How much do you know about the three elements of buying injection molding machine?

Injection molding machine, also known as injection molding machine or injection machine, is a very common machine in our factory. The workers in the factory call it beer machine. Its working principle is that the injection molding machine heats the plastic and applies high pressure to the molten plastic to spray it to fill the mold cavity. It is estimated that everyone knows the above principle. Now let’s talk about the three elements of purchasing injection molding machine, which you don’t know.

Three elements of purchasing injection molding machines
The three elements of purchasing injection molding machines are to put them down, shoot full and lock
Put it down: that is, the mold can be installed in the mold locking system of the injection molding machine. The capacity modulus of injection molding machine can be inquired from the part of the locking system in the technical parameters of the injection molding machine.
Lock: injection molding machine tightly locks the mold during injection molding, and will not expand or generate a drape during injection molding.
The following figure is a schematic diagram of the injection molding machine locking system, that is, the width dimension of the mold L is less than the distance L of the horizontal tie rod of the injection molding machine. The height dimension h of the mold can be greater than the distance H “of the vertical pull rod of the injection molding machine, but not greater than the vertical dimension H” of the formwork. No part of the mold should extend beyond the formwork. The thickness of the mould W is less than the maximum die thickness of the injection molding machine w ‘.

Full injection: theoretically speaking, the maximum injection volume (weight) of the injection molding machine is greater than the weight of the injection part, and the product can be fully injected. In order to ensure the stability of the product in the actual injection production, it is necessary to reserve a certain amount of injection, so when selecting the injection molding machine, 80% – 90% of the maximum injection volume of the injection molding machine is considered to be full injection, The injection molding machine of a larger type should be selected.
