电液复合二板直压式注塑机的锁模精度及制品质量重复精度测试

In order to further improve the precision of small and medium-sized injection molding machines, a four-cylinder interlocking internal hydraulic drive two-plate direct-pressure clamping system and an all-electric plastication system are combined to design and manufacture an electro-hydraulic composite two-plate direct-compression injection molding machine. In this paper, the newly designed injection molding machine was tested in combination with the relevant test standards. The performance of the new injection molding machine was evaluated mainly by the keying accuracy of clamping precision and product weight repeatability. The test results showed that the clamping precition and the product weight repeatability of the newly designed injection molding machine achieved the technique conditions of the standard normal injection molding machines,and the slope of the tie rods had reached the standard of precision injection molding machine, but the product repeatability had a slight gap to the standard of precision injection molding machine.
