Embodiment

[0020] Such as figure 2 As shown, a hot nozzle core structure dedicated to black materials, including a nozzle core 1, a flow channel 2 that communicates with the nozzle body flow channel, and the end of the nozzle core 1 is used for the gate for the color material to flow out 3; The gate 3 is provided with a grid 4 laterally. The "horizontal" refers to the direction along the cross-section of the gate, relative to the "longitudinal" formed by the direction in which the gate communicates with the runner.

[0021] The grid 4 is a knife-edge grid. The grid 4 is a frame made of a group of parallel grid bars, or a single grid bar. When the grid is a frame made of a group of parallel grid strips, the frame-type grid divides the gate 3 into several splitters. When the grid is a grid bar, the grid bar divides the gate 3 into two shunt ports.

[0022] Since the present invention adds a knife-edge grid at the gate, the knife-edge grid can be a frame made of a group of parallel gri...

Abstract

The invention discloses a hot nozzle core structure special for a black material. The hot nozzle core structure comprises a nozzle core, a flow channel through which the nozzle core is communicated with a flow channel of a hot nozzle body, and a pouring gate which is formed at the end of the nozzle core and is used for a color material to flow out, wherein a grid is arranged at the pouring gate transversely. By using the scheme, the problem that the phenomena of drawing and drooling are caused easily when the color material is extruded by using the conventional hot nozzle core special for the black material is mainly solved; and the product yield is improved.

Description

technical field [0001] The invention relates to a hot runner hot nozzle, in particular to a hot nozzle core structure of a hot runner system, especially a special hot nozzle core structure for black materials. Background technique [0002] At present, the injection mold commonly used in the injection molding industry is a hot runner injection mold, which generally includes a hot nozzle body, a flow channel inside the hot nozzle body, a nozzle core connected to the flow channel at the front end of the hot nozzle body, and a nozzle core located on the outer periphery of the hot nozzle body. The heating device is installed on the body of the hot nozzle to keep the injection plastic part in a molten state, flow through the flow channel and extrude from the nozzle body for injection molding. [0003] At present, different nozzle core structures are often used for different color materials, such as figure 1 As shown, it is a hot nozzle core structure dedicated to black materials,...
