Further, in step S01, adopt the volume of fluid-discharge therapy Measurement die.
Further, in step S02, adopt container to contain and get test material.
Further, container is the measurer with volume scale.
Further, die cavity method for measuring thickness be also included in step S1 before pre-treatment step, pre-treatment step comprises and being coated on the surface of die cavity by plastic sheeting.
Further, in pre-treatment step, plastic sheeting is two, a covered rearing with plastic film on the upper surface of drag box, another plastic sheeting be coated on cope towards on the surface of drag box side.
Further, the thickness of vernier caliper measurement test material is adopted.
Apply technical scheme of the present invention, step S1: in drag box, place test material; Step S2: be fastened on by cope on drag box, is extruded to make test material and extends in die cavity; Step S3: cope is removed; Step S4: test material is taken out by drag box; Step S5: the thickness measuring test material, the thickness of test material equals the thickness of die cavity.Owing to putting into test material in die cavity, and make the surface in test material ecad chamber by pressure and extend in die cavity, therefore by measuring the thickness after the distortion of test material, just directly can obtain the thickness of die cavity, thus make die cavity thickness have the advantages that easily measure, and then can repair die cavity inwall according to die cavity thickness, ensure the wall thickness of cast article.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 shows the structural representation of cope, drag box and die cavity in the present invention.
Wherein, above-mentioned accompanying drawing comprises the following drawings mark:
10, drag box; 20, cope; 30, die cavity.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
In order to solve the problem in prior art, the thickness of near closed hollow ring being difficult to measurement, the invention provides a kind of die cavity method for measuring thickness.
As shown in Figure 1, die cavity method for measuring thickness comprises step S1 to step S5, wherein, and step S1: place test material in drag box 10; Step S2: be fastened on by cope 20 on drag box 10, is extruded to make test material and extends in die cavity 30; Step S3: cope 20 is removed; Step S4: material will be tested and take out by drag box 10; Step S5: the thickness measuring test material, the thickness of test material equals the thickness of die cavity 30.
Owing to putting into test material in die cavity 30, and make the surface in test material ecad chamber 30 by pressure and extend in die cavity 30, therefore by measuring the thickness after the distortion of test material, just directly can obtain the thickness of die cavity 30, thus make die cavity thickness have the advantages that easily measure, and then can repair die cavity inwall according to die cavity thickness, ensure the wall thickness of cast article.
Preferably, the thickness of vernier caliper measurement test material is adopted.
Certainly, miking can also be adopted to test the thickness of material.
Test material in the present invention is plastic material.Significantly distortion can be produced under external force due to plastic material and can not be destroyed, therefore, ensureing that test material can keep definite shape after extrusion, and can continue to change shape under other External Force Actings, have the advantages that to reuse.
Preferably, testing material is plasticine, pottery mud or dough.It should be noted that, though be plasticine, pottery mud or dough in use, all to ensure that its humidity should be too not large, be difficult to remove with the surface avoiding test material to be bonded in die cavity 30, avoid being difficult to remove test material, or in the process removing test material, change the shape of test material, avoid inaccurate to the thickness measure of test material, error is excessive.
Die cavity method for measuring thickness in the present invention be also included in step S1 before pre-treatment step, pre-treatment step comprises step S01 and step S02, wherein, step S01: the volume of Measurement die, mould be used for forming recess 30; Step S02: according to the volume size of mould, measures the equal-sized test material with mould volume, for subsequent use.
Specifically, in step S01, adopt the volume of fluid-discharge therapy Measurement die.Certainly, mould can also be placed on and fill in the measurer of solution, observe the liquid level change of liquid level in measurer, to record the volume of mould.
In step S02, adopt container to contain and get test material.Specifically container is the measurer with volume scale.When adopting the measurer with volume scale to contain to get test material, when test the Sheng of material get bulking value reach scale shown in mould volume time, now stop Sheng getting, make test material for subsequent use.
In order to avoid test material and die cavity 30 inwall adhesion, therefore die cavity method for measuring thickness be also included in step S1 before pre-treatment step, pre-treatment step comprise plastic sheeting is coated on die cavity 30 surface on.By the surface coverage plastic sheeting at die cavity 30, to make the surperficial indirect contact of test material and die cavity 30, thus provide convenience for taking out test material.
In order to improve the measuring accuracy of die cavity 30 further, it should be noted that the thickness of test material adds that the thickness of plastic sheeting is only the thickness of die cavity.
Specifically, in pre-treatment step, plastic sheeting is two, a covered rearing with plastic film on the upper surface of drag box 10, another plastic sheeting be coated on cope 20 towards on the surface of drag box 10 side.
Die cavity method for measuring thickness in the present invention is specially adapted to measure near closed hollow ring 30.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
