A bearing cover casting mold

Abstract

This utility model relates to the field of bearing cover casting technology, and in particular to a bearing cover casting mold, including a support plate and a casting mold runner disposed on the support plate. The casting mold runner includes a main gating and several auxiliary gatings perpendicularly connected to the main gating. One end of each auxiliary gating is provided with several casting modules arranged in series and vertically. Each casting module includes a flow-limiting ingate and a mold in the shape of a bearing cover. The mold is connected to both sides of the flow-limiting ingate. One end of the flow-limiting ingate is provided with a sprue, and one end of the sprue is connected to another casting module. In this utility model, molten iron is poured in from the main gating. The diameter of the flow-limiting ingate is larger than the diameter of the sprue. The molten iron flows into the molds on both sides of the flow-limiting ingate and slowly flows into the next casting module. This not only allows multiple bearing covers to be cast at once, but also prevents impurities from being deposited in the sprue recess during the casting process, thus minimizing the mixing of impurities and molten iron and resulting in better quality bearing covers after casting.

Description

Technical Field

[0001] This utility model relates to the field of bearing cover casting technology, and in particular to a bearing cover casting mold. Background Technology

[0002] Bearing caps prevent dust, moisture, or other impurities from entering the bearing, thus maintaining the cleanliness and working environment of the bearing, ensuring its normal operation, and extending its service life.

[0003] The bearing cap is formed by casting using a mold. Molten iron is poured into the mold and cooled to form the shape. In existing technology, the mold is often placed parallel to the table. This method is only suitable for casting round bearing caps. If a semi-circular bearing cap is cast, the cross-section of the semi-circular bearing cap is perpendicular to the table. During the casting process, the molten iron is easy to flow back from the inlet end of the mold. At the same time, since there are some tiny impurities in the molten iron, a large number of impurities will mix with the molten iron during casting, which will reduce the quality of the cast bearing cap. Utility Model Content

[0004] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a bearing cover casting mold, which not only facilitates the casting of bearing covers, but also increases the casting quality of bearing covers.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A bearing cap casting mold includes a support plate and a casting runner disposed on the support plate. The casting runner includes a main runner and several secondary runners perpendicularly connected to the main runner. Several casting modules are disposed at one end of each secondary runner. Each casting module includes a flow-limiting ingate and a mold in the shape of a bearing cap. The mold is connected to both sides of the flow-limiting ingate. A sprue is disposed at one end of the flow-limiting ingate, and one end of the sprue is connected to another casting module.

[0007] Preferably, the diameter of the sprue is smaller than the diameter of the flow-limiting ingate.

[0008] Preferably, a riser is provided on the flow-limiting ingate, the riser is raised and the riser is connected to the flow-limiting ingate.

[0009] Preferably, the casting module also includes a direct gating system, which is connected to the flow-limiting ingate located at the bottom.

[0010] Preferably, a direct pouring channel recess is provided at one end of the final pouring channel, the direct pouring channel recess is protruding on the support plate, and the direct pouring channel recess and the final pouring channel are connected.

[0011] Preferably, a voltage stabilizing tube is provided on the support plate, with one end of the voltage stabilizing tube connected to the injection mold and the other end connected to the outside of the support plate.

[0012] This utility model has the following advantages and beneficial effects:

[0013] In this invention, molten iron is poured into the main gating system and flows into multiple flow-limiting ingates. The diameter of the flow-limiting ingates is larger than the diameter of the sprue. The molten iron flows into the molds on both sides within the flow-limiting ingates and slowly flows into the next casting mold. This not only allows for the casting of multiple bearing caps at once, but also ensures that impurities are deposited in the sprue recesses during the casting process, minimizing the mixing of impurities and molten iron and resulting in better quality bearing caps after casting.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Example

[0021] like Figure 1-3As shown, a bearing cover casting mold includes a support plate 1 and a casting channel disposed on the support plate 1. The support plate 1 is perpendicular to the table. The casting channel includes a main gating 2 and several auxiliary gating channels 3 perpendicularly connected to the main gating 2. Molten iron is poured in from the main gating 2 and flows into the several auxiliary gating channels 3. Several casting modules are disposed at one end of the auxiliary gating channels 3. In this utility model, two sets of casting modules are provided, including casting module IA and casting module IIB. Casting module IA and casting module IIB are arranged vertically in series, which can cast multiple bearing covers C at one time, increasing casting efficiency.

[0022] like Figure 1-3 As shown, the casting mold assembly includes a flow-limiting ingate 4, a C-shaped mold 5 (bearing cap), and a sprue 7. The mold 5 is connected to both sides of the flow-limiting ingate 4 and is connected to the ingate 4. A sprue 6 is provided at one end of the flow-limiting ingate 4. Casting mold assembly IA and casting mold assembly IIB are connected by the sprue 6. The diameter of the sprue 6 is smaller than the diameter of the flow-limiting ingate 4, and the flow diameter of the mold 5 is larger than the diameter of the sprue 6. When molten iron flows into the flow-limiting ingate 4, a large amount of molten iron will flow into the mold 5, filling the mold 5, while some molten iron will flow out from the sprue 6. The molten iron enters the casting module IIB. A riser 41 is provided on the flow-limiting ingate 4. The riser 41 is raised and connected to the flow-limiting ingate 4. Since the volume of molten iron will shrink after solidification, the riser 41 is provided to ensure that there is enough fluid molten iron to compensate for shrinkage and prevent the size of the cast bearing cover C from becoming smaller. A pressure stabilizing pipe 9 is provided on the support plate 1. One end of the pressure stabilizing pipe 9 is connected to the injection mold 5, and the other end is connected to the outside of the support plate 1. The pressure stabilizing pipe 9 is embedded in the support plate 1. During the casting process, gas is discharged from the upper end of the support plate 1 to prevent the internal gas pressure from increasing during the casting process.

[0023] like Figure 1-3 As shown, the final gating channel 7 is connected to the casting mold IIB and communicates with the flow-limiting ingate 4 located at the bottom. One end of the final gating channel 7 is provided with a gating channel recess 8, and the gating channel recess 8 is connected to the final gating channel 7. The gating channel recess 8 is protruding on the support plate 1. Since the molten iron contains impurities, after setting the gating channel recess 8, when the molten iron is poured into the casting mold, it will fall from the flow-limiting ingate 4 in the casting mold IIB into the gating channel 6 under the influence of its own gravity, then fall from the gating channel 6 into the flow-limiting ingate 4 in the casting mold IIB, then fall from the flow-limiting ingate 4 into the final gating channel 7, and finally fall into the gating channel recess 8. The impurities are deposited in the gating channel recess 8, which can prevent the impurities from mixing with the molten iron during the casting process, so that the quality of the cast bearing cover C is not up to standard.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
