Abstract

The utility model relates to a built-in type booster for an injection moulding machine mould locking device. The utility model is composed of a draw rod and a built-in boosting piston of the draw rod, wherein, the inner part of the head part of the draw rod is sheathed with a boosting piston seat; the inner part of the boosting piston rod is provided with a liquid channel from a boosting oil cylinder barrel to a boosting oil cavity, and the inner part of the liquid channel is provided with a one-way valve. The utility model has the advantages that a small oil return groove at the boosting oil cylinder barrel side is changed into the one-way liquid channel which is provided with a one-way valve in the middle of the boosting piston rod, by the high-speed oil return of the one-way valve and complete sealing transference pressure, the act is fast when a mould is locked, the oil is filled fast when the mould is opened, the response speed is increased, and the work efficiency is enhanced.

Description

The built-in supercharging device that is used for the injection moulding machine mode-locking device
Technical field
The utility model relates to a kind of built-in supercharging device, particularly relates to a kind of built-in supercharging device that is used for the injection moulding machine mode-locking device.
Background technology
The built-in supercharging device of existing hydraulic locking system is made up of following parts as shown in Figure 1:
One head is the pull bar 3 of piston-like, and piston head 31 downsides of pull bar have side path 32, and from first to last there is passage 33 inside and is communicated with side path 32, and the internal diameter at side path place is greater than its inboard internal diameter;
One pressurizing cylinder connects piston rod 7 by charged piston 8 and inserts in the pressurised oil cylinder barrel 4, and piston cylinder head 41 constitutes supercharging oil pocket 6 greater than the inboard inner chamber of pull bar with pull bar, and the head downside has logical liquid sulculus 42;
Logical piston seat 2 in one places the inner passage of pull bar 3 heads, and the piston cylinder head that limits pressurizing cylinder shifts out the pull bar internal channel.
When above-mentioned built-in supercharging device is used for the injection moulding machine mode-locking device, pull bar is passed moving die plate 5, head piston 31 is inserted in the Mode-locking oil cylinder tube 1.
As shown in Figure 1, during die sinking, locked mode oil pocket 11 left side constant voltages promote pressurizing cylinder piston rod 7 and move to right, and this moment, hydraulic oil passed through sulculus 42, and repairing is that next high-voltage lock mould stores oil mass to supercharging oil pocket 6.Sulculus 42 openings are big more, and oil return is fast more, and the oil return process just can shorten, so sulculus 42 openings are the bigger the better.
As shown in Figure 2, Guan Moshi, P holds oil-feed, and oil pressure promotes pressurizing cylinder and moves to left, and realizes high-voltage lock mould.Make supercharging oil pocket 6 with Mode-locking oil cylinder 11 communicate because sulculus 42 can leak oil this moment, the pressurised oil that slows down cylinder barrel 4 speed that moves to left, and if sulculus 42 openings excessive, high-voltage lock mould might occur and lock not on, so sulculus 42 openings are the smaller the better at this moment.
In sum, be the bigger the better during the sulculus die sinking of present this supercharging clamping apparatus structure, the smaller the better when closing mould, so the shortcoming that exists its groove size to be difficult to determine.
Summary of the invention
Technical problem to be solved in the utility model is to overcome present above-mentioned shortcoming and a kind of built-in supercharging device that is used for the injection moulding machine mode-locking device is provided, and realizes the quick oil return and the purpose of locked mode fast.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Utilize the existing built-in supercharging device that is used for the injection moulding machine mode-locking device, change the original supercharging oil pocket that passes through the sulculus on the piston barrel to the fluid passage of locked mode oil pocket into interior fluid passage by the band check valve in the middle of the charged piston bar, quick in the time of can realizing supercharging oil pocket feed liquor like this, can pressure release when transmitting pressure.
Described check valve is located at piston rod head, and is easy for installation like this.
Described fluid passage has several uniform vertically side paths at underpart of the piston rod, and piston rod is stressed evenly like this.
Compared with prior art, advantage of the present utility model is the oil return sulculus of pressurised oil cylinder barrel side is changed into the unidirectional fluid passage of the middle band check valve of charged piston bar, quick oil return and hermetically sealed pressure transmission by check valve, make quick acting when closing mould, rapid refueling during die sinking, increase response speed, increase work efficiency.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 3, built-in supercharging device is made up of following parts:
One head is the pull bar 3 of piston-like, and piston head 31 downsides of pull bar have side path 32, and from first to last there is passage 33 inside and is communicated with side path, and the internal diameter at side path place is greater than its inboard internal diameter;
One pressurizing cylinder, connecting piston rod 7 by charged piston 8 inserts in the pressurised oil cylinder barrel 4, piston cylinder head 41 has the fluid passage 71 from the pressurised oil cylinder barrel to the supercharging oil pocket greater than the inner chamber of pull bar inboard in the described charged piston bar, and establishes check valve 9 at fluid passage 71;
Logical piston seat 2 in one places the inner passage of rod head, and the piston cylinder head that limits pressurizing cylinder shifts out the pull bar internal channel.
When above-mentioned built-in supercharging device is used for the injection moulding machine mode-locking device, pull bar is passed moving die plate 5, head piston 31 is inserted in the Mode-locking oil cylinder tube 1.
As shown in Figure 3, during die sinking, locked mode oil pocket left side constant voltage promotes pressurizing cylinder piston rod 7 and moves to right, check valve 9 unlatchings this moment, and hydraulic oil is by check valve 9, and repairing is to supercharging oil pocket 6, for next high-voltage lock mould stores oil mass fast.
As shown in Figure 4, Guan Moshi, P holds oil-feed, oil pressure promotes pressurizing cylinder and moves to left, and this moment, supercharging oil pocket 6 separated with Mode-locking oil cylinder 11 because check valve 9 is closed, pressure in the supercharging oil pocket 6 all is delivered to the pressurised oil cylinder barrel, and the speed that moves to left is very fast, thereby realizes quick, reliable locked mode.
