Description

Technical Field

[0001] This utility model relates to the technical field of fluorine material extrusion molding die head structure, and in particular to a fluorine material extrusion molding die head structure. Background Technology

[0002] A fluorine material extrusion die structure is a core component in the production of various profiles from fluorine materials through extrusion. Its main function is to receive the heated molten fluorine material from the extruder, guide, divert, and shape the melt through pre-designed flow channels that match the shape of the target product, and ensure uniform melt flow through the die's structural design. Finally, the fluorine material melt is extruded into a continuous preform consistent with the shape of the flow channels. With subsequent cooling and shaping processes, a finished fluorine material product that meets the requirements for dimensional accuracy and appearance is obtained. It is the core structure that determines the shape, dimensional stability, and physical properties of fluorine material extrusion products.

[0003] To address the aforementioned issues, existing patents offer solutions. Most existing fluoromaterial extrusion die structures primarily allow material to flow along the central area of ​​the die.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A fluorine material extrusion molding die structure includes an extrusion tube 1, a discharge head 2 is threadedly connected to the front side of the extrusion tube 1, auxiliary components 3 are threadedly connected to the left and right sides of the discharge head 2 and the extrusion tube 1, and a cleaning component 4 is sleeved on the surface of the discharge head 2.

[0029] The auxiliary component 3 includes a connecting pipe 301, a hollow pipe 302 is threadedly connected to the side of the connecting pipe 301 away from the discharge head 2, a threaded pipe 303 is threadedly connected to the side of the hollow pipe 302 away from the discharge head 2, the side of the connecting pipe 301 away from the hollow pipe 302 is connected to the interior of the discharge head 2, and the side of the threaded pipe 303 away from the hollow pipe 302 is connected to the extrusion pipe 1.

[0030] In this embodiment: The extrusion tube 1 serves as the basic conveying component of the die head structure, receiving the heated molten fluorine material from the extruder and providing an initial flow channel for the melt. Simultaneously, it works with the discharge head 2 and auxiliary components 3 to construct the core pathway for melt conveying and shaping. The discharge head 2, threadedly connected to the front of the extrusion tube 1, is a key component for the final shaping and extrusion of the fluorine material melt. Its internal flow channels match the shape of the target product, extruding the melt into a continuous preform of the corresponding shape. It also provides connection points for the auxiliary components 3. The auxiliary components 3, including connecting tubes 301, hollow tubes 302, and threaded tubes 303, primarily function to replenish material to the ends or corners far from the melt center, addressing the problem of insufficient material filling in these areas of existing dies. A cleaning component 4, fitted onto the surface of the discharge head 2, is used to clean residual fluorine material from the outer surface of the discharge head 2. To prevent residual material accumulation from affecting the precision and appearance of subsequent extruded products and to ensure the continuous and stable operation of the die head, a connecting pipe 301 is set up. This is the core connecting and guiding component of the auxiliary component 3. One end is connected to the inside of the discharge head 2, and the other end is threadedly connected to the hollow pipe 302. It can guide part of the melt in the extrusion tube 1 to the hollow pipe 302, providing a channel for subsequent replenishment to the material shortage area. A melt storage and conveying component of the auxiliary component 3 is set up between the connecting pipe 301 and the threaded pipe 303. It receives the melt from the connecting pipe 301 and then conveys it to the threaded pipe 303. A threaded pipe 303 is set up as the connecting and guiding component of the auxiliary component 3. One end is threadedly connected to the hollow pipe 302, and the other end is connected to the extrusion tube 1. It can guide the melt in the hollow pipe 302 back to the extrusion tube 1 or directly to the material shortage area of ​​the die head to achieve precise replenishment. At the same time, the threaded connection method facilitates disassembly and maintenance.

[0031] Specifically, such as Figure 3 As shown, the auxiliary component 3 includes a base frame 401, a top frame 402 is snapped onto the top of the base frame 401, a motor 403 is bolted onto the top of the top frame 402, an adjustment groove 404 is provided on the front side of the top frame 402, a threaded rod 405 is fixedly connected to the bottom of the motor 403, an adjustment block 406 is threadedly connected to the surface of the threaded rod 405 and slidably connected to the adjustment groove 404, and a connecting plate 407 is fixedly connected to the front side of the adjustment block 406.

[0032] Specifically, such as Figure 3 As shown, a scraper 408 is fixedly connected to the top of the inner wall of the connecting plate 407, and the scraper 408 is movably connected to the surface of the discharge head 2.

