The clamping device is one of the main components of the
vertical injection molding machine. Vertical injection molding machine
toggle clamping mechanism is many a design variable, sport extremely
complex institutions. FIG method used in the past to try to scrape
together the design, calculation is extremely voluminous, spend a lot of
design time, although the designer tried to select a good program from a
number of possible designs, but this design method lacks a quantitative
expression of the design goals, design parameters it is impossible to
obtain through rigorous and accurate optimization.
Can only be determined by analogy, the result is still far from
satisfying, showing that there is room for improvement design. So, with
the optimized design methods toggle mechanism is an inevitable trend, it
can satisfy people more complex mechanical design of the proposed, more
precise requirements.
The establishment of a mathematical model
Design of different types of vertical injection molding machine
toggle mechanism, the objective function of different nature. Design of
large and medium-sized machines, the objective function and generally
minimal axial dimension, because not only can reduce the size of the
machine, and in the processing of products, low energy consumption, but
also saves time.
Selection and optimization method Box 2
Select the optimization method is a very important issue.
Without complex method requires derivative, they do one-dimensional
search methods, the nature of the objective function and constraint
functions no special requirements, is a direct solution method. And the
program is simple, fast convergence, good effect, which is only
nine-dimensional design issues is very effective.
3 conclusions
Vertical injection molding machine in the actual design work,
trial and error method used in FIG design, designers spend a lot of
time, not exactly. And by optimizing design method, satisfactory
results, and the entire block common good. Adopting varus up-down toggle
clamping mechanism, can use the program, so that you spend a lot of
time to solve a design problem can not be solved.
