Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to a circular arc structure with multiple inclined holes. Background Art

[0002] In the prior art, a needle is installed on the slider seat of the slider mechanism to facilitate the side core pulling forming of the through hole. However, the slider seat is affected by the inclined guide column to make a linear motion, and the movement direction of the needles installed on the slider seat is the same. Figure 6 In the case of the plastic shell shown, the outer surface of the plastic shell is an arc-shaped structure, and the outer surface of the plastic shell has multiple through holes. Affected by the curvature of the plastic shell, the axes of the through holes are not parallel to each other and have different angles. The multiple through holes on the outer surface of the plastic shell require multiple side core pulling structures for molding. Since the outer surface of the plastic shell has multiple through holes with different angles, and the intervals between adjacent through holes are small. Limited by the volume of the slide mechanism and the mold itself, it is difficult to install multiple slide mechanisms. It is difficult to process all through holes by side core pulling at one time.
