[0001] The invention relates to the technical field of mold casting and molding, and in particular to a core insertion auxiliary device and a core insertion method. Background Art

[0002] The structure of some products is usually achieved by making molds. Some products are hollow structures. Generally, they are poured after the inner core is built in. After the pouring and curing, the inner core is demoulded to form the required structure. However, there are also some products with small pouring inlet space, and the material cannot be poured in smoothly after the inner core is built in. Even after pouring, the filling quality cannot be guaranteed.

[0025] S4: Remove the plugging and fixing nut at the lower end of the guide rod 6, and place the counterweight 11, so that the inner core 1 slowly descends. When the descending speed slows down, the number of counterweights can be increased;

[0026] S5: After the inner core reaches the specified position, remove the counterweight block, remove the counterweight block pull rod by pulling out the pin, clean the slurry on the outer surface of the guide rod and the connection between the guide rod and the inner core, unscrew the guide rod, install the fixing nut of the inner core, fix the inner core, realize the positioning of the inner core, unscrew the pressure ring, remove the guide cylinder, remove the pressure rod, and complete the whole process of core insertion.

[0027] Furthermore, the non-threaded portion of the S3 inner core 1 is completely butted against the guide rod 6 and has the same diameter, ensuring a smooth joint.

[0028] Furthermore, the S4 counterweight block plays the role of pulling down the inner core by stacking different numbers or designing with different weights, and the pulling-down speed is adjusted by different weights.
