Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Depend on Figure 1 to Figure 8 The structure diagram of the core-pulling device of the flange mold of the present invention shown in the present invention can be seen, including the upper mold assembly, the lower mold assembly and the ejection mechanism, and the mold cavity of the flange is formed after the two molds are closed, and the ejection mechanism is connected to the lower mold assembly. In the mold assembly; the ejection mechanism is a secondary ejection mechanism, wherein the first-stage ejection is used to form the outer surface of the inclined flange hose joint 1-2, and is used to form an inclined flange. The core-pulling mechanism of the inner diameter of the hose joint 1-2, the second-stage ejector is used for the overall ejection of the finished flange, and the first-stage ejector mechanism and the second-stage ...

Abstract

The invention discloses a core pulling device of a flange mold. An ejection mechanism is a secondary ejection mechanism, according to a first-stage ejection mechanism, a shape demolding mechanism used for the outer surface of an inclined hose joint (1-2) on a flange and a core pulling mechanism used for an inner core of the inclined hose joint (1-2) are included, the secondary ejecting mechanism is used for whole ejecting of a flange finished product, and the first-stage ejecting mechanism and the second-stage ejecting mechanism are connected through a stroke control assembly; the stroke control assembly comprises a guide connecting plate (2) and a stroke drive plate (3), the lower end of the guide connecting plate (2) is fixedly connected to the side wall of a lower die fixed plate (5) in a lower die assembly, the lower end of the stroke drive plate (3) is fixedly connected with an ejector pin plate (6) in the ejecting mechanism, and the upper end of the stroke drive plate (3) is fixedly connected or in sliding connection with a lower die movable plate (4) in a lower die assembly. By the adoption of the above structure, the action is stable and reliable, it can be ensured that the inclined hose joint can be subject to demolding smoothly, other demolding operations are not affected, and therefore the flange product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a core-pulling device for flange molds. Background technique [0002] A flange is a flanged part, which is used in all walks of life, and in auto parts, it also usually has a flange. In order to reduce the space occupied by parts and cooperate with other functions, the flanges in auto parts are usually special-shaped flanges. as attached figure 1 As shown in , the flange includes a flange body 1, one end of the flange body 1 is provided with a straight pipe joint 1-1, and the opposite end is provided with an inclined hose joint 1-2, and the straight pipe joint 1- 1 is communicated with the inclined hose connector 1-2. [0003] Therefore, because the structure of this oblique hose joint is inconsistent with the normal vertical mold opening direction, the demoulding structure of the hose joint in the flange mold is very complicated, difficult to demould, and even Product damage o...
