Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a high-closing mold plate double-cylinder hydraulic driving structure of a blow molding machine comprises a front closing mold plate 1, a rear closing mold plate 2, a double-cylinder driving device 3 and a synchronizing device 4; the front die plate 1 and the rear die plate 2 are arranged in parallel, and the double-oil-cylinder driving device 3 is arranged perpendicular to the rear die plate 2; one end of a double-oil-cylinder driving device 3 is fixedly connected with the rear die plate 2, and the other end of the double-oil-cylinder driving device is fixedly connected with the front die plate 1; one end of the synchronizer 4 is fixedly connected with the rear mold closing plate 2, and the other end is fixedly connected with the double-oil-cylinder driving device 3. Because the die clamping plate of the high die clamping plate is larger and heavier than the die clamping plate of the conventional blow molding product, if two driving oil cylinders are simply arranged, one more oil way needs to be added, and the machine is greatly changed. The double-oil-cylinder driving device 3 can simultaneously drive the front die plate 1 and the rear die plate 2 to move relatively without great change so as to control the opening and closing of equipment and realize the blow molding of heightened plastic products, so that the double-oil-cylinder driving device is suitable for the production of products with various specifications and has better practicability. And through the cooperation of the synchronizer 4 and the double-oil-cylinder driving device 3, the front mold closing plate and the rear mold closing plate can synchronously move, the stress is more uniform, the mold closing force is larger, the defective rate of plastic products can be effectively reduced, and the production efficiency is improved.
As shown in fig. 2 to 3, the dual cylinder driving apparatus 3 includes an upper cylinder 310, a lower cylinder 320, a thrust reversal connecting plate 330, and a connecting rod 340, wherein one end of the upper cylinder 310 is fixedly connected to the rear mold clamping plate 2, and the other end is fixedly connected to the thrust reversal connecting plate 330; the upper oil cylinder 310 and the lower oil cylinder 320 are arranged in parallel, one end of the lower oil cylinder 320 is fixedly connected with the rear mold clamping plate 2, and the other end of the lower oil cylinder is fixedly connected with the reverse thrust connecting plate 330. The diameter of the upper oil cylinder 310 is larger than that of the lower oil cylinder 320, and a throttle valve 311 is arranged at the oil outlet of the upper oil cylinder 310. For the heightened type die closing plate, if two hydraulic oil cylinders with large specifications are adopted, a large amount of oil is needed, and the production cost is increased; if adopt two hydraulic cylinder of small dimension, then can lead to thrust not enough, influence production. However, the thrust generated by hydraulic cylinders with different specifications is different, and the thrust speeds of the hydraulic cylinders are different, which may cause uneven stress on the mold clamping plate. The structure drives the mold clamping plate to open and close by arranging the hydraulic cylinders with large and small specifications, and the throttle valve 311 is arranged at the oil outlet of the upper oil cylinder 310, so that the oil return speed of the upper oil cylinder 310 can be reduced, and the oil return speed is consistent with that of the lower oil cylinder 320. The hydraulic oil cylinder has the working principle that oil is used as a working medium, power is transmitted through the pressure inside the oil, when one oil hole is filled with oil, the piston is pushed to enable the other oil hole to discharge oil, and the piston drives the piston rod to do stretching movement, and vice versa. Firstly, hydraulic oil enters the upper oil cylinder 310 and the lower oil cylinder 320 from oil inlets respectively to drive the oil cylinders to operate; then, the hydraulic oil in the upper oil cylinder 310 enters the throttle valve 311 from the oil outlet and returns to the oil tank; meanwhile, the hydraulic oil in the lower oil cylinder 320 directly returns to the oil tank from the oil outlet. In this way, the upper cylinder 310 and the lower cylinder 320 can be kept consistent, and therefore synchronous operation can be achieved.
As shown in fig. 4, the connecting rod 340 passes through the supporting base 350 and the rear clamping plate 2, and one end of the connecting rod 340 is fixedly connected with the front clamping plate 1, and the other end is fixedly connected with the reverse thrust connecting plate 330; the thrust reverser plates 330 are fixedly connected to the synchronization device 4. According to the utility model, the reverse-thrust connecting plate 330 is fixedly connected with the front die plate 1 through the connecting rod 340, when the oil cylinder works, the oil cylinder can push the rear die plate 2 and has a reaction force on the reverse-thrust connecting plate 330, so that the front die plate 1 is driven to move relatively, the die clamping force of a machine can be obviously improved, and the phenomenon of leakage caused by insufficient die clamping force during working is avoided. The supporting seat 350 is fixedly connected with the synchronizing device 4, and the supporting seat 350 and the through hole on the rear mold clamping plate 2 support the connecting rod 340.
As shown in fig. 5, the synchronizing device 4 includes a synchronizing fastener 410, a synchronizing gear 420, a rear engaging rack 430 and a reverse connecting rack 440, wherein the synchronizing fastener 410 is fixedly connected with the supporting base 350; the synchronizing gear 420 is fixed on the synchronizing fixture 410; one end of the rear closing connecting rack 430 is fixedly connected with the rear closing plate 2, and the other end is meshed with the synchronous gear 420; one end of the reverse-thrust connecting rack 440 is fixedly connected with the reverse-thrust connecting plate 330, and the other end is engaged with the synchronizing gear 420. Because the synchronous gear 420 is meshed with the rear closing connecting rack 430 and the reverse pushing connecting rack 440 at the same time, the front and rear closing plates can synchronously move after the upper oil cylinder 310 and the lower oil cylinder 320 need to keep the same thrust, so that the stable and effective work of the machine can be further ensured, and the production efficiency is improved.
As shown in fig. 6, when the blow molding machine is operating, the upper cylinder 310 and the lower cylinder 320 push the rear clamp plate 2 to move leftward, and bring the rear clamp link rack 430 to move leftward. At the same time, the upper cylinder 310 and the lower cylinder 320 push the reverse link plate 330 to move to the right. Then, the reverse pushing link plate 330 drives the front closing mold plate 1 to move to the right, and simultaneously drives the reverse pushing link rack 440 to move to the right. The synchronizing gear 420 moves clockwise to close the front and rear mold clamping plates. After the blow molding operation is completed, the upper oil cylinder 310 and the lower oil cylinder 320 push the rear mold clamping plate 2 to move rightwards, and further push the front mold clamping plate 1 to move leftwards, so that the mold clamping plate separation is realized.
