Description

Technical Field

[0001] The utility model relates to the field of core shooting machines, in particular to a core shooting machine which is convenient for core connection. Background Art

[0002] The core shooting machine is equipment for the foundry industry. At present, there are still some problems in the use of the core shooting machines on the market. For example, after casting, the lifting mechanism on the lower die seat of the traditional core shooting machine will eject the casting from the lower die seat. It lacks an automatic unloading structure and requires staff to take it out. However, the casting after heating and forming is easy to scald the staff due to the high temperature. At the same time, when using the traditional core shooting machine, it is easy for the sand shell to be hollow or not solid. The fundamental reason is that the coated sand is easily affected by moisture and agglomerates, which leads to blockage during unloading. The traditional practice is to clean up all the remaining sand inside the sand hopper, which is not only troublesome, but also reduces the working efficiency of the core shooting machine and wastes time.
