Abstract

PURPOSE:To prepare the titled molded article for a bureau in semiforeign style etc. having an arc shape, a slender semi-elliptical shape or a rectangular shape, etc., provided with concave or convex pulls, easy to set, excellent in appearance, low in cost and capable of a large variety and small-scale production. CONSTITUTION:A plate, a plane plate of synthetic resin or expanded synthetic resin is pressed between the male and the female mold 2, to take an example, for a pull in a convex shape to obtain the desired decorative plate molded article in an arc shape, a slender semi-elliptical shape or a rectangular shape, etc. and having pulls in a convex shape 1 continuing to the plane sections.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to the use of synthetic resin or low-foaming synthetic resin that has recessed or bulging handles on furniture such as Japanese-style chests of drawers or wardrobes, or on doors or drawers of kitchen furniture such as cupboards. This invention relates to resin decorative laminates or decorative shaped articles, and their manufacturing method by thermoforming.

Conventionally, decorative plywood made of thermosetting resin is used on wooden or lauan surfaces for decorative boards such as chests of drawers and cupboards.
These handles are made of injection-molded synthetic resin or metal presses, castings, etc., and are screwed or fitted, that is, used as bulge or recessed handles.

All of these handles require a lot of money and time for the molds required to manufacture them, and as mentioned above, it takes time and is expensive to attach the handles. There were drawbacks.

The present inventor has arrived at this invention as a result of intensive research to eliminate these drawbacks.

According to this method, a decorative board with a handle already thermoformed is used on the front, so all you have to do is glue this decorative board.
The handle will also be attached at the same time. However, in terms of design, it is an extruded product with a wide width, and the shape is semicircular, semicircular, rectangular, etc., and the angle of inclination and size of the rise from a flat surface are similar to that of a wooden mold. By changing the design of only the mold (a simple male mold is sufficient), it is now possible to economically produce products that meet market needs. be.

That is, the present invention provides: (1) A synthetic resin product having a shape such as an arc shape, a circular shape, etc., and provided with a bulge-type or recess-type handle connected to a flat plate or an irregularly shaped product having a flat plate surface; Molded product made of foamed synthetic resin decorative board.

(2) A flat plate made of synthetic resin or foamed synthetic resin or a different shaped product having a flat plate surface is heated to form a male or female shape of a bulge-type or concave-type handle in the shape of an arc, a circle, etc. A method for manufacturing a synthetic resin decorative board molded product having a flat plate or a flat plate-shaped irregularly shaped product and a concave or concave handle connected to the flat plate or flat plate-like shaped product is characterized by being sandwiched between molds and press-molded.

The molded product, which is a flat plate made of synthetic resin or foamed synthetic resin before the handle is molded, or a flat plate of an irregular shape such as having an angled hook-shaped portion, is most preferably an extrusion molded product. This is because it can be cut to any length, and the handle can be placed at any location and heat-formed. Integral injection molding requires expensive molds and is suitable for mass production.
The position of the handle cannot be changed freely.

Extrusion molded products can be made into any length, so the handle can be placed anywhere, heated, and then press-molded to create a handle-like product. There are far-infrared rays, hot air, boiling water, steam, etc., but far-infrared rays are the simplest and most effective in terms of equipment, and they do not take up much space and are convenient to move.

Male and female molds are used for press molding, but wooden molds are sufficient for small-scale production. For mass production, there is a risk of deformation with wooden molds, so if you use cast iron or aluminum molds, there will be no deformation and productivity will be good.

The handle can be formed into any shape, such as a bulge connected to a flat plate, a concave shape, an arc shape, or a rectangular shape.

In addition, the female mold is a mold with the desired shape, but the male mold does not necessarily have to be the same shape as the desired shape. They discovered scales that can be formed into desired shapes, such as an arc or a circular shape connected to a flat plate. First of all, this method requires only the female mold to be made and the male mold to be pressed, so it is very advantageous in terms of cost, and is suitable for high-mix, low-volume production.It is easy to finish and produces beautiful and excellent shapes. It is an excellent product that can be easily installed as a decorative board with handles for furniture such as Japanese and Western chests of drawers or kitchen furniture, and has a good appearance and is inexpensive.
