[0009] An operating body, the operating body comprising a base, a leg being fixedly connected to the bottom of the base, and a material hole for unloading materials from an external clamp support being provided inside the base;

[0010] The mold part includes a first slide rail, a die is slidably installed on the inner side of the first slide rail, a mold cover is arranged above the mold, and a limiter is arranged on the side of the first slide rail, which is tightly fitted with the outer surface of the mold cover and is used for the external clamp body bracket to rotate smoothly to unload the material.

[0011] Furthermore, it also includes a buffer part, which includes a base, and the base is connected to a placement plate via a telescopic rod arranged on the top, and the interior of the telescopic rod is filled with a strong spring.

[0012] Furthermore, a buffer rubber pad is provided on the upper surface of the placement plate, the placement plate is located directly below the material hole, and the diameter of the placement plate is greater than the diameter of the material hole.

[0013] Furthermore, a feed port communicating with the space enclosed by the die and the die cover is provided above the die cover, and the die cover and the die are rotatably mounted via a hinge assembly.

[0014] Furthermore, it also includes a reinforcement part, which includes a bracket, the bottom of the bracket is fixedly connected to the top of the base, the internal damping rotation of the bracket is connected to a reinforcement rod, and the reinforcement rod is slidably installed with a reinforcement plate that fits tightly with the lower surface of the die through a built-in groove opened on its circumferential outer surface.

[0015] Furthermore, an L-shaped block connected to the outer surface of the bracket is arranged on the side of the first slide rail away from the die, a return spring connected to the inside of the reinforcement rod is arranged inside the reinforcement plate, and an adjustment rod connected to the internal thread of the reinforcement rod is rotatably installed inside the reinforcement plate.

[0016] Furthermore, the reinforcement rod is fixedly connected to a magnetic block via a special-shaped rod arranged at an outer end thereof, and the bracket is fixedly connected to an electromagnetic block attracted to the magnetic block via a support plate arranged on an outer surface thereof.

[0017] Furthermore, the limiting member includes a second slide rail, the outer side of the second slide rail is fixedly connected to the outer surface of the material hole, the inner side of the second slide rail is slidably connected to a limiting plate, and the lower side edge of the limiting plate is fixedly connected with a convex edge.

[0019] Beneficial Effects

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] The present invention is provided with a mold part and a buffer part. When the casting is completely solidified, the first slide rail is energized to drive the die and the mold cover to perform circular motion along the inner wall thereof. When the die and the mold cover perform circular motion between 20 and 30 degrees, the outer surfaces of the die and the mold cover will contact the convex edge and the limit plate respectively. Subsequently, the convex edge and the limit plate will synchronously perform circular rotation motion with the die and the mold cover, and the slide plate will limit the convex edge and the limit plate to prevent the convex edge and the limit plate from rotating on their own, thereby ensuring that the mold cover is always in contact with the outer surface of the die during the downward rotation of the die and the mold cover. When the die and the mold cover rotate to the bottom, the convex edge will first detach from the smooth plate, and then the limit plate will also detach from the smooth plate. Under the action of gravity, the limit plate and the convex edge will freely swing downward with the help of the rotating axis. At the same time, the limiting effects of the limiting plate and the convex edge on the mold cover disappear, and the mold cover, under the action of gravity, overcomes the magnetic force between the die and the mold cover and rotates downward. Subsequently, the solidified clamp body bracket automatically falls vertically onto the placement plate to complete automated unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The operating body 1 includes a base 11, a leg 12 is fixedly connected to the bottom of the base 11, and a material hole 13 for unloading materials from the external clamp support is opened inside the base 11;

[0037] The buffer part 3 also includes a base 31. The base 31 is connected to a placement plate 33 via a telescopic rod 32 arranged on the top. The interior of the telescopic rod 32 is filled with a strong spring to play a buffering role. At the same time, it is convenient for the clamp body bracket to quickly take out materials.

[0038] A buffer rubber pad is provided on the upper surface of the placement plate 33 for protecting the clamp body bracket. The placement plate 33 is located directly below the material hole 13. The diameter of the placement plate 33 is larger than the diameter of the material hole 13, which facilitates the smooth detachment of the clamp body bracket.

[0039] A feed port 231 communicating with the space enclosed by the die 22 and the die cover 23 is provided above the die cover 23 , and the die cover 23 and the die 22 are rotatably mounted via a hinge assembly.

[0040] It also includes a reinforcement part 4, which includes a bracket 41. The bottom of the bracket 41 is fixedly connected to the top of the base 11. The internal damping rotation of the bracket 41 is connected to a reinforcement rod 42. The reinforcement rod 42 is slidably installed with a reinforcement plate 43 that fits tightly with the lower surface of the die 22 through a built-in groove opened on its circumferential outer surface.

[0041] An L-shaped block 211 connected to the outer surface of the bracket 41 is arranged on the side of the first slide rail 21 away from the die 22, a return spring 431 connected to the inside of the reinforcement rod 42 is arranged inside the reinforcement plate 43, and an adjustment rod 44 connected to the internal thread of the reinforcement rod 42 is rotatably installed inside the reinforcement plate 43.

[0042] The reinforcing rod 42 is fixedly connected to a magnetic block 422 via a special-shaped rod 421 arranged at an outer end thereof, and the bracket 41 is fixedly connected to an electromagnetic block 412 attracted to the magnetic block 422 via a support plate 411 arranged on an outer surface thereof.

[0043] The limiting member 24 includes a second slide rail 241 , the outer side of the second slide rail 241 is fixedly connected to the outer surface of the material hole 13 , the inner side of the second slide rail 241 is slidably connected to a limiting plate 242 , and a convex edge 243 is fixedly connected to the lower side of the limiting plate 242 .

