Description

Technical Field

[0001] This utility model relates to the field of casting process technology, specifically to an automatic shell membrane replacement and sand table exchange system after casting. Background Technology

[0002] In metal smelting and casting, mold casting is a critical process involving pouring molten metal or molten metal solution into a mold for casting. To ensure the quality and stability of the castings, especially for castings requiring prolonged heat preservation, the temperature of the molten metal solution within the mold must be maintained and managed. In this process, the use of an insulated box (or container) is crucial, as it maintains the heat inside the mold during the casting's cooling process, preventing excessively rapid cooling from adversely affecting the casting's quality.

[0003] In traditional production processes, the lid of the insulation box is usually closed manually. Workers need to manually transfer the already poured mold shell onto the insulation box and close the lid. While this method can accomplish the task to some extent, it also has some problems and shortcomings.

[0004] First, manual operation is tedious and labor-intensive. Because the mold shells are typically heavy and complex in shape, manual operation requires a significant amount of manpower, and workers must maintain a high-temperature environment for extended periods, making the working conditions harsh and dangerous. Especially in the high-temperature environment of pouring molten metal, workers face risks of burns and scalds, which can easily lead to accidents. Furthermore, the manual sealing process is susceptible to the skill level and experience of the operators, leading to improper sealing, which can affect the insulation effect and even cause production accidents.

[0005] Secondly, manual box-closing has low work efficiency. In large-scale production, manual operation is not only slow, but also easily affected by factors such as worker fatigue and emotional fluctuations, creating bottlenecks in the production line and affecting the production rhythm. As the modern metallurgical industry continues to increase its requirements for production efficiency and safety, traditional manual operation methods can no longer meet the needs of large-scale, efficient, and intelligent production.

[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an automatic shell membrane replacement sand table system after casting. Utility Model Content

[0007] The purpose of this invention is to provide an automatic shell-locking and sand table exchange system after casting, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A technical solution for an automatic shell-locking sand table exchange system after casting includes:

[0010] The mold shell unloading trolley is set on the unloading track and is used to carry the mold shell after casting;

[0011] An automatic box-locking mechanism includes a box-locking frame, a cylinder, a sliding sleeve, a sliding rod, a lifting plate, a clamping cylinder, and a clamp. The cylinder drives the lifting plate to move vertically through the sliding sleeve and the sliding rod. The clamping cylinder is connected to the clamp and is used to clamp and lock the insulated box to the mold shell.

[0012] The sand table exchange system includes a first sand table exchange track, a second sand table exchange track, a chain drive, and a transfer sand table for carrying full and empty sand tables. The first and second sand table exchange tracks achieve automatic exchange between full and transfer sand tables through the chain drive.

[0013] As a preferred technical solution, a bracket is installed on the side of the unloading track, a guide channel is provided on the top of the bracket, and a guide frame is installed on the mold shell unloading trolley, and the guide frame moves along the guide channel.

[0014] As a preferred technical solution, the first sand table exchange track and the second sand table exchange track are arranged in parallel and are transported synchronously in both directions by a chain drive. The transfer sand table alternately carries a full sand table and an empty sand table between the tracks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention relates to an automatic mold box and sand tray exchange system for cast molds. The system comprises a mold box unloading trolley, an automatic box-closing mechanism, and a sand tray exchange system that work together to automate the post-cast mold box processing. The mold box unloading trolley accurately transports the cast mold boxes to designated locations, while the automatic box-closing mechanism uses a precise mechanical structure to automatically close the insulation boxes, significantly reducing worker workload and improving operational safety and accuracy. Simultaneously, the sand tray exchange system enables rapid and automatic exchange between full and empty sand trays, ensuring continuous and efficient production line operation.
