[0018] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0019] The following is combined with Figure 1 The utility model is described in further detail.

[0020] The embodiment of the utility model discloses a horizontal pouring device.

[0021] Reference Figure 1 A horizontal pouring device includes a pouring device, a pouring platform, a pouring cavity 6, and a riser. The pouring device is used to pass pouring liquid into the pouring cavity 6 through the pouring platform, and multiple pouring liquids enter the riser through the pouring cavity 6. The pouring cavity 6 is horizontally arranged on the pouring platform. The horizontal pouring of the casting ensures good stability during the pouring process, effectively avoiding conflicts and contradictions between the stability of the mud core in the middle cavity during the mold assembly and pouring process and the riser setting and shrinkage compensation, which may cause excessive wall thickness or shrinkage defects in the casting.

[0022] The casting cavity 6 includes a core, which is hollow in the center and is placed on the casting platform. Core Structure: The core, also known as the mold core, is a crucial component used to form the internal structure of the casting during casting. It is typically made from raw sand and a binder, and is formed in a core box. The core is hollow in the center to accommodate the flow and solidification of the casting liquid during the casting process.

[0023] The core maintains a stable position during the pouring process to prevent displacement due to the impact of the pouring liquid, which could affect the dimensional accuracy and shape of the casting. The accuracy and tightening force during the mold assembly process prevent the core from shifting or deforming during the pouring process. The core is placed on the pouring table and works with the pouring device to ensure that the pouring liquid can fill the mold smoothly, reducing oxidation and the generation of inclusions.

[0024] The casting platform includes a transition ingate 4, through which the casting device directs the casting liquid into the casting cavity 6. In this embodiment, the casting platform supports and secures the casting cavity 6 during the casting process, ensuring a smooth casting process. The transition ingate 4 connects the casting device to the casting cavity 6, allowing the casting liquid to enter the cavity through the transition ingate 4, completing the casting process.

[0025] The casting table also includes a bottom pouring reverse shower gate 5, and the casting device sequentially passes the casting liquid through the transition shower gate 4 and the bottom pouring reverse shower gate 5 into the casting cavity 6. The reverse shower casting gives full play to the slag blocking and collecting ability of the casting system, and effectively controls the slag and sand inclusion defects of the casting. The casting liquid is injected into the casting table by the bottom pouring method, that is, from the bottom of the mold cavity, and enters the casting cavity 6 through the reverse shower gate before entering the casting cavity 6. The reverse shower design can give full play to the slag blocking and collecting ability of the casting system, and effectively control the slag and sand inclusion defects of the casting. The casting liquid flows smoothly, and inclusions and gases are easy to float out, reducing casting defects.

[0026] The riser includes an open riser 7, which is arranged at the top of the casting cavity 6. The open riser 7 provides a cavity for the molten metal used to feed the casting, and has the functions of preventing shrinkage cavities, shrinkage porosity, exhausting gas, and collecting slag. The open riser 7 is arranged at the top of the casting cavity 6 and is connected to the atmosphere, which has good exhaust and slag removal effects.

[0027] The longitudinal section formed between the transition ingates 4 and the bottom pouring anti-drenching ingates 5 is T-shaped. The T-shaped longitudinal section design can ensure that the pouring liquid can be smoothly diverted into the bottom pouring anti-drenching ingates 5 after passing through the transition ingates 4. This smooth flow helps to reduce turbulence and eddy currents in the pouring liquid, thereby reducing oxidation and the generation of inclusions. The bottom pouring anti-drenching ingates 5 has the ability to block and collect slag. When forming a T-shaped connection with the transition ingates 4, the ability to block and collect slag is further enhanced. Inclusions and slag in the pouring liquid are more easily blocked and collected near the ingates when passing through the T-shaped ingates, thereby reducing the inclusions entering the interior of the casting. The T-shaped ingates design also has a better shrinkage compensation effect. During the casting process, the pouring liquid will shrink in volume during the cooling and solidification process. The T-shaped ingates can ensure that when the casting needs to be compensated for shrinkage, the pouring liquid can be timely and fully replenished into the casting, thereby reducing the generation of defects such as shrinkage cavities and shrinkage porosity.

