What are the elements of plastic mold design?

Material mold is mainly used to make a variety of plastic products, in order to achieve the desired effect, in the design of plastic molds to consider a lot of factors.
Since the final effect of plastic molds will be affected by various factors, including plastic shrinkage and error, wear and tear, so in the design of the above parameters are comprehensive analysis. In addition, we should also consider the molding machine process and structural parameters of the matching, in fact, these can be assisted by computer technology.
When the plastic mold is closed, the contact surface where the die and the convex mold work together, i.e. the parting surface is also a key. Because of its location and form of selection, will be affected by product shape, appearance, wall thickness, molding method, post-processing process, mold type, release method and molding machine structure and other factors.
In addition to this is the mold pouring system, especially the selection of gate position, mainly in favor of molten plastic in a good flow state full cavity as the basic principle, so that attached to the product of solid-state runners and gate cold material can be opened, it is easy to top out of the mold and remove, to avoid the impact on plastic products.
