[0014] The utility model is a box-poking machine used in conjunction with a two-layer circulating cooling line. Figure 1-4 As shown, it includes a fixed frame 1, which serves as the basis and installation frame of the entire device. A horizontally arranged casing moving plate 2 is installed in the fixed frame 1. One end of the casing moving plate 2 is connected to the second-layer circulating cooling line, and the other end of the casing moving plate 2 is provided with a casting drop port 3. A cleaning mechanism is installed on the fixed frame 1 on the upper side of the casting drop port 3, and a casing moving mechanism is installed on the fixed frame 1 on the upper side of the casing moving plate 2.

[0015] The second-tier circulating cooling line is equipped with several casings 4, each open at the top and bottom. These casings are filled with sand and castings. A trolley is located at the bottom of each casing 4 to provide support and movement while in the circulating cooling line. A casing moving mechanism transfers the casings 4 on the second-tier circulating cooling line to the bottom of a cleaning mechanism, which pushes downward to clean loose sand from the casing's inner walls. The cleaning mechanism also features a prying function, which can pry castings downward from the casings, allowing them to be removed from the casings.

[0016] The casing moving plate 2 acts as a guide plate, allowing the casing 4 to be positioned on it and be driven by the casing moving mechanism to the drop opening 3. At this time, the bottom of the casing 4 opening is matched with the drop opening 3, and the cleaning mechanism moves downward to poke the castings in the casing 4 downward to obtain the castings. Before moving to the drop opening 3, the casing moving plate 2 is set to prevent the sand mold and castings inside the casing 4 from falling and separating.

[0017] In order to realize the dropping of the casting, the cleaning mechanism includes a vertical cylinder 5 installed on the fixed frame 1, and a cleaning plate 6 is installed at the bottom of the piston rod of the vertical cylinder 5. The cleaning plate 6 is located at the upper part of the casting drop port 3 and matches the opening position of the casing 4. The piston rod of the vertical cylinder 5 is in a retracted state when not in operation, and the cleaning plate 6 is located at the upper side of the casing 4, which does not affect the normal movement of the casing 4 and the casing moving mechanism. When the casing 4 is brought to the ejection station of the casting drop port 3, the piston rod of the vertical cylinder 5 extends downward, and the cleaning plate 6 moves downward synchronously to push the sand tire and the casting in the casing 4 downward together, completing the sand removal operation.

[0018] When the casing 4 is moved to the casting drop opening 3, the sand mold and casting inside it can be removed by gravity. A cleaning mechanism clears loose sand from the inner wall of the casing 4 and also functions as a prying mechanism to ensure that the casing 4 at the casting drop opening 3 can be removed. The casing 4 is not an internal component of the prying mechanism; it serves as a separate transport and loading device to transfer, transport, and cool the sand mold and casting.

[0019] To ensure that the casting ejection operation does not interfere with the normal operation of the cooling circulation line, the cooling circulation line and the ejection station are located at both ends of the casing moving plate 2, and the casing 4 is transported by the casing moving mechanism. The casing moving mechanism includes a traveling frame 7 that can move on the fixed frame 1. Clamping devices are installed on both sides of the bottom of the traveling frame 7. The clamping devices can complete the clamping and synchronous movement of the casing 4. The clamping devices can be existing clamping manipulators or clamping cylinders, which can achieve the clamping, fixation and grasping movement of the casing 4.

[0020] Furthermore, in order to facilitate the separation of the casing 4 from the bottom traveling trolley and to more securely grab and transfer the casing 4, as shown in FIG. Figure 5-Figure 8As shown, the clamping device includes a connecting plate 13 mounted at the bottom of the traveling frame 7. Two rows of horizontally arranged clamping wheels 14 are mounted on the inner side of the connecting plate 13. A horizontally mounted positioning cylinder 15 is also mounted on the connecting plate 13. Clamping plates 16 are provided on both sides of the sleeve 4 to mate with the clamping wheels 14. Guide ramps 17 are provided at each end of the lengthwise direction of the clamping plates 16. A positioning pin is mounted on the piston rod of the positioning cylinder 15. Positioning holes 18 that mate with the positioning pin are also provided on the side of the sleeve 4. The piston rod of the positioning cylinder 15 extends, driving the positioning pin into the positioning hole 18 of the sleeve 4, thereby positioning the sleeve.

[0021] The traveling frame 7 is located at the upper side of the cooling circulation line. When the traveling trolley on the cooling circulation line drives the casing 4 to move, the guide ramp 17 will first cooperate with the clamping wheels 14 arranged side by side, and as the traveling trolley and the casing 4 gradually move, the clamping plate 16 will enter between the clamping wheels 14, so that the casing 4 is lifted a certain height and separated from the traveling trolley. After that, the piston rod of the positioning cylinder 15 extends into the positioning hole 18 to clamp the casing 4. The traveling trolley can continue to stay on the cooling circulation line, and the casing 4 can be grabbed and driven to the casting discharge station.

[0022] Furthermore, in order to allow the traveling frame 7 to move more stably on the fixed frame 1 and to control the distance of movement more accurately, so as to ensure that the sleeve 4 can cooperate to move to the designated drop port 3 position to realize the casting removal operation, a horizontally arranged moving groove 8 is installed on the fixed frame 1, and moving wheels 9 that match the moving groove 8 are installed on both sides of the traveling frame 7. A power motor 10 is also installed on the traveling frame 7, and a gear 11 is installed on the output shaft of the power motor 10. A rack 12 that meshes with the gear 11 is installed on the fixed frame 1. When the power motor 10 is started, it can drive the traveling frame 7 to move horizontally. Through the transmission of the matching moving groove 8 and moving wheels 9, and the meshing gears 11 and racks 12, not only can the stable movement of the entire traveling frame 7 be achieved, but the moving distance of the traveling frame 7 can also be accurately controlled to ensure the feasibility of subsequent casting removal.

[0023] When the casing 4 with the sand tire moves on the casing moving plate 2, the sand tire inside it will be scattered onto the casing moving plate 2, affecting the normal movement of the subsequent casing 4. In order to clean the sand that has fallen on the casing moving plate 2 to ensure the normal movement of the subsequent casing 4, a sand scraping plate 19 is installed at the lower end of the clamping device. The sand scraping plate 19 is located on the upper side of the casing moving plate 2. When the casing moving mechanism moves to the upper side of the casing moving plate 2, the sand scraping plate 19 contacts the casing moving plate 2. During the reciprocating movement of the casing moving mechanism, the sand scraping plate 19 can effectively scrape the casing moving plate 2 to prevent the remaining sand on it from interfering with the normal movement of the casing 4.

[0024] Furthermore, in order to enable the cleaning plate 6 to be lifted and lowered vertically more stably and realize the pushing-out operation of the sand tire and casting inside the casing 4, the vertical movement cylinder 5 is installed on the fixed frame 1 through the connecting seat 20, and a vertically arranged guide rod 21 is installed on the cleaning plate 6. The connecting seat 20 is provided with a guide sleeve 22 that cooperates with the guide rod 21. The matching guide sleeve 22 and the guide rod 21 can make the cleaning plate 6 more stable when it contacts the sand tire for vertical lifting and lowering, and no lateral deviation will occur, thereby ensuring that the cleaning plate 6 can smoothly enter the casing 4 to push out the casting.

[0025] Furthermore, in order to increase the strength of the entire fixing frame 1 , reinforcing ribs 23 arranged in a staggered manner are installed on the fixing frame 1 .

[0026] The technical solution of the present invention is not limited to the scope of the embodiments described in the present invention. The technical contents not described in detail in the present invention are all well-known technologies.
