The direct-pressing type mold opening and closing mechanism can eliminate oil stain pollution to improve sanitary conditions.
Description
Technical field
The utility model relates to injection machine field, especially a kind of direct press type injection moulding machine.
Background technology
In recent years, the medical plastic goods are widely used in medical field.The lasting soaring of medical expense forces people to take more efficiently measure to reduce costs, thereby makes the disposable medical plastic products replace sterilizable glassware.Medical plastic goods market increases rapidly with double-digit ratio every year, and this has brought opportunity for undoubtedly medical article enterprise.Very good as producing plastic products injection machine market.But medical industry has very strict health regulation and industry standard, and is particularly stricter to the requirement of dust, greasy dirt.
In original injection machine, collapsible form leads by four pull bars, and lubricating between fairlead and pull bar is very serious to the pollution of mould closing section.
Summary of the invention
In order to overcome the deficiency that oil pollution is serious, sanitary condition is relatively poor of existing direct press type injection moulding machine, the utility model provides a kind of direct press type clasp mould mechanism of eliminating the injection machine of oil pollution, improve sanitary condition.
The technical scheme that its technical problem that solves the utility model adopts is:
a kind of direct press type clasp mould mechanism of injection machine, comprise the matched moulds tailgate, Mode-locking oil cylinder, mould shifting oil cylinder, matched moulds two plates and close die plate, described matched moulds tailgate and close die plate and be fixedly mounted on frame, described Mode-locking oil cylinder is connected with described matched moulds tailgate, described Mode-locking oil cylinder and described matched moulds two plates over against, described mould shifting oil cylinder is arranged on described matched moulds tailgate, the expansion link of described mould shifting oil cylinder is connected with described matched moulds two plates, described matched moulds two plates are provided with locating hole, pass the matched moulds pull bar in described locating hole, the two ends of described matched moulds pull bar respectively with described matched moulds tailgate with close die plate and be fixedly connected with, the bottom of described matched moulds two plates is provided with the second linear slider, the second line slideway is installed on described frame, described the second linear slider is sleeved on described the second line slideway slidably.
Further, on described frame, prefill valve is installed, described prefill valve is connected with described matched moulds tailgate.
Described matched moulds tailgate and described Mode-locking oil cylinder are one.
Technical conceive of the present utility model is: without any related, pull bar has only played the connection function between front template and rear pattern plate in this structure, no longer do guiding use with pull bar for this clamping, collapsible form, and the processing request of pull bar has been reduced a lot; Because there is no movable friction between pull bar and template, so just do not need to lubricate, solved the pollution of greasy dirt to mould closing section from the source, the guiding of this mechanism is the line slideway guiding that is positioned on base by two groups, make the defective of guiding distortion because gravity causes the pull bar bending when having reduced the pull bar guiding, improved greatly kinematic accuracy.Adopt in addition vertical compression type mould-locking mechanism, do not have hinged and attrition surface, admittedly need not oil lubrication; Hydraulic cylinder adopts the combining structure sealing, the oil impregnate phenomenon can not occur.Above some design is thoroughly stopped greasy dirt and is produced.
The beneficial effects of the utility model are mainly manifested in: eliminate oil pollution, improve sanitary condition.
Description of drawings
Fig. 1 is the structure chart of the direct press type clasp mould mechanism of straight injection machine.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
with reference to Fig. 1, a kind of direct press type clasp mould mechanism of injection machine, comprise matched moulds tailgate 1, Mode-locking oil cylinder 2, mould shifting oil cylinder 3, matched moulds two plates 4 and close die plate 5, described matched moulds tailgate 1 and close die plate 5 and be fixedly mounted on frame, described Mode-locking oil cylinder 2 is connected with described matched moulds tailgate 1, described Mode-locking oil cylinder 2 and described matched moulds two plates 4 over against, described mould shifting oil cylinder 3 is arranged on described matched moulds tailgate 1, the expansion link of described mould shifting oil cylinder 3 is connected with described matched moulds two plates 4, described matched moulds two plates 4 are provided with locating hole, pass matched moulds pull bar 7 in described locating hole, the two ends of described matched moulds pull bar 7 respectively with described matched moulds tailgate with close die plate and be fixedly connected with, the bottom of described matched moulds two plates 4 is provided with the second linear slider, the second line slideway 8 is installed on described frame, described the second linear slider is sleeved on described the second line slideway 8 slidably.
In the present embodiment, adopt the liquid-filled speedup vertical compression of self-priming clamping.During matched moulds, at first pressure oil enter mould shifting oil cylinder 3 back cavities, promotes matched moulds two plates 4 and carry out rapid mould-moving.Because the plunger of Mode-locking oil cylinder 2 moves with matched moulds two plates 4, the interior formation negative pressure of Mode-locking oil cylinder 2 forces prefill valve 1 to be opened, and Mode-locking oil cylinder 2 is carried out automatic liquid feeding.When the template rapid mould-moving stopped, Mode-locking oil cylinder 2 passed into pressure oil, and prefill valve 10 cuts out, and realized the purpose of locked mode.The size of mold clamping force is decided by the sectional area of Mode-locking oil cylinder 2.During die sinking, pressure oil enters mould shifting oil cylinder 3 ante-chambers, pulls matched moulds two plates 4 to move backward, and prefill valve 1 is opened simultaneously, and Mode-locking oil cylinder 2 inner fluids are directly pushed back fuel tank, realizes quick die sinking action.
Mode-locking oil cylinder 2 and matched moulds tailgate 1 adopts integrated design, and Mode-locking oil cylinder 2 plungers are contained in matched moulds tailgate 1 inside, and so not only structure is compacter, and the intensity of matched moulds tailgate 1 is guaranteed.Matched moulds two plates 4 adopt unlubricated design, move forward and backward and do not use four traditional pull bars as four pull bar bearing tensions of guiding, but adopt line slideway, have not only realized the purpose of oil-free lubrication, and have made the matched moulds resistance less, and closing precision is higher.
