Description
技术领域Technical Field
本实用新型涉及一种汽车保险杠模具格栅位内分型交叉斜顶脱模机构，属于注塑模具领域。The utility model relates to an in-position parting cross-sloping top demoulding mechanism for a grille of an automobile bumper mould, and belongs to the field of injection moulds.
背景技术Background Art
采用注塑模具生产塑料产品，例如汽车保险杠等，根据产品形状和结构分析，以及整车厂的外观要求，现有的汽车保险杠模具大多采用内分型结构，即其最外轮廓线的两端（轮眉处）分型线在产品的背面，使其外表面无分型线，外型美观。但随着人们对汽车外型的要求越来越高，目前有些整车厂家要求保险杠的格栅装配位也要采用内分型脱模结构，即要求格栅位的分型线位于装配倒扣的下面，致使装配倒扣无法直接脱出，因此，在设计加工模具时，在保险杠的格栅装配位还需设计一种内分型脱模结构。Injection molds are used to produce plastic products, such as car bumpers, etc. According to the product shape and structure analysis, as well as the appearance requirements of the vehicle manufacturer, most of the existing car bumper molds use an internal parting structure, that is, the parting lines at both ends of its outermost contour line (at the wheel eyebrow) are on the back of the product, so that there is no parting line on the outer surface, and the appearance is beautiful. However, as people's requirements for the appearance of cars are getting higher and higher, some vehicle manufacturers currently require that the grille assembly position of the bumper also adopt an internal parting demoulding structure, that is, the parting line of the grille position is required to be located below the assembly undercut, so that the assembly undercut cannot be directly removed. Therefore, when designing and processing molds, an internal parting demoulding structure is also required at the grille assembly position of the bumper.
