Mold itself does not have the upper and lower touch of the points, which For example: two bricks put together, we can not specifically on the brick, bricks, if there is the concept of die on the mold, the people who studied physics We all know that this requires a reference or reference point. Precision mold

The most common mold is the two molds, the so-called two molds, there are two main cavity, you can open the mold, you can also open the mold up and down, therefore, only in the upper and lower mold work, before A punch, the meaning of the mold exists.

In general, the upper and lower mold is the punch, pouring machine, hydraulic machine is the most common, and in this case, the upper die is also called the dynamic mode, the lower die is called static mode, this is because, when the mold is a mechanical mechanism Drives the moving mold to rise, completes the mold opening movement, therefore, has appeared the upper mold and the lower mold.

In simple terms, the mold has pre-forming device, positioning device and ejection device. The general configuration for the panel, A board (former model), B board (after the model), C board (square iron), floor, thimble panel, thimble floor, and guide posts, back to the needle and other spare parts.

Above the mold frame is a typical mold frame structure. The right part is called the upper mold, the left part is called the lower mold. Injection molding, the upper and lower mold will be the first combination, so that plastic molding in the upper and lower module forming part. Then the upper and lower mold will be separated, and by the following mold-based ejection device to launch the finished product.

Die on the die (front)

Configured as a molded part or as a molded part.

Part of the flow path [hot nozzle, hot runner (pneumatic part), ordinary flow].

Cooling part (water hole).

Die under the mold (after the mold)

Configured as a molded part or as a molded part.

Launch device (finished push plate, thimble, cylinder needle, inclined top, etc.).

Cooling part (water hole).

Fixtures (head, iron and needle guide plate, etc.).
