Abstract

The invention provides a Christmas tree branch integrated molding injection molding process, which comprises the following steps: assembling a male mold and a female mold, forming a feeding hole on at least one of the male mold and the female mold, forming N cavities after the male mold and the female mold are assembled, communicating the feeding hole with at least one of the N cavities, and communicating one cavity with the other N-1 cavities, wherein N is a natural number greater than or equal to 2; inserting N metal strips with PE and/or PVC leaves into the N cavities respectively; injecting hot melt plastic from the feeding hole, and filling the N cavities with the hot melt plastic; cooling the hot melt plastic, and forming Christmas tree branches in the N cavities; and demolding the male mold and the female mold, and taking out the molded Christmas tree branches. The male mold and the female mold are assembled, the long strip with the PE/PVC leaves is inserted into at least two communicated cavities, the cavities are filled with molten plastic, branch bodies and branches of the formed Christmas tree branches are fixedly connected through the molten plastic, the branches cannot be separated from the branch bodies even if the branches shake violently, and the structural integrity of a Christmas tree is guaranteed.

Description

technical field [0001] The invention relates to the technical field of Christmas trees, in particular to an injection molding process for integrally forming Christmas tree branches. Background technique [0002] The Christmas tree is a decorative tree for Western Christmas. It symbolizes the tree of life or the tree of knowing good and evil, and is the main component of Christmas. The injection molding process has a short production cycle, high productivity, and can produce structures with complex shapes. Therefore, the injection molding process is widely used in the production of Christmas tree branches. [0003] The Christmas tree branch includes a branch body and branches. In the existing Christmas tree branch injection molding process, an injection mold is used to inject the branch body with jacks, and then the branches are manually inserted into the jacks of the tree branch body. But the Christmas tree branch that existing injection molding process is made is shaken fo...
