Description

Technical Field

[0001] This invention relates to the field of extrusion die technology, specifically to a dry setting and setting strip adjustment device for an extrusion die. Background Technology

[0002] Extrusion dies, also known as extrusion molding heads, are a type of mold used to produce continuous-shaped plastic products. They are widely used in the processing of pipes, rods, monofilaments, sheets, films, wire and cable sheathing, and profiles. The principle is that solid plastic is melted and plasticized under heating and pressure from the rotating screw of the extruder, and then passed through a die of a specific shape to form a continuous plastic product with a cross-section identical to the die shape. The die is the final thermo-pressing device in the entire plastic extrusion process, and its geometry, structure, dimensions, temperature, and pressure directly determine the success or failure of the product processing.

[0003] See appendix Figure 1 Currently, during the debugging and production of special-shaped profiles, due to their small size and thin wall thickness, it is difficult for them to enter the cavity of the dry setting and cooling system. Operators must remove the dry setting cover plate and side setting strips one by one, and then reinstall the side setting strips and cover plate after the profile enters the dry setting cavity. This is very inconvenient in actual production, and repeated disassembly and reassembly can also damage the positioning keys of the dry setting, affecting the service life of the dry setting. Therefore, this invention proposes a dry setting strip adjustment device for extrusion dies to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a solution to the problems raised in the background art.

[0005] This invention is achieved through the following technical solution:

[0006] This invention relates to a dry shaping strip adjustment device for an extrusion die, comprising shaping strip one, shaping strip two, shaping strip three, shaping strip four, an adjusting screw, a fixing block, and a cover plate;

[0007] The second shaping strip has a threaded hole 1 that matches the adjusting screw, the fixed block has a threaded hole 2, the fourth shaping strip has a threaded hole 3 that matches the threaded hole 2, the first shaping strip, the second shaping strip, and the third shaping strip all have waist-shaped grooves, the third shaping strip has a sliding groove, the third shaping strip can move along the extension direction of the sliding groove on the fourth shaping strip, and the cover plate and the fourth shaping strip have threaded holes 4;

[0008] The shaping strip one, shaping strip two, and shaping strip three are fixed together as a whole by bolt one, and the shaping strip one, shaping strip two, shaping strip three, and shaping strip four are fixed by bolt two. The adjusting screw passes through the fixing block and is fixedly connected to shaping strip two.

[0009] Preferably, the bolt two passes through the threaded hole four on the cover plate, the waist-shaped groove, and the threaded hole four on the shaping strip four in sequence to fix the cover plate, shaping strip one, shaping strip two, shaping strip three, and shaping strip four.

[0010] Preferably, the second bolt passes through the waist-shaped grooves on the first, second, and third shaping strips in sequence.

[0011] Preferably, by loosening the second bolt and pulling the adjusting screw outward, the first shaping strip, the second shaping strip, and the third shaping strip are moved outward as a whole, thereby expanding the dry shaping cavity.

[0012] Preferably, it also includes a profile, which is housed inside the dry-forming cavity.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the production of profiles, operators loosen bolt two and pull the adjusting screw outwards to move shaping strips one, two, and three outwards as a whole, thus expanding the dry shaping cavity and ensuring that the profile can enter the cavity quickly and accurately. After the profile enters the cavity, the adjusting screw is pushed inwards to move shaping strips one, two, and three inwards as a whole until the expanded cavity is restored. Finally, bolt two is tightened. This adjustment solves the problem of profiles being difficult to enter the dry shaping and cooling system cavity during production. It is designed to be easy to operate and not too complicated, facilitating processing. Attached Figure Description

[0028] Please see Figures 2 to 7This invention provides a technical solution: a dry shaping strip adjustment device for an extrusion die, comprising a first shaping strip 1, a second shaping strip 2, a third shaping strip 3, a fourth shaping strip 4, an adjusting screw 5, a fixing block 6, and a cover plate 7; the second shaping strip 2 has a threaded hole 8 matching the adjusting screw 5, the fixing block 6 has a threaded hole 9, and the fourth shaping strip 4 has a threaded hole 10 matching the threaded hole 9; the first shaping strip 1, the second shaping strip 2, and the third shaping strip 3 all have... The shape has a waist-shaped groove 11, and a sliding groove 12 is provided on the shaping strip 3. The shaping strip 3 can move along the extension direction of the sliding groove 12 on the shaping strip 4. The cover plate 7 and the shaping strip 4 are provided with threaded holes 4 13. The shaping strip 1, shaping strip 2 and shaping strip 3 are fixed into a whole by bolt 1 14. The shaping strip 1, shaping strip 2, shaping strip 3 and shaping strip 4 are fixed by bolt 2 15. The adjusting screw 5 passes through the fixing block 6 and is fixedly connected to the shaping strip 2.

