What do you know about the three elements of buying an injection molding machine?

    Injection molding machine, also known as injection molding machine or this injection machine, is a very common machine in factories in China. Workers in factories call it beer machine. Its working principle is that the injection molding machine heats plastic and applies high pressure to molten plastic to spray it to fill the mold cavity. We all know the above principle. Let's talk about the three elements of purchasing an injection molding machine. Don't you know this.

    Three elements of purchasing injection molding machine

    The three elements of purchasing an injection molding machine are placing, filling and locking

    Fit: that is, the mold can be installed into the mold locking system of the injection molding machine. The capacity modulus of the injection molding machine can be queried from the mold locking system in the technical parameters of the injection molding machine.

    Locking: during injection molding production, the injection molding machine can tightly lock the mold, and will not expand or produce sharp edges due to injection during injection molding.

    The following figure is the schematic diagram of the mold locking system of the injection molding machine, that is, the mold width dimension L ＜ the pull rod spacing L 'in the horizontal direction of the injection molding machine. The mold height dimension h can be greater than the pull rod spacing H 'in the vertical direction of the injection molding machine, but shall not be greater than the vertical dimension H "of the template. No part of the mold shall extend beyond the template. Mold thickness w ＜ injection molding machine Zui large mold thickness W '.

    Principle of injection molding machine

    Full shot: in theory, Injection molding machine with Zui large injection volume (weight) if it is greater than the weight of the injection molded part, the product can be fully injected. In order to ensure the stability of the product, a certain amount of glue needs to be reserved in the actual injection production. Therefore, when selecting the injection molding machine, 80% ~ 90% of the Zui large injection quantity of the injection molding machine is often taken as ≥ the weight of the injection molded part. If it cannot meet the requirements, the injection molding machine of a higher model should be selected.
