Description

Centering block drawplate type two-step ejecting device
Technical field
The utility model relates to injection mold attachment technique field, especially a kind of centering block drawplate type two-step ejecting device.
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.Sometimes, because plastic parts shape is special or the needs of the production automation, after a demoulding projecting motion, plastic is still difficult to take out from die cavity or can not Automatic-falling, must increase a demoulding projecting motion again, just can make the plastic demoulding; Sometimes in order to avoid plastic when a demoulding is released is stressed excessive, also adopt the secondary demoulding to release, to ensure the quality of plastic, this kind of mould emptier is called two-step ejecting device.Traditional two-step ejecting apparatus structure is complicated, and release weak effect, 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 deficiency in prior art, provides a kind of structure simple, releases effective centering block drawplate type two-step ejecting device.
The utility model solves the technical scheme that its technical problem adopts: a kind of centering block drawplate type two-step ejecting device, comprise moving platen and solid plate, gripper shoe, dynamic model cavity plate and cover half cavity plate is disposed with between described moving platen and solid plate, gripper shoe is arranged on moving platen after being fixedly connected with dynamic model cavity plate, and cover half cavity plate is fixedly connected with solid plate; Described gripper shoe is provided with interconnective centering block and spring, outside cover half cavity plate, arm-tie is installed; Described moving platen center is provided with small mould core, and small mould core is arranged with workpiece through after gripper shoe and dynamic model cavity plate, is arranged with core rod outside workpiece; Be provided with push pedal outside described moving platen, be provided with push rod fixed block between moving platen and push pedal, push rod fixed block is fixedly mounted in push pedal; Described push pedal is provided with two push rods, push rod contacts with workpiece through after push rod fixed block, moving platen, gripper shoe and dynamic model cavity plate successively.
Further, distance screws is provided with between described gripper shoe and dynamic model cavity plate.
Further, described core rod is positioned at cover half cavity plate and solid plate inside center.
Further, described push rod is positioned at small mould core both sides.
The beneficial effects of the utility model are: the utility model structure is simple, and reasonable in design, installation and maintenance is convenient, and by cooperatively interacting between centering block and arm-tie, two-step ejecting is effective, improves product quality, accelerates speed of production.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. dynamic model seat, 2. moving platen, 3. centering block, 4. spring, 5. arm-tie, 6. push pedals, 7. push rod fixed block, 8. solid plate, 9. core rod, 10. workpiece in figure, 11. small mould cores, 12. cover half cavity plate, 13. dynamic model cavity plate, 14. distance screws, 15. gripper shoes, 16. push rods.
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.
Centering block drawplate type two-step ejecting device as shown in Figure 1, comprise moving platen 2 and solid plate 8, gripper shoe 15, dynamic model cavity plate 13 and cover half cavity plate 12 is disposed with between moving platen 2 and solid plate 8, gripper shoe 15 is arranged on moving platen 2 after being fixedly connected with dynamic model cavity plate 13, and cover half cavity plate 12 is fixedly connected with solid plate 8; Gripper shoe 15 is provided with interconnective centering block 3 and spring 4, arm-tie 5 is installed outside cover half cavity plate 12; Moving platen 2 center is provided with small mould core 11, and small mould core 11 is arranged with workpiece 10 through after gripper shoe 15 and dynamic model cavity plate 13, is arranged with core rod 9 outside workpiece 10; Be provided with push pedal 6 outside moving platen 2, be provided with push rod fixed block 7 between moving platen 2 and push pedal 6, push rod fixed block 7 is fixedly mounted in push pedal 6; Push pedal 6 is provided with two push rods 16, push rod 16 contacts with workpiece 10 through after push rod fixed block 7, moving platen 2, gripper shoe 15 and dynamic model cavity plate 13 successively.
Distance screws 14 is provided with between gripper shoe 15 and dynamic model cavity plate 13; Core rod 9 is positioned at cover half cavity plate 12 and solid plate 8 inside center; Push rod 16 is positioned at small mould core 11 both sides.
After die sinking, moving platen 2 moves to left, and the arm-tie 5 being fixed on cover half cavity plate 12 side pulls the centering block 3 being arranged on dynamic model side, makes centering block 3 boost dynamic model cavity plate 13 and workpiece 10 is deviate from from core rod 9, completes first time release; Moving platen 2 continues to move to left, and push rod 16 is released in driven for workpiece 10 model cavity plate 13, completes second time and releases.The setting of spring 4 is that centering block 3 is contacted all the time with dynamic model cavity plate 13.
