Description

Technical Field

[0001] The present application relates to the technical field of thermoplastic elastomer production equipment, and in particular to a temperature-controlled thermoplastic elastomer molding device. Background Art

[0002] Thermoplastic elastomers (TPEs), materials that combine the processing properties of plastics with the physical properties of rubber, are widely used in a variety of fields, including automotive, electronics, medical, and toys. During the molding process of TPEs, molds are typically used to shape them to obtain products with specific shapes and sizes.

[0003] The temperature-controlled thermoplastic elastomer molding device is a device specially used for the molding of thermoplastic elastomer materials. It precisely controls the heating and cooling processes to allow the material to be molded within a specific temperature range, thereby ensuring that the product has excellent physical properties and appearance quality.

[0004] A molding mold typically consists of an upper mold and a lower mold, with the upper mold nested inside the lower mold. Because the lower mold is typically U-shaped and has a narrow opening, this structure can easily cause the upper mold to adhere to the thermoplastic elastomer and remain inside the lower mold during mold separation, making it difficult to open the mold. This not only affects production efficiency but can also damage the mold and the finished product, increasing production costs.

[0005] Therefore, the present application provides a temperature-controlled thermoplastic elastomer molding device to solve the above problems. Utility Model Content

[0006] The present application provides a temperature-controlled thermoplastic elastomer molding device, which aims to solve the problem of the existing molding mold mentioned in the background art that the upper mold is easily adhered to the inside of the lower mold during the mold opening process, making it difficult to open the mold.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solution: a temperature-controlled thermoplastic elastomer molding device, comprising: a lower mold, a mold cavity provided on the lower mold, and an upper mold provided on the lower mold;

[0008] Unlike existing temperature-controlled thermoplastic elastomer molding devices, the upper mold is equipped with a removal structure for removing the upper mold from the lower mold. The removal structure includes a fixed plate symmetrically fixed to the end of the upper mold away from the lower mold, and a connecting plate fixed between the two fixed plates for hand-holding. By providing the removal structure on the upper mold, the operator only needs to grasp the connecting plate and apply appropriate force to easily remove the upper mold from the lower mold, greatly simplifying the removal operation and improving production efficiency. The presence of the removal structure avoids damage caused by directly prying the upper mold in traditional mold opening methods, extending the mold life and reducing maintenance costs.

[0009] To facilitate the attachment of the upper die to the lower die, a fixing structure is provided on the lower die to secure the upper die. This fixing structure incorporates a mechanical locking principle to ensure the upper die remains secure during processing while also allowing the operator to easily unlock and remove the upper die from the lower die when needed.

[0010] Preferably, in order to increase the extrusion force of the connecting plate on the upper mold, the connecting plate is arc-shaped. By optimizing the structural form, the extrusion force of the connecting plate on the upper mold is enhanced, thereby ensuring that the upper mold can fit more tightly and stably on the lower mold during processing. When the operator grasps the connecting plate to remove or fix the upper mold, the arc-shaped design allows the connecting plate to fit the contour of the hand more naturally, providing a comfortable grip. At the same time, when force is applied, the arc shape can more effectively transfer the force to the upper mold, forming a more uniform and powerful extrusion force, thereby ensuring the stability of the upper mold.

[0011] Preferably, the fixing structure includes a movable plate plugged into the lower mold and a threaded rod plugged into the movable plate and connected to the connecting plate, and the top of the threaded rod is fixedly connected to a plum blossom plate. The introduction of the fixing structure significantly enhances the connection stability between the upper mold and the lower mold, and reduces product deformation or quality problems caused by mold loosening during processing. The upper mold can be fixed or unlocked through a simple rotation operation, which greatly improves operating efficiency and reduces waiting time during the production process. The stable fixing structure reduces the safety hazards caused by loosening of the mold during processing and improves the safety of the production site.

[0012] Preferably, to facilitate installation or removal of the movable panel at a specific location, the lower mold is provided with a through slot for the movable panel to be inserted. This slot design makes installation of the movable panel quick and easy; the operator simply aligns the movable panel with the slot and gently pushes it in, without the need for additional tools or equipment. If the movable panel needs to be replaced due to wear or damage, the operator can simply remove it from the slot and replace it, without disassembling or overhauling the entire mold system.

[0013] Preferably, to enhance the stability of the threaded rod locking the connecting plate, a groove for the threaded rod to insert into is defined at the end of the connecting plate distal from the upper die. This groove provides a secure insertion point for the threaded rod, enhancing the locking effect through physical engagement, and effectively preventing the connecting plate from loosening or falling off during processing. This secure locking structure reduces wear and damage caused by loosening, thereby extending the service life of the connecting plate and threaded rod.

[0014] Preferably, to prevent the upper die from shifting within the lower die, the lower die is provided with a limiting groove, within which a limiting block fixedly connected to the upper die is disposed. The combination of the limiting groove and the limiting block completely eliminates the possibility of displacement of the upper die within the lower die through physical restraint, ensuring the stability and reliability of the machining process.

