Description
Technical field
The utility model relates to the injection machine field, is a kind of two-plate type mould clamping mechanism specifically.
Background technology
So-called two plate machines are compared with common clamping and have been lacked rear pattern plate; so be referred to as two plate machines; owing to there is not rear pattern plate, generally adopt locking cylinder and locking nut to cooperate to replace elbow-bar mechanism, then Mode-locking oil cylinder is set in order to mould is produced clamp force between locking nut and moving platen.The two-plate type mould clamping mechanism of prior art; generally comprise moving platen, front template, pull bar, Quick cylinder and mould; the piston end of described Quick cylinder is connected with moving platen; pull bar is provided with gear ring; two halves formula locking nut is placed on the gear ring of pull bar, and is provided with the locking cylinder in order to hold-down nut.During matched moulds, Quick cylinder drives moving platen and carries out mould assembling action, adopts afterwards locking cylinder that locking nut is pinned, and with Mode-locking oil cylinder moving platen is produced clamp force again.When injection moulding, the two-plate type mould clamping mechanism of prior art need to lean on Mode-locking oil cylinder to produce larger clamp force, yet adopts the oil cylinder locked mode not only to consume energy greatly, and it is also large to wear and tear, and the clamp force skewness, affects quality of item.
The utility model content
The technical problems to be solved in the utility model is, a kind of energy-conservation, wearing and tearing are little and clamp force is evenly distributed two-plate type mould clamping mechanism is provided.
Technical solution of the present utility model is, a kind of two-plate type mould clamping mechanism of following structure is provided, comprise moving platen, front template, pull bar, Quick cylinder, mould, locking nut and nut check oil cylinder, the piston end of described Quick cylinder is connected with moving platen, pull bar is provided with the lock tooth, and described locking nut is placed on the lock tooth of pull bar; Described clamping also comprises air bag component, and described air bag component is located between mould and the front template, and air bag component is provided with air-filled pore.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model structure, between mould and front template, be provided with air bag component, moving platen makes mould closed under the Quick cylinder effect, again locking nut is close to moving platen and is fastened on the lock tooth of pull bar, the nut check cylinder action also pins locking nut, thereby effectively spacing to moving platen, at this moment, the air bag component on the front template is filled with gases at high pressure, produce required clamp force, along with the carrying out of gas replenishment process, the air pressure in the air bag increases gradually, thereby promotes to be located at front template place mould matched moulds left, until complete matched moulds, in this process, the pressure in the air bag is increased to 10MPa from 0, because clamp force can be controlled by the air pressure in the air bag, clamp force is unlikely excessive, reduced energy consumption and to the wearing and tearing of part, thereby prolonged its service life, air bag component forces on the whole mould, clamp force is very even, has improved the quality of goods; After treating that injection moulding is finished, when needing the demoulding, the gas in the air bag component is bled off, just leave space between moving platen and the front template this moment, and the operation ejection cylinder is with mould ejection, and the demoulding is very convenient.
As improvement, air bag component is ring-type, and described air-filled pore has several, and several air-filled pores are evenly distributed to be on the air bag component, can guarantee like this stressed even of mould, improves the quality of injecting products.
As improvement, between mould and front template, be provided with filling channel, the one by one corresponding connection of air-filled pore of described filling channel and air bag component, air bag component inflated can kinds of schemes, default filling channel can avoid additionally setting up parts in this position, has improved simultaneously the stability of inflation.
As improvement, the air pressure of air bag component changes between 0-10MPa, and air bag component should not be too little, yet excessive air pressure also may cause the faults such as air bag component distortion, so this programme is limited to its air pressure in the one better scope, improved the reliability of product.
As improvement, be provided with the air bag backing plate between described air bag component and the front template, can effectively protect air bag component, simultaneously air bag also there is certain maintenance effect.
Description of drawings
Fig. 1 is the structural representation of two-plate type mould clamping mechanism of the present utility model.
Fig. 2 is the side view of two-plate type mould clamping mechanism of the present utility model.
As shown in the figure 1, moving platen, 2, front template, 3, pull bar, 4, Quick cylinder, 5, mould, 6, locking nut, 7, the nut check oil cylinder, 8, the lock tooth, 9, air bag component, 10, filling channel, 11, the air bag backing plate, 12, ejection cylinder.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, two-plate type mould clamping mechanism of the present utility model, comprise moving platen 1, front template 2, pull bar 3, Quick cylinder 4, mould 5, locking nut 6 and nut check oil cylinder 7, the piston end of described Quick cylinder 4 is connected with moving platen 1, pull bar 3 is provided with lock tooth 8, and described locking nut 6 is placed on the lock tooth 8 of pull bar 3; Described clamping also comprises air bag component 9, and described air bag component 9 is located between mould 5 and the front template 2, and air bag component 9 is provided with air-filled pore; Also be provided with the ejection cylinder 12 for the demoulding on the clamping.
Air bag component 9 is ring-type, and described air-filled pore has several, and several air-filled pores are evenly distributed to be on the air bag component 9 that air-filled pore can be arranged on the periphery of air bag component, also can be arranged on the side.
