Abstract

The invention discloses a mold ejection device for products with multiple ribs inside. The mold ejection device comprises straight ejecting mechanisms, oblique ejecting mechanisms, a top plate assembly and at least one set of secondary ejection mechanism; multiple sets of straight ejecting mechanisms are arranged, the lower ends of the straight ejecting mechanisms are connected to the top plate assembly, and the upper end edges of the straight ejecting mechanisms abut against the bottom end of a product (1); the number of the oblique ejecting mechanisms is determined according to the number of through holes (2) in inner rib plates (3) inside the product (1), the lower ends of the oblique ejecting mechanisms are connected to the top plate assembly, and the upper ends of the oblique ejecting mechanisms abut against the inner bottom surface of the product (1); and the secondary ejection mechanisms are rotatably connected to the top plate assembly, and one end of the secondary ejection mechanism is movably connected with the bottom of one set of straight ejection mechanism. After adoption of the structure, during complete demoulding, the stroke of straight ejecting rods is larger than the stroke of oblique ejecting rods, and therefore, an operator can very conveniently take down the product from the straight ejecting rods without damaging the product.

Description

technical field

[0001] The invention relates to the technical field of moulds, in particular to a mold ejection device for internal multi-rib products. Background technique

[0002] At present, plastic products are used in many parts of automobiles, and these plastic products are usually formed by injection molding through injection molds. However, the structure of many products is very complex, such as figure 1 The shell-shaped product shown in , it has a plurality of transverse protrusions 4 on the outer wall of the product 1, and a plurality of inner ribs 3 are arranged inside the product 1, and one of the inner ribs 3 is also provided with a through hole 2 . When designing the mold, the horizontal protrusion 4 on the outer wall of the product 1 can be removed from the mold by moving the side formwork horizontally, but the design of the through hole 2 on the inner rib 3 cannot be directly removed from the mold, and the inner rib 3 needs to be removed. Make a sloped top...
