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 improve the problem of construction safety during the construction process, 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 molding rod, an inclined guide column, and a plurality of slide blocks, wherein the molding rod and the plurality of slide blocks are in contact with the product;

[0008] The inclined guide column is arranged on the driving member and limits the movement of the driving member. The driving member is connected to the slider through a plurality of limiting rods. The forming rod and the limiting rod are located between the slider and the driving member. The forming rod and the plurality of limiting rods are assembled on the driving member. The limiting rods correspond to the slider one by one. The limiting rods are slidably connected to the slider and abut against the slider.

[0009] When the mold is opened, 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 forming rod and the multiple limiting rods to move away from the product, and the forming rod is separated from the product. When the multiple limiting rods move, they will resist the movement of the slider, and the slider moves away from the product and separates from the product, completing the demolding work.

[0010] By adopting the above-mentioned technical scheme, the present application allows a single driving member to simultaneously control the movement of multiple sliders and forming rods through the design of the driving member, forming rod, slider and limiting rod, and can simultaneously handle the demolding work of multiple directions of the product, ensuring that the structures in different directions can be effectively separated, thereby meeting the needs of complex product design and improving the flexibility and efficiency of demolding; compared with the traditional structure that controls the demolding in each direction separately, 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 is separated from the product structure, thereby improving the service life and stability of the mold.

[0011] In a specific possible implementation scheme, the driving member includes a driving seat and a spring, the forming rod and the plurality of limiting rods are connected to the driving seat, the inclined guide column passes through the driving seat and abuts against the driving seat, the driving seat abuts against the mold, the driving 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.

[0012] By adopting the above technical solution, when the mold needs to be opened, the inclined guide column is driven to move. The movement of the inclined guide column will release the constraint on the drive seat and the spring at the same time. The spring will push the drive seat to move to the side away from the product, thereby achieving the purpose of the drive member driving the limiting rod and the forming rod to move; in this process, the design and installation of the spring and the drive seat ensure the force transmission and control during the mold opening process, and the design of the spring makes the movement of the drive 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 drive seat, the inclined guide column and the spring reduces the number and complexity of parts and reduces the manufacturing cost compared to other complex mold opening mechanisms.

[0013] In a specific possible implementation scheme, it also includes a pressing plate, the driving seat is located between the pressing plate and the mold, and the driving seat abuts against the pressing plate and the mold; when the mold is opened, the pressing plate is driven to move to release the constraint on the driving seat.

[0014] By adopting the above technical solution, when the mold is closed for injection molding, the pressure plate is used to apply pressure to ensure the correct positioning and shape maintenance between the drive seat 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 moved away from the mold to realize the movement of the driving part, thereby realizing the demoulding work of the demoulding mechanism, avoiding damage to the mold or workpiece, and ensuring the safety and efficiency of the demoulding mechanism.

[0015] In a specific embodiment, it further includes a travel bolt, and the travel bolt is located on a side of the driving seat away from the product.

[0016] By adopting the above technical solution, the presence of the stroke bolt ensures precise control during the demoulding process, avoids excessive or insufficient movement of the drive seat, and ensures that the entire demoulding mechanism stops at the correct position. By limiting the stroke of the drive seat, the stroke bolt helps to protect the mold and product from unnecessary damage or pressure; and by controlling the stroke of the demoulding mechanism, it can facilitate the subsequent resetting of the demoulding mechanism, making it easier to reset the demoulding mechanism to the starting position and prepare for the next production.

[0017] In a specific possible implementation scheme, it also includes a plurality of pressing blocks, each of which corresponds to the slider one by one, the limiting rod first passes through the slider and then is inserted into the pressing block, the slider is provided with a hanging platform structure, and the pressing block presses the hanging platform structure against the mold.

