Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a molded product formed by a pattern coating film having a contour line of a predetermined shape and a molded product manufactured by this manufacturing method, including a wheel cover, a finisher, a plastic container and the like. The present invention relates to a method for producing a coating film having a predetermined pattern on the body of a molded article and a molded article manufactured by this method.

2. Description of the Related Art Mask coating is widely used as a method for imparting a pattern to a molded article of this type. In this mask coating, after the molded product is molded into a predetermined shape, the pattern part of the predetermined shape or the part other than the pattern is covered with a mask, and the pattern part or the part other than the pattern is spray-coated to form a coating film. ing.

However, the pattern formed by this mask coating has a poor three-dimensional effect, and it is difficult to produce an excellent three-dimensional pattern.

Further, in order to give a pattern having a three-dimensional effect, it is usual to form an uneven shape on the body of the molded article. However, when the molded article is molded by injection molding of synthetic resin or the like, the uneven portion is formed. Since synthetic resin passes through the corresponding injection mold part, flow marks and weld lines are likely to occur on the surface of the molded product body, and the mechanical strength decreases at the part where these weld lines occur, and at the flow mark part It has the drawback of impairing the appearance.

Therefore, Japanese Patent Application Laid-Open No. 63-175670 proposes a so-called magnetic coating method of forming a pattern on a coating film by utilizing a magnetic field. This is a liquid coating material containing a fine powder magnetic substance is applied to the surface of an article to be coated (molded product) made of a non-magnetic substance such as plastic to form a coating film, and the coating film is still liquid. A pattern is formed by applying a magnetic field in a state where the contained magnetic material can move in the coating film.

In this magnetic coating method, a magnetic field is applied to change the orientation of the fine powdery magnetic substance with respect to the coating film surface, and the magnetic substance is moved or concentrated in accordance with the direction of the magnetic force lines to cause the inside of the coating film to be changed. It is what makes the pattern appear.

[0007]

However, in the magnetic coating method described in the above-mentioned publication, it is difficult to maintain the regularity of the deviation of the magnetic material partially accurately, and therefore the pattern of the approximate shape is obtained. There is no problem when forming a film on the coating film, but a predetermined pattern (in this case, a pattern having a pattern of a predetermined size, the thickness of the contour line forming the pattern, the contrast between the contour line and other parts, etc.) When it is desired to form a magnet, there is a problem that it is very difficult to form a magnet corresponding to the pattern. Therefore, when forming a magnet corresponding to a predetermined pattern, it is formed by trial and error.

Therefore, the present invention pays attention to the relationship between the position of the contour line of the pattern and the magnet, and clarifies how to set the shape of the magnet to obtain a predetermined pattern. Provided are a method of manufacturing a molded product having a pattern having a contour of a predetermined shape capable of easily setting the shape of a magnet for forming a predetermined pattern, and a molded product manufactured by this manufacturing method. The purpose is to

[0009]

In order to achieve the above object, the invention according to claim 1 is characterized in that a magnetic substance mixed in the coating film before coating or after coating on the surface of the molded article body is used. When it is movable, it is in non-contact with the coating surface, and the part where the direction of the magnetic force line is parallel to the coating surface is in the position where the magnetic field exerts sufficient magnetic force to move the magnetic substance. It is characterized in that a magnet having a peripheral shape is arranged so as to substantially coincide with the substantially central portion, a magnetic field is formed in the coating film, and the magnetic body is moved along the direction of the lines of magnetic force.

According to a fourth aspect of the present invention, there is provided a molded article produced by the production method according to any one of the first to third aspects, in which a pattern having a contour line of a predetermined shape is formed.

[0013]

EXAMPLES A method for manufacturing a molded product having a pattern having a contour line of a predetermined shape according to the present invention and a molded product manufactured by the manufacturing method according to a first embodiment of the present invention will be described below. FIG. 1 is a front view of a wheel cover that is a molded product showing a nut pattern that is a predetermined pattern. 2 is a sectional view taken along line III-III in FIG.

As shown in FIGS. 1 and 2, a wheel cover 1 as a molded product comprises a wheel cover body 3 and a coating film 5 having a pattern formed on the surface of the wheel cover body 3. The wheel cover body 3 is formed of a plastic material, which is a non-magnetic material, in a substantially disk shape, and is formed so as to form a part of the outer surface of a sphere having a predetermined radius, and the outer surface is a substantially flat surface. Has become. Further, on the back surface side of the wheel cover body 3, eight mounting portions 7 for mounting on a road wheel of a vehicle are provided in a protruding manner. Further, eight ventilation holes 9 are formed so as to penetrate between the mounting portions 7 on the inner side of the mounting portions 7 in the radial direction.

