Structure for improving deformation of control box product made of PP (polypropylene) material

Technical Field

The utility model relates to the technical field of medical treatment, furniture and industrial power supply control boxes, in particular to a structure for improving deformation of a control box product made of a PP material.

Background

The pp material is polypropylene, the polypropylene is a non-toxic, odorless and tasteless milky-white high-crystalline polymer, the density is only 0.90 to 0.91g/cm3, and the polypropylene is one of the lightest varieties of all plastics at present. It is particularly stable to water, with a water absorption of only 0.01% in water and a molecular weight of about 8 in the case of 15 ten thousand. Has good formability and is widely used as a production material for medical treatment, furniture and industrial power supply control boxes.

In the existing control box product structure, after a PP material is molded, due to uneven shrinkage and stress factors of a plastic material, the product is seriously warped and deformed, the overall appearance and the dimensional stability are damaged, and the product assembly is abnormal, so that the problem of structural solution of deformation improvement of the control box product made of the PP material is solved.

SUMMERY OF THE UTILITY MODEL

The present invention aims to provide a structure for improving deformation of a control box product made of PP material, so as to solve the problems mentioned in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a structure that control box product of PP material improves deformation, includes the box body, the inner chamber has been seted up to the inside of box body, the both sides of inner chamber inside are equidistant to be provided with three reference columns, the both sides of the inboard bottom of inner chamber all are seted up flutedly.

Preferably, the box body is integrally formed by injection molding of a PP material.

Preferably, the width of the groove ranges from 0.56 to 0.85 of the side wall of the box body.

Preferably, the depth of the groove ranges from 0.28 to 0.6 of the bottom wall of the box body.

Preferably, the design of the demoulding inclination of the side wall of the groove is 0.5-5 degrees.

Compared with the prior art, the utility model has the beneficial effects that: the utility model has scientific and reasonable structure and safe and convenient use, and can reduce the slight deformation of the PP material after the product is molded, and ensure stable size, good appearance and smooth assembly.
