[0028] The present invention has the following beneficial effects:
[0029] The present invention pours the melted medical polymer material into the interior of the extrusion frame through the feed frame, and then starts the motor to drive the rotating rod to rotate inside the extrusion frame. When the rotating rod rotates, the engagement between the cross hole frame and the limit plate drives the rotating disk to rotate. When the rotating disk rotates, the connection between the rotating rod and the round rod drives the stirring frame to rotate. The stirring frame is used to stir the medical polymer material, so that the gas in the medical polymer material can be quickly discharged, and the gas is prevented from accumulating inside the medical polymer material and affecting the molding quality. The driving ring contacts the slide plate through the slide groove. At this time, when the rotating disk rotates, the driving ring will not rotate with it. When the rotating rod rotates, the driving wheel is driven to rotate inside the driving ring, and the rotating rod is driven to rotate on the surface of the rotating disk through the driving ring, so that the stirring frame can also rotate synchronously with the rotating rod when the rotating disk rotates, so that the stirring frame can quickly press out the gas in the medical polymer material through stirring, and the electric push rod is started to push the rotating disk to move on the surface of the rotating rod, so that the rotating disk can push the medical polymer material to gather toward the center of the extrusion frame.
[0030] The circular rod of the present invention drives the circular arc plate to rotate through the extension rod when rotating, and the circular arc plate drives the cleaning rod to rotate through the connection between the telescopic frame and the elastic pressure rod when rotating. The cleaning rod cleans the inner wall of the extrusion frame when rotating to prevent the melted medical polymer material from adhering to the inner wall of the extrusion frame. At the same time, the cleaning rod utilizes the elasticity of the elastic pressure rod to extrude the inner wall of the extrusion frame. The cleaning rod stirs the medical polymer material when rotating, and the medical polymer material flows inside the extrusion frame through stirring, so that the medical polymer material can fully contact with the stirring frame, so that the gas in the medical polymer material can be quickly discharged.
[0031] After being squeezed out, the gas in the medical polymer material of the present invention will enter the interior of the limiting frame. When the stirring frame rotates, it will contact the inclined plate and push the cylindrical rod to move upward. When the cylindrical rod moves upward, it pushes the sealing plate to move upward through the rectangular frame. At this time, the gas in the limiting frame will enter the interior of the exhaust frame through the air inlet hole. The sealing plate moves upward to squeeze the gas, so that the gas can be discharged through the one-way valve, thereby preventing the gas from accumulating inside the extrusion frame and repeatedly contacting the medical polymer material.
[0032] The twisting screw hole frame of the present invention rotates at the bottom of the unloading frame, and the screw hole frame drives the threaded ring to move upward when rotating. When moving, the threaded ring pushes the elastic rod to move upward through the connection between the connecting rod and the stabilizing plate, and the elastic rod pushes the stamping plate into the interior of the extrusion frame. At this time, the medical polymer material in the extrusion frame will enter the interior of the unloading frame, and the cleaning rod will contact the inclined contact frame when rotating and push the stamping plate to move downward. When the stamping plate moves downward, it will push the medical polymer material in the unloading frame into the interior of the molding device, so as to avoid the medical polymer material from accumulating in the interior of the unloading frame, and at the same time, the melted medical polymer material can quickly enter the interior of the molding device through the unloading frame for molding processing.
