Description

Technical Field

[0001] This utility model relates to the field of casting system technology, and in particular to a vertical line casting system for a large vertical brake bracket. Background Technology

[0002] Large vertical brake brackets are typically manufactured horizontally, but producing smaller, lighter brackets horizontally results in low production efficiency and high costs. Therefore, vertical manufacturing is being considered.

[0003] The prior art, application number CN2023228986995, describes a casting mold for preventing the separation and deformation of automotive brake caliper brackets. Due to the different structure of the brackets, the brackets in the prior art are disc-shaped with a hollowed-out middle part. The production of large brackets by vertical lines has many hot spots in the casting, making it difficult to compensate for the bridge area in key areas. The design of the casting compensation process is also difficult, resulting in uneven casting wall thickness, thin-walled areas are prone to overcooling, and cold shut defects.

[0004] Therefore, it is necessary to design a large vertical brake support vertical line casting system to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a large vertical brake bracket vertical line casting system to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A large vertical brake support vertical casting system includes a pouring cup and horizontal runners vertically connected to the pouring cup and arranged on both sides. The system further includes: gradient vertical runners respectively connected to both sides of the horizontal runners and arranged vertically downwards; vertical brake support cavities respectively disposed above and below the gradient vertical runners; and riser access modules respectively connected to and communicating with the vertical brake support cavities. The riser access modules include components respectively connected to the outside of the gradient vertical runners on both sides. The system includes an upper riser inlet, an upper riser inlet connected to the upper riser inlet, a top riser connected to the top of the vertical brake support cavity, lower riser inlets connected to the outside of the gradient vertical gating channels on both sides, a lower riser inlet connected to the lower riser inlet, and an L-shaped insulating riser connected to the bottom of the vertical brake support cavity. A cooling plate is provided at the inner ring cavity position at the bottom of the vertical brake support cavity, and the cooling plate is provided corresponding to the L-shaped insulating riser.

[0008] Preferably, a vertical sprue slot is provided in the gradient vertical sprue, and the vertical sprue slot is located in the middle of the upper and lower vertical brake bracket cavities. The diameter of the sprue of the gradient vertical sprue decreases from the top to the bottom.

[0009] Preferably, the upper riser inlet is positioned above the upper riser inlet; the lower riser inlet is positioned below the upper riser inlet; and the lower riser inlet is positioned above the lower riser inlet.

[0010] Preferably, the top vent is located at the top of the vertical brake bracket cavity.

[0011] Preferably, the L-shaped insulating riser is placed on the side and bottom of the vertical brake bracket cavity.

[0012] Preferably, the ratio of the diameters of the gating cup, the horizontal gating, the gradient vertical gating, the upper and lower riser inlet gates, and the upper and lower riser inlets is 1.2:1.1:1:1.5.

[0013] The beneficial effects of this invention are as follows: This technical solution uses an integrated gating system to quickly fill the flow path, while ensuring a sufficiently smooth flow of molten iron into the mold cavity to avoid defects such as sand and slag inclusions. Furthermore, the combination of upper and lower risers with rapid cooling measures guarantees that the casting is free of shrinkage defects, resulting in higher overall production efficiency compared to horizontal casting.

[0016] Reference Figure 1 A large vertical brake support vertical line casting system includes a pouring cup 1, a horizontal runner 2 vertically connected to the pouring cup and arranged horizontally on both sides, a gradient vertical runner 4 connected to both sides of the horizontal runner 2 and arranged vertically downward, a vertical brake support cavity 10 respectively arranged in the upper and lower parts of the gradient vertical runner 4, and riser access modules respectively connected to the vertical brake support cavity 10.

[0017] A sprue slot 7 is provided inside the gradient vertical sprue 4, and the sprue slot 7 is positioned in the middle of the upper and lower vertical brake bracket cavities 10. The diameter of the sprue of the gradient vertical sprue 4 decreases from the top to the bottom. The gradient vertical sprue 4 can be quickly filled in the early stage of filling, avoiding sand holes caused by the molten iron heating the cavity. At the same time, it saves costs to a certain extent. The sprue slot 7 can control the filling sequence of the upper and lower mold cavities to ensure consistent filling and avoid defects such as cold shuts, air holes, and incomplete filling caused by inconsistent filling of the cavities.

[0018] The riser access module includes an upper riser inlet 6 connected to the outside of the gradient vertical gating channels 4 on both sides, an upper riser inlet 8 connected to the upper riser inlet 6, a top riser 3 connected to the top of the vertical brake bracket cavity 10, a lower riser inlet 61 connected to the outside of the gradient vertical gating channels 4 on both sides, a lower riser inlet 81 connected to the lower riser inlet 61, and an L-shaped heat-insulating riser 5 connected to the bottom of the vertical brake bracket cavity 10.

[0019] The upper riser inlet 6 is positioned above the upper riser inlet 8; the lower riser inlet 61 is positioned below the upper riser inlet 8; and the lower riser inlet 61 is positioned above the lower riser inlet 61.

[0020] The top riser 3 is placed at the top of the vertical brake bracket cavity 10; the top riser 3 can directly solve the shrinkage and porosity of the rough beam, while also taking into account the water inlet insulation at the top, ensuring that the overall temperature field of the casting is uniform and avoiding poor cold shut caused by uneven temperature.

[0021] The L-shaped heat-insulating riser 5 is placed on the side and bottom of the vertical brake bracket cavity 10; it can take into account the most important hot spots of the casting, the bridge section and the thin beam section, and the L-shape provides heat insulation for the bridge section and the thin beam section.

[0022] A cooling plate 9 is provided at the bottom inner ring cavity position of the vertical brake bracket cavity 10. The cooling plate 9 is set corresponding to the L-shaped heat preservation riser 5. The cooling plate 9 drives the hot section of the thin beam towards the riser. Finally, the two hot sections are carried into the riser, so that there are no defects in the two areas.

[0023] The ratio of the gating diameters of the pouring cup 1, horizontal gating 2, gradient vertical gating 4, riser inlet 6, and riser inlet 7 is 1.2:1.1:1:1.5, which ensures that the gating system can be filled quickly, while the opening ratio ensures that the molten iron entering the mold cavity is sufficiently smooth.

[0024] The advantages of this invention are that the integrated gating system quickly fills the flow path, while ensuring a sufficiently smooth flow of molten iron into the mold cavity to avoid defects such as sand and slag inclusions. Furthermore, the combination of upper and lower risers with rapid cooling measures guarantees that the casting is free of shrinkage defects, resulting in higher overall production efficiency compared to horizontal casting.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
