Rotating disc structure of movable template of injection molding machine

Abstract

The invention relates to a rotating disc structure of a movable template of an injection molding machine, and the rotating disc structure comprises a baseplate, a rotating shaft arranged at the center of the baseplate in a penetrating manner, a rotating disc and a driving mechanism for driving the rotating disc to rotate, wherein the rotating disc is connected with the rotating shaft and can rotate relative to the baseplate, linkage teeth are arranged on the edge of the baseplate and used for driving the rotating disc to do rotation motion, a regulating top plate is arranged at the bottom end of the baseplate and fixed through a screw, a regulating screw is arranged at the upper end of the regulating top plate, a regulating seat plate is arranged between the regulating top plate and the rotating disc, a bearing is movably connected to the regulating seat plate, an outer ring of the bearing is provided with a bearing sleeve and is in contact with the circumferential surface of the bottom of the rotating disc, a pressure plate is buckled and connected to the bearing sleeve, and the regulating seat plate is connected with the bearing through a screw. The rotating disc structure has the advantages of simple structure, economical efficiency, practicality, high precision, energy conservation, long service life and the like.

Description

technical field [0001] The invention relates to a turntable structure, in particular to a turntable structure of an injection molding motorized template. Background technique [0002] At present, the existing turntable structure is supported by a cantilever beam. When it is applied to a horizontal injection molding machine, it is often necessary to inject a large-tonnage mold, which is heavy and bulky, and the weight of the turntable itself is relatively large, which will make the entire turntable The load increases, and such a large load will cause the turntable to deflect in the vertical plane, which will reduce the mold clamping accuracy and reduce the service life of the turntable; generally, the existing turntable rotation indexing structure is more complicated, and the form There are many kinds, the amount of parts processing and assembly is large, and water leakage often occurs, which not only wastes resources, but also pollutes the environment; while the turntable ge...

The positioning accuracy of repeated rotation is not high, which affects the accuracy of mold clamping and also reduces the service life of the mold
