Flanging machine mold

Abstract

The invention discloses a flanging machine mold. The flanging machine mold comprises an upper mold device and a lower mold device, wherein the upper mold device comprises an upper mold and a vertically-arranged main shaft, a flanging sleeve and a double-taper sleeve are arranged below the upper mold, and the upper end part of a guide rod sleeved with an upper mold reset spring penetrates through a middle hole of the double-taper sleeve to be in threaded connection with the middle of the lower end of the upper mold; and the lower mold device comprises a lower mold and a lower mold shaft, and the lower end of the lower mold shaft is connected with a driving mechanism used for driving the lower mold shaft to move up and down along the axis so as to complete mold assembly or separation of the lower mold shaft and the upper mold device. According to the flanging machine mold, the flanging perpendicularity of an inner container is better, the production efficiency is higher, and the rejection rate is lower, so that the outer diameter of a housing corresponding to the flanging machine mold can be reduced, the materials are saved, the cost is reduced, and a vacuum cup is smaller and more exquisite on the premise of the same capacity.

Description

technical field [0001] The invention relates to a mold for a water cup, in particular to a flanging mold for a water cup liner. Background technique [0002] In order to prevent the mouth of the metal thermos cup from scratching the user, the liner of the thermos cup needs to be flanged outwards, and then the outer shell of the liner needs to be fitted. [0003] For conventional thermos cups that adopt the welding process of arc mouth after flanging, since the outer diameter of the flanging of the mouth of the liner is larger than the inner diameter of the mouth of the outer shell after the mouth is rotated, the inner liner cannot be inserted into the outer shell for matching welding, so the inner liner needs to be welded first After the liner is put into the shell, the mouth of the inner liner is flanged, and finally the mouth is welded. For the above process, the currently widely used flanging machine is a horizontal flanging machine, such as "a stainless steel cup cup mo...

AI Technical Summary

Problems solved by technology

The efficiency of the horizontal flanging machine is low, and the verticality between the flanging and the cup body is poor, which leads to the non-parallel between the inner tank and the outer shell after welding, the gap is uneven, and even the wall is bumped, resulting in defective products.

Based on the above defects, in order to avoid the occurrence of defective products caused by bumping into the wall, the only way to increase the size of the cup shell is at present

This not only wastes material, but also increases the size of the product
