Abstract

The invention is applicable to the technical field of plastic products and provides a set-top box, aiming to solve the problem that a weld line appears outside a plastic shell of a set-top box in the prior art. The set-top box comprises a first shell and a second shell which are made of plastics and formed by a point plastic filling mode. The first shell and the second shell are arranged oppositely and form an accommodating cavity for accommodating an electronic device. The first shell comprises an upper cover and a first enclosure wall, and the second shell comprises a lower cover and a second enclosure wall. The upper cover is provided with a plastic filling port allowing a mould to perform external plastic filling treatment, the plastic filling port is located at the center of the upper cover, and the set-top box further comprises a cover plate which is arranged above the upper cover in a covering manner so as to cover the plastic filling port. Through the first shell and the second shell formed by the point plastic filling mode, direction and length of a weld line are controlled conveniently, and the cover plate is arranged on the upper cover of the first shell to cover the plastic filling port, so that the weld line formed on the surface of the first shell is hidden, namely, brightness of the outer surface of the set-top box is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of plastic products, in particular to a set-top box. Background technique [0002] With the development of intelligence and networking of set-top boxes, the shells of set-top boxes are gradually getting rid of the traditional iron shells, and the application of plastic shells has begun to be extensive. [0003] However, the use of plastic shells is generally prone to weld line problems, which affect the appearance of the product. The weld line is a linear trace on the surface of the plastic shell. It is caused by the diversion and convergence of several streams of material during injection or extrusion. The appearance quality and mechanical properties of the plastic shell. [0004] Usually, the following methods are used to eliminate the weld line. The first is to control the diffusion of the weld line to the surrounding direction of the glue inlet point by feeding glue in the center of the plastic shell, ...
