Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for manufacturing a drawer front plate with a pull that enables efficient production of a drawer front plate with a pull that has excellent strength stability and appearance. be.

(Prior art and problems to be solved by the invention) Pulls on drawer front plates have conventionally been installed by attaching a handle to the front plate, or by providing a predetermined recess in the front plate and attaching a handle fitting to the recess. was forming. Therefore, in any case,
There is the trouble of having to attach the handle later, which lowers work efficiency. In the former case in particular, there is a problem in that the protruding handle not only gets in the way, but also spoils the appearance of the door, etc. On the other hand, even in the latter case, the aesthetically unnatural appearance of the handle part could not be eliminated because the handle lacked aesthetic integrity with the surrounding parts.

An example of a manufacturing method for drawer fronts with pulls that solves some of these problems is
The manufacturing method disclosed in Japanese Patent No. 32673 can be mentioned. The manufacturing method will be explained based on FIGS. 4 and 5. An auxiliary frame c having a notch b is attached to the inner side of the peripheral edge of a top plate a made of a thermoplastic resin sheet, and then a vacuum forming method is applied. A drawer front plate e with a pull is manufactured by bringing the top plate a and the auxiliary frame c into close contact with each other and having a pull d on the peripheral edge. However, when this manufacturing method is used, the following problems occur. Ta. That is, when using this manufacturing method, there was a problem in which it was extremely difficult to form the pull part by deep drawing. Furthermore, even if the molding can be done to some extent, wrinkles are likely to occur in the handle part, and therefore, there is a problem that it is difficult to integrate the top plate a and the auxiliary frame c while ensuring good appearance and strength stability. It was hot.

When using this manufacturing method, considering its moldability, a relatively thin thermoplastic resin sheet must be used as the material, and therefore the rigidity of the molded product formed is relatively low. Therefore, when manufacturing a desired drawer front plate by filling the inner surface f of the molded body with a filler g such as a foam, a problem arises in that the work cannot necessarily be carried out easily. In addition, in order to manufacture the required drawer front plate, it is necessary to form a molded body with an auxiliary frame in advance, and then go through a process of filling the inside of the molded body with a filler, which makes the process complicated. It is difficult to make the production line continuous, which leads to problems of poor production efficiency and increased production costs.

When using this manufacturing method, it is necessary to use a thin sheet as the material, and the molded body has an open inner surface and has relatively low rigidity. There is a risk that the filler filled in the inner surface will peel off, so complete integration of the two cannot be expected, and for this reason, the obtained molded product will only function as a decorative plate and will not be used as a molded product. The effect of reinforcing the filler was not as expected.

It is an object of the present invention to provide a method for manufacturing a drawer front plate with a handle that can solve these problems.

(Means for Solving the Problems) The method of manufacturing a drawer front plate with a pull of the present invention (hereinafter referred to as the manufacturing method) is a method of manufacturing a drawer front plate with a pull handle (hereinafter referred to as a manufacturing method). The hollow outer cover 1 is formed by pasting a synthetic resin decorative soft sheet material (sheet material with flexibility in thermal deformation) 7 on at least the entire front surface 6 of the hollow plate body 5. After the core plate 2, which has a pull recess 22 inclined with respect to the surface 19 on the surface 19 that contacts the front surface 20 of the core plate 2, is tightly packed, the core plate 2 is allowed to function as a recess. , a portion of the hollow outer cover 1 facing the recessed portion 22 for the handle is depressed by pushing a convex die 26 heated to a required temperature so that the portion opposite to the recessed portion 22 for the handle is brought into substantially intimate contact with the recessed portion 22; This is characterized in that the hollow outer cover 1 and the core plate 2 are closely integrated.

(Example) Examples of the present invention will be described below based on the drawings.

FIG. 1 illustrates a hollow outer shell 1 and a core plate 2 used in carrying out the manufacturing method of the present invention, and also shows a third
Figure 3 illustrates a drawer front plate 3 with a handle obtained by the manufacturing method of the present invention.

