Abstract

The invention provides a water jet device for water injection moulding, and relates to a water injection moulding device, in particular to the water jet device for water injection moulding. The water jet device comprises a water jet body, a crown-shaped water jet cap (1D) is arranged at a water outlet of the water jet body, the water jet cap (1D) completely covers the water outlet, and the water jet cap (1D) is detachably connected with the water jet body, so that the water jet cap (1D) can be detached by water outlet pushing of the water jet body. The water jet device has the beneficial effects that the water jet device for water injection moulding is provided, and the problem that a water jet is blocked by a polymer macromolecule molten mass can be effectively solved.

Description

technical field [0001] The invention relates to a water-assisted injection molding process and a device, in particular to a water needle device for water-assisted injection molding. technical background [0002] Water-assisted injection molding technology is a new technology compared with the more mature gas-assisted injection molding technology. Compared with gas-assisted injection molding technology, it has the advantages of short cooling time and molding cycle, good product quality, low production cost and high production efficiency. The molding process of water-assisted injection molding technology is: inject polymer polymer melt into the mold cavity; inject high-pressure water into the polymer polymer melt through the water needle device, and push the unsolidified polymer polymer melt inside to completely Fill the mold cavity, or push the unsolidified polymer polymer melt out of the mold cavity; open the mold, and take out the hollow product. However, one of the keys ...