[0018] By adopting the above technical solution, when the slider exits the product, the limiting rod moves out of the pressure block and resists the movement of the slider. During the movement of the slider, the pressure block presses on the hanging platform structure of the slider, limiting the possible tilting or deviation of the slider during the process of exiting the product, thereby achieving more stable operation during the demolding process. The presence of the pressure block ensures the control and stability of the slider during the demolding process, reduces the possibility of accidents, and protects the safety of production equipment and operators.

[0019] In a specific possible implementation scheme, the limiting rod is provided with a supporting surface, and during injection molding, the supporting surface abuts against the pressure block; during mold opening, the supporting surface moves to abut against the slider, and the supporting surface abuts the movement of the slider.

[0020] By adopting the above technical scheme, during the injection molding process, the abutting surface of the limiting rod abuts against the pressure block to ensure the fixed and closed state of the mold and guarantee the molding quality of the product; after the injection molding is completed, the limiting rod withdraws from the abutting state with the pressure block, and the abutting surface of the limiting rod abuts against the slider, and drives the slider to move by abutting against it, so as to separate the slider from the product and realize demoulding; the limiting rod controls the position of the slider and the pressure block through the different abutting states of its abutting surface in the injection molding and mold opening stages, thereby ensuring the reliability and stability of the mold injection and demoulding work.

[0021] In a specific possible implementation mode, the abutting surface is arranged at 160°-180° with respect to the horizontal direction.

[0022] By adopting the above technical solution and utilizing the above angle parameter design, it is ensured that during the operation of the mold, the abutment surface and the pressure block or the slider can effectively abut and control the movement at the correct angle; the angle design of the abutment surface allows the contact and movement between the limiting rod and the pressure block to be smooth, avoiding unnecessary friction or jamming; and it can also enable the subsequent abutment surface to abut against the slider well, ensuring the stability and reliability of the movement of the limiting rod against the slider.

[0023] In a specific possible implementation mode, the limiting rod is provided with a constraining inclined surface, and during injection molding, the constraining inclined surface abuts against the slider; during mold opening, when the constraining inclined surface moves to abut against the mold, the limiting rod stops moving.

[0024] By adopting the above technical solution, during the injection molding process, the constraint bevel of the limiting rod abuts against the slider to ensure that the mold completes the injection molding operation in the correct position and state; after the injection molding is completed, the limiting rod moves, and the constraint bevel of the limiting rod will follow the movement until it abuts against the mold, and the limiting rod stops moving; the constraint bevel can control the movement and position of the limiting rod in different working stages to ensure the stability and reliability of the injection molding and mold opening process.

[0025] In a specific possible implementation mode, the constraining slope is set at an angle of 5°-25° with respect to the horizontal direction.

[0026] By adopting the above technical solution, the constraint slope is designed using the above angle parameters, which can prevent the limiting rod from getting stuck or stuck during the movement, so that the limiting rod can move more smoothly in the field and avoid unnecessary friction or resistance; and this angle design also enables the constraint slope to achieve the effect of controlling the movement stroke of the limiting rod, controlling the movement range of the limiting rod to ensure the correct position for demolding, and facilitating the subsequent resetting of the demolding mechanism.

[0027] A mold device comprises the demoulding mechanism as described above.

[0028] By adopting the above-mentioned technical scheme, the mold device of the present application utilizes the above-mentioned demolding mechanism, and the mold device can achieve efficient production operation. The demolding mechanism can effectively realize the undercut demolding requirements in multiple directions. No matter how complex the geometric shape of the product or part is, it can flexibly adapt to and complete the demolding process. The demolding mechanism makes it easier to control and adjust the demolding process of the mold device, improves production efficiency, and the demolding mechanism in the mold device can control the demolding 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.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-6 This application is described in further detail.

