Device for movably supporting insert

Abstract

The invention discloses a device for movably supporting an insert. The device comprises a wedge-shaped slider pair (1), an oil cylinder (2) and movable struts (3). According to the device formed by the wedge-shaped slider pair, the oil cylinder and the movable struts, the wedge-shaped slider pair is formed by a transverse wedge block and a longitudinal wedge block; the oil cylinder is connected with the transverse wedge block, and the movable struts are connected with the longitudinal wedge block; the transverse wedge block is driven by the oil cylinder to make left-right transverse movement, and the longitudinal wedge block is used for converting the transverse movement of the transverse wedge block into longitudinal movement. According to the technical scheme, when the device works, the movable struts are driven by the oil cylinder to synchronously retreat by virtue of the wedge-shaped slider pair in the boosted plastic filling process of injection molding, and the space formed by retreating of the movable struts can be filled, so that processed blind holes of a product can be eliminated, and the problem and defect of processed blind holes in the prior art can be solved. The device for movably supporting an insert can be applied to an injection mould, and can achieve the aim of eliminating processed blind holes of an injection moulding product requiring transverse or tilting demolding.

Description

technical field [0001] The invention relates to an injection mold, in particular to a device for supporting a movable support insert for an injection mold to support a metal insert inside an injection molded product. 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. Metal inserts are called inserts for short. [0003] For injection molded products with inserts inside, hereinafter referred to as products, a support mechanism for supporting inserts needs to be provided in the injection mold. The support mechanisms in the prior art are all fixed, and the fixed support m...

AI Technical Summary

Problems solved by technology

[0003] For injection molded products with inserts inside the injection molding, hereinafter referred to as products, a support mechanism for supporting inserts needs to be set in the injection mold. The support mechanisms in the prior art are all fixed, and the fixed support mechanism is suitable for products that are demolded longitudinally. For products that require lateral or oblique demoulding, the fixed support mechanism will leave an unacceptable but inevitable process blind hole on the outer surface of the product to support the insert. Therefore, the prior art has the problem of process blind holes and deficiencies
