Example Embodiment
[0030] Example 1
[0031] See Figure 1~3 In the embodiment of the present invention, a mold for preparing test pieces for ablation rate, the mold includes male molds 1 on both sides, two male molds 1 are arranged in parallel, and a For the female mold 2, the two male molds 1 are connected at both ends by bolts 3, and a four-sided closed frame is formed by the two male molds 1 and one female mold 2.
[0032] The middle of the female mold 2 is provided with a number of test piece holes 4, the middle of the male mold 1 is provided with a number of protrusions 5, and the four corners of the male mold 1 and the female mold 2 are provided with bolts that cooperate with the bolts 3 Hole 6.
Example Embodiment
[0033] Example 2
[0034] In another embodiment of the present invention, the difference between this embodiment and the above-mentioned embodiment is that the male mold 1 is provided with relief grooves 7 on both sides of the edge.
[0035] A method of using a mold for preparing a test piece for ablation rate, including the following steps:
[0036] 1) Cut the test piece to be made into a shape of φ30mm×10mm, and put it into the female mold 2, a total of 6 sets of test pieces;
[0037] 2) Place the male mold 1 on the female mold 2 to ensure that the male and female molds are in good agreement;
[0038] 3) Assemble and tighten with bolt 3;
[0039] 4) Put the assembled mold into a vulcanizing box for vulcanization;
[0040] 5) After the vulcanization is over, take out the test piece and observe the outer surface of the test piece. The adhesion between the test pieces is firm without obvious delamination.
[0041] In the present invention, the steps of the prepared test piece are completely...
