Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] see Figure 1-15 , a polymer hot-press mold with a variable cavity, including an upper male mold 1, a female mold 2, and a lower male mold 6. The female mold 2 has a cavity that runs through up and down, and the upper and lower parts of the cavity are respectively connected to the upper male mold. 1 is matched with the lower male mold 6, and it is characterized in that: the hot pressing mold is a cuboid as a whole, and the upper male mold 1 and the lower male mold 6 are rectangular parallelepiped convex platforms; the female mold 2 is a hollow cuboid up and down, and the inner cavity The cross-section of the body is rectangular, and the upper part of the cavity has a rectangular groove that is 6-10 mm longer than each side of the cavity and 25-40 mm deep from the upper mouth of the female mold 2. It is precisely matched with the boss of the upper male mold 1, an...
