Problems solved by technology

However, if the wrapping force is too large, it will cause cracking and deformation when the product is ejected. Therefore, it is necessary to calculate the shrinkage wrapping force of thermoplastic injection molding products.
The tightening force calculated by the existing tightening force calculation method is inaccurate and often too large

Abstract

The invention discloses a cylindrical mold core wrapping force calculation method which comprises the following steps: acquiring a wrapping force parameter under the current condition; according to the enclasping force parameters under the current condition, using an existing enclasping force calculation formula to calculate the initial enclasping force; according to the initial wrapping force and a preset correction table, calculating an experience deviation; and calculating a final wrapping force according to the initial wrapping force, the experience deviation and a corresponding correction coefficient in a preset correction table. Meanwhile, the invention discloses a corresponding system and a server. According to the method, the empirical deviation is calculated through the preset correction table, and the packaging force is corrected through the empirical deviation and the correction coefficient in the preset correction table, so that the relatively accurate packaging force is obtained.

Description

technical field [0001] The invention relates to a method, system and server for calculating the tightening force of a cylindrical core, and belongs to the field of calculating the tightening force. Background technique [0002] During the injection molding process, the plastic part in the cavity wraps the core tightly due to cooling and shrinkage, resulting in a tight force on the core. The demoulding force to push the plastic part out of the cavity must be able to overcome the frictional resistance of the tight force , and after the product molding process, in order to ensure that the product can stay on the male mold side, the tightening force on the male mold side of the product must be greater than the tightness on the core from the female mold side of the product. However, if the wrapping force is too large, it will cause cracking and deformation when the product is ejected. Therefore, it is necessary to calculate the shrinkage wrapping force of thermoplastic injection ...
