Description

technical field

[0001] The invention relates to a BB shot forming device, in particular to a BB shot forming device capable of collecting surplus material and ensuring the integrity of the BB shot after compression molding. Background technique

[0002] Air guns are often used as ammunition catapults for war simulation training or games. Compared with gunpowder-fired guns that are generally dangerous and lethal, air guns use compressed air as the propulsion power to drive the ammunition to be ejected. Reduce the damage to the target or human body. The ammunition used in air guns is also different from the metal bullets filled with gunpowder. Instead, it uses plastic or powder compression molded projectiles (commonly known as BB bullets).

[0003] Traditionally, BB bullets are manufactured by means of reverse molding, such as Figure 1-1 to Figure 1-4 As shown, the powder material 20 to be used to make the BB bomb is placed into the forming mold. The molding die mainly incl...
