  The eight elements of injection mold selection

  Single part injection molding mold

  Open mode, the dynamic mode and mold separation, and thus remove the plastic parts, said single sub-surface mold, also known as double-plate mode (two plate mold). It is the most simple and most basic form of injection molds. It can be designed into single-cavity injection molds as needed. It can also be designed into multi-cavity injection molds. It is one of the most widely used injection molds.

  Double profile injection mold

  The double split face mold has two parting surfaces. Compared with the single part type injection mold, the double part type injection mold is added in the fixed part to the middle plate which can move locally (also called the active gate Plate, which is equipped with gate, runner and die required for other parts and components), it is also called three-plate (moving template, intermediate plate, fixed template) injection mold, it is commonly used in point gate feed Of the single-cavity or multi-cavity injection mold with a mold, the middle plate in the fixed-mode guide column with the fixed template for a distance separation, in order to remove the two between the template pouring system condensate. Double parting injection mold structure is complex, high manufacturing costs, parts processing difficulties, generally not for large or large plastic products molding.

  Injection molded mold with lateral and core pulling mechanism

  When the plastic parts have side holes or side concave, the need to use the side of the movement of the core or slider molding. After the injection molding, the movable die is first moved downward for a distance, and then the slanting section fixed to the bending plate on the fixed plate is forced to move outward, and the plunger of the stripping mechanism is pushed to push the push plate, Off the core.

  Injection molded molds with active forming parts

  Due to the special structure of the plastic parts, it is required that the injection mold set the movable parts, such as the movable punch, the movable die, the movable inserts, the movable thread core or the ring, etc., Together out of the mold, and then separated from the plastic parts.

  Automatic unloading thread injection mold

  For threaded plastic parts, when the automatic demoulding is required, a threaded core or ring can be set on the mold, with a rotary mechanism or a rotary drive mechanism, or a special drive, The core or threaded ring rotates to remove the plastic parts.

  No flow injection mold

  No flow channel injection mold is used to adiabatic heating of the flow channel method, to keep the injection molding machine nozzle between a plastic cavity was molten state, so that the mold out of plastic parts without pouring system condensate. The former said adiabatic runner injection mold, the latter said hot runner injection mold.

  Right angle injection mold

  Right angle injection mold is only applicable to the angle injection molding machine, and other injection molds are different is that the mold in the molding process when the direction of feeding and opening and closing direction perpendicular. His main channel opened on both sides of the moving pattern, and its cross-sectional area is usually the same, which is different from other molds used in the injection molding machine, the end of the main channel, in order to prevent injection molding machine Nozzle and the inlet of the inlet end of the wear and deformation, can be set to replace the flow channel inserts.

  The injection mold of the mold release mechanism on the mold

  In most injection molds, the stripping device is installed in the dynamic mode side, which is conducive to the injection molding machine opening and closing system in the work of the device. In the actual production, because some of the plastic parts by the shape of the restrictions, the plastic parts to stay in the mold side of the molding better, which makes the plastic parts from the mold out, it must be set in the mold side of the mold release mechanism
