Abstract

The invention provides a rolling polishing device for a 45-degree parting surface sealing rubber ring mold. The rolling polishing device comprises a cutter bar, a steel ball, a pressing block and a pressing screw, wherein the head of the cutter bar is provided with a hole, and a 45-degree angle is formed between the hole and the length direction of the cutter bar; the pressing block is installed in the hole through the pressing screw and a pressing plate; the front end of the pressing block is provided with a V-shaped groove; one half of the steel ball gets stuck in the V-shaped groove. A polishing process with the rolling polishing device for the 45-degree parting surface sealing rubber ring mold comprises the steps that the cutter bar is clamped to a cutter holder of a lathe; the steel ball with the diameter equaling that of a mold cavity is put in the annular mold cavity; and glycerin for lubricating is painted in the V-shaped groove of the pressing block, the steel ball is pressed through the pressing block, the lathe is started, and the steel ball rolls in the annular mold cavity along with rotation of the rubber ring mold, so that rolling and polishing of the annular mold cavity are achieved. The rolling polishing device and process for the 45-degree parting surface sealing rubber ring mold have the advantages that the rolling and polishing effects are good, the luminosity is rapidly improved, the dimension consistency of the mold cavity is good, and a sharp edge is not damaged; in addition, the mechanical strength of the surface of the mold cavity can be improved, and the effect is more obvious when the mold is large.

Description

technical field [0001] The invention relates to the field of cavity surface polishing, in particular to a rolling polishing device and process for a 45° parting surface sealing rubber ring mold. Background technique [0002] The roughness of the cavity surface of the plastic model is required to reach Ra0.2. For the "O" type sealing rubber ring mold, when the parting surface is flat, the cavity is generally polished by steel ball rolling. However, when the parting surface is 45°, the above method cannot be used because the steel ball is easy to break out of the cavity. The polishing of this type of plastic mold has always been done manually. The polishing efficiency is low and the labor intensity is high. Contents of the invention [0003] The purpose of the present invention is to improve the cavity surface quality, dimensional accuracy and polishing efficiency of the "O" type sealing rubber ring mold with 45° parting surface, and specially provides a rolling polishing d...
