Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an inverted mold. Background Art

[0002] As a tool for producing plastic products, injection molds can give plastic products a complete structure and precise dimensions. Injection molds generally consist of two parts: a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. Due to the special structure of the finished product or the appearance requirements of the finished product, the injection and ejection are on the same side of the finished product. Such a mold structure is called a flip mold. In particular, flip molds are particularly suitable for high requirements on the outer surface of the injection molded product, such as the flatness, no marks and smoothness of the outer surface of the product. The pouring system and demoulding mechanism of the flip mold are both located in the rear mold of the mold, that is, the injection and ejection are located on the same side of the injection molded product. A structural improvement of the flip mold is proposed in the utility model with the Chinese patent publication number CN214726098U. After studying the existing technology and the above patent, it was found that the molding efficiency of the existing flip mold needs to be improved. Therefore, a flip mold is proposed herein.
