Precise injection machine

Abstract

The invention discloses a precise injection machine, comprising a mould-closing mechanism and a headstock, wherein the headstock comprises a material tube, a screw, a feeding device and a screw driving device, the mould-closing mechanism and the headstock are arranged on the machine, a torsional deformation resistant round pipe is fixed in the machine, the round pipe penetrates through the machine longitudinally. The invention has the advantage: the motion parts such as the mould-closing mechanism, the ejaculation mechanism and the like have precise stroke, thus the precision is high.

Description

technical field [0001] The invention relates to an injection molding machine. Background technique [0002] In the existing injection molding machines, the machine base is not set as a solid base, because the main solid base is not only bulky, inconvenient for transportation and assembly, but also its material cost is also a consideration; therefore, most of the bases are It is hollow inside, and in addition to the advantage of saving materials, the hollow base can be set up for the pipeline wiring of the machine tool. However, the inherent part of the injection molding machine has a long wheelbase, so that different weights are loaded on the machine base by the various parts of the working tools at the upper end, resulting in torsion. The definition of torsion is that after the object is stressed, the original configuration surface can still To maintain a plane, this force is called torsion, and its cross-section can be used to judge whether it is pure twist or warp.

Problems solved by technology

[0004] The torque will cause inaccurate processing strokes of the injection molding machine tools on the machine base, resulting in an imbalance in the accuracy of the processed object. The injection molding machine has a long injection tube, and after the torsional deformation of the machine base, the injection tube will be brought into close contact. There is a slight deviation in the injection position of the module, which causes problems with the injection material; or when the two modules slide to match the mold, there is a slight angle offset caused by the torsion of the machine base, which makes it impossible to accurately close the mold , resulting in the failure of mold clamping and the consequences of poor products
