Abstract

The present invention provides a method and device for calculating a maximum projection area of a component. The method comprises the steps of establishing a sketch plane in CATIA software, projecting the outline of a component to be calculated to the sketch plane, calculating an initial projection area of the component to be calculated in the sketch plane, establish a parameter change relationship between a projection direction and a rotation axis, and calculating and obtaining a maximum projected area of the component to be calculated based on the parameter change relationship, free parameters set in a knowledge projection optimization module by a user, the initial projection area and a maximum update number of times. In the method of the invention, through setting related parametersin the CATIA software, the maximum projected area of the component can be quickly and conveniently calculated, a complicated working time can be reduced, the working efficiency can be improved, theaccuracy is high, the maximum projected area of a component with an irregular shape can be calculated, and the technical problems of low efficiency, poor accuracy and large limitations in calculating the maximum projected area of a component in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a method and device for calculating the maximum projected area of ​​a part. Background technique [0002] The development of automotive plastic parts requires the use of injection molds. Before the production of injection molds, the maximum clamping force must be calculated, and the corresponding molds should be made according to the requirements of this clamping force. Clamping force refers to the locking force applied to the mold by the injection machine in order to overcome the expansion force of the melt in the cavity to the mold during injection. When the raw material is injected into the mold cavity at high pressure, it will generate a force to support the mold, so the clamping unit of the injection molding machine must provide enough "clamping force" to keep the mold from being stretched. The size of the clamping force is related to the projected area of ​​the pro...
