Left protruding pin 29 is hooked under the action of spring 30, left protruding pin is welded in left push plate, therefore left push plate is also and then moved to the left, mould
Tool is opened from A-A die joint；Similarly, at the same time, Bottom clamp plate 1 is moved to the left under the driving of power, due to levorotation core
Plate 2 is that screw connects with Bottom clamp plate 1, and levorotation core plate 2 is also and then moved to the left, and long rack gear is fixed on levorotation core plate plate, because
This long rack gear is also and then synchronized and is moved to the left, and long rack and pinion 2 26 engages, therefore rotates clockwise with moving gear 2 26；Tooth
It takes turns 2 26 to engage with gear 1, gear 1 is engaged with the gear wheel part of duplicate gear 27, gear 3 28 and duplicate gear
Pinion portion engagement；Since the logarithm of external gear pump is odd number, thus the steering of gear 3 28 and gear 2 26 on the contrary,
I.e. gear 3 28 is to rotate counterclockwise, and short rack and pinion 3 28 engages, and will be pushed when gear 3 28 rotates counterclockwise short
Rack gear 19 is moved to the left, and short tooth item is fixed in right core plate, therefore right core plate, also and then to right translation, right swing hook is in spring
Right protruding pin is hooked under the action of 22, right protruding pin is welded in right push plate, so that right pusher plate be driven to be moved to the left together, mold is
It is opened from B-B die joint；
The synchronous parting of two die joints is realized by gear and rack teeth mechanism and two swing hook protruding pin mechanisms in this patent.It is setting
It when counting gear mechanism, needs reasonably to select the number of teeth of gear, just can control the movement speed of two core plates of left and right, in this mold
Middle gear 28 is identical as the number of teeth of gear 26, according to train transmission ratio formula, when the canine tooth tooth number of duplicate gear 27 is small tooth
At twice of tooth number, by calculating it can be concluded that the revolving speed of gear 3 28 is the half of the revolving speed of gear 2 26, and due to this
Two gears（Gear 3 28 and gear 2 26）The number of teeth is identical, so can obtain the mobile speed of long rack gear 20 is that short tooth item 19 is mobile
Twice of speed.The mobile displacement of levorotation core plate is 2 times of right core plate moving displacement when being opened, to successfully realize two
It is opened while die joint.
The die sinking distance length of A die joint and B die joint is required fixed numbers, this patent when in order to guarantee die sinking
Provided with controlled interval pull rod, the length of left controlled interval pull rod 6 is 1.2 times of right controlled interval pull rod length, left controlled interval pull rod 6 in this patent
Length determine the die sinking distance length of die joint B（The distance of i.e. left push plate and right core plate）, the length of right controlled interval pull rod 9
Determine the die sinking distance length of die joint B（The distance of i.e. right push plate and cavity plate）；There is eave tile on the right of left controlled interval pull rod 6, it is right
There is boss on the left side of controlled interval pull rod 9, and there is eave tile on the right, and boss is arranged at the top of right cavity plate, and working principle is as follows：For B parting
Face, the length of left controlled interval pull rod 6 determine the size of the die sinking distance of die joint A, when die sinking, work of the Bottom clamp plate 1 in power
Under, left controlled interval pull rod is moved to the left together with levorotation core plate and left push plate, and mold is opened from B die joint, when left spacing is drawn
When the eave tile part of bar 6 contacts and hooks with the projection section of right controlled interval pull rod, left push plate cannot follow levorotation core plate to continue
It moves to left, left swing hook is detached from left protruding pin at this time, i.e. B die joint die sinking terminates.Similarly, for A die joint, right controlled interval pull rod 9
Length determines the size of the die sinking distance of die joint A, and when die sinking, right controlled interval pull rod is moved to left with right core plate and right push plate,
Mold is opened from A die joint, and due to the effect of train, the movement speed of right core plate is the half of levorotation core plate, so A parting
The die sinking distance in face also constantly increases, when the eave tile part of right controlled interval pull rod 9 contacts and hooks with the projection section of right cavity plate
When, right push plate cannot follow right cavity plate to continue to move to left, and right swing hook is detached from right protruding pin at this time, i.e. A die joint die sinking terminates.
In order to realize that the plastic for completing injection molding smoothly demoulds after die sinking, this patent uses the structure of swing hook boss, tool
Body running principle is as follows, after the die sinking of A die joint terminates, since the right controlled interval pull rod in right push plate hooks right cavity plate, because
This right push plate remains stationary, and right core plate continues to move to left under the action of short tooth item, and simultaneously the gib head of right swing rod overcomes
Spring force is detached from away from corresponding right protruding pin, and right swing rod is forcibly separating with right protruding pin, therefore right core plate continues to be moved to the left
And right pusher plate remains stationary, so that plastic product demoulds away from right core plate, that is, completes the de- of A die joint plastic
Mould；Similarly, after the die sinking of B die joint terminates, the eave tile part of the left controlled interval pull rod in left push plate is convex with right controlled interval pull rod
Platform part, which contacts, simultaneously mutually hooks, therefore left pusher plate remains stationary, and levorotation core plate continues under the action of injector to moving to left
Dynamic, the gib head of left swing bar overcomes spring force to be detached from away from corresponding left protruding pin at the same time, and left swing bar divides by force with left protruding pin
From levorotation core plate continues to be moved to the left at this time and left pusher plate remains stationary, therefore plastic product demoulds out from levorotation core plate
It goes, that is, completes the demoulding of B die joint plastic；
Other explanations：In order to guarantee that left and right swing hook smoothly hooks corresponding protruding pin, has separately designed left swing in molding
Hook release link and right swing hook release link, so that swing hook is maintained at certain position when being detached from corresponding protruding pin, thus in molding
It can smoothly reset, that is, hook corresponding protruding pin.
As further improvement, controlled interval pull rod can be set to implementing process such as apart from adjustable controlled interval pull rod
Under：
Apart from adjustable controlled interval pull rod by bridge 1 ', nut support bar 2 ', spring collar 3 ', screw rod 4 ', eave tile nut 5 ',
Screw rod gland 6 ', screw 7 ' composition；There is eave tile in the lower end of eave tile nut；Working principle is：When need to adjust controlled interval pull rod away from
From when, rotate clockwise or counterclockwise the handwheel on the right of screw rod 4, eave tile nut will be corresponding to the right or to moving to left
It is dynamic；So as to adjust the length of controlled interval pull rod, wherein left controlled interval pull rod is as shown in fig. 7, right controlled interval pull rod is as shown in Figure 8；
In this patent, the number of teeth selection of the big pinion gear of duplicate gear is related with the opening speed of two die joints in train
System, can reasonably select the number of teeth as the case may be.In this patent, the number of teeth of the gear wheel of duplicate gear is the pinion gear number of teeth
Twice.