[0029] In this embodiment, shaping strip 1, shaping strip 2, and shaping strip 3 are fixed together as a whole with bolt 14. Bolt 215 is passed through threaded hole 413 on cover plate 7, waist groove 11 on shaping strip 1, shaping strip 2, and shaping strip 3 in sequence, and fixed to shaping strip 4. Fixing block 6 is installed on threaded hole 29 on shaping strip 4 with bolt 3. Adjusting screw 5 is passed through fixing block 6 and installed at threaded hole 8 on shaping strip 2. The installation is then completed. After shaping strip 1, shaping strip 2, and shaping strip 3 are fixed together with shaping strip 4 by bolt 215, the gap cavity formed at the connection is the dry shaping cavity.

[0030] In the production of profile 16, the operator can loosen bolt 2 15 and pull the adjusting screw 5 outward to move the shaping strip 1, shaping strip 2, and shaping strip 3 outward as a whole, thereby expanding the shaping cavity and ensuring that the profile 16 can enter the cavity quickly and accurately. After the profile 16 enters the cavity, the adjusting screw 5 is pushed inward to move the shaping strip 1, shaping strip 2, and shaping strip 3 inward as a whole until the expanded cavity is restored. Finally, bolt 2 15 is tightened.

[0031] The above adjustments solve the problem of profile 16 being difficult to enter the dry setting and cooling system cavity during the production process. While ensuring ease of operation, the process should not be too complicated and should be easy to process.

[0032] For further details, please refer to Figure 3 Bolt 2 15 passes through threaded hole 4 13 on cover plate 7, waist groove 11 and threaded hole 4 13 on shaping strip 4 to fix cover plate 7, shaping strip 1, shaping strip 2, shaping strip 3 and shaping strip 4.

[0033] For further details, please refer to Figure 3 Bolt 215 passes through the waist groove 11 on shaping strip 1, shaping strip 2 and shaping strip 3 in sequence.

[0034] In this embodiment, shaping strip 1, shaping strip 2, and shaping strip 3 are fixed into a whole by bolt 14, and bolt 215 is passed through threaded hole 413 on cover plate 7, waist groove 11 on shaping strip 1, shaping strip 2, and shaping strip 3 in sequence and fixed with shaping strip 4.

[0035] For further details, please refer to Figure 2 By loosening bolt 15 and pulling adjusting screw 5 outward, shaping strip 1, shaping strip 2, and shaping strip 3 can be moved outward as a whole, thereby expanding the dry shaping cavity.

[0036] For further details, please refer to Figure 2 It also includes profile 16, which is housed inside the dry-forming cavity.

[0037] In this embodiment, during the production of the profile 16, the operator loosens bolt 2 15 and pulls the adjusting screw 5 outward to move the shaping strip 1, shaping strip 2, and shaping strip 3 as a whole outward, thereby expanding the shaping cavity and ensuring that the profile 16 can enter the cavity quickly and accurately. After the profile 16 enters the cavity, the adjusting screw 5 is pushed inward to move the shaping strip 1, shaping strip 2, and shaping strip 3 as a whole inward until the expanded cavity is restored. Finally, bolt 2 15 is tightened.

[0038] The working principle and usage process of this invention are as follows: In the production of profile 16, the operator loosens bolt 2 15 and pulls the adjusting screw 5 outward, which moves the shaping strip 1, shaping strip 2, and shaping strip 3 as a whole outward, thereby expanding the dry shaping cavity and ensuring that the profile 16 can quickly and accurately enter the cavity. After the profile 16 enters the cavity, the adjusting screw 5 is pushed inward, causing the shaping strip 1, shaping strip 2, and shaping strip 3 as a whole to move inward until the expanded cavity is restored. Finally, bolt 2 15 is tightened. The above adjustment solves the problem that the profile 16 is difficult to enter the dry shaping and cooling system cavity during the production process. It is convenient to operate and should not be too complicated, but easy to process.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
