し、押え８ｄで金型を押圧する。 When placing the mold 3 on the top surface of the surface plate 1 and fixing the mold 3 with the clamp device 2, first fit the lever 13 into the mounting holes 6d-1 and 6e-1 of the cam shaft member 6. , rotate the lever 13 counterclockwise. With this operation, the cam shaft member 6 rotates counterclockwise, the push rod 7 also rotates, and the protrusion inserted into the elongated hole 8f of the clamp piece 8 rotates and comes into contact with the inner wall of the elongated hole of the clamp piece 8. Move the clamp piece 8 forward inward. At this time, since the cam portion 6a has a flat surface 6a-3, a small diameter outer circumferential surface 6a-1, and a flat surface 6a-4, the clamp piece 8 moves horizontally forward by a distance l, and the protrusion 8c at the inner end
protrudes from the inner end opening of the case 4 and is located on the upper surface of the presser foot of the mold 3. When the push rod 7 is rotated approximately 75 degrees to the position shown by the dashed line in FIG. The plane 6d-5 is the plane 6a-4.
By projecting in a more tapered shape, the clamp piece 8 is pushed upward. Therefore, the clamp piece 8 is tilted counterclockwise about the bolt 9, the inner protrusion 8c is lowered, and the presser foot 8d presses the upper surface of the mold 3 and is rotated to the surface plate 1. At this time,
The push rod 7 moves from the one-dot chain line position to the two-dot chain line position about 30 minutes.
It is inserted into the groove 5d-2 of the bearing member 5, and when it reaches the bottom of the groove, the flat surface 6a-5 of the cam part 6
The apex of the clamp piece 8 comes into contact with the clamp piece 8, pushes the clamp piece 8 up to the maximum, and is stopped and held in this state. At this time, the clamp piece 8 has a tapered notch 8i on the bottom surface, a notch 8e-1 on the top surface of the protrusion 8e, and a notch 10a on the bottom surface of the spacer 10. It tilts smoothly and presses the mold with the presser foot 8d.

をケース４′内へ挿入が容易となる利点を有する。 The present invention is not limited to the above embodiment, but may be constructed as shown in the second embodiment shown in FIGS. 5 and 6. In the second embodiment, the engagement relationship between the bearing member 5' and the holding member 11' is changed, and no protrusion is formed on the bottom surface of the bearing member 5' housed in the case 4'. Instead, bolt holes 5'h are drilled at the four corners, and similarly, bolt holes 4' are drilled at the same positions in the bottom wall 4'a of the case 4'.
h is drilled. On the other hand, a spacer 20 is newly provided to be interposed between the lower surface of the bottom wall of the case 4' and the holding member 11' fixed to the surface plate 1, and a bolt hole 20a is bored in the spacer 20. After storing the bearing member 11' in the case 4', the spacer 20 is attached by screwing the bolt 21 from the spacer 20 into the bearing member 11' through the bottom wall of the case. A recess 20b is formed on the lower surface of the spacer 20, and the holding member 1
A convex portion 11'c protruding from the upper surface of the case 4' is engaged with the bearing member 1' to hold the case 4' and the bearing member 5' so that they cannot be moved back and forth. Note that other configurations and operations are the same as those of the first embodiment, so the same reference numerals are given and explanations will be omitted. With the configuration of the second embodiment, the bearing member 5'

野に適用できるものである。Effects As is clear from the above explanation, according to the mold clamping device according to the present invention, by manually rotating one camshaft member using a lever, the clamp piece stored in the case can be moved from the case to the mold clamping device. The mold can be advanced upward and then the clamp piece can be tilted to press the mold. The structure is simple, and unlike conventional pressure sources such as hydraulic pressure is not used, so costs can be reduced. What's more, by simply rotating a lever, the mold can be fixed with a pressing force comparable to that of hydraulic pressure. In addition, since the clamp piece is housed in the case, it does not get in the way when the mold is placed on the surface plate, and it has various advantages such as requiring less space for the clamp device. Note that the present invention is not limited to the examples,
The present invention can be applied to various fields without departing from the gist of the invention.