The hollow outer cover 1 is formed by pasting a decorative soft sheet material 7 on at least the front surface 6 of a hollow plate 5. The hollow plate body 5 is an extrusion molded body of synthetic resin such as hard vinyl chloride, and as shown in FIG. In this case, upper and lower flanges 10 and 11 are projected at an interval corresponding to the thickness of the bottom plate 12 of the drawer, and both flanges 10 and 11 form a holding groove 13 for holding the end of the bottom plate 12. ing. In this embodiment, the decorative soft sheet material 7 is made of vinyl chloride soft sheet material that has excellent affinity with the hollow plate 5, and its surface is embossed with a woodgrain pattern, for example. has been done. The decorative soft sheet material 7 has the embossed surface facing forward, and covers the front surface 6, upper and lower surfaces 15, 16, and rear surface 9 of the hollow plate body 5.
It is affixed to the upper part of the .

The core plate 2 has a rectangular plate shape that is tightly housed within the hollow outer cover 1, and is made of wood. In addition, a pull recess 22 is recessed approximately in the center of the front surface 19, that is, the surface that abuts the front surface 20 of the hollow outer cover 1. As shown in Figure 1, the surface 1
9, it is formed at an angle of about 45 degrees upward, for example. Note that the pull recesses 22 may be provided on the left and right sides of the core plate 2.

However, in order to carry out the present invention, first, the core plate 2 formed in this way is housed in the hollow outer shell 1 so that the handle recess 22 faces the front surface 20 of the hollow outer shell 1. to wear Thereafter, as shown in FIG. 2, for example, the hollow outer cover 1 containing the core plate 2 is supported by the V block 25 so that the portion 23 facing the pull recess 22 faces upward, and the 22 is made to function as a concave part, and a convex part 26 heated to a predetermined temperature is made to function as a concave part 2 for the handle.
2 and recess the facing portion 23 so that it comes into close contact with the pull recess 22 to form a pull pull 27 as shown in FIG. When recessing the opposing portion 23, if the hollow outer cover 1 is configured with only the hollow plate 5,
The so-called whitening phenomenon occurs on the surface of the handle 27 due to stretching of the resin, but since the soft cosmetic sheet material 7 is attached to the front surface 6 etc. of the hollow outer cover 1 as described above, No whitening phenomenon appears on the 27th side of the handle. The reason for this is that the decorative soft sheet material 7 is flexible and easy to stretch, so even if it is deformed by heating, it will stretch freely without whitening, and as a result, the above-mentioned This is because it effectively covers up the whitened surface.

(Effects of the Invention) The manufacturing method of the present invention stores a core plate having a pull recess in a hollow outer cover made of an extruded hollow plate, and connects the core plate with the pull recess of the hollow outer cover. Since the facing part is recessed by pressing a heated convex shape and the facing part is brought into close contact with the recessed part for the handle to form the handle, the drawer front plate with the handle can be directly connected to the extrusion molding line. By going through simple steps on a relatively short molding line, it can be manufactured continuously, efficiently, and at low cost.

Since the manufacturing method of the present invention forms the handle by pressing a convex shape, it is possible to reliably integrate the hollow outer cover and the core plate without creating wrinkles in the handle. In addition, since the hollow outer cover is made by pasting a decorative soft sheet material on at least the front surface of the hollow plate, when recessing the part of the hollow outer cover that faces the recessed part for the handle, it is necessary to The free stretching action of the soft sheet material reliably prevents whitening from appearing on the handle surface, and various patterns such as woodgrain patterns can be applied to the surface of the decorative soft sheet material by embossing etc. Therefore, the front panel can be made with excellent design effect.

As described above, according to the present invention, it is possible to manufacture a drawer front plate with a handle with a good appearance.

The hollow envelope used in the manufacturing method of the present invention positively reinforces the core plate. Firstly, because it is formed using a hollow plate with a substantially rectangular cross section formed by extrusion molding, its wall thickness is greater than that of the sheet formed by the vacuum forming method described above. This is because the hollow envelope can be set to be thick, the second reason is that the hollow envelope has a rectangular tube shape and its rigidity is high, and the third reason is that
This is because the hollow outer cover assumes a pipe shape in this way, and the hollow outer cover and the core plate become completely integrated in the state in which the handle is formed.

As described above, according to the present invention, it is possible to manufacture a drawer front plate with a pull that has excellent strength and stability including the pull portion.
