Technical Field
[0001] This application relates to the field of mold technology, and in particular to a mold and a pressing device. Background Technology
[0002] In the production process of solid silicone molds, the fixed mold typically consists of two templates and a middle plate located between them. During each production cycle, the middle plate must be removed to retrieve the product, and then placed back between the two templates before the next production run. However, if the mold is closed without the middle plate being returned to its original position, the molding parts corresponding to the two templates may be damaged, resulting in equipment loss. Utility Model Content
[0003] This application provides a mold and a pressing device, which improves the safety of the mold.
[0004] To achieve the above objectives, according to a first aspect of this application, a mold is provided, the mold comprising:
[0005] The first and second templates are set relative to each other;
[0006] A limiting component is rotatably disposed on a first template. The limiting component is configured to rotate between a first position and a second position. In the first position, the limiting component can support a second template so that the second template and the first template are spaced apart.
[0007] The third template can be positioned between the first template and the second template, and can push the limiting component to rotate the limiting component to a second position. In the second position, the second template can press the third template onto the first template so that the second template and the first template are molded together.
[0008] Through the above technical solution, this application provides a mold, which includes: a first template, a second template, a limiting component, and a third template. The first template and the second template are arranged opposite to each other. The limiting component is rotatably disposed on the first template and is configured to rotate between a first position and a second position. In the first position, the limiting component can support the second template, so that the second template and the first template are spaced apart. The third template can be disposed between the first template and the second template and can push the limiting component to rotate to the second position. In the second position, the second template can press the third template onto the first template, so that the second template and the first template are closed. This application, through the limiting component, isolates the first template and the second template when the third template is not placed, avoiding damage to the forming parts of the corresponding mold caused by direct mold closing of the two templates; it ensures that the second template will press down and close with the first template only when the third template is correctly positioned, avoiding mold damage caused by forced mold closing when the third template is not correctly placed, and improving the safety of mold closing.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0025] In the production process of solid silicone molds, the fixed mold typically consists of two templates and a middle plate located between them. During each production cycle, the middle plate must be removed to retrieve the product, and then placed back between the two templates before the next production run. However, in actual production, if operators neglect to return the middle plate to its original position and perform the mold closing operation, it will result in severe damage to the molding parts of the mold. This problem not only damages hundreds or thousands of inserts, runner plates, and sprue plates, increasing equipment maintenance time and costs, but may also lead to the risk of product shortages after molding, seriously affecting production efficiency and product quality.
[0026] In view of this, embodiments of this application provide a mold and a molding device, which are intended to overcome at least one of the above-mentioned technical problems.
[0027] Please see Figure 1 As shown, Figure 1 This is an exploded structural diagram of the mold according to an embodiment of this application. This application provides a mold, comprising: a first template 10 and a second template 20 disposed opposite to each other; a limiting component 30 rotatably disposed on the first template 10, the limiting component 30 being configured to rotate between a first position and a second position; in the first position, the limiting component 30 can support the second template 20, thereby spacing the second template 20 from the first template 10; and a third template 40 disposed between the first template 10 and the second template 20, and capable of pushing the limiting component 30 to rotate to the second position; in the second position, the second template 20 can press the third template 40 onto the first template 10, thereby closing the mold between the second template 20 and the first template 10.
[0028] This application provides a mold, typically used for compression molding of products. The mold can be a solid silicone mold for solid silicone. The first template 10, the second template 20, and the third template 40 can be single plate-shaped components or composite plate-shaped components; that is, the first template 10, the second template 20, and the third template 40 can each be a separate plate-shaped component, or they can include multiple connected plate-shaped components. For example, the first template 10 can be a base plate, the second template 20 can be a front panel, and the third template 40 can be a middle plate. Typically, when the mold is closed, the material is placed on the base plate, then the middle plate is placed on the material on the base plate, and finally the front panel moves towards the base plate to close the mold. The material is compressed and molded by heating the closed mold of the front panel and the base plate. After the material is compressed and molded, the base plate and the front panel are separated, and the middle plate is removed, thereby obtaining the compression-molded product from the middle plate. Furthermore, the first template 10 can serve as the basic structure of the mold, remaining fixed to support the entire mold system; the second template 20 is positioned opposite to the first template 10 and can move relative to it to complete the mold opening and closing actions; the third template 40 can be isolated and supported between the first template 10 and the second template 20, and the third template 40 participates in the mold closing and heating molding process. It is understood that the examples in this application do not limit the mold structure, and the mold is not limited to use in solid silicone products.
