Abstract

The invention discloses a demolding device of an injection mold of thread products and the injection mold. The demolding device of the injection mold of thread products comprises a rack, a drive gear group, a drive shaft and a reversing gear group, wherein the rack is arranged on the injection mold; the drive gear group comprises at least two drive gears which are meshed sequentially, and one drive gear is meshed with the rack; the drive shaft is connected with and liked with the other drive gear in the drive gear group; the reversing gear group comprises at least two reversing gears which are sequentially meshed, wherein one reversing gear is connected with and linked with the drive shaft, and the other reversing gear is connected with and linked with the drive shaft of the injection mold. The demolding device is compact in structure, is convenient to operate, operates stably, is high in production efficiency, and has production advantage and economic benefit compared with a traditional common motor, the hydraulic control and servo motor control.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a demoulding device and an injection mold for an injection mold of a product with threads. Background technique [0002] Screw-type injection molded products with high requirements must adopt spiral demoulding, which usually uses a motor or oil motor located outside the mold to drive the threaded rotating core inside the mold to rotate axially through a reduction transmission device, and the screw thread injection molding products. [0003] For example, the invention patent with application number: 200910163720.9 discloses an injection mold thread synchronous automatic dethreading mechanism, such as figure 1 As shown, it includes: a driving gear, installed on a central shaft, and the central shaft is connected with the power mechanism and the transmission mechanism; a plurality of driven gears, each installed on a threaded core; a spring, set On the central shaft, an...
