A kind of 0 degree of mould emptier for hub before large-scale tv
Technical field
The utility model relates to a kind of 0 degree of mould emptier for hub before large-scale tv, belongs to product stripping technical field.
Background technology
Before large-scale tv, hub structure is complicated, and the general mode of compression molding that adopts is processed, but requires higher machining accuracy in knockout course, is therefore necessary to design the mould emptier that a kind of structure is simple, be easy to operation.
Utility model content
The purpose of this utility model is the defect overcoming prior art existence, proposes a kind of 0 degree of mould emptier for hub before large-scale tv.
The utility model adopts following technical scheme: a kind of 0 degree of mould emptier for hub before large-scale tv, it is characterized in that, comprise mold, push pedal, described push pedal is arranged at the top of described mold, the bilateral symmetry of described push pedal is provided with two and ejects frame, and the centre of described push pedal is provided with hub before TV; Core is provided with in the middle of the upper end of described mold, before described core and described TV, hub is in mating connection, the bottom of described mold is provided with ejector retainner plate, described ejector retainner plate is symmetrically arranged with some to thimble, the upper end bilateral symmetry of described mold is provided with two oil cylinders, eject the below of frame described in described oil cylinder is positioned at, the piston of described oil cylinder contacts with the lower end of described push pedal.
The beneficial effect that the utility model reaches: the utility model completes a demoulding by oil cylinder and push pedal, before thimble ejects TV, hub completes the secondary demoulding, achieve 0 degree of smooth demoulding of hub before TV, have structure simple, design ingenious, practical advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of matched moulds state of the present utility model.
Fig. 2 is the structural representation after a demoulding of the present utility model.
Fig. 3 is the structural representation after the secondary demoulding of the present utility model.
The implication marked in figure: 1-ejector retainner plate, 2-thimble, 3-oil cylinder, 4-push pedal, 5-ejects frame, hub before 6-TV, 7-core, 8-mold.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Fig. 1 is the structural representation of matched moulds state of the present utility model, the utility model proposes a kind of 0 degree of mould emptier for hub before large-scale tv, it is characterized in that, comprise mold 8, push pedal 4, push pedal 4 is arranged at the top of mold 8, the bilateral symmetry of push pedal 4 is provided with two and ejects frame 5, and the centre of push pedal 4 is provided with hub 6 before TV; Core 7 is provided with in the middle of the upper end of mold 8, before core 7 and TV, hub 6 is in mating connection, the bottom of mold 8 is provided with ejector retainner plate 1, ejector retainner plate 1 is symmetrically arranged with some to thimble 2, the upper end bilateral symmetry of mold 8 is provided with two oil cylinders 3, oil cylinder 3 is positioned at the below ejecting frame 5, and the piston of oil cylinder 3 contacts with the lower end of push pedal 4.
Fig. 2 is the structural representation after a demoulding of the present utility model, and first, before oil cylinder 3 drives push pedal 4 TV, hub 6 moves upward in push pedal, and before making TV, hub 6 inside line departs from core 7, and realize hollow, before being beneficial to TV, hub 6 inside contracts.
Fig. 3 is the structural representation after the secondary demoulding of the present utility model, and then, after before TV, hub 6 inside contracts, before ejector retainner plate 1 drives thimble 1 to eject TV, hub 6 is to complete the demoulding; 0 degree refer to twice knockout course TV before hub be and move straight up.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
