Background technology
At present, the mold closing mechanism of machinery such as injection machine, die casting machine, most of toggle formula mold closing mechanism that adopts.Toggle formula mold closing mechanism uses three templates and many to the bearing pin toggle, exist axle sleeve to cooperate that more, lubricated node is more, complete machine is heavier, maintenance cost is higher and the large-tonnage mode transfer than shortcomings such as difficulties.
Also there is the small part mold closing mechanism to adopt the two-plate mold closing mechanism.The two-plate mold closing mechanism is that the high pressure die cylinder is designed into four jiaos of template (comprising solid plate and moving platen), and four jiaos of high pressure matched moulds rear pattern plate will can produce flexural deformations inevitably.And for the higher product of precision, must meet stress evenly, the little requirement of distortion, therefore in order to guarantee rigidity, must increase the template thickness of two-plate mold closing mechanism.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art part, provides a kind of center simple in structure to press the two-plate mold closing mechanism, and its moving platen that can eliminate mold closing mechanism is subjected to external force and the moment of flexure that produces, and can significantly reduce the thickness of moving platen.
For achieving the above object, the utility model adopts following technical scheme:
A kind of center is pressed the two-plate mold closing mechanism, comprises moving platen, solid plate and moving platen driving mechanism, and moving platen is provided with and ejects cylinder apparatus; Described moving platen is by forming with the back moving platen and the preceding moving platen of the coaxial setting of solid plate, and the central part of described back moving platen is provided with die cylinder, and the piston rod of this die cylinder is connected with the central part of preceding moving platen; The described cylinder apparatus that ejects is located in the preceding moving platen.
Further, described moving platen driving mechanism comprises the mould shifting oil cylinder device, and its cylinder body portion is fixed on the solid plate, and its piston rod is connected with the back moving platen; Guide pillar, the leading section of guide pillar is fixed on the solid plate by fixation kit, and the cylinder of guide pillar partly is arranged in preceding moving platen and the back moving platen; Be provided with locking mechanism between the rearward end of guide pillar and the back moving platen.
Further, described locking mechanism is the cohesion nut device, and the guide pillar rearward end has zigzag outer shroud tooth, encircles tooth in the zigzag that the cohesion nut device is provided with this zigzag outer shroud tooth matches.
Further, described fixation kit comprises guide pillar nut and guide pillar nut pressing plate, and the guide pillar nut is combined on the leading section of guide pillar, and guide pillar nut pressing plate is fixed as one guide pillar nut, guide pillar and solid plate by screw.
The utility model makes a moving platen compression chord by adopting said structure, eliminated fundamentally that moving platen is subjected to external force and the moment of flexure that produces, and then can significantly reduce the thickness of moving platen, and the stress of product is even, is out of shape little.

The specific embodiment
As shown in Figure 1, a kind of center described in the utility model is pressed the two-plate mold closing mechanism, mainly is made up of solid plate 1, moving platen, mould shifting oil cylinder device 4 and moving platen driving mechanism.
Moving platen is by forming with the preceding moving platen 21 and the back moving platen 22 of solid plate 1 coaxial setting, and the central part of back moving platen 22 is provided with die cylinder 3, and the piston rod of die cylinder 3 is connected with the central part of preceding moving platen 21; Before be provided with in the moving platen 21 and eject cylinder apparatus 8, and with the solid plate opposing end faces on dynamic model 92 is housed.
The moving platen driving mechanism mainly is made up of mould shifting oil cylinder device 4 and guide pillar 5.The cylinder body portion of mould shifting oil cylinder device 4 is fixed on the solid plate 1, and its piston rod then is connected with back moving platen 22.The leading section of guide pillar 5 and guide pillar nut 61 threaded engagement, and be fixed on the solid plate 1 by the leading section of screw with guide pillar nut 61, guide pillar 5 with guide pillar nut pressing plate 62.In moving platen 21 and the back moving platen 22, moving platen 21 and back moving platen 22 can move around along guide pillar before making before the cylinder of guide pillar 5 partly was arranged in.The rearward end of guide pillar 5 is provided with cohesion nut device 7, and the rearward end that reaches guide pillar 5 has the outer tooth ring 51 of zigzag, and cohesion nut device 7 then is provided with tooth ring in the zigzag that cooperates with the outer tooth ring 51 of this zigzag.
The course of work of the present utility model is as follows:
During matched moulds, moving platen 21 was carried out mould assembling action together before mould shifting oil cylinder device 4 drove 22 drives of back moving platen, encircle tooth pitch sum in distance less than in the thickness (the thickness sum of fixed half and moving half) of mould and the cohesion nut, greater than somewhere in the scope of the thickness of mould, 7 actions of cohesion nut device are meshed and locking guide pillar 5 the outer tooth ring of guide pillar 5 and the interior tooth ring of cohesion nut device 7, thereby prevent to move after back moving platen 21 further.Then, the rodless cavity of the die cylinder 3 on the back moving platen 22 plays pressure, and moving platen 21 drives dynamic models 92 reaches and cover half 91 first low pressure matched moulds before driving, high pressure matched moulds again, pressurize.Carry out injection (die casting machine) or injection (injection machine) action.After pressurize, the cooling, the rod chamber of the die cylinder 3 on the back moving platen 22 plays high pressure, carries out high pressure die sinking action, move a bit of distance behind the preceding moving platen after, cohesion nut device 7 is opened, releasing is to the locking of guide pillar.Moving platen 21 was carried out the die sinking action together before mould shifting oil cylinder device 4 drove 22 drives of back moving platen then.After die sinking put in place, the cylinder apparatus 8 of ejecting on the preceding moving platen 21 ejected goods from mould.The thimble of waiting to eject cylinder apparatus 8 can be carried out next cycle period after retreating and putting in place.
