Abstract
The invention relates to a porous oblique core drawing mechanism for an injection mold. The porous oblique core drawing mechanism for the injection mold comprises a fixing device and an A plate, wherein a core drawing device and stuff screws are arranged between the fixing device and the A plate; and the core drawing device is connected with the fixing device. According to the porous oblique core drawing mechanism for the injection mold, by adopting arrangement of the stuff screws between the fixing device and the A plate, in the mold opening process, after mold opening is carried out on the fixing device with a certain distance firstly, and the A plate normally carries out mold opening; in addition, by adopting connection of pulling blocks and a cushion plate through the stuff screws respectively, insert pins penetrate through insert pin sleeve plates and enter mold cavity through large inserts, and the insert pin sleeve plates and the insert pins are driven by the pulling blocks respectively to carry out mold opening in the guiding direction. The porous oblique core drawing mechanism for the injection mold is reasonable in design and is suitable for large-scale popularization.
