Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a foam molding mold for a foam integral with skin material, and more specifically, it is provided with a lower mold and an upper mold, and a skin material is applied to the lower mold. The present invention relates to a foam molding mold for a foam integral with a skin material, in which a stock solution of a foamed synthetic resin is injected into the inside of the skin material, and the foam is foam-molded integrally with the skin material.

[Conventional technology]

BACKGROUND OF THE INVENTION Conventionally, integral foamed skin materials have been used for seat cushions, seat backs, headrests, etc. of vehicles. The foaming mold for this integrally foamed skin material includes a lower mold and an upper mold that is fitted to the lower mold, and is designed such that it can be used by inserting a core mold.

With the skin material placed in the lower mold, a core mold is inserted into the lower mold to form a hollowed out part of the foam, reducing the amount of foamed synthetic resin undiluted solution, and also forming a sheet. A frame such as a frame or a headrest frame is inserted and a foam is molded integrally with the skin material and the frame.

In the conventional skin material of integral skin foam, the skin material is formed in a shape corresponding to the part covering the surface side of the molded product, for example, the main part and the side part, and the back side is formed in an open state. After the foamed synthetic resin stock solution was injected through the open part to form a molded product, the back side of the molded product was covered with a back cover part or the like.

[Problem to be solved by the invention]

However, in conventional skin-integrated foams, the open part on the back side of the molded product, that is, the back side of the skin material, must be covered with a back cover, etc., but when the open part is made large, the back cover The problem is that the back cover becomes larger and the appearance deteriorates, and it is difficult to install the back cover completely separate from the skin, and if the back cover is connected to the skin in advance, the foam This had the disadvantage that foam molding was difficult.

It is an object of the present invention to enable the skin material to be disposed on the lower mold with one end of the back cover part connected to the skin material, to form the back cover part small by forming the open part small, and to provide foaming. To provide foam molding of a skin material-integrated foam in which the back cover part does not get in the way when pouring a resin stock solution and the open part of the skin material can be simply and quickly covered by the back cover part after molding the foam. It is.

[Means to solve the problem]

The present invention was made in view of the above-mentioned problems,
An integrated skin material comprising a lower mold and an upper mold, a skin material is disposed on the lower mold, and a stock solution of a foamed synthetic resin is injected into the inside of the skin material to form a foam integrally with the skin material. In the foam molding mold for the foam, one end of the back cover part is connected to the skin material, a storage part that is sealed by mold matching with the upper mold is formed on the outside of the side of the lower mold, and the storage part is The device is characterized in that the back cover portion is housed.

[Effect]

According to the present invention, a storage portion that is sealed by mold matching with the upper mold is formed on the outside of the side of the lower mold, and the back cover is connected to the skin material while the skin material is disposed on the lower mold. By storing the part in the storage part and matching the upper mold to the lower mold, the storage part is sealed, and there is no risk that the back cover part stored in the storage part will be impregnated with the foamed synthetic resin stock solution, and the foaming After the body is molded, the open back part of the skin material can be easily and quickly covered by the back cover part.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a foam molding mold for an integrally foamed skin material according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 and FIG. 3 each schematically show an embodiment of a foam molding mold for an integrally foamed skin material according to the present invention, and this embodiment will be described as being applied to a seat bag. This foaming mold 11 includes a lower mold 12 and an upper mold 13 that is matched with the lower mold 12.
A core mold 14 is inserted between the lower mold 12 and the upper mold 13. Lower mold 12, upper mold 13 and core mold 1 of foam mold 11
4 can use an aluminum mold or a sheet metal mold.

In this embodiment, the tip 14a of the core mold 14 is continuous with the hole forming protrusion 16 formed on the side 15 of the lower mold 12, and the tip 14a of the core mold 14 and the protrusion are connected to each other. The head rest stay is inserted into the space formed in the foam body 35 by the portion 16.

An outer wall 17 is formed on the side portion 15 of the lower mold 12 so as to protrude outward from the lower end of the side, and to protrude upward from the position where it extends outward. A storage section 18 is formed by the inside. The upper open part 19 of this storage part 18 is designed to be sealed when the upper mold 13 is fitted.

FIG. 2 schematically shows an embodiment of the skin material applied to the present invention, and this skin material 22 has an open part 23 formed on the back side, which corresponds to the upper part of the back side of this skin material 22. One end 24a of the back cover portion 24 is connected to the position where the rear cover portion 24 is connected. Further, fasteners 25a and 25b are formed on the outer circumferential edge 23a of the open part 23 of the skin material 22 and the outer circumferential edge 24b of the back cover 24, respectively, and by closing these fasteners 25a and 25b, the back cover part 24 is attached to the open part 23.
It is designed so that it can be installed and covered. Note that the rear cover portion 24 can be attached by an appropriate connecting means instead of the fasteners 25a and 25b.

The skin material 22 disposed on the lower mold 12 consists of a front skin 22a and a wadding 22b joined to the back side of the skin 22a, and the back cover portion 24 is formed from a single synthetic resin sheet. However, the back cover part 24 can be
It may be made of the same material as.

As shown in FIG. 1, a skin material 22 is provided on the lower mold 12, and a back cover portion 24 is connected to the skin material 22.
is stored in the storage part 18 from the upper end of the side part 15 of the lower mold 12. Although the back cover portion 24 is stored in a rolled-up state, it may be stored in a folded state. Next, the core mold 14 is attached to the lower mold 12. Further, if necessary, a seat frame or the like can be inserted and integrally formed.

Next, the upper mold 13 is mold-aligned with the lower mold 12, the upper open part 19 of the storage section 18 is sealed with one end 31 of the upper mold 13, and the foamed synthetic resin is poured through the injection port 32 formed in the upper mold 13. Inject the stock solution of
As shown in the figure, the foam 3 is integrated with the skin material 22.
form 5.

Next, the lower mold 12 and the upper mold 13 are opened, the core mold 14 is removed, and the skin integral foam 21 is inserted into the lower mold 1.
2, and attach the back cover part 24 to the back open part 23 of the skin material 12 with fasteners 25a and 25b.
By attaching this, it is possible to obtain a skin integral foam body 21 with the back open portion 23 covered. In the above-mentioned embodiment, the core mold 14 is used, but this may be omitted.

〔Effect of the invention〕

The above is the configuration of one embodiment of the foam molding mold for the integrally foamed skin material according to the present invention. According to this configuration, the outer side of the lower mold is sealed by mold matching with the upper mold. A storage part is formed in which the back cover part, one end of which is connected to the skin material, can be stored in the storage part, so that the back cover part does not get in the way when pouring the stock solution of foamed synthetic resin. After molding the foam, the open back part of the skin material can be covered easily and quickly with the back cover part, and work efficiency can be significantly improved.
