Yes.
In proper English, to create the "if-then" conditional sentence, you need one of the below combinations. The conditional tense (would x) can only be used in the "then" part of any conditional sentence.
1) If future tense, then future tense: Typically used for two long off events that are strongly related. This conditional pairing is rare. Ex. If the cylinders will lock, then the dam will burst.
2) If present tense, then present tense: Typically used for habitual events. Ex. If I have homework, then I do not play with my friends after school.
3) If present tense, then future tense: Typically used for a singular event in the future that is dependent on some intermediary event. Ex. If it rains, I will not go to the movies.
4) If past tense, then conditional: Typically used to state a counterfactual in the recent past or present. Ex. If it rained, I would stay inside. (It did not rain and therefore he did not stay inside.)
5) If pluperfect, then conditional perfect: Typically used to state a counterfactual in the non-recent past. Ex. Had I done my homework, I would not have failed all of my classes. (I did not do my homework and thus I failed all of my classes.)
