Sponge type holding device

The invention aims at creating a sponge type holding device for the purpose of improving the molding qualified rate of a product. For achieving the purpose, the technical scheme adopted in the invention is as follows: the sponge type holding device is characterized in that a heated blank pipe (softened) is held and arranged on a die head for molding, the holding device is called as pincers, and a sponge type liner is put in the holding device, thereby solving the problem that the heated blank pipe is easy to damage or break in the holding process. The device has the advantages that the structure is simple, the manufacturing is convenient, and the molding qualified rate of the product is improved.
