Description

Technical Field

[0001] This utility model relates to the field of extrusion dies, and in particular to a metal profile extrusion die with adjustable height. Background Technology

[0002] Composite aluminum-plastic flooring is a product made by using metal profiles as the base material, then bonding a polymer composite material onto the surface through an extrusion die and shaping it. A crucial part of this process is the extrusion die. The die has a through-cavity to allow the metal profile to pass through at a uniform speed, and an extrusion nozzle at the top of the cavity continuously and evenly extrudes the molten polymer composite material onto the upper surface of the metal profile. Currently, extrusion dies are designed for a single specification, which leads to a problem: many metal profiles have the same width but differ in thickness. This single-specification method requires manufacturers to create too many dies, thus increasing production costs, making it difficult to lower product prices, increasing the burden on consumers, and adding to the production and die warehousing burden for companies. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide an extrusion die capable of handling metal profiles of varying thicknesses.

[0004] The technical solution adopted by this utility model to solve the problem is: a metal profile extrusion die with easily adjustable height, comprising:

[0005] The mold body has a through mounting groove at the bottom, and several blind holes arranged along the height direction are symmetrically arranged on the two side walls of the mounting groove. The bottom of the mold body has a threaded adjustment hole that extends to the bottom surface of the blind holes. The top of the mounting groove has an extrusion port, and the mold body has an extrusion channel that communicates with the extrusion port.

[0006] An adjusting block is provided in the blind hole and can move up and down in the blind hole. A mounting hole is provided in the middle of the adjusting block, and a bearing is sleeved in the mounting hole.

[0007] A support roller is arranged on the mounting groove, and both ends of the support roller are respectively inserted into the bearings on the opposing adjustment blocks on both sides of the mounting groove. The support roller and the top of the mounting groove form a mold cavity for accommodating the metal profile.

[0008] An adjusting bolt is screwed into the threaded adjusting hole, and the end of the adjusting bolt is rotatably mounted on the lower end of the adjusting block.

[0009] As a further improvement to the above technical solution, the support roller includes a main shaft in the middle and auxiliary shafts located at both ends of the main shaft. The diameter of the auxiliary shaft is smaller than the diameter of the main shaft, and the diameter of the main shaft is larger than the diameter of the bearing.

[0010] As a further improvement to the above technical solution, a transversely arranged through groove is provided at the lower part of the adjusting block, and an entry groove connecting to the bottom surface of the adjusting block is provided at the center of the bottom of the through groove, wherein the two side walls of the entry groove are both located inside the through groove.

[0011] The end of the adjusting bolt is provided with a connecting column section and an anti-detachment column located at the end of the connecting column section. The diameter of the anti-detachment column is larger than the entry groove and smaller than the through groove. The diameter of the connecting column section is smaller than the entry groove. The anti-detachment column and the connecting column section can enter the through groove and the entry groove simultaneously through the side of the adjusting block and rotate freely therein.

[0012] As a further improvement to the above technical solution, the spacing between blind holes on the same side of the mounting groove is 5-15cm.

[0013] The beneficial effects of this invention are as follows: During use, the adjusting bolt first lowers the adjusting block, expanding the module space. The metal profile is then passed through the mold cavity. Next, the adjusting bolt is rotated within the threaded adjusting hole, causing the adjusting block to move upwards. This, in turn, moves the metal profile upwards via the support roller, thus precisely controlling the position of the metal profile within the mold cavity. This, in turn, controls the thickness of the molten polymer composite material extruded from the extruder onto the surface of the metal profile. Therefore, this solution, by using an adjusting bolt to move the adjusting block and subsequently the support roller within the mounting groove, can accommodate metal profiles of varying thicknesses and the extrusion of polymer composite materials of different thicknesses onto the surface of the metal profile. This enhances compatibility and significantly reduces mold-making costs for enterprises. Attached Figure Description

[0021] Reference Figures 1 to 2 A metal profile extrusion die with adjustable height, comprising:

[0022] The mold body 10 has a through mounting groove 11 at its bottom, and several blind holes 12 arranged along the height direction are symmetrically arranged on both side walls of the mounting groove 11. The bottom of the mold body 10 has a threaded adjustment hole 121 that extends to the bottom surface of the blind hole 12. The top of the mounting groove 11 has an extrusion port, and the mold body 10 has an extrusion channel 13 that communicates with the extrusion port.

