- the key top 3 previously formed and decorated separately is bonded to the surface of the raised portion 6b of the key pad 2 exposed from the through hole 4 of the semi-finished product via an adhesive. Thereby, the final cover member for the push button switch is obtained.
- the heating temperature at the time when the above-mentioned molding die is filled with the selective adhesive silicone rubber and heated is equal to or higher than the temperature required for the selective adhesive silicone rubber to cure, and the hard base 1 is formed. It is preferable that the temperature is not higher than the deflection temperature under load of the polycarbonate resin.
- the temperature required for the selective bonding silicone rubber to cure is based on whether or not the time required for the degree of curing of the selective bonding silicone rubber to reach 90% is an acceptable time in the manufacturing process. Is determined.
- the time required for the degree of cure of the selectively bonded silicone rubber to reach 90% can be measured by a well-known rheometer.
- the time (T10) required for the degree of cure of the selective adhesive silicone rubber to reach 10% and the time required for the degree of cure of the selective adhesive silicone rubber to reach 90% are obtained.
- the required time (T90) will be described.
- Each time described below is an experimental value measured by the present inventor using a rheometer.
- T10 was 210 seconds and T90 was 339 seconds.
- T10 When the heating temperature was 110 ° C, T10 was 117 seconds and T90 was 210 seconds. When the heating temperature was 120 ° C, T10 was 72 seconds and T90 was 120 seconds. Further, when the heating temperature was 130 ° C, T10 was 48 seconds and T90 was 105 seconds.

If it is set within 4 minutes (240 seconds), the heating temperature is preferably set to 110 ° C or higher.
- a heating temperature of 150 ° C or more was required for integrally bonding silicone rubber and polycarbonate resin. This is because it was necessary to heat at least 150 ° C to cure the silicone rubber.
- the silicone rubber since the selectively bonded silicone rubber is used, the silicone rubber must be cured at a heating temperature (for example, 130 ° C or less) lower than the deflection temperature under load of the polycarbonate resin. Became possible. Thereby, deformation of the polycarbonate resin can be suppressed.
- FIG. 4 is a graph for explaining the feeling when the keytop is pressed by the relationship between the stroke length and the repulsive force.
- the horizontal axis of the graph shown in FIG. 4 is the stroke length S, and the vertical axis is the repulsive force F.
- the repulsive force F of the flat panel depends on the stroke length S and the maximum value and the minimum value indicated by A in FIG. Is represented by a cubic curve.
- the repulsive force F of the silicone rubber film is generally represented by a substantially linear line as shown in FIG.
- the repulsive force F is represented by a cubic curve having a maximum value and a minimum value shown in FIG. You.
- This cubic curve is expressed as a result of adding the repulsion force F of the above-mentioned dish panel and the repulsion force F of the silicone rubber film. Therefore, in this case, when the key top 3 is pressed, a relatively large repulsive force can be obtained even with a small stroke S. Therefore, when the key top 3 is operated, a good click feeling is obtained, and the operability of the key top 3 is improved.
- a hard resin key top 3 previously formed and decorated is provided on a part of the key pad 2 exposed from the through hole 4 of the hard base 1.
- the method of forming key tops is not limited to this.
- a part of the key nod 2 exposed from the through hole 4 of the hard base 1 may be formed into a desired key top shape!
- FIG. 5 is a cross-sectional view of a main part when a part of the keypad 2 exposed from the through hole 4 of the hard base 1 is used as a keytop 3.
- the silicone rubber film is formed on the entire back side of the hard base 1, but it is not always necessary to form the silicone rubber film on the entire back side. That is, if the impact on the circuit board due to the impact on the hard base or the deformation of the node base can be reduced, a silicone rubber film may be formed on a part of the back side of the hard base 1. However, since a silicone rubber film is formed on the entire back side of the hard base 1 to enhance cushioning, the impact on the circuit board due to the impact on the hard base and the deformation of the node base can be further reduced.
- a silicone rubber film is formed on the entire back side of the hard base 1, and a groove 5 is provided on the back side of the hard base 1.
- a film it is not always necessary to provide the groove 5.
- the space provided between the hard base 1 and the molding die (the space provided for forming the silicone rubber film on the entire back side of the node base 1) is reduced by the extra space injected into the molding die.
- it can be used as a space for accommodating various silicone rubbers.
- extra silicone rubber is accommodated in the space provided between the hard base 1 and the molding die, a situation may occur in which the silicone rubber film is not formed on the entire back side of the hard base 1.
- a groove 5 is provided in the hard base 1 and a silicon This eliminates the need for a mechanism for forming a cone rubber film. Generally, it takes a certain amount of time for silicone rubber, which is a thermosetting resin, to harden when heated. Therefore, the fluid silicone rubber filled in the grooves 5 of the hard base 1 at the time of injection molding enters the back surface of the hard base 1 before being hardened. As a result, a thin silicone rubber film (about 0.01 mm) is inevitably formed on the entire surface or a part of the rear side of the hard base 1.
