Abstract
A molding device for easily releasing a molding material produced by transferring a minute shape to resin using a die having the minute shape formed thereon from the die with no damage. A method for controlling such molding device is also provided. The molding device and the control method are characterized in that the force for releasing the molding material from the die is detected and an alarm signal is delivered if the number of times when the releasing force becomes higher than a level preset depending on the molding material reaches a preset number of times.
Claims12
A method for controlling a molding device comprising:
- transferring a shape of a die having a minute shape onto a molding material by bringing the die into contact with the molding material and applying pressure thereto;
- releasing the molding material from the die sequentially from one edge to another edge of a transfer part on the molding material, the transfer part being a part onto which the shape of the die has been transferred;
- detecting a mold releasing force in the mold releasing step;
- and
- outputting an alarm signal if a number of times the mold releasing force becomes equal to or higher than a mold releasing force value preset in conformity to the molding material has reached a preset number of times.
A molding device for use with a molding material, the molding device comprising:
- a die having a minute shape formed thereon;
- a transfer mechanism for transferring a shape of the die onto the molding material by bringing the die into contact with the molding material and applying pressure thereto;
- a mold releasing mechanism for releasing the molding material from the die sequentially from one edge to another edge of a transfer part on the molding material, the transfer part being a part onto which the shape of the die has been transferred;
- and
- a mold releasing force detecting mechanism for detecting a mold releasing force when the molding material is released from the die,
- wherein a molding device is configured to output an alarm signal if a number of times the mold releasing force becomes equal to or higher than a mold releasing force value preset in conformity to the molding material has reached a preset number of times, and
- wherein the molding device is configured to output the alarm signal if a number of times the mold releasing force at a specific position in the transfer part becomes equal to or higher than the mold releasing force value preset in conformity to the molding material has reached the preset number of times.
