Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold oblique ejection slider mechanism. Background Art

[0002] Injection mold generally refers to injection molding, which is also called injection molding. It is a molding method of injection and molding, which uses a slanted top slider to form an undercut groove. In the prior art, some injection molded parts have a structure blocking the outside of the undercut, making it difficult for the slanted top slider to detach from the undercut of the injection molded part, resulting in less than ideal use effect.

[0003] For example, patent announcement number CN218227691U is specifically a mechanism for an injection mold to eject a slider obliquely, including a slider and an oblique top. The slider and the oblique top obliquely penetrate the injection molded product. The oblique top covers the guide hole of the injection molded product and is installed at the bottom of the slider. When the mold is opened, the slider is first pulled out of the undercut of the injection molded product to solve the problem of a long exit stroke required for a long oblique top. Then, the oblique top only needs to move at the bottom of the slider to eject the guide hole of the injection molded product. The demoulding structure is designed as a combination of a slider and an oblique top. This structure greatly shortens the exit stroke of the oblique top and reduces the mold development cost. However, this problem exists.

[0004] For example, patent publication No. , specifically, there is a problem that there is a structure blocking the outer side of the undercut of some injection molded parts, making it difficult for the inclined top slider to detach from the undercut of the injection molded part, resulting in unsatisfactory use effect.
