Embodiment 1

[0028] refer to Figure 1-2 As shown, the present invention discloses a molding equipment for ultra-high molecular weight polymer special-shaped parts with controllable orientation, including: a movable mold module 1 and a fixed mold module 2; the movable mold module 1 includes a vibration driving mechanism 11 and a movable mold 12; The movable die 12 is fixedly connected to the bottom end of the vibration drive mechanism 11; the fixed die module 2 includes a fixed die 21, two fixed die drive mechanisms 22 and two forming mechanisms 23; the upper end of the fixed die 21 is provided with a forming groove 211 with an upward opening. , and its outer side wall is provided with a through hole 212 matching the molding mechanism 23 ; the fixed mold 21 is located below the movable mold 12 ;

[0029] The molding mechanism 23 is a mold core 231 ; each mold core 231 is correspondingly disposed in a through hole 212 , and one end of the mold core 231 away from the molding groove 211 is fi...

Embodiment 2

[0041] refer to image 3 As shown, the present invention discloses another ultra-high molecular weight polymer shaped part forming equipment with controllable orientation.

[0042] In this embodiment, the forming mechanism 23 is a mechanism composed of a limit block 231 ′ and a slider 232 ′; the limit block 231 ′ and the slider 232 ′ can be slidably arranged in the through hole 212 ; the slider 232 ' is closer to the forming groove 211 than the limit block 231'; one end of the limit block 231' away from the forming groove 211 is fixedly connected to the output end of the fixed die drive mechanism 22; There are two; two limit blocks 231 ′ and two sliding blocks 232 ′ are symmetrically arranged in the through holes 212 on both sides of the fixed die 21 , and the other structures are the same as those of the first embodiment.

[0043] Forming method: a. The driving device 221 drives the limiting block 231' to move to the inside of the forming groove 211, thereby driving the slid...

Abstract

The invention discloses an ultra-high molecular weight polymer special-shaped part forming equipment with controllable orientation, comprising a movable mold module and a fixed mold module; the movable mold module includes a vibration driving mechanism and a movable mold; the movable mold is fixedly connected to the vibration driving mechanism the bottom end; the fixed mold module includes a fixed mold, several fixed mold driving mechanisms and several forming mechanisms; the upper end of the fixed mold is provided with a forming groove with an upward opening, and the outer side wall of the fixed mold is provided with a through hole matching the forming mechanism; The fixed mold is located below the movable mold. The present invention can control the orientation direction and orientation degree of ultra-high molecular weight polymer molecular chains by controlling parameters such as the reference load, amplitude, frequency and other parameters of the vibration pressure of the moving die to which the melt is subjected, or the moving direction and distance of the slider, thereby effectively improving the polymer chain. At the same time, by controlling the temperature of the fluid in the temperature control flow channel and accurately controlling the temperature in the molding tank, it ensures the stability of the molding process of the ultra-high molecular weight polymer special-shaped parts and improves the molding quality of the parts.

Description

technical field [0001] The invention relates to the technical field of ultra-high molecular weight polymer molding, and more particularly to a device for forming an ultra-high molecular weight polymer special-shaped part with controllable orientation. 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) and ultra-high molecular weight polytetrafluoroethylene (PTFE). The molecular weight of UHMWPE usually exceeds 1.5 million g / mol. 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, there are currently more than 3 million implantation operations for UHMWPE artificial joints around the world every year, and with the prolongation of the av...
