Problems solved by technology

[0002] For the ejection and demoulding of deep injection molded products with large coating force and deep coating length, the prior art adopts a lever-type secondary ejection device, that is, the ejector rod is first slowly ejected with the top plate, so that the coating When the product on the core is loose, the lever-type seesaw is used to pry the ejector rod to accelerate the ejection of the loose product from the core, shortening the time of the entire ejection process to improve the efficiency of product demoulding; the lever type is applicable For one-to-one ejection, that is, one lever is matched with one

Abstract

The invention discloses a rack-type speed-multiplying secondary ejecting device which comprises a gear (1), a top plate rack (2), a slide rack (3), a push plate (4), a push top plate (41), a push plate top compounded rod (5), a stub bar pull top rod (6), a product top rod (7) and a positioning rod (8). According to the invention, the device composed of the parts is adopted, in operation, when a product and a mold core are loose, the upper surface of the slide rack which moves forward along with the push top plate is close and contacted with the lower end of the positioning rod, and the positioning rod butts against the slide rack, and under the rotation effect that the gear, the top plate rack and the slide rack are meshed mutually, the top plate rack pushes the top plate to drive the stud bar pull top rod and the product top rod, and pushes a product and a cold stub bar to be separated from the mold core and the push plate forward in an acceleration mode at the speed twice of that of the push plate. With the adoption of the technical scheme, the problems and defects of application limit and low efficiency for the prior art are overcome, and the aims of expanding the application range and improving the mold removing efficiency further are achieved.

Description

technical field [0001] The invention relates to an ejection and demoulding device for an injection mold, specifically a rack-type double-speed two-stage device for ejecting and demoulding a deep-type injection molded product with a relatively large coating force and a relatively deep coating length by an injection mold. Second ejection device. Background technique [0002] For the ejection and demoulding of deep injection molded products with large coating force and deep coating length, the prior art adopts a lever-type secondary ejection device, that is, the ejector rod is first slowly ejected with the top plate, so that the coating When the product on the core is loose, the lever-type seesaw is used to pry the ejector rod to accelerate the ejection of the loose product from the core, shortening the time of the entire ejection process to improve the efficiency of product demoulding; the lever type is applicable For one-to-one ejection, that is, one lever is matched with on...
