To understand the action of injection molding machine

To understand the action of injection molding machine program now let's learn about injection molding machine operating procedure. Nozzle forward - - pressure - pre plastic injection to pour shrinkage, the nozzle back to cooling, mould - out - needle back to open the door, shut the door to clamping, the nozzle to move forward. 1, injection molding machine operating items: injection molding machine operating projects include control keyboard, vacuum forming machine, electric control cabinet and the hydraulic system operation in three aspects. Movement and feeding movement respectively by injection process, injection pressure, injection rate, ejection type choice, cylinder paragraphs temperature and current, voltage monitoring, the adjustment of the injection pressure and back pressure, etc. 2, the injection process action choice: general injection molding machine can be manually operation, can also semi-automatic and fully automatic operation. Manual operation is in a production cycle, every action is accomplished by the operator operating switches. Usually only choose when commissioning the variable. Semi-automatic operation when the machine can automatically complete a working cycle of action, but every production cycle after the completion of the operator must pull open door, remove the artifacts, close the door again, the machine can continue to the next cycle of production. Operation on the fully automatic injection molding machine in the completion of a working cycle of action, can work automatically into the next cycle. In the normal work continuously in order to control and adjust the process without stopping. But must pay attention to, such as the need to fully automatic work: ( 1) Midway don't open the door, or fully automatic operation interruption; （ 2) To timely loading; （ 3) If choose the electric induction, should pay attention not to cover the magic eye closed. In fact, in the automatic operation is usually need to temporary stop halfway, such as to machine the mold injection mold release agent, etc. During normal production, generally choose semi-automatic or fully automatic operation. At the start of the operation, should according to the production need to select operating mode ( Manual, semi-automatic or fully automatic) And the corresponding manual, semi-automatic or fully automatic switches. Semi-automatic and fully automatic working procedure is determined by the line itself is good, the operators only need to change the size of the speed and pressure on electric map, the length of time, the number of thimble, etc. , by the operator at the wrong button and make the working procedures of chaos. When a cycle of each action before adjustment is in order, should choose the manual operation, each movement is normal, and then choose the semi-automatic or fully automatic operation.
