What basic principles should be followed in the design of die casting mould?
In the design of die-casting die, the following basic principles should be followed: in the design of die-casting die, the mold structure should be selected according to the batch size of the plastic parts.For the resin production batch small and simple shape plastic parts, « adopt mobile simple pressing die structure.The fixed die casting structure should be used for the production of large or complex plastic parts.
2) the die-casting structure of the design should be simple, small and light in order to reduce the labor intensity of operation.
3) for die-casting of embedded parts, it is necessary to make the embedded parts easy to be placed, and there should be enough plastic thickness around the embedded parts so that the embedded parts can be firmly fixed, and the general thickness can be 2~4mm.In order to make the embedded panels firmly embedded, it is better to choose the transfer mode structure for the larger ones.
4) when designing the cavity, if the plastic part has special side hole and convex platform, the cavity design adopts the Mosaic structure, and the core mechanism should be designed so as to make the mold.
5) it is easy to die after pressing the plastic parts, and the mold cavity should be provided with the striation Angle.
6) the top part system of the pressing mould shall be designed to be evenly distributed, so that the force of the plastic parts shall be uniform when the top piece is made, without deformation.
7) the parts of pressing die, such as die sets, concave dies and convex molds, shall have certain strength and rigidity.
