industry is inseparable from the assurance of tire quality. As an
When the automatic mold adjustment up or automatic important equipment for tire production, the curing press has
mold adjustment down signal is triggered, the corresponding gradually evolved towards more intelligent, green, and safe
mechanical mold adjustment control function block is directions through continuous development, improvement, and
executed. Figure 9 shows the mechanical mold adjustment innovation. This article provides an intelligent transformation
control program. According to the corresponding triggered plan for the curing press, which has the advantages of
up or down signal, the PLC outputs the mold adjustment up being economical and easy to implement. In particular, this
or mold adjustment down signal to control the forward and transformation plan can achieve the function of one-time data
reverse rotation of the mold adjustment motor, achieving the fitting and multiple automatic mold adjustments, reducing
mold lifting and lowering action. Through the above rigorous the intensity of worker mold adjustments and having positive
electrical control design process, the one-button automatic significance for the intelligent transformation of the curing
mold adjustment function of the mechanical tire shaping and press.
curing press mold adjustment device is realized, improving the
