Technical Field

[0001] The utility model belongs to the technical field of casting production, and particularly relates to a mold of an anti-collision inner gate structure of an ADI bracket. Background Art

[0002] Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used to cast some parts with complex stresses and high requirements for strength, toughness and wear resistance. Molds are required when casting ductile iron.

[0003] Existing casting molds generally have an inner gate and a casting cavity. The gate is connected to the inside of the casting cavity. When pouring, the castable material enters the cavity through the gate when the mold formed by the mold is poured. During the casting process, the liquid outlet of the ladle needs to be aligned with the inner gate. The operation is difficult during the movement and alignment of the ladle, and bumps often occur, which damages the inner gate.

[0004] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0025] like Figure 1As shown, a mold of an anti-collision inner gate structure of an ADI bracket includes an upper template 1, a lower template 5, and an inner gate 6. The upper template 1 is a square metal plate. An upper mold 2 is provided in the middle of the upper template 1. The lower end surface of the upper mold 2 is provided with a cavity groove. The lower template 5 is directly opposite to the upper template 1. A lower mold 4 is provided in the middle of the lower template 5 to match the upper mold 2. The upper end surface of the lower mold 4 is provided with a cavity groove corresponding to the upper mold 2. The upper template 1 and the lower template 5 are relatively moved by a driving mechanism, so that the upper mold 2 and the lower mold 4 are docked with each other to form two casting cavities 3. The casting cavity 3 is formed. The cavity 3 is used for casting the ADI bracket. A casting hole is provided in the middle of the upper template 1, the upper mold 2 and the lower mold 4. The casting hole is located in the center of the mold and extends downward to the upper surface of the lower mold 4. The upper mold 2 and the lower mold 4 are fixed to the upper template 1 and the lower mold 5 respectively by bolts. Two runners 7 extending to the two casting cavities 3 are provided on the side of the casting hole. The ends of the runners 7 are connected to the casting cavity 3 through a smooth hole with a reduced inner diameter for injecting molten steel. The inner gate 6 extends into the casting hole. The inner gate 6 is a rotating body adapted to the casting hole. A center hole is provided in the middle of the inner gate 6. The lower end of the inner gate 6 is a closed end, and the center hole extends to the lower end of the inner gate 6. There are two connecting holes 12 adapted to the runners 7. The connecting holes 12 correspond to the two runners 7 one by one. At least one stepped platform with an increased outer diameter is provided above the inner gate 6. Correspondingly, a stepped hole corresponding to the upper end of the casting hole is provided on the upper template 1, so that the inner gate 6 is axially positioned through the stepped hole. A buffer spring 9 is provided at the lower end of the inner gate 6. In the non-casting state, the inner gate 6 is not fully extended into the casting hole under the drive of the spring 9. When docking with the ladle outlet 11, the ladle outlet 11 presses down the ingating gate 6. As the ladle mouth squeezes the ingating gate 6 downward, the ingating gate 6 overcomes the elastic force of the spring 9 to make the lower surface of the stepped platform contact the upper template 1. At this time, the connecting hole 12 is opposite to the runner 7 and connected to the casting cavity 3. In this embodiment, the upper end of the center hole of the ingating gate 6 is a V-shaped mouth or a conical mouth, and the corresponding ladle liquid outlet 11 is set to a cone adapted thereto to ensure the fit between the two and improve the sealing performance, thereby ensuring the docking of the ladle liquid outlet 11 with the ingating gate 6, and when the ingating gate 6 is not fully positioned, the molten steel does not flow downward, thereby avoiding the molten steel from spilling.

[0026] In an optional embodiment, the ingrate 6 includes two equally divided parts spliced ​​together. After the casting is completed, the ingrate 6 is taken out upward to clean the center hole inside the ingrate 6 to ensure the quality of the secondary casting. In this embodiment, the splicing seam of the two equally divided parts passes through the axis of the two connecting holes 12, thereby ensuring that the residual molten steel can be completely cleaned.

[0027] In an optional embodiment, in order to accurately position the inner gate 6, a slide bar extending axially is provided on the outside of each equally divided part. The slide bar is located on the outer wall of the columnar part of the inner gate 6, and a corresponding strip groove is provided in the casting hole, thereby positioning the inner gate 6 and ensuring accurate alignment of the runner 7 and the connecting hole 12.

[0028] Furthermore, a plurality of guide columns 10 are provided below the upper template 1, and there are four guide columns 10. The lower template 5 is provided with guide holes that are compatible with the guide columns 10; or a plurality of guide columns 10 are fixed above the lower template 5, and the guide columns 10 are slidably assembled on the upper template 1. In actual production, in order to drive, the lower template 5 or the lower template 5 is fixed on the base, and a hydraulic cylinder is provided between the upper template 1 and the lower template 5, so as to drive the two so that the two can be spliced ​​together or moved away from each other.

[0029] In an optional embodiment, a riser 8 is provided on the upper edge of the casting cavity 3 away from the runner 7. The riser 8 extends obliquely to the outer wall of the mold. The riser 8 extends obliquely upward to be higher than the highest point of the casting cavity 3. The joint seam of the upper mold 2 and the lower mold 4 passes through the center line of the runner 7 and the riser 8 respectively, so that the molded workpiece can be quickly removed after the upper and lower molds 4 are separated.

[0030] In an optional embodiment, a positioning ring is provided on the lower template 5 for sleeve connection with the upper mold 2, and a stepped hole corresponding to the upper mold 2 is provided on the upper edge of the inner hole of the positioning ring, and a stepped platform corresponding to the stepped hole is provided on the upper edge of the upper mold 2, so as to ensure the connection strength between the upper mold 2 and the upper template 1 and improve the connection stability.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
