Brief description of the drawings
Fig. 1 is the structural representation of a kind of stripper apparatus that the utility model proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of stripper apparatus that the utility model proposes.
With reference to Fig. 1, a kind of stripper apparatus the utility model proposes, for taking off the elastic component 7 being made by elastomeric material in mould 3 die cavitys 4, die cavity 4 runs through middle mould 3 up and down, die cavity 4 is column structure, comprise supporting seat 2, be arranged on the pneumatic means 1 on supporting seat 2, be arranged on the stripper plate 5 on supporting seat 2, the removably connect power transmission shaft of pneumatic means 1 of middle mould 3, during pneumatic means 1 drives, mould 3 moves or away from stripper plate 5 to stripper plate 5, particularly, between middle mould 3 and the power transmission shaft of pneumatic means 1, with bolts or alignment pin is connected, middle mould 3 is constantly used, formation streamline is produced, improve operating efficiency.
Stripper plate 5 tops are provided with many push rods 6, make push rod 6 one by one correspondence enter in die cavity 4 and push elastic component 7, make elastic component by the middle mould 3 top demouldings.
The height of push rod 6 is greater than the degree of depth of die cavity 4, the cross-sectional area of push rod 6 is less than the cross-sectional area of die cavity 4, particularly, arbitrary push rod 6 axis and corresponding die cavity 4 deads in line, make push rod 6 clamp-on the process of die cavity 4 more smooth, further, the described lower beam cross section area of push rod 6 is 5-7:8-10 with through hole 7 cross-sectional areas ratios, under this ratio, when push rod 6 is clamp-oned die cavity 4 and can not clamped elastic component 7 lower end, the cross section that has increased push rod 6, has strengthened the power of clamp-oning, and elastic component 7 is ejected more rapidly.
The vertical parallel distribution of push rod 6, push rod 6 comprises the lower beam portion of fixing stripper plate 5 and the upper pole part upwards being extended to form by lower beam portion upper end, described upper pole part and described lower beam portion seamlessly transit, described lower beam portion is column structure, in direction straight up, described upper pole part cross-sectional area reduces gradually, the curved portion of the outline line of the longitudinal section of described upper pole part is one section of class Bezier, at the place, longitudinal section of described upper pole part, plane is set up plane right-angle coordinate, and described curve equation is B (t)=(1-t)
