BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded product take-out machine, and more particularly to a movable frame of a molded product take-out machine in which a movable frame is formed of a synthetic resin body containing a reinforcing fiber.

[0002]

The movable frame of a molded product take-out machine that takes out a molded product obtained by injection molding by a molding machine from a mold and releases it on a table or a conveyor uses an aluminum extruded material. We tried to reduce the weight and shorten the take-out time, but to further reduce the weight,
For example, it was necessary to use a reinforced fiber-containing synthetic resin body containing reinforced fibers such as carbon fiber, boron resin, glass fiber and titanium fiber.

[0003] However, in these reinforced fiber-containing synthetic resin bodies, in order to screw various members such as rails and sensors, screws cannot be directly tapped as in the case of an aluminum extruded material. To stop it, it was necessary to provide a screw receiver inside. For this reason, in order to attach other members, it takes time and effort to work, and an increase in weight cannot be avoided due to the screw receiver used.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks. The object of the present invention is to reduce the weight while maintaining the strength, and to reduce the weight when attaching other members. Screws can be screwed directly,
An object of the present invention is to provide a movable frame of a molded product take-out machine capable of improving the efficiency of the mounting operation.

[0005]

According to the present invention, a chuck member which is attached to a fixing plate of a molding machine and holds a molded product is provided with a chucking direction of the molding machine, a direction orthogonal to the molding direction, and a vertical direction. In a molded product removal machine that moves in at least a two-dimensional direction and removes a molded product from the molding machine, the movable frame that moves the chuck member in the predetermined direction is formed from a reinforced fiber-containing synthetic resin body provided with a metal plate on an intermediate layer. It is characterized by becoming.
