Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a casting with a sunken riser platform. Background Art

[0002] In a casting mold, risers are typically located on the top or side of the casting. The design and placement of risers are crucial to ensuring casting quality, as they directly impact the feeding efficiency and final quality of the casting. Riser design and placement adhere to a series of principles to ensure their effectiveness: Risers should be placed above the feeding area of ​​the casting or near the last hot spot to solidify, allowing for gravity-induced feeding. This ensures adequate feeding during solidification, preventing defects such as shrinkage cavities and porosity. Risers should be placed away from stress concentration areas within the casting to avoid cracking. Furthermore, riser design should take into account the shrinkage characteristics of the casting to avoid hindering its free shrinkage. When feeding hot spots at different heights, risers can be placed at different levels, with chills used to separate the feeding ranges of the risers to prevent shrinkage cavities in high-rise risers from extending into the casting. Furthermore, the shape and placement of risers should be tailored to the specific shape of the casting and the feeding requirements to ensure optimal casting quality and performance. During the design process, it is also necessary to consider how to conveniently remove the riser remnants.

[0003] In the prior art, the riser is generally on the upper surface of the casting. After the casting is completed and the riser is broken, there will be a riser platform protruding a certain height above the upper surface of the casting. Even if the upper surface of the casting does not need further processing in the later stage, the riser platform still needs to be removed by air gouging, grinding, turning, etc., which is difficult to clean, time-consuming and labor-intensive, and seriously affects the production efficiency of the casting.

[0020] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.

[0021] Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0022] like Figure 1 and Figure 2As shown, the utility model provides a casting with a sunken riser platform. The casting refers to the original casting whose riser 4 is not removed after sand falling. The structure of the original casting is used to show the structure of the sunken riser 4, so that the mold structure is adjusted accordingly for application to all castings with risers 4.

[0023] See also Figure 1 and Figure 2 The casting with a sunken riser platform includes a casting body 1, a riser platform 3 and a riser 4 connected in sequence. It should be noted that Figure 1 and Figure 2 The casting body 1 in the figure only represents one structural form. The present invention does not limit the casting body 1 and may be of other structural forms. The upper surface of the casting body 1 is provided with a sink 2 of a set depth, a riser table 3 is provided in the sink 2, and the first end of the riser 4 is connected to the riser table 3. Specifically, a sink 2 of a set depth is recessed at the position where the riser 4 is placed on the upper surface of the casting, and the riser 4 is placed on the bottom surface of the countersunk hole. When the riser 4 is hit, the broken end of the riser 4 is lower than the upper surface of the casting. The riser table 3 does not need to be cleaned by air planing, grinding, turning, etc. at a later stage, which greatly improves the production efficiency of the casting.

[0024] Preferably, during casting, the surface of the casting body 1 that does not require machining is generally used as the upper surface of the casting body 1 , further reducing the number of machining steps on the upper surface of the casting body 1 .

[0025] The depth of the sink 2 is 6 mm to 10 mm, preferably 8 mm, which can ensure that the height of the riser platform 3 is lower than the upper surface height of the casting body 1 and reduce the impact on the structure of the casting body 1.

[0026] like Figure 1 and Figure 2 As shown, the cross sections of the sink 2 , the riser platform 3 and the riser 4 are all circular, and the sink 2 , the riser platform 3 and the riser 4 are coaxially arranged.

[0027] Specifically, the riser platform 3 is truncated, with its lower surface connected to the bottom of the sink 2 and its upper surface connected to the first end of the riser 4. The upper surface of the riser platform 3 is no higher than the upper surface of the casting body 1, eliminating the need for later removal of the riser platform 3 by gouging, grinding, or turning, thereby reducing processing steps and improving production efficiency.

[0028] Furthermore, the riser 4 includes a cylindrical first section and an inverted truncated cone second section, which are sequentially connected to the riser platform 3. The second end of the riser 4 is connected to the riser platform 3 in an hourglass-shaped structure, which facilitates the removal of the riser 4.