The above-mentioned flat surface is not limited to the outer surface of a sphere having an infinite radius, but actually, a curved surface having a radius of about 100 mm or more may be continuous. That is, the surface of the wheel cover body 3 is a flat surface except for a portion such as the vent hole 9 where the radius of the curved surface is largely changed and the shape is apparently uneven.

The coating film 5 formed on the surface of the wheel cover body 3 of this embodiment has a nut pattern (predetermined pattern) having the contour of four hexagonal nuts as shown in FIG.
11, 11, 11, 11 have been revealed. The contour of the nut pattern 11 is a regular hexagon on the outside and a circle on the inside.

Next, a coating film forming apparatus 13 for forming a coating film that shows a pattern on the surface of the wheel cover body 3 will be described with reference to FIG.

As shown in FIG. 3, a base 1 in which an upper surface 16 is integrally supported by floor-like legs 15a, 15a.
A fixing member 17 made of wood, gypsum, or the like for supporting the back surface side of the wheel cover body 3 is fixed on the wheel 5. A through hole 19 is formed in a substantially central portion of the fixing member 17, and a tubular guide member 21 fixed to the upper surface portion 16 is fitted into the through hole 19. The inside of the guide member 21 is formed in a shape of a skirt having an inclined surface whose diameter is gradually reduced toward the lower part, and the tip end of the holding device 23 is inserted and arranged.

An outer peripheral surface of the tip portion of the holding device 23 is formed with an inclined surface whose diameter is gradually reduced downward, and a grip hole portion 24 opened upward is formed inside thereof. An elastic hole 20 is formed at the lower end of the grip hole portion 24, and the tip end portion has elasticity. An uneven surface is formed inside the grip hole portion 24, and a so-called sprue 26, which is a resin injection portion into the mold during injection molding of the wheel cover body 3, is inserted therein. Further, the lower end portion of the holding device 23 is connected to the tip end portion of the rod of the air cylinder 30 which is fixed on the support plate 28 spanned between the leg portions 15a and 15a.

Therefore, when the rod of the air cylinder 30 is pulled into the main body, the holding device 23 moves downward, and the slope of the outer periphery of the holding device 23 slides on the inside slope of the guide member 21 and moves downward. In this case, by sliding on the inner slope of the guide member 21, the tip portion of the holding device 23 bends inward and the holding hole portion 24 is reduced in diameter, so that the sprue 26 on the back surface side of the wheel cover body 3 is firmly held. At the same time, by pulling the sprue 26 downward, the rear surface side of the wheel cover body 3 is brought into close contact with the fixing member 17.

Further, at the upper surface of the fixing member 17, that is, at the position facing the back surface of the wheel cover body 3, there are four recessed magnet mounting portions 29 for mounting the magnets 27 on a part of the fixing member 17, 29, 29, 29 are provided. These magnet mounting parts 29, 29, 29, 29 are 4
The distance from the upper surface of each magnet 27 to the surface of the wheel cover main body 3 is kept the same.

The nut-shaped magnets 27 are arranged symmetrically with respect to the center P so that the magnets 27 have the same radius with respect to the center of the wheel cover main body 3 and satisfy the circumferential equidistant relation.

Next, a predetermined pattern (nut-shaped pattern) 1
A method of manufacturing a vehicle wheel cover in which the coating film 5 having No. 1 is formed on the front surface side of the wheel cover body 3 will be described.

First, the wheel cover body 3 is molded into a predetermined shape by injection molding. At this time, the surface of the wheel cover body 3 has a gray color. Next, the wheel cover body 3 having a predetermined shape is placed on the fixing member 17 in which four magnets 27 having a shape corresponding to the nut pattern 11 are embedded in the upper surface. At this time, after inserting the sprue 26 portion of the wheel cover body 3 into the grip hole portion 24, the air cylinder 30 is driven to pull the rod into the body,
The outer circumference of the holding device 23 is slid on the inclined surface of the guide member 21 to pull the sprue 26 downward. As a result, the rear surface side of the wheel cover body 3 is fixed in close contact with the upper surface of the fixing member 17. Further, in this state, a magnetic field is formed by the magnet 27 on the surface portion of the wheel cover body 3.
In this case, in the surface portion of the wheel cover body 3, the direction of the magnetic force lines is in the vicinity of the surface of the wheel cover body 3, that is, at a position where a non-contact distance is maintained and the magnetic field exerts sufficient magnetic force to move the magnetic body. The peripheral shape of the magnet 27 is formed so that the position substantially parallel to the surface of the coating film formed on the surface of the wheel cover body 3 substantially coincides with the substantially central portion of the contour line of the nut pattern 11.

