Single-slider multi-directional core-pulling mechanism for injection mold

Abstract

The invention relates to a single-sliding-block multidirectional core-pulling mechanism for an injection mold. The single-sliding-block multidirectional core-pulling mechanism comprises a movable mold, a sliding block and a fixed mold. The fixed mold is fixedly connected with slant guide pillars used for driving the sliding block. The movable mold is provided with two core-pulling sliding blocks in a sliding mode. The sliding block and the core-pulling sliding blocks are provided with multidirectional guide-sliding mechanisms. The multidirectional guide-sliding mechanisms comprise movable moldinserts fixed to the movable mold. The top faces of the movable mold inserts are in an isosceles triangle shape, and the bottom faces of the movable mold inserts are in an isosceles trapezoid shape.Insert guide-sliding grooves are both formed in the two side oblique planes of each movable mold insert. The core-pulling sliding blocks are similar to be in a triangular prism shape. One side faces of the core-pulling sliding blocks are fixedly connected with insert guide-sliding blocks, and insert guide-sliding plates matched with the insert guide-sliding grooves in structure are arranged on theinsert guide-sliding blocks. Sliding block guide-sliding grooves are formed in the other side faces of the core-pulling sliding blocks. Two sets of sliding block guide-sliding blocks are fixedly installed on the end face, close to the movable mold inserts, of the sliding block. Sliding block guide-sliding plates matched with the sliding block guide-sliding grooves in structure are arranged on thesliding block guide-sliding blocks. By means of the single-sliding-block multidirectional core-pulling mechanism for the injection mold, core pulling in the mutually-crossed interference process canbe achieved in different directions, particularly the core-pulling direction.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a single-slider multi-directional core-pulling mechanism of an injection mold. 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 there are longitudinal and multiple directions of core-pulling in a small space, especially when the core-pulling directions interfere with each other, the conventiona...

Problems solved by technology

However, the conventional inclined 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, especially when the core-pulling directions interfere with each other, the conventional slider core-pulling scheme will no longer apply
