Description
Technical field
The present invention relates to clasp mould mechanism field, particularly relate to the controlled clasp mould mechanism of a kind of thermoforming machine.
Background technology
Existing die opening/closing mechanism of thermoforming machine can be divided into fluid pressure type, hydraulic pressure-mechanical type and electronic-mechanical type three class by its manner of execution.
Fluid pressure type clasp mould mechanism is the direct locking die of pressure relying on liquid, and after the pressure releases of liquid, clamp force also disappears thereupon.Fluid pressure type clasp mould mechanism can be divided into single cylinder direct press type, liquid-filled, booster-type clasp mould mechanism etc. by the action mode of hydraulic cylinder.Fluid pressure type clasp mould mechanism structure is simple; can realize larger opening mould-closing stroke; and larger clamp force can be obtained; but defects such as having in its folding mold process that velocity perturbation is large, impulsive force is large, be difficult to accurately to control and machining accuracy is high; these defects make that mechanism efficiency is low, big energy-consuming, not environmentally; and when mold clamping force is larger, required hydraulic cylinder volume is comparatively large, is difficult to manufacture.
Hydraulic pressure-mechanical open clamping is power source with hydraulic cylinder, between hydraulic cylinder and template, increase connecting-rod force increasing device.Be characterized in having auto-lock function, namely when after mold-locked, even if oil pressure is cancelled, clamp force also can not disappear.Because linkage has boosting function, so larger clamp force can be obtained with less oil cylinder.But this clasp mould mechanism complex structure, volume are large and moving platen inertia force is large, be difficult to realize improving the demand opening closure pressing speed.
The link-type clasp mould mechanism that electronic-mechanical open clamping can be divided into the cam-actuated link-type clasp mould mechanism of biconjugate and ball-screw to drive by its mechanical structure form.
Biconjugate cam-actuated link-type clasp mould mechanism drives two pairs of conjugate cams to rotate by same motor, and drivening rod swings, and realizes moving up and down and overturning of workbench.The motor of this clasp mould mechanism can rotate continuously, and it is convenient to control.But conjugate cam linkage complex structure, by the restriction of cam face, the very flexible of mechanism, and workbench inertia force when overturning is large, clasp mould mechanism is difficult to realize high-speed cruising.
The link-type clasp mould mechanism that ball-screw drives adopts driven by servomotor ball screw, and drivening rod mechanism realizes folding mould, can control open mould assembling action more accurately.But moving up and down of this clasp mould mechanism workbench, needs to transfer realization by the positive and negative of servomotor, due to the impact by inertia force and motor speed, machine is difficult to high-speed cruising, and ball screw easily weares and teares, and affects service life of a machine.
