Problems solved by technology

[0002] In the injection molding process of many common daily necessities such as notebooks, the main purpose of the injection nut is to inject the nut into the plastic part, which can form an internal thread in the plastic part, which is convenient for installing and fixing other parts. The working method is to heat the nut and embed it. Insert it into the plastic part or directly use mold injection molding. During the injection molding process, the nut is hot-injected into the plastic and wrapped. After cooling, the plastic and the nut are bonded together. In order to ensure the firmness of the bond, there is a ring of embossing on the outside of the nut. After forming, the friction and occlusal force of the plastic and the nut are increased, while the existing embossed shape is a cylinder, the friction and occlusal force are insufficient, resulting in the weak joint between the plastic and the nut, which is easy to appear when fixing other parts Nut detachment phenomenon

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] figure 1 , figure 2 and image 3 They are the side structure schematic diagram, the other side structure diagram and the bottom surface structure diagram of an anti-slip injection molding nut of the present invention; as shown in the figure, the anti-slip injection molding nut includes a nut body 1, and the nut body 1 is provided with an equatorial groove 12 , a plurality of anti-slip protrusions 11 are arranged symmetrically on both sides of the equatorial groove 12 . The anti-slip protrusions 11 on each side are arranged in parallel. Preferably, two adjacent anti-slip protrusions 11 on each side are arranged symmetrically. The included angle between each of the anti-slip protrusions 11 and the equatorial groove 12 is 30°. The width of the equatorial groove 12 is 1 / 4 of the width of th...

Abstract

The invention discloses an anti-slip injection molding nut. The anti-slip injection molding nut comprises a nut body which is provided with an equatorial groove, and a plurality of anti-slip protrusions are symmetrically arranged on two sides of the equatorial groove. The equatorial groove is formed in the middle of the nut body, the anti-slip protrusions are arranged on the two sides of the equatorial groove, and therefore friction force and meshing force of plastic and the nut are enhanced, connection firmness of the plastic and the nut is improved, and the nut will not break away when fixing other components.
