Problems solved by technology

[0002] In the existing mold, when the driving mechanism directly pulls the core to move the position, the parts that match the position cannot be locked by the mold clamping force, and it is necessary to apply an external force to the matching parts through the driving mechanism. However, due to the inaccuracy of the driving mechanism, it is often As a result, the row position retreats under the action of injection molding pressure, resulting in defects such as excess glue, burrs, and flashes on the product, resulting in poor dimensional accuracy of the product, affecting the production progress, and reducing the quality of the product

Abstract

The invention discloses a self-locking mechanism capable of preventing slide retreating and a self-locking and unlocking method of the self-locking mechanism. The self-locking mechanism capable of preventing slide retreating comprises a slide push plate, fixed plates, a limiting mechanism, an ejection block and a driving mechanism, the fixed plates are arranged on the two sides of the slide push plate, the tail end of the slide push plate is provided with a self-locking groove, the limiting mechanism is located inside the self-locking groove, the ejection block is located in a groove opening of the self-locking groove, the top of the ejection block is provided with an inclined top face and a limiting face, the limiting face is located below the inclined top face, the driving mechanism is connected with the ejection block and drives the ejection block to move, self-locking of the limiting mechanism can be achieved, the position of the slide push plate can be locked effectively, slide push plate retreating caused by too large injection molding pressure is prevented, the defects of too much glue, flashing, trimming and the like are prevented, and the quality of an injection molding product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a self-locking mechanism for preventing a row from retreating and a self-locking and unlocking method thereof. Background technique [0002] In the existing mold, when the driving mechanism directly pulls the core to move the position, the parts that match the position cannot be locked by the mold clamping force, and it is necessary to apply an external force to the matching parts through the driving mechanism. However, due to the inaccuracy of the driving mechanism, it is often As a result, the line position retreats under the action of injection molding pressure, resulting in defects such as excess glue, burrs, and flashes on the product, resulting in poor dimensional accuracy of the product, affecting production progress, and reducing product quality. Contents of the invention [0003] The object of the present invention is to provide a self-locking mechanism for pre...
