Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically to a casting mold for a support blank. Background Technology

[0002] According to patent authorization announcement number CN118720063A, a casting mold for an automotive brake caliper bracket is disclosed, relating to the field of casting mold technology. Its key technical points are: a base with legs fixedly connected to its bottom, a material hole for unloading the external caliper bracket inside the base, and a mold section including a first slide rail. A concave mold is slidably mounted on the inner side of the first slide rail, and a mold cover is provided above the concave mold. A limiting member that tightly fits the outer surface of the mold cover is provided on the side of the first slide rail. This automotive brake caliper bracket casting mold effectively solves the problem in the prior art where, during the casting of automotive brake caliper brackets, after the casting has completely solidified, it needs to be carefully removed from the mold. This step generally requires workers to use appropriate tools and techniques to ensure smooth demolding of the caliper bracket and prevent external forces from acting on it during the demolding process.

[0003] However, there are problems with the existing technology: the limiting component adopts a semi-circular arc structure design, and its core functional requirement is to achieve large-angle rotation. However, due to the geometric characteristics of the arc structure, the arc contact surface is prone to uneven force when rotating at a large angle, and the arc gap is difficult to control precisely, which makes it very easy to jam in actual operation. Frequent jamming will also increase the frequency and cost of maintenance, reduce the overall operating efficiency of the equipment, and have an adverse impact on the continuity of production.

[0015] 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.

[0016] Please see Figure 1-3 A casting mold for a bracket blank includes a base plate 1, a workbench 2 fixedly connected to the top of the base plate 1, a concave mold 3 provided on the top of the workbench 2, the left side of the concave mold 3 being movably connected to the right side of the inner wall of the workbench 2, a mold cover 4 being movably connected to the top of the concave mold 3, connecting blocks 5 being fixedly connected to the front and rear sides of the mold cover 4, a round rod 6 being fixedly connected to the bottom of the connecting block 5, a positioning sleeve 7 being sleeved on the surface of the round rod 6, the inner side of the positioning sleeve 7 being fixedly connected to the front and rear sides of the concave mold 3, a tension spring 8 being fixedly connected to the bottom of the positioning sleeve 7, the other side of the tension spring 8 being fixedly connected to the bottom of the round rod 6, and a feeding mechanism being provided on the right side of the top of the workbench 2.

[0017] Please see Figure 1-3 The unloading mechanism includes a mounting frame 91, which is fixedly connected to the right side of the top of the workbench 2. A rotating frame 92 is movably connected inside the mounting frame 91. A motor 93 is fixedly connected to the front side of the mounting frame 91. The output end of the motor 93 is fixedly connected to the front side of the mounting frame 91. The top and bottom of the rotating frame 92 are located at the bottom of the die 3 and the top of the mold cover 4, respectively.

[0018] Furthermore, by setting the pad block 10, the cavity mold 3 and the mold cover 4 can be automatically pushed to open and close, replacing manual operation, reducing labor intensity, and ensuring the stability and consistency of the opening and closing action, thus reducing molding errors.

[0019] Please see Figure 1-3 A pad 10 is fixedly connected to the top of the mold cover 4, and the pad 10 is located inside the rotating frame 92.

[0020] Furthermore, by setting pulley 11, the direct contact between the rotating frame 92 and the mold cover 4 is avoided, thus preventing wear and extending the service life of the mold cover 4. At the same time, it ensures efficient transmission of power by the rotating frame 92 and guarantees smooth opening and closing actions.

[0021] Please see Figure 1-3 The top of the pad block 10 is provided with a pulley 11, which is movably connected to the top of the rotating frame 92. The bottom of the die 3 is provided with a pulley 12, which is movably connected to the bottom of the rotating frame 92.

[0022] Furthermore, by setting pulley 2 12, the sliding friction between the rotating frame 92 and the pad block 10 and the die 3 is converted into rolling friction, which greatly reduces the motion resistance, reduces the energy consumption of the motor 93, and at the same time reduces component wear and improves the overall durability of the mold.

[0023] Please see Figure 1-3 The front and rear sides of the top of the worktable 2 are fixedly connected with limiting blocks 13, and the surface of the limiting blocks 13 is in contact with the surface of the die 3.

[0024] Furthermore, by setting the limiting block 13, the die 3 is prevented from shifting during operation, ensuring the docking accuracy between the die 3 and the mold cover 4, and improving the forming quality of the bracket blank.

[0025] Please see Figure 1-3 A water tank 14 is fixedly connected to the top left side of the base plate 1, and the water tank 14 is located on the left side of the bottom of the cavity mold 3.

[0026] Furthermore, the water tank 14 facilitates the cooling of the molded die 3, accelerates the solidification of the blank, shortens the production cycle, and collects cooling wastewater to keep the working environment clean.

[0027] The specific implementation process of this utility model is as follows: When in use, the concave mold 3 and the mold cover 4 are in a sealed closed state. After the support blank inside the concave mold 3 is formed, the motor 93 is started. The motor 93 drives the rotating frame 92 to rotate. The rotating frame 92 drives the pulley 11 and pulley 22 to move upward in an arc shape. The pulley 212 pushes the concave mold 3 and the mold cover 4 to rotate. At the same time, pulley 11 and mold cover 4 separate, and mold cover 4 loses its pressing effect. The tension of spring 8 drives the round rod 6 to move upward. The round rod 6 drives the connecting block 5 and mold cover 4 to rotate upward. During the process of the die 3 flipping and tilting, mold cover 4 automatically opens. When the die 3 rotates to a certain angle, the bracket blank formed inside the die 3 falls into the interior of water tank 14.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
