Abstract
The utility model relates to a compound moulding die structure by extruding and forging, which is suitable for processing metal or alloy artificial knee joint platforms and forge pieces for femur condyles of artificial knee joints via the compound moulding process by extruding and forging. The die is composed of a lower die sleeve, a lower die and a lower die cushion, wherein the lower die sleeve is a ring structure seated on the lower die cushion; the lower die with a tapered outer circumference surface is sheathed in the lower die sleeve and is slightly automatically locked with the inner surface of the lower die sleeve; the center of the lower die is provided with a concave die cavity of which the bottom center is provided with a knockout hole communicated with the center hole of the die cushion by vertically penetrating through the bottom end surface of the lower die. When a forge piece is provided with a positioning ribbed plate and other complex structures, the lower die can be combined up by 2-4 separate modules as required. When the forge piece has a simple shape, the lower die can be a single structural member and can be combined with the lower die sleeve into an integral structure at the same time. Due to the adoption of the die structure, the forge piece simultaneously has the forming characteristics of extruding and forging processes. After the forming process is ended, the forge piece can be directly pushed out by a push rod. The utility model has the advantages of simple and convenient operation for forging process, and high efficiency.
Description
Technical field
The utility model is a kind of composite molding mould structure that squeezes, forges, be applicable to adopt and squeeze, forge composite molding technique processing metal or alloy artificial knee joint platform and artificial knee joint condyle of femur forging, it is a kind of mould of special use, belong to manufacture technology field of medical appliance, it relates to the improvement and the raising of existing product performance and quality, and can obviously reduce the manufacturing cost of this series products.
Background technology
Present employed artificial knee joint generally is cobalt alloy and titanium alloy casting, and high-grade forging matter titanium alloy artificial knee joint will adopt machining center production.The mechanical performance of foundry goods is lower than forging comprehensively.Into human body can be brought some gases or impurity in cavity in the foundry goods, and diffuses out at leisure, and human body is produced some bad influences.Adopt machining center production to forge the matter artificial knee joint, equipment has high input, processing charges height, incompatibility domestic market.
In addition, in international standard, banned use of the titanium alloy casting implant into body,, reduced the generation of postoperative complications to improve patient's postoperative life quality.So the development of titanium alloy artificial knee joint FMT is an inexorable trend.
According to statistics, only in the U.S., nineteen ninety, the titanium alloy artificial knee replacements just has more than 20 ten thousand examples, and thereafter with the speed increase more than 10%; At home, also more than 200,000 examples, market prospects are tempting for annual knee prosthesis case.
So, adopt and squeeze, forge the emphasis that composite molding technique processing metal or alloy artificial knee joint platform and artificial knee joint condyle of femur forging are present this area researches.Existing squeezing in the forging composite molding technique, extruding and forging molding carry out successively, and the process that puts forward is at present simultaneously finished the processing of this product in a press stroke.This technical matters is different from rammer-crowded composite forming technology again, because its Forging Technology is not the process of a simple cylinder jumping-up, and will form comparatively complicated profile.This technical staff's technology has solved the difficult point in domestic, international this product processing of present puzzlement, particularly at domestic actual conditions, can be when not improving processing charges, produce and meet that international standard is that require, high-quality titanium alloy artificial knee joint forging products, the corner on the market status of having broken external this product.
In order to guarantee the realization of above-mentioned process, just must design the novel mould of a cover and form and structure, it should satisfy the forming requirements that forging realizes pushing and forging processing simultaneously, and need be simple to operation, has higher production efficiency.
Summary of the invention
The purpose of this utility model designs crowded, the forging composite molding mould structure that a kind of new structure is provided just at above-mentioned situation, in process, need the blank after the heating is put into same through the composite die after the heating, and apply certain pressure forming, adopt mould structure of the present utility model, can forge the artificial knee joint precision die forgings.Thereby reduce the production cost of forging the matter artificial knee joint,, improve patient's postoperative life quality, reduce the generation of postoperative complications to substitute the cast product of artificial knee joint.It is a kind of precision die forging production technology particular manufacturing craft structure of new artificial knee joint.
The purpose of this utility model realizes by following measure:
This kind squeezes-forges the composite molding mould structure, be applicable to adopt and squeeze, forge composite molding technique processing metal or alloy artificial knee joint platform and artificial knee joint condyle of femur forging, its structural design features is, this mould is by lower die-sleeve, counterdie and following die-cushion are formed, lower die-sleeve is a circulus, seat is contained in down on the die-cushion, the outer circumference surface of counterdie is a taper, be sleeved in the lower die-sleeve and form slight self-locking with the inner surface of lower die-sleeve, be processed with one at the center of counterdie and be concave die cavity, the bar portion die cavity position of concave die cavity is through hole and penetrates the counterdie formation jogger hole that is connected with the centre bore of following die-cushion.When labyrinths such as part forging band location floors, and when being not easy to eject depanning, counterdie can be formed by 2～4 lobe somatotype module combinations as required.And when the forging simple shape, and when being easy to eject depanning, counterdie can be monomer structure spare, and this moment, it can constitute integral structure with lower die-sleeve.
