After the mold opening is completed, it enters the ejection state; the locking block 12 is clamped in the slot 131 of the lower buckle machine 13, thereby locking the ejector panel 7 and the ejector bottom plate 8, and the oil cylinder drives the ejector panel 7 and the ejector bottom plate 8 to move upward, The ejector pin 10 on the ejector pin panel 7 drives the injection molded part 9 to eject upward, and the ejector pin 11 on the ejector pin bottom plate 8 drives the straight top block 2 to eject upward. When moving upward, the first oblique core-pulling 3 slides on the mounting seat 19 and gradually leaves the glue position, the second oblique core-pulling 4 is separated from the hook 221 , and the second oblique core-pulling 4 is opposite to each other under the force of the first elastic element 6 . The straight top block 2 moves downward to gradually leave the glue position and complete the first ejection. The second sloping surface 141 on the upper locking machine 14 presses the first sloping surface 121 on the locking block 12 to separate the ejector panel 7 from the ejector bottom plate 8, and the oil cylinder 23 drives the ejector panel 7 to continue to move upward, so that the ejector 10 will inject Piece 9 is ejected, the second ejection is completed, and the demoulding is completed.

本实施例提供的一种扰流板支架模具二次顶出抽芯结构,在后模上安装有抽芯机构,通过设置直顶块、第一斜抽芯和第二斜抽芯,第一斜抽芯、第二斜抽芯与直顶块配合,能够有效保证产品的成型质量,便于脱模;顶针底板和顶针面板上安装有联动机构,直顶块与顶针底板配合,能够实现二次脱模,使脱模更简便,克服了现有脱模结构不适用结构复杂的产品、脱模困难、脱模质量差的缺陷。This embodiment provides a core-pulling structure for secondary ejection of a spoiler bracket mold. A core-pulling mechanism is installed on the rear mold. By arranging a straight top block, a first oblique core-pulling and a second oblique The oblique core-pulling, the second oblique core-pulling and the straight top block can effectively ensure the molding quality of the product and facilitate demoulding; a linkage mechanism is installed on the thimble bottom plate and the thimble panel, and the straight top block cooperates with the thimble bottom plate to realize secondary Demoulding makes demolding easier and overcomes the defects that the existing demolding structure is not suitable for products with complex structure, difficult demoulding and poor demoulding quality.
