Abstract

PURPOSE:To enhance the speed of the separation and removal operation of a sprue and a runner and a molding by a structure wherein an insertingly holding hole part, which is equipped with an suction-exhaust ports for removal of sprue and runner, is attached to receiving pocket parts for removal of the molding. CONSTITUTION:An arm 9 is advanced toward a movable mold 5 so as to respectively bring a receiving pocket part 12 for removal of a molding and an insertingly holding hole part 13 for removal of a sprue and a runner close to the molding W and the sprue S, which are adhered to the movable mold 5, in order to insert the tip part of the sprue S in the insertingly holding hole part 13. Air is sucked from air passages 16 and 17 under the state just mentioned above and at the same time the molding W and the sprue S are ejected with ejector mechanism provided on the movable mold 5. As a result, the sprue S and the molding W are separated from each other, resulting in holding the sprue S in the insertingly holding hole part 13 and the molding W in the receiving pocket parts 12 by suction. The sprue S and the moldings W are blown off so as to be discharged to the predetermined positions.

In this state, the air passage 16 is opened by the air suction or supply device.
.. When air is sucked through 17 and the molded product W and sprue S are ejected by an ejector mechanism provided in the movable mold 5, since the mold 5 is a submarine gate mold, the protrusion of the sprue S closes the gate. The sprue S and the molded product W are separated, and the sprue S and the molded product W are ejected and released from the mold 5. Since the sprue S is sucked by air, the sprue S is inserted into the holding hole. 13 and is held under suction. Although the molded product W is located very close to the sprue S, it is simultaneously stored in the storage pocket 12 and held under suction without being obstructed by the sprue S, and in this state, the photoelectric sensor 15 detects when the molded product W is stored. is confirmed.

After receiving a detection signal from the photoelectric sensor 15, the arm 9 is moved back toward the stationary mold 3 by the slide rail 10 in the After retracting from between 3.5 and 5, air is supplied to the insertion holding hole 13 side at the position where the sprue/runner is discharged, and air is supplied to the storage pocket section 12 side at the position where the molded product W is discharged. Since the sprue S is pushed out from the insertion hole portion 13 by air pressure, and the molded product W is blown away from the storage pocket portion 12 by air, the molded product W and the sprue runner are separately discharged to a predetermined position.

(Effects of the Invention) As described above, the present invention allows the sprue attached to the movable mold to be ejected by the ejector mechanism, inserted into the insertion holding hole by air suction, held by suction, and conversely discharged by air blowing. At the same time, the molded product can be ejected by the ejector mechanism, stored and held in the storage pocket by air suction, and conversely ejected by air blowing. The molded product can be held and discharged quickly and reliably. Moreover, since the insertion and holding hole is used to hold and eject the sprue, the above operations can be carried out even if the molded product is located very close to the sprue. In addition, since the storage pocket section is used to hold and eject molded products, there are fewer restrictions due to the shape of the molded product, and depending on the shape of the molded product, there is no need to replace the molded product adsorption section one by one, and the molded product is not damaged. It becomes difficult to attach. Therefore, a simple device can support high cycle molding and diversification of molded product shapes.
