Edge strengthening blow molding panel

Abstract

An edge strengthening blow molding panel comprises an upper layer plate, a lower layer plate and protruding edges formed on the periphery of the panel, and a hollow integrated structure is formed between the upper layer plate and the lower layer plate through blow molding. The edge strengthening blow molding panel is characterized in that the outer edge of the upper layer plate extends downwards to form the outer side walls of the protruding edges, the outer edge of the lower layer plate extends downwards to form the inner side walls of the protruding edges, the protruding edges are provided with solid fusion portions which enable the joint lines at the protruding edges to disappear due to the mutual infusion of the outer side walls and inner side walls of the protruding edges, and the solid fusion portions are distributed in the length direction of the protruding edges at intervals. The edge strengthening blow molding panel has the advantages that the protruding edges of the blow molding panel are provided with the solid fusion portions which enable the joint lines of the protruding edges to disappear, the structural strength of the protruding edges can be obviously enhanced, and the problem that the joint lines are prone to fracturing can be fundamentally solved; in addition, the solid fusion portions are distributed in the length direction of the protruding edges at intervals, the protruding edges are provided with hollow portions where the outer side walls and the inner side walls are not fused into the solid fusion portions, screws can be installed on the inner side walls, corresponding to the hollow portions, of the protruding edges, and the installation is very convenient.

Description

technical field [0001] The invention relates to a blow-molded panel, in particular to an edge-reinforced blow-molded panel. Background technique [0002] Blow molding products are light in weight due to their hollow structure. In addition, due to their material, shape and structure, they have the advantages of strong rigidity, good impact resistance, and not easy to damage. In recent years, blow molding products have been used in many fields. Widely used, especially blown panels, more widely used. [0003] Existing blow-molded panels generally include an upper plate, a lower plate and a flange formed around the panel, and the space between the upper plate and the lower plate is blown into a hollow structure. The bottom of the panel is usually distributed with many irregularly arranged concave support points of different shapes and sizes to increase its strength. However, due to the limitations of the blow molding process, there are still some potential failure points that ...

AI Technical Summary

Problems solved by technology

The junction of the parting line is to rely on the upper and lower dies of the mold to close together to form a relatively thick knife edge, so that the plastic can be squeezed to the parting line so that the parting line can stick there, and the inside and outside of the product parting line The current situation of concave from the inside to the outside appears at the junction of the parting line, which makes the parting line more fragile. Experiments have shown that the blow molding panel is the most vulnerable position at the parting line, the structural strength is the lowest, and it is most likely to be broken due to impact

In order to overcome the above problems, people often increase the structural strength of the panel by increasing the thickness of the panel, but the defect of using a thickened panel is that the panel looks thicker. Improvement, but the rigidity and structural strength of the edge of the panel cannot be improved, and the problem that the parting line of the blow-molded panel is easy to break has not been resolved
