Abstract
The invention discloses a simple secondary ejecting mechanism of a plastic injection mold, which comprises an ejecting rod (1), a bolt (2), a spring (22), a guide slot (23), a pin (3), a pulling rod (4), a lower ejecting plate (5), an upper ejecting plate (6), a dynamic mold plate (7) and a mold leg (8). In the invention, the pin with a slant surface is arranged under the dynamic mold plate; the sliding bolt with a slant plane hole is arranged on the upper ejecting plate; the ejecting rod is arranged on the lower ejecting plate; and the upper ejecting plate and the lower ejecting plate are connected by the pulling rod in series. For ejecting, the lower ejecting plate and the upper ejecting plate eject synchronously to perform primary ejection, and then the lower ejecting plate continues to eject alone to complete secondary ejection. The technical scheme overcomes the problems and drawbacks of narrow application range, short service life, complex structure, high cost and complex installation of the prior art are solved; and the simple secondary ejecting mechanism of the plastic injection mold has a simple and reliable structure, is easy to process and convenient to install, saves cost and can be universally used and standardized.
Description
Technical field
The present invention relates to the demoulding ejecting mechanism of injection mold, specifically be meant to be applied in Double Tops plate injection mold, be used for the simple and easy secondary ejecting mechanism that secondary ejects a kind of injection mold of injection-molded item purposes.
Background technology
Because some injection-molded item shape special, perhaps require goods to separate automatically during volume production and come off, when injection mold can't separate when coming off automatically with once ejecting goods, just need increase more once to eject action.The action design of ejecting like this is called secondary and ejects.
The mode of the secondary ejecting mechanism of prior art injection mold is numerous, divides pneumatic/fluid pressure type, top plate type by drive form, divides single cover top board, two cover top plate type again by the top board combining form; There are spring/elastic rubber, secondary sleeve pipe thimble standard set-up (as the FW1800 among the DME) in the mechanism that single cover top board execution secondary ejects, and there are jack catchs type, voussoir swinging hook type, cam swing formula etc. in the mechanism that Double Tops plate execution secondary ejects; Wherein, spring/elastic rubber is applicable to small mould, and because spring or elastic rubber are directly stressed, so the elastic fatigue of being easy to generate shortens service life, needs often to change; Secondary sleeve pipe thimble standard set-up and jack catchs type, voussoir swinging hook type, cam swing formula exist complex structure, cost height, loaded down with trivial details problem are installed; Therefore, there is the drawback that applicable surface is narrow, the life-span is short in prior art medi-spring/elastic rubber mode, and other modes exist complex structure, cost height, loaded down with trivial details problems and shortcomings are installed.
