Embodiment 1

[0022] After the paper cup 13 is put into the die 12, the lifting plate 8 starts to move downward under the action of the press, and the stop post 11 stops moving downward after touching the upper end surface of the forming die 12, and the inner sliding sleeve 5 is positioned at the limit block. Under the action of 11, the downward movement is stopped simultaneously; the outer sliding sleeve 7 and the sliding push rod 1 continue to move downward with the lifting plate 8, that is, relative motion is produced with the inner sliding sleeve 5 . As the lifting plate 8 continues to fall, the tapered lower end of the sliding mandrel 1 begins to contact the tapered through hole at the center of the forming punch 15, and pushes each module of the forming punch 15 to slide outward while moving downward. , thereby completing the forming process of the water injection line of the paper cup 13 in the forming die 12 . After the molding process is completed, the lifting plate 8 moves upward ...

Abstract

The invention discloses a prop opened type water injection line forming mechanism. The prop opened type water injection line forming mechanism comprises a sliding ejector rod, a fixed nut, a fixed plate, a fixed post, inner and outer sliding sleeves, a limited circular nut, a lifting plate, a guide post, a return spring, a limited post, a forming mould, a ring-shaped spring, a guide block, upper and lower fixed plates and an oil-free bearing. The prop opened type water injection line forming mechanism has the characteristics of being quick in forming, simple in action, free of an extra power mechanism for driving a convex mould to rotate, economical and efficient.

Description

technical field [0001] The invention relates to a forming mechanism for a stretched container water injection line. Background technique [0002] The inner wall of the paper cup is generally marked with a water injection line at the highest water level in the cup to prevent the cup from being filled with too much water. The traditional water injection line forming mechanism uses the rotary extrusion of the forming mold to make the water injection line. During the forming process of the water injection line, the punch is first driven by the press to drop into the die, and then the punch is driven by the motor on the inner wall of the die. It rotates more than one revolution, so the existing water injection line forming mechanism has the problems that the forming takes a long time, and the rotation of the punch needs to be driven by an additional power mechanism. Contents of the invention [0003] The purpose of this invention is to design a kind of expansion type water inj...
