Pushing and sliding composite slanted motion mechanism and pushing and sliding composite slanted motion mold

Abstract

The invention provides a pushing and sliding composite slanted motion mechanism. The pushing and sliding composite slanted motion mechanism comprises a core pulling assembly and a slanted ejection assembly. The core pulling assembly comprises a sliding block, a sliding block insert, a pressure bar and a sliding block seat. The sliding block is mounted on the bevel of the sliding block seat throughthe pressure bar and can slide. The lower end of the sliding block insert is fixedly connected with the sliding block, and the upper end of the sliding block insert is used for forming a slanted outer hole of a product and completing core pulling under driving of a movable mold part. The slanted ejection assembly comprises a slanted ejector block, a slanted ejection locking piece and a slanted ejection base. The slanted ejector block is locked onto the slanted ejection base through the slanted ejection locking piece, and the slanted ejection locking piece can slide freely. The slanted ejectorblock is used for pushing out a formed product in a slanting mode for demolding. The upper end of the sliding block insert is located in a mold core insert before core pulling and is drawn out from the mold core insert after core pulling. The invention further provides a pushing and sliding composite slanted motion mold comprising the pushing and sliding composite slanted motion mechanism. Through the pushing and sliding composite slanted motion mechanism and the pushing and sliding composite slanted motion mold, the problem that an existing mold is complex in structure and not easy to operate during slanting short-distance core pulling. The pushing and sliding composite slanted motion mechanism and the pushing and sliding composite slanted motion mold are simple in structure, convenientto manufacture and reliable in operation.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to a push-slide composite oblique motion mechanism and a push-slide composite oblique motion mold. Background technique [0002] Slanted holes often appear in the design and manufacture of parts. Since the oblique hole is at a certain angle to the mold opening direction, the parts generally cannot be demolded directly, so it is necessary to consider the problem of oblique core pulling when designing the mold structure. [0003] At present, the oblique core-pulling methods for plastic molds mainly include: one is to drive the slider to pull the core through the oblique guide column; It is to make the inclined core of the fixed mold into an insert, and take it out manually after the mold is opened. Although the first two methods can achieve core pulling in structure, they are always a single core pulling. When some plastic products with special structures need to pull cores in 2...
