[0022] See Figures 1-4 The present invention provides a shuttle-type pressing device, which includes: The system comprises: a support frame 1 with a mold pressing area; a mold input structure 2 for inputting a casting box into the mold pressing area; a mold moving mechanism 3 for placing the mold onto the casting box; a mold pressing mechanism 4 for applying pressure to the mold; a mold dragging mechanism 5 for separating the pressurized mold from the casting box; and a mold output mechanism 6 for outputting the pressurized casting box from the mold pressing area. The mold input structure 2 first transports the casting box to be processed into the mold pressing area of ​​the support frame 1. Then, the mold moving mechanism 3 moves to accurately place the mold into the preset position on the casting box. Next, the mold pressing mechanism 4 applies a set, stable pressure to the mold, completing the mold pressing operation. Afterward, the mold dragging mechanism 5 moves to detach the pressurized mold from the casting box. Finally, the mold output mechanism 6 outputs the pressurized casting box from the mold pressing area, completing the entire mold pressing process.

[0023] In some embodiments of the present invention, the mold pressing area includes an upper area 7 and a lower area 8; the box-dragging mechanism 5 is disposed in the upper area 7; two sets of mold moving mechanisms 3 are provided, respectively disposed on one side of the upper area 7 and the lower area 8, with the upper mold and lower mold respectively placed in the upper and lower mold moving mechanisms 3. The box-pressing input structure 2 is connected to one side of the lower area 8, and the box-pressing output mechanism 6 is connected to one side of the upper area 7. To complete one box-pressing operation, firstly, the upper casting box enters the equipment through the box-pressing input structure 2, the lower mold moving mechanism 3 moves and engages the upper mold with the upper casting box, the mold pressing mechanism 4 applies pressure, and after pressure is applied, the mold rises to the upper area 7 by the lifting platform, the box-dragging mechanism 5 separates the mold, and the upper casting box is output through the box-pressing output mechanism 6. Subsequently, the lower casting box enters the equipment, and the above operations are completed in the same way.

[0024] In some embodiments of the present invention, the mold pressing mechanism 4 includes: a pressing component 9, including a base with a mounting portion and an output end extending / retracting from the base; a pressure block is mounted on the output end, and the pressing component 9 drives the pressure block closer to the casting box working area; the pressing component 9 can be a cylinder, a hydraulic cylinder, or an electric push rod, and the mounting portion is fixedly mounted on the pressing component frame to ensure the installation stability of the pressing component 9. By extending the output end of the pressing component 9, the pressure block can be moved toward the casting box located within the casting box working area to complete the pressing operation of the molding sand in the casting box. The mounting portion is installed at one end of the pressing component frame close to the casting box working area. This installation makes the side of the pressing component frame away from the casting box working area an open structure, which will not obstruct the arrangement of related operating components, making it convenient for operators to adjust the pressing component 9 from this side. At the same time, the installation position close to the casting box working area can also shorten the extension stroke of the output end of the pressing component 9, improving the efficiency and stability of the pressing operation.

[0025] In some embodiments of the present invention, an auxiliary frame 11 is provided on the support 1, and the auxiliary frame 11 is located on the side of the pressing part frame away from the working area of ​​the casting box; the auxiliary frame 11 and the pressing part frame are connected by a support rod 12. The auxiliary frame 11 can position the end of the seat away from the mounting part, preventing the non-mounting end of the seat from shaking or shifting during the operation of the pressing component 9, further improving the stability of the pressing block movement during pressing operations, and ensuring that the uniformity and compaction of the molding sand pressing meet production requirements. Meanwhile, the auxiliary frame 11 is only located on the open side of the pressing part frame away from the working area of ​​the casting box, thus not obstructing the loading and unloading operations of the casting box. This retains the advantage of the open structure, facilitating operation and adjustment. The support rod 12 connects the auxiliary frame 11 to the pressing part frame as a whole, which also improves the structural strength of the entire pressing mechanism to a certain extent. Specifically, the auxiliary frame 11 is connected to the end of the seat away from the working area of ​​the casting box. The auxiliary frame 11 is connected to the end of the seat to maximize the positioning and limiting effect on the non-installation end of the seat. Alternatively, the seat can pass through the auxiliary frame 11 and be located in its middle position.