[0029] Furthermore, to prevent damage to the forming parts of the corresponding mold caused by the direct closing of the two templates when the third template 40 is not placed, this application uses a limiting component 30 to isolate the first template 10 and the second template 20. When the third template 40 is correctly positioned, the limiting component 30 does not affect the closing of the first template 10 and the second template 20. In this application, the limiting component 30 is rotatably mounted on the first template 10 and can rotate between a first position and a second position via a pivot. When the limiting component 30 is in the first position, it indicates that the third template 40 is not placed, and at this time, the limiting component 30 can support the second template 20, thus spacing the second template 20 from the first template 10. When the limiting component 30 is in the second position, it indicates that the third template 40 is correctly positioned, and at this time, the second template 20 can press the third template 40 onto the first template 10, thus closing the mold between the second template 20 and the first template 10.
[0030] Understandably, the rotation of the limiting component 30 between the first and second positions can be achieved through the third template 40. Specifically, during the mold closing process, the third template 40 is placed between the first template 10 and the second template 20. The third template 40, based on its own weight, will push the limiting component 30 to rotate to the second position, indicating that the third template 40 is correctly positioned. The second template 20 can press the third template 40 onto the first template 10 to close the mold with the first template 10. During mold parting, the second template 20 separates from the first template 10, and the third template 40 is removed upwards, which will push the limiting component 30 to rotate to the first position. After the third template 40 is removed, the limiting component 30 maintains the first position. If the second template 20 moves closer to the first template 10 to close the mold, the limiting component 30 can support the second template 20 to keep the second template 20 and the first template 10 spaced apart.
[0031] Through the above technical solution, this application provides a mold designed to improve the safety and reliability of the mold closing process. The mold includes a first template 10, a second template 20, a limiting component 30, and a third template 40, wherein the first template 10 and the second template 20 are arranged opposite to each other. The limiting component 30 is cleverly designed to be rotatably mounted on the first template 10 and can rotate between a first position and a second position. In the first position, the limiting component 30 supports the second template 20, maintaining a distance between it and the first template 10. This ensures that when the third template 40 is not placed, the first template 10 and the second template 20 will not directly close, effectively avoiding potential damage to the mold forming parts. When the third template 40 is correctly placed between the first template 10 and the second template 20, the third template 40 can push the limiting component 30, causing it to rotate to the second position. In this position, the second template 20 can press the third template 40 onto the first template 10, achieving the mold closing operation. Therefore, in this application, the second template 20 will only close with the first template 10 when the third template 40 is correctly positioned, avoiding mold damage caused by forced mold closing due to the third template 40 not being correctly placed. This application not only improves the safety of mold closing but also ensures the accuracy and reliability of mold operation, reduces the risk of damage caused by operational errors, and improves production efficiency and product quality.
[0032] Please see Figures 2 to 6 As shown, Figure 2 This is a front view of the mold according to an embodiment of this application; Figure 3 for Figure 2 A cross-sectional view of the limiting component 30 of the middle mold located at the lower edge AA of the second position; Figure 4 for Figure 3 Enlarged view of point B in the middle; Figure 5 for Figure 2 The lower sectional view of the limiting component 30 of the middle mold in the first position; Figure 6 This is a schematic diagram of the structure of a limiting component 30 according to an embodiment of this application.
[0033] Please see Figures 3 to 5 As shown, in some embodiments, the second template 20 is provided with a first clearance groove 21, and when the limiting component 30 is in the second position, the limiting component 30 can be embedded in the first clearance groove 21.
