Description of the Related Art A molded article which is a base material of a door trim, which is one of automobile interior parts, is a vinyl chloride skin having a foam layer on the surface of a base material formed by molding resin or wood into a door trim shape. The material is generally attached. As a method of sticking the skin material to the base material, the skin material is heated and softened by a heater to cover the base material, and the skin material is sucked by vacuum suction from a vacuum forming mold on which the base material is placed. The method of sticking to, that is, the so-called vacuum forming method is well known.

形貼着することで形成する。FIG. 5 shows an example of a molded product for door trim.
By the way, a decorative cloth may be partially attached to the door trim. At this time, if the peripheral edge portion of the attached cloth is exposed, the appearance is impaired. Therefore, a groove having a depth of about 5 mm is formed in the molded product in advance, and the peripheral edge portion of the cloth is inserted into the groove. I often make it invisible from the outside. Generally, this process is called graining, and the groove used for graining is called graining groove M. The wood grain groove M is formed by molding and adhering a skin material along the groove provided in the base material in advance.

る方法であり、これにより溝の底部において表皮材Sの
浮きのない、状態のよい木目込み溝を形成する。The wood grain groove M can be formed only by vacuum suction. However, in actuality, the skin material may not be pulled to the bottom of the groove by the force of only vacuum suction, and floating may occur. Therefore, a vacuum forming die having a wood cutting blade as shown in FIG. 4 is generally used for forming. The process will be described below. The base material W is placed on the lower mold 12, and the heat-softened skin material S is covered therewith, and the vertically movable wood grain cutting blade 14 is vacuum-sucked into the groove of the base material W at the same time. This is a method of holding the bottom surface of the groove and firmly adhering it, thereby forming a well-grained wood-groove groove in which the skin material S does not float at the bottom of the groove.

溝が形成できなくなる。According to the above method, the groove perpendicular to the direction of movement of the grain cutting blade 14, that is, the groove on the flat surface portion (F portion in the figure) of the state where the substrate W is placed on the vacuum forming die is at the bottom. You can hold it straight down. However, depending on the design of the door trim, the wood grain groove may extend to the upper part (U portion in the figure) of the door trim. In that case, when the base material W is placed on the vacuum forming die, the groove is formed in the moving direction of the wood grain blade 14. Get closer to parallel. In this state, when the woodgrain blade 14 is lowered from above and inserted into the groove, the woodgrain blade 14
Does not press straight toward the bottom, but slides down the bottom to pull the skin material S, and the skin material S is cut or wrinkled, so that a good wood grain groove cannot be formed.
