くても、優れた外観のモールディングが得られる。In the molding manufacturing method of the present invention, the synthetic resin molded product is heated to soften the inside, and when the cutting blade is advanced from the outside surface with the outside surface being harder than the inside, the outside surface Because of its high hardness, it is pushed by the cutting blade without being cut or broken, and the softened resin inside moves to the periphery. When the cutting blade moves further in this state, the outer surface of the cutting part deforms into a curved shape while maintaining an appearance continuous with other parts, and is cut with a curved end formed. The cut surface is formed with a narrow width on the back side without exposing the internal resin, so it is not noticeable from the outside surface side, and a molding with an excellent appearance can be obtained without the need for terminal treatment such as an end cap.

れ、そのままの状態で使用可能である。The manufacturing method of the molding 2z is that the synthetic resin molded product 2 manufactured by extrusion molding, injection molding, etc. of synthetic resin is
As shown in the figure, the molded product 2 is placed on the cutting device 1, and the hydraulic cylinders 9 and 10 are opened to move the clamp 7.8 forward and clamp the molded product 2. At this time, the pedestal 6 and the stopper 21 are positioned by the fluid pressure cylinder 19. Then, a high frequency voltage is applied between the high frequency electrode 15 and the earth electrode 5, and the resin near the cut portion 17 of the molded product 2 is heated by high frequency dielectric heating. By high-frequency dielectric heating, the resin near the cut portion 17 of the molded product 2 is heated equally to a temperature higher than room temperature on both the outer surface 2a and the inside 2b, but since the outer surface 2a is cooled by air at room temperature, the inside The temperature is lower than that of 2b. Therefore, when heated to such an extent that the inner part 2b is softened, the outer surface part 2
The hardness of the inner part a is higher than that of the inner part 2b. In this state, the fluid pressure cylinder 13 moves the cutting blade 12 as shown in FIG.
When the inner surface 2b is advanced from the outer surface side, the outer surface portion 2a is hard, so as shown in FIG. The resin moves to the periphery. At this time, since the tapered surface 12a is formed on the cutting portion I4 side of the cutting blade 12, the resin is extruded along the tapered surface 12a. When the cutting blade 12 further advances in this state, as shown in FIG. 7, the outer surface portion 2a of the cutting portion 17 that will become the molding 22 deforms into a curved shape while maintaining an appearance continuous with other portions. Then, the molding 22 is cut with the curved end portion 23 formed, and a molding 22 as shown in FIGS. 8 to 10 is manufactured. The cut surface 24 formed by the cutting blade 12 is formed near the back surface 2c, with the resin in the interior 2b not exposed to the outside surface, and the outer surface 2a and the back surface 2c bonded together. Not noticeable from the side. Therefore, the molding 22 with an excellent appearance can be obtained without terminating the cut surface 24 with an end cap or the like, and can be used as is.

Although the core material 25 and the decorative film 26 are cut in the same manner as described above by the shaped cutting blade 12, the core material 25 and the decorative film 26 are not cut or broken by the cutting blade I2 together with the outer surface portion 2a, but are pushed to be stretched as they are, and the final It is cut while being adhered to the back surface portion 2c, and a cut surface 24 is formed near the back surface portion 2c. Therefore, the decorative film 26 is continuous even at the end portion 23,
Moreover, the cut surfaces of the core material 25 and the decorative film 26 are also less noticeable. It is preferable that the core material 25 be made of the same color as the resin of the molded product 2 or transparent because it will not be noticeable even if exposed.

A single injection mold can be used to produce moldings with different dimensions or molding shrinkage rates, such as molding articles of different materials. Furthermore, although it is preferable that fJFile exists, it does not necessarily need to exist. Furthermore, it is preferable to form a slippery film of polytetrafluoroethylene resin or the like on the cutting edge of the cutting blade 12. Also, the cutting blade 12
It is preferable to cool the cutting edge and the outer surface 2a of the molded product 2 by blowing cold air at a constant temperature, since this prevents the temperature of the cutting edge from rising and also ensures that the outer surface 2a is lower than the inside 2b.
