The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As shown in Figure 1 and Figure 2, plastic bottle closing device of the present utility model, two that comprise bearing 1, are installed on the bearing 1 and can move on bearing 1 are sealed half module 21 and are used for driving two matched moulds assemblies that seal half module 21 foldings.The matched moulds assembly comprises driving cylinder 3 and link gear, two are sealed half module 21 and link to each other by link gear, one of them seals half module 21 and is connected with the expansion link 31 of driving cylinder 3, is driven by driving cylinder 3 and moves, and drive another by link gear and seal half module 21 reversing senses and move.So, two seal half module 21 can by link gear mutually near or mutually away from, thereby realize matched moulds and die sinking.Driving cylinder 3 in the present embodiment is servo cylinder or servo electric jar or servo hydraulic cylinder.In the present embodiment, two are sealed half module 21 by the same moved further of link gear, are easy to guarantee the accuracy of matched moulds and die sinking.

In the present embodiment, link gear comprises one group of above fork group, the fork 5 and first fork 6 in the middle of every group of fork group comprises.In each fork group, the middle part of middle fork 5 is articulated on the bearing 1, one end of middle fork 5 and an end of first fork 6 are hinged, the other end of middle fork 5 seals half module 21(present embodiment for sealing half module 21 by driving cylinder 3 drivings with one of them) link to each other, the other end of first fork 6 is articulated in another and seals on the half module 21.Mutual action by the middle fork 5 and first fork 6 is realized two interlocks of sealing half module 21.Certainly, in other embodiments, for realize two seal half module 21 synchronously mutually near or synchronously mutually away from, link gear also can be other forms of many rod member combinations.

In the present embodiment, the other end of middle fork 5 links to each other with the half module 21 that seals that is driven by driving cylinder 3 by second fork 7, wherein, an end and the middle fork 5 of second fork 7 are hinged, and the other end of second fork 7 is articulated in by sealing on the half module 21 that driving cylinder 3 drives.Because the path of motion of fork 5 ends is camber line in the middle of when middle fork 5 is swung, and the path of motion of sealing half module 21 is straight line, by hinged second fork 7 of between, just the straight line that seals half module 21 can be moved the circular swing motion of fork 5 in the middle of successfully being converted into.

In the present embodiment, the fork group is two groups, and is symmetrically arranged in the two ends of sealing half module 21.

In the present embodiment, two are sealed half module 21 and are installed on the bearing 1 by guideway 4, to realize that sealing the straight line of half module 21 on bearing 1 moves.The arranged direction of guideway 4 is identical with the flexible direction of driving cylinder 3.

Principle of work of the present utility model: as shown in Figure 1, two are sealed half module 21 when opening, and the expansion link 31 of driving cylinder 3 is in contraction state; During matched moulds, the expansion link 31 of driving cylinder 3 stretches out, promotion is attached thereto seal that half module 21 moves and seal half module 21 to another close, simultaneously, this seals the mutual action of half module 21 by second fork 7, middle fork 5 and first fork 6 and drives another and seal half module 21 same moved further, and close with it, to seal half module 21 close mutually synchronously thereby make two, realizes matched moulds (referring to Fig. 2); During die sinking, expansion link 31 withdrawals of driving cylinder 3, the half module 21 that seals that pulling is attached thereto moves and seals half module 21 away from another, simultaneously, this seals the mutual action of half module 21 by second fork 7, middle fork 5 and first fork 6 and drives another and seal half module 21 same moved further, and with it away from, thereby make two seal half module 21 synchronously mutually away from, realize die sinking (referring to Fig. 1).

Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
