Description

Die block coordinated type bottle blowing machine module

Technical Field

The utility model relates to a rotary bottle blowing machine technical field, concretely relates to die block coordinated type bottle blowing machine module.

Background

The mold of the rotary bottle blowing machine in the prior industry generally comprises three parts, namely a movable mold fixed mold, a bottom mold and a mold lock, and the three parts are respectively controlled by three sets of corresponding guide rails.

With particular reference to figure 1 of the drawings,

the opening and closing mode of the fixed die part of the moving die is as follows: the die opening and closing bearing 2 does curvilinear motion on a track of the die opening and closing guide rail, the whole displacement of the whole die set is limited due to the fixation of the top of the suspension bracket 11, and the die opening and closing bearing 2 can only do arc reciprocating motion around the die opening and closing transmission shaft 3 when doing curvilinear motion in the die opening and closing guide rail, so that the opening and closing of the movable die 9 and the fixed die 10 are controlled through the die opening and closing transmission system 12.

Bottom die 6 up-down mode: the bottom die driving bearing 4 reciprocates up and down under the limitation of the bottom die guide rail, the spring 5 is compressed in the descending process of the bottom die driving bearing 4, the bottom die 6 is driven by the bottom die support 7 to withdraw downwards from the fixed die of the driven die, and when the bottom die driving bearing 4 is separated from the limitation of the bottom die guide rail, the spring 5 resets to push the bottom die driving bearing 4, the bottom die 6 and the bottom die support 7 to move upwards to send the bottom die 6 into the fixed die of the movable die.

The mode of the mold locking part is as follows: the mold lock opening and closing bearing 8 reciprocates up and down under the limitation of the mold lock guide rail, the principle is the same as that of the bottom mold 6, and when the movable mold 9 and the fixed mold 10 are clasped, the movable mold 9 and the fixed mold 10 are locked by the mold lock system; when the mold lock opening and closing bearing 8 is at the lowest position, the mold lock system is opened, and the movable mold 9 and the fixed mold 10 can be opened.

The three sets of corresponding guide rails respectively control the respective systems, so that high precision of matching of the three parts is required, and meanwhile, the cost of each guide rail is high. However, this is not the most important, and it is important to find that, in practical application, after the rotation speed of the single die set is increased to a certain value, the springs 5 of the bottom die portion are difficult to overcome the rotational inertia of the bottom die support 7, so that the bottom die driving bearing 4 cannot move along the curve of the bottom die guide rail under the action of the rotational inertia of the bottom die support 7, and a bouncing impact phenomenon between the bottom die driving bearing 4 and the bottom die guide rail is generated, which results in poor mechanical stability, thereby severely limiting the operation speed of the equipment and limiting the production efficiency. In addition, the jumping phenomenon can cause a large amount of noise generated by equipment, cause noise pollution, seriously affect the physical health of workers and greatly reduce the service life of the bottom die driving bearing 4.

If the jumping amplitude is large, the bottom die driving bearing 4 can be derailed and collide with a bottom die track system, so that huge economic loss and even casualty can be caused. If the technical difficulties can not be broken through, the development and innovation of the bottle blowing machine industry can be limited to a bottleneck.
