BB pill forming device

Abstract

The invention relates to a BB pill forming device comprising a top die part, a bottom die part and a middle die part. The opposite ends of the top die part and the bottom die part are respectively provided with a first forming tank and a second forming tank, the opposite faces of the first forming tank and the second forming tank respectively form a first cambered surface and a second cambered surface, a first pushing member and a second pushing member making pushing motions are respectively arranged in the first cambered surface and the second cambered surface, the top die part and the bottom die part are oppositely displaced, and a pressed forming path is limited between the top die part and the bottom die part. The middle die part is provided with a pressing channel for inserting the top die part and the bottom die part on the pressed forming path, at least one feeding opening is arranged in the pressing channel, and a feeding pipe communicated with the feeding opening is arranged in the middle die part.

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...

Problems solved by technology

Although the surface of the projectile 21 can be smoothed after grinding, but due to the poor roundness, it will cause jamming or affect the accuracy of the shot when shooting

And after a long time of surface treatment, it will inevitably lead to an increase in manufacturing costs and an increase in time, which is not in line with economic benefits.

What's more, under the strong compression molding force, it is easy to damage the structure of the upper mold 11 or the lower mold 12, thereby reducing the service life of the forming mold and increasing the production cost
