Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting, in particular to a caliper bracket sand core which is anti-dumping and anti-collision. Background Art
[0002] During the production and manufacturing process of the caliper body casting, caliper bracket sand cores are required. During the production and transportation process, the existing caliper bracket sand cores are tilted due to structural reasons, resulting in varying degrees of shaking, which in turn causes friction and collision between the sand cores and between the sand cores and the partitions, leading to damage. After the casting is formed, it will cause the product to have multiple defects and be scrapped, affecting the product yield. Summary of the Invention
[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a caliper bracket sand core that is anti-dumping and anti-collision.
[0004] The specific scheme of the utility model is: a caliper bracket sand core that is anti-dumping and anti-collision, including a sand core body, the lower end of the sand core body is provided with a main core head and two lower supporting feet, the bottom surface of the main core head and the bottom surfaces of the two lower supporting feet are located in the same horizontal plane, and the lines connecting the three fulcrums are arranged in a triangle; the upper end of the sand core body is provided with a secondary core head and two upper supporting feet, the top surface of the two upper supporting feet and the top surface of the secondary core head are located in the same horizontal plane, and the lines connecting the three vertices are arranged in a triangle.
[0005] Furthermore, the upper supporting leg and the corresponding lower supporting leg are arranged in the same vertical plane.
[0006] Furthermore, the upper supporting foot is arranged at the highest point of the sand core body, and the lower supporting foot is arranged at the lowest point of the sand core body.
[0007] Furthermore, the main core head is arranged at the highest point of the bottom surface of the sand core body, and the auxiliary core head is arranged at the lowest point of the top surface of the sand core body.
[0008] Furthermore, the main core head and the auxiliary core head are arranged in the same vertical plane.
[0009] Compared with the existing technology, the utility model has the following advantages: the main core head and the two lower supporting feet are combined to form a three-legged support structure, which can effectively ensure that the sand core will not tilt after being placed, and at the same time completely isolate the sand core body from the lower support plate of the sand core; at the same time, the auxiliary core head and the two upper supporting feet are combined to form a three-legged support structure, which can effectively support the upper sand core after stacking and completely isolate the sand core body from the upper support plate of the sand core, thereby ensuring that the sand core is in a stable state after stacking, avoiding bumps and damages on the sand core body, and thus ensuring the stable quality of the products made.

[0016] See also Figure 1-5 The present embodiment is a caliper bracket sand core that is anti-tilting and anti-collision, including a sand core body. The lower end of the sand core body is provided with a main core head 5 and two lower supporting legs 4. The bottom surface of the main core head and the bottom surfaces of the two lower supporting legs 4 are located in the same horizontal plane, and the three supporting points are arranged in a triangular shape; the upper end of the sand core body is provided with a secondary core head 2 and two upper supporting legs. The top surfaces of the two upper supporting legs and the top surface of the secondary core head 2 are located in the same horizontal plane, and the three vertices are arranged in a triangular shape.
[0017] Furthermore, the upper supporting leg and the corresponding lower supporting leg 4 are arranged in the same vertical plane.
[0018] Furthermore, the upper supporting foot is arranged at the highest point of the sand core body, and the lower supporting foot 4 is arranged at the lowest point of the sand core body.
[0019] Furthermore, the main core head 5 is arranged at the highest point of the bottom surface of the sand core body, and the auxiliary core head is arranged at the lowest point of the top surface of the sand core body.
[0020] Furthermore, the main core head 5 and the auxiliary core head 2 are arranged in the same vertical plane.
[0021] The utility model provides a tripod support structure on the upper and lower sides of the sand core body 1 to prevent tipping. During transportation, a plastic partition is placed after a layer of sand cores is full, and then the second layer is placed, so that each layer can be placed stably and will not shake during transportation, reducing damage, thereby avoiding the occurrence of fleshy defects and resulting in scrap in casting production, and improving the product yield.
