The skin 1 used in this embodiment is a thin sheet made of resin (for example, polyvinyl chloride; PVC), and the surface is partitioned into a first form 1s and a second form 1t as illustrated in FIG. 1D. It is a two-tone form. The skin 1 has a skin parting line 1a that is a skin parting area that functions as a two-tone partition line. For example, in the skin 1, the first form 1s has a light shade, and the second form 1t has a dark shade. However, it is not limited to this.
[0012]
As shown in FIG. 1 (A), the skin 1 is held on a clamper 2 in an erected state. Therefore, the clamper 2 functions as a skin erection means.
The mold 3 is made of a heat-resistant resin, and includes a mold surface 31 having a convex portion 30 and an appropriate number of suction holes 32 that open to the mold surface 31. The mold surface 31 faces downward and faces the skin 1. On the mold surface 31 of the mold 3, a reference mold surface portion 31c is formed in a concave shape. The reference mold surface portion 31 c is for positioning the skin parting line 1 a of the skin 1. As can be understood from FIG. 1A, the reference mold surface portion 31 c of the mold 3 directly faces the skin parting line 1 a of the skin 1.
[0013]
On the mold surface 31 of the molding die 3, a base material 4 made of wood (for example, a fiber made of wood, hemp, etc., solidified with a phenol resin and stamped and molded) having a plate shape coated with an adhesive is attached. A suction device 38 is connected to the suction hole 32 of the mold 3 via a pipe 38a. When the suction device 38 is activated, a suction action is generated in the suction hole 32.
The assist plug 7 has a plate shape and is made of metal. As can be understood from FIG. 1A, the assist plug 7 is located below the mold surface 31 of the mold 3 and is oriented in a direction substantially perpendicular to the mold surface 31.
[0014]
According to the present embodiment, the skin parting line 1a of the skin 1 described above extends linearly or curvedly on both the near side and the back in the direction perpendicular to the paper surface of FIG. Therefore, the reference mold surface portion 31c of the mold surface 31 also extends along the skin parting line 1a on both the near side and the back in the direction perpendicular to the paper surface of FIG. Similarly, the assist plug 7 also extends along the skin parting line 1a in the form of a plate on both the front side and the back side in the direction perpendicular to the paper surface of FIG.
[0015]
The assist plug 7 can be moved in the directions of arrows Y1 and Y2 by an actuator. The upper end portion 7f of the assist plug 7 functions as an engaged portion that fits into the concave reference mold surface portion 31c.
When the skin 1 is attached, the skin 1 is held on the clamper 2 as can be understood from FIG. Further, the position of the skin parting line 1a of the skin 1 is opposed to the upper end portion 7f of the assist plug 7 and the reference mold surface portion 31c of the molding die 3, and the three are aligned. Next, the heating device 78 is moved in the direction of arrow B1 between the skin 1 and the mold 3, and the skin 1 is heated to an appropriate temperature by the heating device 78.
[0016]
Next, as shown in FIG. 1 (B), the assist plug 7 is moved in the direction of the arrow Y1, the skin parting line 1a of the skin 1 is lifted by the assist plug 7, and the upper end 7f of the assist plug 7 is recessed with the concave reference mold surface. It fits into the part 31c. As a result, the skin parting line 1a of the skin 1 is pressed against and held by the reference mold surface portion 31c of the mold 3, thereby restraining the skin parting line 1a. At this time, as can be understood from FIG. 1B, the skin 1 has a mountain shape in which the skin parting line 1a becomes the apex Pn.
[0017]
According to the present embodiment, the reference mold surface portion 31c of the molding die 3 has a concave shape corresponding to the upper end portion 7f of the assist plug 7. Therefore, as can be understood from FIG. Fits well to the surface portion 31c. Therefore, the skin parting line 1a of the skin 1 can be reliably restrained.
In this way, with the assist plug 7 holding the skin parting line 1 a of the skin 1 on the reference mold surface portion 31 c of the mold 3, the clamper 2 is moved upward, that is, in the direction of the arrow Y 1 to move the skin 1 to the mold surface of the mold 3. Approach 31. At this time, the suction device 38 is operated, and the skin 1 is adsorbed to the base material 4 by the suction action from the suction hole 32, so that the skin 1 is shaped. This is because the base material 4 has air permeability. As a result, the skin 1 is integrally attached to the lower surface of the substrate 4, and a resin molded product having the skin 1 is obtained.
[0018]
Thereafter, the resin molded product is released from the mold surface 31 of the mold 3.
As described above, according to this embodiment, prior to attaching the skin 1 to the base material 4, the skin parting line 1 a of the skin 1 is held on the reference mold surface portion 31 c of the mold 3 by the assist plug 7. to bound. And after restraining, the skin 1 is stuck to the whole base material 4 by the suction action by the suction hole 32.
[0019]
According to the present embodiment, the skin parting line 1a of the skin 1 is held and restrained by the reference mold surface portion 31c of the mold 3 before the entire skin 1 is attached. 1a can be accurately positioned with high accuracy. Therefore, it is possible to prevent the positional deviation of the skin parting line 1a, and it is advantageous to obtain a high-quality resin molded product.
According to the present embodiment, the upper end portion 7 f of the assist plug 7 is fitted into the convex reference mold surface portion 31 c of the mold 3 when positioning the skin 1. Thus, the fitting of the concave and convex can contribute to further suppressing the positional deviation of the positioned skin parting line 1a.