[0015] Preferably, to facilitate handling of the forming mold, circular rings are symmetrically fixedly connected to both sides of the lower mold. To facilitate handling, the circular rings are typically designed to be compatible with common handling tools (such as rings and ropes). This allows the operator to quickly and stably transport the entire mold system by simply threading the hook or rope of the handling tool through the circular rings.

[0016] This application utilizes the design of the removal structure, so the operator can easily grasp the connecting plate and apply force to achieve rapid separation of the upper and lower molds, convenient removal, significantly improve production efficiency, and at the same time ensure the stability and reusability of the mold.

[0017] This application utilizes a fixed structure to ensure a tight fit between the upper and lower molds during the curing process, preventing material spillage or deformation and ensuring product quality. The plum blossom plate design facilitates the rotation of the threaded rod, while the combination of the limit groove and the limit block further enhances the stability of the mold.

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] This embodiment provides a temperature-controlled thermoplastic elastomer molding device, such as Figure 1-4 As shown, the mold includes a lower mold 1, a mold cavity 2 opened on the lower mold 1, and an upper mold 3 arranged on the lower mold 1;

[0026] Unlike existing temperature-controlled thermoplastic elastomer molding devices, the upper mold 3 is equipped with a removal mechanism 4 for removing the upper mold 3 from the lower mold 1. This removal mechanism 4 comprises a fixed plate 41 symmetrically fixed to the end of the upper mold 3 facing away from the lower mold 1, and a hand-held connecting plate 42 fixed between the two fixing plates 41. By providing the removal mechanism 4 on the upper mold 3, the operator can easily remove the upper mold 3 from the lower mold 1 by simply grasping the connecting plate 42 and applying appropriate force, greatly simplifying the removal operation and improving production efficiency. The presence of the removal mechanism 4 avoids damage caused by directly prying the upper mold 3 in traditional mold opening methods, extending the mold life and reducing maintenance costs. In the molding device, the material to be processed is first placed in the mold cavity 2 of the lower mold 1, and then the upper mold 3 and lower mold 1 are tightly closed. After processing is completed, the operator grasps the connecting plate 42 in the removal mechanism 4 and uses the lever principle to easily lift and remove the upper mold 3 from the lower mold 1. The entire removal process is smooth, fast, and safe, effectively improving production efficiency and operational safety.

[0027] To facilitate the attachment of the upper mold 3 to the lower mold 1, a fixing structure 5 is provided on the lower mold 1 for securing the upper mold 3. The fixing structure 5 comprises a movable plate 51 inserted into the lower mold 1 and a threaded rod 52 inserted into the movable plate 51 and connected to the connecting plate 42. The top of the threaded rod 52 is fixedly connected to a plum blossom plate 521. This fixing structure 5 incorporates a mechanical locking principle to ensure that the upper mold 3 remains stable during processing, while also facilitating the operator's ability to easily unlock and remove the upper mold 3 from the lower mold 1 when needed. The introduction of the fixing structure 5 significantly enhances the stability of the connection between the upper mold 3 and the lower mold 1, reducing product deformation or quality issues caused by mold loosening during processing. The upper mold 3 can be fixed or unlocked with a simple rotation, greatly improving operational efficiency and reducing waiting time during the production process. The stable fixing structure 5 reduces safety hazards caused by mold loosening during processing and improves safety at the production site. Before processing begins, the operator first inserts the movable plate 51 onto the lower die 1 and places the upper die 3 on top of it. The operator then rotates the plum blossom plate 521, driving the threaded rod 52 downward until the other end of the threaded rod 52 makes firm contact with the upper die 3 (or its connected component) and generates sufficient locking force. At this point, the upper die 3 is securely fastened to the lower die 1, ready for processing. Once processing is complete, the operator rotates the plum blossom plate 521 again to release the locking force of the threaded rod 52 and easily remove the upper die 3 from the lower die 1. The entire fastening and unlocking process is simple and quick, ensuring efficient and safe production.

[0028] Specifically, to enhance the squeezing force exerted by the connecting plate 42 on the upper mold 3, the connecting plate 42 is designed to be curved. This structural optimization enhances the squeezing force exerted by the connecting plate 42 on the upper mold 3, ensuring a tighter and more stable fit between the upper mold 3 and the lower mold 1 during processing. When the operator grasps the connecting plate 42 to remove or secure the upper mold 3, the curved shape allows it to fit more naturally with the hand, providing a comfortable grip. Furthermore, when applying force, the curved shape more effectively transfers the force to the upper mold 3, creating a more uniform and powerful squeezing force, thereby ensuring the stability of the upper mold 3. During processing, when the operator needs to secure the upper mold 3, they grasp the curved connecting plate 42 and apply downward force. Due to the curved shape of the connecting plate 42, this force is more evenly distributed on the upper mold 3, transforming into a strong squeezing force. This squeezing force ensures a tighter contact between the upper mold 3 and the lower mold 1, reducing the possibility of play and looseness. At the same time, when it is necessary to remove the upper mold 3, the operator can also easily lift and remove the upper mold 3 from the lower mold 1 by holding the connecting plate 42 and applying upward force. Throughout the entire process, the arc-shaped connecting plate 42 plays a key role, ensuring the smoothness and safety of the operation.

