[0002] An easy-to-demold slider injection mold is designed for plastic injection molding. The key lies in the design of the internal sliding component (slider), which enables complex-shaped plastic products to be demoulded smoothly. At the same time, through appropriate material selection and surface treatment, friction is reduced and mold life is extended. This mold is combined with refined process optimization to ensure stable operation during the production process, improve production efficiency and finished product quality.

[0003] In the prior art, most injection molds are designed for injection molding through a fixed injection molding seat, which makes it difficult to take the mold after the injection molding is completed. The mold needs to be taken with the help of tools or force, which causes damage to the mold, thereby affecting the use effect of the mold and also affecting work efficiency.

[0004] With respect to the structure of the prior art, the injection molding seat which is not easy to remove cannot directly and quickly remove the internal mold, thus making it impossible to perform injection molding of the next mold, which not only affects work efficiency but also easily causes damage to the mold, thereby increasing costs.
