る。In order to mold a sheet-shaped resin molded body partially decorated with a decorative skin material using such a mold,
First, as shown in FIG. 1, the cavity mold 1 and the core mold 2 are opened, and the decorative skin material holding surface 1a of the cavity mold 1 sucks the decorative skin material 11 such as a fabric base or any other means. Then, the guide frame 3 is lifted while being temporarily held by attachment, and the peripheral edge portion of the decorative skin material 11 is pressed and fixed by the pressing portion at the tip of the guide frame 3 in the mold open state. in this case,
The decorative skin material 11 is mounted on the end of the guide frame 3 and temporarily fixed, as shown in FIG. 2, instead of being attached to the decorative skin material holding surface 1a in advance by suction or any other means. It is also possible to press and fix the decorative skin material 11 to the decorative skin material holding surface 1a of the cavity mold 1 by raising the guide frame 3 in that state. Next, as shown in FIG. 3, the decorative skin material holding surface 1 a of the cavity mold 1 and the core mold 2 are
The first molten resin A is supplied from the supply gate 4 to the inner cavity portion partitioned by the guide frame 3 between the design surface forming molds 2a.
At the same time, the mold is clamped as shown in FIG. 4 to pressurize the first molten resin A to remove the peripheral portion 11b of the back surface of the decorative skin material 11 which is in contact with the tip of the guide frame 3. A backing layer 10a made of a sheet-shaped resin is formed on a portion of the backing layer 1
The peripheral edge of 0a is hung from the back surface of the decorative skin material 11 as a short leg frame portion 10b formed by the concave step portion 2c at the tip peripheral edge of the design surface forming mold 2a. In the present invention, the above molding process is referred to as a primary molding process, and hereinafter, the molding process up to the final product described below is referred to as a secondary molding process.

１を上昇させるようにしてもよい。Next, as shown in FIG. 5, the guide frame 3 is moved to a position where the pressing surface at the tip thereof is slightly lower than the two mold surfaces of the design surface forming mold 2a and the resin sheet main body forming mold 2b. A space S for resin intervention is formed between the design surface forming die 2a and the resin sheet main body portion forming die 2b by lowering, and the peripheral edge portion 11b of the decorative skin material 11 is released.
In this state, the second molten resin B is supplied through a supply gate (not shown) to the unfilled cavity portion left around the decorative skin material 11 in which the backing layer 10a is molded and integrated in the first molding step. At this time, only the design surface forming mold 2a that moves up and down independently may be slightly raised to further seal the unfilled cavity portion.
In order to prevent the decorative skin material 11 from being crushed by the clamping pressure of the resin sheet main body forming die 2a and the texture of the resin sheet main body forming die 2b from being damaged, the cavity die 1 should be raised in the same manner as the design surface forming die 2a.

り返せばよい。The second molten resin B thus supplied to the unfilled cavity portion is applied to the peripheral portion 11b of the decorative skin material 11 in which the backing layer 10a obtained in the first molding step is integrally formed. The second molten resin B flows toward the outer surface of the peripheral surface 11b of the decorative skin material 11 with the top of the mountain-shaped frame-shaped ridge 1c on the mold surface of the cavity mold 1 as a boundary.
Is partially inserted into the space S for resin intervention between the design surface forming mold 2a and the cavity mold 1 to enter the peripheral edge portion 1 of the decorative skin material 11.
Short leg frame portion 1 continuing to the back surface of 1b and the periphery of the backing layer 10a
0b so as to cover the peripheral edge portion 11b of the decorative skin material 11 and to surround the decorative skin material 11 in the state where the backing layer 10 is provided.
The resin sheet main body 10 reaching the peripheral edge of a is integrally formed. At this time, as shown in FIG.
If the vacuum communication passage 2c communicating with the unfilled cavity portion is provided on the upper side surface of a and the unfilled cavity portion is vacuum-treated, the peripheral edge portion 11 of the decorative skin material 11 will be described.
Since b is easily bent into the gap S of the core mold 2, when the second molten resin B is supplied, the peripheral surface portion 11b of the decorative skin material 11 is surely covered with the second molten resin B. It is more preferable because it can be obtained. After the sheet-shaped resin molded body partially decorated with the decorative skin material 11 is molded in this way, as shown in FIG. 7, after cooling for a certain period of time, the cavity mold 1 and the core mold 2 are molded. The product is opened, the product is taken out, one cycle is completed, and the same molding process is repeated thereafter.

る。In the sheet-shaped resin molded body thus obtained, the backing layer 10a is molded while the decorative skin material 11 forming the design surface is held in the fixed position by the primary molding step. After the integration, the resin sheet main body portion 10 that covers the peripheral edge portion 11b of the decorative skin material 11 and reaches the peripheral edge of the backing layer 10a is integrally formed around the decorative skin material 11 by the second molding step. Because it will be a product
The decorative skin material 11 is formed at a predetermined position without displacement, and there is no burr at the boundary portion between the decorative skin material 11 and the resin sheet main body portion 10 and a high quality product can be obtained. Also,
The first molten resin A and the second molten resin B are basically the same, but different resins can be used.
