Background technology
Two kinds of traditional injection machine thimble cylinder structures are: one, common single cylinder structure; Two, Bing Lian heavy wool cylinder structure mostly is two oil cylinders side by side.
The shortcoming of first kind of structure is: because the oil cylinder area is certain, thimble power is restricted.If strengthen thimble power, under the certain situation of pressure, can only strengthen cylinder diameter, cause overall structure excessive, thimble speed reduces, and has reduced operating efficiency when increasing equipment cost.
The shortcoming of second kind of structure is: the parallel connection of heavy wool cylinder makes syndeton complicated, is difficult to obtain reasonable Arrangement under the structure space condition of limited, brings inconvenience to assembling simultaneously.
Existing injection machine is as providing the requirement that ejects of high speed and high thimble power simultaneously, and the thimble cylinder structure is necessary to improve above defective.
The utility model content
The purpose of this utility model is, overcomes the defective that the above-mentioned background technology exists, and provides a kind of and can effectively improve thimble power, accelerates thimble speed, simultaneously the thimble cylinder structure of the simple compact injection machine of profile.
For reaching above-mentioned purpose, the utility model provides a kind of thimble cylinder structure of injection machine, comprises cylinder body, oil cylinder bonnet and oil cylinder protecgulum, quick piston and piston rod.Piston is located in the cylinder body and with piston rod and is fastened fast, and piston rod passes the oil cylinder protecgulum and stretches out cylinder body, and the piston rod front end is installed with the thimble guide plate.The thimble cylinder structure also comprises the high pressure piston that is resisted against between oil cylinder protecgulum and the thimble guide plate and is sheathed on piston rod, the oil cylinder protecgulum offer be used to pressure oil into so that promote forward high pressure piston first before hydraulic fluid port, high pressure piston promotes the thimble guide plate forward.
As improvement of the present utility model, the thimble cylinder structure of described injection machine also comprises a portable plate between oil cylinder protecgulum and thimble guide plate, the relative oil cylinder protecgulum of portable plate maintains static all the time, high pressure piston has main part and protrudes out the limiting section that forms laterally by the main part rear portion, portable plate offers the body groove of the main part of sheathed high pressure piston, the body groove rear portion outwards protrudes out and forms the stopper slot that matches with the limiting section of high pressure piston, and the limiting section of high pressure piston can move reciprocatingly between the stopper slot of oil cylinder protecgulum and portable plate.
As mentioned above, the thimble cylinder structure of the utility model injection machine promotes the thimble guide plate by the high pressure piston that increases, and has effectively improved thimble power, has accelerated thimble speed.In addition, cooperating between the stopper slot by portable plate and the limiting section of high pressure piston makes goods under loosening situation, high pressure piston separates with the thimble guide plate, piston promotes thimble guide plate rapid movement separately fast, makes goods fast and safely eject, and avoids producing bigger impulsive force.The utility model profile is simply compact, and design and installation is convenient, and cost performance is able to very big lifting, has well satisfied the requirement of actual production to thimble.
Description of drawings
In Figure of description:
Fig. 1 is the thimble cylinder structure schematic diagram of the utility model injection machine.
The description of reference numerals of each element is as follows among the figure:
Limiting section 62 thimble guide plates 7
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being reached purpose and effect, enumerate below that embodiment and conjunction with figs. are detailed gives explanation.
See also Fig. 1, the thimble cylinder structure 100 of the utility model injection machine comprises cylinder body 1, oil cylinder bonnet 2 and oil cylinder protecgulum 3, quick piston 4 and piston rod 5, high pressure piston 6, thimble guide plate 7 and portable plate 8.Wherein, oil cylinder bonnet 2 is connected with cylinder body by screw thread and is welded into as a wholely, and offers the back hydraulic fluid port 21 that communicates with cylinder body.Piston 4 is located in the cylinder body 1 and is anchored on piston rod 5 rear ends fast.Cylinder body 1 front end is fixed on the oil cylinder protecgulum 3 more together by behind the sheathed connection one oil cylinder locknut 9 of screw thread.Piston rod 5 passes oil cylinder protecgulum 3 and stretches out cylinder body 1, and piston rod 5 front ends connect thimble guide plate 7, and thimble guide plate 7 front ends are connected with a clamp nut 10, and are fixed on piston rod 5 front ends by this clamp nut 10.
When thimble advances, the first preceding hydraulic fluid port 32 of the back hydraulic fluid port 21 of oil cylinder bonnet 2 and oil cylinder protecgulum 3 advances pressure oil simultaneously simultaneously, fast piston 4, high pressure piston 6 are simultaneously stressed, and this just is equivalent to strengthen the lifting surface area of piston, has strengthened thimble power under the certain situation of system pressure.Piston 4 travels forward by piston rod 5 promotion thimble guide plates 7 fast, and high pressure piston 6 directly promotes thimble guide plates 7 and travels forward.After a bit of distance of thimble guide plate 7 operations, in die cavity, also moved corresponding distance and loosening of goods, goods eject required thimble power and significantly reduce, at this moment, the limiting section 62 of high pressure piston 6 is resisted against stopper slot 82 diapires of portable plate 8 just, and separate with thimble guide plate 7, the first preceding hydraulic fluid port 32 of oil cylinder protecgulum 3 also no longer advances pressure oil.The less quick piston 4 of lifting surface area just promotes thimble guide plate 7 rapid movements separately, and goods eject fast.
When thimble moved back, the second preceding oilhole 33 that communicates with cylinder body 1 on the oil cylinder protecgulum 3 advanced pressure oil, promoted quick piston 4 drive thimble guide plates 7 and retreated fast, leaned against high pressure piston 6 front ends up to thimble guide plate 7, drove high pressure piston 6 and return original position together.
As mentioned above, the thimble cylinder structure 100 of the utility model injection machine promotes thimble guide plate 7 by the high pressure piston 6 that increases, and has effectively improved thimble power, has accelerated thimble speed.In addition, cooperating between the stopper slot 82 by portable plate 8 and the limiting section 62 of high pressure piston 6, make goods under loosening situation, high pressure piston 6 separates with thimble guide plate 7, piston 4 promotes thimble guide plate 7 rapid movements separately fast, make goods fast and safely eject, avoid producing bigger impulsive force.The utility model profile is simply compact, and design and installation is convenient, and cost performance is able to very big lifting, has well satisfied the requirement of actual production to thimble.
Above illustrated embodiment only is used for conveniently illustrating the utility model, be not that the utility model is done any pro forma restriction, have in the technical field under any and know the knowledgeable usually, if in the scope that does not break away from technical characterictic that the utility model is carried, utilize technology contents that the utility model discloses to do the local equivalent embodiment that changes or modify, and do not break away from technical characterictic content of the present utility model, all still belong in the scope of the utility model technical characterictic.
