Description
Technical field
The utility model relates to the plastic chair field of injection mold moulding, particularly a kind of seat of injection mold moulding.
Background technology

Summary of the invention
The utility model technical problem to be solved is: the seat of a kind of injection mold moulding of provide simple in structure, the chair back is more comfortable.
The utility model addresses the above problem the technical scheme that is adopted: a kind of seat of injection mold moulding; Comprise chair back plate and seat support; Described chair back plate top is provided with first arcwall face that concaves; Described chair back plate bottom is provided with cambered outwards second cambered surface, described chair back plate and described seat support integral molding.
Compared with prior art, the advantage of the utility model is: the chair back plate top of this injection mold moulding is provided with first arcwall face that matches with human body back that concaves, and the chair back plate bottom is provided with cambered outwards second cambered surface.Like this, the chair back plate of this seat is ergonomic more, and waist is difficult for being pressed against by the chair back plate of plastic chair, is difficult for DOMS.And chair back plate and seat support integral molding, the elasticity of chair back plate is relatively good, and once injection moulding, need not the secondary assembling between chair back plate and the seat support, and is convenient.
As preferably, described seat support is round peviform.Like this, the seat support of this seat is better than the intensity and the resistance to impact of traditional monoplane seat support, and seat support is full of die cavity more easily when injection mo(u)lding, has reduced to shrink unevenly, can prevent that stress from concentrating.
