Abstract
Description
Technical Field
[0001] The present application relates to the field of mold technology, and in particular to a demoulding mechanism and a mold device with a linkage structure. Background Art
[0002] As plastic product designs become more diverse and complex, the requirements for molds are also increasing. Modern plastic products often require multiple complex demoulding direction features, such as polyhedral structures, complex curved surfaces, and close undercuts.
[0003] In order to achieve these design requirements, the mold needs to be installed with a corresponding demolding structure in each possible demolding direction. Each demolding structure usually includes a cylinder or other mechanical structure to push the mold's sub-plate or other components during the demolding process to ensure that the product is smoothly ejected from the mold. As the number of demolding directions required increases, the size and complexity of the mold also increases, which not only leads to an increase in manufacturing costs, but also increases the difficulty of mold manufacturing and maintenance. Especially when it is necessary to deal with complex undercuts or designs close to undercuts in multiple directions, it becomes extremely complicated to design and implement the demolding structure in each direction separately, and sometimes even difficult to achieve. In this case, if the demolding structure cannot be effectively designed and configured, the product structure may not be implemented normally, affecting product quality and production efficiency.
[0004] Traditional mold design methods often cannot effectively achieve smooth demolding when faced with these complex design requirements, so there is an urgent need to develop a mold with a simple demolding structure that can meet the demolding requirements of undercuts in multiple directions. Utility Model Content
[0005] In order to develop a mold with a simple demoulding structure and capable of meeting the demoulding requirements of multiple directions, the present application provides a demoulding mechanism and a mold device with a linkage structure.
[0006] The present application provides a demoulding mechanism and a mold device with a linkage structure, which adopts the following technical solutions:
[0007] A demoulding mechanism with a linkage structure, used for separating a mold from a product, the demoulding mechanism comprising a driving member, a linkage member, an inclined guide column, and a plurality of slide blocks;
[0008] The inclined guide column passes through the driving member and limits the movement of the driving member, and the linkage member and the plurality of sliders are in contact with the product respectively;
[0009] The linkage member is located between the slider and the driving member, the linkage member is connected to the driving member, the linkage member is slidably connected to the slider via a lever, both ends of the lever are slidably connected to a plurality of sliders and abut against the sliders, and the lever is assembled on the linkage member;
[0010] When opening the mold, the inclined guide column is driven to move, and the inclined guide column releases the constraint on the driving member. The driving member drives the linkage member and the shift rod to move away from the product, and the linkage member is separated from the product. When the shift rod moves, it will resist the movement of the slider, and the slider moves away from the product and separates from the product, completing the demolding work.
[0011] By adopting the above technical scheme, when the mold is closed, the driving member and the inclined guide column are in a fixed state, the linkage member and the slider are in a fixed state, and the slider is in contact with the product; when the mold needs to be opened, the inclined guide column is driven to move, and as the inclined guide column moves, the restriction on the driving member is released, the driving member moves to the side away from the product, and drives the linkage member and the lever to move to the side away from the product, the linkage member is separated from the product, and the lever moves accordingly and abuts against the slider to drive the slider to move, each slider moves according to its design and separates from the product, completing the demoulding process; the demoulding mechanism with a linkage structure of the present application allows a single driving member to control the movement of multiple sliders at the same time, meets the demoulding requirements of complex products with multi-directional undercuts, and improves the flexibility and efficiency of demoulding; compared with the traditional structure that controls the demoulding in each direction separately, the design of the present application can simplify the number of components and the complexity of the mechanism, reduce manufacturing costs and maintenance costs; and through the linkage design, it can reduce the risk of jamming or damage when the slider is separated from the product structure, and improve the service life and stability of the mold.
[0012] In a specific possible implementation scheme, the driving member includes a fixed seat and a spring, the linkage member is connected to the fixed seat, the inclined guide column is passed through the fixed seat and abuts against the fixed seat, the fixed seat abuts against the mold, the fixed seat is provided with a driving groove, the spring is arranged in the driving groove, one side of the spring abuts against the bottom wall of the driving groove, and the other side abuts against the mold.
