Problems solved by technology
[0003] The bottom mold in the existing bottle blowing mold base is supported on the upper limit by a spring. When the bottle is formed, the bearing on the bottom mold slides to the supporting guide rail, and the bottom mold is pulled down by the guide rail so that the bottle can be taken out. During the operation of the machine, the bearings on the bottom mold of this linkage mechanism will frequently hit the surface of the guide rail, which will generate a lot of noise and easily cause damage to the bearings. The service life is short and the maintenance frequency is high. for further improvement

The invention relates to a bottle blowing mold frame linkage mechanism. The bottle blowing mold frame linkage mechanism comprises a support, a clamping block, a middle shaft, a right mold shell, a left mold shell, a supporting base, a linear guide rail, a sliding block, a sliding base, a first bearing, a first rotary shaft, a third rotary shaft, a second bearing, a rotary supporting base, a first segregating bushing, a second segregating bushing, a third segregating bushing, a traction block, a traction assembly and an oscillating bar. According to the bottle blowing mold frame linkage mechanism, bearings are arranged inside the traction block; the bearings can roll back and forth along sliding grooves inside the traction block; and on this account, up-down movement of a bottom mold is achieved, noise is weakened substantially, and the bearings are prevented from striking the surface of the guide rail frequently; the service life is prolonged; the repair frequency is lowered; and in addition, under driving of the bottle blowing mold frame linkage mechanism, the bottom mold moves rapidly and is in good cooperation with the left mold shell and the right mold shell.
Description
technical field [0001] The invention relates to a bottle blowing mold frame linkage mechanism. Background technique [0002] The blow molding machine is a kind of equipment that makes plastic particles into hollow containers through the blow molding process. In the rotary blow molding machine, the molding and taking out of the preform require the bottom mold to move upward or downward, and the bottom mold is set in the blow molding machine. The up and down movement is realized on the bottle mold frame by means of the sliding connection of the slider and the guide rail. [0003] The bottom mold in the existing bottle blowing mold base is supported on the upper limit by a spring. When the bottle is formed, the bearing on the bottom mold slides to the supporting guide rail, and the bottom mold is pulled down by the guide rail so that the bottle can be taken out. During the operation of the machine, the bearings on the bottom mold of this linkage mechanism will frequently hit t...
