How to understand the difference between vertical injection molding machine and horizontal injection molding machine?

Mar 23, 2022

According to the arrangement of injection device and clamping device, injection molding machine can be divided into vertical injection molding machine, horizontal injection molding machine and vertical-horizontal compound injection molding machine. Their respective characteristics are as follows.

Features of vertical injection molding machine
1. On the same vertical centerline, both the injection unit and the clamping device open and close in the up and down direction. Its floor area is only about half that of a horizontal machine, so the productivity in terms of floor space is about double.
2. Easy to achieve insert molding. Because the mold surface faces up, insert placement is easy. This machine is fixed by the lower mold frame, the upper mold can be moved, and the belt conveyor device is combined with the manipulator, which can easily realize fully automatic assembly and molding.
3. The weight of the mold is supported by the horizontal template to open and close up and down, and there will be no phenomenon that the template cannot be opened and closed due to the gravity of the mold similar to the horizontal machine. Helps maintain long-lasting precision in machinery and molds.
4. Each plastic part cavity can be taken out by a simple manipulator, which is conducive to precision molding.
5. Generally, the clamping device is open and open around it. It is easy to configure various automation devices and is suitable for automatic molding of complex and delicate products.
6. The belt conveyor device is easy to be installed in series in the middle of the mold, which is convenient for molding and automatic production.
7. The fluidity of the resin in the mold and the consistency of the mold temperature distribution can be easily guaranteed.
8. In small batch trial production, the mold structure is simple, the cost is low, and it is easy to unload.
9. After many earthquake tests, the vertical machine has better seismic performance than the horizontal machine due to its low center of gravity.

Features of horizontal injection molding machine
1. That is, since the large body is low, there is no height limit for the factory where it is installed.
2. The product can be automatically dropped without using a manipulator to achieve automatic molding.
3. Due to the low body, the supply is convenient and the maintenance is convenient.
4. The mold needs to be installed by crane.
5. Multiple units are arranged side by side, and the molded products are easy to be collected and packaged by the conveyor belt.
