(2) injecting plastisol into the mould cavity from the injection hole;
(3) continuously applying pressure to the mold cavity to compact the melt and increase the density of the plastic to compensate for the shrinkage behavior of the plastic;
(4) stopping applying pressure, and waiting for cooling water in the cooling water path to circulate to cool the die, so that the product is solidified and cooled to room temperature;
(5) and opening a valve of the second air port to separate the inclined slide block connected with the piston rod of the air cylinder from the mold, and opening the female mold and the male mold to take out the product.
As a further improvement, the first air port is arranged on a pipeline connected with a rod cavity of the air cylinder.
