Disclosed is an apparatus for removing the wax of a tooth model, comprising: a body (10) which has an installation space (11) therein and a first door (12) at one side closing and opening the installation space (11) depending on whether the body is operating； a chamber (20) which is arranged at one side of the installation space (11) and has a working space (21) which is tightly formed within the chamber and at which at least one case member (23) is installed to accommodate a tooth model (70) and a first door closing and opening the working space (21) depending on whether the chamber is operating； a steam/hot water generation device which is arranged at the lower portion of the installation space (11) and generates steam and hot water to remove the wax residing in the tooth model (70)； and a supply pipe part (40) which is extended from the steam/hot water generation device to be connected to the chamber (20) and selectively supplies steam or hot water to the chamber depending on whether the steam/ho water generation device is operating. The supply pipe part (40) extends from the steam/hot water generation device to allow steam and hot water to discharge, respectively, merges into one pipe and then divides into a first division pipe (41) and a second division pipe (42), wherein the first division pipe (41) is connected to the working space (21) within the chamber (20) to firstly supply steam to the working space (20), and the second division pipe (42) is connected to the case member (23) within the working space (21) to secondly supply steam and then thirdly supply hot water to the working space (20).개시된 본 발명에 따른 치아모형의 왁스 제거장치는, 내부에는 설치공간(11)이 형성되고, 일측에는 작동여부에 따라 설치공간(11)을 개폐한는 제 1 도어(12)가 구비되는 본체(10)； 설치공간(11) 일측에 구비되고 내부에는 치아모형(70)을 수용하는 적어도 하나 이상의 케이스부재(23)가 설치되는 작업공간(21)이 밀실하게 형성되며, 일측에는 작동여부에 따라 상기 작업공간(21)을 개폐한는 제 2 도어(22)가 구비되는 챔버(20)； 설치공간(11) 하부에 구비되고 치아모형(70)에 잔존 된 왁스의 제거를 위한 스팀 및 온수가 발생되는 스팀/온수 발생장치(30)； 및 스팀/온수 발생장치(30)로부터 연장되어 상기 챔버(20) 측에 연결되며 상기 스팀/온수
