The utility model solves the technical scheme that its technical problem adopts: a kind of restriction posture two-step ejecting device, comprise dynamic model seat and two forks, described dynamic model seat four angles are provided with guide pillar, guide pillar is fixedly connected with moving platen, moving platen is fixed with core rod seat, outside core rod seat, is provided with dynamic model cavity plate; Described dynamic model seat both sides are provided with U-shaped limit frame, and dynamic model cavity plate is installed with straight pin, and core rod seat and dynamic model cavity plate center are built-in with core rod, are provided with stopping means outside core rod seat and dynamic model cavity plate; Be provided with push pedal in the cavity that described dynamic model seat, guide pillar and moving platen are formed, push pedal be installed with push rod holder, push rod holder is provided with push rod, push rod contacts with workpiece through after moving platen and core rod; Described fork one end to be fixed in push pedal and to be positioned at the U-type groove of U-shaped limit frame, and the fork other end is connected with straight pin by spring.
Further, described stopping means comprises stop screw and limiting plate, and limiting plate is provided with chute, and stop screw is separately fixed at outside core rod seat and dynamic model cavity plate, and stop screw slides in chute.
Further, described fork one end is fixed in push pedal by rotational pin.
Further, described push pedal is installed with the push rod through dynamic model seat.
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 fork and U-shaped limit frame, 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. push pedals in figure, 3.U type limit frame, 4. push rod, 5. rotational pin, 6. guide pillar, 7. push rod holder, 8. moving platen, 9. stop screw, 10. dynamic model cavity plate, 11. core rods, 12. workpiece, 13. push rods, 14. straight pins, 15. springs, 16. forks, 17. limiting plates, 18. core rod seats.
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.
Restriction posture two-step ejecting device as shown in Figure 1, comprise dynamic model seat 1 and two forks 16, dynamic model seat 1 four angles are provided with guide pillar 6, guide pillar 6 are fixedly connected with moving platen 8, moving platen 8 is fixed with core rod seat 18, outside core rod seat 18, is provided with dynamic model cavity plate 10; Dynamic model seat 1 both sides are provided with U-shaped limit frame 3, dynamic model cavity plate 10 are installed with straight pin 14, and core rod seat 18 and dynamic model cavity plate 10 center are built-in with core rod 11, are provided with stopping means outside core rod seat 18 and dynamic model cavity plate 10; Be provided with push pedal 2 in the cavity that dynamic model seat 1, guide pillar 6 and moving platen 8 are formed, push pedal 2 be installed with push rod holder 7, push rod holder 7 be provided with push rod 13, push rod 13 contacts with workpiece 12 through after moving platen 8 and core rod 11; Fork 16 one end to be fixed in push pedal 2 and to be positioned at the U-type groove of U-shaped limit frame 3, and fork 16 other end is connected with straight pin 14 by spring 15.
Stopping means comprises stop screw 9 and limiting plate 17, and limiting plate 17 is provided with chute, and stop screw 9 is separately fixed at outside core rod seat 18 and dynamic model cavity plate 10, and stop screw 9 slides in chute; Fork 16 one end is fixed in push pedal 2 by rotational pin 5; Push pedal 2 is installed with the push rod 4 through dynamic model seat 1.
