Abstract

An apparatus for producing a multilayer molded article including a resin body and at least one sheet of a skin material, an edge part of which is present in a surface area of the resin body. The apparatus includes a mold, and a clamping device for clamping an edge part of a skin material or mated edge parts of adjacent skin materials during molding.

Claims

1. A mold for producing a multilayer molded article comprising a resin body and at least one skin material, an edge part of which is present in a surface area of the resin body, said mold comprising:

a single male mold;

a single female mold; and

clamping means which is separable from said male and female molds and placed in a molding face of said male mold for clamping an edge part of a skin material or piled edge parts of adjacent skin materials;

wherein one of said male and female molds is provided with receiving means for receiving said clamping means.

2. A mold for producing a multilayer molded article comprising a resin body and at least one skin material, an edge part of which is present in a surface area of the resin body, said mold comprising:

a male mold;

a female mold;

clamping means for clamping an edge part of a skin material or piled edge parts of adjacent skin materials; and

a clamping frame for holding a periphery of the skin material.

3. A mold for producing a multilayer molded article, which comprises:

a male mold;

a female mold opposing said male mold; and

clamping means for holding an edge part of a skin material;

wherein one of said male and female molds is provided with an engaging groove for receiving said clamping means.

4. The mold according to claim 3, wherein said clamping means has a receiving opening for receiving and securing an edge part of a skin material, said receiving opening including pins disposed across said opening for securing an edge part of a skin material.

5. The mold according to claim 4, wherein said receiving opening is a groove having alternating wide and narrow portions, said wide portions being sufficient to allow resin melt to pass therethrough.

11. The mold according to claim 3, further including a clamping frame surrounding said male mold for holding a periphery of the skin material.

12. The mold according to claim 11, wherein said clamping frame is displaceable with respect to said male mold.

6. A mold assembly for producing a multilayer molded article, said mold assembly comprising:

a male mold;

a female mold opposing said male mold; and

clamping means for holding an edge part of a skin material;

wherein said male mold is provided with an engaging groove for receiving said clamping means.

7. The mold assembly according to claim 6, wherein said clamping means has a receiving opening for receiving and securing an edge part of a skin material, said receiving opening including pins disposed across said opening for securing an edge part of a skin material.

8. The mold assembly according to claim 7, wherein said receiving opening is a groove having alternating wide and narrow portions, said wide portions being sufficient to allow resin melt to pass therethrough.

9. The mold assembly according to claim 6, further including a clamping frame surrounding said male mold for holding a periphery of the skin material.

10. The mold assembly according to claim 9, wherein said clamping frame is displaceable with respect to said male mold.
