It has been proposed to form a coating film on the surface of an M molded product by an in-mold coat molding method. The in-mold coat molding method for this RIM molded product is performed by filling a cavity of a mold, which is usually composed of an upper mold and a lower mold, with a RIM raw material to mold the RIM molded product, and then forming the RIM molded product in the mold. The paint is injected from the paint injection hole of the upper mold into the gap between the surface of the RIM molded product and the cavity surface of the upper mold caused by the contraction of
This is a method of forming a coating film on the surface of an M molded product.

Depending on the application of the RIM molded product, the feel may be hard and unsuitable. Further, even if the thickness of the coating film is increased, the soft feeling of the coating film is not improved so much, and further improvement of the soft feeling is demanded.

On the other hand, the lower mold 31 has a cavity surface 32 forming the front surface of the molded product, and a paint injection hole 33 is formed at a predetermined position on the cavity surface 32. A head 42 of the paint pouring machine is provided in the paint pouring hole 33.
Is connected. The paint injecting machine used in this embodiment is a known paint injecting machine for two-component urethane-based paint which is divided into a polyol side and an isocyanate side, and an air loading device 50 for mixing air bubbles is connected to the polyol side. There is.

た。The air loading device 50 is a device which is connected to a polyol side tank of a paint injecting machine and mixes air bubbles by injecting air into the polyol side paint in the tank. For the purpose, those used in the RIM molding machine can be used.
The air pressed into the polyol-side paint by the air loading device 50 is dispersed in the polyol-side paint as fine bubbles by stirring the polyol-side paint in the tank. The amount of the air mixed is preferably 10 to 40% by volume. By mixing air bubbles in the polyol-side paint, the density of the paint is reduced, and a soft feeling can be imparted to the coating film formed on the surface of the RIM molded product. The size of the bubbles generated by the air loading device 50 is preferably about 8 to 23 μm, and the density of the paint is about 0.8 to 0.9 g / cm 3 . The density of the coating material when air bubbles were not mixed was about 1.1 g / cm 3 .

The in-mold coat molding method of the molded product will be described.
First, as shown in FIG.
The cavity 11 is filled with M raw material 51a. The filled RIM raw material 51a fills the inside of the cavity 11 and is immediately cured to form the RIM molded product 51.

が好ましい。The RIM molded product 51 molded in the mold 10 shrinks as a whole as shown in FIG. 2 due to the progress of the curing reaction, and the lower mold cavity surface 32 and the RIM molded product 5 are formed.
A gap S is formed between the surfaces. The gap S is usually 20 to 60 μ, though it depends on the in-mold coating material used.
It is preferable to set the filling amount of the RIM raw material and the like so as to be about m.

ことができるようになっている。However, as shown in FIG. 5, if the locking portion 23 of the RIM molded product is formed on the cavity surface 22 of the upper mold, the RIM molded product locked by the locking portion 23 can be molded. As shown by the chain line in the figure, the RIM molded product surely contracts to the upper mold side in a state of being locked to the upper mold cavity surface 22, so that there is always a gap between the RIM molded product and the lower mold cavity surface 32. Can be formed. The locking portion 23 is provided at least on the upper mold cavity surface 22 at a position facing the paint injection port 33, and the RIM near the paint injection port 33 at the time of the contraction.
It is preferable that the molded product does not contract toward the lower mold 31 or bend to prevent the paint injection port 33 from being blocked. Further, the locking portion 23 of this embodiment has a concave shape in which the inside is enlarged so that the RIM molded product in the cavity can be locked securely.

The bubble-containing paint 15 is injected into the gap S between them. The bubble-containing paint 15 is preferably a two-component urethane-based paint for in-mold coating, in which bubbles are mixed by using the air loading device 50 as described above. Further, the bubble-mixed coating material 15 allows the bubbles to flow in the gap S.
The viscosity at the time of injection is preferably adjusted to 1000 cps or less. The viscosity can be adjusted by adjusting the paint temperature and the mold temperature. In addition, an auxiliary agent such as a foam stabilizer is appropriately added to the paint, if necessary.

Causes bubbles to rise in the paint and move toward the upper mold cavity surface 21 side, and forms a skin layer with few bubbles near the lower mold cavity surface 31. As a result, the coating film formed on the surface of the RIM molded product 51 by curing the bubble-containing paint 15 becomes a smooth surface without pinholes due to bubbles, and the bubbles are dispersed in the coating film. Therefore, it becomes soft. FIG. 4 shows a part of the molded product, 51 is a RIM molded product, 16 is a bubble, and 17 is a coating film. Then, the mold is opened and the RIM molded product is demolded.
The surface of the obtained molded product is covered with a beautiful coating film which is excellent in softness and has no pinholes on the surface.

Since a paint mixed with bubbles is injected into the gap between the surface of the M molded product and the surface of the mold cavity to form a coating film on the surface of the RIM molded product, a soft coating film can be easily formed due to the presence of the bubbles. Furthermore, since the bubble-containing paint is injected from the lower mold side, it is possible to reliably prevent pinholes due to the mixed bubbles from being generated on the coating film surface, and it is possible to obtain a molded product having a good appearance. .
