Description

Technical Field

[0001] The utility model relates to the field of extrusion dies, in particular to a heat insulation strip extrusion die. Background Art

[0002] The heat insulation strip extrusion die is the core tool in the production of heat insulation strips. It is exquisitely designed and crucial. The raw material enters the die through an extruder, is plasticized into the required shape through a specific runner and cavity, and then forms after cooling. The design of this die needs to comprehensively consider the fluidity of the raw material, the compression ratio, and the cooling method to ensure the quality of the heat insulation strip. This kind of die is mainly used in the production of heat insulation strips required for aluminum alloy doors and windows, etc. These heat insulation strips are widely used in many fields such as construction and automobiles. In short, the heat insulation strip extrusion die is an important tool to ensure the quality and performance of heat insulation strip products, and plays a crucial supporting role in modern industrial and building heat insulation technologies.

[0003] The existing water-cooling plate equipped with the heat insulation strip extrusion die can quickly cool the extruded heat insulation strip. However, currently, the water channel design inside the water-cooling plate is a connected structure, making the cooling effect of the entire water-cooling plate uniform. Facing the current diverse heat insulation strip processing technologies, this single water channel structure limits its adaptability to different processing requirements, thus affecting the diversity and flexibility of heat insulation strip processing. Therefore, it is necessary to improve the water channel design to enhance its adaptability to various processing technologies. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a heat insulation strip extrusion die to solve the technical problem that the single water channel structure inside the water-cooling plate reduces the adaptability of the heat insulation strip processing technology diversity.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a heat insulation strip extrusion die, including a die body, a water-cooling component is arranged on one side of the die body, the water-cooling component includes a lower water-cooling plate and an upper water-cooling plate, multiple groups of die grooves are opened on the surfaces of the die body, the lower water-cooling plate, and the upper water-cooling plate, a cold water pipe is arranged on the outer side of each group of die grooves, water inlets are opened on the top surfaces of the lower water-cooling plate and the upper water-cooling plate, water outlets are opened on one side of the bottom surfaces of the lower water-cooling plate and the upper water-cooling plate, a shunt pipe is arranged between adjacent cold water pipes, a second plug hole is opened on the shunt pipe, a first plug hole is opened on the cold water pipe, and a limit plug is threadedly connected inside the first plug hole and the second plug hole.

[0006] By adopting the above technical solution, when a certain group of die grooves is not used, by screwing the limit plug to close the corresponding first plug hole and second plug hole, the flow path of the coolant can be precisely controlled to bypass the cold water pipe corresponding to the die groove that does not need to be cooled.

[0007] Furthermore, a set of the mold grooves is provided with multiple individual mold grooves, and multiple sets of the mold grooves are arranged in equidistant linear array.

[0008] By adopting the above technical solution, this means that multiple extrusion operations of heat insulation strips can be carried out simultaneously within the same set of mold grooves. This setting greatly improves the production efficiency because it can process multiple heat insulation strips in parallel, reducing the waiting time and the number of equipment switches during production.

[0009] Furthermore, the limit plug is used to block the cold water pipe and the shunt pipe.

[0010] By adopting the above technical solution, this provides precise control over the coolant flow path. By blocking specific pipes, it is possible to flexibly adjust which mold grooves receive the coolant, thus meeting different cooling requirements.

[0011] Furthermore, rounded corners are formed at the bending corners of the cold water pipe and the shunt pipe.

[0012] By adopting the above technical solution, the rounded corners can reduce the resistance of the fluid at the bending corners, making the coolant flow more smoothly. The rounded corner design reduces the sudden change in flow velocity and the formation of eddies, thus reducing energy loss.

[0013] Furthermore, the water inlet and the water outlet are connected to an external coolant storage device through a water delivery pipe and a liquid pump.

[0014] By adopting the above technical solution, this ensures the continuous supply and recycling of the coolant. This setting can ensure that the water-cooling component continuously and effectively cools the mold, thus maintaining stable temperature conditions during the extrusion process.

