Bottle blowing machine with limiting assembly

Abstract

The invention relates to a bottle blowing machine with a limiting assembly. A mold opening and closing structure of an existing bottle blowing machine needs a large axial placement space, and use is affected. The bottle blowing machine comprises a rack, wherein the mold opening and closing structure is arranged on the rack and comprises two limiting working faces, and the limiting assembly and a mold assembly are arranged between the limiting working faces. When the mold assembly is axially closed to a mold closing station from a mold opening station, the limiting assembly moves to a clampingstation from an idle station, so that the limiting working faces axially clamp the mold assembly through the limiting assembly. The limiting assembly capable of avoiding opening and closing of the mold assembly is arranged between the limiting working faces, the limiting assembly can form a movable space through receding and can also axially clamp the mold assembly, the applicability is improved,mounting in a small placement space is facilitated, the assembly and maintenance difficulty is lowered, the maintenance cost is reduced, the raw material consumption is reduced, and the raw material cost and the transportation cost are reduced.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a bottle blowing machine. Background technique [0002] The existing bottle blowing machine includes a frame, a conveying mechanism arranged on the frame, a heating mechanism and a bottle blowing mechanism arranged in sequence along the conveying mechanism, and the bottle blowing mechanism includes a mold opening and closing structure and a blowing structure for blowing bottles. . During operation, the preform is driven by the conveying mechanism and processed by the heating mechanism and the blowing mechanism in sequence. The heating mechanism plays a role in heating and softening the preform, and the blowing structure blows the preform. The blown preform acts as a shaper to shape the preform into a preset contour. [0003] The existing mold opening and closing structure includes two parallel and separate positioning plates, a mold assembly arranged between the positioning pl...

AI Technical Summary

Problems solved by technology

[0004] The existing mold opening and closing structure has the following defects: the inner end of the limit rod is fixedly connected to the back surface of the template, and when the mold assembly is switched to the mold opening station, the outer end of the limit rod will axially cross the To position the plate and move outward, it is necessary to reserve a large axial movable distance for the opening and closing mold structure;

[0009] To sum up, the existing opening and closing mold structure itself has a large axial dimension and requires a large installation space, which will not only increase the cost of raw materials and transportation due to the increase in raw material consumption, but also increase the cost due to the complexity of the structure and the weight of the parts. Larger size increases the difficulty of assembly and maintenance, and has higher requirements for installation space, which limits the installation and use of the device in workshops with small spaces and affects the applicability of the equipment
