The gate optimization analysis results of the 24 inch TV surface frame mold

(1) the following figure shows the 24 inch color TV surface frame mold designed and manufactured by Jinan Shijin experimental machine factory 1 to a mold company that pays attention to the interests of consumers. Four latent gates (gate diameter is 1.2mm) are used, and the pressure distribution is shown in Figure 1

the pressure at the nozzle is 136.87mpa, and the pressure at the latent gate is 81.98mpa. 11 in the figure, various experimental curves are selected: force displacement, force time, force deformation, stress-strain, etc. the average pressure on the side of beryllium copper inserts (shown in the black box) at the left and right gates is 71.81mpa. In practical use, beryllium copper inserts are unreasonable in structure, poor in strength, and close to the gate. Under pressure, there are safety hazards, they bend outwards. 12. The console is separated from the host and bent and deformed

(2) after analysis and optimization, three latent gates (gate diameter is 1.2mm) are used, and the pressure distribution is shown in Figure 2 below

the pressure at the nozzle is 104.81mpa The pressure at the two latent gates below is 55.05mpa

compared with the above analysis results, it can be seen that when using the optimized 3-point pouring, the pressure at the gate is small, which is better than the original design of 4 gates. (end)
