[0002] In V-process casting (vacuum-sealed molding), the design and placement of risers are crucial to casting quality, especially for high-requirement materials such as ductile iron. Risers must simultaneously meet the needs of feeding, heat preservation, and venting. However, traditional processes in the negative pressure environment of the V-process suffer from drawbacks such as insufficient oxygen supply, the risk of high-temperature splashing, and poor installation stability.

[0003] To address the aforementioned issues, a novel V-process ductile iron insulation riser placement device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a novel V-process ductile iron insulation riser placement device to solve the problems mentioned in the background art.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0016] Please see Figure 1-4 This utility model provides a novel V-process ductile iron insulation riser placement device, including an annular mounting boss 1, an insulation riser 2 at the top of the annular mounting boss 1, a venting riser 3 fixedly mounted at the top of the insulation riser 2, a second annular reinforcement 5 fixedly mounted at the connection between the annular mounting boss 1 and the insulation riser 2, a first annular reinforcement 4 fixedly mounted at the bottom of the surface of the insulation riser 2, a third annular reinforcement 6 fixedly mounted at the top of the surface of the venting riser 3, a plurality of evenly distributed first reinforcing strips 7 fixedly mounted between the third annular reinforcement 6 and the second annular reinforcement 5, and a plurality of evenly distributed second reinforcing strips 8 fixedly mounted between the first annular reinforcement 4 and the second annular reinforcement 5. The first reinforcing strips 7 are all fixedly connected to the venting riser 3, and the second reinforcing strips 8 are all fixedly connected to the insulation riser 2. The first annular reinforcement 4 and the second annular reinforcement 5... The third annular reinforcement 6, several first reinforcing strips 7, and several second reinforcing strips 8 are all made of stainless steel. This device adds a venting riser 3 to the normal use of the insulation riser 2, and sets a corresponding annular mounting boss 1 at the connection between the insulation riser 3 and the main body. The addition of the boss, while ensuring the shrinkage compensation effect, separates the riser from the product body. Several positioning brackets 9 are engaged with several positioning slots 11 to facilitate the initial connection between the insulation riser 2 and the annular mounting boss 1. Several connecting pins 12 are engaged with several connecting blocks 10 to facilitate the further stable connection between the insulation riser 2 and the annular mounting boss 1. The coordinated arrangement of the first annular reinforcement 4, the second annular reinforcement 5, the third annular reinforcement 6, several first reinforcing strips 7, and several second reinforcing strips 8 can improve the overall structural strength and make it more durable.

[0017] In this embodiment, the insulating riser 2 is installed at the top of the annular mounting boss 1 and is one of the core components of the entire process. It is made of special insulating material and has excellent heat insulation performance, effectively reducing heat loss during the solidification process of the casting. During ductile iron casting, the insulating riser 2 provides sufficient feeding molten metal to the casting, preventing defects such as shrinkage cavities and porosity. Its shape and size are optimized according to the structure of the casting and feeding requirements. For example, for ductile iron castings with uneven wall thickness, the size of the insulating riser 2 will be increased accordingly to ensure sufficient feeding capacity. The venting riser 3 is fixedly installed at the top of the insulating riser 2. The main function of the venting riser 3 is to expel gas from the mold cavity during pouring, preventing gas from forming porosity defects in the casting. It has a suitable venting cross-sectional area, ensuring smooth gas discharge without affecting the filling of the molten metal. The internal structure design of the vent riser 3 also facilitates gas guidance and discharge. For example, the gradually narrowing channel shape allows the gas to gradually accelerate during discharge. The first annular reinforcement 4, the second annular reinforcement 5, the third annular reinforcement 6, several first reinforcing strips 7, and several second reinforcing strips 8 are all made of stainless steel. Stainless steel has excellent corrosion resistance, effectively preventing rust and corrosion of the reinforcements in the high-temperature and humid environment of ductile iron casting, thus extending their service life. At the same time, stainless steel also has good strength and toughness, capable of withstanding the large stress and impact generated during casting, ensuring that the reinforcements do not deform or break during long-term use, thereby providing reliable support and reinforcement for the insulation riser and the vent riser.

The diameter of the top opening of the warm riser 2 is the same as the diameter of the bottom opening of the venting riser 3. This device adds a venting riser 3 on the basis of the normal use of the warm riser 2, and sets a corresponding annular mounting boss 1 at the connection between the warm riser 3 and the main body. The addition of the boss, under the premise of ensuring the shrinkage compensation effect, separates the riser from the product body. The initial connection between the warm riser 2 and the annular mounting boss 1 is facilitated by the limiting engagement of several positioning brackets 9 with several positioning slots 11. The further stable connection between the warm riser 2 and the annular mounting boss 1 is facilitated by the limiting engagement of several connecting brackets 12 with several connecting brackets 10. The overall structural strength can be improved by the cooperation of the first annular reinforcement 4, the second annular reinforcement 5, the third annular reinforcement 6, several first reinforcing strips 7 and several second reinforcing strips 8, making it more durable.

[0019] In the embodiments of this application, the vent riser 3 is reasonably designed with a suitable venting cross-sectional area and internal structure, which can ensure the smooth discharge of gas in the cavity. At the same time, the reinforced structure ensures the stability of the vent riser during the venting process, preventing damage to the vent riser or poor venting due to gas impact, thereby avoiding porosity defects in the casting.
