Abstract
The utility model provides a double-cylinder pressurizing mold closing mechanism which comprises a pressurizing oil cylinder, a mold moving oil cylinder and a moveable mould. The front end face of the pressurizing oil cylinder is hermetically connected with the rear end face of the mold moving oil cylinder. A hole where a first piston rod of the pressurizing oil cylinder passes through is arranged on the rear end face of the mold moving oil cylinder. The moveable mould is fixedly connected at the end of a second piston rod of the mold moving oil cylinder. The double-cylinder pressurizing mold closing mechanism provided by the utility model is compact in structure, and the pressurizing oil cylinder is additionally arranged at the rear end of the mold moving oil cylinder, so that the oil pressure is increased and the mold locking pressure is improved, therefore, the product quality in the injection process is guaranteed.
Description
Technical field
The utility model relates to a kind of mold closing mechanism, particularly a kind of twin-tub booster-type mold closing mechanism.
Background technology
Injection machine is when shifting formwork and locked mode; the general form that all adopts hydraulic cylinder, the size of its clamp force directly has influence on the quality of injecting products, in injection moulding process; the quality of injecting products usually can occur reducing not owing to clamp force, its reason is that thrust hydraulic cylinder is inadequate.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of twin-tub booster-type mold closing mechanism that improves locked mode pressure.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of twin-tub booster-type mold closing mechanism, comprise pressurizing cylinder 2, mould shifting oil cylinder 4 and moving platen 7, described pressurizing cylinder 2 front end end faces are connected with described mould shifting oil cylinder 4 rear end end face seals, described mould shifting oil cylinder 4 rear end end faces are provided with the hole that the first piston bar 14 for pressurizing cylinder 2 passes, and described moving platen 7 is fixedly connected on the second piston rod 15 ends of described mould shifting oil cylinder 4.
Further, described pressurizing cylinder 2 comprises the first back cavity 1 and the first ante-chamber 3 that is divided into by first piston, and described the first back cavity 1 is provided with the first oil-in 13, and described the first ante-chamber 3 is provided with the first oil-out 12.
Further, described mould shifting oil cylinder 4 comprises the second back cavity 10 and the second ante-chamber 9 that is divided into by the second piston, and described the second back cavity 10 is provided with the second oil-in 11, and described the second ante-chamber 9 is provided with the second oil-out 8.
(3) beneficial effect
The utility model twin-tub booster-type mold closing mechanism compact conformation has been set up pressurizing cylinder in the mould shifting oil cylinder rear end, has increased oil pressure, has improved locked mode pressure, thereby has guaranteed the product quality in injection moulding process.
Description of drawings
Fig. 1 is the structural representation of the utility model twin-tub booster-type mold closing mechanism.
The specific embodiment
Consult Fig. 1, the utility model provides a kind of twin-tub booster-type mold closing mechanism, comprise pressurizing cylinder 2, mould shifting oil cylinder 4 and moving platen 7, pressurizing cylinder 2 front end end faces are connected with mould shifting oil cylinder 4 rear end end face seals, mould shifting oil cylinder 4 rear end end faces are provided with the hole that the first piston bar 14 for pressurizing cylinder 2 passes, moving platen 7 is fixedly connected on the second piston rod 15 ends of described mould shifting oil cylinder 4, and mould shifting oil cylinder front end end is provided with sealing ring 5 and gland 6; Pressurizing cylinder 2 comprises the first back cavity 1 and the first ante-chamber 3 that is divided into by first piston, is provided with the first oil-in 13 at the first back cavity 1, is provided with the first oil-out 12 at the first ante-chamber 3; Mould shifting oil cylinder 4 comprises the second back cavity 10 and the second ante-chamber 9 that is divided into by the second piston, is provided with the second oil-in 11 at the second back cavity 10, is provided with the second oil-out 8 at the second ante-chamber 9.During locked mode, 11 oil-feeds of the second oil-in promote the second piston rod 15 forward, and simultaneously the first oil-in 13 oil-feeds promote first piston bar 14 forward, thereby increase the oil pressure in the second back cavity 10, have increased clamp force; When dividing mould, the first oil-out 12 and 8 oil-feeds of the second oil-out retreat piston.The utility model twin-tub booster-type mold closing mechanism compact conformation has been set up pressurizing cylinder in the mould shifting oil cylinder rear end, has increased oil pressure, has improved locked mode pressure, thereby has guaranteed the product quality in injection moulding process.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