Further, when the skin 1 is heated by the heating device 78, the skin 1 is softened with the heating, and the dripping phenomenon of the skin 1, that is, the drawdown is likely to occur. Excessive drawdown of the skin 1 is not preferable because it may cause a positional shift of the skin parting line 1a. In this respect, according to the present embodiment, as can be understood from FIG. 1B, the assist plug 7 is arranged on the lower side of the skin 1, and the skin 1 to be drawn down can be supported from the lower side by the assist plug 7. . Therefore, it is advantageous in suppressing the draw down of the skin 1 and thus reducing and avoiding the positional shift of the skin close-out line 1a caused by the draw down.
[0021]
Further, when the protruding convex portion 30 is formed on the mold surface 31 of the mold 3, the skin 1 is likely to come into contact with the convex portion 30 during the shaping of the skin 1. In this case, the skin 1 may be unnecessarily stretched and the skin parting line 1a of the skin 1 may be displaced from a fixed position. In this respect, according to this embodiment, before the skin 1 is adhered to the entire base material 4, that is, before the skin 1 touches and extends the convex portion 30 of the mold 3, the skin parting line of the skin 1. Since 1a is held on the reference mold surface portion 31c of the mold 3 by the assist plug 7, it is advantageous in reducing and avoiding unnecessary stretching caused by the contact between the convex portion 30 of the mold 3 and the skin 1. In this sense as well, it is advantageous for reducing and avoiding the positional deviation of the skin parting line 1a.

[0024]
An air drive cylinder 83 is provided on the back side of the second split mold 35. When the drive cylinder 83 is operated, the cylinder rod 83c is extended, and the assist plug 7 is moved forward in the direction of the arrow Y2. When the drive cylinder 83 reversely moves, the cylinder rod 83c contracts and the assist plug 7 moves backward in the arrow Y1 direction. The drive cylinder 83 moves the assist plug 7 forward and backward as described above, and functions as a plug drive means. The drive cylinder 83 is an air type, but may be a hydraulic type.
[0025]
As can be understood from FIG. 2A when attaching the skin 1, the skin 1 is fixed to the first split mold 34 by the skin fixing tool 1 h, and the mold surface 34 i of the first split mold 34 is covered with the skin 1. . This skin 1 has a skin parting line 1a as described above. Next, the second split mold 35 is lowered together with the assist plug 7 in the direction of the arrow Y2 that is the mold clamping direction. 2B, the engaged recess 7r of the assist plug 7 is fitted into the convex reference mold surface portion 31c of the first split mold 34. Therefore, the skin parting line 1 a of the skin 1 is pressed and held by the reference mold surface portion 31 c of the mold surface 31 of the mold 3. At this time, as can be understood from FIG. 2B, the convex portion 30 of the second split mold 35 is not in contact with the skin 1, and therefore, unnecessary stretching due to the contact with the convex portion 30 does not occur in the skin 1. .
[0026]
The mold clamping movement of the second split mold 35 is stopped in the state shown in FIG. In this state, the suction device 38 is operated to suck the skin 1 from the suction hole 32 of the first split mold 34. Therefore, as shown in FIG. 2C, the skin 1 is attached to the mold surface 34 i of the first split mold 34. Accordingly, the skin 1 is shaped into a shape along the mold surface 34 i of the first split mold 34.
Next, as shown in FIG. 2D, the second split mold 35 is lowered in the arrow Y2 direction, and the second split mold 35 and the first split mold 34 are clamped. In this state, the resin raw material P is injected into the cavity 36 from the resin injection hole 35n, and the resin raw material P is foamed and solidified. Then, the foaming molded product with which the skin 1 was stuck together is obtained.
[0027]
According to this embodiment, the engaged recess 7r of the assist plug 7 is fitted to the convex reference mold surface portion 31c, so that the skin parting line 1a of the skin 1 can be reliably held. Therefore, even when the resin molding pressure is high, it is advantageous to suppress the positional deviation of the skin parting line 1a.

Therefore, when the resin raw material P is injected from the resin injection hole 35n, it is advantageous to apply the injection pressure in the direction in which the skin 1 is brought into close contact with the mold surface 34i of the first split mold 34. Therefore, it is advantageous for shaping the skin 1 along the mold surface 34 i of the first split mold 34.
[0028]
When the resin raw material P is foamed and solidified in the cavity 36 as described above, it is necessary to reverse the drive cylinder 83 to move the assist plug 7 upward, that is, in the direction of the arrow Y1, and retract from the cavity 36. This is because if the assist plug 7 is not retracted from the cavity 36, a cavity corresponding to the tip of the assist plug 7 is generated in the resin molded product. The assist plug 7 needs to be retracted before the resin material P in the cavity 36 is completely solidified. Therefore, in general, the assist plug 7 is retracted from the cavity 36 before the resin material P is injected.
[0029]