[0034] In this application, the first clearance groove 21 is provided on the side of the second template 20 facing the first template 10. When the limiting component 30 is in the second position, it indicates that the third template 40 is correctly positioned, and the second template 20 can press the third template 40 onto the first template 10 to close the mold between the second template 20 and the first template 10. At this time, the limiting component 30 does not need to support the second template 20. In order to ensure that the first template 10 and the second template 20 can be completely closed, the first clearance groove 21 is provided on the side of the second template 20 facing the first template 10. This allows part or all of the limiting component 30 to be embedded in the first clearance groove 21, so as to prevent the limiting component 30 from abutting against the second template 20 in the second position and affecting the mold closing between the first template 10 and the second template 20. It is understood that the first clearance groove 21 can be a cube, cuboid, or other shape. Specifically, the size of the first clearance groove 21 needs to be adapted to the portion of the limiting component 30 embedded in the second position.
[0035] Please see Figures 3 to 5 As shown, in some embodiments, the second template 20 is further provided with a step portion 22, which is located outside the first clearance groove 21. When the limiting component 30 is in the first position, the limiting component 30 can abut against the step portion 22.
[0036] In this application, the second template 20 is further provided with a step portion 22. When the limiting component 30 is in the first position, it indicates that the third template 40 is not placed. At this time, the first template 10 and the second template 20 cannot be closed. The step portion 22 then abuts against the limiting component 30 to support the second template 20, thus separating the second template 20 from the first template 10 and preventing mold damage caused by forced mold closing. Furthermore, to ensure complete fit between the second template 20 and the first template 10 when they are closed, the step portion 22 cannot protrude from the plane of the second template 20 facing the first template 10. Therefore, the position where the step portion 22 abuts against the limiting component 30 needs to be recessed inwards based on the plane of the second template 20.
[0037] Understandably, the limiting component 30 rotates towards the inside of the first template 10 from the first position, i.e., the limiting component 30 at point B in the figure rotates clockwise, thus rotating to the second position; it rotates towards the outside of the first template 10 from the second position, i.e., the limiting component 30 at point B in the figure rotates counterclockwise, thus rotating to the first position. It is known that other limiting components 30 can also rotate similarly according to their positions. Furthermore, in the second position, the limiting component 30 does not need to contact and support the second template 20, while in the first position, the limiting component 30 needs to support the second template 20. Therefore, the step portion 22 is set outside the first clearance groove 21, i.e., set at the end of the first clearance groove 21 near the outside of the second template 20, so that when the limiting component 30 rotates from the second position towards the outside of the first template 10 to the first position, it can support the second template 20, thus making the first template 10 and the second template 20 spaced apart.
[0038] Understandably, the step portion 22 includes a horizontal support surface and a guide surface that is perpendicular or inclined to it. The support surface provides a stable contact surface when the limiting component 30 is in the first position, preventing the second template 20 from colliding with the first template 10. The guide surface guides and positions the outer side of the limiting component 30, ensuring that the limiting component 30 can accurately contact the support surface.
[0039] Through the above technical solution, the second template 20 of this application not only has a first clearance groove 21, but also a stepped portion 22. The first clearance groove 21 allows the limiting component 30 to be positioned in the second position, and a portion of the limiting component 30 can be embedded in the first clearance groove 21, enabling the second template 20 to press the third template 40 onto the first template 10, thus closing the mold between the second template 20 and the first template 10. The stepped portion 22 allows the limiting component 30 to be positioned in the first position, and the limiting component 30 can accurately abut against the stepped portion 22, enabling the limiting component 30 to support the second template 20, thus spacing the second template 20 and the first template 10 apart. This further optimizes the function and safety of the mold.
[0040] Please see Figures 3 to 5 As shown, in some embodiments, the first template 10 is provided with a second clearance groove 11, and when the limiting component 30 is in the second position, the limiting component 30 can be embedded in the second clearance groove 11.
