Abstract
The invention relates to a ceramic central spindle moulding mould, which is characterized by comprising a hydraulic device, wherein the hydraulic device is internally provided with a fixed die tube which is provided with a pressure port; a soft die is arranged in the fixed die tube; powder is fed into the soft die through a feeding device; an upper die-set is arranged above the soft die; a metal end socket and a metal core pin are arranged on the upper die set; and a driving device drives the upper die set to go up and down. The other technical scheme of the invention provides a method for moulding a ceramic shaft by a dry type isostatic pressing process, which is characterized by comprising the following steps: feeding the powder into the soft die through the feeding device; moving down the upper die set; pressing the metal core pin into the soft die; tightly closing the upper port of the soft die by the metal end socket; driving a piston to pressurize a hydraulic cylinder through a side piston; and applying pressure on the soft die through the pressure port of the fixed die tube by the hydraulic medium so as to press the powder in the soft die into a bisque and then decompressing. The invention has high production efficiency, reduces the labor force and realizes self loading.
Description
Technical field
The present invention relates to a kind of ceramic shaft core mould and use the method for a kind of dry type isostatic pressing process forming ceramic axle of this mould.
Background technology
The moulding process of ceramic shaft core generally adopts hot die-casting molding technology and two kinds of methods of wet type isostatic compaction technology.
Though hot die-casting molding technology production efficiency is high the porosity of goods than higher, bulk density is low, influences the intensity and the qualification rate of final ceramic shaft.Topmost problem is that the goods of hot die-casting molding technology discharge a certain amount of flue dust environment is polluted in follow-up de-waxing operation.
The good product quality of wet type isostatic compaction technology institute moulding and do not discharge any pollutant in process of production, but production efficiency low (people/sky, every machine+10=4000 fulcrum cores), need a large amount of people's frock mould, stripper member, belong to labor-intensive production model.
Summary of the invention
The purpose of this invention is to provide a kind of used mould in pollution and the ceramic shaft core forming method of enhancing productivity and this method that can not produce.
In order to achieve the above object, a technical scheme of the present invention has provided a kind of ceramic shaft core mould, it is characterized in that, comprise hydraulic means, be provided with out the cover half pipe of pressure port in hydraulic means, soft mold is located in the cover half pipe, powder is sent in the soft mold by pay-off, be provided with top mold frame above soft mold, metal end enclosure reaches to the metal core bar and is located on the top mold frame, and top mold frame is driven by drive unit and rises or descend.
Another technical scheme of the present invention has provided a kind of method of dry type isostatic pressing process forming ceramic axle, it is characterized in that step is:
Move on step 1, the top mold frame,, make metal end enclosure reach the soft mold that is positioned at the below for metal-cored pole pair standard with metal end enclosure and for the metal core bar is assemblied on the top mold frame;
Move on step 5, the top mold frame, the biscuit on the metal core bar is taken down.
The present invention is mainly according to the operation principle of static pressure such as wet type, plug is fixed on the metal end enclosure on the top mold frame, rubber mold is placed in the metal cover half pipe in the hydraulic cylinder, make that rubber mold is unlikely to move arbitrarily, when top mold frame moves down by the piston cylinder driving, plug enters in the rubber mold, metal end enclosure moves down the oral area of sealing rubber mold, make hydraulic medium can not enter in the rubber mold, oil pump by horizontal piston cylinder pressurizes in hydraulic cylinder at last, to reach the purpose of compression moulding.
Advantage of the present invention is: the production efficiency height: a people one machine/sky=10000; Reduce the labour, every machine is as long as a people; Charging realizes filling automatically, guarantees the material amount unanimity in each mold cavity; Soft mold is fixed in the interior cover half pipe of hydraulic cylinder, needn't repeat to pick and place, and reduces operative employee's labour intensity greatly.
