Injection molding process technology is widely used. I hope this article can give some inspiration to friends who want to understand this knowledge.——-Chloe.
Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity.
Injection molding is a very common plastic molding method. In order to let you better understand the injection molding machine, we have sorted out the content of the injection molding machine and the molding process of general plastics for you.
According to the shape of the injection molding machine, according to the arrangement of the injection device and the clamping device, it can be divided into vertical type, horizontal type and vertical-horizontal composite type.
Our article today revolves around vertical injection molding machines.
a. Vertical injection molding machine
1. The injection device and the clamping device are on the same vertical center line, and the mold is opened and closed along the up and down direction. Its floor area is only about half of that of the horizontal machine, so the productivity is about twice that of the floor area.
2. It is easy to realize insert molding. Because the mold surface is facing upwards, insert positioning is easy. Using a model with a fixed lower platen and a movable upper platen, combined with a belt conveyor and a robot arm, fully automatic insert molding can be easily realized.
3. The weight of the mold is supported by the horizontal formwork for up and down opening and closing actions, and there will be no phenomenon that the formwork cannot be opened and closed due to the front fall caused by the gravity of the mold similar to the horizontal machine. Conducive to durability to maintain the precision of machinery and molds.
4. The cavities of each plastic part can be taken out by a simple manipulator, which is conducive to precision molding.
5. Generally, the mold clamping device is open around, and it is easy to configure various automatic devices, which is suitable for automatic molding of complex and delicate products.
6. The pull belt conveying device is easy to be installed in the middle of the mold, and it is convenient to realize the automatic production of molding.
7. It is easy to ensure the consistency of the fluidity of the resin in the mold and the temperature distribution of the mold.
8. Equipped with rotating table, moving table and inclined table, etc., it is easy to realize insert molding and in-mold combination molding.
9. During trial production in small batches, the mold structure is simple and cost-effective, and it is easy to disassemble.
10. Withstood the test of many earthquakes. Due to the low center of gravity, the vertical machine has better shock resistance than the horizontal machine.
