CONSTITUTION:A skin sticking mold is constituted by providing a recessed part 17 having a size permitting the insertion and bending of a finger at the position between the outer periphery of the molding part of a mold and a skin trimming groove 16 and filling the recessed part 17 with an elastomer compressible by a finger.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin adhesive molding die for manufacturing an automobile interior product by adhesively molding a resin skin material on the upper surface of a preformed air-permeable base material.

[0002]

2. Description of the Related Art Conventionally, as a method for producing a molded article W in which a resin skin material 2 is adhered to the upper surface of a breathable base material 1 having a desired curved surface shape as shown in FIG. Figure 2
As shown in FIG. 5, the base material 1 coated with the adhesive on the upper surface is fitted to the mold surface of the molding die 10 equipped with a vacuum suction mechanism (including the hollow chamber 11, the suction blower 12, the through pores 13 and the like) and at a predetermined temperature. The heat-softened skin material 2 is adhered and adhered along the curved surface shape of the base material 1, and then the upper mold 15 having the trimming blade 14 is lowered to lower the trimming blade 14
Is inserted into the skin trimming groove 16 provided in the molding die 10 to trim the outer periphery of the skin material 2 to raise the upper die 15, and then the molded product W is manually formed from the molding die 10 (the base material 1 and the skin material). 2) is attached) and the work is finished.

However, the operation of taking out the molded product is carried out by peeling the molded product W from the molding die 10, but it is difficult to peel it because the fingertips do not easily enter between the molded product W and the upper surface of the molding die 10. In particular, when there is an undercut U in a part of the molded product W as shown in FIG. 1 and FIG. 2, it becomes more difficult to peel off and there is a problem that it takes time to take out the molded product W. The present invention has been made in view of the above problems, and an object of the present invention is to provide a skin pressure-sensitive adhesive molding die capable of easily peeling a molded product from the molding die.

[0004]

In order to achieve the above object, a skin pressure-sensitive adhesive molding die according to the present invention is a skin pressure-sensitive adhesive molding die having a vacuum suction mechanism and having a skin trimming groove provided on the outer periphery of a mold molding portion. One or more recesses having a size that allows insertion and bending of fingers are provided at an arbitrary position between the outer periphery of the die-molded portion and the skin trimming groove, and an elastic body that can be compressed by pressing with fingers is provided in the recess. It is characterized in that the upper surface is embedded so as to match the upper surface of the mold.

[0005]

According to the present invention, by adopting the above-mentioned means for solving, the peeling work after trimming the outer periphery of the skin material adhesively molded on the upper surface of the substrate is carried out by the operator buried in the concave portion of the molding die. The elastic body is pressed and compressed with a fingertip and bent inward so that a part of the peripheral edge of the molded product is engaged with the fingertip in a hooked state so that the molded product can be easily peeled off from the molding die and taken out. become.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. Since the basic structure of the molding die 10 has the same structure as that described as the conventional example based on FIG. 2, it is omitted and will be described with reference to FIGS. 3 to 6 which are plan views of the molding die 10. Arbitrary position between the outer periphery of the die-molded portion and the skin trimming groove 16 (position where the operator M can reach)
Recesses 17.17 are provided at two locations (one location may be used if the shape of the mold is simple and the molded product is easily peeled off). The concave portion 17 has a size such that the finger F of the operator M can be inserted and bent, and the concave portion 17 has a neoprene rubber or a sponge rubber 18 as an elastic body that can be compressed by pressing the fingertip. Is adhered only on the bottom surface of the mold, and its upper surface is aligned with the mold surface. (See FIGS. 4 and 5) As an elastic body, as shown in FIG. 6, a coil spring 20 having a receiving plate 19 attached to the upper end may be embedded. In this case, the structure becomes more complicated than that of the neoprene rubber matahah sponge rubber 18, but the abrasion and scratch damage due to the fingertips are reduced.

As shown in FIG. 2, the thus constructed member is applied onto the molding die 10 by applying an adhesive to the air-permeable base material 1 which is preformed on the upper portion of the molding die 10. Next, while operating the vacuum suction mechanism (hollow chamber 11, suction blower 12, through-pore 13) of the molding die 130-150.
A resin-made skin material 2 which has been softened by heating to 0 ° C. is placed along the upper part of the base material 1 and contact molding is performed by vacuum suction to bond the base material 1 and the skin material 2. Next, the upper die 15 is lowered, the trimming blade 14 is inserted into the skin trimming groove 16 to cut (trim) the skin material 2, and the upper die 15 is lifted, and then the skin not adhered to the base material 1 Figure 3 after removing the wood chips
Will be in the state of. Next, the operator M presses the two places where the neoprene rubber or sponge rubber 18 which is an elastic body exists with the fingers F from above the skin material 2 to compress it (the state of FIG. 5) and bends the fingertips inward. Then, a fingertip is hooked on a part of the peripheral edge of the molded product W to engage it, and then both hands are pulled up to peel the molded product W from the molding die 10 and take it out.

[0008]

As is apparent from the above description, the present invention provides a concave portion having a size such that a finger can be inserted and bent, at a position between the outer periphery of the molding portion of the molding die and the skin trimming groove.
Since an elastic body that can be compressed by finger pressing is embedded in this recess, the molded product with the skin material trimmed can be peeled from the mold by engaging the fingertip with a part of the peripheral edge of the molded product in a hooked state. As a result, the molded product can be easily peeled off by this lifting, and the time required for taking out the molded product can be greatly shortened.