- a rib for accommodating excess silicone rubber is separately provided outside the outermost peripheral portion of the product. It may be provided. In this case, it is preferable to provide a so-called bite (a thin portion for separating the rib) between the rib and the product. This is because the ribs filled with the excess silicone rubber can be easily separated from the product by providing the pits. Further, by providing the ribs outside the outermost peripheral portion of the product, it is possible to prevent the base material from being damaged by burrs generated at the biting portion.
- the thickness of the silicone rubber film is 0.01-0.4 mm It is preferably about However, when importance is placed on good cushioning properties, it is preferable that the thickness is about 0.1 to 0.4 mm.
- a decorative layer formed by printing, painting or the like is formed on the upper layer of a product in order to improve the appearance of a pattern or the like. Therefore, for example, in a conventional product in which a silicone rubber film is formed on a hard base, a decorative layer is formed on a silicone rubber film. The decorative layer in such a conventional product is formed on the silicone rubber film after the hard base and the silicone rubber film are molded.
- the surface of the silicone rubber film is generally uneven, it is difficult to form the decorative layer by screen printing, and the printing method is limited.
- the decorative layer is formed by painting, masking is required for a portion that does not require painting (for example, a surface to which a keytop is adhered), thereby lowering work efficiency.
- the silicone ink or paint is thermosetting, it must be heated when forming the decorative layer.
- the hard base (polycarbonate resin) formed integrally with the silicone rubber film is thermoplastic and therefore deforms due to repeated heating weak to heat. As described above, when the decorative layer is formed on the silicone rubber film, various problems occur.
- the silicone rubber film is formed on the back side of the hard base 1, before the hard base 1 and the silicone rubber are integrally molded, they are applied on the hard base 1 in advance.
- a decoration layer can be formed. Therefore, coating can be easily performed without requiring masking. Further, since the surface of the hard base 1 is smooth and has no irregularities, screen printing can be easily performed.
- the polycarbonate resin that forms the hard base is compatible with various inks and paints, and therefore has a wide selection range of inks and paints. Therefore, it is also possible to use ink or paint having thermoplasticity.
- the decorative layer can be formed at a low temperature. In this case, the decorative layer is formed on the hard base after integrally molding the hard base and the silicone rubber. In addition, the decorative layer can be easily formed without deforming the hard base (polycarbonate resin).
- a molding die includes a fixed-side die having a gate and a movable-side die arranged to face the fixed-side die. Then, the upper side of the semi-finished product (for example, the raised portion 6b) is formed by the fixed die having the gate, and the lower end of the semi-finished product (for example, the pressing projection 6a) is formed by the movable die. After the semi-finished product is formed, first, the gate portion and the semi-finished product are separated, and then the movable mold is moved. Then, the semi-finished product attached to the movable mold is removed from the mold.
- the semi-finished product for example, the raised portion 6b
- the lower end of the semi-finished product for example, the pressing projection 6a
- the semi-finished product separated from the gate part is attached to the movable mold, and the semi-finished product with the movable mold force is removed using a robot or the like. Therefore, if the semi-finished product does not always adhere to the movable mold, the working efficiency is greatly reduced. Therefore, it is necessary to securely attach the semi-finished product to the movable mold.
- the silicone rubber film is formed on the entire rear surface on the lower side of the semi-finished product, and most of the upper surface of the semi-finished product is formed of a hard base made of polycarbonate.
- the silicone rubber film has higher adhesiveness to a molding die than a polycarbonate resin. Therefore, the lower side of the semi-finished product having a larger surface area of the silicone rubber film is more likely to adhere to the mold.
- the molded semi-finished product can be securely attached to the movable mold. Therefore, work efficiency can be improved and productivity can be increased.
- the molding die is a die attached to a horizontal molding machine, and includes a movable mold 50 and a fixed mold 50 which is arranged to face the movable mold 50. Dies are roughly classified into 60.
- the fixed mold 60 is provided with a gate 61 for injecting a material.
- a cover member for a push button switch is manufactured by the following procedure. Build. First, the hard base 1 is placed in the movable mold 50. Next, the movable mold 50 is moved in the direction of the fixed mold 60. After the movable mold 50 moves to a predetermined position, the selective adhesive silicone rubber is injected from the gate 61 of the fixed mold 60. Next, the selective adhesive silicone rubber filled in the molding die is heated and cured, and the hard base 1 and the keypad 2 are integrally formed to form a semi-finished product. Next, the movable mold 50 is moved away from the fixed mold 60, and the semi-finished product adhered to the movable mold 50 is removed. By attaching a key top to the detached semi-finished product, a cover member for a push button switch is obtained.
- the molding die shown in FIG. 6 is a molding die attached to a horizontal molding machine, it goes without saying that the same effect can be obtained even with a molding die attached to a vertical molding machine.
- a molding die attached to a vertical molding machine generally, a fixed die having a gate is disposed at an upper portion, and a movable die is disposed at a lower portion. Therefore, if the semi-finished product adheres to the fixed mold located on the upper side, the extra force required to remove the semi-finished mold from the fixed mold is attached to the horizontal molding machine. Large compared to the molding dies used. Therefore, the effect of attaching the semi-finished product to the movable mold in the molding die attached to the vertical molding machine is significantly greater than the effect of the molding die attached to the horizontal molding machine. Can be improved and productivity greatly increased.
