AI Technical Summary
Traditional crystal injection molding is difficult to release, resulting in inefficient production efficiency.
A crystal bead injection mold is designed, using a beveled mating surface and a conical injection molding channel, combining the structure of the spring and the ejection member to achieve a molding process that is convenient for mold release.
Through the setting of the inclined surface and the design of the tapered channel, the resistance of the molded parts to demolding can be effectively reduced and the demolding efficiency can be improved. At the same time, the coordination between the spring and the ejection part ensures the smooth ejection of the crystal beads.

Technical Field
[0001] The utility model belongs to the technical field of injection-molded crystal beads, and particularly relates to a crystal bead injection mold. Background Art
[0002] As the name implies, a crystal bead curtain is a curtain made of crystals. A bead curtain is a curtain formed by threading beads into vertical strings with a cord. Installing a bead curtain on the door of a room or outside the house serves a decorative and shielding purpose. Traditionally, the bead materials are generally plastics, glass products, or crystal materials. Crystal, also known as spar and crystal stone, now there are also injection-molded crystal beads. Acrylic (imitation crystal), scientifically named methyl methacrylate, is characterized by good transparency and rich cut surfaces, just like crystal, and has the reputation of "queen of plastics". Traditional crystal injection molding is difficult to demold, so it is very important to obtain a crystal bead injection mold that is easy to demold. Summary of the Utility Model
