のテーパを有している。 The mold base plate 1 is composed of two parts 1A and 1B with different thicknesses with the surface flush with each other.
A mold guide 12 having an inverted L-shaped cross section is fixedly protruding from the surface edge of B in a direction perpendicular to the central axis in the longitudinal direction. Further, a guide groove 1b cut out along the central axis is bored in the bottom surface of the portion 1B, and the guide groove forms an opening 1a that opens to the outer surface of the base plate in a certain range close to the thin-walled portion 1A. A shaft 3 which is fixed at a predetermined position on both walls is provided perpendicular to the central axis, and a fixing pawl 2 is rotatably attached to the shaft 3. A fixed claw operating cam (hereinafter referred to as operating cam) 4 is slidably provided along the guide groove 1b, and the end opening of the thick portion 1B of the guide groove is closed from the outside with a cover plate 7, and the operating cam 4 and A spring 6 is provided between the cover plate 7 and the operating cam as a pressing tool that always urges the operating cam toward the thin wall portion. In the figure, 5 is the bottom plate of the guide groove 1b. An L-shaped fixed claw operation lever (hereinafter referred to as the operation lever) 11, whose one end is pivotally connected to the base plate 1 with a pin 10, is rotatably provided on the lower surface of the thin section 1A. A link 8 connecting one end of the operating cam 4 is pivotally connected to the operating lever 11 and the operating cam 4 through pins 8a and 9, respectively, thereby forming a toggle link mechanism. 5 and 6 are partially enlarged sectional views showing the functions of the fixed claw 2 and the operating cam 4. The fixed claw 2, which is pivoted on the shaft 3, has a mold gripping part 2c on the upper part, and a mold gripping part 2c when the mold is released. It has a lower release projection 2b that engages with the tapered projection 4c of the operating cam 4, and a tapered surface 2a that wedges against the tapered surface of the tapered projection 4c of the operating cam 4 when the mold is fixed. The operating cam 4 has a tapered protrusion 4c that engages with the release protrusion 2b of the fixed claw 2 when the mold is released to rotate and overturn the fixed claw, and the upper surface of the fixed claw 2 that has been rolled over is flush with the surface of the base plate 1. Concave portion 4a that is accommodated so that
, the above-mentioned tapered protrusion 4c that engages with the tapered surface 2a of the fixing claw when the mold is fixed, and a recessed part 4b that accommodates the release protrusion 2b of the fixing claw when the mold is fixed, and is wedged with the tapered surface 2a of the fixing claw. The upper surface of the tapered projection 4c has a taper in the range of approximately 3° to 10°, similar to the tapered surface 2a.

なるように第６図の状態となる。 When fixing the mold from the released state, first support one side of the mold H with the mold guide 12, and then move the mold operating lever 11 shown in FIG.
0 as an axis, the operating cam 4 moves along the guide groove 1b in the direction of arrow s in FIG. 5 via the link 8, and the tapered protrusion 4c of the operating cam is fixed as shown in FIG. It engages with the tip of the tapered surface 2a of the claw 2, rotates the fixed claw 2 clockwise (in the direction of arrow t in Fig. 5) about the shaft 3, and moves the fixed claw from the horizontal position to the upright state. The mold gripping portion 2c of the fixed claw grips the mold and stops. In this case, the release protrusion of the fixed claw fits into the concave portion 4b of the operating cam and does not interfere with rotation. Also, since the operating cam is urged in the direction of the arrow s by the spring 6, the tapered surface 2a of the fixed claw and the tapered surface of the tapered projection 4c of the operating cam are firmly wedged, and the fixing claw is firmly fixed to the mold. do. To release the mold from the fixed state shown in Fig. 5, rotate the operating lever 11 in Fig. 3 in the direction of the arrow u, and the operating cam will slide in the direction of the arrow v in Fig. 6. The tapered protrusion 4c of the fixed claw engages with the release protrusion 2b of the fixed claw, and the fixed claw is moved counterclockwise (sixth
(in the direction of arrow w in the figure), the fixing claw is displaced from the upright state to the rolled-over state, and is fitted into the concave portion 4a of the operating cam so that the tip of the fixing claw is flush with the surface of the base plate 1. The state shown in FIG. 6 is reached.
