Abstract

The invention discloses a liftout device for a screw-tooth mold. The liftout device comprises a front mold and a rear mold. A mold cavity is arranged between the front mould and the rear mold. A mold insert is disposed inside the mold cavity. The invention is characterized in that a screw mechanism which can rotate relative to the mold insert is arranged inside the rear mold; the outer wall of the rear mold is provided with a driving device capable of driving the screw mechanism to rotate; the driving device is connected with the screw mechanism through a transmission mechanism; and a lifting driving mechanism capable of making the screw mechanism to rise so as to lift-out a product inside the mold insert during the mold-opening rotation process is arranged inside the rear mold. The invention aims to overcome insufficiencies in the prior art and provide a spiral liftout mechanism which has a simple structure, is convenient to install and can effectively prevent a product from being damaged during the liftout process.

Description

technical field [0001] The invention relates to an ejector device for a mold with screw teeth. Background technique [0002] The structure of the existing ejection mechanism used for thread molds is relatively complicated, and the product ejection process sometimes causes product damage, which cannot meet the production requirements. [0003] Therefore, the existing screw ejector mechanism needs to be further improved. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies in the prior art, and provide a screw ejection mechanism with simple structure, convenient installation and effective prevention of product damage during ejection. [0005] In order to achieve the above object, the present invention adopts the following scheme: [0006] An ejector device for a mold with screw teeth, comprising a front mold and a back mold, a mold cavity is arranged between the front mold and the back mold, and a mold core is arranged in t...
