Abstract

The invention discloses orientation-controllable ultra-high molecular weight polymer special-shaped part forming equipment. The orientation-controllable ultra-high molecular weight polymer special-shaped part forming equipment comprises a movable mold module and a fixed mold module. The movable mold module comprises a vibration driving mechanism and a movable mold. The movable mold is fixedly connected to the bottom end of the vibration driving mechanism. The fixed mold module comprises a fixed mold, a plurality of fixed mold driving mechanisms and a plurality of forming mechanisms. A forming groove with an upward opening is formed in the upper end of the fixed mold, and a through hole matched with the forming mechanism is formed in the outer side wall of the fixed mold. And the fixed mold is positioned below the movable mold. By adopting the equipment, the orientation direction and orientation degree of the molecular chain of a ultra-high molecular weight polymer can be regulated and controlled by controlling the reference load, amplitude, frequency and other parameters of the movable mold vibration pressure borne by melt or the moving direction and distance of a sliding block, the comprehensive performance of a polymer special-shaped part is effectively improved, and meanwhile the temperature of fluid in a temperature control runner is controlled, so that the temperature in the forming groove is accurately controlled, the stability of the ultra-high molecular weight polymer special-shaped part forming process is guaranteed, and the part forming quality is improved.

Description

technical field [0001] The invention relates to the technical field of forming ultra-high molecular weight polymers, in particular to an orientation-controllable ultra-high molecular weight polymer special-shaped parts forming equipment. Background technique [0002] Ultra-high molecular weight polymers refer to polymers with a molecular weight of more than one million, such as ultra-high molecular weight polyethylene (UHMWPE), ultra-high molecular weight polytetrafluoroethylene (PTFE), the molecular weight of UHMWPE usually exceeds 1.5 million g / mol, and the molecular weight of PTFE The molecular weight is usually 5-10 million g / mol. Ultra-high molecular weight polymers have excellent comprehensive properties and are widely used as special-shaped parts in biomedical, aerospace, industrial transportation and other fields. For example, at present, there are more than 3 million UHMWPE artificial joint implantation operations in the world every year, and with the extension of ...