[0013] By adopting the above technical scheme, when the mold is closed, the fixed seat and the inclined guide column are in a fixed state, and the fixed seat will abut against the mold. At this time, the spring will abut against the driving groove and the mold, and the spring will compress and store force; when the mold needs to be opened, the inclined guide column is driven to move, and the movement of the inclined guide column will release the constraint on the fixed seat and the constraint on the spring at the same time. The spring will push the fixed seat to move to the side away from the product, thereby achieving the purpose of the driving part driving the linkage part to move; in this process, the design and installation of the spring and the fixed seat ensure the force transmission and control during the mold opening process, and the design of the spring makes the movement of the fixed seat balanced and protected during the closing and opening of the mold, thereby reducing the risk of accidents and damage; and the combination of the fixed seat, the inclined guide column and the spring reduces the number and complexity of parts compared to other complex mold opening mechanisms, which not only simplifies assembly and maintenance, but also reduces manufacturing costs.
[0014] In a specific possible implementation manner, a pressing plate is further included, and the fixing seat is located between the pressing plate and the mold, and the fixing seat abuts against the pressing plate and the mold.
[0015] By adopting the above technical solution and utilizing the design of the pressure plate, when the mold is closed and injection molding is in progress, pressure is applied to ensure the correct positioning and shape maintenance between the driving member, the linkage member and the mold, so that the demoulding mechanism can stably contact the product to improve the quality of the product after injection molding; and when the mold is opened, the pressure plate can be removed from the mold to realize the demoulding work of the demoulding mechanism, avoid damage to the mold or the workpiece, and ensure the safety and efficiency of the demoulding mechanism.
[0016] In a specific possible implementation manner, it also includes a stroke control bolt, and the stroke control bolt is located on a side of the fixing seat away from the product.
[0017] By adopting the above technical solution and utilizing the setting of the stroke control bolt, it is possible to ensure that the fixing seat stops at the correct position when the mold is opened and closed, that is, it is possible to ensure that the entire demoulding mechanism stops at the correct position, which helps to protect the mold itself from excessive pressure or accidental collision, and can also ensure that the product is not damaged during the demoulding process; and by controlling the stroke of the demoulding mechanism, it is possible to facilitate the subsequent resetting of the demoulding mechanism, making it easier for the demoulding mechanism to reset to the starting position and prepare for the next production.
[0018] In a specific possible implementation manner, the lever includes a plurality of limiting portions, each of which corresponds to the slider one by one and passes through the slider, and each of which is slidably connected to the slider and abuts against the slider.
[0019] By adopting the above technical solution, when it is necessary to open the mold, the inclined guide column is driven to move. The movement of the inclined guide column will release the constraint on the fixed seat and the spring at the same time. The spring will push the fixed seat to move to the side away from the product, and the fixed seat drives the linkage member and the lever to move. As the lever moves, the limiting part will resist the slider and drive the slider to move, so that the slider moves to the side away from the product and separates from the product, completing the demolding work; through the design of the linkage member, the lever and the limiting part, the movement of the slider during the mold opening process can be controlled to ensure the synchronization between the slider and the linkage rod, and avoid unnecessary damage or delay. The effective linkage design not only improves production efficiency, but also improves operational safety, and simplifies the traditional complex mold opening system structure, reduces the number of components and system complexity, and improves the reliability and stability of the overall system.
[0020] In a specific possible implementation manner, a gap is left between the sliding block and the limiting portion of the lever.
[0021] By adopting the above technical solution, a certain gap is left between the slider and the limiting part of the lever to ensure that during the movement of the slider, even if there is a slight friction or deviation, the lever will not completely fix the slider and make it unable to move, thereby ensuring that the slider can move smoothly when the mold is opened, while avoiding situations that may cause jamming or damage, and optimizing the operating efficiency and reliability of the linkage during the mold opening process.
[0022] In a specific possible implementation mode, the limiting portion is arranged at an angle of 5°-25° to the horizontal direction.
[0023] By adopting the above technical solution, by tilting the limiting part so that it forms a certain angle with the horizontal direction, the freedom of the slider or the lever during movement can be increased, which helps to ensure that the limiting part does not excessively contact or embed into the slider during the movement of the lever, thereby avoiding jamming due to excessive friction or interlocking, and ensuring smoothness and reliability of the mold opening process.
[0024] In a specific possible implementation manner, it further comprises a plurality of bundle blocks, wherein the bundle blocks correspond to the sliders one by one, the bundle blocks are arranged on a side of the slider away from the product, and the bundle blocks abut against the slider.
