A kind of secondary demolding mechanism for processing barb
Technical field
The present invention relates to a kind of secondary demolding mechanism for processing barb, belonging to mould emptier technical field.
Background technology
Traditional barb demoulding mechanism generally all adopts shutter to drive, and can rebound after having arrived stroke, causes barb amount to pull open value different; affect the shaping quality of barb; as shown in Figure 1 be the structural representation of traditional barb demoulding mechanism, wherein 11-board push rod, 12-shutter.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, proposing a kind of secondary demolding mechanism for processing barb, realizing barb precision form.
The present invention adopts following technical scheme: a kind of secondary demolding mechanism for processing barb; it is characterized in that; comprise barb, thimble, oil cylinder, board push rod, ejector retainner plate; described oil cylinder is fixedly installed on described ejector retainner plate; described board push rod is arranged at the below of described ejector retainner plate; described thimble is arranged at the top of described oil cylinder, and the piston of described oil cylinder is connected with the lower end of described thimble, and described barb is connected with the upper end of described thimble.
The beneficial effect that the present invention reaches: the present invention reduces shutter, adopts oil cylinder to be fixed on the ingehious design of ejector retainner plate, realizes barb bending amount and fix, and ensure that barb realizes the accurate demoulding smoothly by Design of Dies.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 2 is the structural representation of the top view of a kind of secondary demolding mechanism for processing barb of the present invention, Fig. 3 is the internal structure schematic diagram of the front view of a kind of secondary demolding mechanism for processing barb of the present invention, Fig. 4 is the external structure schematic diagram of the front view of a kind of secondary demolding mechanism for processing barb of the present invention, the present invention proposes a kind of secondary demolding mechanism for processing barb, it is characterized in that, comprise barb 21, thimble 22, oil cylinder 23, board push rod 24, ejector retainner plate 25, oil cylinder 23 is fixedly installed on ejector retainner plate 25, board push rod 24 is arranged at the below of ejector retainner plate 25, thimble 22 is arranged at the top of oil cylinder 23, the piston of oil cylinder 23 is connected with the lower end of thimble 22, barb 21 is connected with the upper end of thimble 22.
Fig. 5 is the configuration state schematic diagram that the board push rod of a kind of secondary demolding mechanism for processing barb of the present invention once ejects; board push rod 24 jack-up ejector retainner plate 25 is to stroke limit position; drive oil cylinder 23 move upward promote thimble 22 make barb 21 occur bending distortion, complete a demoulding.
Fig. 6 is the configuration state schematic diagram of the board push rod Double-ejection of a kind of secondary demolding mechanism for processing barb of the present invention, and the piston of oil cylinder 23 promotes thimble 22 jack-up barb and completes the secondary demoulding.
Fig. 7 is the process schematic of barb bending of the present invention, and barb 21 first moves downward, and then completes whole bending process to left movement.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