[0041] In this application, the second clearance groove 11 is located on the first template 10. Its position and shape are customized according to the specific position and form of the limiting component 30 in the second position to ensure that the limiting component 30 can be fully or partially embedded therein. When the limiting component 30 is in the second position, it can smoothly enter and embed itself in the second clearance groove 11. This allows the limiting component 30 to maintain its stable state without interfering with the normal closure of the first template 10 and the second template 20. Specifically, when it is necessary to open the mold, the limiting component 30 can be easily moved out of the second clearance groove 11 and enter the first position, preventing further closure of the first template 10 and the second template 20. Conversely, when the mold needs to be closed, the limiting component 30 can smoothly embed itself in the second clearance groove 11, providing the necessary support and positioning for the mold closure. It is understood that, based on the position and size of the second clearance groove 11, it can be ensured that the limiting component 30 can be accurately positioned when embedded, thereby enhancing the closure accuracy and stability of the mold.
[0042] Please see Figures 3 to 6 As shown, in some embodiments, the limiting component 30 includes: a base 31 disposed on the first template 10; a drive arm 32 rotatably disposed on the base 31, the drive arm 32 being able to drive the limiting component 30 to rotate between a first position and a second position, in the second position, the drive arm 32 being able to be inserted into a second clearance groove 11; a support arm 33 connected to the drive arm 32, in the second position, the support arm 33 being able to be inserted into a first clearance groove 21, in the first position, the support arm 33 being able to support the second template 20; and a limiting arm 34 connected to the side of the support arm 33 away from the drive arm 32, in the first position, the limiting arm 34 being able to be inserted into the first clearance groove 21; wherein, the drive arm 32, the support arm 33, and the limiting arm 34 surround a bayonet 35, the bayonet 35 being configured to allow the insertion of a third template 40.
[0043] In this application, the base 31 serves as the foundation of the limiting component 30. The base 31 is firmly installed on the first template 10, providing stable support for the entire limiting component 30.
[0044] The drive arm 32 is rotatably mounted on the base 31 and is a key component for the position switching of the limiting assembly 30. It can be rotatably connected to the base 31 via a pivot, allowing the drive arm 32 to smoothly and precisely rotate the entire limiting assembly 30 between the first and second positions. During mold closing, with the limiting assembly 30 in the first position, placing the third template 40 on the drive arm 32 pushes the drive arm 32 towards the second position. In the second position, the drive arm 32 engages with the second clearance groove 11.
[0045] The support arm 33 is connected to the drive arm 32, and its position rotates with the rotation of the drive arm 32. During mold closing, with the limiting component 30 in the first position, placing the third template 40 on the drive arm 32 can push the drive arm 32 towards the second position, thereby causing the support arm 33 to move towards the second position. In the second position, the drive arm 32 engages the second clearance groove 11, and then the second template 20 and the first template 10 close together, with the support arm 33 engaging the first clearance groove 21. In the first position, the support arm 33 can be in a vertical position, that is, perpendicular to the first template 10, to more stably support the second template 20. In the second position, the support arm 33 is inclined towards the first template 10 so that it engages the first clearance groove 21.
[0046] The limiting arm 34 is connected to the support arm 33 on the side away from the drive arm 32. The limiting arm 34 and the drive arm 32 are arranged opposite each other, so that after the third template 40 is placed, the third template 40 is clamped between the limiting arm 34 and the drive arm 32. In the first position, the limiting arm 34 can be embedded in the first clearance groove 21. During the mold parting process, the second template 20 separates from the first template 10 and the third template 40 is taken out. When the third template 40 is taken out upward, it will contact the limiting arm 34. Based on the contact with the limiting arm 34, the drive arm 32 will rotate to the first position. After rotating to the first position and taking out the third template 40, if the third template 40 is not placed in the mold and the second template 20 and the first template 10 are closed, the support arm 33 will abut against the second template 20, that is, the support arm 33 will abut against the step portion 22, so that the second template 20 and the first template 10 are separated. It should be noted that the third template 40 will come into contact with the support arm 33 during the upward removal process, thereby driving the drive arm 32 to rotate towards the first position based on the contact with the support arm 33, and the third template 40 can be removed during the rotation. In addition, the embedding proposed in this application can be partial embedding or complete embedding.