[0023] An adjusting block 20 is disposed in the blind hole 12 and can move up and down in the blind hole 12. An installation hole is provided in the middle of the adjusting block 20, and a bearing 21 is sleeved in the installation hole.

[0024] A support roller 30 is arranged on the mounting groove 11, and both ends of the support roller 30 are respectively inserted into the bearings 21 on the adjusting blocks 20 on the opposite side walls of the mounting groove 11. A mold cavity for accommodating the metal profile is formed between the support roller 30 and the top of the mounting groove 11.

[0025] An adjusting bolt 40 is screwed into the threaded adjusting hole 121, and the end of the adjusting bolt 40 is rotatably mounted on the lower end of the adjusting block 20.

[0026] In operation, the adjusting bolt 40 first lowers the adjusting block 20, expanding the module space. The metal profile is then passed through the mold cavity. The adjusting bolt 40 is then rotated within the threaded adjusting hole 121, causing the adjusting block 20 to move upwards. This movement, via the support roller 30, moves the metal profile upwards, precisely controlling its position within the mold cavity and consequently the thickness of the molten polymer composite material extruded from the extruder onto the metal profile surface. This solution, by using the adjusting bolt 40 to move the adjusting block 20, which in turn moves the support roller 30 within the mounting groove 11, can accommodate metal profiles of varying thicknesses and the extrusion of polymer composite materials of different thicknesses onto the metal profile surface. This enhanced compatibility significantly reduces mold-making costs for businesses.

[0027] To further optimize the system, in order to enable the support roller 30 to both fix the bearing 21 while being mounted on it, the support roller 30 preferably includes a main shaft 31 in the middle and auxiliary shafts 32 at both ends of the main shaft 31. The diameter of the auxiliary shaft 32 is smaller than the diameter of the main shaft 31, and the diameter of the main shaft 31 is larger than the diameter of the bearing 21. The main shaft 31 restricts the bearing 21 from dislodging.

[0028] There are many ways to rotatably mount the end of the adjusting bolt 40 to the lower end of the adjusting block 20. The simplest way is to make the end of the adjusting bolt 40 directly abut against the lower end face of the adjusting block 20, thereby driving the adjusting block 20 to rise and fall.

[0029] Considering the stability of the movement, it is preferable that the lower part of the adjusting block 20 is provided with a horizontally arranged through groove 22, and the center of the bottom of the through groove 22 is provided with an entry groove 23 connecting to the bottom surface of the adjusting block 20, wherein both side walls of the entry groove 23 are located inside the through groove 22; the end of the adjusting bolt 40 is provided with a connecting column section 41 and an anti-detachment column 42 located at the end of the connecting column section 41. The diameter of the anti-detachment column 42 is larger than the entry groove 23 and smaller than the through groove 22, and the diameter of the connecting column section 41 is smaller than the entry groove 23. The anti-detachment column 42 and the connecting column section 41 can enter the through groove 22 and the entry groove 23 simultaneously through the side of the adjusting block 20 and rotate freely therein. In this way, the anti-detachment column 42 is locked in the through groove 22, so that the adjusting block 20 can completely follow the displacement of the adjusting bolt 40, thereby making the adjustment more accurate.

[0030] Further optimization is made, with the spacing between blind holes 12 on the same side of the mounting groove 11 being preferably 5-15cm. This makes the distance between all the side-by-side support rollers 30 more balanced, and can better support the metal profile.

[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
