Classification Of Injection Mold

Classification Of Injection Mold

1. Automatic unloading injection mold

 For threaded plastic parts, when the automatic stripping is required, a rotatable screw core or ring can be set on the mold, using a mold opening action or a rotating mechanism of the injection molding machine, or a special transmission device to drive the thread The core or threaded ring rotates to release the plastic part.

2. No flow injection mold

The no-channel injection mold refers to the method of adiabatic heating of the flow channel, keeping the plastic between the cavity of the injection molding machine nozzle in a molten state, so that no molding system can be used for molding when the mold is removed. The former is called a heat-insulating runner injection mold, and the latter is called a hot runner injection mold.

3. Right angle injection mold

Right-angle injection molds are only suitable for angle injection molding machines. Different from other injection molds, the direction of feeding of these molds is perpendicular to the direction of opening and closing molds during molding. His main channel is set on both sides of the moving and fixed mold parting surface, and its cross-sectional area is usually constant. This is different from other injection molding machine molds. The end of the main flow path is to prevent injection molding machine. The nozzle and the inlet of the main channel are worn and deformed, and replaceable runner inserts can be provided. 

4. Demolding mechanism injection mold on fixed mold

In most injection molds, the demolding device is installed on the side of the movable mold, which is beneficial to the ejector device in the mold opening and closing system of the injection molding machine. In actual production, because some plastic parts are subject to shape restrictions, it is better to leave the plastic parts on the side of the fixed mold for better molding. This causes the plastic parts to escape from the mold and must be set on the side of the fixed mold mechanism.
