Inclined extractor in transverse sliding block

Abstract

The invention discloses an inclined extractor in a transverse sliding block, comprising a transverse sliding block (1), an inclined mandrel block (2), a spring (3), a stop block (4), a limit pin (5) and an oil cylinder (6), wherein the inclined mandrel block is arranged in the transverse sliding block; and when the oil cylinder drives the transverse sliding block to transversely demould, the inclined mandrel block is driven by the stop block to slide and extend out of the transverse sliding block in an inclined manner so that a molded surface of the inclined mandrel block is extracted in the inclined manner to demould along an outer sidewall barb structure of a product longitudinally. Through the technical scheme of the invention, the inclined extractor prevents problems and defects of complex structure, high machining cost and long manufacturing period in the prior art; and the inclined mandrel block is arranged in the transverse sliding block so that an injection mould for extracting the outer sidewall barb structure of the product to demould in the inclined manner realizes purposes of simplifying the structure, reducing the cost and shortening the manufacturing period.

Description

technical field [0001] The invention relates to an oblique pull-out device for an injection mold, specifically refers to a device which is arranged in a horizontal slider and is used for oblique core-pulling and demoulding of a core block embedded in an undercut structure on the outer side wall of an injection molded product. Slanted drawer in slide. 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. Aiming at the oblique ejection of the undercut structure on the outer wall of the product, the prior art usually adopts to make the horizontal slider into a special-shape...

AI Technical Summary

Problems solved by technology

Aiming at the oblique ejection of the undercut structure on the outer wall of the product, the prior art usually adopts to make the horizontal slider into a special-shaped structure with two parts conforming to each other. The core-pulling block is arranged on the side of the movable mold, and the demoulding is realized by pulling the core inside the inclined top; in the above-mentioned scheme 1, there is a relatively high thin-walled area at the contact part between the horizontal slider and the fixed-mould movable mold, which reduces the strength of the mold and is relatively The high undulation area will also bring processing difficulties and increase the processing cost; the above-mentioned scheme two, the mold structure is complex, the processing cost is high, and the mold manufacturing period is increased; therefore, the existing technology has the problems of complex structure, high processing cost and long manufacturing period and deficiencies
