Embodiment Construction

[0075] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but only to illustrate the essence of the technical solutions of the present invention.

[0076] Figure 1-2 A schematic structural view of a plate-shaped member 100 according to an embodiment of the present invention is shown. The plate-shaped member 100 includes a plate-shaped main body 1 and a steel pipe 2 built in the plate-shaped main body 1, and the steel pipe 2 serves as a reinforcement. Both ends of the steel pipe 2 are detachably connected with plugs 3 for blocking the steel pipe. Plug 3 protrudes to a predetermined length Lc at both ends of steel pipe 2 (such as Figure 5 shown). The outer circumference of the steel p...

Abstract

The invention relates to a plate-like part and a manufacturing method thereof. The plate-like part comprises a plate-like part body and reinforcing parts arranged inside the plate-like part body, and the outer surface of each reinforcing part is wrapped with a layer of medium. The manufacturing method includes the following steps that the outer surface of each reinforcing part is wrapped with the layer of medium; each reinforcing part is placed in a mold, and a first auxiliary structure and a second auxiliary structure are arranged at the two ends of each reinforcing part correspondingly and protrude out of the two end faces of the reinforcing part by a preset length in the axial direction of the reinforcing part; injection molding operation is carried out through the mold, so that the reinforcing parts are arranged inside the formed plate-like part body; and after injection molding, the auxiliary structures are removed. The plate-like part has the advantages of being good in pressure bearing effect, small in thickness and safe in production due to the adoption of the mode that the reinforcing parts are wrapped with the media in advance, the production cost is lowered, and the problem that a plate-like part obtained through existing production techniques is prone to shrinkage cracks is solved.

Description

technical field [0001] The invention relates to logistics equipment, in particular to pallet products and folding cardboard boxes. Background technique [0002] The base or side panels of pallets and folding cardboard boxes currently on the market are usually reinforced with steel pipes. One way of placing the steel pipes in the base or side panels is to insert the steel tubes into the base or side panels after the base or side panels have been manufactured. Another way is to first place the steel pipe between the upper and lower plates that form the side plate or base, and then weld the upper and lower plates to each other to form the base or side plate. Another way is that the base or the side plate is manufactured by integral injection molding, and the steel pipe is directly put into the injection molding, and the steel pipe is built into the base or the side plate after the injection molding is completed. There will be a problem in the last kind of scheme, that is, whe...
