Abstract
A composite hydraulic oil cylinder of a die-casting die comprises an oil cylinder bracket (2) fixedly connected to a die (1). The end of a piston rod (4) arranged in the oil cylinder (5) can be connected with a part (3). The composite hydraulic oil cylinder is characterized in that the oil cylinder (5) consists of a main oil cylinder (6) and a secondary oil cylinder (7) which are mutually nested, a secondary oil cylinder barrel (9) is glidingly sleeved in a cylinder barrel (8) of the main oil cylinder (6), the cylinder barrel (8) is provided with a first oil hole (10) and a second oil hole (11), the cylinder bottom of the main oil cylinder (6) is provided with a limit block (14), the piston rod (4) is glidingly sleeved with the secondary oil cylinder (7), an oil passage (12) is formed between the piston rod (4) and the secondary oil cylinder (7), a section of distance is reserved between the piston rod (4) and the cylinder bottom (13) of the secondary oil cylinder, and a secondary oil cylinder gland (13) is provided with a third oil hole (15). The composite hydraulic oil cylinder has the advantages of simple and skilful structure, convenient use and flexible and reliable motion, meanwhile can provide large core-pulling force and high pulling speed, and the like.
Description
Technical field:
The utility model relates to a kind of hydraulic jack, and operation is reduced, the die casting mould complex liquid compressing cylinder of enhancing productivity in especially a kind of die casting field that is used for.
Background technique:
In the die casting industry, when the part that die casting need be finished is extracted out from mould,, need to use larger-diameter oil cylinder that the bigger power of loosing core is provided because the power of holding tightly of part is bigger at this moment, part is extracted out from mould, and when the formation of loosing core was longer, the drawing speed of major diameter oil cylinder was slower again, has a strong impact on work efficiency, if change the minor diameter oil cylinder and carry out drawing this moment, though can improve drawing speed, complex procedures has improved processing cost.Also not having now a kind ofly can provide the power of loosing core greatly, the hydraulic jack of high drawing speed simultaneously.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, ingenious, easy to use, and flexible movements, reliable can provide the die casting mould complex liquid compressing cylinder of the power of loosing core greatly, high drawing speed simultaneously.
Technical solution of the present utility model is: a kind of die casting mould complex liquid compressing cylinder, comprise the cylinder bracket 2 that can be fixedly connected on the mould 1, the end that is arranged on the piston rod 4 in the oil cylinder 5 can connect with part 3, it is characterized in that: described oil cylinder 5 is made up of mutually nested master cylinder 6 and auxiliary oil cylinder 7, flip sleeve is connected to auxiliary oil cylinder tube 9 in the cylinder barrel 8 of master cylinder 6, cylinder barrel 8 is provided with first oilhole 10 and second oilhole 11, cylinder bottom at master cylinder 6 also is provided with limiting stopper 14, piston rod 4 and auxiliary oil cylinder 7 slip sockets, and be provided with oily passage 12 between the two, leave a segment distance between piston rod 4 and the auxiliary oil cylinder cylinder bottom 13, on auxiliary oil cylinder end socket 13, also be provided with the 3rd oilhole 15.
The utility model is compared with prior art, has following advantage:
Simple in structure, ingenious, easy to operate, quick, fluent movements, stable are combined as a whole the oil cylinder of major diameter and minor diameter, when holding the part of power more greatly tightly, drawing uses the major diameter oil cylinder, provide the bigger power of loosing core, and after part was pulled out, changing the oil cylinder that uses than minor diameter again carried out drawing work, to improve drawing speed, save a large amount of drawing time, and the switching between the large and small diameter oil cylinder need not any additional process, greatly reduced cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment original state.
Fig. 2 is the working state figure of the utility model embodiment master cylinder.
Fig. 3 is the working state figure of the utility model embodiment auxiliary oil cylinder.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of die casting mould complex liquid compressing cylinder, comprise cylinder bracket 2, cylinder bracket 2 can be fixedly connected on the mould 1 by fixing bolt, and oil cylinder 5 is provided with piston rod 4, and its termination can connect mutually with part 3; Oil cylinder 5 is formed (auxiliary oil cylinder 7 can reciprocatingly slide) by mutually nested master cylinder 6 and auxiliary oil cylinder 7 together in master cylinder 6, in the cylinder barrel 8 of master cylinder 6, flip sleeve is connected to auxiliary oil cylinder tube 9, on master cylinder 6, also be provided with first oilhole 10 and second oilhole 11, and first oilhole 10 and second oilhole 11 lay respectively at cylinder barrel 8 contact with auxiliary oil cylinder tube 9 part both sides, in the cylinder bottom part of master cylinder 6, be used for limiting the limiting stopper 14 of auxiliary oil cylinder tube 8 range of movement in addition; Piston rod 4 and auxiliary oil cylinder 7 same slip sockets, and between the two, be provided with oily passage 12, between piston rod 4 and auxiliary oil cylinder cylinder bottom 13, leave a segment distance, on auxiliary oil cylinder end socket 13, also be provided with the 3rd oilhole 15.
The utility model embodiment's working procedure is as follows:
As shown in Figure 2: at first need part to be extracted from mould with the major diameter oil cylinder, oil is injected in the master cylinder 6 by first oilhole 10 that is arranged on the master cylinder 6, promote auxiliary oil cylinder tube 9 phase left movements, original master cylinder 6 interior oil that exist can be discharged by second oilhole 11, this moment, piston rod 4 was also along with the motion phase left movement of auxiliary oil cylinder tube 9, to realize the part purpose that drawing goes out from mould.
As shown in Figure 3: when oil continues to inject in the master cylinder 6, oil enters the inner chamber of auxiliary oil cylinder 7 by the oily passage 12 between piston rod 4 and auxiliary oil cylinder 7, and promote piston rod 4 continuation phase left movements (because the diameter of the auxiliary oil cylinder 7 that works this moment is less, therefore the gait of march of piston rod 4 is very fast), original oil can be discharged by the 3rd oilhole 15 under the extruding of piston rod 4 in the auxiliary oil cylinder 7, by above-mentioned two-step action, part is extracted from mould fully.
