Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to figure 1, Fig. 2 and Fig. 3, a kind of novel material injection device applied on die casting machine of the utility model, including material
Kettle body 1, bushing 2, piston rod 3, piston ring 4, material injection tube 5, shooting nozzle 6 and material pot inner sleeve 7.
Bushing 2 is equipped with working chamber 21 in material kettle body 1 in bushing 2, one end of piston rod 3 is equipped with multiple slots 31,
The quantity of piston ring 4 is suitable with the quantity of slot 31, and the one-to-one correspondence of each piston ring 4 is sleeved on slot 31, and the piston after installation
Ring 4 is in contact with the inner wall of working chamber 21, i.e., one end of piston rod 3 is movably arranged on by piston ring 4 in working chamber 21.
The bottom that piston rod 3 is located at one end in working chamber 21 is additionally provided with axial hole 32, and is additionally provided with radial direction in piston rod 3