[0040] Reference Figure 1 , the embodiment of the present application discloses a demoulding mechanism with a linkage structure, which is used for separating the mold from the product. 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 3 is formed between the two mold cores 21;

[0041] The demoulding mechanism 1 includes a driving member 4, a forming rod 5, an inclined guide column 6, and a plurality of sliders 7. In this embodiment, the sliders 7 include but are not limited to being set to two. The sliders 7 are arranged on the mold core 21. The forming rod 5 and the two sliders 7 are in contact with structures of the product 3 in different directions respectively. In this embodiment, the forming rod 5 is arranged horizontally, and the sliders 7 are symmetrically arranged on both sides of the forming rod 5.

[0042] The inclined guide pin 6 is provided through the driving member 4 and limits the movement of the driving member 4. In this embodiment, the inclined guide pin 6 passes through one side of the driving member 4 and is fixed on the movable mold;

[0043] The driving member 4 is connected to the slider 7 through a plurality of limiting rods 8. The forming rod 5 and the limiting rod 8 are located between the slider 7 and the driving member 4. The forming rod 5 and the plurality of limiting rods 8 are assembled on the driving member 4. The forming rod 5 is located between the two limiting rods 8. The forming rod 5 and the plurality of limiting rods 8 extend to the mold core 21, and the side of the forming rod 5 away from the driving member 4 contacts the product 3. In this embodiment, the limiting rods 8 include but are not limited to being set to two. The limiting rods 8 correspond to the slider 7 one by one. The limiting rods 8 are symmetrically arranged on both sides of the forming rod 5. The side of the limiting rod 8 away from the driving member 4 is slidably connected to the slider 7. The limiting rod 8 abuts against the slider 7 and resists the slider 7 to move.

[0044] In this embodiment, when the mold is opened, the inclined guide pillar 6 moves upward along the vertical direction z following the movable mold, the driving member 4, the limiting rod 8, and the forming rod 5 move backward along the horizontal direction x toward the side away from the product 3, and the two sliders 7 move backward along the oblique rear directions y1 and y2 toward the side away from the product 3 respectively;

[0045] At the beginning of the mold opening process, the movable mold is driven to move, and the movable mold drives the inclined guide pillar 6 to move. The inclined guide pillar 6 releases the constraint on the driving member 4. The driving member 4 will start to move as the constraint is released, and at the same time drive the forming rod 5 and the plurality of limiting rods 8 to move away from the product 3. The movement of the forming rod 5 separates it from the structure of the product 3. At the same time, as the plurality of limiting rods 8 move, the limiting rod 8 will resist the movement of the slider 7. The movement of the slider 7 separates it from the product 3, completing the demoulding process;

[0046] Through the design of the driving member 4, the forming rod 5, the slider 7 and the limiting rod 8, a single driving member 4 can simultaneously control the movement of multiple sliders 7 and the forming rod 5, and can simultaneously handle the demoulding work of multiple directions of the product 3, ensuring that the structures in different directions can be effectively separated, thereby meeting the needs of complex product 3 design and improving the flexibility and efficiency of demoulding; compared with the traditional structure of individually 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 costs; and through the linkage design, it can reduce the risk of jamming or damage when the slider 7 is separated from the product 3 structure, thereby improving the service life and stability of the mold 2.

[0047] The demoulding mechanism 1 further includes a plurality of pressing blocks 11, each of the pressing blocks 11 corresponds to the slider 7 one by one, the limiting rod 8 first passes through the slider 7 and then is inserted into the pressing block 11, the slider 7 abuts against the pressing block 11, the slider 7 is provided with a hanging platform structure 71, and the pressing block 11 abuts the hanging platform structure 71 against the mold core 21;

[0048] During the injection molding process, the pressure block 11 can limit the movement of the slider 7 and the limiting rod 8 to ensure stable injection molding of the product 3. When the slider 7 exits the product 3, the limiting rod 8 moves out of the pressure block 11 and resists the movement of the slider 7. During the movement of the slider 7, the pressure block 11 is pressed on the hanging platform structure 71 of the slider 7 to limit the possible tilting or deviation of the slider 7 during the process of exiting the product 3, thereby achieving more stable and precise operation during the demolding process. This stability not only improves the quality and consistency of the product 3, but also helps to improve production efficiency. The presence of the pressure block 11 ensures the control and stability of the slider 7 during the demolding process, reduces the possibility of accidents, and thus protects the safety of production equipment and operators.

