Problems solved by technology

There are following defects in this top mold mechanism: (1) the diameter of the support rod is too large, and it takes up a lot of space
(4) Reduce the service life of the mold
The number of ejector rods is small, so that the mold is subjected to uneven force, easy to deform, and accelerates mold wear
(5) Leading to template explosion
Long-term uneven force on the formwork can easily cause the formwork to explode

Abstract

The invention provides a main assistant multi-top injection ejecting molding mechanism, which comprises a movable template, an ejecting cylinder, a support bar, an ejecting plate and an ejecting bar. The ejecting plate is connected with the ejecting bar which passes through the movable template. The invention is characterized in that: the movable template is provided with a reinforcing plate, which is in parallel with a main body of the movable template; the ejecting plate is arranged between the reinforcing plate and the main body of the movable template; the support bar passes through the ejecting plate, two ends of the support bar are fixedly connected with the reinforcing plate and the main body of the movable template; the ejecting cylinder comprises a main ejecting cylinder and an assistant ejecting cylinder, wherein, the main ejecting cylinder is directly connected with the reinforcing plate and a piston bar of the main ejecting cylinder is connected with the ejecting plate; besides, the assistant ejecting cylinder is arranged above the main body of the movable template and a piston bar of the assistant ejecting cylinder is connected with the ejecting plate. The ejecting molding mechanism has enough intensity, rigidity and large and uniform ejecting power, thus causing a mold to gain uniform and balanced force, prolonging the service life of the mold and effectively improving production efficiency and qualification rate of the product.

Description

technical field [0001] The invention relates to an injection molding top mold structure, in particular to a main and auxiliary multi-top injection molding top mold mechanism. Background technique [0002] The ejector mechanism of the injection molding machine is used to eject the molded product from the mold. Most of the existing injection molding machines adopt a single-cylinder direct-push top mold mechanism. Such a top mold mechanism such as figure 1 As shown, the ejector cylinder 1 is fixedly connected with the movable template 3 through the support rod 2, the ejector plate 4 is connected with the piston rod of the ejector cylinder 1, the ejector plate 4 is connected with the ejector rod 5 at the same time, and the support rod 2 Through the ejector plate 4 , it is equivalent to the guide rod of the ejector plate 4 , and the ejector plate 4 can be driven by the ejector cylinder 1 to move along the support rod 2 . There are following defects in this top mold mechanism: ...