[0028] The riser includes blind seam risers 8, which are arranged on the transition ingates 4. Specifically, the blind seam risers 8 are arranged on both sides of the transition ingates 4. When the casting liquid passes through the transition ingates 4, it will partially enter the blind seam risers 8, providing shrinkage feeding and slag collection for the casting. Because the blind seam risers 8 are not connected to the atmosphere, they can reduce oxidation and air absorption of the casting liquid, thereby improving the quality of the casting. In addition, the blind seam design allows the casting liquid to more smoothly feed the casting during solidification, reducing the occurrence of defects such as shrinkage cavities and shrinkage porosity.

[0029] The riser includes a spherical blind riser 9, which is arranged on the outer contour of the casting cavity 6, and the upper plane of the spherical blind riser 9 is located between the upper plane of the blind seam blind riser 8 and the upper plane of the visible riser 7. The shape of the spherical blind riser 9 is close to spherical. The spherical blind riser 9 is connected to the outer surface of the casting, but is not directly connected to the atmosphere, which helps the spherical blind riser 9 to better play a shrinkage compensation role and reduce the oxidation and air intake of the casting liquid. The spherical blind riser 9 has a large shrinkage compensation capacity and a good slag collection effect. Since it is not connected to the atmosphere, it can reduce the air intake phenomenon of the casting during the solidification process, thereby improving the quality of the casting. In addition, the spherical design also helps the casting liquid to more smoothly compensate for the shrinkage of the casting during the solidification process, reducing the occurrence of casting defects.

[0030] By rationally arranging the open riser 7, the spherical hidden riser 9 and the gap hidden riser, the shrinkage cavity and shrinkage defects in the thick and large parts of the casting are controlled, effectively solving the shrinkage cavity and shrinkage defects in the thick and large parts of the casting.

[0031] A shaped chill 10 is provided between the bottom of the casting cavity 6 and the bottom pouring anti-rain shower gate 5. The solidification sequence of the casting is achieved by the chilling effect of the chill. The shaped chill 10 is a metal block with a specific shape and size, which is placed at the bottom of the casting cavity or near the gate. The high thermal conductivity and large heat capacity of the metal block are utilized to absorb and take away a large amount of heat during the solidification process of the casting, thereby accelerating the solidification rate of the casting in this part, helping the shaped chill 10 to better exert its chilling effect and control the order in which the casting gradually solidifies from the bottom to the top. In addition, the shaped chill 10 can also support the casting and prevent deformation and cracks. During the casting process, the cooling and solidification of the casting liquid will generate shrinkage force, and the presence of the shaped chill 10 can provide a certain support force to prevent the casting from deforming or cracking during the solidification process.

[0032] In this embodiment, the pouring device includes a sprue 1 and a runner 2, through which the pouring liquid enters the casting cavity 6. Specifically, during pouring, the pouring liquid flows through the sprue 1, the filter screen, the runner 2, the transition gate 4, and the anti-rain gate into the casting cavity.

[0033] A filter device 3 is provided between the sprue 1 and the runner 2. In this embodiment, the filter device 3 is a filter mesh. The provision of the filter device 3 between the sprue 1 and the runner 2 can effectively purify the casting liquid. Removing inclusions: The filter device 3 can capture and retain non-metallic inclusions, such as slag, refractory material flakes, etc., to prevent them from entering the interior of the device. Reducing secondary oxidation: By reducing the turbulence of the molten metal in the device, the filter device 3 helps to reduce secondary oxidation, thereby preventing the formation of oxides, and can increase the density of the casting, thereby improving its mechanical properties.

[0034] In this embodiment, molten copper is used as the casting liquid.

[0035] The utility model can obtain a casting with good internal quality and an external profile and size that meet technical requirements.
