Mold for producing centrifugal fan blade

Abstract

The invention relates to a mold for producing a centrifugal fan blade. The mold comprises a movable mold which is fixed in an injection molding machine and moves along with an internal mechanism of the injection molding machine and a fixed mold which is fixed in the injection molding machine; the movable mold and the fixed mold are buckled to each other; a first mold core is arranged at one end, close to the fixed mold, of the movable mold; a second mold core aligned to the first mold core is arranged at the end, close to the movable mold, of the fixed mold; fan blade forming grooves for forming fan blades are evenly formed in the circumferential side ends of the first mold core and the second mold core in the circumferential direction; and forming sliding blocks wrapping the first mold core and the second mold core are slidably arranged on the portions, on the two sides of the first mold core, of the movable mold; a forming cavity is formed among the two forming sliding blocks, the first mold core and the second mold core; a main plate forming groove for forming a fan blade main plate is formed between the first mold core and the second mold core; the main plate forming groove is communicated with the fan blade forming grooves; and a feeding channel communicated with the main plate forming groove is formed in the middle of the second mold core. With the mold adopted, the quality of the centrifugal fan blade can be improved.

Description

technical field [0001] The present application relates to the technical field of injection molds, in particular to a mold for producing centrifugal fan blades. Background technique [0002] At present, injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] Existing a centrifugal blade, such as Figure 7 As shown, it includes the main board of the fan blade in the shape of a disk in the middle, the fan blades integrally formed on both ends of the main board of the fan blade, and the stability ring integrally formed on the end of the blade away from the main board of the...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned related technical solutions have the following defects: the overall structure of the above-mentioned centrifugal fan blade is long, and when the conventional injection mold is fed from one end to produce the centrifugal fan blade, it may cause the blades at both ends of the fan blade main board to be formed and condensed. The time is different and the strength is different. When using the centrifugal fan blade, it may cause the fan blade on one side to be more easily damaged
