Injection tube cutting device

Abstract

The invention relates to the technical field of machining of injection molding parts, in particular to an injection molding pipe cutting device. The injection molding pipe cutting device comprises a tubular machining table and a first outer gear, wherein the machining table is vertically arranged, the first outer gear is coaxially and rotationally connected to the upper end face of the machining table, two rotary shafts horizontally arranged in parallel are arranged below the machining table and rotationally connected with the machining table, the two rotary shafts are located on the two sidesof a vertical center axis of the machining table and fixedly connected with friction wheels which are symmetrical with respect to the vertical center axis of the machining table, an S-shaped pore duct is arranged in the first outer gear, and a hard pipe is arranged in the S-shaped pore duct in a sliding fit mode. The injection molding pipe cutting device can machine injection molding pipes of different specifications directly.

Description

technical field [0001] The invention relates to the technical field of injection molding parts processing, in particular to an injection molding pipe cutting device. Background technique [0002] The injection molding tube is made by mixing resin powder, stabilizer and other materials, and then crushing to obtain rubber particles, which are finally added to the extrusion injection molding machine. Injection molding pipes have many different diameter specifications, and thread-like grooves need to be processed on the outer surfaces of injection molding pipes of different diameters during production. The method adopted in the prior art is to use a fixture to fix the injection tube on the chuck of the lathe, start the main shaft of the lathe, and the chuck drives the injection tube to rotate. Every time the injection tube rotates with the chuck, the turning tool is evenly moved along the axial direction of the injection tube. Move a lead. [0003] The above method has the fol...

AI Technical Summary

Problems solved by technology

[0003] The above method has the following defects: 1. The turning tool must be accurately controlled to ensure that the turning tool moves evenly, and the movement of the turning tool must be well coordinated with the rotation of the injection molding tube

2. It is time-consuming and labor-intensive to install and disassemble the injection molding pipe for each processing, and for injection molding pipes of different diameters, the fixture must be replaced

3. The adjustment of the processing groove depth in the prior art relies entirely on manual operation, which has high requirements for workers and equipment, and the processing of injection molded pipes with different diameters requires frequent adjustment of tools

[0004] In summary, the existing injection molding pipe cutting device cannot directly process injection molding pipes of different specifications
