the die pressing cover is detachably arranged at the upper end of the die cylinder and is provided with a pressing part which can be just embedded into the inner cavity of the die cylinder;
the die bottom cover is detachably arranged at the lower end of the die cylinder and comprises a bottom cover body part, an inner cylinder part which can be just embedded into the inner cavity of the lower end of the die cylinder is arranged on the upper surface of the bottom cover body part, a pipe body part is arranged in the center of the lower surface of the bottom cover body part, and the central cavity of the pipe body part penetrates through the upper surface of the bottom cover body part and is communicated with the inner cylinder part;
the bottom rod of the die is a rod body which can be just embedded into the central cavity of the pipe body, and the upper end of the bottom rod of the die extends into the center of the inner barrel all the time and forms an annular cavity with the inner wall of the inner barrel;
when the glass blank is manufactured, firstly, a mould pressing cover is opened, a mould is used for placing glass liquid in a mould cylinder, then the mould pressing cover is arranged, the mould pressing cover is downwards extruded, the annular cavity between a mould bottom rod and a mould bottom cover is filled with the glass liquid under the action of gravity and the extrusion of the mould pressing cover, and an annular glass blowing opening positioned in the mould bottom cover is formed at the lower end of the glass blank in the process of gradually solidifying the glass liquid into the glass blank; then, the mold bottom cover is pulled out together with the glass preform, and is inverted by 180 degrees, so that the mold bottom cover is arranged above, the glass preform is arranged below, and the glass preform which is not completely solidified and still has plasticity is gradually stretched under the action of gravity to form a glass preform which is long and narrow and has a glass blowing opening.
5. The manufacturing process according to claim 4, wherein: the mould bottom cover is directly used as a blowing pipe of the blowing mould, the bottom cover body part of the mould bottom cover is matched with the communication cavity of the blowing mould, the bottom cover body part can be just embedded into the outer port of the communication cavity to form sealing fit, the inner barrel part extends into the communication cavity, and the pipe body part is positioned outside the blowing mould;
