PURPOSE: A system form for a box structure molding is provided to smoothly move an inner mold by minimizing the frictional force between the two inner molds. CONSTITUTION: A system form for a box structure molding comprises a first inner form(110), a second inner form(120), a first support(210), a second support(220) and a hydraulic jack(300). The first inner form and the second inner form are able to be installed with the one end contacting with each other. The first support and the second support is respectively combined to the first inner form and the second inner form to be arranged to be mutually crossed. Both ends of the hydraulic jack are combined in the first support and the second support. The hydraulic jack changes the relative location of the first inner form and the second inner form by changing distance between the first support and the second support. |
