Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Examples
Referring to fig. 1-4, the reverse ejection mechanism in the mold comprises a cavity insert 1, an ejector plate 8 and a driving mechanism, a cavity insert backing plate 2 is arranged below the cavity insert, the ejector plate is correspondingly arranged inside the cavity insert backing plate, the driving mechanism comprises a driving device 3 (directly controlled by a control system of an injection molding machine), two transmission rods 6, two connecting rods 4, two fixed blocks 7 and two ejection blocks 9, a telescopic block 11 is fixedly arranged on an output shaft of the driving device, two connecting shafts 12 are integrally arranged on the side wall of the telescopic block, each connecting shaft is connected with one transmission rod through one connecting rod, the two fixed blocks are arranged close to two side edges of the ejection plate, each fixed block is provided with an accommodating groove 10 in an upward split mode, the two ejection blocks are correspondingly arranged inside the two accommodating grooves, and each transmission rod penetrates through one fixed block and is.
The working principle is as follows: the driving device drives the telescopic block to perform telescopic action, the connecting rod and the transmission rod drive the ejection block to overturn in the accommodating groove, and when the ejection block is overturned, the ejection plate is driven to perform ejection and demolding.
In this embodiment, the two side edges of the cavity insert base plate are provided with a recess groove 5 for the ejection block to turn over and recess.
In the present embodiment, the driving means employs a driving cylinder.
In this embodiment, the action directions of the two transmission rods are opposite, so that the two ejection blocks can respectively drive the ejector plate to act, and then the product can be ejected and demoulded.
The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