[0026] In some embodiments of the present invention, multiple sets of support rods 12 are provided between the auxiliary frame 11 and the pressing part frame; protective components are provided between the connected support rods 12. To ensure an open space structure, multiple sets of support rods 12 are provided between the auxiliary frame 11 and the pressing part frame; protective components are provided between the connected support rods 12. Importantly, the protective components are detachable. This structure can protect the cylinder seat, preventing debris from accidentally falling into the area between the auxiliary frame 11 and the pressing part frame during operation. Simultaneously, the detachable protective components facilitate easy disassembly for inspection and maintenance of internal components, allowing for troubleshooting and component replacement without altering the overall structure, thus meeting the design requirements of an open structure for convenient maintenance.

[0027] In some embodiments of the present invention, the area of ​​multiple mold contact elements 10 distributed along the edge of the mold is smaller than that of the mold contact element 10 in the middle position. When the sand box arrives at the pressure area of ​​the mold, each pressure-applying element drives the corresponding mold contact element 10 to extend in the direction closer to the mold. The mold contact element 10 with a smaller size at the edge position provides greater pressure according to the applied pressure. The mold contact element 10 at the edge position contacts the edge of the sand box first, and then the mold contact element 10 with a larger area in the middle contacts the middle area of ​​the sand box to complete the pressure application. Compared with the traditional uniformly sized pressure block structure, the mold contact element 10 with a larger area in the middle can increase the pressure application area in the middle, disperse the pressure stress in the middle, and avoid cracking in the middle of the sand mold due to excessive pressure stress concentration. At the same time, the pressure block with a smaller area at the edge can ensure the locking pressure effect on the edge of the sand box and avoid sand overflow at the edge, thus ensuring the overall molding quality of static pressure molding.

[0028] In some embodiments of the present invention, the output end is provided with a mounting base, and the mold contact 10 is detachably fixed to the mounting base. The detachable structural connection facilitates the replacement of mold contact 10 of different sizes according to the actual sand box specifications and pressure requirements, flexibly adjusts the pressure area at different positions, adapts to the production requirements of different molding processes, and also facilitates the individual replacement of worn mold contact 10, reducing maintenance costs.

[0029] In some embodiments of the present invention, the trailer mechanism 5 includes: The demolding component 13, mounted on the bracket 1, has a movable output end. When the casting box reaches the predetermined position, the output end of the demolding component 13 moves to contact the mold placed on the casting box. The demolding component 13 is fixed to the upper part of the frame, with its output end facing the lifting platform. When the first power component drives the lifting platform to raise the casting box to the correct position, the top of the mold contacts the output end of the demolding component 13. Subsequently, the lifting platform moves the casting box downward, and the demolding component 13 holds the mold in place, allowing the mold to separate naturally from the casting box, completing the demolding action. This eliminates the need for manual mold separation, simplifying the demolding process.

[0030] In some embodiments of the present invention, a buffer head 14 is provided at the end of the bracket that contacts the mold, so as to absorb the vibration and impact generated by the demolding action during the descent of the casting box.

[0031] The buffer head 14 can be made of elastic and wear-resistant material, which can buffer the instantaneous impact force between the demolding part 13 and the mold when they come into contact, so as to avoid the mold from being deformed or damaged due to rigid collision. It can also reduce the noise generated during demolding. At the same time, the buffer head 14 itself has a certain structural strength and will not fail prematurely due to long-term repeated impact, thus ensuring the stability of the demolding action.

[0032] In other embodiments of the present invention, the end of the bracket that contacts the mold has a receiving cavity; the buffer head 14 is movably mounted in the receiving cavity; a spring 15 is installed in the receiving cavity to support the buffer head 14.

[0033] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
