A production process for making side-type sign plate barbells by filling

Abstract

The invention discloses a production process for a barbell disc with a side logo manufactured in a filling mode. The production process is used for achieving display of the logo on the outer side surface of the barbell disc. The production process comprises the following steps that a, a second mould is filled with a first raw material; b, the second mould is embedded into a first mould; c, the first mould and the second mould are filled with a second raw material; and d, the first mould and the second mould are taken out. According to the production process for the barbell disc with the side logo manufactured in the filling mode, the barbell disc side logo part and a main body part are formed through the detachable moulds correspondingly, the mould for the main body part can be repeatedly used, resources are saved, the cost is lowered, and the product main body part and the logo part can be well bonded; and the production process is simple, operation is convenient, the side logo and the barbell disc main body form an integral structure, the logo is not prone to falling off, and the yield of production is increased.

Description

technical field [0001] The invention relates to a production process of sports equipment, in particular to a production process of a barbell piece. Background technique [0002] As a popular sports and fitness equipment, the barbell has a wide range of applications. There are many brands of barbells on the market. Manufacturers usually form a distinction by marking the LOGO on the barbell plate of the barbell. In the prior art, the main methods of fixing the product LOGO on the barbell sheet include surface printing and sticking labels. However, after long-term use, the product LOGO is easy to fall off the barbell sheet, which affects the appearance and recognition of the product. In addition, the position of the LOGO of the existing barbells on the market is generally located on the upper surface or the lower surface of the barbell plate cylinder, and the LOGO is marked on the outer surface of the side surface of the barbell plate and is rarely used due to high requirements...

Problems solved by technology

In the prior art, the main ways to fix the product LOGO on the barbell are surface printing and sticking labels. However, after long-term use, the product LOGO is easy to fall off from the barbell, which affects the appearance and recognition of the product.

In addition, the LOGO position of the existing barbells on the market is generally located on the upper or lower surface of the barbell cylinder, and the LOGO is rarely used on the outer surface of the side of the barbell due to the high requirements on the production process.

[0003] Due to the limitation of the production process, the three-dimensional LOGO part and the main part of the barbell plate are integrated into the molding process through the mold. Since the raw material of the product is liquid and the side of the product is curved, the ordinary method of filling raw materials is used on the barbell plate. If the LOGO is added on the outer surface of the circumference, the liquid material will flow out due to the effect of gravity; if it is filled with solid material, the combination of the LOGO and the main part of the product is not good and it is easy to separate
