Description
Technical field
The utility model relates to injection mold technical field, especially a kind of hydraulic cylinder Leave out thread mould.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.For the screwed plastic demoulding, the motor-driven die sinking of many employings at present.Motor-driven die sinking refers to the mould opening force that utilizes injector when die sinking or releases masterpiece is power, makes it to undercut or rotation, thus realize the automatic demoulding of screw thread by mechanical transmission part as masterpiece is used for thread forming part by rack and pinion etc.Traditional motor-driven die-sinking die complex structure, stripping result is poor, and product percent defective is high, and cost is large.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of structure simple, the hydraulic cylinder Leave out thread mould that stripping result is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of hydraulic cylinder Leave out thread mould, comprise moving platen, support plate is provided with above moving platen, cavity is provided with between moving platen and support plate, cavity is built-in with tooth bar and rotating shaft, rotating shaft one end is provided with the first gear, and the rotating shaft other end is provided with the second gear, the second wheel and rack engagement; Intert in described support plate and be provided with thread core, thread core end is installed with the 3rd gear be meshed with the first gear; Described support plate sidewall is provided with the hydraulic cylinder promoting tooth bar.
Further, described hydraulic cylinder is by support installing at support plate sidewall, and the push rod of hydraulic cylinder is fixedly connected with tooth bar.
Further, described rotating shaft is hollow pipe, and rotating shaft is built-in with the fixed axis making the first gear and the second gear steady running, and fixed axis one end is fixed on support plate, and the fixed axis other end is fixed on moving platen.
Further, bearing is provided with between described thread core and support plate.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, installation and maintenance is convenient, rotated by the transmission of rack drives first gear, the second gear and the 3rd gear, complete Leave out thread work in mould, stripping result is good, improves product quality, accelerates speed of production.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. support plate, 2. the first gear, 3. rotating shaft, 4. the second gear, 5. thread core, 6. bearing, 7. the 3rd gear, 8. moving platen, 9. tooth bar, 10. support, 11. push rods, 12. hydraulic cylinders, 13. fixed axis.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Hydraulic cylinder Leave out thread mould as shown in Figure 1, comprise moving platen 8, support plate 1 is provided with above moving platen 8, cavity is provided with between moving platen 8 and support plate 1, cavity is built-in with tooth bar 9 and rotating shaft 3, rotating shaft 3 one end is provided with the first gear 2, and rotating shaft 3 other end is provided with the second gear 4, second gear 4 and engages with tooth bar 9; Intert in support plate 1 and be provided with thread core 5, thread core 5 end is installed with the 3rd gear 7 be meshed with the first gear 2; Support plate 1 sidewall is provided with the hydraulic cylinder 12 promoting tooth bar 9.
Hydraulic cylinder 12 is arranged on support plate 1 sidewall by support 10, and the push rod 11 of hydraulic cylinder 12 is fixedly connected with tooth bar 9; Rotating shaft 3 is hollow pipe, and rotating shaft 3 is built-in with the fixed axis 13 making the first gear 2 and the second gear 4 steady running, and fixed axis 13 one end is fixed on support plate 1, and fixed axis 13 other end is fixed on moving platen 8; Bearing 6 is provided with between thread core 5 and support plate 1.
After die sinking, the push rod 11 of hydraulic cylinder 12 promotes tooth bar 9, by the transmission of the first gear 2, second gear 4 and the 3rd gear 7, thread core 5 is rotated by back-out direction, thus deviates from plastic.Plastic relies on running gate system solidifying material spline.
This hydraulic cylinder Leave out thread mould structure is simple, and reasonable in design, installation and maintenance is convenient, drive the transmission of the first gear 2, second gear 4 and the 3rd gear 7 to rotate by tooth bar 9, complete Leave out thread work in mould, stripping result is good, improve product quality, accelerate speed of production.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
