DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] like Figure 1 and Figure 2 As shown, the utility model provides an irregular opening aluminum profile 10, comprising a profile body 1, the profile body 1 having a cavity 11 therein, and one side of the profile body 1 having an opening 12 connected to the cavity 11;

[0032] The opening 12 is surrounded by two inclined plates 131 on the left and right sides of the profile body 1; the width of the outer end of the opening 12 gradually increases; an easily tearable support structure 2 is provided in the opening 12;

[0033] The left and right ends of the support structure 2 both have easy-tear portions 21 that are tilted toward the inside of the opening 12, and the outer ends of the easy-tear portions 21 are connected to the inclined plate 131 with a gradually decreasing width;

[0034] A notch 1311 is formed at the connection between the inclined plate 131 and the easy-tear portion 21 , and the outer end of the easy-tear portion 21 is connected to the notch 1311 .

[0035] Therefore, the open aluminum profile 10 having the support structure 2 with the easy-tear portion 21 can be easily produced and manufactured, and the support structure 2 can support the opening 12 to prevent the opening 12 from deforming, and the easy-tear portion 21 of the support structure 2 is connected to the notch 1311 set in the inclined plate 131 of the opening 12, which makes it easier to separate the easy-tear portion 21 and the inclined plate 131 of the opening 12, making the support structure 2 easier to tear and the tearing operation more labor-saving.

[0036] In this embodiment, the easy-tear portion 21 may be perpendicular to the inclined plate 131 , so that the easy-tear portion 21 and the inclined plate 131 can be separated more conveniently.

[0037] In this embodiment, the inner side of the easy-tear portion 21 close to the opening 12 is an inner bevel 211, and the outer side away from the opening 12 is an outer bevel 212. The angle between the inner bevel 211 and the inclined plate 131 is an acute angle. In the figure, the angle between the inner bevel 211 and the inner side wall 1312 of the inclined plate is 75°, and the main body of the easy-tear portion 21 and the inclined plate 131 are vertically arranged. By increasing the angle between the inner side of the easy-tear portion 21 and the inclined inner side wall 1312 of the inclined plate, the production of the mold can be facilitated, the probability of mold damage can be reduced, and the precision of product molding can be improved. The angle between the outer bevel 212 and the inclined plate 131 can also be an acute angle, in order to facilitate the separation of the easy-tear portion 21 and the inclined plate 131.

[0038] Another example Figure 1 As shown, the profile body 1 of this embodiment includes two side panels 13 and a transverse panel 14, both ends of which are connected to one side of two side panels 13 spaced apart on the left and right, and the other side of the side panel 13 has the inclined panel 131, thereby enclosing a cavity 11 with an opening 12.

[0039] like Figure 2 In this embodiment, the notch 1311 is a trapezoidal shape with a narrow inside and a wide outside, and the outer end of the easy-tear portion 21 is connected to the middle of the notch 1311. That is, the structure corresponding to the notch 1311 of the mold is not easy to break and damage, so as to facilitate the production of the mold.

[0040] For example Figures 3 to 8 The utility model also provides a mold 20 structure of an open aluminum profile 10 with a supporting structure 2, including an upper mold 3 and a lower mold 4, the upper mold 3 and the lower mold 4 are buckled together, the male head 31 of the upper mold 3 is sleeved in the female hole 41 of the lower mold 4, the male head 31 and the female hole 41 cooperate with each other to form the open aluminum profile 10 with the supporting structure 2.

[0041] Specifically, Figure 4 A lower guide groove 42 is provided on the top surface of the lower mold 4, and the female hole 41 is recessed in the lower guide groove 42, and the female hole 41 passes through the lower mold 4 from top to bottom.

[0042] like Figure 3 and Figure 5 The upper mold 3 is provided with three guide holes 32 , which pass through the upper mold 3 from top to bottom, and retaining ribs 33 are formed between adjacent guide holes 32 ; the male head 31 is protrudingly provided on the bottom surface of the lower mold 4 at the intersection of the three retaining ribs 33 .

[0043] See also Figure 8 When the bottom surface of the upper mold 3 covers the top surface of the lower mold 4, each guide hole 32 is connected to the lower guide groove 42, and the male head 31 is inserted into the female hole 41, and a forming groove 5 for forming the open aluminum profile 10 is formed between the male head 31 and the female hole 41.

[0044] Therefore, the guide hole 32 is used for feeding, and the material flows out from the forming groove 5 through the lower guide groove 42 to form the open aluminum profile 10 with the supporting structure 2.

[0045] In this embodiment, the molding groove 5 has two side plate grooves 51 corresponding to the side plate 13 and a support groove 52 corresponding to the support structure 2, and the three guide holes 32 are respectively aligned with the two side plate grooves 51 and the support groove 52 to increase the molding speed and improve the production efficiency.

[0046] In this embodiment, both ends of the support groove 52 are respectively provided with an easy-to-tear portion forming structure 53, which includes a first protrusion 531 provided on the female hole 41 and a second protrusion 532 provided on the male head 31. The first protrusion 531 is close to the second protrusion 532 on the side thereof and is a first inclined surface 5311, and the first inclined surface 5311 is used to form the outer inclined surface 212, and the second protrusion 532 is close to the second protrusion 532 on the side thereof and is a second inclined surface 5321, and the second inclined surface 5321 is used to form the inner inclined surface 211.

[0047] Since the tearable portion 21 is a raised structure, it can be produced by the cooperation between the first protrusion 531 and the second protrusion 532 , so that the mold 20 is more convenient to support and the profile is more convenient to produce.

[0048] The first protrusion 531 has a third inclined surface 5312 and a first plane 5313 on the side close to the side plate groove 51, and the second protrusion 532 has a fourth inclined surface 5322 and a second plane 5323 on the side close to the side plate groove 51. The third inclined surface 5312, the first plane 5313, the fourth inclined surface 5322 and the second plane 5323 are used to form the missing groove 1311 on the inclined plate 131.

[0049] In this way, the service life of the first protrusion 531 and the second protrusion 532 can be improved, and the outer end parts of the two protrusions close to the side plate groove 51 can be more wear-resistant and less likely to break and be damaged, thereby ensuring production accuracy, thereby improving the service life of the mold 20, reducing the cost of the mold 20, and improving production efficiency.

[0050] In summary, the utility model provides an open aluminum profile 10 with a support structure 2, wherein the support structure 2 has an easy-tear portion 21, which can effectively support the opening 12 with the inclined plate 131 to prevent the opening 12 from deforming, and the support structure 2 is easy to tear. At the same time, the tilting setting of the easy-tear portion 21 and the setting of the notch 1311 on the inclined plate 131 make the production of the mold 20 more convenient, and can ensure the service life of the mold 20 and improve production efficiency.