[0047] The bayonet 35 is formed by the drive arm 32, the support arm 33, and the limiting arm 34. The bayonet 35 is designed to insert the third template 40, ensuring that when the third template 40 is correctly positioned, the limiting component 30 can smoothly rotate to the second position, allowing for normal mold closing. Understandably, the shape, size, and position of the bayonet 35 need to be precisely designed based on the specific shape of the third template 40 and the operational requirements of the mold. The design of the bayonet 35 in this application is suitable for product thicknesses of 5mm-11mm, basically covering all types of products.
[0048] Through the above technical solution, the design of the limiting component 30 fully considers the safety during mold operation. The support arm 33 can provide stable support when the limiting component 30 is in the first position, preventing mold damage or personal injury caused by misoperation of the second template 20. The drive arm 32 adjusts its rotation as needed to ensure the correct position change of the limiting component 30. The limiting arm 34 and the drive arm 32 together clamp the third template 40, so that the movement of the third template 40 drives the change of the position state of the limiting component 30. The bayonet 35 provides a stable placement space for the third template 40 and acts as a bridge to drive the rotation of the limiting component 30.
[0049] Please see Figures 3 to 5 As shown, in some embodiments, the inner wall 351 of the bayonet 35 formed by the support arm 33 and the limiting arm 34 is curved. It should be understood that the side of the drive arm 32 facing the bayonet 35 is flat, its main function being to provide a stable support surface for the third template 40. When the limiting component 30 is in the second position, the third template 40 can stably sit on this flat surface. Furthermore, the curved surface of the inner wall 351 of the bayonet 35 formed by the support arm 33 and the limiting arm 34 plays a crucial role in guiding the third template 40 upwards and ensuring that the third template 40 forms a line contact with the inner wall 351 during the removal process, thereby achieving smooth movement. This curved surface design naturally adapts to the movement trajectory of the third template 40 during the removal phase, effectively reducing unnecessary friction and resistance, making the operation smoother. It should be noted that the third template 40 does not remain in contact with the inner wall 351 during the upward removal process; it only makes line contact with the guide surface when it moves to the contact position.
[0050] Please see Figures 3 to 5 As shown, in some embodiments, the first template 10 is further provided with a mounting groove 12, which is located outside the second clearance groove 11 and is used to embed the base 31. It can be understood that the limiting component 30 can rotate from a first position toward the inside of the first template 10 to a second position, at which point the drive arm 32 is embedded in the second clearance groove 11; from the second position, it can rotate to the outside of the first template 10 to the first position; thus, the pivot of the drive arm 32 is located outside the second clearance groove 11, and the base 31 is located outside the second clearance groove 11. To reduce space occupation and prevent the limiting component 30 from protruding too much from the first template 10, thereby affecting the mold closing between the first template 10 and the second template 20, the base 31 is embedded in the mounting groove 12. The portion of the base 31 protruding from the mounting groove 12 may include two oppositely arranged connecting plates. The drive arm 32 is connected between the two connecting plates via a pivot, enabling the drive arm 32 to drive the limiting component 30 to rotate.
[0051] In some embodiments, the volume of the drive arm 32 is smaller than that of the support arm 33. It is understood that to enhance the stability of the limiting component 30 in the first position, the volume of the drive arm 32 is set to be smaller than that of the support arm 33. That is, by increasing the volume and weight of the support arm 33, it is possible to more effectively resist external disturbance forces and prevent the limiting component 30 from accidentally shifting to the second position due to structural instability. Therefore, the volume difference between the drive arm 32 and the support arm 33 helps maintain the stability of the limiting component 30 in the first position, ensuring precise mold operation and safety. Furthermore, the limiting component 30 can be obtained using 3D hollow printing technology, thereby reducing the amount of material used by creating internal cavities without affecting the function of the limiting component 30. The hollow structure not only reduces weight but also helps dissipate heat and reduce stress concentration, thereby extending the service life of the limiting component 30. In mold design, a lightweight limiting component 30 is more likely to maintain the first position, reducing deformation or instability problems caused by excessive weight.
