Problems solved by technology

[0002] For the core-pulling demoulding of injection molded products with arc inner holes, the prior art adopts the oil cylinder to drive the rotating arm to rotate, and the rotating arm drives the arc sliding core to pull the core out of the mold; or the oil cylinder drives the rack, the rack Drive the gear to rotate, and the gear drives the arc sliding core to pull out the mold through the eccentric shaft. These schemes have complex mechanisms, large volume, high cost, and are prone to failure during application, low reliability, and affect production efficiency. Therefore, the existing The technology has the problems and deficiencies of complex mechanism, large volume, high cost and low reliability

Abstract

The invention discloses an explorator core loosing apparatus for an arc sliding core. The apparatus comprises an arc loosing core (1), an arc slide block (2), an explorator (3) and a drive board (4). According to the invention, the apparatus composed of the arc loosing core, the arc slide block, the explorator and the drive board is utilized for opening a die, an inclined guide pillar drives a transverse slide block and the drive board to move transversely, a poking aperture in the drive board draws a poking pin on the arc slide block and drives the arc slide block with one end connected withthe arc loosing core to slide in an arc guiding chute of the explorator, and the arc slide block drives the arc loosing core to pull out a core from an arc bore tunnel of a product along the arc track of the arc guiding chute; therefore, the problems and shortcomings of complex construction, large volume, high cost and low reliability in the prior art are overcome; utilization of an injection mould which pulls out a core from a product that is provided with an arc bore tunnel by using the explorator core loosing apparatus enables the purposes of simplifying construction, reducing volume and cost and improving reliability to be realized.

Description

technical field [0001] The invention relates to a core-pulling and demoulding device for an injection mold, in particular to a circular arc used for the injection mold to pull the arc-shaped sliding core out of the arc-shaped inner hole channel of the product. Profile core pulling device for sliding core. Background technique [0002] For the core-pulling demoulding of injection molded products with arc inner holes, the prior art adopts the oil cylinder to drive the rotating arm to rotate, and the rotating arm drives the arc sliding core to pull the core out of the mold; or the oil cylinder drives the rack, the rack Drive the gear to rotate, and the gear drives the arc sliding core to pull out the mold through the eccentric shaft. These schemes have complex mechanisms, large volume, high cost, and are prone to failure during application, low reliability, and affect production efficiency. Therefore, the existing The technology has the problems and deficiencies of complex mec...