A large number of fine flake-shaped magnetic bodies 35 (in the case of this embodiment, the surface of which is silver-white Ni is used).
And a solvent are applied to the surface of the wheel cover main body 3 with a transparent liquid paint 33, for example, with a spray gun 31. Then, the magnetic material 35 in the paint that has reached the surface of the wheel cover body 3
Under the influence of the magnetic field, the posture changes along the direction of the magnetic force lines, and some moves toward the magnet.

This will be described with reference to FIGS. 4 (a) to 4 (d). FIG. 4A shows the relationship between the shape of the nut pattern 11 of the wheel cover body 3 and the shape of the magnet when viewed from the front. In the same figure, the magnet 27 has a peripheral line 2
7a is a regular hexagon, and a round hole 27c is formed in the center, and a nut-shaped magnet having an inner peripheral edge 27b formed by the hole 27c. Two contour lines of the pattern 11 appear, each of the contour line 49a on the outer peripheral edge side and the contour line 49b on the inner peripheral edge side has a predetermined width, and the central portion 49 of each contour line is a solid line. It is shown. In this pattern 11, the contour lines 49a and 49b appear whiter than the other portions, and the central portion 49 is the whitest portion of the contour lines.

In FIG. 4B, a gray-colored portion is a virtual reference line. A portion above the reference line appears whiter than the other portion, and a portion that appears to float above the other portion and the reference line. FIG. 4 is a diagram showing the degree of distribution of a portion that appears black in the lower portion and recedes from the other portions, corresponding to line IV-IV in FIG. 4A.

FIG. 4 (c) shows a typical orientation of the magnetic material in the coating film in each portion in correspondence with the line IV-IV in FIG. 4 (a).

FIG. 4D is a sectional view taken along the line IV-IV in FIG. 4A, showing the relationship between the wheel cover body 3, the coating film 5, the shape of the magnet 27, the magnetic force lines 39, and the magnetic substance 35. Is. In the figure, the magnetic force lines 39 in the magnetic field formed by the magnet 27 are directed in a specific direction in each part in the coating film, and the magnetic body 35 is directed in a specific direction with respect to the surface 37 of the coating film along that direction. Facing.

The above description and FIGS. 4A to 4
As is apparent from (d), in the contour lines 49a and 49b, most of the magnetic material 35 in the coating film 5 is at an angle of 0 ° to the surface 37 of the coating film, that is, substantially parallel to the coating surface 37. Since the amount of reflection of light incident from the front is larger than other portions, it looks whiter than other portions and forms a nut pattern.

Of the contour lines 49a and 49b that appear white, the most white portion is the central portion 49, which is shown by a solid line.

Here, the measurement result of the position where the direction of each magnetic force line 39 generated by the magnet 27 is parallel to the coating film surface 37 in order to form the contour line of the nut pattern 11 will be described. In FIG. 5, the direction of the magnetic force lines 39 of the magnet 27 indicates the coating surface 3
The positions of the parts P1, P2, P3, ... PN parallel to 7 are shown. In this figure, the top surface of the magnet 27 is Y
Assuming that the axis and the side surface of the magnet 27 are the X axis, as shown in FIG. 6, the relationship of Y = 5X is obtained within the range of 0.5 ≦ Y ≦ 7.
When the distance in the Y-axis direction was 7 m / m or more, the contour line was unclear.

According to these results, when the thickness of the article to be coated (distance in the Y-axis direction) is 1 mm, the central portion (distance in the X-axis direction) of the position where the pattern by the contour line is formed is the magnet 27. It is formed at a position separated from the side surface (periphery) by about 1/5 mm. That is, when setting the peripheral shape of the magnet, the direction of the magnetic force line 39 is ⅕ from the position where the direction of the magnetic force line is substantially parallel to the coating film surface 37.
By forming the peripheral edge shape of the magnet 27 so that the peripheral edge of the magnet is located at a position separated by mm, and arranging it at a predetermined position of the molded product, a pattern having a predetermined contour line is moved to a predetermined position. Can be formed.

As described above, when a predetermined pattern (nut pattern 11 in this case) is formed, the position of the contour line of the pattern formed on the coating film 5 is used to correspond to the contour line of the pattern by using the above experimental results. By forming the peripheral shape of the magnet 27 to be recessed in a direction parallel to the surface of the coating film 5, it is possible to easily set the shape of the magnet for obtaining a predetermined pattern. Also,
As for the corresponding peripheral shape of the magnet 27 retracted in the direction parallel to the surface of the coating film 5, when a predetermined pattern draws a complicated contour line, the shape of the contour line pattern may be reduced by substantially similar shapes.

