Abstract
The utility model discloses a kind of cold edge mould for making metallographic specimen, including external mold and base, it is characterised in that：External mold is fixedly installed on the upper end of base, and bottom plate is located at external mold intracavitary bottom, and push rod is fixed with the bottom panel of bottom plate, and push rod is rotatablely connected by the inner end of rotating shaft and handle, and the outer end of handle passes through the through hole on base side wall.The utility model is simple in construction, easy to operate, can not only reuse, reduce material consumption, reduces solid waste pollution, and facilitates in sample from mould and take out, and reduces sample preparation difficulty, reduces the consumption of the sample preparation consumptive material such as sand paper.
Description
Technical field
A kind of metallographic sample preparation aid is the utility model is related to, specifically a kind of cold edge for making metallographic specimen
Mould.
Background technology
Metallographic detection is one of important detection and analysis means of metallurgy industry, to carry out metallographic detection and first have to carry out sample preparation
Work, according to GB/T 13298-2015《The metal microstructure method of inspection》It is required that specimen size is smaller（Such as thin plate, silk ribbon
Material, tubule etc.）, sample it is excessively soft, frangible, specimen shape is irregular, examine edge tissues, be standardized for Automatic Grinding Prototype
The samples such as sample preparation need to inlay.According to being actually needed, cast setting method can be selected or resin inlaying process is inlayed, wherein resin is inlayed
Method mainly includes hot edge method and cold edge method.
To temperature and pressure, sensitive material will carry out cold edge, and cold edge material has polyester resin, acrylic resin, asphalt mixtures modified by epoxy resin
Fat etc., it is possible to use dental base acrylic resin powder and dental basse acrylic resin liquid, cold edge mould can use hard rubber, polytetrafluoroethylplastic plastic, carton etc..During cold edge,
Sample detection is put into suitable cold edge mould down, and resin and curing agent are sufficiently stirred by proper ratio, inject mould,
It is molded in cold curing.
Metallographic sample preparation is carried out using conventional cold edge mould to have the following disadvantages：First, conventional cold edge mould is disposable mould
Tool, can not be reused, cause the wasting of resources, and organic process is difficult to after, cause environmental pollution；Second, using normal
Advise after cold edge mould inlays, the typically more difficult sample from mould that will inlay is taken out, it is necessary to ground with mould, sample is ground face
Product increases, and wastes consumptive material, while because sample becomes thick, also increase the difficulty of grind away human hand held sample.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, easy to operate, you can reuses, is easy to take out again
The cold edge mould of the making metallographic specimen of metallographic sample.
In order to reach object above, technical scheme is used by the utility model：This is a kind of to make metallographic specimen
Cold edge mould, including external mold and base, it is characterised in that：External mold is fixedly installed on the upper end of base, and bottom plate is located at external mold intracavitary
Bottom, push rod is fixed with the bottom panel of bottom plate, push rod passes through the inner end of rotating shaft and handle and is rotatablely connected, the outer end of handle
Portion passes through the through hole on base side wall.
Described external mold, cylindrical, its internal diameter is 30mm, external diameter 32mm, is highly 32mm, inner wall smooth；It is described
Base, cylindrical, its external diameter is 32mm, internal diameter 26mm, is highly 60mm；Described bottom plate, rounded, its external diameter is
30mm, thickness 2mm.
The beneficial effects of the utility model are：It is simple in construction, easy to operate, it can not only reuse, reduce material
Material consumption, reduces solid waste pollution, and facilitates in sample from mould and take out, and reduces sample preparation difficulty, reduces sand paper
Deng the consumption of sample preparation consumptive material.
Brief description of the drawings
Fig. 1 is structure schematic cross-sectional view of the present utility model.
In figure：1st, external mold；2nd, bottom plate；3rd, base；4th, handle；5th, through hole；6th, push rod；7th, rotating shaft.
Embodiment
Reference picture 1 makes the utility model.A kind of cold edge mould for making metallographic specimen, including external mold 1 and base
3, it is characterised in that：External mold 1 is fixedly installed on the upper end of base 3, and bottom plate 2 is located at the intracavitary bottom of external mold 1, the bottom panel of bottom plate 2
On be fixed with push rod 6, push rod 6 is rotatablely connected by the inner end of rotating shaft 7 and handle 4, and the outer end of handle 4 passes through base 3
Through hole 5 in side wall.
Described external mold 1, cylindrical, its internal diameter is 30mm, external diameter 32mm, is highly 32mm, inner wall smooth；It is described
Base 3, cylindrical, its external diameter is 32mm, internal diameter 26mm, is highly 60mm；Described bottom plate 2, rounded, its external diameter
For 30mm, thickness 2mm.
During using the utility model, the sample for preparing to inlay is placed on the bottom plate 2 in the inner chamber of external mold 1, sample detection faces
It is vertical downwards to place, then inlay deployed in proportion is added in the inner chamber of external mold 1, paid attention to not during the cold edge material of addition
Sample is set to be moved or tilt, cold edge material at most must not exceed the upper edge of external mold 1, then wait inlay solidification.Inlay
After material solidification, handle 4 is pressed downward, handle 4 drives push rod 6 and bottom plate 2 upward using the lower edge of through hole 5 as fulcrum, using lever principle
It is mobile, sampling work is completed, because of the inner wall smooth of external mold 1, slight shrinkage occurs in condensation process for inlay so that inlay connects
It is removed with one piece of the sample inlayed, grind away work is carried out after taking-up.
