Step seedling culture container and manufacturing mold thereof

Abstract

The invention provides a step seedling culture container and a manufacturing mold thereof, belongs to the technical field of material compression molding, and mainly solves the problems of poor stability and body deformation in the prior art. The container comprises an inner wall large-opening inclined plane, an inner wall step, an inner wall small-opening inclined plane, an outer wall step and a container body lower portion outer wall, the inner wall step is connected with the lower portion of the inner wall large-opening inclined plane, the upper end of the inner wall small-opening inclined plane is connected with the inner wall step, the lower end of the inner wall small-opening inclined plane is connected with the container bottom, the container bottom middle hole is located in the middle of the container bottom, the lower end of the outer wall of the upper portion of the container body is connected with the outer wall step, the upper end of the outer wall of the lower portion of the container body is connected with the outer wall step, and the lower end of the outer wall of the lower portion of the container body is connected with the outer wall of the container bottom. The step seedling culture container manufacturing mold comprises a combined female mold and a male mold, and the combined female mold comprises a female mold outer sleeve and a female mold inner sleeve; and the diameter of the outer wall of the female mold inner sleeve slideway is matched with the inner diameter of the lower cylindrical surface of the outer sleeve inner wall.

Description

technical field [0001] The invention belongs to the technical field of material compression molding, and in particular relates to a stepped seedling raising container and a manufacturing mold thereof. Background technique [0002] In 2003, patent No. ZL03138791.8 invented the straw seedling pot with crop straw as raw material. [0003] In 2020, the patent No. 202011158321.6 addresses two problems in the production of straw containers in the original invention of the patent No. ZL03138791.8: ① When the container is set up and down, the lower container is easily damaged by pressure; ② The container inventory and transportation costs are high. Invented "a bowl shape design and production process for molding bowls with bulk materials", the cross-section of a single bowl and the schematic diagram of the upper and lower sets of bowls and bowls are shown in figure 1 as shown, [0004] However, later in the production practice of applying the patent No. 202011158321.6 technology t...

Problems solved by technology

[0003] In 2020, the patent No. 202011158321.6 aimed at the two problems of the original invention of the patent No. ZL03138791.8 in the production of straw containers: ①When the container is set up and down, the lower container is easily damaged under pressure; ②The container inventory and transportation costs are high

[0004] However, later in the production practice of applying the patent No. 202011158321.6 technology to invent and produce straw containers, it was found that: ① According to the method invented by the patent No. 202011158321.6 to design the container shape and make the container, the thickness of the container wall should be enhanced to enhance water erosion resistance during the seedling immersion process capacity, it is necessary to increase the angle between the container wall and the bottom plane, and the result will inevitably form a container with a large diameter and a short height; There is a problem of poor stability; ③After the container is molded and dried, there is a problem of shape deformation, and the upper and lower sets of the container and the container are not ideal
