There is one section of straightway 1c1, remaining is arc section 1c2 in annular guide channel 1c.Figure of description provides plastics embryo and squeezed
Go out the front side that machine also is located at blow moulding machine, then straightway 1c1 is located at the front side portion of blow moulding machine, and straightway 1c1 opens multiple blow molding dies
Attach together and put 3 linear motions, and then for ensureing that plastics embryo and the center line of blow molding die 4 overlap, improve product quality and qualification rate.
By illustrating that continuously making container using plastics embryo extruder and this blow moulding machine further illustrates the folding of this blow molding die
The principle of device 3 and blow moulding machine, and effect and the advantage of all parts：With container match blow molding die 4 left half module and the right side
Half module is separately fixed on two pieces of mold mounting plate 3b；In other words, a pair is respectively and fixedly provided with each group of blow molding die closing device 3 to blow
Mold 4.
Rotating disk 2 is connected with actuator；Actuator drives rotating disk 2 continuous and stable evenly along shown in Fig. 1 arrows
Direction rotates.Rotating disk 2 forces blow molding die closing device 3 to be moved along annular guide channel 1c, and radially-directed structure both enables blow molding die
Closing device 3 moves along arc section 1c2, also blow molding die closing device 3 can be made to be moved along straightway 1c1；Blow molding die folding
Device 3 moves from bottom to top in straightway 1c1.There is multigroup blow molding die closing device 3 simultaneously in straightway 1c1, positioned at straight
The adjacent spacing of blow molding die closing device 3 in line segment 1c1 is less than adjacent of blow molding die closing device 3 being located in arc section 1c2
Away from.
Blow molding die closing device 3 on straightway 1c1 is located at the top of extruder head 6a in plastics embryo extruder.In order to
It to be easy to describe, the blow molding die closing device 3 that definition is located at the top in straightway 1c1 is the first station blow molding die closing device 3,
Blow molding die 4 in the first station blow molding die closing device 3 is the first station blow molding die 4；It is most lower in straightway 1c1
The blow molding die closing device 3 of side is 3rd station blow molding die closing device 3, in 3rd station blow molding die closing device 3
Blow molding die 4 be 3rd station blow molding die 4；Filled positioned at the first station blow molding die closing device 3 and the folding of 3rd station blow molding die
It is second station blow molding die closing device 3 to put the blow molding die closing device 3 between 3, is filled installed in the folding of second station blow molding die
It is second station blow molding die 4 to put the blow molding die 4 in 3.
Each blow molding die closing device 3 can independent operation, the first station blow molding die 4 and second station blow molding die 4, which are in, to be closed
Mould state, during 3rd station blow molding die 4 is in from die sinking to matched moulds, thus plastics indusium is drawn straight up, Jin Erneng
Ensure that plastics embryo overlaps with the center line of 3rd station blow molding die 4, and then improve the quality and qualification rate of product.
Product can complete blow molding in the first station blow molding die closing device 3；Along the direction of rotation of rotating disk 2, from
One station to 3rd station, blow molding die 4 carries out cooling procedure successively, from matched moulds to die sinking process and from die sinking to matched moulds process.
Blow molding die 4 is set to be in die opening state positioned at the blow molding die closing device 3 of bottom, such product can be easier under gravity
The demoulding.
Because the adjacent spacing of blow molding die closing device 3 in straightway 1c1 is smaller, thus caused waste material also compared with
It is few.Due to two neighboring blow molding die closing device 3, from straightway 1c1 to arc section 1c2, spacing increases again, and then makes positioned at adjacent
Plastics indusium between blow molding die closing device 3 is pulled out and is broken, and is achieved in product stripping one by one.
During from 3rd station to second station, oil cylinder 3e buffering stem 3e5 is penetrated in cushion collar 3e3, piston rod
3e2 movement velocity is gradually reduced, until completing matched moulds；Which matched moulds can significantly improve product bottom uniformity, bottom envelope
Mouth sealing qualification rate and reduction noise.Gradual from matched moulds to the starting stage of die sinking process, oil cylinder 3e buffering stem 3e5
Cushion collar 3e3 is skidded off, piston rod 3e2 movement velocity gradually steps up, and then significantly decreases product and deformed during die sinking
Or tear probability.Remaining period uniform motion of oil cylinder 3e, is effectively ensured open mold efficiency.