[0025] By adopting the above technical solution and utilizing the design of the bundle block, when the mold is closed for injection molding, pressure is applied to ensure the correct positioning and shape maintenance between the slider, the product and the linkage, so that the slider can stably contact the product to improve the quality of the product after injection molding; and when the mold is opened, the bundle block can move to release the restriction on the slider so as to realize the demolding work of the demolding mechanism. The bundle block ensures the controllability of the slider during the mold opening process, avoids damage to the mold or workpiece, and ensures the safety and efficiency of the demolding mechanism.
[0026] In a specific possible implementation scheme, it also includes a pressing block, which is fixed on the mold. The slider is provided with a hanging platform structure. The pressing block presses the hanging platform structure against the mold, and the lever first passes through the slider and then is inserted into the pressing block.
[0027] By adopting the above technical solution, the design of the pressure block can limit the movement of the slider and the lever during the injection molding process, ensuring stable injection molding of the product. When the slider exits the product, the pressure block is pressed on the hanging platform structure of the slider. This arrangement effectively limits the possible tilting or deviation of the slider during the process of exiting the product, thereby achieving more stable and precise operation during the demolding process. This stability not only improves product quality and consistency, but also helps to improve production efficiency. The presence of the pressure block ensures the control and stability of the slider during the demolding process, reduces the possibility of accidents, and thus protects the safety of production equipment and operators.
[0028] A mold device comprises the demoulding mechanism with the linkage structure as described above.
[0029] By adopting the above-mentioned technical scheme, the mold device of the present application utilizes the above-mentioned demoulding mechanism with a linkage structure. Through a reliable demoulding mechanism, the mold device can achieve efficient production operation, and the mold device can effectively realize the undercut demoulding requirements in multiple directions. No matter how complex the geometric shape of the product or part is, the demoulding mechanism can flexibly adapt to and complete the demoulding process, and can more easily control and adjust the demoulding process of the mold, thereby improving production efficiency. The demoulding mechanism in the mold device can control the demoulding position, thereby effectively protecting the mold device itself and the products produced from damage or accidental impacts, helping to extend the service life of the mold and improve product quality stability, and enhancing the safety and consistency of production operations.
[0030] In summary, the present application includes at least one of the following beneficial technical effects:
[0031] 1. The demoulding mechanism with linkage structure of the present application allows a single driving member to control the movement of multiple sliders at the same time, meets the demoulding requirements of complex products with multi-directional undercuts, and improves the flexibility and efficiency of demoulding; compared with the traditional structure that controls demoulding in each direction separately, the design of the present application can simplify the number of components and the complexity of the mechanism, and reduce the manufacturing cost and maintenance cost; and through the linkage design, it can reduce the risk of jamming or damage when the slider is separated from the product structure, and improve the service life and stability of the mold;

DETAILED DESCRIPTION
[0040] The following is combined with Figure 1-6 This application is described in further detail.
[0041] Reference Figure 1 The present application embodiment discloses a demoulding mechanism with a linkage structure, which is used to separate the mold 2 from the product 1. In this embodiment, the mold 2 includes a fixed mold and a movable mold, and the fixed mold and the movable mold are respectively provided with a mold core 21, and a cavity corresponding to the product 1 is formed between the two mold cores 21;
[0042] In this embodiment, the demoulding mechanism 3 includes a driving member 4, a linkage member 5, an inclined guide column 6, and a plurality of sliders 7.

In this embodiment, one end of the inclined guide column 6 is fixed on the movable mold, the linkage member 5 is located between the slider 7 and the driving member 4, the linkage member 5 is connected to the driving member 4, the linkage member 5 is slidably connected to the slider 7 through the lever 52, the two ends of the lever 52 are respectively slidably connected to the two sliders 7 and abut against the sliders 7, and the lever 52 is assembled on the linkage member 5;
[0044] When the mold is closed, the driving member 4 and the inclined guide pillar 6 are in a fixed state, the linkage member 5 and the slider 7 are in a fixed state, and the slider 7 is in contact with the structure of the product 1; when the mold needs to be opened, the movable mold is driven to move to drive the inclined guide pillar 6 to move, and as the inclined guide pillar 6 moves, the restriction on the driving member 4 is released, the driving member 4 moves to the side away from the product 1, and drives the linkage member 5 to move to the side away from the product 1, and the linkage member 5 is separated from the product 1. During this process, the linkage member 5 drives the lever 52 to move accordingly, and the lever 52 abuts against the slider 7 to drive the slider 7 to move, and each slider 7 moves according to its design and is separated from the structure of the product 1, completing the demoulding process;
[0045] The demolding mechanism 3 with a linkage structure of the present application allows a single driving component 4 to simultaneously control the movement of multiple sliders 7, thereby meeting the demolding requirements of complex products 1 with multi-directional undercuts, and improving the flexibility and efficiency of demolding; compared with the traditional structure that individually controls the demolding in each direction, the design of the present application can simplify the number of components and the complexity of the mechanism, and reduce manufacturing and maintenance costs; and through the linkage design, it can reduce the risk of jamming or damage when the slider 7 is separated from the product 1 structure, thereby improving the service life and stability of the mold.
