Abstract

The multi-hole thread twisting device comprises a rear mold, the rear mold is provided with a cavity matched with a front mold and used for forming an injection product, the rear mold is provided with a thread twisting mechanism, the thread twisting mechanism comprises a first driving unit, a transmission unit and at least three thread cores, and the first driving unit synchronously drives the thread cores to rotate through the transmission unit; the transmission unit comprises a ring gear and tooth core gears matched with the ring gear, the number of the tooth core gears is in one-to-one correspondence with the number of the tooth cores, a through hole is formed in the center of the ring gear, inner teeth are arranged in the circumferential direction of the through hole, and the tooth core gears are arranged in the through hole and meshed with the inner teeth of the ring gear to form a planetary gear structure. The multi-thread core is driven by the planetary gear to rotate synchronously, and thread twisting operation in the injection molding process of a porous thread product is achieved.

Description

technical field [0001] The invention discloses a porous twisting device for an injection mold, which belongs to the technical field of mold manufacturing according to the International Patent Classification (IPC). Background technique [0002] Such as figure 1 As shown, a sanitary spool part A has three holes A1 on it, each hole needs to be threaded, and the distance between adjacent holes is relatively close. How to process such parts is a need for those skilled in the art solved problem. [0003] In the traditional injection molding process, after the parts are formed, they are taken out and threaded in the threading mechanism. [0004] Chinese document CN109719905A discloses an automatic screwing device for injection molds. The rack and gear mounted on the front template drive the connecting rod and the screw core to rotate, so that the screw core is screwed in along the shape of the screw. and unscrewing, the thread core is screwed in along the shape of the thread dur...
