UPPER Mould

The mold itself has no upper and lower touch points. This is like: two bricks are put together. We can’t talk about bricks and bricks in a targeted way. If there is a concept of the upper mold, people who have studied physics Know that this is a reference or reference point.thin wall mold
The most common mold is two molds. The so-called two molds have two main cavities. You can open the mold left and right, or you can open the mold up and down. Therefore, only under the working conditions of the upper and lower molds. The upper mold, the meaning of the lower mold exists.
Generally speaking, the upper and lower mold opening is most common in punching machines, pouring machines, hydraulic machines, and in this case, the upper mold is also called a dynamic mold, and the lower mold is called a static mold. This is because the mechanical mechanism is used when the mold is opened. Drive the moving mold up and complete the mold opening action, so the upper and lower molds appear.
In general, according to the matching structure of the upper and lower molds of the compression film, the compression molds are divided into three types: overflow type, non-flooding type, and semi-flooding type. The mold alignment unit is also called the alignment guide device of the mold blade. It is necessary to maintain the alignment of the upper mold and the lower mold and shorten the preparation time according to the requirements of the product accuracy and production quantity.
