Description

Double-layer cup injection molding machine assembly tool 【0001】

This creation is about a double-layer cup injection molding in-mold assembly machine, especially a mechanism that can be injection molded to make a double-layer cup.

【0002】

Plastic cups are widely used in modern people's lives. Because they are easy to use, light and disposable, they play an important role in banquets and dining venues. Because the plastic cup has a thin wall, it can not achieve too good heat insulation effect. Therefore, there is a double-layer plastic cup with a hollow insulating space to improve the missing, and the inner and outer double-layer cups are produced. The combination creates a spacing between the cups, which in turn provides better thermal insulation and is more textured than a single layer cup.

[0003]

However, in the prior art, the production of the double-layer cups mostly requires three steps of injection molding, and the conventional production mainly uses ultrasonic welding to weld the inner and outer cups by ultrasonic or rotary welding. Bonding, and ultrasonic processing is a low-cost manufacturing technique, but its sealing is insufficient, it is impossible to make a container with strict airtightness requirements, and although the rotary welding can achieve high airtightness, it is rotated by rotation. The friction method produces welding, so it is limited to the product used in the ring-shaped appearance, and there are disadvantages thereof. In addition, it is possible to additionally coat the high-temperature plastic of the same material for fixing by means of injection molding at the joint of the two cups, but In this way, it is necessary to do two operations on the injection machine, the operation is complicated, and it is time-consuming and labor-intensive.
