Problems solved by technology

[0003] The disadvantage of the above prior art is that: when the guide roller is running at high speed, the guide roller will continuously hit the cam guide rail, and when the speed reaches a certain speed, the component force borne by the cam surface will exceed the bearing range of the roller mounting part. The speed cannot be further increased, and at the same time, it will cause serious wear of the guide rollers and cam guide rails, which will affect the opening and closing accuracy of the left mold and the right mold, and affect the mechanical stability of the blow molding machine when it is running at high speed

Abstract

The invention relates to the field of bottle blowing machines, in particular to a servo motor mold opening and closing mechanism for a rotary bottle blowing machine. A hanging-lug-type mold carrier is adopted. The servo motor mold opening and closing mechanism comprises a connecting assembly connected to the hanging-lug-type mold carrier, and the connecting assembly is connected with a servo motor through a lead-screw and bushing transmitting mechanism. According to the servo motor mold opening and closing mechanism for the rotary bottle blowing machine, as the hanging-lug-type mold carrier, the connecting assembly, the lead-screw and bushing transmitting mechanism and the servo motor are arranged, track-free mold opening and closing control is achieved, and the multiple defects of a rotating speed bottleneck, serious abrasion, poor mold assembling-disassembling precision and poor mechanical stability of a track mold opening and closing mechanism in the prior art are overcome.

Description

technical field [0001] The invention relates to the field of blow molding machines, in particular to a servo motor mold opening and closing mechanism for a rotary blow molding machine. Background technique [0002] In the prior art, the mold opening and closing mechanism used in the rotary blow molding machine is a track opening and closing mold mechanism, which is driven by the motor through the drive turntable to drive the outer tooth turntable to rotate, and synchronously drives the I-shaped rotary seat and the mounting bracket to rotate. Make the guide roller a12 of the guide rod a11 move along the curved surface of the cam guide a1, during the process of the guide roller a12 moving along the cam guide a1, the guide roller a12 drives the guide rod a11 to swing around the second movable axis a10, synchronously drives the second connecting rod a9 swings, the second connecting rod a9 drives the two first connecting rods a7 to swing through the first pin shaft a8, and then d...
