Problems solved by technology

Use time delay control to realize the glue feeding of different materials. In the case of products with different sizes, the products are prone to under-injection and flashing
The timing control of the needle valve will also be affected by the viscosity coefficient of the material during molding, making the needle valve control process unstable, which may lead to unstable product quality, and the long debugging time will lead to too long production lead time and the use of the machine. rate is not high

Abstract

The invention discloses a forming manner for realizing automatic setup of needle valve opening and closing. The forming manner comprises the following control steps: 1, utilizing a pressure sensor tocollect pressure data in each cavity during the injection molding process; 2, transferring the pressure data to a control module, utilizing the control module for analysis treatment to obtain the relation between pressure and injection molding time, and converting a pressure parameter into a time signal; and 3, utilizing the time signal to control the injection molding time in the cavity. With adoption of the forming manner, the product quality in the cavity can be monitored in real time and automatic adjustment is carried out, the setup time is shortened, the production efficiency is improved, and the problem that different high-quality products are simultaneously produced in different cavities of the same die is solved.

Description

technical field [0001] The invention relates to a molding method for realizing the automatic setting of opening and closing of a needle valve. Background technique [0002] The existing needle valve control opens the valve needle at the start of collecting the injection signal of the injection molding machine, and closes the valve needle at the end of the pressure maintaining. The time delay control is used to realize the glue feeding of different materials. When the product size is different, the product is prone to underfill and flash. The timing control of the needle valve will also be affected by the viscosity coefficient of the material during molding, which will make the needle valve control process unstable, which may lead to unstable product quality. Too long debugging time will lead to too long production lead time and machine use. The rate is not high. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of th...
