Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a mold for interior materials. To explain in more detail, a skin material is placed in the lower mold, and a base material is formed inside the skin material. The present invention relates to a mold for an interior material in which a synthetic resin material is injected and a base material is molded integrally with the skin material in a state where an upper mold is fitted to a lower mold.

[Conventional technology]

BACKGROUND ART Conventionally, as shown in FIGS. 3 and 4, an interior material 1 in which a base material 3 is integrally formed with a skin material 2 has been known. This interior material 1 is used for door trims, molded ceilings, and other interior materials of vehicles, etc., and the surface material 2
The terminal 2a is folded back to the base material 3 side and the terminal is processed.

The skin material 2 consists of a skin 4 made of a cloth material or a synthetic resin sheet on the front side, and a cushioning material 5 made of foam such as slab urethane or coarse hair bonded to the back side of the skin 4. It is formed.

As shown in FIG.
The a side is folded inward at the end of the back surface side of the base material 3 to be molded to form a folded part 2b, and this folded part 2b is further bent upward at the inner end of the presser mold 9, and the upper mold 8 and The inner edge of the presser mold 9 and the skin material 2
The terminal 2a side of the terminal 2a is held between the terminals 2a and 2a.
Then, a synthetic resin material 3a such as a resin solution such as hard polyurethane or a stock solution of foamed synthetic resin is injected into the inside of the skin material 2 of the lower mold 7 to form a base material 3 integrally joined to the skin material 2. being done.

[The problem that the idea aims to solve]

However, the terminal 2 of the skin material 2 of the conventional interior material 1
The a side is folded back inward at the back end of the base material 3 to be molded to form a folded part 2b, and this folded part 2b hangs down to the lower mold 7 side to securely hold the skin material 2 in a predetermined position. However, it has the disadvantage that it cannot be positioned and disposed easily and quickly, and the appearance of the end of the skin material cannot be improved.

The purpose of the present invention is to provide a mold for interior material that can improve the appearance of the end of the skin material, allow easy and quick positioning and placement of the skin material, and improve molding work efficiency. It is something to do.

[Means to solve the problem]

The present invention was developed in view of the above-mentioned problems, and consists of placing a skin material on a lower mold, injecting a synthetic resin material that can be used as a base material into the inside of the skin material, and molding an upper mold onto the lower mold. In a mold for an interior material that molds a base material integrally with the skin material in a state in which the lower mold is formed as a vacuum molding mold, and a hollow presser mold is removably attached to the upper end of the lower mold, The presser mold is configured to fold back and hold the end side of the skin material together with the upper mold, and the presser mold is formed as a vacuum forming mold.

[Effect]

According to the mold for interior materials of the present invention, a hollow presser mold for folding and holding the end side of the skin material is detachably attached to the upper end of the lower mold, and the presser mold is formed as a vacuum molding mold. Therefore, the end side of the skin material can be easily and quickly and reliably folded back and held by the lower die and the presser die, and furthermore, the end side of the skin material can be held between the upper die and the presser die. .

〔Example〕

FIGS. 1 and 2 each schematically show an embodiment of a mold for an interior material according to the present invention, and the lower mold 12 of this mold 11 is formed as a vacuum mold. Reference numeral 13 is a vacuum hole, and 14 is a vacuum device connected to the vacuum hole 13.

A presser mold 16 is detachably attached to the upper end of the lower mold 12 to hold the end 21a of the skin material 21 by folding it inward so as to cover the end 26a of the base material 26 to be molded. End 21a of the skin material 21 extending inward from the folded portion 21b
is bent further backwards at the inner end of the presser die 16 and is held between the upper die 17 and the presser die 16. A protrusion 16a is provided at the lower end of the presser die 16.
is formed, and this protrusion 16a is adapted to engage with the engagement hole 12a of the lower die 12.

Note that the lower mold 12 and the presser mold 16 are not limited to those that are attached by engaging the engagement hole 12a and the protrusion 16a, but may be positioned using a dowel pin or the like.

The skin material 21 includes a skin 22 made of a cloth material or a synthetic resin sheet on the front side, and a foam such as slab urethane, or coarse hair and chips bonded to the back side of the skin 22, as shown in the prior art. The cushioning material 23 is made of urethane, a mixture thereof, or the like.

A presser mold 16 that is detachably attached to the lower mold 12
is formed in a hollow shape, and a vacuum hole 16b is formed at a position where the end 12a of the skin material 12 is sandwiched between the upper die 17 and the upper die 17. Further, the lower mold 12 and the presser mold 16 are communicated with each other through a communication hole 18, and the vacuum device 1 of the lower mold 12
4 is activated, the hollow part 16c of the presser die 16
is maintained in a vacuum state. In addition, lower mold 12 and presser mold 1
A gasket 19 is attached to the contact surface of 6.

Next, as shown in FIG.
Attach the skin material 21 to the lower die 12 and the holding die 16.
The vacuum device 14 of the lower mold 12 is operated to bring the skin material 21 into close contact with the lower mold 12 and the presser mold 16 which is communicated with the lower mold 12 through the communication hole 18. At this time, the terminal 21 of the skin material 21 is
A is bent inward to form a folded portion 21b. Then, as shown in FIG. 1, the upper mold 1
Match 7.

Next, a synthetic resin material, such as a hard urethane resin solution or a undiluted solution of foamed urethane, for molding the base material 26 is injected into the skin material 21 of the lower mold 12 through an injection port formed in the upper mold 17. A base material 26 is formed integrally with the base material 26.

The interior material 20, which is a molded product consisting of the skin material 21 and the base material 26, is taken out from the mold 11, and the skin material 21
By cutting the terminal 21a at the cut portion of the folded portion 21b, the interior material 20 as a product is produced.
can be obtained.

[Effect of idea]

The above is the configuration of one embodiment of the mold for the interior material according to the present invention. According to this configuration, the hollow presser mold that holds the end side of the upper end skin material of the lower mold by folding it back can be detached and attached. Since the holding die is formed as a vacuum forming die, the end side of the skin material can be easily and quickly and reliably folded back and held by the lower mold and the holding die, and there is no risk that the folded part of the covering material may sag. It is possible to obtain a mold for an interior material that can produce an interior material with an excellent appearance that is free of wrinkles and wrinkles.
