Problems solved by technology
However, when this kind of injection plug is injection molded, it is often caused by excessive filling, excessive injection pressure or insufficient clamping force, etc., which will cause parting line traces on the side wall of the plug, and even flash.
The production of the mold line not only affects the exquisite appearance of the product, but also greatly reduces the quality of the product, and the mass production of such power plugs with the mold line greatly increases the amount of plastic used, thereby increasing the production cost

Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0029] refer to figure 1 , is a non-marking power plug disclosed in the present invention, comprising a plug body 1 with a smooth outer wall, and anti-skid grooves 2 are respectively opened on both sides of the plug body 1, and the anti-skid grooves 2 are provided for the plug body 1. The position of the clamping line during injection molding, two mutually parallel conductive inserts 3 are fixed on the plug body 1, and the end of the plug body 1 away from the conductive inserts 3 is provided with a protective cover 4, the protective cover 4 is provided with electric wires electrically connected to the conductive insert 3 .
[0030] Among them, refer to figure 2 with image 3 , the plug body 1 includes a plastic body 11, a PP inner mold 12 and a fixing plate 13, the two conductive inserts 3 are mounted on the fixing plate 13, and the PP inner mold 12 compl...

The invention relates to a traceless power plug, which comprises a plug body with a smooth outer wall. Anti-skid grooves are provided on both sides of the plug body. The anti-skid grooves are the position of the mold line of the plug body during injection molding. There are two conductive inserts parallel to each other. The end of the plug body away from the conductive inserts is provided with a protective sleeve, and the protective sleeve is provided with electric wires electrically connected to the conductive inserts. At the position of the clamping line during injection molding, the two sides of the plug body are squeezed by the slider to form an anti-skid groove. On the one hand, the clamping line during injection molding is eliminated, the appearance quality of the product is improved, and raw materials are saved at the same time. , and effectively eliminate the gas in the plastic, avoid the generation of air bubbles, and improve the structural strength of the socket body; The function of protection, the design is ingenious, and has strong economic promotion value.
Description
technical field [0001] The invention relates to the technical field of power plugs, in particular to a traceless power plug and a production process thereof. Background technique [0002] Power plug refers to the device that devices such as electrical appliances are connected to power supply. Power sockets and plugs vary in shape, class, size and type depending on the country and region. Every country has standards set by the government. The power plug is also called the power cord plug, and the English is power plug. Used in various fields, in various countries. Depending on the purpose of the power plug, the power cord plug can be used at 250V, 125V, and 36V, and can be used at 16A, 13A, 10A, 5A, and 2.5A depending on the current. The frequency is generally 50 / 60Hz. [0003] In the prior art, power plugs can be roughly classified into conversion power plugs, injection molding power plugs and assembly power plugs. The injection molded plug is one of the most used plug...