[0044] A smooth slide plate 244 close to the outer surface of the limiting plate 242 is fixedly connected between adjacent surfaces of a pair of second slide rails 241 , and the outer surfaces of the concave mold 22 and the mold cover 23 are in contact with the outer surface of the convex edge 243 .

[0045] refer to Figure 1-7 Casting is a common manufacturing method, which is to pour molten metal into a mold and form parts of the desired shape after cooling. When the automobile brake caliper bracket is manufactured by casting, when the casting is completely solidified, it needs to be removed from the mold. This step requires careful operation. Generally, workers need to use appropriate tools and techniques to ensure that the caliper bracket can be demolded smoothly to prevent the caliper bracket from being subjected to external forces during the demolding process.

[0046] In order to overcome the above-mentioned defects, the present invention designs a casting mold for an automobile brake caliper bracket.

[0047] Casting process:

[0048] Initially, the mold cover 23 on the mold part 2 is located directly above the die 22, and the mold cover 23 and the die 22 are in an attracted state, and there is magnetic attraction between the two. Then, the molten metal is poured into the feed port 231, and flows into the space surrounded by the die 22 and the mold cover 23. After cooling, a part of the desired shape (brake caliper body bracket) is formed. When the caliper body bracket is manufactured by casting, when the casting is completely solidified, it needs to be removed from the die 22. This step requires careful operation (to avoid high temperature burns) to prevent the caliper body bracket from being damaged during the demolding process.

[0049] Automated unloading process:

[0050] In practical applications, when the casting is completely solidified, it is necessary to remove it from the die 22. At this time, the first slide rail 21 is energized to drive the die 22 and the die cover 23 to perform circular motion along its inner wall (the range of motion is the stroke range of the first slide rail 21). When the die 22 and the die cover 23 perform circular motion between 20 and 30 degrees, the outer surfaces of the die 22 and the die cover 23 will contact the convex edge 243 and the limit plate 242 respectively. Subsequently, the convex edge 243 and the limit plate 242 will synchronously perform circular rotational motion with the die 22 and the die cover 23, the limit plate 242 slides along the inner side of the second slide rail 241, and the smooth plate 244 limits the convex edge 243 and the limit plate 242 to prevent the convex edge 243 and the limit plate 242 from rotating, ensuring that the die cover 23 always fits the outer surface of the die 22 during the downward rotation of the die 22 and the die cover 23, and preventing the clamp body bracket from automatically detaching after solidification.

[0051] When the die 22 and the die cover 23 rotate downward, the convex edge 243 will first detach from the smooth plate 244, and then the limit plate 242 will also detach from the smooth plate 244. Under the action of gravity, the limit plate 242 and the convex edge 243 will freely swing downward with the help of the rotating shaft. At the same time, the limit of the limit plate 242 and the convex edge 243 on the die cover 23 disappears, and the die cover 23 also overcomes the magnetic force between the die 22 and the die cover 23 under the action of gravity and rotates downward. Then, the solidified clamp body bracket automatically falls vertically onto the placement plate 33 to complete the automatic unloading, which can not only avoid high temperature burns for workers, but also effectively avoid friction between the clamp body bracket and the die 22 when demolding.

[0052] Automated reset process:

[0053] After the clamp body bracket automatically unloads the material, the first slide rail 21 drives the die 22 and the die cover 23 to start moving upward synchronously. Since the die cover 23 is in a drooping state, when the die 22 drives the die cover 23 to rotate upward, the die cover 23 moves toward one side of the die 22 under the action of the smooth plate 244 until the die 22 and the die cover 23 are at the top. At this time, the die cover 23 is separated from the smooth plate 244 under the action of gravity, and the automatic closing of the cover is realized, eliminating the trouble of manual resetting.

[0054] Subsequently, the second slide rail 241 is energized to drive the limit plate 242 to rotate upward along its interior. When the limit plate 242 contacts the smooth plate 244, under the action of the smooth plate 244, the limit plate 242 is driven to rotate clockwise and reset until the limit plate 242 and the convex edge 243 are moved to the outer surface of the smooth plate 244 for the next round of unloading of the subsequent die 22 and the die cover 23.

[0055] It should be emphasized in the present application that the concave die 22 and the die cover 23 will bear the gravity of the clamp body bracket during the casting process. In order to improve the service life and stability of the concave die 22 and the die cover 23, the present application is also equipped with a reinforcement 4, which has the following advantages:

[0056] Advantage 1: The reinforcing rod 42 and the reinforcing plate 43 are located directly below the die 22 , which bears the weight of the die 22 , improves the stability of the die 22 , and avoids strong wear between the die 22 and the first slide rail 21 .

[0057] Advantage 2: By rotating the adjusting rod 44 , the reinforcing plate 43 can be driven to slide along the inside of the reinforcing rod 42 for a short distance, so that a close fit between the reinforcing plate 43 and the concave mold 22 is achieved.

[0058] Advantage three: the reinforcing rod 42 and the bracket 41 are connected in a damped rotational connection. When the die 22 performs a circular motion, the reinforcing plate 43 and the reinforcing rod 42 can rotate counterclockwise synchronously with the die 22, so that the outer surface of the reinforcing plate 43 and the lower surface of the die 22 can be quickly separated to avoid excessive wear of the two.

[0059] Advantage four, when the die 22 rotates, the reinforcement plate 43 and the reinforcement rod 42 will rotate with it at a small angle. When the die 22 rotates and resets, the electromagnetic block 412 is energized, and the magnetic force acts on the magnetic block 422, driving the reinforcement plate 43 and the reinforcement rod 42 to quickly reset, so that the reinforcement plate 43 can be pressed against the lower surface of the die 22 again.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
