Abstract

The invention discloses an injection mold fixture for a plastic coating of an internal spline guide rail of a gear shaper, which comprises a base, a lower pressing cover, a positioning base, an internal tooth mold cover, an upper pressing cover and a main shaft, wherein, the base is used for placing the internal spline guide rail to be injected; the low pressing cover is fixed with the internal spline guide rail to be molded; the positioning seat is fixed on the bottom of the main shaft; the upper pressing cover sleeves the main shaft, and the lower part of the upper pressing cover is pressedinto the internal spline guide rail to be molded; the inner tooth mold cover sleeves the spline of the main shaft, and the inner tooth mold cover, the main shaft, the positioning seat and the inner spline guide rail to be molded form an injection molding space. The injection mold fixture of the invention realizes the injection molding requirement of the spline guide rail in the gear shaper, improves the wear-resisting and shock-proof effect of the spline guide rail, and further improves the precision and efficiency of the gear shaper.

Description

technical field [0001] The invention belongs to the technical equipment field and is used for plastic coating injection molding of inner spline guide rails in gear shaping machines. Background technique [0002] With the continuous development of the gear processing industry, the requirements for gear shaping machines are also getting higher and higher. The internal spline guide rail is the core of the gear shaping machine. If its accuracy and work efficiency can be improved, the overall efficiency and accuracy of the gear shaping machine can be effectively improved. Now the internal spline guide rail adopts HNT plastic coating, which can increase the stroke of the tool spindle from 800 times per minute to 1700 times per minute, which is a great improvement for the gear shaping machine. Such as figure 1 As shown, the hatched part in the figure is the plastic coating 8 of the inner spline guide rail, which needs to be injected on the inner spline wall. However, the require...
