Technical field
The utility model relates to a kind of modification injection mold, belongs to technical field of mold.
Background technology
At present, generally utilize mould to produce in manufacturing enterprise, its operating efficiency is high, easy to operate.The molding cycle of thermoplastic injection molding is short, production efficiency is high, and injected plastics material is little to the wearing and tearing of mould, in large quantity complicated, the picture on surface of forming shape and mark is clear, dimensional accuracy is high plastic.
But existing injection mold does not generally have modified function, after modification, same injected plastics material can possess different performances according to demand, as possessed the performances such as antibiotic property, hydrophobicity after modification; Or the method by modification improves plastic quality, as aspects such as density, hardness, precision, outward appearance, processability, the transparency, mechanical performance, electromagnetic performance, chemical property, decay resistance, resistance to ag(e)ing, wearability, hot property, anti-flammability, barrier and cost-effectivenes, and modifying plastics is to reduce costs, improve the effective method of performance.
The moment that the produced simultaneously cation of plasma generator and anion carry out positive and negative charge neutralization in air produces huge energy release, thereby cause its change of bacterial structure or conversion of energy around, thereby cause bacterium dead, realize the effect of its sterilization.Because the quantity of anion is greater than the quantity of cation, therefore unnecessary anion still exists, and can reach smoke elimination, dedusting, elimination peculiar smell, improve the quality of air, with the health-care effect promoting health.
Also have, present injection mold is because feed pipe is a penetrating pipeline, injected plastics material is directly flowed out by pipeline, the injected plastics material diameter flowing out is excessive, thickness is blocked up, and viscosity is too sticky, therefore be unfavorable for that modified gas is by its even modification, the surface that often occurs injected plastics material fluid is modified, but the middle phenomenon not being modified.
