Description

Bottle blowing machine goods bottom mould emptier

Technical field

The utility model relates to a kind of bottle blowing machine goods bottom mould emptier, belongs to the plastics machinery technical field.

Background technology

With plastics such as PET is raw material, adopt and annotate stretch blow processing mineral water bottle, beverage bottles such as Coke bottle, be generally four paws (dividing four parts) or five pawls (dividing five parts) at the bottom of its bottle, existing bottle blowing machine is in order to enhance productivity, 2 or 3 of one mould processing, 4 plastic bottles, some reaches 6, promptly so-called one goes out two, one goes out three ... 2 of one mould processing, 3,4 plastic bottles, add to make with regard to inconvenience man-hour and from mould, take out bottle by hand, only reliable automatic demoulding, described automatic demoulding is installed ejecting mechanism above the bottle blowing machine mould, when plastic bottle stretch blow moulding, then after the mould die sinking, ejecting mechanism promotes plastics spout, makes plastic bottle pour out the disengaging mould to pushing direction, this for the four stars plastic bottle at the bottom of easy release come off automatically, if the bed die card of (five pawls) and mould gets firmly at the bottom of the five-pointed star bottle, the plastic bottle after the release still can hang on the bed die and can not come off fully.Therefore, the plastic bottle at the bottom of the prior art processing five-pointed star bottle has only by craft gets bottle, has influenced production efficiency.

Summary of the invention

The purpose of this utility model is the shortcoming at prior art; the button bottle fastened bottleneck when a kind of dynamic model die sinking was provided; bed die moves up simultaneously; make realization automatic demoulding at first disconnected from each other at the bottom of bed die and the plastic bottle; change manual mode of operation, thus the bottle blowing machine goods of enhancing productivity bottom mould emptier.

The technical scheme that the utility model adopted is to achieve the above object of the invention:

Bottle blowing machine goods bottom mould emptier; comprise die frame; left moving platen is installed on the die frame; right moving platen and end template; on the moving platen of a left side left dynamic model is installed; on the right moving platen right dynamic model is installed; bed die is installed on the end template; a described left side; right dynamic model top is limiting plate fixedly; limiting plate matches with the sidewall of end template or bed die; it is characterized in that a left side; the die orifice position installing tache bottle of right dynamic model; described button bottle is included on left dynamic model and the right dynamic model and respectively is shaped on chamber, and compression spring and bayonet socket push pedal are set respectively in each chamber, and the compression both ends of the spring contacts mutually with moving platen and bayonet socket push pedal respectively; in the described bayonet socket push pedal bayonet socket is installed; bayonet socket matches with the bottleneck of plastic bottle, and bayonet socket exposes a left side during die opening state; right dynamic model, the bayonet socket exposed length is greater than the spacing length of described limiting plate.

Characteristics of the present utility model are the left sides at existing bottle blowing machine, the button bottle has been installed at the die orifice position of right dynamic model, described button bottle is included in a left side, be shaped on chamber on the right dynamic model, compression spring and bayonet socket push pedal are set in the chamber, the compression both ends of the spring contacts mutually with moving platen and bayonet socket push pedal respectively, in the described bayonet socket push pedal bayonet socket is installed, bayonet socket matches with the bottleneck of plastic bottle, and bayonet socket exposes a left side when die opening state, right dynamic model, the bayonet socket exposed length is greater than the spacing length of described limiting plate, therefore in the die sinking process, a left side, right moving platen begins to move when having moved the spacing length of limiting plate, bayonet socket remains the plastics spout that links closely owing to be compressed the restoring force effect of spring, and this moment, bed die began to move up and goods bottoms is separated, automatic demoulding when having realized die sinking, last bayonet socket just breaks away from plastics spout, has finished whole knockout course.Realize the full-automatic demoulding by bottle blowing machine like this, need not manually to get bottle, improved production efficiency, and reduced accident rate.This mould emptier does not need to put power in addition, and is simple in structure, reliable operation.

In the described compression spring guide post is arranged, guide post is installed in the bayonet socket push pedal; There has been guide post to avoid compressing spring bending, flexible more stable.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

As Fig. 1-shown in Figure 4; bottle blowing machine goods bottom mould emptier; comprise die frame 9; left moving platen 13 is installed on the die frame 9; right moving platen 11 and end template 8; on the moving platen 13 of a left side left dynamic model 14 is installed; on the right moving platen 11 right dynamic model 12 is installed; bed die 10 is installed on the end template 8; a described left side; right dynamic model 14; 12 tops are limiting plate 7 fixedly; limiting plate 7 matches with the sidewall of end template 8 or bed die 10; it is characterized in that a left side; right dynamic model 14; 12 die orifice position installing tache bottle; described button bottle is included in a left side; right dynamic model 14; be shaped on chamber on 12; compression spring 4 and bayonet socket push pedal 2 are set in the chamber; compression spring 4 two ends contact mutually with moving platen and bayonet socket push pedal 2 respectively, and bayonet socket 1 is installed in the described bayonet socket push pedal 2, and bayonet socket 1 matches with the bottleneck of plastic bottle 15; bayonet socket 1 exposes a left side during die opening state; right dynamic model 14; 12, reveal bayonet socket 1 and go out the spacing length L of length H greater than described limiting plate 7.Characteristics of the present utility model are the left sides at existing bottle blowing machine, right moving platen 14, the button bottle has been installed at 12 die orifice position, described button bottle is included in a left side, right dynamic model 14, be shaped on chamber on 12, compression spring 4 and bayonet socket push pedal 2 are set in the chamber, compression spring 4 two ends contact mutually with moving platen and bayonet socket push pedal 2 respectively, bayonet socket 1 is installed in the described bayonet socket push pedal 2, bayonet socket 1 matches with the bottleneck of plastic bottle 15, and bayonet socket 1 exposes a left side when die opening state, right
