(See Patent Document 1).

JP 2000-127198 A

  The transparent insert material 3 described above is, for example, a synthetic resin or a glass plate. However, depending on the material of the insert material, it may be difficult to form a positioning recess. In addition, since the resin portion formed on the outer periphery of the transparent insert material 3 is generally low in strength, when an external force such as a bending force acts on the resin molded product, the joint between them is loosened and the insert material 3 is formed. It may come off from the resin part. In the conventional resin molded product in which the resin part is formed on the outer periphery of the transparent insert material as described above, the durability of the resin part is not sufficient, and there are still points to be improved in the product itself and the manufacturing method. It was.

  An object of the present invention is to provide a resin molded product in which the strength of a resin portion formed on the outer periphery of a transparent insert material is improved, a mold for its production, and a method for producing the resin molded product. is there.

  The 1st characteristic structure of the resin molded product which concerns on this invention is a back surface covering the transparent insert material, the metal frame material arrange | positioned on the outer periphery of the said insert material, and the said insert material and the said frame material A pressure-sensitive adhesive sheet that is bonded from the side, surrounds the insert material, and forms a resin portion in a state of being engaged with at least a part of the peripheral edge portion of the frame material.

  With this configuration, the portion surrounding the outer periphery of the insert material of the resin molded product has a two-layer structure in which the resin portion covers the upper portion of the frame material, and the resin portion around the transparent insert material is reinforced by the metal frame material. . That is, even if an external force such as a bending force acts on the resin molded product to deform the resin portion, the metal frame material positioned below the resin portion prevents the resin portion from being deformed. Thus, a resin molded product in which the insert material and the resin portion were firmly joined was obtained.

  In addition, since the resin portion is formed in a state in which it is engaged with at least a part of the peripheral edge portion of the frame material, the shrinkage force of the resin acting when the resin portion of the resin molded product is molded is not limited to the insert material but the frame material. Also acts in a distributed manner. As a result, the shrinkage force of the resin applied to the insert material became small, and the deformation of the insert material could be suppressed as much as possible by the shrinkage force of the resin. In addition, since the insert material and the frame material are bonded from the back side by the adhesive sheet, the insert material and the frame material are integrally disposed in the resin molded product. The pressure-sensitive adhesive sheet also serves to prevent scattering of the insert material when the transparent insert material is a material that is scattered by receiving an external force such as glass.

  The 2nd characteristic structure of the resin molded product which concerns on this invention exists in the point provided with the clamping part which clamps at least one part among the peripheral parts of the said frame material in the thickness direction of the said frame material in the said resin part.

  With this configuration, it is possible to more reliably suppress the peripheral portion of the frame material of the resin molded product from being sandwiched by the sandwiching portion of the resin portion from the thickness direction of the frame material and the frame material being separated from the resin portion. For example, even when a resin molded product is heated and cooled and a shearing force based on a difference in coefficient of thermal expansion occurs between the resin part and the frame material, or when an external force such as a bending force acts on the resin molded product A sufficient resistance can be exhibited by the sandwiching portion. Further, by providing the resin portion with the sandwiching portion, the contraction force of the resin portion is dispersed in the insert material and the sandwiching portion. As a result, the shrinkage force of the resin applied to the insert material is further reduced, and it is possible to further suppress problems such as the insert material being deformed or damaged due to the excessive shrinkage force of the resin.

  A third characteristic configuration of the resin molded product according to the present invention is that a positioning engagement portion is formed on the frame material.

  With this configuration, the engaging portion for positioning is processed in the metal frame material in the composite insert material, and the positioning processing is not required in the transparent insert material. In addition, since the positioning engaging portion is formed in the frame material covered with the resin portion surrounding the insert material, the aesthetic appearance of the transparent insert material visually recognized from the outside is not impaired.

The characteristic structure of the metal mold used for the production of the resin molded product according to the present invention is that a metal frame material is disposed on the outer periphery of a transparent insert material, and is bonded with an adhesive sheet across the insert material and the frame material. A mold used to manufacture a resin molded product that surrounds the insert material of the composite insert material that is formed and that is engaged with at least a part of the peripheral edge portion of the frame material.
A first mold in which the composite insert material is arranged so that the pressure-sensitive adhesive sheet is in contact with the adhesive sheet;
A suction part provided in the first mold, for sucking the frame material and holding the composite insert material;
And a second mold that clamps the first mold and forms a cavity for resin injection between the first mold and the side portion of the insert material.

