Description

Rubber-coated solid foam bullet

Technical Field

The utility model relates to a toy bullet, in particular to a rubber-coated solid foam bullet.

Background

The foam bullet launched by the existing soft bullet gun toy mainly comprises a foam bullet body, a hollow solid bullet and a bullet core, the range of the bullet with the structure is limited, and the bullet with the structure has great difficulty in manufacturing an injection mold and injection assembly production, so that the efficiency is very low, the defective rate is high (the defective rate reaches about 30 percent), and the specific expression is as follows;

1) the mold is complex to manufacture:

the hollow solid warhead is just because of the requirement of the assembly appearance of the hollow solid warhead and the solid warhead, so the rear die of the die is made into a large-head die core with a back-off, and a complex, not reasonable but necessary gas cap or push plate structure is added, so the die is complex to manufacture and has higher cost and poor die stability due to various reasons.

2) The injection molding production efficiency is low:

when the hollow solid warhead is produced and injected, the material is soft, and theoretically, the hollow solid warhead can be forcedly ejected, but in fact, the solid warhead is deformed and scrapped (the defective rate is as high as about 20%) because of forcedly ejecting the hollow solid warhead, and the injection production efficiency is low.

3) The assembly is complicated:

the hollow bullet has the safety problem of launching small objects after being broken by abuse test, so that a bullet core is added, and the cost of links such as injection molding, manual assembly and the like is additionally increased;

4) limitation of development trend of product functions:

the existing hollow solid core bullet has a certain hardness (shore hardness is about 45 degrees) due to the injection molding problem, the injection molding difficulty of the softer material is increased, the hardness also limits the range of the bullet to be increased (the maximum range is about 30.3 meters and 100 feet), the increase of the range means the increase of the initial velocity V of the bullet, the bullet impact area cannot be correspondingly increased due to the harder material, and the calculated formula of KED that KED =0.5 mv/m exceeds the safety requirement (requirement is less than 2500J/m) is shown.

It can be seen that in the actual production process of the existing hollow solid warhead, the finished piece is hollow, and the manufacture and demolding of the die are difficult; secondly, the hollow solid warhead and the warcore can only be manually adhered, so that the efficiency is low; the stability of the hollow solid warhead bonded by hand is poor, and the defective rate of products is high; further, an encapsulated solid foam bullet is provided.
