Definitions
- the present invention relates to a method for bonding a synthetic resin and a metal plate, and more particularly to a method for bonding a synthetic resin and a metal plate, which can obtain a strong bonding state between the synthetic resin and the metal plate.
- the present invention relates to a method for attaching a metal plate pressed by a metal to a synthetic resin injection molding die, and bonding the synthetic resin and the metal plate by injecting the synthetic resin into the die.
- the problem was solved by using a resin injection and adopting a structure for achieving tight adhesion with a synthetic resin at the peripheral portion and other portions of the metal plate.
- metal pressed metal plates 4 and 16 are injection-molded into a synthetic resin mold 1.
- the present invention relates to a method in which the synthetic resin 14, 20 is injected into the mold 10, and the synthetic resin 14, 20 is bonded to the metal plate 4, 16.
- One of the methods is a curl portion 5a in which the metal plate 4 is curved toward the side where the synthetic resin 14 is bonded to the peripheral portion, and the tip 5b side and the metal plate 4 are joined together.
- the curl portion 5a is formed to have a smaller space between the resin 14 and the surface on which the force is adhered than the curl portion 5a (FIG. 1 (d)).
- Synthetic resin of metal plate 4 in mold 10 14 Synthetic resin injected to the surface on which side 4 is bonded 14 Partial force of 4 ⁇ Pressurized injection into curl portion 5 a and metal plate 4 and synthetic resin
- This is a method of bonding a synthetic resin and a metal plate, which is characterized in that 14 and 14 are bonded.
- FIGS. 2 (a) to 2 (c) the surface of the metal plate 16 in the injection molding die 10 on the side where the synthetic resin 20 is bonded is shown. Due to the pressure of the injected synthetic resin 20, it is possible to cause a partial force to be deformed into a concave and convex curved surface in a portion other than the peripheral portion of the metal plate 16. Due to the injection pressure of the synthetic resin 20 into the mold 10, the portion other than the peripheral edge of the metal plate 16 is deformed into a concave and convex curved surface, and the shrinkage when the synthetic resin 20 is hardened is used. The state in which the synthetic resin 20 adheres to the uneven curved surface portion formed in 16 can be strengthened.
- the injection molding die 10 made of synthetic resin and the metal plate 16 mounted in the die 10 are provided with a part other than the peripheral portion of the metal plate 16. It is necessary to have a space to absorb the deformation to the uneven surface in the part.
- the concave and convex portions are present in advance on the surface of the metal plate 4, 16 attached to the injection molding die 10 other than the peripheral portion to which the synthetic resin is bonded. You can also do so. By doing so, the synthetic resin injected and injected into the mold 10 and adhered to the irregularities strongly adheres to the irregularities due to shrinkage during curing, so that the synthetic resin and the metal plate The sticking state can be further strengthened.
- the product obtained by laminating the synthetic resin and the metal plate is attached to the metal plates 4 and 16 in a synthetic resin injection mold 10 and the synthetic resins 14 and 20 are attached. It can be injected into the injection mold 10 to be manufactured as an integrally molded product.
- the shape and size of the product in which the synthetic resin and the metal plate are laminated are greatly restricted.
- synthetic resin having a high shrinkage rate such as PP (polypropylene) or PE (polyethylene)
- the difference in shrinkage rate from the metal may cause deformation of the metal. It is necessary to select the above method in consideration of the use, characteristics, etc., of the product in which the synthetic resin and the metal plate are laminated.
- the metal plate 4 is formed by using air pressure. It can be easily installed in the injection mold 10.
- a method of bonding a metal plate to another synthetic resin proposed by the present invention is to bring a thermoplastic synthetic resin molded product directly into contact with a heated metal plate, and to contact the contact surface. After melting, it is cooled, and the synthetic resin and the metal plate are bonded together by utilizing the shrinkage of the thermoplastic synthetic resin during curing.
- the contact surface of the metal plate 22 can be formed in advance with irregularities as shown in FIGS. 5 (a) to 5 (c). Further, as the heating of the metal plate 22, it is possible to employ the heating by heat or the induction heating by high-frequency or low-frequency current.
- a synthetic resin By attaching a synthetic resin to this, it is a cooker or a tableware with a synthetic resin attached to a metal plate. At normal operating temperatures in cooking, eating and drinking, washing, etc., the metal and the synthetic resin It is possible to provide a cooking device and a food and drink device that do not generate force such as peeling between them. In addition, when viewed in a plan view, it is possible to provide cookers and eating utensils of various shapes and sizes such as a polygon such as a triangle and a rectangle, a circle, and an ellipse.
- Cookers and eating and drinking utensils formed in this way are not limited to the combination in which the inside is a metal plate and the outside is laminated with synthetic resin, but are also formed in the combination of the outside with a metal plate and the inside laminated with synthetic resin. You can also. However, if it is a cooker or a tableware with a metal plate on the inside and a synthetic resin laminated on the outside, it is necessary to use a high-frequency or low-frequency current for induction heating and cooking, etc. to perform heating control and heat retention. , Heating efficiency is good and convenient.
