Abstract

The invention discloses a molding die for an infusion bag, which includes a heat-synthesizing lamination line, the first heat-synthesis lamination line wraps around its end close to the infusion bag interface along the moving direction of the film belt of the infusion bag Deflect outward by a predetermined angle. The heat-synthesized lamination line closest to the unprocessed film tape is deflected outward at a predetermined angle around its end close to the interface of the infusion bag, so that the forming cavity closest to the unprocessed film tape becomes larger than the normal forming cavity, In order to offset the shrinkage of the finished infusion bag caused by the deformation of the side of the film tape close to the tail of the infusion bag. Therefore, the forming tool can effectively solve the problem that the cavity of the first infusion bag made by the forming mold is too small along the moving direction of the film belt of the infusion bag.

Description

technical field [0001] The invention relates to the field of manufacturing mechanical equipment, more specifically, to a molding die for an infusion bag. Background technique [0002] At present, the forming molds of the non-PVC film soft bag large infusion automatic production line adopt one-time complete bag blanking forming molds. Specifically, the strip-shaped film material is used to pass through the forming mold section by section, and the forming mold presses the infusion bag and cuts the infusion bag. Features. The molding die is mainly composed of an upper die and a lower die. There is a molding cavity for infusion bag molding in the middle of the forming mold. According to the model and production capacity, the forming mold generally has one film and one cavity, or even one mold with multiple cavities. The use of one mold with multiple cavities can speed up the molding speed to improve productivity. [0003] In the prior art, the molding die is generally divided...
