Description

Technical Field

[0001] This utility model relates to the field of casting technology, and more specifically to a pouring basin structure. Background Technology

[0002] Sand casting is a casting method used to manufacture metal castings, and its design plays a crucial role in the quality and performance of the castings. In sand casting, the pouring bowl is an indispensable component, responsible for guiding molten metal into the mold cavity.

[0003] However, existing pouring basins have the following drawbacks:

[0004] 1) Low yield: The redundant design of the pouring basin (such as funnel-shaped or basin-shaped) leads to excessive consumption of molten metal, resulting in a low yield, which is especially noticeable for small castings.

[0005] 2) Frequent process defects: Severe air entrapment and poor exhaust lead to casting defects, indirectly affecting the yield.

[0006] Therefore, providing a pouring basin structure with high yield is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the present invention provides a pouring basin structure to improve the yield and enhance the quality and stability of castings.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A pouring basin structure includes a pouring cup and a collection ring. The lower part of the pouring cup has a plurality of radially distributed venting channels. The pouring cup is fitted into the interface of the collection ring to form a collection groove between the pouring cup and the collection ring. The outlet of each of the venting channels corresponds to the position of the collection groove.

[0010] By adopting the above technical solutions, this utility model produces the following beneficial effects:

[0011] By modularly combining the pouring cup and the liquid collecting ring, and by opening multiple venting channels on the pouring cup, the venting of molten metal during the casting process can be improved, the amount of molten metal used can be reduced, and the yield can be increased.

[0012] Furthermore, the pouring cup is funnel-shaped.

[0013] Furthermore, the pouring cup has a conical hole and a cylindrical hole that are connected from top to bottom; a plurality of the exhaust channels are evenly arranged along the circumference of the cylindrical hole.

[0014] Furthermore, there are 6 exhaust channels, and each exhaust channel has a diameter of 8mm.

[0015] Furthermore, the lower part of the pouring cup located below the venting channel is in close contact with the interface of the liquid collecting ring.

[0016] The beneficial effect of adopting the above-mentioned further technical solution is to ensure the sealing between the interface of the pouring cup and the collecting ring, and to prevent the molten metal in the collecting tank from leaking out from the interface between the pouring cup and the collecting ring.

[0017] Furthermore, each of the exhaust channels is located at the same horizontal level as the liquid collection tank.

[0018] The beneficial effect of adopting the above-mentioned further technical solution is to ensure that the molten metal flowing out of the exhaust channel flows directly into the collection tank.

[0019] Furthermore, each of the exhaust channels is inclined upwards at 10-15° from the inside out. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-7 As shown, this utility model discloses a pouring basin structure, including a pouring cup 1 and a liquid collecting ring 2. The lower part of the pouring cup 1 has multiple radially distributed venting channels 11. The pouring cup 1 is assembled in the interface 21 of the liquid collecting ring 2 to form a liquid collecting groove 3 between the pouring cup 1 and the liquid collecting ring 2. The outlet of each venting channel 11 corresponds to the position of the liquid collecting groove 3. On the one hand, this utility model allows for early observation of whether the molten metal fills the cavity 41 of the sand mold 4, timely judgment of whether casting is complete, avoiding the pouring cup 1 from being filled to the brim, and saving molten metal in the pouring cup 1. For castings weighing less than 50 kg, the molten metal in the pouring cup 1 is about 7.5 kg (calculated according to the density of cast steel parts). This saving can increase the casting yield by more than 5%. On the other hand, the multiple radially distributed venting channels 11 can increase the venting area, which helps the gas to be discharged in a specific direction and avoids turbulence.

[0030] Specifically, the pouring cup 1 is funnel-shaped; the interior of the pouring cup 1 has a conical hole 101 and a cylindrical hole 102 that are connected from top to bottom; a plurality of exhaust channels 11 are evenly arranged along the circumference of the cylindrical hole 102. In this embodiment, there are 6 exhaust channels 11, and the diameter of each exhaust channel 11 is 8mm.

[0031] Specifically, the lower part of the pouring cup 1, located below the exhaust channel 11, is in close contact with the interface 21 of the liquid collecting ring 2, thereby ensuring the sealing between the pouring cup 1 and the interface 21 of the liquid collecting ring 2 and preventing the molten metal in the liquid collecting tank 3 from leaking out from the interface 21 between the pouring cup 1 and the liquid collecting ring 2.

[0032] Specifically, each exhaust channel 11 is located at the same horizontal level as the liquid collection tank 3 to ensure that the molten metal flowing out of the exhaust channel 11 flows directly into the liquid collection tank 3.

[0033] Specifically, each exhaust channel 11 is inclined upwards at 10-15° from the inside to the outside to prevent molten metal from flowing into the collection tank 3 from the exhaust channel 11 when it is poured.

[0034] The casting method of this utility model includes the following steps:

[0035] The molten metal flows into the cavity 41 of the sand mold 4 through the pouring cup 1 (the bottom of the pouring cup 1 is aligned with the cavity 41). When the molten metal is found to flow out from the venting channel 11 (when the cavity 41 is filled, the molten metal flows back from the cavity 41 to the pouring cup 1, and flows out through multiple venting channels 11 to the liquid collection tank 3), the casting can be stopped at this time.

[0036] This invention can not only meet the requirements of casting, but also detect in time whether the molten metal has filled the mold cavity 41 to reduce the amount of molten metal used, and can also eliminate the gas generated during the casting process to improve the yield.

[0037] It is worth mentioning that this utility model is applicable to small castings (≤50kg), especially to gravity casting of metal materials such as cast steel, cast iron, and aluminum alloy.

[0038] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
