s4, controlling the hydraulic telescopic rod to extend through the hydraulic pump, so that the first mold is tightly connected with the second mold;
s5, feeding by a feeding pump;
s6, pushing the push block by the push rod to push the molten plastic to the mold cavity;
s7, after cooling, contracting the hydraulic telescopic rod, and then taking out the product;
and S8, performing finish machining, polishing and drilling on the product.
10. The process for machining the special-shaped shell according to claim 9, wherein the process comprises the following steps:
communicating the plastic in the molten state to a molten plastic bin;
mutually sliding and connecting a T-shaped sliding block of a first mold and a T-shaped sliding groove of a middle plate to enable the first mold to be placed in the middle of the middle plate, mutually sliding and connecting a T-shaped sliding block of a second mold and the T-shaped sliding groove to enable the second mold to be placed in the middle of a tail plate, and enabling the heights of the first mold and the second mold to be corresponding;
bending the hose to enable the release agent in the release agent storage box to be sprayed to the surfaces of the die cavities of the first die and the second die through the hose, so that the molten plastic in the die cavity is not adhered to the inner surface of the die cavity when the molten plastic is solidified;
the hydraulic telescopic rod is controlled by the hydraulic pump to extend, so that the middle plate is close to the tail plate, the sliding foot moves on the sliding sheet to reduce friction force, and when the first die is tightly connected with the second die, the hydraulic telescopic rod stops extending;
the feeding pump works to discharge the plastic in the molten plastic bin from the feeding pipe and enter the communicating cavity through the opening;
the push block is controlled by the push rod to move along the communicating cavity to the die cavity, so that the molten plastic in the communicating cavity moves to the die cavity, and finally the die cavity is filled;
after the product is cooled, the hydraulic telescopic rod contracts, and then the product is taken out;
carry out the finish machining with the product, make its precision more accurate, then polish for the product surface is smooth, drills on the surface at last for satisfy the demand.
