Abstract
The utility model relates to a mould closing and locking device for stretching blow moulding machines, which is a component of equipment for producing hollow plastic vessels. The utility model comprises a group of mould plates of a stretching blow moulding machine, and the mould plates are connected in series by guide posts. The bottom of each mould plate is connected with a guide rail of a stretching blow moulding machine. A mould is arranged in the mould plates and a mould closing cylinder is connected in the mould plates. The rear wall of a middle mould plate is connected with a mould closing piston rod and a mould locking cylinder simultaneously. The mould closing cylinder is arranged on the outer wall of a rear mould plate. One end of the mould locking piston rod in the mould locking cylinder is connected with a piston, and the other end of the mould locking piston rod is provided with a bayonet. A mould locking chock cylinder is arranged on the inner side of the rear mould plate and a piston rod of the mould locking chock cylinder is connected with a mould locking chock which is provided with a mould locking groove inside. The mould locking groove is matched with the mould locking piston rod and the bayonet. The technical proposal, after the mould plates for connecting moulds are closed, is further locked by the mould locking mechanism to avoid mould expansion and ensure the quality of produced plastic products.
Description
Technical field
The utility model relates to the process equipment of plastic hollow vessel, is the stretch blowing machine that two-step method is produced plastic hollow vessel, particularly relates to the matched moulds clamping mechanism of stretch blowing machine, can be used for producing inflation or not pop bottle, bottle for cosmetics etc.
Background technology
Adopt and annotate stretch blow production plastic hollow vessel, as Coke bottle, mineral water bottle, bottle for cosmetics etc., its process equipment has one-step method and two-step method, and described two-step method is at first annotated raw material by injection machine and made bottle base, again by the bottle base stretch blow moulding of stretch blowing machine after with twice heating.Bottle base charges into Compressed Gas in the bottle in the stretch blow moulding, gas pressure is sent to mould through bottle, and such mould generally all is left and right matched moulds, so mould must have reliable clamping adding the expansive force that is subjected to air pressure man-hour.The matched moulds of prior art stretch blowing machine adopts one group of cylinder, does not have additional clamping apparatus, often occurs expanding mould and making product rejection.
Summary of the invention
The utility model provides the existing matched moulds of a kind of stretch blowing machine that the combined mechanism of locked mode is arranged again in order to overcome the defective of prior art.The technical scheme of its stretch blowing machine matched moulds clamping mechanism is: the template that one group of stretch blowing machine is arranged; each piece template is contacted by guide pillar; installation mold and connect the matched moulds cylinder in the template; the rear wall of template connects closing piston bar and locked mode cylinder simultaneously in it is characterized in that; the matched moulds cylinder is installed in the rear pattern plate outer wall; the locking piston bar one head of locked mode cylinder connects piston; and the other end is shaped on bayonet socket; locked mode chock cylinder is installed on the inboard of rear pattern plate; be shaped on the locked mode chute in the locked mode chock, the locked mode chute matches with locking piston bar and bayonet socket.And tooth bar is installed respectively on middle template and rear pattern plate, and pole is installed on guide rail, gear is arranged on the pole, form matched moulds locked mode lazy-tongs by gear and two tooth bars.This matched moulds clamping mechanism at first is that the matched moulds cylinder pushes away middle template forward (one with mould is preceding) through piston rod when work; simultaneously again through guide pillar with front template toward post-tensioning; make two mould matched moulds; the bayonet socket of locking piston bar arrives the runner position of locked mode chock at this moment; locked mode chock cylinder operation; make the locked mode chock insert bayonet socket; locked mode cylinder operation again; template and rear pattern plate in further promoting; strengthen front template and middle template making a concerted effort at last to mould; guarantee the stretch blow moulding, overcome the mould phenomenon that expands, improve product percent of pass.

Fig. 3 is shaped on the chute schematic diagram in the locked mode chock.
The specific embodiment
The utility model discloses a kind of matched moulds clamping mechanism of stretch blowing machine; be by front template 4; middle template 5 and rear pattern plate 10 are formed one group of template of stretch blowing machines; each piece template is by guide pillar 3 polyphones; the bottom of template contacts with the guide rail 1 of stretch blow machine; guide rail is installed in the stretch blow machine frame; installation mold and connect the matched moulds cylinder in the template; the matched moulds cylinder 13 of the technical program is installed in the outer wall of rear pattern plate 10; two moulds 2 are installed in respectively on front template 4 and the middle template 5; the rear wall of template 5 during the piston rod 14 of matched moulds cylinder 13 connects; and middle template rear wall is also installed locked mode cylinder 6 simultaneously; the piston rod 11 one heads of locked mode cylinder 6 connect piston 15; and the other end is shaped on bayonet socket 12; locked mode chock cylinder 9 is installed on the inboard of rear pattern plate 10, and the piston rod 8 of locked mode chock cylinder connects locked mode chock 7, is shaped on locked mode chute 19 in the locked mode chock 7; as shown in Figure 3, locked mode chute 19 matches with locking piston bar 11 and bayonet socket 12.Because locking piston bar 11 penetrates locked mode chute 19 all the time; and pass through template 5 in piston rods 14 promotions with matched moulds cylinder 13; be moved to the left as shown in Figure 1; and spur front template 4 simultaneously to the right; before making; in template to mould 2 matched moulds after; the bayonet socket 12 of locking piston bar 11 just in time moves in the locked mode chute 19; by 9 actions of locked mode chock cylinder; promote through piston rod 8, lock dog chock 7 is downward, and bayonet socket 12 is inserted on the top of chute 19; then locked mode cylinder 6 actions; template 5 and rear pattern plate 10 are to both sides in further being promoted by the locking piston bar, and purpose makes front template 4 and middle template 5 further clamping molds 2, reach behind the matched moulds locked mode purpose again. Tooth bar 16,18 is installed respectively on middle template 5 and rear pattern plate 10, pole 20 is installed on guide rail 1, gear 17 is arranged on the pole 20, form matched moulds locked mode lazy-tongs by gear 17 and two tooth bars 16,18, action links up consistent, template 5 oppositely moves with rear pattern plate 10 in making, and front template 4 and middle template 5 locking moulds 2.
