Chain mold injection molding technology of polystyrene plastic granules

Abstract

The invention discloses a chain mold injection molding technology of polystyrene plastic granules. The chain mold injection molding technology comprises the following steps of enabling plastics in a melting state to flow to granule holes which communicate with a feeding hole, and besides, enabling the plastics in the melting state in the granule holes which communicate with a discharge hole to fall to the feeding end of a water-cooling forming device; while the plastics in the melting state fall down to forming holes in the feeding end of a chain mold piece, enabling the plastic granules in the forming holes in the discharge end of the chain mold to fall down to a water separation output device, and at the same time, enabling cooling water to flow to the water separation output device through a material draining nozzle; enabling an intermittent motion mechanism to run a cycle, wherein a mold body/a mold shaft can firstly rotate, and the rotating displacement is equal to the displacement between every two adjacent groups of granule holes; a chain mold body moves, and the movement displacement is equal to the distance between every two adjacent groups of the forming holes; then enabling the mold body/ the mold shaft to be still and repeating the step I in a reciprocating manner; and separating the polystyrene plastic granules from water, performing surface air drying treatment, and storing the polystyrene plastic in the granule storing mechanism.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a plastic granulation method. Background technique [0002] With the continuous development of science and technology, the application of plastic products has become more and more extensive, and the plastic pollution caused by it has also become more serious. At present, my country's treatment of waste plastics is generally to make them into granules and store them, waiting for the follow-up Utilization, the existing plastic granulator generally extrudes strip-shaped plastics through an extrusion molding mechanism, and then cuts the strip-shaped plastics to obtain plastic granules, but most of the plastic granules obtained by this method have different shapes. Fixed, the specifications are not uniform, which is not conducive to subsequent sales and finishing treatment. For this reason, it is necessary for the present invention to propose a plastic granulation equipment that adopts...
