[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in the description of the present invention, "multiple" and "several" mean at least two, for example two, three, etc., unless otherwise clearly and specifically defined.

[0036] See also Figure 1 and Figure 2 As shown, the utility model is a blister aluminum alloy welding mold structure, including a plurality of blister main body templates 2, the plurality of blister main body templates 2 are combined and assembled into a mold for blister forming a refrigerator liner, and the mold is positioned and arranged on a base 1; wherein, when adjacent blister main body templates 2 are assembled, the seams between adjacent blister main body templates 2 are connected by stir friction welding.

[0037] During the manufacturing process of the aluminum alloy blister welding mold structure of the present application, it is convenient to assemble a plurality of blister main body templates 2 into a mold for blister molding refrigerator liner, and adopt stir friction welding to weld and fix adjacent blister main body templates 2. Under the same molding conditions, the difference in the extreme molding rhythm between the welding mold and the sand casting mold is compared, and the efficiency is improved by about 20%; and the efficient molding welding mold effectively solves the casting defects of the sand casting mold and meets the high-quality appearance requirements of mid-to-high-end products.

[0038] It should be understood that in the process of mold welding, stir friction welding is used. Stir friction welding is also called FSW. As a solid-phase connection method, it overcomes the shortcomings of previous fusion welding, such as pores, cracks, and deformation. Its principle is to use a high-speed rotating stirring head to stir and rub the welding material, forming a stable friction heat to partially melt the material, and then use the high-speed rotation of the stirring head to stir and mix the liquid material evenly, and finally form a complete weld; stir friction welding makes the welding of the blister body template 2 unnecessary for secondary processing, and after simple polishing, there is no obvious appearance defect around the weld of the welding mold.

[0039] like Figure 1 and Figure 2 As shown, a raised positioning platform 4 of an integral structure is provided on the assembly end surface of the blister main body template 2, and adjacent blister main body templates 2 are fixedly assembled and connected by the raised positioning platform 4; in the process of combining and assembling multiple blister main body templates 2, it is convenient to fix them by welding through the raised positioning platform 4, so as to increase the bite strength between the blister main body templates 2 and ensure the welding quality.

[0040] like Figure 1 and Figure 2As shown, multiple blister main body templates 2 include a blister left end template 20, a blister mirror image side end upper template 21, a blister mirror image side end lower template 22, a blister right end upper template 23, a blister right end lower template 24 and a blister top template 25. The blister mirror image side end upper template 21 and the blister mirror image side end lower template 22 are assembled into a blister mirror image side end whole template, the blister right end upper template 23 and the blister right end lower template 24 are assembled into a blister right end whole template, the blister mirror image side end whole template, the blister right end whole template, the blister left end template 20 and the blister top template 25 are assembled into a mold for blister molding a refrigerator liner; in the process of combining and assembling multiple blister main body templates 2, the mold for combining and assembling the refrigerator liner is easy to operate, ensuring the molding quality of the welding mold.

[0041] In this specific embodiment, when the blister mirror image side end whole template, the blister right end whole template, the blister left end template 20 and the blister top template 25 are assembled, the adjacent assembled end face seams are connected by stir friction welding to ensure that the welding molding quality at the adjacent assembled end face seams is good.

[0042] In this specific embodiment, when the upper template 21 of the blister mirror image side end and the lower template 22 of the blister mirror image side end are assembled as a whole, the adjacent assembled end face seams are connected by stir friction welding, so that the welding molding quality of the entire blister mirror image side end template at the adjacent assembled end face seams is good.

[0043] In this specific embodiment, when the upper template 23 and the lower template 24 are assembled together, the adjacent end seams are connected by friction stir welding, so that the welding quality of the entire template at the right end of the blister is good.

[0044] In this specific implementation mode, Figure 3 As shown, each blister body template 2 is drilled with a water channel network 3, and the inner diameter of the water channel network 3 can be Φ12mm, so that each blister body template 2 can be cooled, thereby improving the cooling efficiency of the mold for assembling and forming the refrigerator liner.

[0045] In this specific embodiment, each blister body template 2 is made of aluminum alloy. The aluminum alloy template is light in weight and has good thermal conductivity, which is convenient for processing and forming welding molds, so that the molding quality of the refrigerator liner mold is guaranteed.

[0046] In this specific implementation mode, Figure 1 and Figure 2As shown, each blister main body template 2 is respectively drilled with a vacuum suction hole 5, and the vacuum suction hole 5 is used to fix and fit the blister-cooled refrigerator liner product on the mold surface for molding. In the process of drilling the vacuum suction hole 5, a drilling and punching process is adopted. First, a Ø6mm round hole is punched from the inside of the mold cavity, and then a vacuum suction hole 5 is drilled at about 5mm from the outer wall of the mold core, so that the effective length of the vacuum suction hole 5 is about 1 / 4 of the sand casting mold, which greatly improves the vacuum suction efficiency of the blister.

[0047] In this specific implementation mode, Figure 4 As shown, a positioning groove 10 for positioning and assembling the mold is provided on the base 1, and the positioning groove 10 can prevent the mold from being offset when being assembled.

[0048] In the manufacturing process of the aluminum alloy welding mold structure of the present application, the process route adopted is: rough processing of the aluminum alloy blister main body template - water channel drilling arrangement - assembly and positioning of the aluminum alloy blister main body template - assembly and welding of the aluminum alloy blister main body template - aging treatment - fine processing of the aluminum alloy blister main body template; the specific implementation steps are as follows:

[0049] Step 1: Confirm the parting position according to the lining structure, select the aluminum alloy hard aluminum plate and roughly process it into an independent template of the aluminum alloy blister body according to the product appearance, such as Figures 5 to 7 As shown, the independent parting position lining structure of the blister aluminum alloy welding mold of the present application.

[0050] Step 2: After rough processing into independent templates of aluminum alloy blister body, each independent template is drilled with a waterway network, such as Figure 8 A schematic diagram of the water channel network arrangement on one side is shown. The inner diameter of the water channel network can be Φ12mm, so that each independent template can be cooled, thereby improving the cooling efficiency of the mold for assembling and forming the refrigerator liner.

[0051] Step 3: When each independent template is assembled into a refrigerator liner mold for blister forming, Fig. 9 The schematic diagram of the assembly and connection between adjacent blister body templates through the raised positioning platform is shown, which facilitates the fixation of the templates before welding through the raised positioning platform to increase the bite strength between the blister body templates and ensure the welding quality.

[0052] Step 4: The assembled aluminum alloy blister body templates are welded at the adjacent assembly gap positions. Fig.10 The schematic diagram of the assembly weld positions between adjacent blister body templates is shown. The FSW welding process is adopted to make the adjacent blister body templates firm and age-treated.

[0053] Step 5: After aging treatment, the aluminum alloy blister body template is finely processed to ensure the molding quality of the blister product.

[0054] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
