The detection bottom plate 13 and the sample piece can be directly moved, so that the sample piece can be conveniently moved to a specified position for detection, and the time for waiting for the solidification of the non-solidified rubber material is effectively shortened.
The embodiment has the following advantages:
the die orifice 15 is arranged on the die frame 14, the die frame 14 is placed on the detection bottom plate 13, the detection bottom plate 13 blocks the lower end of the die orifice 15 of the pipe penetrating die frame 14, and therefore when non-cured rubber materials are poured into the die orifice 15, the non-cured rubber materials can be in contact with the detection bottom plate 13, and sample pieces formed after the non-cured rubber materials are solidified can be located on the upper surface of the detection bottom plate 13. After the non-cured rubber material is poured into the die orifice 15 and is cured, the length and the width of the cured sample piece can be the same as those of the die orifice 15, and then the die orifice 15 with a proper size can be arranged on the die frame 14, so that the size of the sample piece is ensured to meet the test requirement, the size error of the sample piece is small, and the appearance quality of the sample piece is improved.
In the process of pouring the non-solidified rubber material into the die orifice 15, one end of the sample preparation supporting plate 11 is lifted, so that the sample preparation supporting plate 11 is inclined by 10-20 degrees with the horizontal plane, and the detection bottom plate 13 and the die frame 14 which are positioned on the upper surface of the sample preparation supporting plate 11 are also in a state of being inclined by 10-20 degrees. Then, non-cured rubber is slowly poured into the die orifice 15 from the upper end of the inclined die orifice 15, and the non-cured rubber flows to the lower end of the die orifice 15 from the upper end of the die orifice 15 along the surface of the inclined detection bottom plate 13, so that the non-cured rubber can quickly flow to different positions in the die orifice 15 before solidification, the length and width of the sample piece are ensured to be corresponding to the length and width of the die orifice 15, and the size of the sample piece is ensured to meet the measurement requirement. Because the die orifice 15 is in an inclined state, the non-solidified rubber material cannot fill the die orifice 15 because the height of the die frame 14 at the lower end of the die block is lower than the upper end of the die orifice 15, the non-solidified rubber material is slowly poured into the die orifice 15 and naturally leveled, so that the liquid level of the non-solidified rubber material is flush with the upper surface of the die frame 14 at the lower end of the die orifice 15, then the pouring of the non-solidified rubber material is stopped, the sample making supporting plate 11 is finally put down, the sample making supporting plate 11, the detection bottom plate 13, the die frame 14 and the die orifice 15 are in a horizontal state, more non-solidified rubber material can be contained after the die orifice 15 is in the horizontal state, the volume of the non-solidified rubber material in the die orifice 15 is unchanged, the liquid level of the non-solidified rubber material is ensured not to exceed the height of the upper surface of the die frame 14, the operation of leveling the non-solidified rubber material is not required, and the sample making process is simpler and more convenient, not only is the manufacturing of the sample piece convenient, but also the waste of the non-solidified rubber material can be reduced, and the material is saved.
After the non-solidified rubber material is poured into the die opening for 10 minutes, the die frame 14 is directly pulled out from the upper surface of the detection bottom plate 13 upwards, so that the die frame 14 is conveniently separated from the sample piece, and the effect of conveniently preparing the sample is achieved. The uncured rubber material is in a state of initial solidification (i.e., a state in which the sample is able to maintain its surface shape in a natural state) after 10 minutes, and the mold frame 14 can be easily separated from the sample. At this time, if the sample piece is cut by using the hot cutter according to the conventional method, the edge of the cut sample piece is easily deformed due to the acting force between the hot cutter and the sample piece in the cutting process. And this application need not use hot cutting knife, do not need at sample piece edge application of force when directly taking out mould frame 14, thereby can guarantee the stability of the in-process sample piece shape of mould frame 14 separation from the sample piece, can enough reduce the latency of system appearance greatly, also can play the effect of guaranteeing sample piece appearance quality, also avoided using hot cutting knife cutting unevenness and leaded to partial material to bond on mould frame 14 and unable the utilization, thereby also can reach the effect that reduces the waste of non-solidified sizing material.