[0015] Furthermore, mounting holes are provided on the mold body, the lower water-cooling plate and the upper water-cooling plate, which are the connection penetration points for the mounting bolts to penetrate the mold body, the lower water-cooling plate and the upper water-cooling plate.

[0016] By adopting the above technical solution, the mounting holes facilitate the use of bolts to tightly connect them together. This connection method ensures the stability and rigidity of the mold structure, can withstand various forces and heats during the extrusion process, thus maintaining the accuracy and service life of the mold.

[0017] Furthermore, limit posts are provided on both sides of the surface of the mold body, and the limit posts are inserted into the holes on the surface of the lower water-cooling plate.

[0018] By adopting the above technical solution, it can ensure the precise positioning between the mold body and the lower water-cooling plate. The limit posts provide stable support and positioning points, preventing the mold from shifting or misaligning during use, thus ensuring the accuracy and quality of the extruded products.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] With the water-cooling component of the present utility model, when a certain set of die slots is not needed, the operator can simply turn the limit plug to close the corresponding first plug port and second plug port. This setting enables the coolant to bypass the section of the cold water pipe that is not in use, thereby optimizing the flow path of the coolant. This flexible coolant flow control method not only makes the water-cooling component more adaptable to diverse heat insulation strip processing technologies but also greatly improves the practicality and energy efficiency of the water-cooling component. This innovative setting effectively addresses different processing requirements and provides a more efficient and flexible solution for the production of heat insulation strips.

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0027] The embodiments of the present utility model will be described below according to its overall structure.

[0028] Embodiment 1:

[0029] A heat insulation strip extrusion die, as Figures 1-4As shown in the figure, it includes a mold body 1. A water cooling component 3 is arranged on one side of the mold body 1. The water cooling component 3 includes a lower water cooling plate 301 and an upper water cooling plate 302. Multiple groups of mold grooves 2 are opened on the surfaces of the mold body 1, the lower water cooling plate 301 and the upper water cooling plate 302. A cold water pipe 305 is arranged on the outside of each group of mold grooves 2. Water inlets 303 are opened on the top surfaces of the lower water cooling plate 301 and the upper water cooling plate 302, and water outlets 304 are opened on the ground side of the lower water cooling plate 301 and the upper water cooling plate 302. A shunt pipe 306 is arranged between adjacent cold water pipes 305. A second plug hole 308 is opened on the shunt pipe 306, and a first plug hole 307 is opened on the cold water pipe 305. A limit plug 309 is screwed inside the first plug hole 307 and the second plug hole 308. When a certain group of mold grooves 2 is not in use, by turning the limit plug 309 to close the corresponding first plug hole 307 and second plug hole 308, the flow path of the coolant can be precisely controlled to bypass the cold water pipe 305 corresponding to the mold grooves 2 that do not need to be cooled. At the same time, this setting enables the water cooling component 3 to more flexibly adapt to different heat insulation strip processing technologies. Because different processing technologies may require cooling different mold grooves 2, by adjusting the limit plug 309, the control of the coolant flow can be easily achieved, thereby improving the practicability of the water cooling component 3, meeting different processing requirements, and optimizing production efficiency and product quality.

[0030] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , one group of mold grooves 2 is provided with multiple single mold grooves, and multiple groups of mold grooves 2 are arranged in an equidistant linear manner. This means that multiple heat insulation strips can be extruded simultaneously within the same group of mold grooves 2. This setting greatly improves production efficiency because it can process multiple heat insulation strips in parallel, reducing the waiting time and the number of equipment switches during production. At the same time, multiple groups of mold grooves 2 are arranged in an equidistant linear manner. This layout not only ensures the structural compactness of the mold but also facilitates operation and maintenance. The equidistant arrangement ensures that each mold groove 2 can obtain a uniform cooling effect, and the linear layout simplifies the design and installation of the cooling system.