[0049] A gap 12 is left between the limiting rod 8 and the slider 7; thereby ensuring that during the movement of the slider 7 and the limiting rod 8, even if there is slight friction or deviation, the limiting rod 8 will not completely fix the slider 7 and prevent it from moving, ensuring that the slider 7 and the limiting rod 8 can move smoothly during mold opening, while avoiding situations that may cause jamming or damage, and optimizing the operating efficiency and reliability of the linkage design during the mold opening process of the mold 2;

[0050] In this embodiment, a retreat space 14 is reserved between the slider 7 and the mold core 21 of the fixed mold; the design of the retreat space 14 can prevent the slider 7 from getting stuck or jammed due to external factors or component deformation during movement; and can ensure that during operation, even if there is a slight deviation or error in the movement of the slider 7 or the mold 2, it will not cause excessive contact or damage to the mechanical parts, thereby extending the service life of the entire demolding mechanism 1.

[0051] The limiting rod 8 is provided with a supporting surface 81. During injection molding, the supporting surface 81 is in contact with the pressing block 11. During mold opening, the supporting surface 81 moves to contact with the slider 7, and the supporting surface 81 pushes the slider 7 to move.

[0052] The angle formed between the abutting surface 81 and the horizontal direction is set to A, and A is 160°-180°. In the present embodiment, the angle A formed between the abutting surface 81 and the horizontal direction may be, but is not limited to, 180°; the angle design of the abutting surface 81 can ensure that during the movement of the limiting rod 8, the contact and movement between the limiting rod 8 and the pressing block 11 can be carried out smoothly, avoiding unnecessary friction or jamming; and can make the subsequent abutting surface 81 and the slider 7 well abut, ensuring the stability and reliability of the movement of the limiting rod 8 against the slider 7, thereby ensuring that during the operation of the mold 2, the abutting surface 81 and the pressing block 11 or the slider 7 can be effectively abutted and motion controlled at the correct angle;

[0053] The limiting rod 8 is provided with a constraining inclined surface 82. During injection molding, the constraining inclined surface 82 abuts against the slider 7. During mold opening, when the constraining inclined surface 82 moves to abut against the mold core 21, the limiting rod 8 stops moving.

[0054] The angle formed between the constraint slope 82 and the horizontal direction is set to B, and B is 5°-25°. In this embodiment, the angle B formed between the constraint slope 82 and the horizontal direction can be, but is not limited to, 15°; this angle design can prevent the limiting rod 8 from getting stuck or stuck during the movement, so that the limiting rod 8 can move more smoothly on the field and avoid unnecessary friction or resistance; and this angle design also enables the constraint slope 82 to achieve the effect of controlling the movement stroke of the limiting rod 8, controlling the movement range of the limiting rod 8 to ensure the correct position of demoulding, and facilitating the subsequent reset work of the demoulding mechanism 1;

[0055] During the injection molding process, the abutting surface 81 of the limiting rod 8 abuts against the pressing block 11 to ensure the fixed and closed state of the mold 2 and the molding quality of the product 3. At the same time, the restraining inclined surface 82 of the limiting rod 8 abuts against the slider 7 to ensure that the mold 2 completes the injection molding operation in the correct position and state; when the injection molding is completed, the limiting rod 8 withdraws from the abutting state with the pressing block 11, and the abutting surface 81 of the limiting rod 8 abuts against the slider 7, and drives the slider 7 to move by abutting against the slider 7 to achieve the separation of the slider 7 and the product 3. In this process, as the limiting rod 8 moves, the restraining inclined surface 82 of the limiting rod 8 will follow the movement until it abuts against the mold core 21, and the limiting rod 8 stops moving, completing the separation of the slider 7 and the product 3, and completing the demoulding work;

