JPS5936866B2 - Molding method for automotive floor mats - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an automobile floor mat to be laid in a vehicle interior.

Conventionally, in order to form floor mats, necessary parts of the mat material are suspended using springs, clamps, etc. in a separate process, or one end of the mat material is pulled by hand during pressure molding to prevent wrinkles, misalignment, etc. This prevented cracks, etc.

Additionally, for the purpose of saving labor, relatively shallow shapes were molded by supporting the mat material with pins in the mold. The present invention aims to solve the above-mentioned conventional drawbacks,
To provide a method for molding a floor mat for an automobile, which can prevent wrinkles, tears, etc. even when molding a floor mat with deep and shallow shapes, and can eliminate the above-mentioned defects with a simple structure.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a cross section of the mold and the mat material before starting molding, and 1 is the mat material, which is heated to an appropriate temperature at the time of starting molding.

Reference numeral 2 denotes an upper mold, on the outer end of which a grip upper 4 with a lever retainer 3 fixed is attached so as to be adjustable up and down with an adjusting screw 5.

At one end of the lower molding mold 6 which presses the mat material 1 between the upper molding mold 2 and the upper molding mold 2, a lower grip 7 to which a lifting spring 12 is biased downward is provided in a guide member 13. A lever 8 is rotatably attached to the upper end of 7 with a pin 9, and when the upper mold 2 is lowered, the lever holder 3
A claw 11 is provided on the upper surface of the right end so that the right end moves upward and thrusts into the mat material 1, and a spring 10 is elastically loaded at the end.

The operation will be explained below with reference to each figure, and the same parts are given the same reference numerals.

First, as shown in FIG. 1, a heated mat material 1 is inserted between an upper mold 2 and a lower mold 6.

The mat material 1 is heated in a previous step using a method suitable for the material, such as a heater, hot air, or steam, but a heater may be provided inside both or one of the upper mold 2 and the lower mold 6. Next, lower the upper mold 2 (or raise the lower mold 6)
When the lever holder 3 comes into contact with the left end of the lever 8 and pinches one end of the mat material 1, as shown in FIG. To prevent the mat material 1 from shifting inside the mold.

As shown in Figure 3, when the upper mold 2 is lowered,
The lifting spring 12 of the lower grip 7 is compressed, and the lever holder 3 and the lever 8 descend while holding the mat material 1, and the lifting spring causes the mat material 1 to slip onto the upper and lower molds 2 and 6. 12 is increased in proportion to the spring force.

Next, as shown in Fig. 4, when the upper mold 2 is further lowered,
The mat material 1 is gripped by the upper grip 4 attached to the upper mold 2 and the lower grip 7 of the lower mold 6, and the mat material 1 is prevented from slipping into the upper mold 2 and the lower mold 6 by holding them down. The mold matching is completed with the mat material 1 slightly stretched, and the molding of the mat material 1 is completed.

After the mat molding is completed, the upper mold 2 is raised and returned to the state shown in Fig. 1, but at the same time, the lower mold 6 is moved laterally, the next mat material is placed on it, and it is moved to the bottom of the upper mold 2. However, if the molding upper mold 2 is lowered to move on to the next molding, the mat material 1 can be easily inserted and the efficiency will be improved.

When the floor mat molding method of the present invention is adopted, in the conventional molding method, only the first presser is used, and when the mat is deeply shaped, tears occur in the mat, and if the presser foot is weakened, wrinkles occur. However, by the molding method of the present invention, primary,
By setting the secondary presser foot, cuts, wrinkles, etc. are eliminated,
You can get beautiful finished floor mats.
