Die with universal thread-twisting mechanism

Abstract

The invention discloses a die with a universal thread-twisting mechanism, and aims at providing a thread-twisting mechanism with higher suitability and lower requirements on the machining accuracy of the die. The thread-twisting mechanism comprises a drive wheel assembly, a plurality of first driven wheel assemblies, a plurality of second driven wheel assemblies and a plurality of thread-twisting core assemblies, wherein the thread-twisting core assemblies are connected with the second driven wheel assemblies through a universal assembly. The thread-twisting mechanism has the following beneficial effects: the angles of thread-twisting cores can be randomly changed because the thread-twisting core assemblies are connected with the second driven wheel assemblies through the universal assembly, the axes of the thread-twisting cores can be parallel or unparallel to the axes of the second driven wheel assemblies, thus thread-twisting can also be carried out through the universal thread-twisting mechanism when a product is provided with a plurality of threads and the axes among the threads are unparallel; and in addition, the axis distances among the thread-twisting core assemblies are variable because the thread-twisting core assemblies are connected with the second driven wheel assemblies through the universal assembly, thus the universal thread-twisting mechanism is capable of providing great suitability for reducing the machining accuracy of the die, and reducing the cost.

Description

technical field [0001] The invention relates to a mould, in particular to a mould, for a universal twisting mechanism. Background technique [0002] With the continuous advancement of technology and the continuous development of the mold industry, the design of plastic parts is becoming more and more complex, and the requirements for molds are also getting higher and higher; there are more than one thread for a single plastic part, and the axis of the thread is not parallel The situation also often occurs, the mold structure of the prior art needs to adopt two independent twisting teeth systems that do not interfere with each other; in addition, the existing mold structure, a set of molds is equipped with a set of twisting teeth mechanism, when the size of the mold base When they are the same, they cannot share the same set of twisting teeth system due to the size difference between the twisting teeth cores. Contents of the invention [0003] Aiming at the deficiencies of...