[0033] Specifically, such as Figure 3 As shown, a collection box 409 is fixedly connected to the front side of the base frame 401. The collection box 409 is made of stainless steel.

[0034] In this embodiment: By setting a base frame 401, the support component of the auxiliary component 3 is snapped into the top frame 402, providing a stable installation foundation for components such as the top frame 402 and the motor 403; the collection box 409 fixed on the front can collect the residual material cleaned by the cleaning component 4, and the pull-out plate 7 at the bottom makes it easy to take out the collected material for subsequent processing. By setting a top frame 402, the support and installation component of the auxiliary component 3 is snapped into the base frame 401, and the motor 403 is bolted to the top. The adjustment groove 404 opened on the front provides sliding space for the adjustment block 406, and the sliding groove 11 opens to slide with the connecting plate 407. The moving block 12 cooperates to ensure the stable movement of the connecting plate 407, thereby ensuring the precise cleaning of the cleaning component 4. A motor 403 is provided as the power source for the auxiliary component 3. A threaded rod 405 is fixedly connected to the bottom. Upon startup, the threaded rod 405 rotates, causing the adjusting block 406 to slide along the adjusting groove 404 via threaded transmission. This, in turn, moves the connecting plate 407 and the scraper 408, providing cleaning power for the cleaning component 4. The adjusting groove 404, located on the front side of the top frame 402, is slidably connected to the adjusting block 406, providing guidance and limiting for the movement of the adjusting block 406, ensuring that the adjusting block 406 drives the connecting plate... The 407 moves stably, preventing the scraper 408 from shifting during cleaning and affecting the cleaning effect. A threaded rod 405 is connected to the bottom of the motor 403 and is driven to rotate by the motor 403. Through threaded engagement with the adjusting block 406, the rotational motion of the motor 403 is converted into linear motion of the adjusting block 406, providing transmission for the movement of the adjusting block 406 and the cleaning component 4. The adjusting block 406 is threadedly connected to the threaded rod 405 and slidably connected to the adjusting groove 404. The front fixed connecting plate 407 can slide along the adjusting groove 404 under the drive of the threaded rod 405, thereby driving the connecting plate 407. 7. The scraper 408 moves to adjust the cleaning position. The connecting plate 407 connects the adjusting block 406 and the scraper 408. The sliding block 12 on the rear side cooperates with the sliding groove 11 of the top frame 402. It can move stably under the action of the adjusting block 406, and at the same time drive the scraper 408 to slide against the surface of the discharge head 2 to complete the cleaning action. The scraper 408 is fixed to the top of the inner wall of the connecting plate 407 and is movably connected to the surface of the discharge head 2. When it moves with the connecting plate 407, it can scrape off the residual fluorine material on the surface of the discharge head 2. It is the core cleaning component of the cleaning assembly 4 and ensures that the outer surface of the discharge head 2 is clean.

[0035] Specifically, such as Figure 2 As shown, a sealing groove 5 is provided on the side of the connecting pipe 301 away from the discharge head 2, and a sealing sleeve 6 that works in conjunction with the sealing groove 5 is fixedly connected to the side of the hollow pipe 302 near the connecting pipe 301.

[0036] Specifically, such as Figure 4 As shown, a pull-out plate 7 is slidably connected to the bottom of the collection box 409, and a buckle 8 is fixedly connected to the bottom of the pull-out plate 7.

[0037] In this embodiment: by setting a sealing groove 5 and a sealing sleeve 6, the sealing sleeve 6 is spliced ​​with the inner wall of the sealing groove 5 to prevent the melt from leaking from the connection between the connecting pipe 301 and the hollow pipe 302, thus ensuring the sealing of the material replenishment channel. By setting a pull plate 7, which is slidably connected to the bottom of the collection box 409, and a bottom fixing block 8, the pull plate 7 can be pulled by the fixing block 8 to facilitate the removal and cleaning of residual materials in the collection box 409, thereby improving the ease of use of the collection box 409. By setting a fixing block 8, which is fixed to the bottom of the pull plate 7, a force point is provided for the operator to pull the pull plate 7, making it easy to quickly pull the pull plate 7 and simplifying the cleaning operation of materials in the collection box 409.

[0038] Specifically, such as Figure 5 As shown, a corrosion-resistant tube 9 is fixedly connected to the inner wall of the hollow tube 302, and a protective sleeve 10 is fitted on the surface of the hollow tube 302.

