[0001] The utility model relates to the technical field of casting, in particular to a tool for making self-made high-quality aluminum alloy welding rods. Background Art

[0002] Aluminum alloy casting welding is an important technical means of repairing castings. At present, the welding rods used for casting welding are mostly finished welding rods or hand-cast welding rods. Since the finished welding rods are different from the material of the castings, after being used as welding materials for welding, the color difference of the castings will be inconsistent after surface treatment, which will bring surface quality problems; the hand-cast same-furnace welding rods are mostly directly drawn and cast on the template. Due to limited casting conditions, the cast welding rods often contain defects such as inclusions and pores. At the same time, the cast welding rods are of different sizes and shapes. Inclusions, pores and other defects inside the welding material are often an important source of defects in flaw detection after casting welding. At the same time, the different sizes of welding rods also bring great difficulty to the stable arc striking operation of welding, resulting in unstable quality of the entire casting welding and difficult operation. For this reason, we propose a tool for homemade high-quality aluminum alloy welding rods. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6This embodiment provides a technical solution: a tool for making self-made high-quality aluminum alloy welding rods, comprising a lower base plate 1, on which are provided a sliding fixed left half mold 2 and a right half mold 3, the left half mold 2 and the right half mold 3 being symmetrical structures, and provided on the left half mold 2 and the right half mold 3 with a sliding connected upper left half mold 4 and an upper right half mold 5, the upper left half mold 4 and the upper right half mold 5 being symmetrical structures, and a cavity casting system 12 for forming a welding rod sample 7 is provided inside the combined structure of the lower base plate 1, the left half mold 2, the right half mold 3, the upper left half mold 4 and the upper right half mold 5;

[0026] The pouring system 12 includes a pouring cup 41 , a ceramic filter mesh 21 , a sprue 22 , a runner 11 , an ingate 12 , a slag collecting area 15 and an exhaust hole 16 .

[0027] Among them: the pouring cup 41 in the pouring system 12 is a conical structure, symmetrically formed between the upper left half mold 4 and the upper right half mold 5, and a ceramic filter mesh 21 is connected to the bottom of the pouring cup 41. The ceramic filter mesh 21 is a circular structure, and a ceramic filter 9 can be inserted to fully filter the poured aluminum liquid and remove oxide scale and impurities. The bottom of the ceramic filter mesh 21 is connected to a sprue 22. The ceramic filter mesh 21 and the sprue 22 are symmetrically formed between the left half mold 2 and the right half mold 3. The bottom of the sprue 22 is connected to a rectangular cross runner 11, and the end of the cross runner 11 is connected to an inner gate 12. The inner gate 12 is a U-shaped structure, which is centrally connected to the welding rod forming area 13. The openings 12 are evenly distributed, which can make the flow to the welding rod forming area 13 balanced and stable, avoiding local overheating problems caused by inconsistent flow rates. A slag collecting area 15 is provided at the end of the welding rod forming area 13. The slag collecting area 15 can store the aluminum liquid flowing in the initial stage. The aluminum liquid in the initial stage contains more oxide inclusions and gases, so the purity of the aluminum liquid flowing into the welding rod forming area 13 in the later stage can be guaranteed. A through exhaust hole 16 is provided on the upper part of the slag collecting area 15. The exhaust hole 16 can avoid the reaction force of the gas in the mold cavity, making the pouring and filling smoother. The runner 11, the inner gate 12, the slag collecting area 15 and the exhaust hole 16 are all symmetrically formed between the lower base plate 1, the left half mold 2 and the right half mold 3.

[0028] The cross-sectional area ratio of the sprue 22, runner 11, and ingate 12 is 1:1.2:1.5. The open pouring system ensures smooth filling and avoids secondary oxidation of the molten aluminum sprayed into the cavity. The sprue 22 has a serpentine structure, which can reduce the impact force of the molten aluminum, changing the laminar flow of the molten aluminum into turbulent flow, resulting in a smoother flow.

