[0002] The completion tool packer is a key tool for downhole oil production in oil fields. The packer is installed between the casing and the center pipe. When an axial load is applied to the packer rubber cylinder, the packer rubber cylinder will undergo a large radial deformation, and contact pressure will be generated between the rubber cylinder and the casing to control the fluid production and protect the casing. Therefore, the packer rubber cylinder is the core component of the packer.

[0003] The packer rubber cylinder is made of rubber raw materials that are heated at high temperature and then extruded and formed by a molding die and a jacking die. Since the packer rubber cylinder is provided with a through-hole structure, the jacking die and the molding die cooperate to extrude and shear rubber residues, which adhere to the top of the jacking die and need to be removed manually by an operator. Since the temperature of the rubber residues is relatively high, the operators need to wear thicker heat-insulating gloves for operation, resulting in inconvenient operation and low efficiency in removing the rubber residues.
