Description
The technical field is as follows:
the invention relates to a core-pulling delay mechanism of a double-color mold sliding block and a working method thereof.
The background art comprises the following steps:
due to the process characteristics of the double-color mold, when a product has an inverted buckle characteristic (an outer convex column), the mold design cannot adopt an inclined guide column and shovel machine structure, and an eccentric ejector rod is used for replacing the inclined guide column to realize the core pulling action of the sliding block; the eccentric ejector rod replaces a slide block core mechanism of an inclined guide post, so that the problem that a side core is loose and does not fall off during first-color molding of a double-color mold is solved, but a large demolding force exists during demolding of the slide block, the slide block is easily stuck with an inverted buckle characteristic, and phenomena such as whitening and breaking are caused in severe cases. The COC (cyclic olefin copolymer) material is very suitable for being used as a bracket of an automobile rain sensor due to excellent light transmission and weather stability, but the material has very poor toughness, so that a rotating shaft (back-off characteristic) is very easy to break when the material is demolded.
