Sealed piece is located at rotation in sealing guide rail 15, and sealing guide rail 15 includes low level section and high-order section, at seaming roll 222
When low level section, mouth-sealed portion 221, which is in lower position, can block sealing boss, and formwork is made to be in mode-lock status, when sealing is rolled
When wheel 222 is in high-order section, mouth-sealed portion 221 is in higher position, is detached from sealing boss, keeps formwork in the unlocked state.
Back cover boss includes half back cover boss 23 being arranged on two and half formworks 2, and back cover part is located at below back cover boss,
And can be rotated with middle plate 12, back cover part includes back cover portion 231 and back cover idler wheel 232, and fixed part is equipped with back cover guide rail 16, works as mould
When shell and back cover portion 231 are rotated with rotating part, back cover idler wheel 232 is located at rotation in back cover guide rail 16, and back cover guide rail 16 includes
Low level section and high-order section, when back cover idler wheel 232 is in high-order section, back cover part can block back cover boss, when back cover part
When in low level section, back cover part is detached from back cover boss.
Bearing track 14, sealing guide rail 15 and back cover guide rail 16 belong to the fixed part of rack, 14 near-lying mode of bearing track
The high-order section of section, the low level section for sealing guide rail 15 and back cover guide rail 16 is corresponding, and formwork is in molding state at this time,
Clamping apparatus locks formwork；The low level of the remote mould section of bearing track 14, the high-order section for sealing guide rail 15 and back cover guide rail 16
Section is corresponding, and formwork is in die opening state, clamping apparatus unlock at this time.Therefore it is opened with the rotation of rotating part, formwork
Clamping apparatus unlock simultaneously, while formwork molds, clamping apparatus mode locking, mode locking no longer occupies extra time, so that entire week
Phase shortens, and working efficiency improves, and production capacity improves.The height variation of certain sealed piece and back cover part is not limited to the high-low-position of guide rail
Setting, such as can also be realized by devices such as cylinders.
As optional embodiment, the present embodiment further includes two clamp hand devices 33, is to send embryo clamp hand and take bottle respectively
Clamp hand；Clamp hand device 33 is connect with clamp hand gear 31, rack gear 11 simultaneously with two clamp hand gears, 31 engaged transmission；Work as formwork
In die opening state and rotation to when sending embryo position, send embryo clamp hand can will the bottle embryo of clamping be sent into formwork in；When formwork rotates
When to bottle outlet position and being in die opening state, takes bottle clip hand that can clamp bottle and leave formwork.
Specifically, as Figure 7-8, clamp hand device 33 includes swing part 334, pars contractilis 333, oscillating cam mechanism, stretches
Contracting cam mechanism and track plate 34, swing part 334 are connect with the oscillation bearing 332 of oscillating cam mechanism, pars contractilis 333 with stretch
The flexible bearing 331 of contracting cam mechanism connects.The outer side track of track plate 34 is that telescopic shaft holds tracks 341, track plate 34
Inner track be oscillation bearing tracks 342, when flexible bearing 331 and oscillation bearing 332 move to position as shown in Figure 8
When setting, flexible bearing 331 is able to drive pars contractilis 333 and compresses towards 334 direction of swing part, while swing part 334 is in swinging axle
Of short duration swing state is maintained under the action of holding 332, extends the docking time of clamp hand device 33 and formwork, and completion send embryo and takes bottle
Movement；The clamp hand device 33 of the present embodiment utilizes double-cam structure, and a cam mechanism realizes that clamp hand is swung, another cam machine
Structure realizes that clamp hand is flexible, it can be achieved that tracking of the clamp hand to die location, so that handover is more smooth.
In order to reduce failure, it is not drawn into the position setting pressure spring figure that pars contractilis 333 is connect with swing part 334.Pressure spring begins
It is in compressive state eventually, during pars contractilis 333 is compressed close to swing part 334, pressure spring is further compressed, and passes through pressure spring
The tension spring in traditional clamp hand device 33 is substituted, spring is can be avoided and is pulled off, is avoided because equipment fault is to production efficiency
It influences.
