Embodiment 1

[0033] A soft ball demoulding process, comprising the steps of:

[0034] (1) Inject liquid silicone into the mold, specifically, into the sphere cavity of the mold. Before injection, the mold needs to be preheated in advance, and the preheating temperature is 110°C;

[0035] Such as figure 1 As shown, the mold includes a mold core with a spherical cavity, and the mold core includes a mold core A, a mold core B, a mold core C and a mold core D, and the mold core A and the mold core B cover the mold core C and the mold core Outside the mold core D, a spherical cavity is formed between the mold core A and the mold core B, the mold core C and the mold core D, wherein the mold core C and the mold core D are spherical after the mold is closed, and the lower end of the mold core C is provided with Convex, there is a depression inside the mold core D that matches the protrusion of the mold core C, the inner diameter of the mold core A and the mold core B is hemispherical, and there i...

Embodiment 2

[0044] A soft ball demoulding process, comprising the steps of:

[0045] (1) Inject silica gel into the mold, preheat the mold in advance, and the preheating temperature is 100°C. ;

[0046] (2) After the silica gel is cured to form a silica gel ball, the mold core A and mold core B are moved to both sides relative to mold core C and mold core D respectively;

[0047] (3) Keep the mold core D still, the mold core C moves upward relative to the mold core D, and an air passage is formed between the mold core C and the mold core D;

[0048] (4) The manipulator above the mold core C drives the jig to move down until the jig covers the mold core C, the mold core D and the cured silicone ball;

[0049] (5) Blow compressed air to the cured silicone ball through the air inlet between core C and core D, set the air inlet at the middle part where core C and core D join, and enter the air inlet The air passes through the ventilation channel between the mold core C and the mold core D ...

Embodiment 3

[0052] A soft ball demoulding process, comprising the steps of:

[0053] (1) Inject silica gel into the mold, preheat the mold in advance, and the preheating temperature is 100°C. ;

[0054] (2) After the silica gel is cured to form a silica gel ball, the mold core A and mold core B are moved to both sides relative to mold core C and mold core D respectively;

[0055] (3) Keep the mold core D still, the mold core C moves upward relative to the mold core D, and an air passage is formed between the mold core C and the mold core D;

[0056] (4) The manipulator above the mold core C drives the jig to move down until the jig covers the mold core C, the mold core D and the cured silicone ball;

[0057] (5) Blow compressed air to the cured silicone ball through the air inlet between core C and core D. The air passes through the ventilation channel between the core C and the core D to expand the cured silicone ball until it fits the inner ring of the jig; blowing compressed air ado...

Abstract

The invention discloses a flexible ball demolding process. The flexible ball demolding process comprises the following steps that a silica gel sphere is injected into a mold; the silica gel sphere isformed after a silica gel is cured, and a mold core A and a mold core B are moved towards two sides to be opened; a mold core C moves upwards relative to a mold core D, a manipulator above the mold core C drives a jig to move downwards, until the jig is sleeved with the mold core C and the mold core D and the solidified silica gel sphere; the solidified silica gel sphere is blown by an air inlet between the mold core C and the mold core D, so that the solidified silica gel sphere is expanded, and an inner ring of the jig is attached until an inner ring of the jig is attached; and the manipulator drives the jig to pull the silica gel sphere upwards, so that the silica gel sphere is separated from the mold. According to the demolding process, the flexible ball has a relatively small demolding hole, so that the integrity of the flexible ball in the small demolding hole is effectively ensured, and the structure of the whole sphere is not damaged.

Description

technical field [0001] The invention relates to the technical field of sports equipment processing, and mainly relates to a soft ball demoulding process. Background technique [0002] Softball is a sport that is suitable for both middle-aged and old people, teenagers, and young adults. It is a special racket held by the athlete. The racket is composed of a handle and a racket frame. The rubber soft surface with air holes, which acts as a buffer, throws the ball back and forth in an arc-shaped way. It can be thrown by two people, practiced alone, passed by several people or competed across the net to achieve fitness, entertainment, performance and competition. [0003] The spheres of existing soft balls are mostly made of PVC material, which is directly formed by thermoplastic. The surface of the ball is uneven, and the force will be uneven when the soft ball is in motion. mm, and the existing soft ball has an inflatable pinhole about 2-3 cm long at the demoulding hole, bec...
