A method for setting up a program profile in the control of an injection speed of injection molding machines where a dwelling phase switching position Pc, a filling stroke L or an injection starting point Ps, a maximum speed ratio Rvm and a initial speed ratio Rvs to the maximum speed mentioned in the specification of the molding machine, and an initial speed period ratio Rps to the filling stroke L or the injection starting position Ps are inputted to a profile setting means; in the profile setting means, the dwelling phase switching position Ps and the filling stroke L or the injection starting position Ps are directly set up according to the inputted values; and the maximum speed Vmax, the initial speed Vs and the initial speed period are set up by automatic computing using the maximum speed ratio Rvm and the initial speed ratio Rvs and the initial speed period ratio Rps as parameters; thereby all aspects of the profile are set up automatically.
