I, vertical injection molding machine
1, the injection device and clamping device is in the same vertical centerline, and the mold is along the up and down direction of opening and closing. Its footprint is only about half of the horizontal machine, therefore, converted into a footprint productivity of about two times.
2. It is easy to realize insert molding. Because the mold surface facing up, inserts into the positioning is easy. It is easy to realize fully automatic insert molding by combining the lower template fixed, upper template movable machine, belt conveyor and robot.
3, the weight of the mold is supported by the horizontal template for the up and down opening and closing action, will not occur similar to the horizontal machine due to the gravity of the mold caused by the front fall, so that the template can not open and close the phenomenon. It is helpful to keep the precision of machine and mold persistently.
4, through a simple robot can take out each cavity of the plastic parts, which is conducive to precision molding.
5, the general clamping device around the open, easy to configure all kinds of automation devices, adapted to complex, delicate products automatic molding.
6, pull the belt conveyor is easy to realize the string over the middle of the mold installation, easy to realize the molding of automatic production.
7, easy to ensure the consistency of resin fluidity and mold temperature distribution within the mold.
8. Equipped with rotating table, moving table and tilting table, it is easy to realize insert molding and in-mold combination molding.
9, small batch trial production, the mold structure is simple and low cost, and easy to unload.
10, the test of many earthquakes, vertical machine due to the low center of gravity, relative to the horizontal machine seismic better.
Two, horizontal injection molding machine
1, even if the large machine due to the low body, for the placement of the plant without height restrictions.
2, the product can be automatically dropped occasions, do not need to use a robot can also realize automatic molding.
3. Due to the low body, it is easy to supply materials and easy for maintenance.
4, molds need to be installed by crane.
5.Under the arrangement of many sets side by side, the molded products are easy to be collected and packed by the conveyor belt.
Three, corner injection molding machine
Corner injection molding machine injection screw axis and the axis of motion of the template clamping mechanism are arranged perpendicular to each other, the advantages and disadvantages of its between vertical and horizontal. Because of its injection direction and mold parting surface in the same plane, so the corner injection molding machine is suitable for the opening of the side gate of the non-symmetrical geometry of the mold or molding center does not allow traces of the gate products.
Four, two-color injection molding machine
Can be a one-time injection of two colors of the injection molding machine, can meet the requirements of consumers on the appearance of the user can make the user to use the product more comfortable.
Fifth, multi-station molding machine
The injection device and mold closing device has two or more working positions, can also be injection device and mold closing device for a variety of arrangements.
Six, electric injection molding machine
All-electric injection molding machine can not only meet the needs of special purposes, but also has more advantages than ordinary injection molding machine.
Another advantage of the all-electric injection molding machine is that it can reduce noise, which not only benefits the workers, but also reduces the cost of investment in sound-proof production plant.
Maintenance of the injection molding machine
1, daily inspection
Every day, we must check and adjust the safety facilities, must ensure that the safety facilities are normal, in order to use the operation of the machine; check the amount of oil in the lubricating oil tank must be added to the same brand of new oil; check the oil level of the hydraulic oil tank, if the oil level drops below the center line of the level gauge, then add the hydraulic oil to the center line! Above, must add the same grade of new oil; the first time into operation after 1000 hours, need to replace or clean the suction filter, hydraulic oil, clean the tank; when running 5000 hours or up to one year, need to replace or clean the air filter and hydraulic oil, pay attention to the old and new hydraulic oil can not be mixed; when running 20000 hours or up to 5 years, check, replace the hydraulic cylinder seals and wear rings, and Replace the high-pressure hose; every 3 years, replace the controller (host) battery; every 5 years, replace the battery on the operating panel.
2, pay attention to lubrication
Injection molding machine use process, you need to regularly observe the injection molding machine lubrication point is in normal working condition. Pay attention to each lubrication time must be enough to ensure that the entire lubrication system of each lubrication point to get good lubrication. The lubrication modulus (interval time) and each lubrication time of the machine are realized through the reasonable setting of computer parameters. Regularly observe the working condition of the lubrication system and keep the lubricant in the oil tank at a reasonable level. If poor lubrication is found, it should be lubricated in time and the lubrication condition of each lubrication point should be checked to ensure that the machine is well lubricated.
3, check the air filter
The role of the oil tank air filter is the oil tank breathing, and prevent the outside world of dust and other dirt into the oil tank, so it is a very important parts, the need for regular maintenance. The air filter is mounted on the top of the fuel tank, to clean, loosen the cover, replace the air filter element, and then re-tighten the cover. Note that the cap must be tightened, otherwise the oil will spill out.