  With this configuration, a cavity formed by clamping the first mold and the second mold by sucking the frame material by the suction portion provided in the first mold in which the composite insert material is disposed, and holding the composite insert material The desired resin molded product is manufactured by injecting resin into the resin. Therefore, the suction trace by the suction of the composite insert material is formed on the frame material, and the suction trace does not remain on the insert material. As a result, the aesthetic appearance of the transparent insert material visually recognized from the outside is not impaired.

The first characteristic means of the method for producing a resin molded product according to the present invention is that a metal frame material is disposed on the outer periphery of a transparent insert material, and the adhesive material is bonded to the insert material and the frame material with an adhesive sheet. And forming a composite insert material,
Arranging the composite insert material in the first mold;
Clamping the first mold and the second mold to form a resin injection cavity between the first mold, the second mold, and the side of the insert material;
The method includes the steps of injecting resin into the cavity and filling the resin around the insert material.

  By this characteristic means, a resin that surrounds the insert material of the composite insert material in which a metal frame material is arranged on the outer periphery of the transparent insert material and is bonded with an adhesive sheet across the insert material and the frame material. A resin molded product having a portion could be manufactured. As a result, as described in the characteristic configuration of the resin molded product according to the present invention, a resin molded product in which the insert material and the resin portion are firmly bonded was obtained.

  Moreover, since the composite insert material is formed in the first mold after forming the composite insert material in which the transparent insert material and the frame material are bonded with the adhesive sheet first, the composite insert material is related to the mold in the mold. The positional deviation between the insert material and the frame material is suppressed. Thus, a good resin molded product in which the positions of the insert material and the frame material in the composite insert material were maintained could be easily manufactured. The pressure-sensitive adhesive sheet also serves to prevent scattering of the insert material when the transparent insert material is a material that is scattered by receiving an external force such as glass.

  According to a second feature of the method for producing a resin molded product according to the present invention, in the step of forming the composite insert material, the frame material including an engaging portion for positioning is used, and the first mold is In the step of arranging the composite insert material, the composite insert material is positioned by engaging the engaging portion of the frame material with the position fixing portion provided in the first mold.

  By this characteristic means, the engaging portion provided in the frame material of the composite insert material is engaged with the position fixing portion provided in the first mold, and the composite insert material is positioned on the first mold. That is, since the engaging portion for positioning of the composite insert material is provided not on the transparent insert material but on the metal frame material, the processing of the engaging portion for positioning becomes easy, and the resin molded product becomes easy. It can be manufactured. Moreover, since the engaging part for positioning is formed in the frame material covered with the resin part surrounding the insert material, the beauty of the transparent insert material visually recognized from the outside of the manufactured resin molded product is impaired. There is nothing.

  The 3rd characteristic means of the manufacturing method of the resin molded product which concerns on this invention has the process of arrange | positioning a decorating sheet to the said 2nd type | mold before the said 1st type | mold and the said 2nd type | mold clamping. It is in.

  By this feature means, a metal frame material is arranged on the outer periphery of the transparent insert material, and the resin molded product surrounding the insert material of the composite insert material bonded with an adhesive sheet across the insert material and the frame material. At the time of manufacturing by resin injection, simultaneously with the molding of the resin part, the surface of the resin part is decorated with a decorative sheet.

The resin portion 7 is formed so as to surround the insert material 3 and engage with at least a part of the peripheral edge portion 4A of the frame material 4, and includes the following manufacturing process. It is manufactured through.

[First Embodiment]
[Process for forming composite inserts]
The transparent insert material 3 is, for example, glass or an acrylic plate, and is formed in a flat plate shape. The metal frame material 4 disposed on the outer periphery of the insert material 3 is made of stainless steel or the like, and is formed in a flat plate shape that is thinner than the thickness of the insert material 3.

  In order to form the composite insert material 6, first, the frame material 4 is arranged on the outer periphery of the insert material 3, and one surface of the insert material 3 and one surface of the frame material 4 are arranged flush with each other. Thereafter, the insert material 3 and the frame material 4 arranged in a flush manner are bonded together with an adhesive sheet 5 to form a composite insert material 6 shown in FIG. An engagement portion 4a for positioning that engages with a position fixing portion of the mold is provided at a predetermined position of the frame material 4. In FIG. 1, the engaging portion 4a is formed of a hole, but the engaging portion 4a may be a concave portion. In addition, the adhesive sheet 5 bonded across the insert material 3 and the frame material 4 is a material of the insert material 3 when the transparent insert material 3 is a material that is scattered by receiving an external force such as glass. Also serves to prevent scattering.

Next, the metal mold | die used for manufacture of the resin molded product which concerns on this invention is demonstrated.
