[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide type locking mechanism of a die for molding a corner portion of a weather strip or a glass run.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. In the figure, 9 is the front side, 10 is the left side, and 11 is the right side. The conventional slide-type locking mechanism of the mold that molds the corners of weather strips, grass runs, etc. has a thick plate that is long in one direction viewed from the left and right sides, and the rear side that hits the mold 1 is set to the rear height. The pokayoke plate 12 that is inclined and scraped off is formed by forming a groove 13 on the end surface of the lid mold 1a and an inclined groove 14 on the front end surface of the slide mold 1b so as to partially fill the groove 13 of the lid mold 1a. The slide mold 1b is pressed and locked by fitting the slide mold 1b and then fixing it with the bolt 15.

However, in this slide type lock mechanism, first, the Pokayoke plate 12 is manufactured in accordance with the mold 1.
In accordance with the shape (width / inclination) of the pokayoke plate 12, the end faces of the lid mold 1a and the slide mold 1b of the mold 1 are carved to form grooves 13 and inclined grooves 14, and the lid mold 1a is screwed with screws. Manufacturing and processing such as processing holes is complicated, and the Pokayoke plate 12 becomes long due to the thickness of the lid mold 1a, which causes a problem in strength. Moreover, once attached, rattling caused by wear and scraping・ There is a problem that the gap cannot be adjusted.

[0004]

The problem to be solved is that the slide type locking mechanism has various problems in manufacturing / processing, strength, rattling and clearance adjustment.

[0005]

SUMMARY OF THE INVENTION The present invention is a slide type 1
A lock mechanism for a slide mold 1b of a mold 1 including a pair of Pokayoke plates 2 and 2 for adjusting the position of b, each pokayoke plate 2 being formed in an L shape when viewed from the side, and A long slot 6 is formed in the horizontal portion 2a for inserting the bolt 3 in the horizontal direction, and the inner surface of the vertical portion 2b is tapered so as to be inclined with respect to the vertical surface. A screw hole 5 for mounting the bolt 3 is opened, and a small rotating disk 4 that abuts on the inner surface of the vertical portion 2b is pivotally supported on each side surface of the slide mold 1b.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to FIGS. 1 to 3. Reference numeral 1 is a mold for molding a corner portion or the like of a workpiece 9 such as a weather strip or a glass run, 1c is a lower mold, 1d, 1e is a medium type and 1a is a lid type. A screw hole 5 is formed in the horizontal direction on each side surface of the lid die 1a near the one end surface. Reference numeral 1b is a slide type for adjusting rattling and clearance, and 2 is a Pokayoke plate attached to each side surface close to one end surface of the lid type 1a. By arranging them in the horizontal direction, a long slot 6 is formed in the horizontal direction through which the bolts 3 attached to the screw holes 5 of the lid mold 1a are inserted, and the vertical portion 2b is tapered so that the inner surface is inclined with respect to the vertical surface when viewed from the side. There is. Further, a small rotating disk 4 such as a ball bearing is rotatably supported on the side surface of the slide die 1b, and the vertical portion 2 of the Pokayoke plate 2 is attached to the small rotating disk 4.
The inner surface of b is brought into contact.

Explaining the operation, the lid mold 1a is prepared in advance.
The Pokayoke plate 2 is attached to each side surface of the with the bolts 3, and the lid mold 1a and the slide mold 1b are assembled. At that time, if there is looseness or gaps in the slide mold 1b, loosen the bolts 3,
A small rotating disk 4 is attached to the inclined inner surface of the vertical portion 2b of the Pokayoke plate 2.
The vertical portion 2b is pressed against the mold 1 side through a small rotating disc 4 which can be freely rotated and is brought into contact with the circumference of the mold, thereby adjusting the rattling and the gap. After the adjustment is completed, the bolt 3 is firmly tightened to fix the Pokayoke plate 2 to the lid mold 1a.

[0008]

[Effect of the Invention] Since the present invention is configured as described above,
It has a simple structure and is easy to manufacture and process, and it is possible to easily adjust the rattling and gap of the slide mold 1b through the small rotating disk 4. Moreover, the pokayoke plate 2 is formed in an L shape. , And each side is fixed with two bolts 3, so there is no problem in strength. In addition, by using the Pokayoke plate 2 as a standard component, it can be exchanged and used for any mold.
