Abstract
Molds for compound injection molding, including at least a first mold, a second mold, and a third mold; the first mold has a first mold cavity for injection molding of a first component; the second mold has a shielding cavity for shielding the first component and a second mold cavity for injection molding of a second component; the third mold has positioning cavities for positioning the first component and the second component, and a third mold cavity for injection molding of a third component; the positioning cavities are in communication with the third mold cavity, so that the third component can be connected integrally with the first component and the second component to form a one whole piece of product.
Claims4
Molds for compound injection molding, comprising at least a first mold, a second mold, and a third mold;
- the first mold is provided with a first mold cavity for forming a first component by injection molding;
- the second mold is provided with a shielding cavity for shielding the first component and a second mold cavity for forming a second component by injection molding;
- the third mold is provided with positioning cavities for positioning the first component and the second component, and a third mold cavity for forming a third component by injection molding;
- the positioning cavities are in communication with the third mold cavity;
- a melting point of a plastic injected into the third mold cavity is lower than that of a plastic injected into the first mold cavity and a plastic injected into the second mold cavity, and the plastic injected into the first mold cavity, the plastic injected into the second mold cavity, and the plastic injected into the third mold cavity do not mutually dissolve, thereby allowing the third component to be connected integrally with the first component and the second component to form a one whole piece of product.
