Description

Technical Field

[0001] This utility model belongs to the field of casting mold technology, specifically relating to a brake caliper casting mold with a thin sheet connected to a Y-shaped vertical runner. Background Technology

[0002] Brake calipers are a crucial component of a car's suspension system. Deformation of them can significantly impact vehicle assembly efficiency and safety. High production volumes and high scrap rates for brake calipers lead to increased production costs.

[0003] Currently in the casting industry, due to the inherent structure of brake caliper castings, sand holes and slag holes are unavoidable. For export products, the processing standards are high, resulting in a wide variety of machining defects. Our company currently uses DISA231 vertical line wet film sand casting for brake calipers. The existing mold plate size is 650*525mm. Due to the design dimensions of the casting itself, and to ensure the product's appearance and internal quality, a layout of 4 pieces per mold is generally used. This requires multiple risers to meet the requirements, resulting in multiple riser necks in the casting, increasing workload, affecting molten iron utilization, and reducing production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to design a brake caliper casting mold with thin sheet connection Y-shaped vertical runner, so as to solve the problems of low iron utilization and low production efficiency mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a brake caliper casting mold with a thin sheet connecting a Y-shaped vertical runner, comprising a pouring cup, a horizontal runner, a riser, a thin sheet A, a Y-shaped vertical runner, a thin sheet B, a thin sheet C, and a casting cavity. The pouring cup is located at the center of the top of the mold, and the lower end of the pouring cup is connected to the middle of the horizontal runner. A riser is provided below both ends of the horizontal runner. The upper ends of the Y-shaped vertical runner are connected to both sides of the middle of the horizontal runner through the thin sheet A. The Y-shaped vertical runner is located in the middle of the mold. A casting cavity is provided between the Y-shaped vertical runner and the riser. The inner side of the casting cavity is connected to the Y-shaped vertical runner, and the outer side of the casting cavity is connected to the riser. Thin sheets B and C are provided on the passage between the Y-shaped vertical runner and the casting cavity.

[0006] The thin sheet A is connected between the horizontal runner and the Y-shaped vertical runner by means of reverse overlap, which is used to enhance the slag-avoiding ability of the Y-shaped vertical runner and make the Y-shaped vertical runner and the horizontal runner easier to separate.

[0007] The thin plates B and C are spaced apart in the passage between the Y-shaped vertical runner and the casting cavity, which further prevents slag from entering the cavity of the molten iron, thereby eliminating the intermediate riser, reducing the loss of molten iron, and making it easier to separate the Y-shaped vertical runner from the casting cavity.

[0008] The thickness of sheet A is 3mm, the thickness of sheet B is 5mm, and the thickness of sheet C is 3mm.

[0009] The beneficial effects of this invention are: it increases the slag-avoiding capacity of the gating system; through three layers of filtration, it effectively reduces the generation of sand and slag holes in the calipers, improves the product's process yield and quality, and saves on the cost of manual casting separation. This lays a solid foundation for the future mass production of high-quality automotive calipers. Attached Figure Description

[0012] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] Please see Figure 1A brake caliper casting mold with a Y-shaped vertical runner connected by thin sheets includes a pouring cup 1, a horizontal runner 2, a riser 8, a thin sheet A4, a Y-shaped vertical runner 3, a thin sheet B5, a thin sheet C6, and a casting cavity 7. The pouring cup 1 is located at the center of the top of the mold, and its lower end is connected to the middle of the horizontal runner 2. The riser 8 is provided below both ends of the horizontal runner 2. The upper ends of the Y-shaped vertical runner 3 are connected to both sides of the middle of the horizontal runner 2 through the thin sheet A4. The Y-shaped vertical runner 3 is located in the middle of the mold. A casting cavity 7 is provided between the Y-shaped vertical runner 3 and the riser 8. The inner side of the casting cavity 7 is connected to the Y-shaped vertical runner 3, and the outer side of the casting cavity 7 is connected to the riser 8. Thin sheets B5 and C6 are provided on the passage between the Y-shaped vertical runner 3 and the casting cavity 7. The thin sheet A4 is connected to the junction of the horizontal sprue 2 and the Y-shaped vertical sprue 3 via a reverse overlap, enhancing the slag-avoiding ability of the Y-shaped vertical sprue 3 and facilitating its separation from the horizontal sprue 2. Thin sheets B5 and C6 are spaced apart in the passageway between the Y-shaped vertical sprue 3 and the casting cavity 7, further preventing slag from entering the casting cavity 7, thereby eliminating the intermediate riser, reducing molten iron loss, and also facilitating the separation of the Y-shaped vertical sprue 3 from the casting cavity 7. The thickness of thin sheet A4 is 3mm, the thickness of thin sheet B5 is 5mm, and the thickness of thin sheet C6 is 3mm.

[0014] During the use of this utility model: Molten iron is poured from the pouring cup 1 into the mold and flows into the horizontal sprue 2. Part of the molten iron enters the casting cavity 7 through the riser 8 at both ends of the horizontal sprue 2, while the other part passes through the thin sheet A4 for initial slag removal and then enters the Y-shaped vertical sprue 3 through its top. After further slag removal through thin sheets B5 and C6, it enters the casting cavity 7. This eliminates the need for the existing intermediate riser in the mold, reduces the weight of the gating system, improves product yield, and reduces casting sand content. The use of thin sheet A4 increases the slag-avoiding ability of the Y-shaped vertical sprue 3 and connects it to the back of the horizontal sprue 2 in a reverse lap joint manner, making it easier to separate the Y-shaped vertical sprue 3 from the horizontal sprue 2. Thin sheets B5 and C6 further filter the molten iron, reducing the formation of sand holes and slag holes in the casting. This solution not only improves the slag-avoiding ability but also saves molten iron and reduces the labor costs caused by separating castings after removing the intermediate riser, thereby achieving the goal of saving labor costs and improving product yield.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
