Many inventions and ideas have already been made for automatic mold attachment and detachment, but in order to automatically attach and detach molds, in conventional equipment, multiple cylinders are fixed to a base plate on which the molds are attached, and pistons inserted into the cylinders are moved. A claw is provided at the tip, and the mold is attached to and removed from the base plate by reciprocating the piston. In this device, the position where the mold is normally gripped by the claws has to be extended forward of the cylinder when the mold becomes smaller. In this case, the distance that the claws protrude from the cylinder increases, making the force for gripping the mold unstable, which is not preferable. The present invention is a device for eliminating such drawbacks,
Next, it will be explained according to the drawings. 1 is a mold clamping device of an injection molding machine, 2 is a mold clamping cylinder fixed to a base, and 2a is a flange of the mold clamping cylinder 2. 3
is a fixed plate, which is fixed to each end of four upright stays 4 with nuts 5.
6 is a movable plate that can be moved along the stay 4;
A ram 7 is inserted into the mold clamping cylinder 2, and its tip is fixed to the movable platen 6. 8 is a heating cylinder that plasticizes and injects the resin. A plurality of holding frames 9 are fixed to the fixed platen 3 and the movable platen 6 at positions where the molds can be gripped, respectively. Reference numeral 10 denotes a mold removable piece that moves forward and backward within the frame of the holding frame 9. The tip 10a is wedge-shaped, and the mounting plates 11a and 12a of the fixed mold 11 and the movable mold 12 are connected to the fixed platen 3, respectively. It is crimped onto the movable platen 6. Reference numeral 13 denotes a cylinder provided in the mold removal/detachment piece 10, and in this embodiment, one mold removal/detachment piece 10 is provided with two cylinders. 14 is a piston inserted into the cylinder 13, and the end of the piston rod 14a is fixed to the rear end beam 9a of the holding frame 9 with a nut 15. 1
Reference numeral 6 denotes a T-shaped groove provided on the fixed platen 3 and the movable platen 6, respectively, and 17 is a T-shaped bracket fixed to the bottom of the mold detachable piece 10, and the T-shaped bracket 17 is fitted into the T-shaped groove 16. Then, the mold detachable piece 10 is moved. 18 is a backward limit switch fixed to the upper part of the holding frame 9, 19 is a forward limit switch, 20 is a cam for the backward limit switch, and 21 is a cam for the forward limit switch. Next, the operation will be explained. The mold clamping cylinder 2 is driven to lower the movable platen 6 and open the mold. Oil is injected into the oil hole 10c of the cylinder 13 provided in the mold removable piece 10, and the mold is placed on the movable platen 6 with the mold removable piece 10 retracted, and then the movable platen 6 is raised. The mold is held between the fixed platen 3 and the movable platen 6, oil is injected into the oil hole 10b, the mold detachable piece 10 is advanced, and the tip part 10a is attached to the fixed side mounting plate 1.
1a and the movable mold mounting plate 12a, and the fixed mold 11 and the movable mold 12 are respectively attached to the fixed plate 3.
and fix the movable plate 6. When taking out the mold, the movable platen 6 is raised to close the mold and the mold removable piece 10 is moved back, and the mold mounting plate 11a of the mold removable piece 10 is
Release the crimp 12a. In the present invention, when the mold detachable piece 10 moves forward and the forward limit limit 19 is excited, a signal indicating that the mold detachable piece 10 has tightened the mold is emitted, and the mold detachable piece 10 moves back and reaches the backward limit. When the limit switch 18 is energized, a signal indicating that the mold removable piece has retreated is emitted, confirming that the mold has been removable from the fixed platen 3 and the movable platen 6. As described above, in the present invention, the mold removable pieces 10 are connected to the fixed platen 3, respectively.
Since the movable platen 6 is fitted into the T-shaped groove 16 of the movable platen 6, the force for gripping the mold does not change regardless of the forward position, and the mold can be crimped.
