Injection molding machine with two templates, a don't understand, known as the template;
Another block can be moved, referred to as dynamic template.
Mould are respectively through the screw and plate fixed on the two pieces of the template.
Open mold, injection molding machine template move, thus promote open the mould.
mold manufacturing, injection molding, be on the injection molding machine, begin to play. However a lot of type injection molding machine, each has its own injection molding parameters. Design the mold must be able to meet the requirements of customers with injection molding machine models, otherwise will not be able to produce.
a lot of design parameters of injection molding machine, the following key talk about several parameters related to the mold, hope that readers specific design mould is attention.
1. Injection quantity
injection quantity is the injection plastic injection molding machine in the production of a can of maximum quality ( Or volume value) , which represents the largest type injection molding machine injection molding capability. Used in the design of the mould exactly melt amount to less than the injection volume of injection molding machine. Otherwise, the product, to production.
2. Clamping force
suo life got while mold closing is injection molding machine clamping force for the template. Is needed for molding products in forming of the clamping force must be smaller than the selected rating of the injection molding machine clamping force. Otherwise, the melt is easy to run from the parting surface glue produce flash.
3. Tie spacing
in the injection molding machine using the template and the template corner four tension rod, their role is to ensure that the injection molding machine has enough strength and stiffness, also responsible for sliding template. But it tends to limit the appearance of the mould size, because mould installation from rod hanging between them.
the mould dimension cannot be greater than they are at the same time pull rod spacing, if the length of the mold size has a more than the bar spacing, then see if the mold by turning into rod workshop, if you cannot rotate into, so can only change the mould size, or change the injection molding machine.
4. Nozzle size check
injection nozzle head is spherical, commonly when choosing gate set, should = make gate set of spherical radius in accordance with the nozzle radius of the sphere. To prevent high pressure melt from the nozzle and sprue set of contact gap overflow, general gate of the sphere radius should be better than the nozzle, at the same time the mainstream way small size should be slightly bigger than a nozzle hole size, this can make the nozzle and sprue fsat registration
