Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sand core disc production process, and more specifically, to a sand core disc transfer device. Background Technology
[0002] Sand core discs (or sand core plates) are commonly used in the foundry industry, especially in metal casting processes. They are core molds made of sand (usually sand, clay, resin, etc.) used to create cavities during the casting process. These cavities are typically used to create complex internal structures or holes, and are commonly found in castings requiring precise shapes and high quality. Sand core discs often experience very high temperatures during casting and retain these temperatures even after casting is completed. Strong impacts or direct transport to the next process can easily cause damage due to the excessive temperature, requiring additional time for inspection or replacement and slowing down the production cycle. Therefore, specialized cooling and transfer devices are necessary. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0019] like Figure 1-2As shown, this utility model discloses a sand core tray transfer device, including a frame 7. Two slide rails 2 are connected to the upper end of the frame 7. A support base 9 is slidably connected to the upper end of each slide rail 2. The lower end of the support base 9 is connected to the output end of a first cylinder 4 via a push plate 8. Two feeding slide rods 1 are provided on the upper surface of the support base 9. One end of each feeding slide rod 1 is rotatably connected to a support shaft 10 on the upper surface of the support base 9, and the other end is supported on the upper end of the support base 9 via a support block. On the right side of the push plate 8, a second cylinder 5 is connected. The output end of the second cylinder 5 is connected to two picking rods. The picking rods include a picking part 11-1 on the left and a picking part 11-2 on the right. A third cylinder 3 is also connected to the lower end of the support base 9. A connecting rod 12 is connected between the two feeding slide rods 1. The output end of the third cylinder 3 is connected to the middle of the connecting rod 12. A T-shaped shelf 6 is connected to the right end of the slide rail 2. Example 1:
[0020] In practical use, the first cylinder 4 pushes the support base 9 to the right via the push plate 8, and the picking rod follows, moving to the right until the second picking part 11-2 extends to the preset position one. At this time, the output end of the second cylinder 5 lifts the picking rod (picking part 11-2) to the preset position two, and the cast first sand core disc enters the second picking part 11-2. The output end of the first cylinder 4 retracts to its original position, and then the output end of the second cylinder 5 retracts to its original position, and the first sand core disc is placed on the shelf 6 for cooling. When the second sand core disc is cast, the first cylinder 4 pushes the support base 9 to the right via the push plate 8, and the picking rod follows, moving to the right until the second picking part 11-2 extends to the preset position two. When position one is reached, the output end of the second cylinder 5 lifts the picking rod to the preset position two. At this time, the first sand core disc, after cooling, will fall into the picking section 11-1, while the second sand core disc, which is hotter, will enter the picking section 21-2. The output end of the first cylinder 4 retracts to its original position, and then the output end of the second cylinder 5 retracts to its original position. The second sand core disc, which is hotter, will then be placed on the shelf 6 for cooling, while the first sand core disc will be placed on the unloading slide bar 1. Finally, the output end of the third cylinder 3 lifts the connecting rod 12 upward, causing the right end of the unloading slide bar 1 to tilt upward. The first sand core disc then slides from the unloading slide bar 1 onto the conveyor belt and is sent to the next process. The above steps are repeated.
[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
