Description

Vertical cooling vacuum die bottom mechanism for bottle making machine

Technical Field

A vertical cooling vacuum mold bottom mechanism for a bottle making machine belongs to the field of glass production equipment.

Background

When producing glass bottles on a bottle making machine, the primary blank is finally transferred into a forming die on the forming side, and the final forming is completed in the forming die. As is known from the common knowledge in the art, the production efficiency of a glass bottle is greatly related to the cooling of a forming die, wherein the vertical cooling process (hereinafter referred to as "vertical cooling process") is a very effective improvement method to the forming die, and the roundness (outer circle of cross section) of the glass bottle can be improved by a vacuum assisted forming process. The blowing process of the forming die is mainly completed at the upper part of the die bottom mechanism, and the bottom of the forming die is in butt joint with the die bottom mechanism through the die bottom. The support of the mold bottom mechanism in the prior art on the forming mold vertical cooling process and the support of the vacuum auxiliary forming process are insufficient, and the mold bottom mechanism is specifically expressed as follows: for the vertical cooling process, some users actively discard the vertical cooling channel provided in the mold bottom mechanism. The reason for this is that, depending on the process requirements, the vertical cooling channel is required to be closed after the forming die is opened. In a normal bottle making process, the switching frequency of the vertical cooling channel is high, so that the damper is difficult to bear high-frequency and high-strength impact of the damper plate, and the mechanism is damaged.

In order to solve the problem that the damper is damaged by impact, part of the technical proposal forms a gap between the damper plate and the damper after the damper plate is completely closed, and in the proposal, the vertical cooling channel cannot be tightly closed although the problem that the damper is damaged by impact is avoided. The consequence is that after the forming die is opened, the die bottom on the surface of the die bottom mechanism is easily blown up by the vertical cold air flow, so that the whole bottle making process is interrupted, and the whole process is greatly influenced.

For a vacuum assisted molding process: the traditional die bottom mechanism is provided with a turnover device, so that vacuum channel leakage is easy to cause, and a user cannot realize a vacuum auxiliary forming process. Although the overturning device is omitted in the partial mold bottom mechanism, the tight closing of the forming mold is affected when the vacuum auxiliary forming process is implemented, and other serious defects are caused in the formed bottle.

Therefore, the design of the mold bottom mechanism which can help to complete the vertical cooling process and the vacuum auxiliary process in the forming mold simultaneously so as to improve the bottle making efficiency and the qualification rate is a technical problem to be solved in the field.