[0046] Reference Figure 1 and Figure 2 The driving member 4 includes a fixed seat 41 and a spring 42, the oblique guide column 6 is penetrated through the fixed seat 41 and abuts against the fixed seat 41, the oblique guide column 6 and the fixed seat 41 are slidingly abutted, the fixed seat 41 abuts against the mold core 21 of the fixed mold, the fixed seat 41 is provided with a driving groove 43, and the spring 42 is arranged in the driving groove 43, one side of the spring 42 abuts against the groove bottom wall of the driving groove 43, and the other side abuts against the mold core 21 of the fixed mold; the design and installation of the spring 42 and the fixed seat 41 ensure the force transmission and control during the mold opening process, and the design of the spring 42 makes the movement of the fixed seat 41 balanced and protected during the closing and opening process of the mold 2, thereby reducing the risk of accidents and damage; and the combination of the fixed seat 41, the oblique guide column 6 and the spring 42 reduces the number and complexity of parts compared with other complex mold opening mechanisms, which not only simplifies assembly and maintenance, but also reduces manufacturing costs;
[0047] In this embodiment, the linkage member 5 may be but is not limited to a linkage rod, the lever 52 includes two limiting parts 53, the limiting parts 53 correspond to the slider 7 one by one, the limiting parts 53 pass through the slider 7 and are slidably connected to the slider 7, and the limiting parts 53 and the slider 7 slide against each other; the design of the linkage member 5, the lever 52 and the limiting parts 53 can control the action of the linkage member 5 during the mold opening process, ensure the synchronization between the slider 7 and the linkage member 5, and avoid unnecessary damage or delay. The effective linkage design not only improves production efficiency, but also improves operational safety, simplifies the traditional complex mold opening system structure, reduces the number of components and system complexity, and improves the reliability and stability of the overall system;
[0048] Reference Figure 2 and Figure 3 In this embodiment, when the mold is opened, the movable mold drives the inclined guide column 6 to move upward along the vertical direction z, releasing the restriction on the fixed seat 41, and the fixed seat 41 drives the linkage member 5 and the lever 52 to move in the horizontal reverse direction x to the rear and away from the product 1, and the linkage member 5 exits the product 1. After the movement, the limiting portion 53 of the lever 52 abuts against the slider 7 and drives the slider 7 to move. The two sliders 7 move obliquely backward and away from the product 1 along the inclined directions y1 and y2 respectively, and the slider 7 exits the product 1;
[0049] When the mold is closed, the fixed seat 41 and the inclined guide column 6 are in a fixed state, and the fixed seat 41 will abut against the mold 2. At this time, the spring 42 abuts against the driving groove 43 and the mold 2, and the spring 42 will compress and accumulate force; when the mold needs to be opened, the movable mold is driven to move and drive the inclined guide column 6 to move. As the inclined guide column 6 moves, the constraint on the fixed seat 41 will be released, and the constraint on the spring 42 will be released at the same time. The spring 42 will push the fixed seat 41 to move to the side away from the product 1, and the fixed seat 41 drives the linkage member 5 and the lever 52 to move. As the linkage member 5 moves, the part of the linkage member 5 that contacts the product 1 structure will separate, completing the demolding of the linkage member 5 and the product 1. As the lever 52 moves, the limiting part 53 on the lever 52 will abut against the slider 7, thereby driving the slider 7 to move, so that the slider 7 moves to the side away from the product 1 and separates from the product 1, completing the demolding work.
