Abstract

A one-step molding seamless solid ball comprises an inner core (1) and an outer shell (2). The inner core (1) is a one-step molding solid ball body by pouring in a mold. The outer shell (2) is a one-step molding integral structure enveloping the inner core (1). The materials of the inner core (1) and the outer shell (2) comprise polyether glycol and isocyanate polymer. The one-step molding seamless solid ball can be easily and quickly manufactured, does not require suture line and has long service life.

Description

a seamless one-piece solid ball

Technical field

The invention relates to a ball, in particular to a one-time forming, seamless solid ball, including a solid ball, a net, a golf ball or other ball, belonging to the technical field of sporting goods.

Background technique

The basic components of the ordinary solid ball are the bladder, the ball skin and the suture. In the process of production, usually after the bladder is produced, the ball is matched according to the size of the bladder. This is inefficient, and many leather materials may cause a short service life if they are not well stitched, and if the skin is relatively hard, it is difficult to suture, purely manual operation, extremely low efficiency, and high return rate.

Summary of the invention

The invention is directed to the defects that the processing in the ball production is complicated and the life of the ball is short, and the solid ball which is formed by the mold once is provided, the skin of the ball has no gap, no suture is needed, and the service life is long.

Specifically, the present invention is a seamless one-piece solid ball characterized in that the solid ball comprises two parts, a inner liner and a outer skin, wherein the inner tank is a solid sphere formed by one-time casting of the mold. The outer skin is a one-piece molded overall structure covering the inner liner.

The seamless ball-shaped solid ball is characterized in that the inner liner and the outer skin are synthesized from a polyether polyol and an isocyanate prepolymer, but the material is not limited to a polyether polyol and an isocyanate prepolymer. In fact, any molded or elastic rubber or synthetic plastic can be used as the material.

The utility model relates to a solid ball which is seamlessly formed at one time, characterized in that the outer skin surface is further provided with a curved rib formed by casting. The ribs mimic the shape of the suture, but are not sutures, but are cast once by a mold.

The seamless ball forming solid ball described in the present invention has the following advantages:

1. The inner liner and the outer skin are molded by one-time casting, and the manufacturing process is simple and fast;

2, the outer skin is a whole, no suture is needed, so it is not easy to be broken and has a long service life;

3. The inner liner and outer skin are synthesized by using polyether polyol and isocyanate prepolymer. The elasticity and strength are excellent, which reduces the dependence on leather and contributes to energy saving and environmental protection.

Among them, 1 is the inner liner, 2 is the outer skin, and 21 is the rib.

detailed description

The following describes a seamlessly formed solid ball according to the present invention with reference to the accompanying drawings, in order to better understand the technical content of the present invention, and not to limit the technical content. In fact, Within the spirit of the invention, the improvement of the structure of the solid ball, the addition, subtraction and replacement of the corresponding parts have been within the technical solution claimed by the present invention.

A seamlessly formed solid ball according to the present invention comprises two parts, a liner 1 and a sheath 2, wherein, as shown in FIG. 1, the liner 1 is a solid sphere formed by one-time casting of a mold, and the outer skin 2 is also The embossed rib 21 having a pattern can be formed on the surface of the outer skin 2 by the single casting of the mold, and the shape and pattern of the rib 21 can be arbitrarily designed, and the rib is also made of a mold. Once formed.

In the production, the liner 1 is first casted, then the liner 1 is placed in the mold, and then cast, to obtain the outer skin 2 attached to the surface of the inner liner 1, and the materials of the inner liner 1 and the outer skin 2 include polyether. Polyol and isocyanate prepolymer, or other materials, and finally get a seamless solid ball in one time.

The solid ball which is seamlessly formed in the invention has the advantages of quick and easy processing, no need for suture, long service life and broad application prospect.

Claims

The utility model relates to a solid ball which is seamlessly formed at one time, characterized in that: the solid ball comprises two parts of a liner and a skin, wherein the inner tank is a solid sphere formed by one casting of the mold, and the outer skin is once covered by the inner liner. The overall structure of the forming.
A seamlessly formed solid ball according to claim 1, wherein the material of the inner liner and the outer skin comprises a polyether polyol and an isocyanate prepolymer.
