Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting body.
[0002]
[Prior art]
Conventionally, a mounting body on which an object is placed is a combination of a plate-like member formed of a synthetic resin on a top plate, a bottom plate, a side plate, a back plate, etc., and these are combined in a frame shape. At least one of the plate, bottom plate, side plate, etc. is required to have strength against the load from the point on which the object is placed, and those that are installed indoors have a beautiful appearance, especially the surface exposed to the outside. It is required to be.
[0003]
For example, in the case of a mounting body on which a television receiver is mounted, the right and left side plates are required to have strength against loads from the viewpoint of holding a considerable weight of the television receiver, and the top plate surface is mounted. Since it is covered by the television receiver and the back surface of the bottom plate is in contact with the installation surface, a beautiful appearance is required on the surfaces of the left and right side plates.
[0004]
FIG. 4 is a plan sectional view of the main part of a side plate constituting a conventional mounting body. A side plate 101 formed by injection molding of plastic is formed by integrally molding an outer member 102, an inner member 103, and a reinforcing rib 104. The outer member 102 and the inner member 103 have a hollow structure formed integrally with the reinforcing rib 104.
[0005]
[Problems to be solved by the invention]
By the way, in the side plate 101 shown in FIG. 4, sink marks and flow marks are likely to be generated on the surface of the side plate 101 during molding. In order to maintain the quality, it is necessary to coat the surface to cover the sink marks and the flow marks, and there is a problem that the mass productivity is poor and the cost is high.
[0006]
Sink is a phenomenon in which when a resin that has been heated and melted is cooled and cured, a portion having a large thickness contracts and a recess is formed on the surface due to a delay in cooling and hardening compared to a portion having a small thickness. Accordingly, in the outer member 102 and the inner member 103, the portion A where the reinforcing rib 104 is present is thick, and therefore, a concave sink is likely to occur in this portion A as shown in FIG. .
[0007]
The flow mark is a phenomenon in which when a turbulent flow occurs in the plastic flow flowing into the cavity, the turbulent plastic flow remains as a trace on the surface of the molded body. Therefore, when the reinforcing rib 104 is present, turbulent flow is generated in the plastic flow, and flow marks are likely to be generated on the surfaces of the outer member 102 and the inner member 103 after molding.
[0008]
The present invention solves the above-mentioned problems, and provides a mounting body composed of structural members that satisfy both strength and appearance.
