[0029] The following is for reference. Figures 1 to 5 Describes an extrusion die with an inlay structure according to an embodiment of the present invention.
[0030] like Figures 1 to 4As shown, the extrusion die with an inlay structure according to an embodiment of the present invention includes: a die body 100, an insert 200, and a fixing mechanism. One end of the die body 100 is provided with a hollow hole 101, and the other end is provided with a welding cavity 102. The bottom of the welding cavity 102 is provided with an insert groove 103 communicating with the hollow hole 101. The insert 200 can be inserted into the insert groove 103 and is provided with a die hole 201 communicating with the hollow hole 101 and the welding cavity 102. The fixing mechanism is provided between the die body 100 and the insert 200 for fixing the insert 200 into the insert groove 103.
[0031] The welding cavity 102 and the empty knife hole 101 are connected through the die hole 201 of the insert 200 to form a die that can meet the requirements of aluminum profile extrusion processing. It can effectively utilize waste die, and the die body 100 can be reused, reducing the cost of the die. It also eliminates the need for frequent die opening and replacement, thus improving work efficiency.
[0032] Specifically, a groove 103 is machined in the mold body 100 (such as a scrap mold), and an insert 200 and its die hole 201 are machined according to the groove 103. The insert 200 is fixed into the groove 103 by a fixing mechanism, thus forming an extrusion mold that meets the requirements of aluminum profile extrusion processing. When the insert 200 and its die hole 201 are damaged or have large errors, the insert 200 can be directly replaced without replacing the entire mold.
[0033] In some embodiments of this utility model, the insert 200 can be detachably installed onto the mold body 100 through a fixing mechanism, so as to facilitate the replacement of old and new inserts 200 or the installation of inserts 200 of different models, and meet different production and processing requirements.
[0034] like Figure 3 As shown, in some embodiments of this utility model, the front end face 202 of the insert 200 facing the welding cavity 102 is flush with the bottom end face 104 of the welding cavity 102, so as to reduce the impact of the insert 200 on the welding cavity 102.
[0035] Specifically, the bottom end face 104 of the welding cavity 102 is a planar structure, the insert groove 103 is located in the middle of the bottom end face 104, and the front end face 202 of the insert is a planar structure. After the insert 200 is inserted into the insert groove 103, the front end face 202 of the insert and the bottom end face 104 together form the bottom surface of the welding cavity 102. By adopting this planar alignment structure, not only can the processing difficulty of the insert 200 and the insert groove 103 be reduced, but the original structure of the welding cavity 102 can be better maintained, the normal function of the welding cavity 102 can be maintained, and the influence of the setting of the insert 200 on the welding cavity 102 can be reduced. Moreover, during production and processing, the insert 200 is basically only subjected to axial (from front to back) pushing force, and the insert 200 is not prone to lateral displacement or deformation, which can better ensure the accuracy of extrusion processing.
[0036] like Figure 3 As shown, in some embodiments of this utility model, a welding transition structure 106 is provided at the junction of the side wall 105 of the welding cavity 102 and the bottom end face 104 of the welding cavity 102. The edge of the insert 200 is spaced a distance a from the welding transition structure 106, that is, the insert 200 only forms a part of the bottom surface of the welding cavity 102, thereby reducing the impact on the welding transition structure 106.
[0037] Yes, due to the inherent errors in machining, if the insert 200 forms part of the welded transition structure 106, the error can easily affect the flow of aluminum material, causing turbulence and affecting the original design effect of the mold. At the same time, the welded transition structure 106 is generally a rounded corner or beveled structure. If the insert 200 forms part of the welded transition structure 106, it can easily cause the insert 200 to be subjected to lateral pressure, causing the insert 200 to shift laterally or deform, affecting the normal extrusion of aluminum material.
[0038] like Figure 3 As shown, in some embodiments of this utility model, the interval distance a is set to be greater than or equal to 2mm in order to reduce the influence of the insert 200 on the original structure of the welding cavity 102.
[0039] In some embodiments of this utility model, the fixing mechanism is a pushing mechanism. The pushing mechanism can apply a pushing force to the insert 200 toward the groove 103, that is, push the insert 200 into the groove 103 and maintain the pushing force so that the insert 200 is fixed in the groove 103.
[0040] It is understood that in some embodiments of this utility model, the fixing mechanism may also be a pin mechanism, a screw mechanism, etc., which can also meet the installation requirements of the insert 200.
[0041] like Figure 2 , Figure 3 , Figure 5 As shown, in some embodiments of this utility model, the insert 200 is provided with a pressing groove. The groove wall of the pressing groove facing the bottom of the insert groove 103 is a pressure-receiving inclined surface 301 that is inclined towards the bottom of the insert groove 103. The mold body 100 is provided with a guide groove 302 corresponding to the pressing groove. The pressing mechanism includes a pressing block 310 that is slidably disposed in the guide groove 302 and a driving component that can drive the pressing block 310 to move toward the pressing groove. The end of the pressing block 310 is provided with a pressing inclined surface 303 corresponding to the pressure-receiving inclined surface 301. When the driving component drives the pressing block 310 to move toward the pressing groove, the pressing inclined surface 303 squeezes the pressure-receiving inclined surface 301, thereby generating a pushing force on the insert 200 toward the insert groove 103, so that the insert 200 is fixed in the insert groove 103.
