Problems solved by technology

[0002] See figure 1 , there are many slanted ejectors for casting products. When forming ejectors, slanted ejector 3 is ejected at the same time, ejector plate 4 drives thimble 1 to eject product 2, product 2 is easy to stick to slanted ejector 3, and slanted ejector 3 returns to its position It is easy to press the mold at the time, causing damage to the product 2

Embodiment Construction

[0008] See figure 2 , the ejector device of the present invention, which includes an upper mold 1, a lower mold 10, an inclined ejector 7, an ejector pin 6, an upper ejector plate 3 and a lower ejector plate 4, and an end between the upper ejector plate 3 and the lower ejector plate 4 The push plate early return device 2 is used for flexible connection, and the other end is connected with spring 9 and bolt 8. When the mold is opened, the lower ejector plate 4 is ejected, and the lower ejector plate 4 is ejected twice through the push plate early return device 2 to realize The ejector pin 6 and the inclined ejector 7 are ejected at the same time, then the inclined ejector 7 stops, the ejector pin 6 continues to eject, and the product 5 is ejected, so that the product 5 will not stick to the inclined ejector 7, and the bolt 8 guides and The pressure of the spring 9 makes the lower ejector plate 4 reset accurately, which prevents the product from being molded when the inclined e...

Abstract

The invention provides a multi-lifter ejection device. After the lifter are ejected, an ejector pin continues to eject the product out of the lifter, so that the products can separate from the lifter during the resetting of the lifter rather than adhere to the lifter and the product yield is guaranteed. The multi-lifter ejection device comprises an upper mold, a lower mold, a lifter, an ejector pin and an ejector pin plate, wherein the lifter and the ejector pin are fixed on the ejector pin plate. The multi-lifter ejection device is characterized in that: the ejector pin plate has an upper ejector pin plate and a lower ejector pin plate; the lifter is fixed on the upper ejector pin plate; the lifter is fixed on the lower ejector pin plate; the upper ejector pin plate and the lower ejectorpin plate are movably connected from one end by a push plate earlier return device and the other ends of the upper ejector pin plate and the lower ejector pin plate are movably connected by a spring and a bolt.

Description

technical field [0001] The invention relates to the technical field of mold ejection devices, in particular to a multi-slope ejection device. Background technique [0002] See figure 1 , there are many slanted ejectors for casting products. When the ejector is formed, the slanted ejector 3 is ejected at the same time. It is easy to press the mold during the process, causing damage to the product 2. Contents of the invention [0003] In view of the above problems, the present invention provides a multi-slope ejector device. After the slant ejector is ejected, the thimble continues to eject the product from the slant to ensure the stable separation of the product and the slant when the slant returns. , to prevent the product from sticking to the sloping roof, and to ensure the pass rate of the product. [0004] Its technical solution is as follows: an ejector device with multiple inclined ejectors, which includes an upper mold, a lower mold, an inclined ejector, a thimble...
