Forming machine for boxes with covers and special mold

Abstract

The invention discloses a forming machine for boxes with covers and a special mold. The scheme that a box body and a cover body are formed sequentially is adopted. Particular technique includes final form arrangement with a concave mold matching with a box, a convex mold is divided into two separate bodies, one separate body is a box body convex mold, the other separate body is a cover body concave mold, the two separate bodies are respectively provided with driving portions, and accordingly the technical scheme of sequential stamping can be met. Correspondingly, a prepressing component is assembled on one separate body, namely the prepressing component is arranged on the separate body which is not in stamping at first, accordingly, after the separate body which is in stamping at first is positioned in place, a workpiece of a corresponding portion is jacked into the corresponding concave mold by the other separate body, detention of the corresponding workpiece is reduced in the process, normal mobility can be realized, mobility required to be realized is greatly reduced when the workpiece of the corresponding separate body is stamped and formed, and the problem of drawing breakage due to high mobility required in a forming process is solved.

Description

technical field [0001] The invention relates to a forming machine for a box with a lid and a special mold, which is mainly used in an environment-friendly box with a lid, especially for disposable utensils, such as a disposable lunch box with a lid. Background technique [0002] Because foamed plastics are difficult to recycle, have poor environmental degradability, and contain harmful ingredients to the human body, production, sale and use in catering industry appliances have been banned since January 1, 2001. [0003] It is replaced by environmentally friendly tableware. Environmentally friendly tableware is divided into three categories according to the source of raw materials, production process, degradation method and recycling level, namely: biodegradable categories: such as paper products (including pulp molding type, cardboard coating type), edible Powder molding type, plant fiber molding type, etc.; light / biodegradable materials: such as light / biodegradable plastics...

AI Technical Summary

Problems solved by technology

Therefore, the volume of the formed conjoined lunch box only depends on the box body, which seriously affects the capacity of the lunch box

At the same time, because the cover body is not molded, the cooperation effect between it and the box body when containing items is poor, and the overall storage capacity is low. This type of lunch box cannot be accepted by consumers.
