Description

Technical Field

[0001] The utility model relates to the technical field of core shooting machines, in particular to a core shooting machine with a waste sand collecting device. Background Art

[0002] In the field of modern precision casting, core shooting machines, as the core equipment for producing high-quality sand cores, play an indispensable role. It efficiently and accurately injects carefully proportioned dry sand or mixed sand into the core box to ensure that the manufactured sand core has extremely high dimensional accuracy and surface finish, which directly affects the quality of the final casting. With the continuous pursuit of production efficiency and the increasing standards of the working environment in the manufacturing industry, a prominent challenge faced by core shooting machines in practical applications is the degradation of the working environment caused by poor waste sand management.

[0003] In the operation process of traditional core shooting machines, a large amount of waste sand that is not effectively utilized is scattered around the working area while the sand core is being formed. These scattered waste sands not only seriously affect the cleanliness of the workshop and reduce the overall hygiene level of the working environment, but also pose a potential threat to the health of operators. Long-term exposure to dusty environments may lead to occupational health problems such as respiratory diseases. In addition, the random distribution of waste sand increases the difficulty of daily cleaning work, consumes a lot of manpower and time costs, and at the same time, the scattered waste sand may also invade the interior of the equipment, increase the maintenance frequency, and affect the stable operation and life of the equipment.

[0004] Existing waste sand treatment methods, such as using an air blowing device to temporarily blow waste sand away from the work area, can improve the local environment in the short term, but this method fails to fundamentally solve the problem of waste sand collection and reuse. Air blowing treatment can easily cause secondary diffusion of waste sand, forming a new source of pollution, and is not conducive to the recovery and recycling of waste sand resources, which is contrary to the current green manufacturing and sustainable development concepts advocated.

[0005] In view of the above challenges, an innovative waste sand collection solution is urgently needed to overcome the limitations of the existing technology. This application proposes a core shooting machine design with a waste sand collection device, which aims to effectively guide and centrally process the waste sand generated during the operation by integrating an efficient waste sand collection system, fundamentally improve the working environment, and increase the recycling rate of resources, while meeting the comprehensive requirements of the modern foundry industry for high efficiency, environmental protection, and safe production.