[0029] More specifically, to facilitate the installation or removal of the movable panel 51 at a specific location, the lower mold 1 is provided with a through slot 11 for the movable panel 51 to plug into. The opening direction of the through slot 11 aligns with the insertion direction of the movable panel 51, allowing the operator to smoothly insert or remove the movable panel 51. The design of the through slot 11 makes installation of the movable panel 51 simple and quick. The operator simply aligns the movable panel 51 with the through slot 11 and gently pushes it in, without the need for additional tools or equipment. If the movable panel 51 needs to be replaced due to wear or damage, the operator can easily remove it from the through slot 11 and replace it without disassembling or overhauling the entire mold system. To install the movable panel 51, the operator first aligns it with the through slot 11 on the lower mold 1 and gently pushes it in along the direction of the through slot 11. As the movable panel 51 is inserted deeper, its side walls will fit tightly against the side walls of the through slot 11. To remove the movable panel 51, the operator simply pulls it out of the through slot 11. The entire installation and disassembly process is simple, fast, safe and reliable.

[0030] Furthermore, to enhance the stability of the threaded rod 52 locking the connecting plate 42, a groove 421 is defined on the end of the connecting plate 42 facing away from the upper die 3 for insertion of the threaded rod 52. The opening direction of the groove 421 generally aligns with the insertion direction of the threaded rod 52, and its depth and width are sufficient to accommodate the inserted portion of the threaded rod 52, preventing slippage or misalignment during rotation. The design of the groove 421 provides a secure insertion point for the threaded rod 52, enhancing the locking effect through the interlocking physical structure, effectively preventing the connecting plate 42 from loosening or falling off during processing. This secure locking structure reduces wear and damage caused by loosening, thereby extending the service life of the connecting plate 42 and the threaded rod 52. To secure the upper die 3, the operator first installs the movable plate 51 into the through-slot 11 of the lower die 1 and inserts the threaded rod 52 through the reserved hole in the movable plate 51. The operator then aligns the inserted portion of the threaded rod 52 with the groove 421 on the connecting plate 42 and slowly screws it in. As the threaded rod 52 gradually penetrates deeper, its head or a specific portion will completely embed in the groove 421, forming a secure locking structure. At this point, the connecting plate 42 is tightly connected to the movable plate 51 via the threaded rod 52, thereby firmly securing the upper mold 3 to the lower mold 1. To unlock, the operator simply rotates the threaded rod 52 in the opposite direction to pull it out of the groove 421, easily removing the connecting plate 42 and upper mold 3 from the lower mold 1.

[0031] Furthermore, in order to prevent the upper mold 3 from being displaced in the lower mold 1, a limiting groove 12 is provided on the lower mold 1, and a limiting block 31 fixedly connected to the upper mold 3 is provided inside the limiting groove 12. The opening direction of the limiting groove 12 is usually consistent with the insertion direction of the upper mold 3, so that the limiting block 31 can slide in and be positioned smoothly. The limiting block 31 is firmly mounted on the bottom or side of the upper mold 3 by welding, bolt connection or other reliable fixing methods to ensure that it will not fall off or loosen during the processing. The use of the limiting groove 12 and the limiting block 31 in conjunction with each other completely eliminates the possibility of displacement of the upper mold 3 in the lower mold 1 by physical limiting, thereby ensuring the stability and reliability of the processing process. Before the processing starts, the operator first aligns the upper mold 3 with the opening of the lower mold 1 and slowly pushes it in. As the upper mold 3 gradually goes deeper, the limiting block 31 at its bottom will automatically slide into the limiting groove 12 on the lower mold 1 and be blocked by the side wall of the limiting groove 12. At this point, a stable limiting structure is formed between the limiting block 31 and the limiting groove 12, limiting any displacement of the upper die 3 within the lower die 1. During the machining process, regardless of any external forces or vibrations, the upper die 3 will maintain a stable position, thus ensuring smooth machining and stable and reliable product quality.

[0032] Specifically, to facilitate the handling of the temperature-controlled thermoplastic elastomer molding device, rings 6 are symmetrically fixedly attached to both sides of the lower mold 1. To facilitate handling, the rings 6 are typically designed to be compatible with common handling tools (such as rings and ropes). This allows the operator to quickly and stably transport the entire mold system by simply threading the hooks or ropes of the handling tools through the rings 6. To transport the molding mold, the operator first confirms that the rings 6 are securely attached to both sides of the lower mold 1. They then select a suitable handling tool (such as a crane, forklift, or rope) and thread the hooks or ropes through the rings 6. The operator then controls the handling tool to move the entire mold system until it is positioned at the desired location. Throughout the entire handling process, the rings 6 play a critical role in load-bearing and stabilizing the mold, ensuring safe and stable handling.

[0033] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
