Background

An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification.

The injection mold consists of a movable mold and a fixed mold, wherein the movable mold is arranged on a movable template of the injection molding machine, and the fixed mold is arranged on a fixed template of the injection molding machine. And when the mold is opened, the movable mold is separated from the fixed mold so as to take out the plastic product. In order to reduce the heavy mold design and manufacturing effort, injection molds mostly employ standard mold bases.

At present, the finished product of moulding plastics of current horizontal injection mold is most directly during the falling into finished product frame, causes the finished product damage of moulding plastics, though partial injection mold installs ejection of compact slide, because the buffering material reduces the finished product's of moulding plastics damage, however, current ejection of compact slide simple structure can't carry out the regulation of length of sliding according to the finished product frame of the different degree of depth, and the application scope of blanking buffering tray is than low, is difficult to use widely.
