Problems solved by technology
During the demoulding process, the slider of the mold is more likely to stick to the buckle, which will lead to the buckle being more likely to be pulled apart during the disengagement process of the slider and the product, resulting in a lower yield of plastic products. Visible, the reliability of the injection mold in the prior art is lower

The invention discloses a tripping structure and an injection mold, and belongs to the technical field of injection molding.The tripping structure comprises a sliding block assembly, an inclined guide column and an ejection assembly, and the sliding block assembly is provided with a first through hole; the inclined guide column is inserted into the first through hole in a sliding mode, the extending direction of the inclined guide column intersects with the first direction, and the inclined guide column moves in the first direction and can drive the sliding block assembly to move in the second direction; the ejection assembly comprises a base and an ejection piece connected to the base, when the inclined guide column drives the sliding block assembly to move by a first preset distance in the second direction to be released, the base and the ejection piece can eject a product in the second direction, and when the inclined guide column drives the sliding block assembly to move by the distance larger than the first preset distance in the second direction, the ejection piece can eject the product out. The sliding block assembly drives the base and the ejection piece to be separated from the product in the second direction. According to the tripping structure and the injection mold provided by the invention, the condition that a product is adhered to the tripping structure is reduced, the yield of the product is improved, and the reliability is relatively high.
Description
technical field [0001] The invention relates to the technical field of injection molding, in particular to a tripping structure and an injection mold. Background technique [0002] Injection molds are widely used in the processing of plastic products, and have the advantages of high processing efficiency and high precision of finished products. [0003] Figure 18 It is a product obtained by injection molding in the prior art, wherein, such as Figure 18 As shown, there are multiple buckle positions on the product, and the multiple buckle positions specifically include a first hole position 1001 , a cantilever position 1002 and a second hole position 1003 . During the demoulding process, the slider of the mold is more likely to stick to the buckle, which will lead to the buckle being more likely to be pulled apart during the disengagement process of the slider and the product, resulting in a lower yield of plastic products. It can be seen that the reliability of the injecti...
