Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment 1:
As shown in Figure 1, a kind of mould can protecting shaping blank outer wall, comprise base 12, the top of described base 12 is provided with cover half seat 1, moving platen 7 is provided with between cover half seat 1 and base 12, the top of moving platen 7 contacts with the bottom of cover half seat 1, support plate 13 is provided with between moving platen 7 and base 12, the top of support plate 13 contacts with the bottom of moving platen 7, the bottom of support plate 13 and the tip contact of base 12, through hole is provided with in moving platen 7, punch 4 is provided with in through hole, the bottom of punch 4 and the tip contact of support plate 13, the top indent of punch 4 forms groove one, push rod 9 is provided with in punch 4, push rod 9 one end is arranged in base 12, the other end is through being arranged in groove one after support plate 13 and punch 4, push rod 9 outer wall is sheathed with spring 10, the two ends of spring 10 are separately positioned in punch 4 and base 12 through after support plate 13, mold insert 3 is provided with in groove one, mold insert 3 is linked in push rod 9 and is arranged on the outer wall of the part in groove one, the outer wall of moving platen 7 is provided with side core 15, side core 15 one end is through moving platen 7 and rear mold insert 3 wall contacts with being arranged in groove one of punch 4, the outer wall of side core 15 is vertically fixed with bearing pin 16, it is outside that bearing pin 16 is arranged on moving platen 7, the outer wall of side core 15 is vertically fixed with limiting plate 17, limiting plate 17 is arranged between bearing pin 16 and moving platen 7, the sidewall of moving platen 7 is provided with banking pin 14, banking pin 14 one end is arranged in moving platen 7, it is outside that the other end is arranged on moving platen 7, limiting plate 17 is arranged between the termination of moving platen 7 and banking pin 14 away from one end of side core 15.In the technical program, utilize the pressing of mould, blank 2 is pressed between cover half seat 1 and punch 4, and side core 15 is laid down from the stress of sidewall by blank 2, make blank 2 shaping, shaping rear blank and mould inner wall have certain cohesive, if adopt the mode of manual removal, just easily cause the damage of blank outer wall, during this time, the first rotating pin 16 of operating personnel, limiting plate 17 is rotated an angle between bearing pin 16 and moving platen 7, disengaging and the contact between bearing pin 16 and moving platen 7, such side core 15 just can be extracted out, side core 15 can not stop the movement of blank 2, then downward pressure is applied to side core 15, cover half seat 1 and moving platen 7 are disengaged, this process cover half seat 1 keeps motionless, moving platen 7 moves down, spring 10 is squeezed, push rod 9 is not mobile, elasticity makes push rod 9 be ejected from punch 4 by blank 2, this process time is very short, blank 2 fast and punch 4 depart from, the outer wall of blank can not be damaged, ensure that blank Forming Quality, solve after blank is bonded in mould inside in existing mold production and take out the problem easily causing damage in blank process.
The bottom indent of described punch 4 forms groove 28, support plate 13 is provided with groove, groove is communicated with groove 28, the top indent of base 12 forms groove 3 11, groove 3 11 is communicated with groove, and the center line of the center line of groove 28, the center line of groove and groove 3 11 overlaps, push rod 9 is simultaneously through groove 28, groove and groove 3 11, and the two ends of spring 10 contact with the bottom of groove 3 11 with the top of groove 28 respectively.Push rod 9 forms multistage, form different diameter segment, section diameter in groove one is minimum, major diameter is formed in the part near base 12, and this diameter value is greater than the port sizes of groove, the stroke of push rod 9 movement can be limited like this rational scope, the i.e. degree of depth of groove 3 11, avoid causing that push rod 9 displacement is too large to be damaged mould, the too little problem causing again push rod 9 blank cannot be ejected of displacement, rational scope can make blank 2 just be ejected.
