Embodiment Construction

[0017] Such as figure 1 , 2 As shown, a secondary ejection mechanism for an injection mold for an automobile door panel includes a mold seat plate 7 that is equipped with a movable mold 1 through mold feet 18, and one of the mold seat plate 7 and the movable mold 1 There is a secondary ejection mechanism between.

[0018] The secondary ejection mechanism includes a thimble plate 5 and a thimble web 6 installed between the mold seat plate 7 and the movable mold 1. The thimble plate 5 and the thimble web 6 are driven up and down by a cylinder 17 Movement, the above-mentioned cylinder 17 is installed on the side wall of the movable mold 1.

[0019] The ejector pin 13 is fixed on the ejector plate 5, and the ejector pin 13 is used to eject the part of the automobile door panel except the mesh. A mesh tie rod 9 is fixed on the thimble plate 5 and the thimble web 6, the movable mold 1 is formed with a pit, and a mesh thimble plate 4 is installed in the pit, and the mesh thimble plate 4...

Abstract

The invention relates to a secondary ejecting mechanism of an automobile door panel injection mold. The secondary ejecting mechanism of the automobile door panel injection mold comprises a mold seat board, wherein the mold seat board is provided with a movable mold through a mold leg, an ejector pin board and an ejector pin ventral board which are driven to do vertical motion by an oil cylinder are arranged between the mold seat board and the movable mold, the ejector pin board is fixedly provided with a top rod, mesh pull rods are fixedly arranged on the ejector pin board and the ejector pin ventral board, the movable mold is provided with a concave pit, the concave pit is internally provided with a mesh ejector pin board, the mesh ejector pin board is fixedly provided with a mesh ejector pin which is used for ejecting a mesh opening of an automobile door panel, a mesh ejecting spring which is used for supplying power for ejecting the mesh ejector pin board is arranged in the pit, the upper ends of the mesh pull rods are fixedly arranged on the mesh ejector pin board, the lower ends of the mesh pull rods are provided with rod caps in bulged ring shapes, the ejector pin ventral board is provided with a guide hole which is in size match with the rod cap, and the rod cap is positioned in the guide hole and can slide vertically. The secondary ejecting mechanism of the automobile door panel injection mold, disclosed by the invention, has the advantage that the breaking (bending) probability of the ejector pin is reduced to a large extent.

Description

technical field [0001] The invention relates to a secondary ejection mechanism of an injection mold for an automobile door panel, belonging to the technical field of moulds. Background technique [0002] Automobile door panels with mesh are currently widely used, but their manufacturing process is extremely troublesome. Because the distance between the mesh holes is very small, it is impossible to use directly large thimbles for ejection, and only thimbles with a diameter of 1.5mm or 2mm can be used. Due to the large ejection distance, these small thimbles are very prone to broken (bent) thimbles. Phenomenon. For this problem, the present inventor once designed a kind of mesh ejection mechanism, and the thimble of this ejection mechanism is made into the stepped structure that is made of two small thimbles with different thicknesses. After testing, the stepped structure reduces the probability of the thimble breaking (bending) to a certain extent, but the breaking (bending...
