Description
Technical field
The utility model relates to injection mold attachment technique field, especially a kind of wedge slide block 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 wedge slide block type two-step ejecting device.
The utility model solves the technical scheme that its technical problem adopts: a kind of wedge slide block type two-step ejecting device, comprise Bottom clamp plate and concave die cavity plate, push pedal, gripper shoe and core rod seat are installed successively between described Bottom clamp plate and concave die cavity plate, slide block is provided with between push pedal and gripper shoe, slide block is fixedly mounted in push pedal, slide block is provided with spring and hole, and push pedal central vertical is provided with the push rod passed from Bottom clamp plate; Described gripper shoe is fixed with wedge, concave die cavity plate is fixedly connected with the push rod through gripper shoe and core rod seat; Described core rod seat is built-in with core rod, and core rod center is built-in with center push rod, and center push rod is fixedly mounted on slide block through gripper shoe and core rod seat.
Further, described core rod is arranged with workpiece through one end of concave die cavity plate.
Further, described slide block is fixedly mounted in push pedal by pin.
Further, described slide block is provided with release link.
The beneficial effects of the utility model are: the utility model structure is simple, and reasonable in design, installation and maintenance is convenient, coordinate mutually between slide block with wedge and between push rod with center push rod, 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. Bottom clamp plates, 2. spring, 3. push rod, 4. push pedal, 5. pin, 6. slide block, 7. wedge, 8. push rod in figure, 9. core rod seat, 10. concave die cavity plate, 11. center push rod, 12. workpiece, 13. core rods, 14. release links, 15. gripper shoes, 16. holes.
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.
Wedge slide block type two-step ejecting device as shown in Figure 1, comprise Bottom clamp plate 1 and concave die cavity plate 10, push pedal 4, gripper shoe 15 and core rod seat 9 are installed successively between Bottom clamp plate 1 and concave die cavity plate 10, slide block 6 is provided with between push pedal 4 and gripper shoe 15, slide block 6 is fixedly mounted in push pedal 4, slide block 6 is provided with spring 2 and hole 16, and push pedal 4 central vertical is provided with the push rod 3 passed from Bottom clamp plate 1; Gripper shoe 15 is fixed with wedge 7, concave die cavity plate 10 is fixedly connected with the push rod 8 through gripper shoe 15 and core rod seat (9); Core rod seat 9 is built-in with core rod 13, and core rod 13 center is built-in with center push rod 11, and center push rod 11 is fixedly mounted on slide block 6 through gripper shoe 15 and core rod seat 9.
Core rod 13 is arranged with workpiece 12 through one end of concave die cavity plate 10; Slide block 6 is fixedly mounted in push pedal 4 by pin 5; Slide block 6 is provided with release link 14.
Push pedal 4 is equipped with slide block 6, and spring 2 promotes slide block 6 at external limit position, and wedge 7 is fixed on support plate 15.After die sinking, injector push rod 3 promotes push pedal 4 and moves, and promotes concave die cavity plate 10 and moves by workpiece 12 from core rod 13 release, but still stay in concave die cavity plate 10 under push rod 8 acts on; Push pedal 4 continues to release, and wedge 7 contacts with slide block 6, moves in compressing slide block 6, and when the hole 16 on slide block 6 and push rod 8 pairs of timings, the tail end of push rod 8 falls in the hole 16 of slide block 6, and push rod 8 stops releasing, and concave die cavity plate 10 also stops mobile.When push pedal 4 continues to release again, workpiece 12 is released by center push rod 11 from concave die cavity plate 10, completes two-step ejecting.
This wedge slide block type two-step ejecting apparatus structure is simple, and reasonable in design, installation and maintenance is convenient, coordinate mutually between slide block 6 with wedge 7 and between push rod 8 with center push rod 11, two-step ejecting is effective, improves product quality, accelerates speed of production.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