[0039] Specifically, such as Figure 3 As shown, a sliding groove 11 is provided on the front side of the top frame 402, and a sliding block 12 that cooperates with the sliding groove 11 is fixedly connected to the rear side of the connecting plate 407.

[0040] In this embodiment: by setting a corrosion-resistant tube 9 and fixing it to the inner wall of the hollow tube 302, the chemical corrosion of the fluorine material melt can be resisted, the inner wall of the hollow tube 302 can be prevented from being eroded and damaged by the melt, the service life of the hollow tube 302 can be extended, and the smooth flow of the material supply channel can be ensured. By setting a protective sleeve 10 and covering the surface of the hollow tube 302, the hollow tube 302 can be protected from external collisions, friction and other damage, and the impact of environmental factors on the hollow tube 302 can be reduced, thus extending its service life. By setting a sliding groove 11 and a sliding block 12, the sliding block 12 is movably connected to the inner wall of the sliding groove 11, further ensuring the movement stability of the connecting plate 407 and the scraper 408.

[0041] Specifically, such as Figure 2 , Figure 3 As shown, the surface of the discharge head 2 is provided with a groove 13, and the top frame 402 and the bottom frame 401 are fixedly connected to the opposite side with a protrusion 14 that cooperates with the groove 13.

[0042] Specifically, such as Figure 4 As shown, the front and rear sides of the inner wall of the collection box 409 are provided with sliding grooves 15, and the front and rear sides of the pull plate 7 are fixedly connected with sliders 16 that cooperate with the sliding grooves 15.

[0043] In this embodiment: By setting a groove 13 on the surface of the discharge head 2, which cooperates with the protrusion 14 of the top frame 402 and the bottom frame 401, when the auxiliary component 3 is installed with the discharge head 2, the protrusion 14 is embedded in the groove 13, which plays a role in positioning and fixing the top frame 402 and the bottom frame 401, preventing the auxiliary component 3 from shifting during operation. By setting the protrusion 14, which is fixed on the opposite side of the top frame 402 and the bottom frame 401, and cooperates with the groove 13 of the discharge head 2, the top frame 402 and the bottom frame 401 can be stably fixed on the outside of the discharge head 2 after being embedded in the groove 13, avoiding the displacement of the auxiliary component 3 and the cleaning component 4 during operation, and ensuring the stable operation of the equipment. By setting a sliding groove 15 and a slider 16, the slider 16 is movably connected to the inner wall of the sliding groove 15, ensuring the stable sliding of the pull plate 7, and facilitating the pull-out operation and reset of the pull plate 7.

[0044] Working principle: First, the extrusion tube 1 receives the heated molten fluorine material from the extruder. The melt flows along the extrusion tube 1 to the threaded outlet head 2. Initial shaping is achieved using the pre-designed flow channels inside the outlet head 2 that match the shape of the target product. Simultaneously, the auxiliary components 3 on the left and right sides activate the feeding function. Part of the melt inside the extrusion tube 1 enters the hollow tube 302 through the threaded tube 303. After temporary storage in the hollow tube 302, it is guided by the connecting tube 301 to the ends or corners of the outlet head 2 away from the center of the melt, specifically replenishing the material and solving the problem of insufficient filling in these areas due to long flow channels and high resistance. The connecting tube 301 and the hollow tube 302 are sealed by the sealing groove 5 and the sealing sleeve 6 to ensure no melt leakage. During the extrusion process, if fluorine material remains on the surface of the outlet head 2, the cleaning component 4 can remove it through the top frame 402. Motor 403 drives threaded rod 405 to rotate, causing adjusting block 406 to slide along adjusting groove 404, thereby causing connecting plate 407 to move with scraper 408 against the surface of discharge head 2 to scrape off residual material. The fallen material is collected by stainless steel collection box 409 on the front side of base frame 401. The residual material can be removed by pulling pull plate 7 with buckle 8. During this process, top frame 402 and base frame 401 are stably fixed by protrusion 14 embedded in groove 13 of discharge head 2. Connecting plate 407 slides along sliding groove 11 of top frame 402 through sliding block 12 to ensure stability during cleaning. Corrosion-resistant tube 9 on inner wall of hollow tube 302 resists melt corrosion, and surface protective sleeve 10 protects hollow tube 302, together ensuring continuous and stable operation of die head. Finally, fluorine material melt is extruded through discharge head 2 to form a continuous blank that meets the precision requirements.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
