Embodiment 1

[0024] This embodiment relates to an aluminum mold for a polyurethane foam product with a built-in airbag, which is used to manufacture the backrest of a vehicle seat. figure 1 , figure 2 As shown, the mold includes an upper mold 1 and a lower mold 2. Inside the aluminum mold, there is a mold cavity 3 formed by the fastening of the upper mold 1 and the lower mold 2. The wheel mouth of the mold cavity 3 and the outer surface of the backrest of the vehicle seat Shape accordingly. On the lower mold 2, six iron sheets 6 are embedded, and a circular magnetic sheet 7 is adsorbed on each iron sheet 6. The inner surface of the lower mold 2 at the bottom of the mold cavity 3 is provided with a plurality of airbag units at intervals. Each airbag unit is composed of a plurality of backguy wires 4 and airbags 5 corresponding to the number of backguy wires 4. One end of the backguy wire 4 is attached to the iron sheet. The periphery of the magnetic sheet 7 on 6 is fixedly connected, and...

Embodiment 2

[0028] This embodiment relates to a method of using the aluminum mold structure in Embodiment 1 to manufacture polyurethane foam products with built-in airbags, the method comprising:

[0029] Step 1, clean the mold cavity 3 of the aluminum mold, and spray a layer of release agent; wherein the release agent is a solvent-based combination wax; connect multiple airbags arranged at intervals on the inner surface of the lower mold 2 at the bottom of the mold cavity 3 unit.

[0030] Step 2, inject the raw materials of the mixed polyurethane foam product into the mold cavity (3) of the mold for foaming reaction; the raw materials of the mixed polyurethane foam product in this embodiment adopt the common raw materials and Components, such as isocyanate (commonly known as: black material) and combined polyether (mainly composed of polyether polyols, amine catalysts, silicone oil, crosslinking agent, distilled water, etc., commonly known as: white material) according to white / black = 1...

Abstract

The invention relates to an aluminum mold for airbag-embedded polyurethane foaming products, which comprises an upper mold (1) and a lower mold (2), a mold cavity (3) formed by buckling the upper mold (1) and the lower mold (2) together is arranged in the aluminum mold, the inside surface of the lower mold (2) at the bottom of the mold cavity (3) is provided with a plurality of airbag units which are arranged at a certain interval, each airbag unit is composed of a plurality of drawing wires (4) and airbags (5) of which the number is corresponding to that of the drawing wires (4), one ends of the drawing wires (4) are fixedly connected with the lower mold (2), and the other ends of the drawing wires (4) are fixedly connected with the airbags (5) in a free state in the mold cavity (3). Meanwhile, the invention also provides a preparation method for preparing products by using the mold and products prepared by using the method. By using the technical scheme of the invention, an airbag-embedded polyurethane foaming product used by vehicle seats has a better damping effect.

Description

technical field [0001] The present invention relates to a foamed product used in vehicle seats, in particular to a polyurethane foamed product with a built-in airbag. At the same time, the present invention also provides a preparation method of the polyurethane foamed product with a built-in airbag and the method used in the production process. aluminum mold. Background technique [0002] Due to the many advantages of polyurethane foam products, its application range is wide. For example, in the use of vehicle seats, the rebound ability of polyurethane foam products under the better support effect is used to realize the support for passengers. Since the human body's perception of external vibration is mainly affected by the vibration intensity and transmission speed, when the vibration of the vehicle is transmitted to the human body through the seat, the seat made of polyurethane foam products cannot play a good vibration effect. Contents of the invention [0003] In orde...
