PURPOSE: A guide housing for compensating heat expansion of a low pressure casting machine is provided to stably open or close dies, thereby greatly contributing to increase of productivity by compensating the heat expansion as freely and automatically covering a horizontal moving distance of the housing since the axis holes correspond to the heat expansion of the lower dies adhering plate. CONSTITUTION: In an upper dies adhering plate (5) in which axis holes (5-1) are inserted between housings vertically installed at the four corners of a lower dies adhering plate, the guide housing for compensating heat expansion of a low pressure casting machine comprises key inserting grooves (5-2,6-2) diagonally formed on upper and lower circumferential surfaces of the axis holes (5-1) and upper and lower housing circumferential surfaces corresponding to the upper and lower circumferential surfaces of the axis holes (5-1); and joint bolts (6-5) and nuts (6-6) by which upper and lower housings (6) are jointed to the upper dies adhering plate (5) in the state that a guiding keys (6-1) are inserted into the key inserting grooves (5-2,6-2).
