て、取出ヘッドの軽量化を挙げることができる。In recent years, improvements in injection molding machines, molds, resin materials, and the like have made it possible to reduce the molding cycle time, particularly when molding thin objects such as floppy disks, to within 10 seconds per cycle. ing. For this reason, there is a demand for a high-speed resin molded product take-out machine,
One of means for achieving a high speed of the resin molded product take-out machine is to reduce the weight of the take-out head.

This is also done in the conventional resin molded product take-out head. That is, instead of the steel plate fork-shaped substrate 100, a honeycomb structure core made of aramid paper is formed,
A fork-shaped substrate 100 having a three-layer structure in which aluminum plates are arranged on both sides of the core portion is used, or a reinforced plastic fork-shaped substrate 100 reinforced with carbon fibers is used.

And a plurality of suction pipes 107 or a plurality of suction pads 101 for fixing the plurality of intake / exhaust pipes 102 to the back side of the substrate 100 and the plurality of intake / exhaust pipes 102 are independently connected to each other. It is necessary to use a plurality of pipe joints (not shown) and the like, and the weight of the take-out head becomes heavy corresponding to the total weight of the joints and hinders the reduction of the weight. .

2, the manifold 103, the pipe retainer 107, and the like protrude. Accordingly, the thickness T of the take-out head is equal to the thickness t1 of the fork-shaped substrate 100, the amount of protrusion t of the intake / exhaust pipe 102, the manifold 103, the pipe retainer 107, and the like.
It becomes the sum of 2 and becomes extremely large. For this reason, it is necessary to set a large opening / closing stroke amount of the mold of the injection molding machine, and the molding cycle time of the injection molding machine becomes longer, which prevents the cycle time from being shortened and causes a reduction in molding efficiency. ing.

である。That is, in the conventional head for taking out a resin molded product, the heavy weight impedes high-speed movement, and the thick thickness requires a large opening / closing stroke of the mold. However, the removal time of the molded product and the molding cycle time are prolonged, thereby preventing the improvement of the molding efficiency. Therefore, the present invention enables high-speed movement by weight reduction, contributes to shortening the time for taking out a molded product, and reduces the thickness to shorten the molding cycle time by the molding machine and improve the molding efficiency. It is an object of the present invention to provide a take-out head for a resin molded product that can be obtained.

てもよい。In the above embodiment, the take-out head of the resin molded product in which the substrate 1 is formed in a fork shape is explained, but the shape of the substrate 1 is not limited to the fork shape, and the suction pad is used. Any shape can be selected based on the number of the suction pads 2, 2 ... And the layout of the suction pads 2, 2 ... And the number of the suction pads 2, 2. Also,
A description will be given with a configuration in which the main passage 12A is formed by a groove having a semicircular cross section formed on the bonding surface 8 side of the core portion 10 of the back side light weight plate body 6 with the front side light weight plate body 5. However, the main passage 12A may be formed by a groove having a rectangular cross section, and is formed on the bonding surface 8 side of the core portion 10 of the back side lightweight plate body 6 with the front side lightweight plate body 5. A semi-circular groove symmetrical with the semi-circular groove is formed on the bonding surface 7 side of the core portion 10 of the front side lightweight plate body 5 with the back side lightweight plate body 6.
A main passage 12A having a circular cross section in which both are abutted or a main passage 12A having a square cross section in which square grooves are abutted may be adopted.

This can contribute to the speeding up of the resin molded product take-out machine, and also reduce the thickness of the take-out head. The molding cycle time can be shortened and the molding efficiency can be improved. Further, in the invention according to the second aspect, the weight reduction can be achieved by the foamed resin, and the necessary strength can be secured by the covering portion made of the reinforced plastic. Further, since the unintended air leakage caused by the air permeability of the foamed resin can be reliably prevented by the non-air permeability of the covering portion, the suction of the resin molded product by the suction pad during the operation of the intake / exhaust means. And adsorption release can be performed appropriately.
