Problems solved by technology

[0004] The conventional physical method is to fill one cavity of the flank with the molding material of the flank foam; the main surface of the core is to fill another cavity with another molding material, but the actual operation often causes the materials in the two cavities to mix together If the situation occurs, the uneven hardness of the foam will affect the ride comfort perception of the driver and passengers

Embodiment 1

[0059] like Figure 1-5 As shown, a multi-hardness one-time molding automobile seat foam mold includes a male mold 1 and a female mold 2, wherein the female mold 2 and its carrier are arranged in conformity with the shape, and the seat part made by the male mold 1 in the foam mold can be directly Assembled with the cover (mask) in the mode of buckle or Velcro, the carrier of the seat part produced by the female mold 2 in the foam mold is a skeleton steel wire (curtain) or a skeleton steel plate or a skeleton plastic plate. The structure of the female mold 2 involved in the present invention can be freely designed. Generally, it can follow the shape of its supporting body, and can also be used as a design structure for weight reduction.

[0060] Described male mold 1 comprises male mold body, and the male mold body is provided with a plurality of microelements of the same type, and the microelements of the same type are sequentially arranged on the male mold body from top to bo...

Embodiment 2

[0109] The main body of the male mold 1 is provided with micro-units in various forms to realize the macroscopic control of the foaming hardness of a cavity of an isocyanate polyester polyether filler. The micro-units involved refer to the multiple arc-shaped protrusions 11 or grooves 12 provided on the male mold 1 from top to bottom, and the area and depth of different arc-shaped protrusions 11 or grooves 12 are arranged by design Realize multi-hardness zonal foam. During the foam molding process, only one isocyanate polyester polyether filler enters the cavity of the male mold 1 from the filling port of the male mold 1, avoiding the dual-hardness conventional chemical foaming molding method to obtain uneven hardness of the foam body. Debugging difficult puzzles with controlled hardness. The foam body obtained through the mold forms a surface contact between every two arc-shaped protrusions or grooves and the protective surface to support the protective surface.

Embodiment 3

[0118] Take the semicircular groove 12 designed on the male mold 1 as the microelement as an example, the diameter of the microelement in the upper part of the back is 40mm, the depth is 30mm, the diameter of the microelement in the lower part of the back is 40mm, the depth is 20mm, and the attitude maintaining area is not large when turning. Involving the tactile area, the tactile area of ​​the lumbar spine (part) has a diameter of 30 mm and a depth of 10 mm, the diameter of the micro-element of the hip bone and sacrum tactile area is 20 mm, and the depth of 20 mm, and the diameter of the micro-element of the hip bone and coccyx tactile area of ​​the seat cushion of the car seat is 10 mm , the depth is 10mm, the microelement diameter of the thigh tactile area is 20mm, the depth is 15mm, the microelement diameter of the calf tactile area is 40mm, and the depth is 20mm;

[0119] The present invention improves the method of controlling hardness by interfering with foam micropores...

Abstract

The invention belongs to the technical field of automobile seat foam forming, and particularly relates to a multi-hardness automobile seat foam one-time forming mold and method. The mold comprises a male mold and a female mold, the male mold comprises a male mold body, a plurality of infinitesimal elements of the same kind are arranged on the male mold body, and the infinitesimal elements of the same kind are sequentially arranged on the male mold body from top to bottom; the infinitesimal elements are divided into bulges and grooves, and the bulges and the grooves are semicircular, 1 / 4 circular or irregular arc-shaped; and the shape of the male mold for foam forming is controlled through the infinitesimal design on the male mold, then foaming forming of multi-hardness foam is achieved, foam with multiple macrohardness subareas can be obtained through forming only through one kind of filler, and the foam hardness needed by different subareas is easy to control.

Description

technical field [0001] The invention belongs to the technical field of automobile seat foam molding, and in particular relates to a multi-hardness one-time molding automobile seat foam mold and method. Background technique [0002] At present, vehicle seats are mainly composed of skeleton, foam and face protection (mask). Based on the existing foam molding process, in order to meet the user's needs for seat comfort to the greatest extent, most seats use dual-hardness Foam is the two foam hardnesses of the side wings and the main surface (core surface), which are far from satisfying the urgent needs of drivers and passengers for improving seat comfort. From the point of view of the comfort of human body perception engineering, the softness perceived by the driver and passengers at the beginning of seating is different from the hardness required for support after seating. At present, seat manufacturers use a layer of 10-20mm softer foam to meet the needs of drivers and passeng...
