Description

Technical Field

[0001] The utility model relates to the technical field of mold limiting devices, in particular to a silicone asphalt softening point detection mold limiting device. Background Art

[0002] After the modified asphalt is produced, it needs to pass the softening point test before it can be shipped out of the factory. However, the laboratory inspection volume is large, and up to 80 molds need to be cut per day. The efficiency of sample-by-sample inspection is very low, which sometimes causes delays. Therefore, it is necessary to use a suitable softening point mold limit device to reduce the process of repeated heating of the hot scraper and fixing the test piece during mold cutting, so as to achieve mold cutting of 8 samples in the same batch and improve the efficiency of softening point mold cutting.

[0003] However, in the existing equipment, the mold filled with asphalt needs to be placed in the limit hole when cutting the mold. Since the upper surface of the mold is flush with the upper surface of the limit plate, when the inspection is completed, the mold needs to be removed in sequence using tools, and the collection efficiency is low. For this reason, a silicone asphalt softening point detection mold limit device is proposed. Utility Model Content
