Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding technology, and in particular to a slanted injection hot nozzle. Background Technology
[0002] Hot nozzles are extensions of the injection molding machine barrel, primarily controlling the temperature of the manifold and hot nozzles to ensure that the plastic in the runner and gate remains molten through heating. They are mainly divided into open hot nozzles and needle valve hot nozzles.
[0003] In common injection molding machines, the hot nozzle is installed at one end of the barrel. The hot nozzle is usually set vertically. When injection molding products with an inclined surface, the inclined surface of the product will disrupt the opening of the hot nozzle, making it impossible to select the optimal injection point, reducing the production quality of the product. In addition, sprue will be left at the connection between the hot nozzle and the product, which requires secondary processing to remove the sprue, reducing production efficiency.
