Embodiment Construction

[0017] Such as figure 1 As shown, the mold cavity ultrasonic machining tool of the present invention includes a taper shank 1 , an outer shell 3 , an inner sleeve 6 , a transducer 14 and a horn 11 . The shell 3 and the taper shank 1 are connected together, and the connection method can be through a threaded connection, or through other forms such as a flange. The inner sleeve 6 is set in the outer shell 3, and the front end of the inner sleeve 6 protrudes from the outer shell 3, and a spring 2 is arranged between the inner sleeve 6 and the outer shell 3 in the axial direction, so that the inner sleeve 6 can be pressed against the outer shell 3 after being subjected to axial force. internal compression, figure 1 The middle is that the spring 2 is installed between the bottom of the inner sleeve 6 and the bottom of the shell 3 . There is also a limit device when the inner cover 6 moves between the inner sleeve 6 and the outer shell 3. The limit device is to install a limit pin...

Abstract

The invention provides an ultrasonic processing tool for a mold cavity. The ultrasonic processing tool comprises a conical handle, a shell, an inner sleeve, an energy converter and an amplitude transformer, wherein the shell is connected with the conical handle; the inner sleeve is sleeved in the shell; a spring is arranged between the inner sleeve and the shell along the axial direction; a limiting device used during movement of the inner sleeve is arranged between the inner sleeve and the shell; the amplitude transformer is arranged in the inner sleeve, and is fixed through a gland connected to the inner sleeve; the front end of the amplitude transformer projects out of the inner sleeve; the energy converter is arranged at the back end of the amplitude transformer; and the front end of the amplitude transformer is provided with a spherical processing head. The ultrasonic processing tool can be directly applied to a numerical control machine tool as a cutter and is arranged on a main shaft of the applied numerical control machine tool through the conical handle, the spherical head at the front end of the amplitude transformer is contacted with the mold cavity by moving the main shaft, and the entire ultrasonic processing tool is controlled to move along the locus of the mold cavity through the machine tool, so that the ultrasonic processing of the mold cavity is finished. The ultrasonic processing tool has a simple structure, and is convenient to use; and the surface processing effect and efficiency of the mold cavity are improved.

Description

technical field [0001] The invention relates to a mold cavity ultrasonic processing tool for ultrasonic processing of a mold cavity to reduce the surface roughness value, and belongs to the technical field of mold cavity ultrasonic processing. Background technique [0002] The surface roughness of the mold cavity has a great influence on the surface quality of the molded workpiece. The surface curve of the mold cavity is complex, including planes, slopes, concaves, convexes, regular arcs and irregular arcs, usually It is a combination of multiple surfaces of different shapes. Usually, polishing is used to reduce the surface roughness value of the mold cavity. There are many types of polishing, including manual polishing, electrolytic polishing, ultrasonic polishing, extrusion honing polishing, and polishing using polishing machines. However, for mold cavities with complex shapes As for the final finishing process, manual polishing is still the main operation method at prese...