[0042] like Figure 2 , Figure 3As shown, in some embodiments of this utility model, the driving component includes a fixing block 320 and a pressing screw 330. The fixing block 320 is installed on the mold body 100. The fixing block 320 is provided with a threaded hole 321 corresponding to the pressing screw 330. The pressing screw 330 can be screwed into the threaded hole 321 and pressed against the pressing block 310, thereby pressing the pressing block 310.
[0043] It is understood that in some embodiments of this utility model, the pushing mechanism may also be a screw pressing mechanism, such as directly pressing the insert 200 with a screw.
[0044] like Figure 2 As shown, in some embodiments of this utility model, the mold body 100 is provided with a slide groove 322, and the fixing block 320 can be slidably disposed in the slide groove 322. The fixing block 320 is installed through the sliding structure, which is convenient for installation.
[0045] Specifically, at least one end of the slide 322 is connected to the outer contour surface of the mold body 100 to facilitate the removal and insertion of the fixing block 320.
[0046] like Figure 2 As shown, in some embodiments of this utility model, the groove 322 penetrates through the mold body 100 to facilitate the installation of the fixing block 320.
[0047] It is understood that in some embodiments of this utility model, one end of the slide groove 322 is a limiting structure. When the fixing block 320 slides to abut against the limiting structure, the threaded hole 321 is aligned with the guide groove 302. At this time, the top pressing screw 330 can be screwed in to press the pushing block 310.
[0048] In some embodiments of this utility model, the fixing block 320 can slide to open the guide groove 302 to facilitate the installation and disassembly of the pushing block 310.
[0049] It is understood that in some embodiments of this utility model, the fixing block 320 can also be installed to the mold body 100 by screws or the like.
[0050] like Figure 2 , Figure 3 As shown, in some embodiments of this utility model, the bottom of the cross-section of the fixing block 320 is trapezoidal, and the sliding groove 322 is a dovetail groove corresponding to the fixing block 320, thereby realizing the sliding installation of the fixing block 320.
[0051] It is understood that in some embodiments of this utility model, the bottom of the cross-section of the fixing block 320 can also be set as an inverted T-shaped structure, and the sliding groove 322 is a corresponding inverted T-shaped sliding groove, which can also meet the requirements of sliding installation.
[0052] In some embodiments of this utility model, a sliding positioning mechanism is provided between the fixing block 320 and the slide groove 322 to position the fixing block 320 in the slide groove 322.
[0053] Specifically, the sliding positioning mechanism is a screw mechanism. A threaded hole is provided in the mold body 100, which extends through the slide groove 322. A positioning screw is installed in the threaded hole. When the fixing block 320 is installed in the set position, the positioning screw is screwed in. The positioning screw presses against the fixing block 320, thereby fixing the position of the fixing block 320.
[0054] It is understood that in some embodiments of this utility model, the sliding positioning structure can also be a pin mechanism, with the fixing block 320 and the mold body 100 respectively provided with corresponding pin holes, and the pins inserted between the fixing block 320 and the mold body 100, thereby positioning the relative positions of the fixing block 320 and the mold body 100.
[0055] like Figures 1 to 4 As shown, in some embodiments of this utility model, the outer side of the fixing block 320 is a contour-following structure 323 corresponding to the outer contour of the mold body 100, so as to reduce the impact on the outer contour of the mold body 100 and avoid interference with the original mold installation or fixing mechanism.
[0056] Specifically, the mold body 100 has a cylindrical structure, and the contour structure 323 has a corresponding arc surface structure, so that the mold body 100 can smoothly transition at the installation position of the fixing block 320.
[0057] like Figure 3 , Figure 4 As shown, in some embodiments of this utility model, when the pressing mechanism fixes the insert 200 to the mold body 100, the top pressing screw 330 does not protrude from the outer surface of the fixing block 320, so as to avoid interference with the mold installation or fixing mechanism.
[0058] like Figure 2 , Figure 4 As shown, in some embodiments of this utility model, the end of the push block 310 is provided with an external threaded hole 311, which can cooperate with an external screw to facilitate the removal of the push block 310.
[0059] Specifically, after the mold is assembled, the push block 310 will also be squeezed by the reaction force. After a long period of use, the push block 310 is very likely to stick or jam to the mold body 100, making it difficult for the push block 310 to move from the guide groove 302, causing the insert 200 to be unable to be removed. By setting the external threaded hole 311, after the fixing block 320 is removed, the opening of the guide groove 302 is exposed. The external threaded hole 311 can cooperate with the external screw to facilitate the removal of the push block 310.
[0060] like Figure 4 As shown, in some embodiments of this utility model, the external threaded hole 311 and the pressing screw 330 are misaligned, so that the pressing screw 330 will not press against the external threaded hole 311, thereby maintaining the normal screwing performance of the external threaded hole 311.
[0061] Specifically, there are two external threaded holes 311, which are respectively located on both sides of the pressing position of the pressing screw 330 on the upper end face of the pressing block 310.
[0062] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
