Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an anti-hidden crack cast aluminum mold. Background Art

[0002] Aluminum casting is a process in which molten aluminum is poured into a mold and cooled to form aluminum parts of the desired shape. However, in the process of aluminum casting in existing molds, the molten aluminum liquid contacts the air inside the mold, causing the air to expand, which will cause the aluminum liquid poured into the mold to boil out and splash. In addition, in the process of pouring molten aluminum into the mold, the molten aluminum contacts the bottom of the mold and splashes. The poured aluminum liquid cannot enter the mold cavity smoothly and evenly, which will cause local overheating or uneven cooling, resulting in dark cracks in the casting. Utility Model Content

[0016] 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 in 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.

[0017] See also Figure 1-4 The utility model provides a technical solution: an anti-hidden crack cast aluminum mold, comprising a first mold 1, a second mold 2, a feed funnel 7 and a guide rod 13, the first mold 1 and the second mold 2 are symmetrically arranged, a casting port 5 is penetrated through the top of the adjacent side of the first mold 1 and the second mold 2, a slot 6 is opened at the inner top of the casting port 5, the feed funnel 7 is arranged above the connection between the first mold 1 and the second mold 2, the bottom of the feed funnel 7 is fixedly connected with a feed pipe 8, the feed pipe 8 is movably plugged into the inside of the slot 6 and connected with the casting port 5;

[0018] The inner top of the feed funnel 7 is fixedly connected to a baffle 11 through a connecting rod 10, and a ring plate 12 is arranged below the baffle 11. The ring plate 12 is fixedly connected to the inner wall of the feed funnel 7, and an adaptation hole 14 is opened through the top of the baffle 11. The adaptation hole 14 is adapted to be arranged along the guide rod 13, and the adaptation hole 14 and the ring plate 12 are sequentially penetrated along the guide rod 13 to extend to the inner bottom of the connection between the first mold 1 and the second mold 2.

[0019] A connecting wing plate 3 is fixedly connected to the outer wall of the adjacent end of the first mold 1 and the second mold 2, and the two connecting wing plates 3 are connected by a locking bolt 4. The two connecting wing plates 3 can be connected by the locking bolt 4, so that the first mold 1 and the second mold 2 are locked and connected.

[0020] A support frame 9 is fixedly connected to the outer wall of the feed funnel 7. The support frame 9 is arranged on both sides of the connecting wing plates 3 on both sides of the feed funnel 7, and the support frame 9 is movably connected to the connecting wing plates 3. The support frame 9 can support the feed funnel 7, which can effectively prevent the feed funnel 7 from being unstable and spilling the molten aluminum during the process of pouring the molten aluminum into the mold along the feed funnel 7.

[0021] The inner diameter of the ring plate 12 is smaller than the diameter of the baffle 11 , which can effectively prevent the aluminum liquid from splashing out when it contacts with air during the process of being cast into the mold.