[0031] Refer to Figure 1 , Figure 3 , Figure 4, The limit plug 309 is used to block the cold water pipe 305 and the shunt pipe 306, which provides precise control over the coolant flow path. By blocking specific pipes, it is possible to flexibly adjust which die slots 2 receive coolant, thus meeting different cooling requirements. At the same time, this setting also improves the energy efficiency and flexibility of the water-cooling component 3. When certain die slots 2 do not require cooling, by closing the corresponding pipes, coolant waste can be avoided and energy consumption can be reduced. In addition, this modular setting makes the water-cooling system easier to maintain and repair because a certain part can be individually shut down without affecting the operation of other parts.

[0032] Refer to Figure 3 、 Figure 4 , Fillets are formed at the bends of the cold water pipe 305 and the shunt pipe 306. The fillets can reduce the resistance of the fluid at the bends, making the coolant flow more smoothly. The fillet design reduces the sudden change in flow velocity and the formation of vortices, thereby reducing energy loss. At the same time, the fillets can also enhance the structural strength of the pipe, reduce stress concentration, and improve the service life of the pipe. In addition, the fillets also help reduce corrosion and wear inside the pipe because the smooth bends reduce the impact of the fluid on the pipe wall.

[0033] Refer to Figure 3 、 Figure 4 , The water inlet 303 and the water outlet 304 are connected to an external coolant storage device through a water pipe and a liquid pump. This ensures the continuous supply and recycling of the coolant. This setting can ensure that the water-cooling component 3 continuously and effectively cools the die, thus maintaining stable temperature conditions during the extrusion process. At the same time, this setting also facilitates the monitoring and management of the coolant. By being connected to an external storage device, it is convenient to monitor the quantity, temperature, and cleanliness of the coolant and replace or clean it when necessary. This connectivity not only improves production efficiency but also extends the service life of the water-cooling component 3 and reduces maintenance costs.

[0034] Embodiment Two:

[0035] Refer to Figure 1 、 Figure 2 , Mounting holes 4 are provided on the die body 1, the lower water-cooling plate 301, and the upper water-cooling plate 302. They are the penetration points for the mounting bolts to connect the die body 1, the lower water-cooling plate 301, and the upper water-cooling plate 302. The mounting holes 4 facilitate the use of bolts to tightly connect them together. This connection method ensures the stability and rigidity of the die structure, can withstand various forces and heats during the extrusion process, thus maintaining the accuracy and service life of the die. At the same time, the design of the mounting holes 4 also makes the assembly and disassembly of the die simple and fast, facilitating maintenance and replacement of components. In addition, the bolt connection also has adjustability, and the die can be finely adjusted according to needs to meet different processing requirements.

[0036] Refer toFigure 1 , Figure 2 , on both sides of the surface of the mold body 1, limiting columns 5 are provided. The limiting columns 5 are inserted into the holes on the surface of the lower water-cooling plate, which can ensure the precise positioning between the mold body 1 and the lower water-cooling plate 301. The limiting columns 5 provide stable support and positioning points, preventing the mold from shifting or misaligning during use, thus ensuring the accuracy and quality of the extruded product. At the same time, the limiting columns 5 also enhance the overall structural strength of the mold. Through the insertion with the lower water-cooling plate 301, a more stable structural system is formed, which can withstand greater extrusion pressure and heat. This setting not only improves the stability and durability of the mold, but also reduces the risk of deformation and damage that may occur during the use of the mold.

[0037] The implementation principle of the present utility model is as follows: First, the cooling liquid enters the cold water pipe 305 between the lower water-cooling plate 301 and the upper water-cooling plate 302 from the water inlet 303. Using the form of heat conduction, it absorbs the heat of the heat insulation strip inside the mold groove 2, causing the extruded heat insulation strip to be quickly cooled, and completing the extrusion operation of the heat insulation strip. When one set of mold grooves 2 is not used, by turning the limiting plug 309, the corresponding first plug port 307 and second plug port 308 are closed or opened, causing the cooling liquid to bypass this section of the cold water pipe 305, which is beneficial to making the water-cooling component 3 more adaptable to the processing technology of diverse heat insulation strips and improving the practicability of the water-cooling component 3.

[0038] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here.

[0039] Although the embodiments of the present utility model have been shown and described, this specific embodiment is only an explanation of the present utility model, and it is not a limitation of the utility model. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions, and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