Next, the article to be coated 43 having the thickness T1 and the thickness T
The size of the magnet 47 when a pattern is formed on the second article 45 to be coated will be described. In FIG. 7, α1, α
2 indicates the difference between the central portion of the contour line of the pattern formed on the articles 43 and 45 to be coated and the peripheral edge of the magnet 47. The magnet 47 will be described as an example of a disk-shaped one having a through hole formed in the central portion. The dimension from the center to the outer circumference of the magnet 47 used for the articles 43 and 45 to be coated is S _OUT1 ,
S _OUT2, and the size from the center to the inner circumference is S _IN1 and S _IN2
And Further, the required dimension from the central portion of the contour line located outside the pattern is L _OUT, and the required dimension L _IN from the central portion of the contour line located inside the pattern.

As is clear from this figure, the relationship between the size of the magnet 47 used and the size of the central portion of the defined contour is expressed by the following equation.

S _OUT1 = L _OUT -α1 S _OUT2 = L _OUT -α2 S _IN1 = L _IN + α1 S _IN2 = L _IN + α2 where α1 and α2 are different values depending on the thickness T1 and T2 of the article to be coated, It may be obtained based on the above calculation formula and / or FIG.

From the above equation, the peripheral edge shape is formed in the vicinity of the coating film surface such that the portion where the direction of the magnetic force lines is parallel to the coating film surface substantially coincides with the central portion of the contour line of the pattern, and the corresponding peripheral edge of the magnet. The magnet 47 has a shape that recedes in a direction parallel to the coating surface.
By forming, it is possible to form a contour pattern having a predetermined shape (size).

Further, when the thickness of the article to be coated forming the pattern becomes thicker, when the contour line is formed at the same position, the positions where the directions of the magnetic force lines are substantially parallel to the coating surface are set to the same position. In addition, the peripheral shape of the magnet 47 is made smaller than that of a thin magnet.

In the above embodiment, an example was shown in which a magnet was placed on the back side of the molded product body to form a magnetic field in the molded product body. However, the shape of the back surface of the molded product body is complicated. If it is not possible to place the magnets in close contact,
As shown in, a magnet may be arranged on the surface side (coating surface side) of the molded article body. In this case, assuming that the distance d between the magnet and the surface of the molded article body is the thickness of the molded article, the thickness of the molded article is taken into consideration, and the direction of the magnetic force lines is applied to the position where the contour line of a predetermined pattern is formed. The gap distance d may be set so as to position the portion substantially parallel to the surface, and the dimension between the coating film and the magnet can be freely selected without being limited by the thickness of the article to be coated.

In the first embodiment, the paint in which a large number of fine flake-shaped magnetic materials are mixed is applied in the state where the magnetic field is formed in advance, but this step may be reversed. That is, after the paint is applied, the paint still maintains its fluidity, and while the magnetic substance in the paint film can move and change its direction, a magnetic field is formed from the front side or the back side of the wheel cover 1 to reveal the pattern. You can also let it.

The fine flake-shaped magnetic material used in the present invention is preferably in the shape of a thin plate, and is not limited to its planar shape. Further, the material is preferably a ferromagnetic material such as iron, nickel, cobalt or alloys thereof, and is a substance that is strongly magnetized in that direction by an external magnetizing action. However, it may be a diamagnetic substance such as bismuth, antimony, copper or zinc. The magnetic substance may be the above-mentioned ferromagnetic substance coated with a gold-colored substance or an aluminum-colored substance, or may be colored with a non-magnetic paint. The size is preferably 1 to 50 μ in the longitudinal direction, and more preferably 20 to 50 μ. The thickness is preferably 5 to 20 μ.

The coating material used in the present invention is preferably a resin that can be dried or cured at room temperature, but it may be a heat-curing type or a UV irradiation-curing type. For example, alkyd resin, polyester resin, acrylic resin, urethane resin,
It may be vinyl resin or the like. As the solvent, an organic solvent or water is used. As the volatile solvent, those having dilutability and volatility, such as thinner, are preferable. In particular, if the proportion of a low boiling point solvent such as methyl ethyl ketone is increased, the quick-drying property is improved.

The mixing ratio of the magnetic powder and the vehicle is preferably 10 to 20% by weight per 100 weight of the vehicle.

The spray coater may be one used for ordinary spray coating and is not particularly limited.

When the coating material is a thermosetting type, after the magnetic substance in the coating film does not move, it is exposed to warm air, infrared rays, etc.
It is necessary to heat appropriately. When the paint is UV curable,
Similarly, ultraviolet irradiation with a mercury lamp or the like is required.

In any of the above examples, it is preferable to form a transparent or semitransparent coating film containing no magnetic material as a topcoat on the surface of the coating film containing magnetic material.

The application is not limited to spraying, but includes depping, flow coating and the like.
