Connect the injection molding machine blowing function, the pneumatic valve control signal into the controller blowing output point, open the controller blowing function can be.
The machine has a blowing terminal, install the pneumatic solenoid valve can be, such as the machine does not lead out of the terminal, it is necessary to lead from the computer board, and then in the computer screen to set the parameters of the moving mold fixed mold can be.
The working principle of the injection molding machine is similar to that of the syringe, it is with the help of the screw (or plunger) of the thrust, will have been plasticized in a molten state (i.e., viscous state) of the plastic injected into the closed cavity, after curing and shaping of the products obtained after the process.
Injection molding is a cyclic process, each cycle mainly includes: dosing - melting and plasticizing - pressure injection - mold filling and cooling - open the mold to take parts. After removing the part, the mold is closed again for the next cycle.

Injection Molding Machine Repair and Maintenance:
1, check whether the running mold is in a normal state: whether there is a low-pressure mold lock protection; Active parts such as guide pillar, roof rod, line position is worn, lubrication is good? Requirements for at least 12 hours to add oil, special structure to increase the number of refueling. Whether the screws and clamps of the fixed template of the mold are loose; normal production condition: check whether the defects of the products are related to the mold.
Discharged from the machine to carry out a comprehensive inspection of the mold and rust treatment: wipe dry the cavity, core, ejector mechanism and rows and other parts of the water and spray mold rust inhibitor or grease. Down after the mold should be placed in a designated place and make a record:
(1) mold condition: intact or to be repaired.
(2) Rust prevention treatment when the mold is discharged.
2, quarterly routine inspection: mainly for more than two months placed in the mold is not used to clean up maintenance.
(1) Open the mold, check the effect of internal rust prevention, there are abnormalities, must be re-rust treatment. Long-term non-use of the mold shall be coated with grease.
(2) Put back to the original position and make a record.
3, maintenance notes:
(1) non-professional maintenance personnel or without the permission of professional maintenance personnel, not to dismantle the mold maintenance.
(2) the production process of small faults, adjusting the machine can be solved according to the situation. Such as: 2.1 into the rubber mouth sticky mold: should be a copper needle in the feed nozzle knocked out, not with a steel needle and other hard objects to knock the mold. 2.2 cavity slight mold marks, according to the cavity of the smoothness of the choice of polishing materials. Grainy surface can not use sandpaper and other polishing materials, generally use copper brush dipped in diamond plaster or emery slurry brushing, completed by professional maintenance personnel.
2.3 products stick to the mold: generally use hot plastic to cover the product and ejection parts, to be cooled after ejection. If you use fire to take care not to damage the surface of the mold.
(3) professionals to repair the mold, not to change the structure at will, the need to change the structure must be agreed by the quality engineering department before proceeding.
(4) to ensure the quality of maintenance, select the appropriate equipment, materials, tools and their solutions to the problem, in order to complete the fastest speed.
4, quality records: injection molding machine and mold maintenance record sheet.
Purpose: To standardize the use and maintenance of plastic injection molds, reduce mold damage, to ensure that the quality of production to meet customer demand.
Responsibilities: This standard must be qualified by the training of injection molding technicians 2.2 injection foreman is responsible for the implementation and inspection supervision, the supervisor regularly supervise.
