Description

Technical Field

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

[0002] The core shooter is a commonly used sand core molding equipment in the foundry industry. It is also called a sand shooting machine or a core shooting molding machine. Its working principle is to evenly shoot the molding sand into the sand core mold through high-pressure airflow, and form a sand core of the desired shape after compaction and solidification. This equipment has the advantages of simple operation, high production efficiency, and stable sand core quality. Therefore, it is widely used in many industries such as automobiles, motorcycles, diesel engines, air-conditioning compressors, sewing machines, construction machinery, mining machinery, hydropower, ships, casting, machine tools, fire-fighting equipment, etc. The core shooter is usually equipped with a sand shooting mechanism, which is the key to achieve sand core molding. The key part is the sand shooting mechanism, which can accurately control the injection amount and injection speed of the molding sand to ensure the molding quality and accuracy of the sand core. At the same time, the core shooting machine also has other auxiliary mechanisms, such as mold clamping mechanism, core box turning mechanism, etc., to realize an automated and efficient production process. When using the existing core shooting machine, the core box needs to be fixed on the base, and then the sand shooting mechanism is moved to the vicinity of the core box for operation. However, the fixing process of the core box usually cannot be linked with the sand shooting mechanism, which means that the operator needs to manually complete the fixing of the core box. This operation method is not only relatively cumbersome, but also increases The labor intensity of the operator is high, and the position deviation may be caused by human factors during the process of fixing the core box, thus affecting the accuracy and efficiency of sand shooting. Therefore, for the design and optimization of the core shooting machine, it is necessary to consider how to realize the automatic linkage between the core box fixing and the sand shooting mechanism, so as to simplify the operation process, reduce the labor intensity, and improve the accuracy and efficiency of core shooting; for example, "Utility Model CN215786595U A sand shooting mechanism for a core shooting machine can rotate the vertical screw when the motor is started, and the vertical screw can cooperate with the lifting screw sleeve to push the sand shooting barrel and the mounting block on the mounting plate The two sprockets can be rotated synchronously with the cooperation of the chain, so that the rotating shaft and the two horizontal screws connected together can be rotated synchronously. When the horizontal screws rotate, the sliding plate can be pushed to slide on the sliding rod, so that the corresponding positioning plates can be pushed synchronously. Under the action of the two positioning plates, the core box can be fixed, which is convenient and effective. In view of the above problems, there may be technical means to solve them in the prior art, but this case intends to provide an alternative or replacement technical solution. Utility Model Content
