Abstract
The invention discloses a novel pouring mold. The novel pouring mold comprises a main filling nozzle head and a main runner located inside the main filling nozzle head, wherein the diameter of the upper portion of the main runner is smaller than that of the lower portion of the main runner. When a nozzle head part of an injection molding machine injects materials into the main filling nozzle head, the phenomenon of material overflowing of the nozzle head part of the injection molding machine is effectively avoided, and waste of raw materials is avoided.
Description
Technical field
The present invention relates to the injection mold field, relate in particular to a kind of Novel injection mold.
Background technology
The hot flow path of conventional injection mold is designed to through type, but this project organization easily the flash phenomenon occurs at the nozzle of injector head in process of production, causes the waste of raw material.
Summary of the invention
In order to overcome defects, the invention provides a kind of Novel injection mold, it is simple and practical, can avoid the flash phenomenon of injector mouth section.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of Novel injection mold, comprise that main filling mouth mouth and location be located at the sprue in described main filling mouth mouth, and the upper diameter of described sprue is less than its underpart diameter.
As a further improvement on the present invention, described sprue is provided with top, bottom and the arc-shaped transition section between the upper and lower part, and the vertical section of the upper and lower of described sprue all is straight tube shape.
The invention has the beneficial effects as follows: be designed to upper diameter less than the shape of lower diameter by the sprue of the location being located in main filling mouth mouth, when injector mouth section in the main filling mouth mouth during material feeding, can effectively avoid the flash phenomenon of injector mouth section, avoid the waste of raw material.
Description of drawings
Fig. 1 is structural representation of the present invention.
