Abstract

The invention discloses an automatic screw releasing device and an injection mold comprising the same. The screw releasing device comprises a power source, a first transmission mechanism, a driving shaft, a second transmission mechanism and a driven shaft. The driven shaft comprises a first driven shaft, a second driven shaft and a connecting piece; the upper end of the second driven shaft is provided with a mold core or mold cavity with screw thread; the lower end of the second driven shaft is connected with the upper end of the first driven shaft by the connecting piece; the second driven shaft rotates synchronously with the first driven shaft, and can move axially relative to the first driven shaft; the first driven shaft is connected to the driving shaft through the second transmission mechanism; and the driving shaft is connected with the power source through the first transmission mechanism. The automatic screw releasing device provided by the invention has high production efficiency and more compact structure, thereby reducing manufacturing cost of the mold.

Description

technical field [0001] The invention relates to parts of injection molds, in particular to an automatic thread removal device and an injection mold with the automatic thread removal device. Background technique [0002] At present, for injection molding molds with threaded plastic products, the commonly used thread removal methods mainly include the following: [0003] 1. Manual thread removal method. After demoulding, manually remove the insert to achieve the effect of demoulding. The efficiency of this production method is very low; [0004] 2. Automatic thread removal method, that is, the hydraulic motor drives the long rack to move back and forth, so that the gear meshing with the rack rotates, thereby driving the threaded insert to rotate and eject the plastic product. The disadvantage is that the size of the mold base is too large due to the insufficient compact structure caused by the long rack, thereby increasing the manufacturing cost of the mold.
