B zone and C zone mold cooling devices 30, 3
A resin coating device 50 is provided on the outer side of each of the rollers 0 and 0, respectively.

As shown in FIGS. 1 to 6, when the movable table 40 on which the mold 13 is assembled is moved onto the mold cooling devices 30, 30 in the B zone or C zone, the resin coating device 50 moves over the movable table 40. The mold 13 moves in and out in the direction of the arrow in the figure toward the A zone.
This is a device for applying resin 14 on top.

In the resin coating device 50, a supply port 56 into which the resin 14 is introduced from the resin supply pipe 52 is provided at the top of the resin tank 53, and a plurality of nozzles 54 for coating the resin 14 onto the mold 13 are provided at the bottom of the resin tank 53. is formed. These nozzles 54 are opened and closed by electromagnetic valves 55.

is applied onto the mold 13 by natural fall.

In addition, inside this resin tank 53, for example, 2-octylhexyl phthalate or n-octyl phthalate is added to vinyl chloride resin as a plasticizer.
Contains plastisol mixed with ~35% and made into a sol.

The amount of resin 14 applied is adjusted by a solenoid valve 55 attached to the lower part of the resin tank 53.

Along with this resin coating device 50, deaerators 60, 60 are provided above and above the mold cooling devices 30, 30 in the B zone and C zone.

The deaerators 60, 60 apply the resin 14 coated onto the mold 13 by the resin coating device 50 to the mold 1.
3. A large number of tapered small holes 10 are bored in the mold 13 to form anti-slip protrusions for automobile mats.
It is necessary to fill the inside with resin 14.

As shown in FIGS. 1 to 6, in the deaerators 60, 60 for the B zone and C zone, the support stand 17 is placed so that the box-shaped vacuum pad 61 covers the upper surface of the mold 13.

The vacuum pad 61 also comes into contact with the assembly frame 18 of the mold 13 of the movable table 40, and has a rubber pad 64 affixed to its lower peripheral edge. A plurality of air suction ports 66 are formed in the upper part of the vacuum pad 61. One end of a hose 65 is attached to the air suction port 66 of the vacuum pad 61, and the other end of the hose 65 is connected to a vacuum pump (not shown).

After the resin 14 is applied onto the mold 13 by the resin coating device 50, the vacuum pad 61 of the deaerator 60 is lowered by the operation of the lifting cylinder 62, and applied to the assembly frame 18 of the mold 13. They are coming into close contact with each other.

Furthermore, the air inside the vacuum pad 61 is removed by a vacuum pump (not shown), and the mold 13 and resin 14 are removed.
Air bubbles existing between the two are removed, and the small tapered hole 10 provided in the mold 13 is also reliably filled with the resin 14. Therefore, small anti-slip protrusions on the back side of the automobile mat can be reliably formed, and cracks in the synthetic resin 14 on the back side of the fiber mat 12, which were caused by air bubbles, can be formed. This prevents the film from peeling off.

The A zone and the B zone are provided with a fiber mat supply device that moves in and out of the mold heating device and presses the fiber mat onto the resin of the moving table that is moved with the resin coated on the mold heating device. ing.

After coating the inside of the mold 13 with the resin 14 and then filling the inside of the mold 13 with the resin 14 using the same degassing devices 60 and 60 in the B zone or C zone, the movable table 4
One mold 13 of the movable table 40 coated with the resin 14 is placed on the mold heating device 20 in the A zone, and the mold is heated at a predetermined temperature for a predetermined time by the mold heating device 20. The fiber mat 12 is pressed onto the upper surface of the resin 14 which has been semi-gelled by heating the resin 13.

In this fiber mat supply device 70, the support stand 1
The shaft of the horizontally moving cylinder 72 arranged on the side of 7 is connected to the fiber mat mounting table 71, and as the horizontally moving cylinder 72 expands and contracts, the fiber mat mounting table 71 is connected to the heating device 20 in the A zone and the heating device 20 in the B zone. It is designed to reciprocate over the cooling device 30. In this embodiment, the fiber mat mounting table 71 is normally located on the A zone, and the fiber mat mounting table 71 is located on the A zone.
It moves to the B zone only when it is supplied onto the resin 14. The fiber mat 12 is placed on the fiber mat mounting table 71 with the base fabric 16 protruding from the side. A pressing cylinder 74 is attached to one end of this fiber mat mounting table 71. A pressing roller 73 extending parallel to the widthwise sides of the fiber mat 12 is rotatably supported on the shaft of the pressing cylinder 74.

On the other hand, a clamping cylinder 75 is installed parallel to the pressing cylinder 74 and above the support base 17 in the A zone. A dogleg-shaped clamping claw 76 is attached to the shaft of the clamping cylinder 75, and the clamping claw 76 is attached to the edge of the movable table 40 while sandwiching the base fabric 16 of the fiber mat 12. It comes into contact with the plate 77 and fixes the fiber mat 12.

And a movable table 40 coated with resin 14
When one of the molds 13 is on the A zone, the fiber mat 12 on the fiber mat mounting table 71 on the A zone
The base cloth 16 is sandwiched and fixed between the clamping claws 76 attached to the clamping cylinder 75 when the clamping cylinder 75 is lowered and the clamping plate 77 of the movable table 40. At the same time, the pressure roller 73 is lowered by the extension of the pressure cylinder 74, and presses the base fabric 16 of the fiber mat 12.

Thereafter, the shaft of the horizontal movement cylinder 72 is retracted, and the fiber mat mounting table 71 and the pressing roller 73 are horizontally moved in the direction of the B zone. Along with this movement, the fiber mat 12 with one end of the base fabric 16 fixed on the moving table 40 is pulled down onto the resin 14 of the mold 13, and the pressing roller 73 presses this fiber mat 12 to make it horizontal. It's starting to move. In this way, the fiber mat 12 is pressed onto the semi-gelled resin 14 by the pressing roller 73, and the resin 14 is completely welded and integrated with the back surface of the fiber mat 12 without any gaps.

After the semi-gelled resin 14 and the fiber mat 12 are welded and integrated by the fiber mat supply device 70, the resin 14 is further heated by the mold heating device 20 in order to completely gel it. It's summery. After being sufficiently heated, the movable table 40 is moved onto the cooling device 30 in the B zone, the mold 13 is cooled, and the resin 14 changes into a rubber-like gel state by cooling. After cooling for a predetermined period of time, the fiber mat 12 is removed from the mold 13.

In addition, in the automobile mat bucking device 11 of the present invention, each of the above-mentioned devices can be operated separately. For example, in zone B, the resin 14 is applied onto one of the molds 13 on the moving table 40 by the resin coating device 50 and the deaerator 60.
At the same time, in the A zone, the resin 14 on the other mold 13 on the movable table 40 is semi-gelled by the mold heating device 20, and the resin 14 is filled into the mold 13 with the resin 14. The fiber mat supply device 70 supplies the fiber mat 12, and the heating device 20 further heats the resin 14 for a predetermined period of time. Then, one mold 13 of the moving table 40 is moved to the A zone, and the other mold 13 of the moving table 40 is moved to the A zone.
