Simulation results of the four configurations.

Gate number/a	Filling time/s	Temperature difference at the flow front/°C	Clamping force/kN	Characteristics of welding line
I	1.444	3.7	1059	The number of pieces is more and the length is larger
II	1.291	11	907
III	1.304	20.2	821.2	The number is less and the distribution is reasonable
IV	1.055	7.4	1060
