Longitudinal cylinder drive and duplex sliding block inclined core-loosening device arranged inside moving die

Abstract

The invention discloses a longitudinal cylinder drive and duplex sliding block inclined core-loosening device arranged inside a moving die. The inclined core-loosening device comprises a longitudinal sliding block (1), an inclined sliding block (2) and an oil cylinder. According to the invention, a duplex sliding block mechanism consisting of a longitudinal sliding block and an inclined sliding block is arranged in a moving die core, the longitudinal sliding block which is longitudinally arranged inside the moving die core is driven by the oil cylinder longitudinally arranged under a moving die plate, the longitudinal sliding block guides and drives the inclined sliding block to core-loosen and demould, wherein the inclined sliding block is arranged inside the movable die core, and one end of the inclined sliding block is provided with an interior position profile of a product. According to the technical scheme, the longitudinal cylinder drive and duplex sliding block inclined core-loosening device arranged inside the moving die, provided by the invention, overcomes the problems and defects of complex mechanism, large size and high cost of the prior art; by arranging the longitudinal-drive and inclined core-loosening inclined core-loosening device inside the moving die, an injection die which needs to be subjected to inclined core-loosening from the interior position of the product achieves the purposes of simplifying mechanism, shortening size and reducing cost.

Description

technical field [0001] The invention relates to a core-pulling and demoulding mechanism of an injection mold, in particular to an oblique core-pulling device for oblique core-pulling with a built-in oil cylinder in a movable mold for longitudinally driving a double slider from an internal position of a 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. Thin-walled injection molding products have two surfaces, one is the outside or the outside, and the other side is the inside or the inside. The so-called outside is the side of the product that looks outward, u...

Problems solved by technology

[0003] The core is pulled obliquely from the internal position of the product. The existing technology uses an inclined ejector rod to pull the core obliquely and an external oil cylinder to drive the core obliquely. The above method has a complicated mechanism, a large mold space, high mold cost, and the injection molding production It must occupy an injection molding machine with a large work opening for production, resulting in large horse-drawn carts and high production costs. Therefore, the existing technology has the problems and deficiencies of complex mechanism, large volume, and high cost
