Pallikal and her women's doubles partner Joshna Chinappa, former Commonwealth champions, entered the title decider without having to play a shot after New Zealand's Joelle King and Amanda Landers-Murphy, the top seeds, pulled out on Saturday night, allowing the Indian pair a walkover.
Dipika and Joshna, seeded third, will now face English second seeds Sarah-Jane Perry and Alison Waters for the women's doubles gold medal.
In the mixed doubles, Dipika Pallikal and Saurav Ghosal, World Doubles silver medallists from 2016, received a walkover after Wales' Peter Creed and Emily Whitlock pulled out of their final Group B encounter.
The points meant the Indian squash team topped its group and entered the quarterfinals.
Dipika and Saurav then toppled England's Patrick Rooney and Georgina Kennedy 11-6, 11-7 in their final-eight clash before overcoming Wales' Joel Makin and Tesni Evans 11-9, 11-5 in the semis.
Fourth-seeded English pair Adrian Waller and Alison Waters will be the second-seeded Indian duo's opponents in the mixed doubles final.
Meanwhile, Vikram Malhotra and Joshna Chinappa, the other Indian mixed doubles pair in action, finished third in Group A and will be contesting against Mohammad Syafiq Kamal and Aifa Azman for a ninth-place finish.
Asian Games bronze medallist Ramit Tandon and Vikram Malhotra, India's only entry in men's doubles, won their two matches and will vie for a 17th place finish against Wales' Elliott Morris and Owain Taylor.
The Indian pair had finished third in Group E of their division.
