Description
Technical field
The present invention relates to a kind of clamping, be particularly used for plastic-injection moulding machine, rubber injection moulding machine and
The balanced type of die casting machine belongs to clamping technical field without pull bar clamping.
Background technology
At present, mainly there are two kinds of structures of c-type and H types without pull bar clamping.C-type is to utilize c-type without pull bar clamping
Frame bears clamp force, the c-type stand stretch under clamp force effect, causes template not parallel, so that mold damage or influence system
The shaping of product, to reduce stand stretch, the rigid design of frame obtains very high, causes design cost very high；For Reducing distortion is made
Into harm, be designed with the flexible hinge by patent protection.But theoretically c-type can not be avoided that without drag link mechanism
The generation of stand stretch, the harm to mould and shaping is constantly present；H types leading using two high intensity without pull bar clamping
Post bears clamp force, is balance clamp force, generally sets lower section balancing cylinder, and this structure can considerably reduce template deformation
To mould and the harm of shaping, but due to needing to balance up and down, the rigidity of solid plate and tank plate need to be designed to very high, be directed at
This two pieces of templates are quite weighed, and design cost is also very high, and theoretically this structure also can not possibly completely avoid template deformation
Occur, so as to the harm to mould and shaping is constantly present.
Both the above type without pull bar clamping has the pull bar clamping cost to be higher by 50% than the common of same tonnage
More than, and their deformation can cause the not parallel of mould, have certain harm to mould and shaping, although so without pull bar
Machine has many good qualities, but the occupation rate of market with both injection machines without drag link mechanism is not high.
The content of the invention

Specific embodiment
The present invention will be further described with reference to the embodiment in accompanying drawing below：
As shown in figure 1, the invention mainly comprises moving platen 1, solid plate 2, the first mould 5, the second mould 10, bearing rod 13, embrace
Close mechanism 14 and machine locking mould driving mechanism 15.
Moving platen 1 and solid plate 2 or so be arranged in parallel, and the one end of bearing rod 13 connection solid plate 2, the other end passes through moving platen
1 and obvolvent mechanism 14 is connected, to be slidably matched between moving platen 1 and bearing rod 13.Machine locking mould driving mechanism is connected on moving platen 1
15, machine locking mould driving mechanism 15 can provide the driving force of moving platen 1 and the locking of solid plate 2.
The left and right two ends of moving platen 1 are respectively articulated with the first dynamic model bearing 3 and the second dynamic model bearing 8 by bearing pin, and first moves
The dynamic model bearing 8 of mould bearing 3 and second is separately fixed at the first dynamic model installing plate 4 and the back side center of the second dynamic model installing plate 9
Place.The upper and lower ends of solid plate 2 are respectively articulated with the first cover half bearing 7 and the second cover half bearing 12, the first cover half branch by bearing pin
The cover half bearing 12 of seat 7 and second is separately fixed at the back side center position of 6 and second cover half installing plate of the first solid plate dress plate 11.
The first mould 5, the upper and lower mould point of the first mould 5 are provided between first dynamic model installing plate 4 and the first solid plate dress plate 6
The front of the first dynamic model installing plate 4 and the first solid plate dress plate 6 front are not fixed on, and the front of the first dynamic model installing plate 4 and first is determined
Template dress plate 6 front is correspondingly arranged so that the upper and lower mould of the first mould 5 being capable of smooth matched moulds.
Be provided with the second mould 10 between second dynamic model installing plate 9 and the second cover half installing plate 11, the second mould 10 it is upper and lower
Mould is separately fixed at the front of the second dynamic model installing plate 9 and the front of the second cover half installing plate 11, the front of the second dynamic model installing plate 9 and
The front of two cover half installing plate 11 is correspondingly arranged so that the upper and lower mould of the second mould 10 being capable of smooth matched moulds.
Locking nut 16 is connected on the bearing rod 13, solid plate 2 is locked at the one end of bearing rod 13 by locking nut 16.
The obvolvent mechanism 14 includes cohesion nut of the amplexis on bearing rod 13, and executing agency is connected on cohesion nut,
Cohesion nut is driven by executing agency, so as to open or obvolvent.
The machine locking mould driving mechanism 15 is using driver parts such as oil cylinder, cylinders.
Operation principle of the invention is：During matched moulds, moving platen is moved by shifting formwork drive device band trend solid plate, and mould is closed
After upper, obvolvent mechanism is by its executing agency's obvolvent on bearing rod.Machine locking mould driving mechanism is pressurized, and produces clamp force, on the one hand
Bearing rod is elongated, and another aspect active and inactive mold plate can occur bending and deformation, due between active and inactive mold plate and active and inactive mold tool installing plate
Connected with hinge, this connection only can transmit push-pull effort, moment of flexure will not be transmitted, along with hinging pin shaft is connected to active and inactive mold
Has the centre of installing plate, mould action power on a mounting board will not cause the deformation of installing plate, so mold mounting plate can not
Can deform, cover half installing plate and dynamic model installing plate keep strict parallel, will not on any influence of parallel generation of mould,
Product molding is not interfered with yet.As shown in Fig. 2 being the deformation that each part is produced after applying clamp force.
Of the invention is a kind of clamping of balanced type without pull bar clamping, forms two without pull bar die region,
Produced simultaneously using two pairs of identical or close moulds of projected area size, can be with parallel, the save space of strict guarantee mould；
Simultaneously because using same hydraulic power supply, design cost is substantially reduced compared with two single equipment.
For not parallel, the conjunction of the design that solves the existing active and inactive mold plate caused without pull bar clamping template or stand stretch
By using two pairs of close moulds of projected area size, during mold-locked and injection, two secondary moulds are produced mold mechanism
In the case that the raw mould power that rises is more or less the same, cancel out each other, the deformation of machine components occurs in moving platen, solid plate and bearing rod
On, and the installing plate of installation mold will not occur any deformation in itself, thus completely eliminate existing without pull bar clamping
The shortcoming that frame or template can deform in locking and injection.
