MANUFACTURING APPARATUS OF RESIN BOOT FOR CONSTANT-VELOCITY UNIVERSAL JOINT AND METHOD OF MANUFACTURING RESIN BOOT FOR CONSTANT-VELOCITYUNIVERSAL JOINT, AND RESIN BOOT FOR CONSTANT-VELOCITY UNIVERSAL JOINT |
摘要 |
There is disclosed a manufacturing apparatus and method which are capable of smoothly removing a tripod boot integrated by secondary molding from a core without deforming the boot and which are superior in manufacturing efficiency and which are inexpensive, and a resin boot for a constant-velocity universal joint. The apparatus includes: divided molds which hold a primarily molded resin boot main body from the outside; a core which holds the boot main body from the inside; a runner mechanism which injects/charges a molten resin material into a secondary molding space formed between the core and an other-end annular fastening portion; and an ejection mechanism for removing the tripod boot in which portions having different thicknesses are integrally and secondarily molded on an inner periphery of the other-end annular fastening portion from the core. The ejection mechanism is provided with a plurality of ejectors in positions avoiding gates of the runner mechanism, and ejecting forces are applied onto lower end surface of the other-end annular fastening portion of the tripod boot from the ejectors to stably and smoothly remove the tripod boot from the core.
