What is an injection mold? Today I will tell you thoroughly that thousands of products are produced by him(Part 5)

According to the structure, plastic molds generally consist of several parts such as mold base, mold core, auxiliary parts, auxiliary system, auxiliary settings, and dead corner processing mechanism.

  1. Mold base:
    Generally, we do not need to design it. You can order it directly from the standard mold base manufacturer, which greatly saves the time required to design the mold, so it is called the plastic mold standard mold base. It forms the most basic frame part of the plastic mold.
  2. Mold:
    The mold core part is the core part of the plastic mold, and it is the most important component of the mold. The forming part of the plastic product is inside the mold core, and most of the processing time is spent on the mold core. However, compared with some relatively simple molds, it does not have a mold core part, and the product is formed directly on the template. Most of the early plastic molds were like this and were relatively backward.
  3. Auxiliary parts:
    Commonly used auxiliary parts for plastic molds include positioning rings, injection bushings, ejector pins, grab pins, support columns, ejection plate guides, guide bushes, garbage nails, etc. Some of them are standard parts and you can order the mold base directly. When ordering together, some parts need to be designed by yourself.
  4. Auxiliary system:
    There are four auxiliary systems for plastic molds: pouring system, ejection system, cooling system and exhaust system. Sometimes, because the plastic materials used need to be heated to a very high temperature, some molds will also have a heating system.
  5. Auxiliary settings:
    The auxiliary equipment of the plastic mold includes lifting eye holes, KO holes (top stick holes), etc.
  6. Dead corner processing structure:
    When a plastic product has dead corners, the mold will also have one or more structures to deal with the dead corners. Such as slider, inclined roof, hydraulic cylinder, etc. In most domestic books, this kind of mechanism for dealing with dead ends is called “plowing mechanism”.