[0052] It should be noted that in some embodiments, there may be multiple limiting components 30, which may surround the first panel or be arranged opposite to it, providing a stable and uniform placement plane for the third template 40. To ensure that the third template 40 can be placed stably and evenly in the mold, this helps to provide a uniformly distributed support force and prevents the third template 40 from tilting or wobbling during placement. Furthermore, the use of multiple limiting components 30 can also enhance the overall stability and durability of the mold.
[0053] Please see Figure 6As shown, in some embodiments, the mold further includes a magnetic component 50 disposed on the first template 10. When the limiting component 30 is in the first position, the magnetic component 50 can connect with the limiting component 30. It is understood that the magnetic component 50 is cleverly positioned on the first template 10. When the limiting component 30 is precisely positioned in the first position, the magnetic component 50 can achieve a seamless connection with it. This design aims to significantly enhance the stability of the limiting component 30 in that position. The magnetic component 50 can be a magnet, which, with its strong magnetic force, can tightly attract the limiting component 30. Whether the limiting component 30 uses traditional metal materials or innovatively uses non-metallic materials containing magnetic additives, it can form a stable and reliable connection with the magnetic component 50. For example, the magnetic component 50 can be placed on the base 31 facing the support arm 33, embedded in the mounting groove 12 along with the base 31. When the limiting component 30 is in the first position, the magnetic component 50 can be tightly connected to the bottom of the support arm 33. This design not only improves the stability of the connection but also ensures that the mold maintains good precision and reliability during long-term use. Furthermore, this application cleverly incorporates 3D die-cutting printing technology. Through this advanced technology, the limiting component 30 can be designed to be lightweight, thus more easily maintaining the first position. This dual guarantee of lightweight design and magnetic connection undoubtedly provides strong support for the stability and durability of the mold. It should be noted that the position of the magnetic component 50 described above is not an absolute limitation. In practical applications, the magnetic component 50 can be adaptively adjusted according to specific needs and mold structure to ensure optimal connection with the limiting component 30 in the first position at a preset position, thereby further consolidating the stability of the first position.
[0054] Please see Figures 1 to 6 As shown, the working process of the mold provided in the embodiments of this application will be described below:
[0055] During the mold closing process, with the limiting component 30 in the first position, the third template 40 is placed on the driving arm 32, that is, the third template 40 is placed into the bayonet 35, which can push the driving arm 32 to move towards the second position, thereby driving the support arm 33 and the limiting arm 34 to move towards the second position, that is, driving the limiting component 30 to move to the second position. The driving arm 32 is embedded in the second clearance groove 11, and then the second template 20 squeezes the third template 40 and closes the mold with the first template 10. The support arm 33 and the limiting arm 34 are embedded in the first clearance groove 21, so that the second template 20 and the first template 10 are closed. Mold closing heating can be performed to mold the material between the first template 10 and the second template 20.
[0056] During the mold separation process, the second template 20 separates from the first template 10, and the third template 40 is taken out. As the third template 40 is taken out upward, it will contact the support arm 33 or the limiting arm 34 in the bayonet 35. Based on the contact with the support arm 33 or the limiting arm 34, the drive arm 32 is driven to rotate to the first position, that is, the limiting component 30 is driven to rotate to the first position. After the third template 40 is taken out, if the third template 40 is not put back in, the second template 20 and the first template 10 are closed. Then the support arm 33 will abut against the second template 20, that is, the support arm 33 will abut against the step part 22, so that the second template 20 and the first template 10 are separated. The product is obtained on the removed third template 40.
[0057] It should be noted that a sensor can also be set to detect whether the support arm 33 is in contact with the step 22. If the support arm 33 is detected to be in contact with the step 22, it means that the third template 40 has not been placed and an alarm can be triggered.
[0058] This application uses a limiting component 30 to ensure that the second template 20 will press down and close with the first template 10 only when the third template 40 is correctly positioned, thus avoiding mold damage caused by forcibly closing the mold when the third template 40 is not correctly positioned and improving the safety of mold closing.
[0059] This application also provides a molding device including a mold, so the molding device can have all the technical features and beneficial effects of the above-mentioned mold, which will not be repeated here.
