Description

Device for producing bearing plastic retainer in batches

Technical Field

The invention relates to the technical field of bearing retainer production, in particular to a device for producing bearing plastic retainers in batches.

Background

In recent years, the development of bearings for railway vehicles has been progressing toward higher speeds, higher safety and longer life, and thus the requirements for bearing retainers have been becoming more stringent. On one hand, the bearing retainer is subjected to mechanical stress such as tension and friction, and on the other hand, the bearing retainer also needs to bear chemical corrosion of chemicals such as lubricants and organic solvents, so that the selection of the material of the bearing retainer is very important.

At present, common retainers mainly comprise metal retainers, phenolic resin retainers and plastic retainers according to different use environments. The production cost of the metal retainer and the phenolic resin retainer is high, and the processing and the assembly are complex, so that the metal retainer and the phenolic resin retainer are suitable for single-piece and small-batch production; the plastic retainer is simple to process and assemble, can be molded by a mold in one step through injection molding, and is low in cost, so that the plastic retainer can be used for large-batch industrial production.

At present, enterprises produce plastic retainers with multi-purpose injection molding machine tools, but the daily output of each injection molding machine tool is limited, and the production capacity needs to be enlarged, so that the number of the injection molding machine tools can be increased. However, a common domestic injection molding machine tool needs tens of thousands of yuan, the imported injection molding machine tool is more expensive, and the unit price of the plastic retainer is more than ten yuan and more than ten yuan, so the cost cannot be recovered when the injection molding machine tool is added.

The core components of an injection molding machine tool comprise a mold, a manipulator and a control system, wherein the mold is used for molding a plastic retainer, the manipulator is used for taking out the plastic retainer after mold opening, and the control system is used for controlling time nodes such as mold opening, mold closing, manipulator action and the like. At present, the plastic retainer needs to be produced in large batch, on the premise of saving cost, only a plurality of molds need to be arranged for simultaneous mold closing, simultaneous injection molding and simultaneous mold opening, and in addition, material taking can not be manual, and because of high labor cost and potential safety hazard, a manipulator needs to be equipped, but each mold is equipped with one manipulator, so that the production cost rises suddenly.