[0050] A gap 71 is left between the slider 7 and the limiting portion 53 of the lever 52; thereby ensuring that during the movement of the slider 7, even if there is slight friction or deviation, the lever 52 will not completely fix the slider 7 and prevent it from moving, ensuring that the lever 52 and the slider 7 can move smoothly when the mold is opened, while avoiding situations that may cause jamming or damage, and optimizing the operating efficiency and reliability of the linkage part 5 during the mold opening process of the mold 2.
[0051] Reference Figure 4 The limiting portion 53 is tilted, and the angle formed between the limiting portion 53 and the horizontal direction is set to A, and the range of A is 5°-25°; by tilting the limiting portion 53 so that it forms a certain angle with the horizontal direction, the freedom of the slider 7 or the lever 52 during movement can be increased, which helps to ensure that the limiting portion 53 does not excessively contact or embed into the slider 7 during the movement of the lever 52, thereby avoiding jamming due to excessive friction or interlocking, and ensuring smoothness and reliability during the mold opening process.
[0052] Reference Figure 4 and Figure 5The demoulding mechanism 3 also includes a pressing plate 8. In this embodiment, the pressing plate 8 is located on the fixed mold and abuts against the fixed seat 41. The pressing plate 8 partially extends out of the fixed mold and is fixedly connected to the movable mold. The movement of the movable mold drives the fixed seat 41 to move upward along the vertical direction z. The fixed seat 41 is located between the pressing plate 8 and the mold core 21 on the fixed mold, and the fixed seat 41 abuts against the pressing plate 8 and the mold core 21 of the fixed mold. In this embodiment, a supporting inclined surface 81 is provided on the pressing plate 8, and the fixed seat 41 abuts against the supporting inclined surface 81 of the pressing plate 8; when the mold 2 is closed for injection molding, the pressing plate 8 is used to apply pressure to ensure the correct positioning and shape maintenance between the driving member 4 and the linkage member 5 and the mold 2, so that the demoulding mechanism 3 can stably contact with the product 1 to improve the quality of the product 1 after injection molding; when the mold is opened, the pressing plate 8 can be removed from the mold 2 to realize the demoulding work of the demoulding mechanism 3, avoid damage to the mold 2 or the workpiece, and ensure the safety and efficiency of the demoulding mechanism 3.
[0053] Reference Figure 5 In this embodiment, the demolding mechanism 3 also includes two bundle blocks 9, which correspond to the slider 7 one by one. The bundle block 9 is arranged on the side of the slider 7 away from the product 1. The bundle block 9 is partially inserted into the mold core 21 of the fixed mold and abuts against the slider 7. The bundle block 9 is fixed on the movable mold. The movement of the movable mold drives the two trees to move upward along the vertical direction z. In this embodiment, the bundle block 9 is provided with a backhoe slope 91, and the slider 7 abuts against the backhoe slope 91; when the mold 2 is closed for injection molding, the bundle block 9 is used to apply pressure to ensure the correct positioning and shape maintenance between the slider 7 and the product 1 and the linkage 5, so that the slider 7 can stably contact the product 1 to improve the quality of the product 1 after injection molding; when the mold is opened, the bundle block 9 can move to release the restriction on the slider 7 so as to realize the demolding work of the demolding mechanism 3. The bundle block 9 ensures the controllability of the slider 7 during the mold opening process, avoids damage to the mold or workpiece, and ensures the safety and efficiency of the demolding mechanism 3.
[0054] Reference Figure 5The demoulding mechanism 3 also includes a pressing block 10. There are two pressing blocks 10 and they correspond to the slider 7 one by one. In this embodiment, the limiting portion 53 of the lever 52 first passes through the slider 7 and then is inserted into the pressing block 10. The design of the pressing block can limit the movement of the slider 7 and the lever 52 during the injection molding process to ensure stable injection molding of the product 1. The pressing block 10 is fixed on the mold core 21 of the fixed mold. The slider 7 is provided with a hanging platform structure 72. The pressing block 10 presses the hanging platform structure 72 against the mold core 21 of the fixed mold. When the slider 7 exits the product 1, the design of the pressing block 10 can ensure that it presses on the hanging platform structure 72 of the slider 7. This arrangement effectively limits the possible tilting or deviation of the slider 7 during the process of exiting the product 1, thereby achieving more stable and precise operation during the demoulding process. This stability not only improves the quality and consistency of the product 1, but also helps to improve production efficiency. The existence of the pressing block 10 ensures the control and stability of the slider 7 during the demoulding process, reduces the possibility of accidents, and protects the safety of production equipment and operators.
