Abstract
The invention discloses a sintering fixture for a surgical knife handle formed by injecting metal powder. The sintering fixture comprises a first fixture, a second fixture and a third fixture, wherein twelve grooves are uniformly distributed in the surface of the first fixture; the second fixture is a pellet fixture; and the first fixture is fixedly connected with the second fixture through the third fixture. Due to the adoption of the mode, according to the sintering fixture disclosed by the invention, the sintering breaking, bent deformation, displacement and the like of surgical handle products formed by injecting the metal powder can be effectively prevented; the part placing work becomes simple; the more-orderly storage of products is realized, field management is facilitated and the production efficiency can be greatly increased.
Description
Technical field
The present invention relates to the metal powder injection molding technical field, particularly relate to a kind of metal powder injection molding knife handle and use the sintering tool.
Background technology
The metal powder injection molding technology is a kind of novel manufacturing process technology that powder metallurgy is combined with plastics forming technique.
It is earlier selected powder to be mixed with binding agent, then with the compound needed shape of injection moulding again of granulating.Polymer is given compound with the characteristic of its VISCOUS FLOW, and help to be shaped, die cavity is filled and the uniformity of powder packing.Binding agent is got rid of in moulding later on, again the degreasing base is carried out sintering.
But product a little less than especially after removing binding agent, being highly brittle, can produce fracture, flexural deformation, displacement etc. especially, thereby cause scrapping of product before sintering.
Because the product quantity of knife handle is many, and the plane that can directly place of neither one, sintering is to need fixedly placing attitude, needs the labor manpower that product is correctly put one by one, has reduced production efficiency.
In order to address the above problem, to have designed a kind of sintering tool of uniqueness and placed the knife handle product.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of metal powder injection molding knife handle that can be used in circulation and uses the sintering tool; Can effectively prevent the problems such as sintering fracture, flexural deformation, displacement of metal powder injection molding knife handle product, can significantly enhance productivity simultaneously.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: provide a kind of metal powder injection molding knife handle to use the sintering tool; Comprise: first tool, second tool and the 3rd tool; The first tool surface is evenly distributed with 12 grooves, and second tool is the saddle tool, and first tool is fixedly connected through the 3rd tool with second tool.
In preferred embodiment of the present invention, the profile of said first tool, second tool and the 3rd tool all is rectangle.
In preferred embodiment of the present invention, the specification of said first tool is 175mm*84mm*6mm, and the specification of second tool is 176mm*26mm*3.9mm, and the specification of the 3rd tool is 11mm*1.5mm*1mm,
In preferred embodiment of the present invention, the specification of said groove is 84mm*1.6mm*1.4mm.
In preferred embodiment of the present invention, the size of the degree of depth of said groove and width and knife handle is equipped with.
In preferred embodiment of the present invention, said first tool is provided with 12 knife handles.
In preferred embodiment of the present invention, said first tool, second tool and the 3rd tool adopt aluminium oxide ceramics to process.
The invention has the beneficial effects as follows: metal powder injection molding knife handle of the present invention can effectively prevent problems such as the sintering fracture, flexural deformation, displacement of metal powder injection molding knife handle product with the sintering tool; Guarantee that goods of furniture for display rather than for use work becomes simple; Depositing of product is more in good order; Help on-the-spot pipeline, can significantly enhance productivity.
Description of drawings
Fig. 1 is the structural representation of metal powder injection molding knife handle of the present invention with one preferred embodiment of sintering tool;
Fig. 2 is that the A-A of first tool among Fig. 1 is to cutaway view;
The mark of each parts is following in the accompanying drawing: 1, first tool, 2, second tool, the 3, the 3rd tool, 4, groove.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 to Fig. 2, the embodiment of the invention comprises:
A kind of metal powder injection molding knife handle is used the sintering tool, comprising: first tool 1, second tool 2 and the 3rd tool 3, the first tools 1 are fixedly connected through the 3rd tool 3 with second tool 2.
The profile of said first tool 1, second tool 2 and the 3rd tool 3 all is rectangle.Particularly, the specification of first tool 1 is 175mm*84mm*6mm, and the specification of second tool 2 is 176mm*26mm*3.9mm, and the specification of the 3rd tool 3 is 11mm*1.5mm*1mm.
The upper surface of said first tool 1 is used for fixing the knife handle product.First tool, 1 surface is evenly distributed with 12 grooves 4, can put 12 knife handle products.
Groove 4 its degree of depth that on first tool 1, are provided with and the size of width and knife handle are equipped with.Particularly, the specification of groove 4 is 84mm*1.6mm*1.4mm.Groove 4 designs can prevent that knife handle from occuring bending and deformation in sintering process.
Said second tool 2 is the saddle tool, is used to support the knife handle product, can prevent that fracture and displacement take place product in the sintering process, has improved production efficiency.
Said first tool 1, second tool 2 and the 3rd tool 3 adopt aluminium oxide ceramics to process, and the high temperature in can anti-metal injection molded sintering process guarantees the sintering quality of product.
Metal powder injection molding knife handle of the present invention with the course of work of sintering tool is:
The knife handle product that removes the binding agent completion is positioned on the sintering tool one by one, places 12 knife handle products on each tool, put the sintering tool of product and directly put into the vacuum drying oven sintering.
Among the present invention, the width of first tool, 1 upper groove 4 and the degree of depth and knife handle product are consistent, and second tool 2 is the saddle tool, the fracture that can place product, and the 3rd tool 3 is used for fixing first tool 1 and second tool 2.So, the knife handle product is sintering finished can not to rupture during to metallic state, flexural deformation and goods of furniture for display rather than for use displacement, thereby can obtain qualified product, helps the dimensional accuracy of metal injection molded knife handle.
Metal powder injection molding knife handle of the present invention with the beneficial effect of sintering tool is:
