Manufacturing method for injection molding alloy material hollowed-out checkered plate

Abstract

The invention discloses a manufacturing method for an injection molding alloy material hollowed-out checkered plate. The method includes the following steps that melt plastification is performed, an alloy material is heated to 220-250 DEG C, and then the alloy material in a molten state for standby application; injection molding is conducted, and the molten alloy material is injected into a mold within 8-10 seconds in an injection mode under the conditions that the pressure is 85-110MPa and the flow is 85%-90%; cooling and demolding are carried out, the mold filled with the alloy material is subjected to overall demolding after being cooled, and thus the hollowed-out checkered plate is obtained; and the melting point of the alloy material ranges from 170 DEG C to 220 DEG C. By the adoption of the manufacturing method, products can be obtained in the one-time injection molding mode, and the method is suitable for large-scale batch production. The obtained hollowed-out checkered product is lasting in color, non-toxic and harmless in material, safe, environmentally friendly and capable of being cleaned easily. The hollowed-out checkered plate cannot be deformed after being used for a long time, color fading is not likely to happen, and installation is convenient.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a method for manufacturing a hollow grate, in particular to a method for manufacturing an injection-molded alloy material hollow grate. Background technique [0002] Hollowing is a kind of engraving technique, processing a hollowed out handicraft. Traditional hollowed-out lattices are mostly wood products, and its production process features are: material selection-sample preparation-carving-polishing-painting-aging; the process characteristics determine that it is time-consuming, material-intensive, difficult and costly. Far from meeting the needs of the market. [0003] In recent years, with the scientific development of machinery manufacturing and electronic automation, the technology and technology of hollowed-out products are no longer manual workshops; modern electronic automatic engraving technology has been widely used, and the appearance of plywood, fiberboard and particleboard ...

AI Technical Summary

Problems solved by technology

[0010] (3) Perishable: wood is easily corroded by fungi in poorly ventilated and humid conditions; fungi are divided into three types: mold, discoloration bacteria and decay bacteria.

[0011] (4) Not resistant to corrosion: wooden materials are not resistant to acid and alkali, and most chemical reagents and liquids can cause dehydration and carbonization of wood products, causing discoloration, carbonization and decomposition of wooden products;

[0012] (5) Not environmentally friendly: the adhesives made of machine-made panels and the paints and paint thinners used in product painting all contain harmful substances such as formaldehyde, urine aldehyde, toluene, and ethyl benzene, which are harmful to health;

[0013] (6) Large waste: Whether it is hand-carved or mechanically carved, the characteristics of its manufacturing process determine that it is time-consuming and wasteful of materials, and the utilization rate of general materials is below 50%.
