Problems solved by technology

However, hard fabrics such as PVC or genuine leather are not easy to deform under tension, and the fabrics on both sides of the opening 2 of the mask are difficult to fit, which reduces the resistance of raw materials overflowing from the small holes. The overflow speed of the material will increase, so when the chemical material solidifies, the overflow area around the small hole will becom

Embodiment Construction

[0023] The characteristics and advantages of the method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] In order to solve the contradiction between the height of the air outlet point and the overflow of raw materials, the present invention provides a new PIP foam molding method for automobile seat headrests, which can greatly increase the resistance of the air outlet point of the cover to the overflow of chemical materials, and maximize the Shorten the distance between the air outlet point and the opening 2 of the mask. While better reducing the triangular area where the gas cannot be discharged, the possibility of raw materials seeping out from the gas outlet point is avoided.

[0025] According to one aspect of the present invention, when the face cover opening 2 of the headrest is at the highest point of the headrest product, or by adjusting the angle of the product, the opening 2 ca...

Abstract

The invention provides a molding method for manufacturing a headrest of a vehicle by applying an improved pour in place method. The headrest comprises a preassembled trim cover and a framework, wherein the trim cover is formed by compounding a fabric surface, a PU layer and a TPU film layer; the preassembled trim cover and the framework are placed in a die; a foaming raw material is poured through an opening of the trim cover which penetrates the framework; and the die is closed to manufacture a final product through a curing process, wherein the highest point of the headrest is selected as an exhaust position which is provided with a plurality of fine, narrow and long linear notches. The fabric surface is made of a permeable material, when the opening of the trim cover is not the highest point of the product, an invisible position on a flange of the trim cover is selected as the exhaust position; and the exhaust position is provided with a plurality of impermeable holes.

Description

technical field [0001] The invention relates to a molding method of a headrest of an automobile seat, in particular to a molding method for manufacturing the headrest of an automobile seat by using an improved mold-opening internal foaming (Pour in Place) method. Background technique [0002] The headrest of a car seat is an indispensable and important part of the car. In addition to meeting the safety function, people have higher and higher requirements for the appearance quality, and the design shape is also more and more diversified. The original coating process can no longer meet people's needs. The PIP (Pour in place) process can meet the appearance quality requirements of complex shaped products. [0003] PIP stands for in vivo foaming. The PIP process is divided into two processes: closed mold casting and open mold casting. In the processing and molding of mold opening PIP, such as figure 1 As shown, the skeleton 6 is penetrated into the mask 5 through the opening...
