11 Claims

1. A method for manufacturing double-layer fair mugs, comprising the steps of, a shell (84) processing consisting of:

A1, taking a first round piece (8) for stamping step-by-step thereon to obtain a first shell semi-finished product (81);

A2, performing a cropping operation on the first shell semi-finished product (81) to obtain a second shell semi-finished product (82);

A3, shaping, cutting and flattening for the second semi-finished product (82) to obtain a third shell semi-finished product (83); and

A4, notching at the bottom and drilling for the third shell semi-finished product (83) to obtain the shell (84) with a groove (841) and a vacuum hole (842) at the bottom thereon;

a liner (94) processing consist of:

B1, taking a second round piece (9) for stamping step-by-step thereon to obtain a first liner semi-finished product (91);

B2, performing a molding mouth operation for the first liner semi-finished product (91) to obtain a second liner semi-finished product (92), and a mouth of the second liner semi-finished product (92) has a welding surface (93) concave inwardly in its diameter direction; and

B3, cutting and flattening for the second liner semi-finished product (92) to obtain the liner (94);

a cup body (101) processing consist of:

C1, performing a mouth matching operation for the shell (84) and the liner (94), and then welding an upper end of the liner (94) onto an upper end of the shell (84) to obtain a cup body semi-finished product (100) with an insulation layer; and

C2, polishing a mouth of the cup body semi-finished product (100), and then adopting a water outlet form equipment to the cup body semi-finished product (100) for stamping a water outlet operation to obtain the cup body (101);

wherein the water outlet form equipment comprises an equipment platform (1) movable disposed, a driving component (2), a water outlet form block (3), an adjusting element (4), a clamping part (5) and a supporting member (6);

wherein the clamping part (5) is movably provided on the equipment platform (1) and the clamping part (5) is further provided with a shaping groove (51); the driving component (2) passes through the supporting member (6), the adjusting element (4) is provided on the driving component (2) and goes through from the supporting member (6);

wherein the water outlet form block (3) is slidingly provided on the adjusting element (4), the driving component (2) drives the adjusting element (4) to slide back and forth in a vertical direction, and the water outlet form block (3) moves synchronously with the adjusting element (4) in a horizontal direction and slides along a direction close to or away from the shaping groove (51); and

wherein stamping the water outlet operation consists of:

D1, firstly activating the driving component (2) to move the adjusting element (4) upwardly into place, and then taking the cup body semi-finished product (100) to place on the adjusting element (4);

D2, secondly activating the equipment platform (1) to move the clamping part (5) in a direction close to the adjusting element (4), wherein the clamping part (5) clamps on an outside of the cup body semi-finished product (100) and pushes the adjusting element (4) together with the cup body semi-finished product (100) downwardly into place;

D3, thirdly individually pushing the water outlet form block (3) via the driving component (2) to slide horizontally into place in a direction close to the shaping groove (51), and meanwhile punching the water outlet on the cup body semi-finished product (100) to obtain the cup body (101); and

D4, lastly driving the clamping part (5) via the equipment platform (1) to move upward, the driving component (2) drives the adjusting element (4), the cup body (101) and the equipment platform (1) to move upward synchronously, and the driving component (2) stops working when the adjusting element (4) and the cup body (101) move upwardly in place; the equipment platform (1) continues to move upward until the clamping part (4) is detached from the cup body (101), at this time the equipment platform (1) stops driving the clamping part (5) upward, and then the cup body (101) is removed and vacuumed to obtain a double-layer fair mug.
