Novel shelf and manufacturing method thereof

Abstract

The invention discloses a novel shelf and a manufacturing method thereof. The shelf comprises an outer framework and an inner sieving plate, and the outer framework is arranged on the peripheral edgeof the inner sieving plate. The inner sieving plate comprises first partition bars and second partition bars. The second partition bars are crossed with each other and further integrally formed to bearranged in gaps between the two adjacent first partition bars by means of injection molding. The method includes the steps that a, a mold is cleaned; b, the mold is mounted; c, the mold is closed; d,a rotating mechanism is installed; e, first-time injection molding is conducted; f, first-time mold rotation is performed; g, second-time mold rotation is performed; h, third-time mold rotation is performed; i, fourth-time mold rotation is performed; j, second-time injection molding is conducted; and k, pressure maintaining glue returning is carried out, then the mold is cooled, afterwards, moldopening and demolding are conducted and an injection molding finished product is taken out. According to the novel shelf and the manufacturing method thereof, the injection molding time of the secondpartition bars can be shortened; meanwhile, the strength between the second partition bars is improved, and the breaking condition of the inner sieving plate during integrated injection molding is prevented; and in the manufacturing method, the speed for molten plastics to be filled into the whole cavity can be increased and injection molding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and in particular relates to a novel shelf and a manufacturing method thereof. Background technique [0002] There are more than one million species of insects in nature, which are widely distributed and have a huge overall biomass. They play complex and important roles in ecosystems or food chains. Some insects can manufacture or provide raw materials, food or medicine for humans, and their functions and values ​​are worth exploring. [0003] Human beings have used and studied insects for a long time, especially since modern times, the research and development efforts have been accelerated. Natural insects in nature can no longer meet the needs of human beings, so insect breeding has gradually received attention. The purpose of breeding has the following aspects: (1) to provide raw materials for humans; (2) for food or medicine; (3) to provide animal protein feed; (4) to cultivate natu...

AI Technical Summary

Problems solved by technology

However, the spacer of this type of shelf is prone to breakage during injection molding, which affects the feeding process of insects; and the flow of molten plastic is relatively slow, resulting in slow filling of the entire cavity with molten plastic and reducing injection molding efficiency.
