Embodiment 1

[0023] A kind of molding process of natural latex foam product provided by the invention, it comprises the steps:

[0024] 1) heating the coating (1) to soften it;

[0025] 2) The softened coating (1) is pre-shaped by the upper convex mold (A1) and the lower concave mold (B), and the molded coating (1) fits in the lower concave mold (B) without Move again, such as figure 1 , figure 2 Shown, in this process, control the temperature of mold up and down, to guarantee not to cause the coking of the soft natural latex foam foam (2) poured in the mould;

[0026] 3) Change the upper concave mold (A2) so that it is combined with the lower concave mold (B), and then pour soft natural latex foam (2) into the space between the upper concave mold (A2) and the lower concave mold (B). In the cavity, it can be extruded. like image 3 , Figure 4 shown.

[0027] The heating temperature of the coating (1) in the above-mentioned step 1) is not to make the coating coking, but it is advis...

Embodiment 2

[0029] The molding process of the present invention is identical with embodiment 1. The difference is that if the complexity of the product is high, it needs to be combined and extruded as a whole, such as Figure 5 As shown, finished products such as Figure 6 shown.

Embodiment 3

[0031] The present invention provides another molding technique of natural latex foamed product, it is characterized in that comprising the steps:

[0032] 1) Apply soft natural latex foam (2) on the covering (1), such as Figure 7 shown;

[0033] 2) Heating the soft natural latex foam (2), making it extruded in the cavity of the upper convex mold (A1) and the lower concave mold (B), and controlling the heating temperature to ensure the soft natural latex foam The foam (2) is dried until it is extruded by the mold without breaking and is not overheated so that it cannot be pressurized, such as Figure 8 shown.

[0034] The heating temperature of the natural latex foam (2) in the above step 2) is the best processing time when the latex foam is dried to 70%.

Abstract

A process for shaping foamed natural latex product includes such steps as heating the covering material to soften it, shaping it with the upper male die and lower female die, leaving it in lower female die, exchanging the upper male die with female die, pouring foamed natural latex into die cavity, and pressing.

Description

1. Technical field: [0001] The invention relates to a molding process of a natural latex foam product, which belongs to the innovative technology of the molding process of a natural latex foam product. 2. Background technology: [0002] Foamed products have been widely used in all walks of life, but for non-thermoplastic natural latex foamed colloids, due to their physical properties, there are many restrictions when processing coverings. If it is damaged, or it can only be simply coated or flatly embossed, embossed, etc. during the production process, the original many usable characteristics of the non-thermoplastic latex colloid (breathable, compression-resistant, elastic, environmentally friendly, etc.) With the pressure of the market economy that technology cannot break through, it loses competitiveness. For example: the natural latex foaming colloid is an open cell structure, so it can get the best ventilation effect, but because this type of molding is covered with a ...
