Secondary ejection mechanism for speaker mesh of door panel

Abstract

The invention discloses a secondary ejection mechanism for a speaker mesh of a door panel. The secondary ejection mechanism comprises a speaker mesh ejector pin panel and a speaker mesh ejector pin bottom plate, which are fixed together through screws, wherein a plurality of ejector pins are fixedly arranged on the speaker mesh ejector pin panel, and a speaker mesh base plate is fixedly arranged on a die core plate to be prevented from falling; a nitrogen spring is arranged on the speaker mesh ejector pin bottom plate and the speaker mesh ejector pin base plate; in addition, ejection limiting blocks are arranged on the surface of the speaker mesh ejector pin panel. The secondary ejection mechanism is powered by the nitrogen spring, and when a product is ejected, the speaker mesh is ejected by the speaker mesh ejector pin panel and the speaker mesh ejector pin bottom plate under the action of the nitrogen spring. After ejection is stopped, the product is continuously ejected along with movement of the ejector pin to finish secondary ejection operation of the whole product. According to the mechanism adopting such a structure, an ejection distance of the speaker mesh is well controlled by utilizing an ejection process of a die, and the mechanism is a feasible mechanism of which the ejection process is stable and safe.

Description

technical field [0001] The invention belongs to the field of injection molds, in particular to a secondary ejection mechanism for the horn mesh of a door panel. Background technique [0002] In the process of plastic mold design, especially the front and rear door panels of automobiles, it is often seen that there are speaker mesh designs on the door panels. Because the speaker mesh is small, the required thimble is also small. In this case, a longer thimble is required, which will inevitably cause the thimble to be affected by bending deformation. Therefore, it is necessary to find a kind of ejection mechanism that can not only satisfy the demoulding of the horn mesh, but also make the strength of the thimble pin unaffected. Contents of the invention [0003] In view of the above technical difficulties, the purpose of the present invention is to provide a secondary ejection mechanism that can satisfy the ejection of the horn mesh without affecting the strength of the eje...
