Problems solved by technology

This kind of lifebuoy is easy to leak air due to damage during use, resulting in the inability to continue to use and poor reliability; another kind of lifebuoy is a solid lifebuoy with foam inside and hard plastic outside. Although this kind of lifebuoy solves the problem of inflatable The problem of poor reliability of the life buoy, but because the part in contact with the human body is the outer hard plastic, the comfort is extremely poor, and the hard plastic is easy to cause damage to the human body
When you accidentally bump into hard places (rocks, etc.) during use, the hard plastic is easy to break, exposing the foam material inside, and the foam material is very easy to damage, which will also affect its service life
In addition, the production of this kind of lifebuoy is also relatively complicated, and the cost is relatively high

Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment proposes a manufacturing method of a foam-molded solid buoy. The mold structure adopted is as follows: an upper mold 1 and a lower mold 2 that can be fastened together, and the upper mold 1 and the lower mold 2 are both Annular groove structure; the manufacturing method includes the following steps:

[0032] A: Place the elastic foam material evenly in the lower mold 2, and fasten the upper mold 1 and the lower mold 2;

[0033] B: Heat the upper mold 1 and the lower mold 2, first raise the temperature inside the mold to 170-180°C, so that the elastic foam material in the mold is heated and softened, and keep it for 30-40 minutes; then make the mold The temperature inside is raised to 185°C and maintained for 50-80 seconds;

[0034] C: Loosen the upper mold 1 and the lower mold 2, and lift the upper mold 1, so that the elastic foam material inside the upper mold 1 and the lower mold 2 expands, forming a semi-finished li...

Embodiment 2

[0038] This embodiment proposes a manufacturing method of a foam-molded solid two-color life buoy, which uses the same mold as in Example 1 during its manufacture; the manufacturing method comprises the following steps:

[0039] A: Evenly place the first elastic foam material in the lower mold 2;

[0040] B: Cover a partition 3 on the lower mold 2, and evenly place the second elastic foam material on the partition 3, and then fasten the upper mold 1 and the lower mold 2;

[0041] C: heating the upper mold 1 and the lower mold 2 to increase the temperature in the mold;

[0042] D: Loosen the upper mold 1 and the lower mold 2, and lift the upper mold 1, so that the elastic foam material inside the upper mold 1 and the lower mold 2 expands, forming a semi-finished life buoy;

[0043] E: Trim the semi-finished lifebuoy to get the finished lifebuoy.

[0044] The separator 3 in the step B is an annular plate structure, which is pre-made by the third elastic foam material whose sof...

Embodiment 3

[0048] Different from Example 2, the mold used in this example is as image 3 As shown, the bottom periphery of the upper mold 1 and the top periphery of the lower mold 2 are provided with protruding partition accommodating grooves 5, and the foaming expansion rate of the partition 3 in the B step is lower than that of the first The expansion ratio of the elastic foam material and the second elastic foam material.

[0049] The outer peripheral diameter of dividing plate 3 is identical with the outer circumferential diameter of dividing plate accommodating groove 5, is all greater than the outer circumference of the annular groove of lower mold 2, upper mold 1, even in softening stage like this, the first elastic foaming material, the second elastic The foaming material is mixed with the partition 3, and it will not affect the outer surface of the partition 3, and when the foam expands, because the expansion rate of the partition 3 is lower than that of the first elastic foam m...

Abstract

The invention provides a method for manufacturing a buoy and the buoy manufactured through the method. The method for manufacturing the buoy comprises the following steps that A, elastic foam materials are put in a lower mold uniformly, and an upper mold and the lower mold are closed; B, the upper mold and the lower mold are heated to raise the temperature in the molds; C, the upper mold and the lower mold are loosened, and the upper mold is lifted, so that the elastic foam materials in the upper mold and the lower mold are expanded to be formed into a semi-finished buoy; and D, the semi-finished buoy is trimmed, and the finished buoy is obtained. The solid buoy formed through one-time foaming and manufactured through the method is resistant to acid and alkali, anti-aging, high in elasticity, good in comfort and high in reliability; the method for manufacturing the buoy is simple and ingenious; the foaming quality is improved, the buoy with two colors can be manufactured, and the attractiveness of the buoy is improved.

Description

technical field [0001] The invention relates to a lifesaving device, in particular to a method for manufacturing a lifebuoy and the lifebuoy manufactured by the method. Background technique [0002] There are mainly two types of traditional life buoys. One is the inflatable life buoy, which is usually flat and easy to carry and store. It needs to be inflated when in use. This kind of lifebuoy is easy to leak air due to damage during use, which makes it impossible to continue to use and has poor reliability; another kind of lifebuoy is a solid lifebuoy with foam inside and hard plastic outside. Although this kind of lifebuoy solves the problem of inflatable The problem of poor reliability of the lifebuoy, but because the part in contact with the human body is the hard plastic of the outer layer, the comfort is extremely poor, and the hard plastic is also easy to cause damage to the human body. When you accidentally bump into hard places (rocks, etc.) during use, the hard pla...