[0055] Reference Figure 6 The demoulding mechanism 3 also includes a stroke control bolt 11, which is arranged on the fixed mold, and the stroke bolt is located on the side of the fixed seat 41 away from the product 1. In the present embodiment, the stroke control bolt 11 is located at the bottom of the pressure plate 8; the setting of the stroke control bolt 11 can ensure that the fixed seat 41 stops at the correct position when the mold 2 is opened and closed, that is, it can ensure that the entire demoulding mechanism 3 stops at the correct position, which helps to protect the mold itself from excessive pressure or accidental collision, and can also ensure that the product 1 is not damaged during the demoulding process; and by controlling the stroke of the demoulding mechanism 3, the subsequent resetting work of the demoulding mechanism 3 can be facilitated, so that the demoulding mechanism 3 is easier to reset to the starting position and prepare for the next production.
[0056] The present application also provides a mold device, including a demolding mechanism 3 with a linkage structure as described above; the mold device of the present application, through a reliable demolding mechanism 3, the mold device can achieve efficient production operation, and the mold device can effectively achieve the undercut demolding requirements in multiple directions, no matter how complex the geometric shape of the product 1 or the part is, the demolding mechanism 3 can flexibly adapt to and complete the demolding process, so that the demolding process of the mold can be more easily controlled and adjusted, and the production efficiency can be improved, and the demolding mechanism 3 in the mold device can control the demolding position, thereby effectively protecting the mold device itself and the produced product 1 from damage or accidental impact, helping to extend the service life of the mold and improve the quality stability of the product 1, and enhancing the safety and consistency of production operations.
[0057] The implementation principle of the embodiment of the present application is: through the demoulding mechanism 3 with a linkage structure, a single driving member 4 is allowed to control the movement of multiple sliders 7 at the same time, so as to meet the demoulding requirements of complex products 1 with multi-directional undercuts, and improve the flexibility and efficiency of demoulding. Compared with the traditional structure of separately controlling the demoulding in each direction, the design of the present application can simplify the number of components and the complexity of the mechanism, and reduce the manufacturing cost and maintenance cost;
[0058] When the mold is closed for injection molding, the fixed seat 41 and the inclined guide column 6 are in a fixed state, the fixed seat 41 will abut against the mold 2, at this time the spring 42 abuts in the driving groove 43 and abuts against the mold 2, and the spring 42 will compress and store force; the pressing plate 8 presses the fixed seat 41 against the mold core 21 of the fixed mold, and applies pressure to ensure the correct positioning and shape maintenance between the entire demoulding mechanism 3 and the mold core 21 of the fixed mold, so that the demoulding mechanism 3 can stably contact with the product 1; the bundle block 9 presses the slider 7, and applies pressure to ensure the correct positioning and shape maintenance between the slider 7 and the product 1 and the linkage member 5, so that the slider 7 can stably contact with the product 1;
[0059] When it is necessary to open the mold, the movable mold is driven to move, driving the inclined guide column 6, the pressure plate 8 and the two beam blocks 9 to move together. As the inclined guide column 6, the pressure plate 8 and the two beam blocks 9 move, the beam block 9 will release the restriction on the slider 7, and the inclined guide column 6 and the pressure plate 8 will release the constraint on the fixed seat 41, and at the same time release the constraint on the spring 42. The spring 42 will push the fixed seat 41 to move to the side away from the product 1, and the fixed seat 41 drives the linkage member 5 and the lever 52 to move. As the linkage member 5 moves, the part of the linkage member 5 that contacts the product 1 structure will separate, and as the lever 52 moves, the lever 52 will release the restriction on the slider 7. The limiting portion 53 on 52 will abut against the slider 7 to drive the slider 7 to move, so that the slider 7 moves to the side away from the product 1 and separates from the product 1. During this process, when the slider 7 moves, the pressure block 10 will press on the hanging platform structure 72 of the slider 7 to limit the movement of the slider 7 and prevent the slider 7 from tilting or offsetting during the process of withdrawing the product 1. When the fixed seat 41 encounters the stroke control bolt 11, the demolding mechanism 3 stops moving. At this time, the linkage member 5 is completely separated from the structure of the product 1, and the slider 7 is completely separated from the structure of the product 1, completing the demolding work.
[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
