Description

Technical Field

[0001] The utility model relates to the technical field of molding dies, in particular to a pulp molding die. Background Art

[0002] A pulp molding die is a tool for producing pulp molded products. Pulp molded products are usually formed by pouring an aqueous solution containing a certain proportion of fibers into the die, and then through a specific process, such as adsorption molding or compression molding, to form paper products with a certain shape and structure. These products also need to go through further processing, such as drying, shaping, etc. steps after molding to obtain the final finished product.

[0003] After retrieval, the text of the patent number "CN112853819A" mentions that "The present invention provides a non-transfer die for pulp molded products, belonging to the technical field of machinery. It solves the technical problem of low manufacturing efficiency of existing pulp molded products. The present invention includes an upper die and a lower die. The upper die is made of a heat-conducting solid metal material. An insulating seat for maintaining the heat of the upper die is provided on the lower die. The shape of the upper surface of the insulating seat matches the shape of the molding surface of the upper die to form a cavity. The insulating seat contacts the lower die and is supported by the lower die. A wire mesh die with a shape matching the upper surface of the insulating seat is provided on the upper surface of the insulating seat. A number of through water holes are provided on the insulating seat, and a number of through holes are also provided at the bottom of the lower die. The through holes are communicated with the above-mentioned water holes. After using this non-transfer die, from the wet blank forming to the hot pressing and drying and shaping, there is no need to transfer through a transfer die, so that the wet blank forming and heating and shaping are completed in one processing, saving the intermediate transfer step and having higher efficiency." When in use, the wet blank is heated and dehydrated and shaped through the heat-conducting solid metal material and the water holes. The wet blank completes the work of forming and heating and shaping in one processing without transferring the wet blank, saving the intermediate transfer step and improving the efficiency of manufacturing the die. However, during the die plastic process, the temperature of the die is relatively high after heating, and it is inconvenient to directly contact the die to take the mold. It is necessary to wait for the die to cool down before taking the mold, which reduces the production efficiency. Moreover, due to the single fixation of the die, there is a problem of difficult die replacement.

[0004] Therefore, we provide a pulp molding die to solve the above problems. Summary of the Utility Model

[0005] This application provides a pulp molding die, which solves the problems of inconvenient mold taking due to high temperature and inconvenient mold replacement.

[0006] This application provides a pulp molding die, including a bottom shell and a molding die mechanism. The molding die mechanism is installed on the upper side of the bottom shell;
