[0029] In the description of the present application, it should be noted that, unless otherwise specifically specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0030] During the cleaning process after mold sandblasting, the conventional method has the problems of low efficiency and difficult operation; specifically, the sand particles remaining on the surface of the mold need to be effectively separated by manual vibration, but due to the heavy weight of the mold, it is difficult for the operator to easily move or shake the mold; this results in a long cleaning process, high labor intensity, not only reduces production efficiency, but also increases the workload of the operator; in addition, the manual cleaning method cannot guarantee the consistency of the cleaning quality, which may affect the stability of the subsequent production process.
[0031] For example, in a factory producing high-precision glass bottles, mold sandblasting is a key process to improve the surface quality of the bottle body. Each mold weighs about 50 kg, and 100 molds need to be processed every day. When using the traditional manual cleaning method, the cleaning time of each mold is about 10 minutes, and two workers are needed to cooperate; during the cleaning process, the workers need to repeatedly lift, tilt and shake the mold to ensure that the sand particles fall off completely; this not only causes high fatigue of the workers, but also makes it difficult to ensure the consistency of the cleaning effect. Due to the instability of manual operation, about 5% of the molds need to be cleaned repeatedly, further prolonging the entire production cycle.
[0032] Further, if the cleaning problem after mold sandblasting cannot be effectively solved, it will have a chain reaction on the entire production process; first, low cleaning efficiency will directly slow down the production rhythm, affecting overall productivity; second, unstable cleaning quality may cause some sand particles to remain on the surface of the mold; these sand particles may cause surface defects of the bottle body during the subsequent glass bottle forming process, increasing the product failure rate; in addition, long-term high-intensity manual operation may cause occupational health problems, increasing the enterprise's human resource costs and potential risks; therefore, improving the cleaning efficiency and quality after mold sandblasting not only relates to the improvement of production efficiency, but also directly affects product quality and enterprise operating costs; therefore, developing a technical solution that can automatically, efficiently and high-quality complete mold cleaning has an urgent practical need.
[0033] When faced with the problems of low cleaning efficiency and difficult operation after mold sandblasting, several possible solutions are first considered; increasing labor input can improve cleaning speed to some extent, but it cannot solve the problem of high labor intensity, and may instead increase labor costs and the risk of injury; using a high-pressure air gun to blow off sand particles can reduce manual operation, but may cause sand particles to scatter, causing environmental pollution and secondary cleaning problems; an automatic turnover device can automatically turn over the mold, allowing sand particles to fall off under the action of gravity; however, considering the weight and shape of the mold, it is difficult to design a turnover device suitable for various molds, and there may be safety hazards.