[0029] Wherein: the two ends of the welding rod forming area 13 are provided with truncation blocks 14, which can form fractures 9 at both ends of the cast welding rod sample 7, so as to facilitate fast and accurate cutting.

[0030] Among them: guide strips 17 with through protrusions are symmetrically arranged on both sides of the lower base plate 1, and a first positioning platform 18 is arranged in the middle of the guide strips 17; guide grooves 23 are symmetrically arranged on both sides of the lower part of the left half mold 2 and the right half mold 3, and a first positioning groove 26 is arranged at the centripetal end of the guide groove 23. The guide strips 17 and the guide grooves 23 slide in opposite directions. Through the positioning of the first positioning platform 18 and the first positioning groove 26, the lower base plate 1 and the left half mold 2 and the right half mold 3 can be inserted and pulled quickly and positioned accurately.

[0031] Among them: a through-protruding dovetail block 27 is provided on the upper part of the left half mold 2 and the right half mold 3, a second positioning platform 24 is provided in the center of the upper part of the left half mold 2 and the right half mold 3 away from the exhaust hole 16, and a through dovetail groove 42 and a second positioning groove 43 are provided on the bottom of the upper left half mold 4 and the upper right half mold 5. The dovetail block 27 and the dovetail groove 42 slide in opposite directions. Through the positioning of the second positioning platform 24 and the second positioning groove 43, the insertion and pulling of the left half mold 2, the right half mold 3 and the upper left half mold 4, and the upper right half mold 5 can be fast and accurate.

[0032] Among them: the lower base plate 1 is symmetrically provided with a through first bolt hole 19, and the left half mold 2 and the right half mold 3 are provided with a second bolt hole 25 on the vest side. The first bolt hole 19 and the second bolt hole 25 are through-connected, and bolts can be used to fix the lower base plate 1 and the left half mold 2 and the right half mold 3. The bottom of the first bolt hole 19 is an enlarged hexagonal structure, which can automatically lock the bolt head when the bolt is tightened to prevent rotation, facilitating quick operation.

[0033] Among them, the lower base plate 1 is symmetrically provided with weight-reducing holes 112, which can reduce the weight of the lower base plate and prevent deformation. The lower base plate 1 is symmetrically provided with through handle holes 111 at both ends for easy transportation.

[0034] Among them: the tooling material is H13 steel, which can be used frequently to extend the service life of the tooling.

[0035] The working principle of a tooling for self-made high-quality aluminum alloy welding rods provided by the utility model is as follows: first, lift the handle 6 to push the left half mold 2 and the right half mold 3 toward the center along the guide strip 17 on the lower base plate 1 respectively. When they are pushed to the first positioning platform 18, the insertion is completed. At this time, the lower base plate 1 and the left half mold 2 and the right half mold 3 are locked and fixed with bolts through the first bolt hole 19 and the second bolt hole 25. The ceramic filter mesh 8 is placed at the position of the ceramic filter mesh hole 21. The upper left half mold 4 and the upper right half mold 5 are respectively installed along the dovetail block 27 and pushed toward the center. When they are pushed to the second positioning platform 24, the insertion is completed. The assembly is completed; the molten aluminum alloy liquid is poured in from the pouring cup 41, filtered by the ceramic filter mesh 8, and flows evenly into the welding rod forming area 13 along the sprue 22, the cross runner 11, and the inner gate 12. The alloy liquid carrying oxide inclusions and pores at the front end is exhausted through the exhaust hole 16 and stored in the slag collection area 15. After cooling, the upper left half mold 4, the upper right half mold 5, the left half mold 2, and the right half mold 3 are opened to the left and right respectively, and the welding rod sample 7 can be taken out, and the fracture 9 at both ends of the welding rod sample 7 is broken, and the upper pouring system 12 and the slag collecting column 10 at the tail are removed to obtain a high-quality welding rod sample 7 with uniform specifications.
