Description

Technical Field

[0001] The utility model relates to the technical field of brake caliper casting, in particular to a casting mould for an automobile brake caliper bracket. Background Art

[0002] The brake caliper bracket is an indispensable and important product in the parts of the automobile brake system. It is widely used in various models. It is an important component to ensure the safety of the car. Therefore, ensuring the quality of the brake caliper bracket can ensure the operation of a qualified brake system and the safe driving of a qualified vehicle.

[0003] At present, its production method is to produce blanks by casting, and then assemble them into the brake system assembly after machining. In order to ensure the normal operation of the brake system, the brake caliper bracket must withstand huge forces and long-lasting durability, so the appearance and internal sand slag hole defects of the casting are not allowed. At present, most of the existing brake caliper bracket casting molds adopt a double-sided insulation riser-runner direct flushing process layout on both sides of each caliper bracket casting cavity on the mold cavity. The insulation riser is set on the vertical runners located on both sides of the casting cavity. Such a layout process method is easy to cause turbulent sand flushing of molten iron when pouring molten iron, thereby forming sand slag holes in the casting, affecting the appearance and internal quality of the casting, and making the finished product rate of the casting low. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a casting mold for an automobile brake caliper bracket, which can effectively reduce the turbulent sand washing caused by molten iron when pouring molten iron into the casting, improve the appearance and internal quality of the casting, and effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting mold for an automobile brake caliper bracket, comprising a mold cavity, a casting cavity is arranged in the mold cavity, vertical runners are arranged on both sides of the casting cavity, the upper end of the vertical runner is connected to a second horizontal runner, the upper end of the second horizontal runner is connected to a pouring cup, a riser lap is arranged on the inner side of the vertical runner, and an insulation riser is arranged between the riser lap and the corresponding casting cavity.

[0006] As a preferred technical solution of the utility model, the casting cavities are arranged in three rows and two columns in the mold cavity.

[0007] As a preferred technical solution of the utility model, a first cross runner is arranged between the second cross runner and the pouring cup, and the first cross runner and the second cross runner are connected by a runner overlap piece.

[0008] As a preferred technical solution of the utility model, the riser laps are arranged at equal intervals on the inner side of the vertical runner, and the insulation riser is located at the top of the casting cavity, and the riser laps are located below the insulation riser.

[0009] As a preferred technical solution of the utility model, the center lines of the two rows of casting cavities coincide with the center line of the pouring cup.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the casting mold of the automobile brake caliper bracket is reasonably designed and ingeniously conceived. It is optimized on the basis of the conventional double-sided riser process layout, so that the inner sides of the vertical runners on both sides are connected to the insulation risers through the riser lap plates, and then the insulation risers are connected to the inside of the casting cavity. The molten iron flow rate is controlled by the lap plates to ensure uniform water inflow when pouring molten iron, reduce molten iron turbulence and sand washing caused by pouring molten iron into the casting, and thus improve the appearance and internal quality of the casting.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0014] See also Figure 1 The utility model provides a technical solution: a casting mold for an automobile brake caliper bracket, comprising a mold cavity, wherein three rows and two columns of casting cavities 8 are arranged in the mold cavity, vertical runners 5 are arranged on both sides of the casting cavity 8, the upper end of the vertical runner 5 is connected to the second horizontal runner 4, the upper end of the second horizontal runner 4 is connected to the pouring cup 1, a riser lap piece 6 is arranged on the inner side of the vertical runner 5, and an insulation riser 7 is arranged between the riser lap piece 6 and the corresponding casting cavity 8. After the molten iron is diverted by the lap piece 6 and the flow rate is controlled, the molten iron enters the insulation riser 7 in equal amounts before entering the casting cavity, which effectively avoids the sand blasting, improves the appearance and internal quality of the casting, and thus improves the yield rate.

[0015] Furthermore, a first horizontal runner 2 is arranged between the second horizontal runner 4 and the pouring cup 1, and the first horizontal runner 2 is connected to the second horizontal runner 4 by a runner lap 3. By arranging the first horizontal runner 2 and the runner lap 3, the impact force of the molten iron entering the vertical runner 5 can be reduced, thereby facilitating the control of the flow rate of the molten iron.

[0016] Furthermore, the riser laps 6 are arranged at equal intervals on the inner side of the vertical runner 5, and the insulation riser 7 is located at the top of the casting cavity 8, and the riser laps 6 are located below the insulation riser 7. By entering the insulation riser 7 from the riser laps 6 below, the impact force and flow rate of the molten iron can be further controlled, ensuring that the flow rate of the molten iron into the casting cavity 8 is uniform, and reducing the occurrence of molten iron turbulence and sand washing.

[0017] Furthermore, the center lines of the two rows of casting cavities 8 coincide with the center line of the pouring cup 1, ensuring that the flow rate and impact force of the molten iron are evenly distributed after diversion.

[0018] When in use: the molten iron enters the first horizontal runner 2 through the pouring cup 1, and then enters the second horizontal runner 4 through the runner lap 3, is diverted into the vertical runner 5 through the second horizontal runner 4, and then is diverted into the inner riser lap 6 through the vertical runner 5, enters the insulation riser 7 from the riser lap 6, and finally enters each casting cavity 8 through the insulation riser 7.
