Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic moulds, in particular to a paper-plastic mould with which products are easy to fall off. Background Art

[0002] Paper-plastic molds are the key to the production of pulp molded products. However, when using existing paper-plastic molds to produce high-quality packaging products, due to the high requirements for the appearance of high-quality packaging products, filter holes cannot be set at the molding features of the paper-plastic molds, which results in vacuum suction when the product is demolded, making demolding difficult, affecting product quality and production cycle. In addition, when using existing paper-plastic molds to produce paper mold products, manual demolding is required, and a robot suction cup cannot be used, making demolding difficult and posing a safety hazard.

[0003] In the prior art, a Chinese patent document with a publication number of CN208121481U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a paper-molding mold for molding paper mold products, which includes an upper mold and a lower mold. When the upper mold and the lower mold are molded together, the upper mold and the lower mold cooperate to form a molding cavity. The paper-molding mold also includes a blow plate, which is fixed on the side of the upper mold away from the lower mold. At least one blow hole is provided on the blow plate, and at least one first vent hole is provided on the upper mold. One end of the first vent hole is connected to the blow hole, and the other end of the first vent hole is connected to the molding cavity. The paper-molding mold of the utility model has a blow plate, and the blow plate can blow air to the surface of the paper mold product in the molding cavity through the blow hole and the first vent hole on the upper mold, so that the paper mold product can be easily demolded, which can effectively shorten the demolding cycle and reduce safety hazards.

[0004] In order to solve the problem that manual demoulding cannot be performed using a robot suction cup, making demoulding difficult and posing a safety hazard, the prior art uses a method of blowing air to the surface of the paper mold product in the molding cavity through the blowing holes and the first air holes on the upper mold. However, the paper mold product is prone to stickiness and scalding during heat processing, which in turn leads to the problem that the product is easily torn due to stickiness during demoulding, and the high temperature may injure the staff.
