Abstract

PURPOSE:To obtain a car mat molding tool which can set up felt to a fixed position of the molding tool in place of a vacuum sucking method, by a method wherein a clamping device to be operated by an air cylinder is fitted to openings each possessed by a top force in a recessed part into which the felt is set up and the felt is clamped and held by its tip. CONSTITUTION:Car mat raw fabric 1 and felt 3 are press-molded and a car mat is molded by making use of a bottom force 2 possessing a projected part 21 on which the heated car mat raw fabric 1 is put and a top force 4 possessing a recessed part 41 to which a felt 3 to be laminated onto the car mat raw fabric 1 is set up. At the time of setting the felt 3 into the recessed part 41 of the top force 4, when the felt 3 is put on the projected part 11 of a bottom force 2 and the top force and bottom force are mold-registered, the felt 3 is clamped by the tip of a clamp device from an opening 42 and held in the recessed part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car mat molding die and a molding method using the same.

[0002]

2. Description of the Related Art A vacuum suction method is used as a method of setting a material to be molded in a molding die (for example, JP-A-2-28).
6315, JP-A-5-8290).

[0003]

However, when the material to be molded is an air permeable material such as felt, the vacuum suction method may cause a mistake in setting the felt, and the amount of sucked air increases. However, there is a problem in that electricity costs are high and work noise is high. Therefore, it is an object of the present invention to provide a car mat forming die and a forming method capable of setting the felt at a predetermined place of the forming die instead of the vacuum suction method.

[0004]

According to the present invention, there are provided a lower mold having a convex portion on which a heated carmat original fabric is placed, and an upper mold having a concave portion on which a felt to be laminated on the carmat original fabric is set. A carmat molding die for press-molding the above-mentioned carmat original fabric and the felt by using the above-mentioned upper die having a plurality of openings in a recess in which the felt is set, and each opening is operated by an air cylinder. There is a carmat molding die to which a clamp device is attached and which is configured to clamp and hold the felt at its tip and a molding method using the same.

[0005]

According to the above-mentioned forming die, the lower die having the convex portion on which the heated carmat original fabric is placed, and the upper die having the concave portion on which the felt laminated on the original carmat original fabric is set In press-molding the carmat original fabric and the felt by using, the felt is placed on the lower mold, and a plurality of recesses formed in the upper mold when the upper mold is matched with the lower mold. Since the felt is clamped by the tip of the clamp device from the opening of the device and held in the recess, there is no mistake in felt setting, and since the operation of the clamp device is performed by the air cylinder, the operating cost is low and there is no noise. It is preferable that the clamp device can be retracted and retracted from the opening, and the air cylinder is used to retract and retract the clamp means because the felt can be clamped securely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to specific examples shown in the accompanying drawings. FIG. 1 shows steps of a molding method according to the present invention, in which a lower mold 2 having a convex portion 21 on which a heated carmat original fabric 1 is placed, and a felt 3 laminated on the carmat original fabric 1 are set. Upper mold 4 having a recess 41
Using the above, the carmat original fabric 1 and the felt 3 are press-molded to form a carmat.

Here, the carmat original fabric 1 has a flocked layer 12 formed on one side of a resin backing material 11, while the felt 3 is usually a non-woven fabric having a thickness of about 7 mm.

When setting the felt 3 in the recess 41 of the upper mold 4, the felt 3 is placed on the convex part 11 of the lower mold 1 (see FIG. 1 (a)), and the upper mold 4 is placed. The felt 3 is clamped by the tip 52a of the clamp device 5 through a plurality of openings 42 formed in the recess 41 of the upper mold 4 when the lower mold 1 and the lower mold 1 are held together (see FIG. 1 ( See b)).

More specifically, as shown in FIG. 2, the clamp device 5 has an air cylinder 51 in the upper part and a pair of clamp claws 52a, 5 in the lower part with a mounting flange 53 interposed therebetween.
Clamping means 52 provided with 2a is provided via a case 54, the clamping means 52 is fitted into the opening 42 of the recess 41 of the upper die 4 from the outside, and the mounting flange 53 is fixed to the upper die 4 by screwing ( (Figure 3).

The air cylinder 51 has an air supply pipe 51.
While the a and the intake pipe 51b are connected, as shown in FIG. 3, the clamp claws 52a and 52a of the clamp means 52 are oppositely attached to the tip of the cylinder rod 51c of the air cylinder 51 in a constricted manner. Since it is guided in the downward constricting direction from the guide hole 54a at the lower end of the air cylinder 51, when the air cylinder 51 is supplied with air, the clamp claw 52a of the clamp means 52 is guided through the cylinder rod 51c.
When projected from a, the pair of clamp claws 52a come into contact with the upper surface of the felt 3 placed on the convex portion 21 of the lower mold 2 so that the felt 3 is sandwiched by the pair of clamp claws 52a and 52a, and the felt 3 is lifted up. It is set in the recess 41 of the mold 4.

Then, the mold is opened in this state, the upper mold 4 is separated from the lower mold 2 (see FIG. 1 (c)), and the heated carmat original fabric is placed between the upper and lower molds (see FIG. 1 (d). )), And remolding, and press-molding the above carmat original fabric and felt.

FIG. 4 shows a modification of the clamp means 52.
Here, the pair of clamp claws 52a, 52 shown in FIG.
Instead of sandwiching and holding the felt 3 by a, the tips of the four piano wires 52b are bent into a hook shape, and when the tips are projected, the tips are focused on the center, abut on the surface of the felt 3, and are slightly pulled up. It is configured to sandwich. Since other parts are the same as those in FIG. 2, the same members are designated by the same reference numerals and the description thereof will be omitted.
