摘要

PURPOSE: A manufacturing method for a pot of an elastic pad is provided to reduce the labor load of workers, to promote the convenience on works, to improve productivity by shortening the working hours, and to reduce the cost of product by simplifying the accessory equipment required for manufacturing a pot and reducing the cost required for manufacturing a pot. CONSTITUTION: The manufacturing method for a pot of an elastic pad comprises the steps of: manufacturing a pot body(111) provided with a slide fitting groove(111a) and a cylinder groove using metal; placing/fixing the pot body(111) on a core(21b) of a lower die(21) to fix a core(21b) of a lower die(21) to a cylinder groove of the pot body(111), then installing an outer frame(23) to a die base(21a) of the lower die(21), then placing/fixing the pot body(111) to the core(21b) of the lower die(21) to fix the core(21b) of the lower die(21) to the cylinder groove of the pot body(111); placing liquefied coating materials(CM) to a gap among the lower die(21), the assembling outer frame(23) and the pot body(111) using a covering materials injection device(40); hardening the coating materials(CM) for an appointed time; removing the outer frame(23); separating a semimanufactured pot from the lower die(21); and attaching sealing materials around the slide fitting groove(111a) of the separated semimanufactured pot.
