- the object of the present invention is to forcibly release the sticking of the glass element molded product, to prevent cracking of the molded product and damage to the upper and lower cores, and to reliably release the molded product.
- the object of the present invention is to provide a molding die for glass elements that enables smooth automatic conveyance by leaving it in the lower mold when the mold is opened, and enables continuous molding.
- the present invention provides a glass element material disposed between a pair of upper and lower molds, and heats and presses the pair of molds and the glass element material.
- a mold for molding glass elements in a molding apparatus for molding glass elements An upper core formed with an upper molding surface of the glass element, a lower core that forms a lower molding surface of the glass element and has an outer diameter larger than the outer diameter of the upper core, and the upper core
- An upper cavity die that is slidably fitted to the outer peripheral side surface, a lower cavity die that is slidably fitted to the outer peripheral side surface of the lower core, and the upper core and the upper cavity die are supported above them.
- the residual forcing means includes an elastic member disposed between the upper surface of the lower cavity and the upper die plate, and the upper die plate includes the upper core.
- the upper cavity die is engaged so that the upper cavity die and the upper cavity die can be moved upward by a body. And a department.
- the locking portion is screwed into the upper surface portion of the upper cavity die, and a stopper bolt that regulates a predetermined distance between the lower surface of the upper die plate and the upper surface of the upper cavity die, and the head portion of the stubber bolt And a stepped hole formed in the upper die plate.
- the elastic member is a heat-resistant elastic member containing ceramics, preferably a dish panel made of Inconel made of Incone earth.
- a heat-resistant coil panel or plate panel may be used instead of the dish panel.
- the upper core force when the mold is opened, can be reliably released when the glass element molded product sticks to the upper core, and can be reliably left on the lower core. This prevents cracking of the glass element molded product and breakage of the core, and ensures that the molded product remains in the single-open state, allowing smooth removal of the molded product and automatic conveyance, ensuring continuous molding cycles. Can be made. Brief Description of Drawings
