of the first recesses 213.

[0076] The specific shape of cover plate 6 is not limited; please refer to [reference needed]. Figure 6 .

[0077] The two ends of the reset member 5 act on the demolding block 21 and the cover plate 6 respectively. The first recess 213 avoids the need for a distance between the demolding block 21 and the cover plate 6 due to the presence of the reset member 5. This distance would affect the limiting effect of the cover plate 6 on the demolding block 21 in the thickness direction of the substrate 1. Especially when the reset member 5 is elastic, the first recess 213 reduces or eliminates this effect.

[0078] The cover plate 6 may have a second recess 62, the number of which is the same as the number of first recesses 213. Preferably, the first recesses 213 and the second recesses 62 have the same depth (preferably half the radial dimension of the reset member 5), with part of the reset member 5 located in the first recess 213 and the other part in the second recess 62. Preferably, the first recesses 213 and the second recesses 62 extend in the same direction to maximize the restoring force (such as elastic restoring force) of the reset member 5.

[0079] See Figure 2 In this embodiment, the driving component 3 includes two driving sub-components 31 symmetrically arranged in the first direction, and the transmission component 4 includes two transmission sub-components 41 symmetrically arranged in the first direction. Either driving sub-component 31 can drive two adjacent demolding blocks 21 through the adjacent transmission sub-components 41.

[0080] The two drive components 31 ensure that the four demolding blocks 21 move from the initial position to the demolding position.

[0081] Initially, the two drive components 31 are positioned on opposite sides of the first through hole 11. In the demolded state, using a single drive component 31 as an example, a transmission component 41 is positioned between the drive component 31 and the first through hole 11. The drive component 31 drives the transmission component 41, which in turn drives an adjacent set of demolding stops 21 into the demolding position. The transmission component 4 is particularly suitable for driving multiple demolding stops 21.

[0082] See Figure 2 In this embodiment, the reset member 5 includes four reset springs 51, each of which acts on each of the demolding blocks 21 in a one-to-one correspondence, so that each demolding block 21 can move from the demolding position to the initial position to achieve reset.

[0083] See Figure 2 In this embodiment, the transmission member 4 is provided with a driving structure 7, which can push the product 9 to be demolded along the thickness direction (third direction) of the substrate 1. The driving structure 7 can be a piston cylinder.

[0084] When the punch drives the product 9 to be demolded to reset, the end of the product 9 is prone to getting stuck between the demolding blocks 21. At this time, the end of the product 9 forms a stepped surface, affecting the subsequent normal falling process of the product 9. By setting the drive structure 7, at least a part of the drive structure 7 is located between the first surface 212 and the end face of the product 9 to be demolded. By applying pressure to this end face by the drive structure 7, the end of the product 9 to be demolded, which can be regarded as being stuck between the demolding blocks 21, is separated from it, and then the product 9 to be demolded falls normally.

[0085] See Figure 2 In this embodiment, the transmission member 4 is provided with a second through hole 42 (such as a waist-shaped hole), and a limiting member 8 is connected to the substrate 1. The limiting member 8 is inserted into the second through hole 42 to limit the movement range of the transmission member 4, and further avoids damage to the product 9 to be demolded during the demolding process.

[0086] Holes can be made on the substrate 1, and the limiting member 8 is inserted and assembled with the substrate 1 through the holes.

[0087] Since the limiting member 8 is inserted into the second through hole 42, the movable distance of the transmission member 4 in the first direction is limited, which can prevent the transmission member 4 from pushing the demolding member 2 past the demolding position and affecting the reset of the punch.

[0088] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
