The invention discloses a paper pulp molding hot-press molding demolding net, which comprises a mold body and a mold hole; the die body comprises a die bottom, a die wall, a die edge and an extension wall which are arranged from bottom to top; the die holes are arranged on the die bottom, the die wall, the die edge and the extension wall, the die holes are elongated holes uniformly distributed on the die body, the cross section of the die holes is in a diamond shape, and the die holes are uniformly arranged in a staggered manner; by selecting one of the raw materials of steel, aluminum and iron as the raw material of the plate, the service life is obviously prolonged and is more than 50 times of the service life of a net die made of the traditional gauze, so that the shutdown frequency caused by replacing the net die is reduced, the production efficiency is greatly improved, unnecessary waste is reduced, and the consumed cost is greatly reduced; the product has high hardness, high precision and smooth and beautiful surface.
Description
Technical Field
The invention relates to the technical field of paper pulp molding production, in particular to a paper pulp molding hot-press forming demolding net and a manufacturing process thereof.
Background
In the forming process of paper pulp moulded tableware, the shaping of its product is mainly completed by means of shaping mould, when it is worked, the wet paper blank is firstly squeezed in the shaping mould with net mould, about 20% of water is squeezed and discharged, at this time the water content in the wet paper blank is about 50-55%, then the wet paper blank is heated in the mould, the rest water is vaporized and discharged, after a certain period of time, the paper pulp is dried and shaped in the shaping mould so as to obtain the invented product.
In the production of paper pulp molding products, the sizing net mold adopts gauze, although the water leakage and air exhaust performance of the gauze is good, the strength is poor, the gauze between the upper mold and the lower mold is easy to extrude and wear to break along with the continuous mold closing and mold opening of the upper mold and the lower mold in the production, thereby increasing the production cost and reducing the production efficiency due to frequent shutdown and net mold replacement; the invention aims to find a novel paper pulp demolding net, which can meet the requirements of water leakage and air permeability of a production process in the production process of products, and has higher strength and long service life.

The technical scheme adopted by the invention for solving the technical problems is as follows: a pulp molding hot-press molding demolding net comprises a mold body and a mold hole; the die body comprises a die bottom, a die wall, a die edge and an extension wall which are arranged from bottom to top; the die holes are formed in the die bottom, the die wall, the die edge and the extension wall, the die holes are elongated holes which are staggered and uniformly distributed on the die body, and the cross section of each die hole is in a diamond shape.
The manufacturing process of the pulp molding hot-press molding stripping net comprises the following steps:
the method comprises the following steps: blanking: putting a plate with the thickness of 0.2-0.6mm on a conveyor belt, and advancing the plate to a stamping progressive die;
step two: cutting; trimming and separating the plates through a trimming separation module of the progressive stamping die;
step three: punching; punching and positioning the plate through a punching module of the punching progressive die; the aperture is 0.2-1.0mm, and the hole spacing is 2-6 mm;
step four: stretching; stretching the blank by a stretching and shaping module of a stamping progressive die;
step five: heat treatment; the plate is slowly heated to 800 ℃ and is slowly cooled along with the furnace after heat preservation for 30min, and then is taken out of the furnace and cooled to room temperature.
As a further improvement of the invention, the raw material of the plate in the step one is one of stainless steel, copper, aluminum and iron.
As a further improvement of the invention, the thickness of the plate in the first step is 0.55 mm.
As a further improvement of the invention, the aperture in the third step is 0.4mm, and the hole spacing is 4 mm.
