The parts of the product are divided into upper and lower covers. The connection between the upper and lower covers is a typical plastic hinge connection, similar to the shape of a butterfly, so it is called a butterfly buckle flip cover. This kind of flip cover can be opened and closed multiple times and requires one molding. It is widely used. In washing products such as shampoo and shower gel.
- Flip over products belong to large-scale products. In order to avoid feed marks on the surface of plastic parts and ensure uniform feeding. This mold adopts a latent gate feeding method. And the feeding point is not obvious after the product is closed.
- In order to avoid joints on the surface of the plastic part, the upper and lower cover shapes of the plastic part are all designed on the movable mold. Since the inner surface of the upper cover is in the fixed mold, the product will stick to the fixed mold when the mold is opened. So it is necessary to design an ejection structure in the fixed mold.
- The design of the butterfly buckle flip requires co-injection molding with a two-color mold. So both the injection molding machine and the mold require precise control. YUEYI mould is committed to every detail.Strive to make every mold the best.
In order to improve the beauty of the product and facilitate the opening and closing of the product, we set an annular indentation at the mouth of the lower cover; the small holes in the upper and lower covers are precisely matched and the appearance is required to be smooth, and no obvious parting surface joints are allowed; when the upper cover is opened and closed, When it is used, it needs to be elastic, feel appropriately tight, and automatically reach the position; strive to achieve balanced elasticity and good appearance of each plastic part.
