Multi-angle stacking core pulling mechanism of injection mold

Abstract

The invention relates to a multi-angle stacking core pulling mechanism of an injection mold. The multi-angle stacking core pulling mechanism comprises a movable mold and a fixed mold, wherein a multi-angle core pulling mechanism is arranged on the movable mold, an upper core pulling sliding block and a sliding block guide seat are arranged above the multi-angle core pulling mechanism, the upper core pulling sliding block can slide in the sliding block guide seat, and both the sliding block guide seat and an upper oil cylinder are installed on the movable mold; the multi-angle core pulling mechanism comprises a lower oil cylinder, a driving sliding block and two lower core pulling sliding blocks, the driving sliding block is driven to slide in the movable mold by the lower oil cylinder, aninverted V shape is formed on the end surface, which is far from the lower oil cylinder, of the driving sliding block, guide sliding blocks are fixedly installed on two inclined planes of the invertedV-shaped end surface of the driving sliding block respectively, guide chutes are respectively formed in the end surfaces, which are close to the driving sliding block, of the two lower core pulling sliding blocks, guide sliding plates which are matched with the guide chutes are arranged on the guide sliding blocks, the tops of both walls of the guide chutes are bent inwards so as to hook the guide sliding plates, and the lower oil cylinder is also installed on the movable mold. According to the multi-angle stacking core pulling mechanism, longitudinal and transverse core pulling at differentangles can be realized, and the multi-angle core pulling requirement that a plurality of core pulling mechanisms cannot be arranged in limited space is satisfied.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a multi-angle stacked core-pulling mechanism for injection molds. Background technique [0002] The core-pulling mechanism is one of the most common mechanisms in injection molds, and is generally designed at the undercut position of the product. At present, the commonly used core-pulling mechanism is that the inclined guide column drives the core-pulling slider to perform core-pulling, that is, when the movable and fixed mold is opened, the inclined guide column drives the core-pulling slider to move, so that the core is separated from the product to facilitate product demoulding. However, the conventional inclined guide column drives the core-pulling slider to move in only one direction. When the core-pulling is longitudinally and in multiple directions in a small space, the conventional core-pulling scheme will no longer be applicable. Contents of the invention [0...

Problems solved by technology

However, the conventional slanted guide column drives the core-pulling slider to move in only one direction. When there are longitudinal and multiple directions of core-pulling in a small space, the conventional core-pulling scheme will no longer be applicable.
