Abstract
The utility model provides an injection machine embedded extrusion mechanism, which comprises a piston, a piston rod, a cylinder, a front cover, a front cover copper sleeve, a rear cover and a rear cover copper sleeve, wherein the piston rod is fixedly connected with the piston which is provided with a seal ring to form an integral body in order to be matched with the cylinder, one end of the cylinder is connected with the front cover and the front cover copper sleeve, the other end is matched with the rear cover which is connected with a movable template via a bolt in order to fix the whole extrusion mechanism on the movable template, the rear cover is fixed with the rear cover copper sleeve and a stressed top, the front cover, the front cover copper sleeve and one part of the cylinder are embedded into the movable template, the big-end of the piston rod is extended out from the front cover copper sleeve, and the small-end of the piston rod is extended out from the rear cover copper sleeve. After adopting the technique scheme, the utility model is differ from a common separating structure which enables the extrusion mechanism to be connected with the movable template via a supporting rod, one part of the extrusion mechanism of the utility model is embedded into the movable template, thereby enabling occupied space of the whole extrusion mechanism to be reduced grandly, therefore, the extrusion stroke is capable of being longer than the common separating type.
Description
Technical field
The utility model relates to a kind of injection machine technical field, particularly a kind of ejecting mechanism that is installed on the long ejection stroke of toggle formula locking injection machine.
Background technology
General toggle formula locking injection machine, because toggle restriction spatially, adopt separate type as ejecting mechanism, its ejection stroke can be limited, when running into the mould that some need long ejection stroke, the injection machine that adopts this structure often other all parameters all meets but and only can not meet the demands because of the deficiency of ejection stroke, causes being forced to select for use the machine of bigger specification, causes waste.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, for toggle formula locking injection machine provides a kind of have long ejection stroke and the more stable embedded ejecting mechanism of injection machine of operation.
For achieving the above object, the technical scheme that the utility model provides is: comprise piston, piston rod, cylinder barrel, protecgulum, protecgulum copper sheathing, bonnet, the bonnet copper sheathing, piston rod is fixedly connected into integral body with the piston of band sealing ring, cooperate with cylinder barrel, cylinder barrel one end is connected with protecgulum and protecgulum copper sheathing, and the other end cooperates with bonnet, and bonnet is connected with moving die plate by bolt, thereby whole ejecting mechanism is fixed on the moving die plate, bonnet copper sheathing and gland are housed on the bonnet; Described protecgulum, the part of protecgulum copper sheathing and cylinder barrel embed in the moving die plate; Described piston rod divides big or small two ends, and big end stretches out from the protecgulum copper sheathing, and small end stretches out from the bonnet copper sheathing.
After adopting technique scheme, be different from generally with cramp bar ejecting mechanism is connected in separate type on the moving die plate, the part of this ejecting mechanism is embedded in the moving die plate, thereby whole ejecting mechanism occupation space is greatly reduced, so that its ejection stroke can be accomplished is longer than general separate type.In addition, compare to the separate type ejecting mechanism, this structure is except can obtaining longer ejection stroke, and because of piston rod has two shafts, all there are supporting and guiding in both sides, and therefore motion is also more steady.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label among the figure is: the 1-piston rod; 2-bonnet copper sheathing; The 3-gland; The 4-bonnet; The 5-piston; The 6-bolt; The 7-cylinder barrel; The 8-protecgulum; 9-protecgulum copper sheathing; The 10-moving die plate.
The specific embodiment
The utility model is described in further detail below in conjunction with above-mentioned accompanying drawing.
As shown in Figure 1, piston rod 1 is fixedly connected into integral body with the piston 5 of band sealing ring, cooperate with cylinder barrel 7, cylinder barrel 7 one ends are connected with the protecgulum 8 and the protecgulum copper sheathing 9 that embed moving die plate, the other end cooperates with bonnet 4, bonnet 4 is connected with moving die plate 10 by bolt 6, thereby whole ejecting mechanism is fixed on the moving die plate 10.Bonnet copper sheathing 2 and gland 3 are housed on the bonnet 4.Described piston rod 1 is the two-way ram bar, divides big or small two ends, and big end stretches out from protecgulum copper sheathing 9, makes knock-pin and uses; Small end stretches out from bonnet copper sheathing 2, is used for stroke detection.
Claims (2)
1. the embedded ejecting mechanism of injection machine comprises piston, piston rod, cylinder barrel, protecgulum, protecgulum copper sheathing, bonnet, the bonnet copper sheathing is characterized in that: piston rod is fixedly connected into integral body with the piston of band sealing ring, cooperate with cylinder barrel, cylinder barrel one end is connected with protecgulum and protecgulum copper sheathing, and the other end cooperates with bonnet, and bonnet is connected with moving die plate by bolt, thereby whole ejecting mechanism is fixed on the moving die plate, bonnet copper sheathing and gland are housed on the bonnet; Described protecgulum, the part of protecgulum copper sheathing and cylinder barrel embeds in the moving die plate.
2. the embedded ejecting mechanism of a kind of injection machine according to claim 1, it is characterized in that: described piston rod divides big or small two ends, and big end stretches out from the protecgulum copper sheathing, and small end stretches out from the bonnet copper sheathing.
