Embodiment Construction

[0014] As shown in the figure: taking the production of a standard basketball as an example, the present invention is composed of two hemispherical molds 1, and the surface of the mold is evenly distributed with vacuum pumping holes 3, which are respectively connected with the vacuum pump, and the surface of the mold is also provided with inner tube inflation holes 4. The inner wall of the mold is provided with a ball piece and a ball stem groove 2; the main body of the mold is made of aluminum or steel;

[0015] Its manufacturing process includes the following steps:

[0016] 1) Firstly, add a winding layer to the bladder after winding, then cover the winding layer with a rubber layer of 0.8-1.2cm, and put the liner wrapped and covered with the rubber layer into the inner tank of the corresponding standard size. In the bladder mold, inflate 0.8-1.0Mpa, and at the same time maintain the mold temperature at 140-150°C, 5-10 minutes, release the mold to become an inner tube, and ...

Abstract

A technology for making basket balls by mechanical sticking includes winding thread on an internal ball to form a wound thread layer, sticking rubber layer, sulfurizing, coating adhesive, arranging prefabricated 8 surficial pieces and the spacing strips in a dedicated mould, heating the mould while vacuumizing it for attaching them on the inner surface of said mould, putting said internal ball in mould, closing mould, and inflating the internal ball while heating the mould.

Description

technical field [0001] The invention belongs to a production process and special equipment for competition and sports equipment, in particular to a production process and a special mold for a machine-bonded basketball. Background technique [0002] Basketball is a kind of competition, sports equipment commonly used, and basketball is an important sports. Existing basketballs are made by bonding leather and corresponding inner tubes. Since the bonding is manual, there are problems such as high labor intensity, low production efficiency, serious pollution, and unstable quality. Contents of the invention [0003] The purpose of the present invention is to solve the above problems in the traditional hand-pasted basketball, and to provide a machine-bonded basketball production process and a special mold. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A manufacturing process of a machine-bonded basketball. Firs...
