The present invention relates to a furnace opening and closing apparatus for a tempered glass manufacturing device, the apparatus for opening and closing a door, which covers an upper opening side of a furnace, when a jig (120), which is loaded with plate glass (120), is stored in a transfer unit part (200), which has a transfer casing (210), and is transferred above the furnace (410) for each procedure and the transferred jig (120) is stored in the furnace (410) or pulled again and transferred after each procedure has been completed. The present invention provides a furnace opening and closing apparatus for a tempered glass manufacturing device, the apparatus comprising: a furnace storage frame (105) which has a form of a frame in which woven are a plurality of supports that cover and are disposed around a furnace (410); a rising and falling frame (153) which is disposed so as to be raised and lowered by means of a cylinder (162) such that interference with an upper opening side of the furnace (410) does not occur on the furnace storage frame (105) and which at the same time is placed and assembled on both lateral sides of the furnace storage frame (105) so as to face one another; and a door (151) which opens or closes by sliding in both directions, by means of an opening and closing means (150), along a rail beam (152) that integrally extends on the upper end of the rising and falling frame (153) and longer than the width of the furnace (410). |
