Abstract
An anti-loosening connecting structure for an ejection cylinder and an ejection plate of a press casting cylinder comprises an ejection cylinder piston rod (1) and an ejection push plate (2) sleeved on a step section (7) of the ejection cylinder piston rod (1), and is characterized in that a concave groove (9) is arranged on the step section (7), a mounting semi clamp ring (5) is clamped in the concave groove (9), a gland (6) is sleeved on the step section (7), the inner step surface of the gland (6) pushes against the outer end surface of the semi clamp ring (5), the inner end surface of the semi clamp ring (5) pushes against the end surface of the ejection push plate (2), the gland (6) is fixedly connected with the ejection push plate (2) by a connecting bolt (8). The anti-loosening connecting structure has simple structure and small axial size, is reliable in connection, and cannot generate movement interference.
Description
Technical field
The utility model relates to a kind of die casting machine, the syndeton of liftout tank in the die casting machine and liftout plate especially, the locking syndeton of specifically a kind of die casting machine liftout tank and liftout plate.
Background technology
As everyone knows, the ejecting mechanism of middle-size and small-size die casting machine is made up of a hydraulic jack and liftout plate, and this mechanism is installed in the back side of dynamic model installing plate, and can not interfere with matched moulds toggle motion, so this mechanism must be very compact.Commonly used at present have pairs of anti-loose nut structure and nut to add the floor clip structure, and like Fig. 1, shown in 2, Fig. 1 adopts two round nuts 3 to realize locking purpose; This structure not only axial dimension is big; And very easily vibrated and become flexible, Fig. 2 is that to adopt a round nut 3 and floor clip 4 to realize locking, these two kinds of structures are when die casting machine frequently ejects workpiece; Under vibration environment, work for a long time, round nut becomes flexible easily, comes off.
Summary of the invention
The purpose of the utility model is to be prone to when being connected with hydraulic cylinder piston rod fix the problem that comes off with nut loosening because of the vibration appearance to existing die casting machine liftout plate, designs a kind ofly can bear the die casting machine liftout tank that frequent vibration can not become flexible and the locking syndeton of liftout plate for a long time.
The technical scheme of the utility model is:
The locking syndeton of a kind of die casting machine liftout tank and liftout plate; It comprises liftout tank piston rod 1, ejects push pedal 2; Eject push pedal 2 and be sleeved on the step section 7 of liftout tank piston rod 1, it is characterized in that described step section 7 is provided with groove 9, half snap ring 5 is installed is installed in the groove 9; Gland 6 is sleeved on the step section 7; The interior step surface of gland 6 and the outer face of half snap ring 5 offset, and the inner face of half snap ring 5 offsets with the end face that ejects push pedal 2, described gland 6 through connecting bolt 8 with eject push pedal 2 and be fixedly linked.
Described half snap ring 5 is arranged in the mount grooves 9 that ejects in the push pedal 2.
The beneficial effect of the utility model:
The utility model is simple in structure, connects reliable.
The utility model axial dimension is little, can not produce movement interference.
Description of drawings
Fig. 1 is existing pairs of anti-loose nut structural representation.
Fig. 2 is the anti-loose structure sketch map that existing nut adds floor clip.
Fig. 3 is the anti-loose structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 3.
The locking syndeton of a kind of die casting machine liftout tank and liftout plate; It comprises liftout tank piston rod 1, ejects push pedal 2; Eject push pedal 2 and be sleeved on the step section 7 of liftout tank piston rod 1, described step section 7 is provided with groove 9, half snap ring 5 is installed is installed in the groove 9; Gland 6 is sleeved on the step section 7; The interior step surface of gland 6 and the outer face of half snap ring 5 offset, and the inner face of half snap ring 5 offsets with the end face that ejects push pedal 2, described gland 6 through connecting bolt 8 with eject push pedal 2 and be fixedly linked.In order to reduce axial dimension, can eject mount grooves 9 of processing in the push pedal 2 during practical implementation, make during assembling half snap ring 5 with all with the large part of gland 6 in mount grooves 9.Ejecting push pedal 2 during work relies on the effect of half snap ring 5 to be positioned on the piston rod 1; And half snap ring 5 receives the constraint of cover plate 6 and can from the groove on the piston rod 1, not come off; Having guaranteed to eject push pedal 2 is fixed on the piston rod 1 all the time; Gland 6 through a plurality of connecting bolts 8 with eject push pedal 2 and link to each other and can not separate with it, thereby guaranteed the reliability that connects.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
Claims (2)
1. the locking syndeton of die casting machine liftout tank and liftout plate; It comprises liftout tank piston rod (1), ejects push pedal (2); Eject push pedal (2) and be sleeved on the step section (7) of liftout tank piston rod (1), it is characterized in that described step section (7) is provided with groove (9), half snap ring (5) is installed is installed in the groove (9); Gland (6) is sleeved on the step section (7); The outer face of the interior step surface of gland (6) and half snap ring (5) offsets, and the inner face of half snap ring (5) offsets with the end face that ejects push pedal (2), and described gland (6) is through connecting bolt (8) and eject push pedal (2) and be fixedly linked.
2. the locking syndeton of die casting machine liftout tank according to claim 1 and liftout plate is characterized in that described half snap ring (5) is arranged in the mount grooves (9) that ejects in the push pedal (2).
