Linkage slider core-pulling device of injection mold

Abstract

The invention discloses a linkage slider core-pulling device of an injection mold. The linkage slider core-pulling device of an injection mold is characterized by comprising a transverse wedge-shaped slider (1), a transverse rectangular slider (2), a core-pulling slider (3), a backing plate (4), a pull rod screw (5), a support plate (6) and an oil cylinder (7). A technical scheme of the linkage slider core-pulling device of an injection mold comprises that the transverse wedge-shaped slider is pulled by the oil cylinder to move horizontally and transversally; through guidance of a guide rod, the transverse wedge-shaped slider stuck slidably between the core-pulling slider and the transverse rectangular slider is pulled to move so that the core-pulling slider is longitudinally pulled out from the rear first; and through the pull rod screw, the transverse rectangular slider and the core-pulling slider are pulled to move horizontally with the transverse wedge-shaped slider which still moves horizontally and transversally so that transverse extraction of the core-pulling slider is finished. Compared with the prior art, the linkage slider core-pulling device of an injection mold overcomes the defects of large volume, high cost, high failure rate and low efficiency. The linkage slider core-pulling device of an injection mold enables an injection mould which is subjected to longitudinal core pulling and then is subjected to transverse core pulling to have the advantages of short volume, low cost, high reliability of work, and high production efficiency.

Description

technical field [0001] The invention relates to a demoulding and core-pulling mechanism for an injection mold, in particular to a slider core-pulling mechanism for an injection mold that is applied to an injection mold of an injection molded product with multiple external oblique ribs and is used to extract a core block embedded in the ribs of the product mechanism. Background technique [0002] The core-pulling and demoulding of the injection mold can be divided into longitudinal, transverse and oblique directions. The so-called longitudinal direction is along the opening and closing direction of the injection mold, the so-called transverse direction is the direction orthogonal to the longitudinal direction, and the so-called oblique direction is between the longitudinal direction and the transverse direction. direction.

Problems solved by technology

[0003] For the core-pulling of the external multi-ring lattice rib injection molding products, such as the core-pulling of the outer wall of the inner barrel of the fully automatic wave-wheel washing machine, it is necessary to perform a secondary core-pulling movement that is drawn back longitudinally, and then pulled out horizontally. The technology adopts a double-cylinder two-way asynchronous core-pulling mechanism, and the core block embedded in the product rib is pulled out and demolded by step-by-step joint extraction; this kind of mechanism is complicated, the mold occupies a large volume and high cost. There are many potential failure points in the circuit, oil circuit and many other system units of the coordinated control of the oil cylinder, which are prone to failure in actual injection molding production, which affects the stability, reliability and production efficiency of the mold application; therefore, the existing technology has Problems and shortcomings of large volume, high cost, easy failure, and low efficiency
