Injection molding learning method is introduced:
A, the basic principle of injection molding:?
Injection molding machine using plastic heated to a certain temperature, can melt into liquid properties, the molten liquid with high pressure injection into the closed cavity, after cooling and shaping, open the mold after the top to get the required plastic products.
Two, injection molding of the four elements:?
1.plastic mold 2.injection molding machine 3.plastic raw materials 4.molding conditions?
Three, plastic mold?
Most of the two-platen molds, three-platen molds, but also some of the line position mold with slider.
Basic structure: 1. male mold (lower mold) male mold fixed plate, male mold auxiliary plate, ejector plate, male template. 2. Female mold (upper mold) Female mold plate, female mold fixed plate, into the rubber ring, positioning ring. 3. Equalization system Cooling. Stabilize (equalize) the temperature of the mold.
Four, injection molding machine?
Mainly by the plasticizing, injection device, mold device and transmission mechanism; electrical drive motor, motor drive oil pump, oil pump generates oil pressure, oil pressure drives the piston, piston driven machinery, machinery to produce action;?
1, according to the injection method can be divided into:?
1. Horizontal injection molding machine 2. Vertical injection molding machine 3. Angle injection molding machine 4. multi-color injection molding machine?
2. According to the mode of mold clamping can be divided into:?
1.Direct Pressure Injection Molding Machine 2.Crankshaft Injection Molding Machine 3.Direct Pressure, Crankshaft Compound Type?
3. According to the feeding method can be divided into:?
1. Plunger injection molding machine 2. Single-pass screw injection molding machine 3. Reciprocating screw injection molding machine?
