Description

Technical Field

[0001] The utility model belongs to the technical field of hot pressing forming tooling, and particularly relates to a hot pressing forming tooling with a switchable series of modules. Background Art

[0002] When testing the tensile strength, hardness, dielectric strength and other properties of adhesives, it is necessary to prepare test specimens of adhesives. At present, for the preparation of test specimens of adhesives of types such as polyurethane and epoxy, the method of using a silicone mold in cooperation with a scraper is usually adopted. The adhesive is loaded into the forming groove of the silicone mold, and then the adhesive on the top and bottom surfaces is scraped off by using the scraper, so as to form test specimens such as dumbbell-shaped splines, hardness blocks, and square blocks with different thicknesses of 100mm×100mm, and then put into an oven at a corresponding temperature for heating and forming. Most of such products are two-component mixtures. After being mixed evenly, air bubbles will be removed. However, stacking will occur during the process of introducing the specimens, and the air bubbles will be wrapped inside. Therefore, problems such as air bubbles, deformation and uneven sample surface are likely to occur. If the adhesive on the top and bottom surfaces is scraped off by using a scraper, the air holes will be exposed, causing a certain degree of damage to the specimens, and at the same time, it will also lead to large errors in the measured data.
