An injection mold for a motor wind wheel

Abstract

The invention discloses an injection mold of a motor wind wheel. The injection mold comprises a movable mold body, a fixed mold body and slider mechanisms, wherein each slider mechanism is provided with a small slider, a wedge and an inclined guiding column and further provided with a large slider. A sliding channel is arranged in each large slider. Each wedge is placed in the corresponding sliding channel. Each large slider is provided with a through hole for the corresponding inclined guiding column to penetrate. A large rotary table rotating around the movable mold body is arranged below the fixed mold body and provided with a plurality of strip-shaped arc grooves extending from interior to exterior. The strip-shaped arc grooves are correspondingly formed in the positions below the large sliders in a one-to-one manner. Each large slider is fixedly provided with a connecting rod pin stretching into the corresponding strip-shaped arc groove. A rotation driving device driving the above large rotary table to rotate is arranged outside the fixed mold body. Compared with the prior art, one part of the overall demolding power source of the slider mechanisms of the injection mold is finished through the inclined guiding columns, the other part of the overall demolding power source of the slider mechanisms of the injection mold is finished through cooperation of the large rotary table and the large sliders, the inclined guiding columns do not serve as the power source for overall demolding of the slider mechanisms, the length of the inclined guiding columns is greatly reduced, the overall strength of the inclined guiding columns is high, and fracture due to stress is not likely to happen.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for injection molding of a motor wind wheel. Background technique [0002] Existing motor wind rotors, such as figure 1 , 2 As shown, its structure generally includes an upper ring body 100, a lower ring body 200, and an arc-shaped plate 300 between the upper and lower ring bodies. There are several arc-shaped plates 300, and each arc-shaped plate 300 is arranged around at intervals. A cavity 400 is formed between the two arc-shaped plates 300 , and the inner end of the arc-shaped plates 300 extends upwards with an undercut 301 located on the inner wall of the upper ring body 100 and integrally formed with the upper ring body 100 . Due to the existence of the undercut 301, the release direction of the injection mold is inconsistent with the mold opening direction of the injection mold when the motor fan wheel is formed. Lateral parting and lateral core pulling are required...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an injection mold for the motor wind wheel to solve the problem that the movement of the small row and the wedge is controlled by the oblique guide post in the prior art, resulting in a long overall length of the oblique guide post and low strength of the oblique guide post , easy to break, unable to guarantee the release of the positioning mechanism
