Claims

[Scope of utility model registration request]

A molding device is a molding device in which a cavity is formed between two facing mold bodies and a molded product is molded within the cavity, and one mold body side has a cylinder part, the cylinder part and the above-mentioned mold body. A passage communicating with the cavity is formed, and a piston is provided in the internal space of the cylinder portion so that it can move forward and backward within the same space, and a piston is provided at the tip of the piston with a diameter that is approximately the same as that of the passage. A closing pin that can move forward and backward through the passage as the piston moves forward and backward protrudes, and air introduction passages that individually feed compressed air communicate with the front and rear portions of the piston in the internal space of the cylinder portion. When air is introduced from the rear air introduction path, the piston moves forward, and the closing pin closes the opening on the passage side of the cavity, and when air is introduced from the front air introduction path, the piston moves forward. When the piston moves backward and the closing pin moves backward within the passage, the inside of the passage communicates with the internal space of the cylinder part, and the molded product inside the cavity is taken out by the pressure of the introduced air. A mold device for molding, characterized in that it is adapted to be used for molding.
