It is necessary to accurately position the mold in place. However, if the chuck of the automatic machine is independently positioned with high accuracy, the cost of the apparatus becomes very high.

[0004]

The device of the present invention has been devised to solve such a problem, and the gist thereof is to hold a metal fitting that has been made to stand by at a standby position and to fix the metal fitting. A device for setting a molding die for a fitting-equipped molded product at a predetermined position, comprising: (a) a support member for supporting the fitting in a positioning state at the standby position; and (b) the support member and the molding die, respectively. Positioning recesses provided, (c) a chuck that holds and releases the metal fitting, (d) a chuck support body that supports the chuck, and (e) a position of the metal fitting on the support member with respect to the chuck. A positioning recess and a positioning pin provided on the chuck support in a positional relationship corresponding to the positional relationship between the metal fitting set position in the molding die and the positioning recess; and (f) a holding body that holds the chuck support.
(G) A fitting hole provided on one side of the holding body and the chuck support and a fitting hole that is abutted against the other and loosely fits into the fitting hole with a certain gap, and is horizontally aligned by the gap. A posture restraint member that is relatively movable and that holds the periphery of the fitting hole from both front and back sides to restrain the chuck support body in a horizontal posture, and a posture restraining member interposed between the holding body and the chuck support body. A floating mechanism having a return rubber for returning the support body to the neutral position, and (h) a transfer means for moving the chuck between the metal fitting standby position and the metal fitting set position for the mold. .

[0005]

In the device of the present invention, when the metal fitting in the standby position is held by the chuck, the chuck is positioned based on the fitting of the positioning pin and the positioning recess. Similarly, when the metal fitting held is set at a predetermined position of the molding die, the setting position of the metal fitting by the chuck is determined based on the fitting between the positioning pin and the positioning recess of the molding die.

Since the chuck is held in a floating state with respect to the holding body holding the chuck via the chuck support and is capable of relatively moving a minute distance, the holding body can be moved with high accuracy. Even without positioning, the metal fitting can be accurately held by the chuck and can be set at a predetermined position of the molding die.

According to the present invention, the metal fitting can be accurately set at a predetermined position of the upper mold holding the metal fitting securely, and the chuck is positioned under the guidance of the mold and the supporting member. Therefore, the device can be constructed at a lower cost than when the chuck is accurately positioned by the metal fitting setting device alone.
