Abstract

PURPOSE:To enable automatization of the application of a skin material to a plastic molding material, by providing a supporting frame for supporting said plastic molding material, a mold over which said skin material is stretched and to which said plastic molding material is pressed, and a frame driving means for moving said supporting frame to press said plastic molding material against said skin material. CONSTITUTION:A frame driving means 20 is driven to move a supporting frame 11 successively to the side of a mold 15, and consequently a plastic molding material 12 is pressed against a skin material 16. At this time, since the skin material 16 is positioned between the mold 15 and the plastic molding material 12, it is flexibly deformed along a contour of the plastic molding material 12. Then, the supporting frame 11 is further moved to the side of the mold 15, so that the plastic molding material 12 is pressed into the mold 15 to be tightly adhered with the skin material 16. At this time, the pressing force of the plastic molding material 12 against the skin material 16 is set relatively large within an elastic range of the plastic molding material 12 in consideration of the shape and structure of the material 12. Accordingly, the skin material 16 can be pressed against the plastic molding material 12 sufficiently in the range not breaking the material 12.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a plastic molding method for attaching a skin material along the contour surface of a plastic molding material having an external contour that has been previously molded into a desired shape. The present invention relates to a method and apparatus for applying a skin material to a material.

[Prior Art] Generally, a skin material is attached to a plastic molded body formed by molding a plastic material such as FRP into a desired shape so as to follow the outer contour of the body and adhere closely to the contour surface. There are some that consist of When producing such a plastic molded article, if a skin material 3 is attached in advance to a plastic material 2 such as a flat plate having a flat material surface 1 before molding, and then molding can be performed, As shown in FIG. 4, the skin material 3 can be mechanically attached to the surface 1 of the plastic material 2 using a roll 4 or the like. On the other hand, if the molding process requires heat treatment or the like and the skin material 3 cannot be attached to the plastic material 1 in advance before the molding process, as shown in FIG. A skin material 3 is manually attached to the plastic molded material 5 along its contoured surface 6.

[Problems to be Solved by the Invention] By the way, it is extremely complicated and requires skill to manually attach the skin material 3 to the plastic molded material 5 formed with a desired external contour that is not flat. It is desired to devise a method and apparatus that can mechanically carry out such a pasting operation of the skin material 3.

As a technology related to this, a "method for manufacturing interior materials" (Japanese Patent Publication No. 62-559694. Publication) has been proposed, but this proposal involves press-molding the facing material onto the interior base material. It is thought that a relatively large deforming force acts on the facing material, resulting in a noticeable change in the wall thickness of the facing material in areas where it is difficult to form, for example, convex portions of the interior base material.

[Means and effects for solving the problem] The first invention provides a method for attaching a deformable skin material to a plastic molded material having a molded external contour along the contour surface. The plastic molded material is pressed against the skin material with a pressing force within its elastic range, and the pasting work is performed by pressing the plastic molding material against the skin material.

A second invention is an apparatus for attaching a deformable skin material to a plastic molded material having a molded external contour along the contour surface, which includes a support frame that supports the plastic molded material, and a support frame that supports the plastic molded material, and a skin material that is stretched over the plastic molded material. a mold onto which the plastic molded material is pressed; and frame driving means for moving the support frame forward and backward into the mold to press the plastic molding material against the skin material; This allows the plastic molded material supported by the support frame to be attached by machine to the skin material stretched over the mold.

[Embodiment] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

First, the pasting device will be described.

As shown in FIGS. 1 and 2, 11 is a support frame, and this support frame 11 has a plastic molded material 1.
A slide rail 13 for removably supporting 2 is provided. The plastic molded material 12 is configured such that a flange 17 formed thereon is inserted into the slide rail 13 and attached to and supported by the support frame 11. The plastic molded material 12 is formed by pre-molding a plastic material to have a desired external contour.

On the other hand, the plastic molded material 12 of this support frame 11
A base 14 is disposed at a position opposite to the support side of the base 1.4, and a concave or convex mold 15 against which the plastic molded material 12 is pressed is formed on the base 1.4. A skin material 16 is provided between the mold 15 of the base 14 and the plastic molded material 12 supported by the support frame 11 so as to extend toward the base 14 side. This skin material 16 is configured to be deformable along the contour surface 18 of the plastic molding 12, and is configured to be deformable along the contour surface 18 of the plastic molding 12.
Bonding means such as adhesive is applied to the attachment surface 19 facing 8.

The support frame 11 is attached to the base 14 configured in this way.
A frame driving hand a20 such as a hydraulic cylinder is provided which expands and contracts to move the support frame 11 toward the mold 15 in the vertical direction and press the plastic molded body 12 against the skin material 16 on the mold 15.

The base 14 is also provided with guide rods 21 extending along the forward and backward direction of the frame driving means 20, and these guide rods 21 are inserted into holes 22 formed in the support frame 11 to support the frame. It is designed to guide the forward and backward movement of the frame 11.

With this configuration, the plastic molded material 12 supported by the support frame 11 can be pressed against the skin material 16 stretched over the mold 15 and attached by a mechanical operation.

Next, a pasting method will be explained based on the above-mentioned device.

First, the plastic molded material 12 having the molded external contour is mounted on the support frame 11, and the skin material 16 is stretched between the mold 15 of the base 14 and the supported plastic molded material 12.

Next, the frame driving means 20 is driven to advance the support frame 11 sequentially toward the mold 15 side, and press the plastic molding material 12 against the skin material 16. At this time, the skin material 16 is pressed against the mold 15 and the plastic molding material 12. , and deforms flexibly along the contoured surface 18 of the plastic molding 12.

Thereafter, the support frame 11 is further moved toward the mold 15 side, and the plastic molding material 12 is pushed into the mold 15 and brought into close contact with the mold 15. At this time, the force with which the plastic molded material 12 is pushed into the mold 15 and pressed against the skin material 16 is set to a relatively large force within the elastic range due to the shape and structure of the plastic molded material 12. Thereby, the plastic molded material 12 can be sufficiently pressed against the skin material 16, as shown in FIG. 3, without destroying it.

Note that the pressing force can be achieved by controlling the frame driving means 20 based on the value obtained in a test using a test piece or the like.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects are achieved.

(1) The plastic molding material is applied to the skin material by pressing it against the skin material with a pressing force within its elastic range, which prevents the material from stretching significantly or changing the wall thickness as in the past. Pasting work can be done by machine while keeping the pressure down. Q) A support frame that supports the plastic molding material, a mold to which the skin material is stretched and the plastic molding material is pressed, and a frame driving means that advances and retreats the support frame from the mold to press the plastic molding material against the skin material. By having the structure equipped with this, it is possible to mechanize the pasting work.
