Abstract

The invention relates to a water needle device for water-assisted injection molding, and relates to a water-assisted injection molding device, in particular to a water needle device for water-assisted injection molding. The present invention includes a water needle body, a crown water needle cap (1D) is arranged at the water outlet of the water needle body, the water needle cap (1D) completely covers the water outlet, and the water needle cap (1D) is detachably and movablely connected with the water needle body, so that The water needle cap (1D) can be detached under the push of water from the water needle body. The beneficial effect of the present invention is that a water-assisted injection molding water needle device is provided, which can effectively solve the problem of polymer polymer melt clogging the water needle.

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 ...
