The utility model relates to the technical field of garment production, and discloses an acrylic template pocket opening device for garment production, which comprises a bottom plate. A pocket containing groove is formed in the upper surface of the bottom plate, and a first sewing opening is formed in the position, close to the pocket containing groove, of the bottom plate. A first positioning cover plate is arranged at the position, located in the pocket containing groove, of the bottom plate. Clamping plates which are symmetrically arranged and used for folding the edge of a pocket are arranged on the bottom plate in a sliding manner; according to the acrylic template pocket opening device for garment production, by optimizing the design of the acrylic template pocket opening device, the folding edge of a pocket can be fixed more quickly and conveniently, an iron does not need to be used for shaping, preparatory work before pocket opening and sewing is reduced, the production efficiency is improved, and the production cost is reduced. Therefore, the working efficiency of the whole bag opening procedure is remarkably improved, the using effect of the structure is improved, and the actual using requirement is met.
