Problems solved by technology
However, the paper molding industry is still a new industry, and the molding and processing technology of its products still needs to be improved and improved.
For example, the current pulp molding molds usually use Teflon-coated surface treatment for smooth demoulding. This process has two main disadvantages: (1) After a certain number of productions, the surface coating of the mold is severely worn, and the coating needs to be removed again. Layering and spraying Teflon is time-consuming and laborious, which greatly affects its production efficiency; (2) Teflon is easy to volatilize toxic materials at high temperatures, which is harmful to the human body and is not environmentally friendly

Embodiment
[0039] according to figure 1 The steel pulp molding mold shown includes a core base 1 and a cavity base 2, the core base 1 and the cavity base 2 are matched, and the surfaces of the core base 1 and the cavity base 2 are vacuum plated with Titanium nitride coating 3 , a titanium carbide transition layer 4 is provided between the core base 1 and cavity base 2 and the titanium nitride coating 3 .
[0040]In the process of empty-plating titanium carbonitride on the surface of the steel pulp forming mold, the outer surface of the substrate is firstly polished with sandpaper to remove impurities such as oil and rust on the surface of the substrate, and then the rough polished The substrate is put into the closed sandblasting machine processing cabin, and the powdery sand particles (1-4mm in diameter) are transported from one place to another by compressed air, and the kinetic energy of the sand particles is converted into potential energy, so that the high-speed moving The sand par...

The invention discloses a technology for vacuum plating of titanium carbonitride on the surface of a steel paper pulp mold. The titanium carbonitride plated mold comprises a mold core base body and amold cavity base body; the mold core base body is matched with the mold cavity base body, the surfaces of the mold core base body and the mold cavity base body are both subject to titanium nitride coating vacuum plating, a titanium carbide transition layer is arranged between the titanium nitride coating and the mold core base body with the mold cavity base body, and the vacuum film coating process comprises the following steps of S1, base body treatment, wherein abrasive paper is adopted to polish the surface of a base body, and oil dirt, rust and other impurities on the surface of the base body can be removed; through the titanium carbonitride vacuum plating process, the mold has the higher hardness, meanwhile, the combination strength of the toughness of the coating and the base body isimproved, impact resistance and wear resistance of the coating can be improved, the service life of the mold is prolonged, the coating process is easily mastered, and the production process is stableand reliable.
Description
technical field [0001] The invention relates to the field of pulp molding moulds, in particular to a process for vacuum-plating titanium carbonitride on the surface of a steel pulp molding mould. Background technique [0002] Pulp molded products made of annual herbaceous plant fiber as the main raw material meet the needs of modern society for sanitation, convenience, speed and health. With the characteristics of being practical, non-toxic, completely degradable after being discarded, and returning to nature, It has a broad development prospect, so the pulp molding industry is an environmental protection industry that is conducive to the sustainable development of social economy. [0003] The paper molding industry is similar to the papermaking industry. Its molding process has several stages of pulp preparation, molding dehydration, and drying and setting. However, paper molding production is different from papermaking. People also call it three-dimensional papermaking. H...