[0056] The limiting rod 8 controls the position of the slider 7 and the pressure block 11 through the different abutment states of its abutment surface 81 in the injection molding and mold opening stages, thereby ensuring the reliability and stability of the injection and demolding operations of the mold 2; and through the design of the constraint slope 82, the movement and position of the limiting rod 8 in different working stages are controlled to ensure the stability and reliability of the injection molding and mold opening processes, while avoiding accidental movement or damage of moving parts.

[0057] The driving member 4 includes a driving seat 41 and a spring 42. The oblique guide column 6 is passed through the driving seat 41 and abuts against the driving seat 41. The driving seat 41 abuts against the outer wall of the mold core 21 of the fixed mold. The molding rod 5 and the two limiting rods 8 are connected to the driving seat 41 on the side away from the product 3. The driving seat 41 is provided with a driving groove 43. The spring 42 is arranged in the driving groove 43. One side of the spring 42 abuts against the 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 driving seat 41 ensure the transmission and control of force during the mold opening process. The design of the spring 42 makes the movement of the driving seat 41 balanced and protected during the closing and opening of the mold 2, thereby reducing the risk of accidents and damage. In addition, the combination of the driving seat 41, the oblique guide column 6 and the spring 42 reduces the number and complexity of parts and reduces the manufacturing cost compared with other complex mold opening mechanisms.

[0058] The demoulding mechanism 1 also includes a pressing plate 9. In this embodiment, the pressing plate 9 is arranged on the fixed mold. The pressing plate 9 passes through one side of the fixed mold and is fixedly connected to the movable mold. The moving direction of the pressing plate 9 is consistent with that of the movable mold. The driving seat 41 is located between the pressing plate 9 and the mold core 21 of the fixed mold. The driving seat 41 abuts against the pressing plate 9 and the mold core 21 of the fixed mold. In this embodiment, two fixed blocks 13 are also provided on the fixed mold. The fixed blocks 13 are respectively located on both sides of the driving seat 41 and abut against the driving seat 41. The two fixed blocks 13 jointly limit the moving path of the driving seat 41, and the fixed blocks 13 partially extend to the pressing plate 9 and partially abut against the pressing plate 9.

[0059] When the mold is opened, the movable mold is driven to move the pressing plate 9 to release the constraint on the driving seat 41; when the mold 2 is closed for injection molding, the pressing plate 9 is used to apply pressure to ensure the correct positioning and shape maintenance between the driving seat 41 and the mold 2, so that the demoulding mechanism 1 can stably contact with the product 3 to improve the quality of the product 3 after injection molding; and when the mold is opened, the pressing plate 9 can be removed from the fixed mold to realize the movement of the driving member 4, thereby realizing the demoulding work of the demoulding mechanism 1, avoiding damage to the mold 2 or the workpiece, and ensuring the safety and efficiency of the demoulding mechanism 1;

[0060] The demoulding mechanism 1 further includes a travel bolt 10, which is fixed on the fixed mold and is located on the side of the driving seat 41 away from the product 3; the travel bolt 10 controls the movement stroke of the driving seat 41 to avoid excessive or insufficient movement of the driving seat 41, and ensures that the entire demoulding mechanism 1 stops at the correct position. By limiting the stroke of the driving seat 41, the travel bolt 10 helps to protect the mold 2 and the product 3 from unnecessary damage or pressure; and by controlling the stroke of the demoulding mechanism 1, it is possible to facilitate the subsequent resetting work of the demoulding mechanism 1, so that the demoulding mechanism 1 is easier to reset to the starting position and prepare for the next production;

