(A1) forming section A2, the annealing section A3, and the cooling section A4, which are arranged in this order on the rotating / endless track, Providing a plurality of lower molds 110 mounted on the carrier 120 and providing a same path movable lower mold part 100 in which the glass is repeatedly moved in the same path while the glass is loaded on the lower molds 110 S100) and:

(2) a plurality of carriers are installed at predetermined intervals in a fixed state (position fixation without rotational movement) in the preheating area A1, the forming area A2 and the annealing area A3 among the paths through which the carrier 120 moves (S200) for heating the lower molds (110) by elevating the heater block (210) when the lower molds (110) are stopped and located at the upper part )Wow:

3) a glass injection step 300 in which the glass G is injected into the lower mold 110 located in the injection region by using the injection means unit 500;

4) When the lower mold 10 mounted on the carrier 120 is moved by one step and the lower mold 10 into which the glass is put is positioned and stopped in the preheating area A1, the first heater block 210-1 is raised A preheating step (S400) of conduction heating the lower molds (110);

5) When the heater block 210 descends and the carrier 120 further moves by one step and the preheated lower mold 110 reaches the forming area A3, the second heater block 210-2 (S500) of heating the lower molds (110) by elevating the lower molds (110);

6) The elevating type upper mold part 300 provided in a state where the carrier 120 is fixed to the forming area A2 (the position is fixed without rotating and moving) among the paths in which the carrier 120 moves moves down the upper mold 310, A forming step (S600) of forming the heated glass (G) in the heating step (S500);

7) When the second heater block 210-2 descends and the carrier 40 further moves by one step and the lower mold 10 having undergone the forming step S600 reaches the annealing area A4 An annealing step (S700) for annealing the formed glass by conducting the contact heating of the lower portion of the lower mold (10) by the third heater block (210-3) rising;

8) a cooling and extraction step (S800) of cooling the formed body through the annealing step (S60) and taking out the molded glass of the lower mold (10) after cooling;
A plurality of lower molds moving repeatedly along the same path, and a vertically movable upper mold having a fixed position.
10. The method of claim 9,
The lower mold 110 has a vacuum adsorption fixing part 115,
When the alignment state of the glass to be injected into the lower mold 110 is confirmed by the injecting unit 500 in the glass injecting step 300,
Wherein the step of adsorbing and holding the molding glass is performed before the vacuum adsorption fixing unit (115) moves for the preheating step (S400). A method of molding a smartphone glass using a lifting upper mold.