[0061] When the mold 2 is in a closed state, the pressure plate 9 and the inclined guide column 6 hold the driving seat 41 against the mold core 21 of the fixed mold. The driving seat 41, the inclined guide column 6 and the pressure plate 9 are in a fixed state, and the driving seat 41 will abut against the outer wall of the mold core 21 of the fixed mold. At this time, the spring 42 abuts in the driving groove 43 and against 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 the movable mold drives the inclined guide column 6 and the pressure plate 9 to move. The movement of the inclined guide column 6 and the pressure plate 9 will release the constraint on the driving seat 41, and at the same time release the constraint on the spring 42. The spring 42 will push the driving seat 41 to move to the side away from the product 3, thereby achieving the purpose of the driving member 4 driving the limiting rod 8 and the forming rod 5 to move. When the driving seat 41 moves to abut against the stroke bolt 10, the driving seat 41 stops moving, and the demolding work is completed.

[0062] The present application also provides a mold device, including a demolding mechanism 1 with a linkage structure as described above; the mold device of the present application utilizes the above-mentioned demolding mechanism 1 to achieve efficient production operations, and can effectively achieve the undercut demolding requirements in multiple directions. No matter how complex the geometric shape of the product 3 or part is, it can flexibly adapt to and complete the demolding process. The demolding mechanism 1 makes it easier to control and adjust the demolding process of the mold device, improves production efficiency, and the demolding mechanism 1 in the mold device can control the demolding position, thereby effectively protecting the mold device itself and the produced product 3 from damage or accidental impact, which helps to extend the service life of the mold and improve the quality stability of the product 3, and enhance the safety and consistency of production operations.

[0063] The implementation principle of the embodiment of the present application is as follows: the present application realizes that a single driving member 4 controls the movement of multiple sliders 7 and the forming rod 5 at the same time through the design of the driving member 4, the forming rod 5, the slider 7 and the limiting rod 8, and can simultaneously handle the demoulding work of the product 3 in multiple directions, and the present application can simplify the number of components and the complexity of the mechanism, thereby reducing the cost;

[0064] When the mold 2 is in a closed state, the pressing plate 9 and the inclined guide column 6 hold the driving seat 41 against the mold core 21 of the fixed mold. The driving seat 41, the inclined guide column 6 and the pressing plate 9 are in a fixed state. The driving seat 41 will abut against the outer wall of the mold core 21 of the fixed mold. At this time, the spring 42 abuts in the driving groove 43 and the mold 2. The spring 42 will compress and store force. During this process, the abutting surface 81 of the limiting rod 8 abuts against the pressing block 11 to ensure the fixed and closed state of the mold 2 and the molding quality of the product 3. At the same time, the restraining inclined surface 82 of the limiting rod 8 abuts against the slider 7 to ensure that the mold 2 completes the injection molding operation in the correct position and state.

[0065] When it is necessary to open the mold, the movable mold is driven to move, and the movable mold drives the inclined guide column 6 and the pressure plate 9 to move. The movement of the inclined guide column 6 and the pressure plate 9 will release the constraint on the driving seat 41 and the constraint on the spring 42. The spring 42 will push the driving seat 41 to move to the side away from the product 3, and the driving seat 41 drives the forming rod 5 and the two limiting rods 8 to move. As the forming rod 5 moves, the forming rod 5 is separated from the product 3 to achieve demoulding. At the same time, the limiting rod 8 withdraws from the abutment state with the pressing block 11, and the abutment surface 81 of the limiting rod 8 abuts against the slider 7 and drives it to move by abutting against the slider 7 to achieve the separation of the slider 7 from the product 3. In this process, as the limiting rod 8 moves, the constraint inclined surface 82 of the limiting rod 8 will follow the movement until it abuts against the mold core 21, and the limiting rod 8 stops moving, completing the separation of the slider 7 from the product 3. At the same time, the driving seat 41 abuts against the stroke bolt 10, and the driving seat 41 stops moving, completing the entire demoulding work.

[0066] 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.
